  4. What's unusual in online disease outbreak news?

    PubMed Central

    2010-01-01

    Background Accurate and timely detection of public health events of international concern is necessary to help support risk assessment and response and save lives. Novel event-based methods that use the World Wide Web as a signal source offer potential to extend health surveillance into areas where traditional indicator networks are lacking. In this paper we address the issue of systematically evaluating online health news to support automatic alerting using daily disease-country counts text mined from real world data using BioCaster. For 18 data sets produced by BioCaster, we compare 5 aberration detection algorithms (EARS C2, C3, W2, F-statistic and EWMA) for performance against expert moderated ProMED-mail postings. Results We report sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), mean alerts/100 days and F1, at 95% confidence interval (CI) for 287 ProMED-mail postings on 18 outbreaks across 14 countries over a 366 day period. Results indicate that W2 had the best F1 with a slight benefit for day of week effect over C2. In drill down analysis we indicate issues arising from the granular choice of country-level modeling, sudden drops in reporting due to day of week effects and reporting bias. Automatic alerting has been implemented in BioCaster available from http://born.nii.ac.jp. Conclusions Online health news alerts have the potential to enhance manual analytical methods by increasing throughput, timeliness and detection rates. Systematic evaluation of health news aberrations is necessary to push forward our understanding of the complex relationship between news report volumes and case numbers and to select the best performing features and algorithms.

  5. [Cardiology online: impact and pitfalls of Internet medical news].

    PubMed

    Wood, Shelley M; Topol, Eric J

    2012-01-01

    Twenty years ago, the main sources for physicians seeking information on new procedures, drugs, or devices were meetings and medical journals. The dawn of the Internet radically transformed how news and information is delivered and absorbed, beginning with the launch of online journals back in the mid-1990s. A decade and a half later, physicians can learn about new innovations the moment they are made public, and they can get that news from their phones and tablets, their Twitter or Facebook accounts, or via their favorite blog or medical news web site. Along with the clear advantages of accessing new medical information any time of day comes the need for physicians to be aware of the pitfalls of online medical content and to have a heightened sense of responsibility when it comes to integrating information gleaned online into their medical practices.

    Absorption (one of three tools) (http://mc2.cchem.berkeley.edu/Chem1A/solar/applets/absorption/ index.html).

    Evaporative cooling in a Bose-Einstein condensation ( http://www.colorado.edu/physics/2000/applets/bec.html). Let's start with the spectrum--the electromagnetic spectrum, of course. Go to the EMSpectrum Explorer at http://mc2.cchem.berkeley.edu/chemcnx/light_energy/EMSpectrum /emspectrum.html. Not only do you get information about wavelength, frequency, and energy, but you also get a handy converter that will calculate frequency, wavelength, and energy when one value is entered. And there is more. For example, clicking on red light of 680 nanometers reveals that mitochondria, the power plants of cells, are about the same size as this wavelength, which is also used for photosynthesis. Interesting food for thought! From the EMSpectrum Explorer, go to the Light and Energy page at http://mc2.cchem.berkeley.edu/chemcnx/light_energy/index.html for three Colors of Light Tools. The Color from Emission tool ( http://mc2.cchem.berkeley.edu/chemcnx/light_energy/applets/emission/index.html) illustrates additive color by mixing differing amounts of Red, Blue, and Green light. Then look at the Color from Absorption tool at http://mc2.cchem.berkeley.edu/chemcnx/light_energy/applets/absorption/index.html. The image from the applet shows the white beam and three filters. Take out the blue, green, and red components by altering the scroll bars or text boxes. The third tool, Removing Color with a Single Filter from Colored Light at http://mc2.cchem.berkeley.edu/chemcnx/light_energy/applets/single/index.html, uses a single filter to take out various colors. Excellent for explaining the theory behind the operation of a basic spectrometer. The Light and Energy tools module, which received support from the National Science Foundation, has been developed under the direction of the ChemLinks Coalition--headed by Beloit College; and The ModularChem Consortium, MC2, headed by the University of California at Berkeley. The Project Director is Marco Molinaro from the University of California at Berkeley; the Project Manager is Susan Walden; Susan Ketchner and Leighanne McConnaughey are also members of the team for this excellent teaching site. For your information, all of the applets will soon be moving, along with the MC2 site, but the old addresses will still work. The next place to explore is Physics 2000 at http://www.colorado.edu/physics/2000/introduction.html. The introductory graphic is a harbinger of good things to come: move the negatively charged particle and see the water molecule spin in response to the position of the charged particle. One goal of the Physics 2000 Educational Initiative is to make physics more accessible to students and people of all ages. Sounds like a good goal for all sciences! One of the first sections is called Einstein's Legacy. Here you can find spectral lines explained in terms of team colors for rival football squads ( http://www.colorado.edu/physics/2000/quantumzone/index.html). Choose from 20 elements to see characteristic emission spectra. The cartoon teachers and students help explain emission spectra. Great applets compare the Bohr atom and the Schrödinger model as well as emission and absorption ( http://www.colorado.edu/physics/2000/quantumzone/schroedinger.html). Einstein's Legacy has many topics: X-rays and CAT Scans, Electromagnetic Waves and Particles, the Quantum Atom, Microwave Ovens, Lasers, and TV & Laptop Screens. Several topics also have sections for the advanced student. One of those advanced sections is part of the second major section of Physics 2000: The Atomic Lab. Two topics are Interference Experiments and Bose-Einstein Condensate. An applet illustrating Laser Cooling is at http://www.colorado.edu/physics/2000/bec/lascool1.html. Next go on to Evaporative Cooling at http://www.colorado.edu/physics/2000/bec/evap_cool.html. The cartoon professors begin the explanation with a picture of steam rising from a cup of hot coffee. Next is an applet with atoms in a parabolic magnetic trap at http://www.colorado.edu/physics/2000/applets/bec.html. The height of the magnetic trap can be changed in order to allow for escape of the most energetic atoms, resulting in cooling so that the Bose-Einstein Condensate is formed. Physics 2000 demands robust computing power. Check the system requirements on the introductory screen before venturing too far into this site. Martin V. Goldman, from the University of Colorado at Boulder, is the Director of Physics 2000, which received support from the Colorado Commission on Higher Education and the National Science Foundation. David Rea is the Technical Director, and many others help make this excellent site possible. Mark your calendars: October 31 through December 3, 1999!

  12. Decoding the codes: A content analysis of the news coverage of genetic cloning by three online news sites and three national daily newspapers, 1996 through 1998

    NASA Astrophysics Data System (ADS)

    Hyde, Jon E.

    This study compared news coverage of genetic cloning research in three online news sites (CNN.com, ABC.com, and MSNBC.com) and three national daily newspapers (The New York Times, The Washington Post, and USA Today). The study involved the analysis of 230 online and print news articles concerning genetic cloning published from 1996 through 1998. Articles were examined with respect to formats, sources, focus, tone, and assessments about the impact of cloning research. Findings indicated that while print news formats remained relatively constant for the duration of this study, online news formats changed significantly with respect to the kinds of media used to represent the news, the layouts used to represent cloning news, and the emphasis placed on audio-visual content. Online stories were as much as 20 to 70% shorter than print stories. More than 50% of the articles appearing online were composed by outside sources (wire services, guest columnists, etc.). By comparison, nearly 90% of the articles published by print newspapers were written "in-house" by science reporters. Online news sites cited fewer sources and cited a smaller variety of sources than the newspapers examined here. In both news outlets, however, the sources most frequently cited were those with vested interests in furthering cloning research. Both online and print news coverage of cloning tends to focus principally on the technical procedures and on the future benefits of cloning. More than 60% of the articles focused on the techniques and technologies of cloning. Less than 25% of the articles focused on social, ethical, or legal issues associated with cloning. Similarly, articles from all six sources (75%) tended to be both positive and future-oriented. Less than 5% of the total articles examined here had a strongly negative or critical tone. Moreover, both online and print news sources increasingly conveyed a strong sense of acceptance about the possibility of human cloning. Data from this study are among the first to indicate the ways in which online news outlets are transforming science news. Furthermore, this study reaffirms the need for a greater diversity of sources in assessing a broader spectrum of issues related to cloning.

  13. Changing news: re-adjusting science studies to online newspapers.

    Riesch, Hauke

    2011-11-01

    With the newspapers' recent move to online reporting, traditional norms and practices of news reporting have changed to accommodate the new realities of online news writing. In particular, online news is much more fluid and prone to change in content than the traditional hard-copy newspapers--online newspaper articles often change over the course of the following days or even weeks as they respond to criticisms and new information becoming available. This poses a problem for social scientists who analyse newspaper coverage of science, health and risk topics, because it is no longer clear who has read and written what version, and what impact they potentially had on the national debates on these topics. In this note I want to briefly flag up this problem through two recent examples of U.K. national science stories and discuss the potential implications for PUS media research. PMID:22397084

    2004-12-01

    Teachable Moments in the News (www.challenger.org/tmn/) is an online resource developed at Challenger Center for Space Science Education that takes recent news stories related to Solar System science and places them in a context relevant to the grades K-12 science curriculum. Using stories such as the launch of the MESSENGER spacecraft to Mercury, Teachable Moments in the News is meant to provide a seamless pathway from the news desk to the classroom. For each news item, an overview of the story is provided, along with high-quality inquiry-based, standards-driven lessons and links to more in-depth articles. Teachable Moments in the News is also a great tool for scientists who wish to stay informed of the recent events in Solar System exploration. The archived back issues of the quarterly published Web digest allow for a quick refresher on the most important news stories over the past several months. The very accessible nature of the stories makes the resource valuable for college students, and even the general public, as a means to keep up-to-date about current developments in planetary astronomy. Furthermore, college and university teachers can easily adapt many of the lessons to fit into the curriculum of an undergraduate astronomy course. During the poster session, we welcome suggestions from the scientific community on ways to enhance the usefulness of Teachable Moments in the News. For example, researchers could form partnerships with Teachable Moments in the News to provide news stories on their current research to be featured on the Web site. We invite researchers interested in this education and public outreach tool to visit the poster and provide suggestions on how to make the resource work as effectively as possible.

    Paper or plastic? I am asked this question every time I go grocery shopping. Asked another way, the question is, "Which polymer do you want?" To learn about polymers, go shopping at a great site from the University of Southern Mississippi, The Macrogalleria, a cyberwonderland of polymer fun at http://www.psrc.usm.edu/macrog/index.html . Plan to spend some time here. Bring along Chime and Shockwave plug-ins or download them from The Macrogalleria. The Macrogalleria shopping mall is divided into five levels. On the first level, Polymers are Everywhere at http:/ /www.psrc.usm.edu/macrog/floor1.html, you can visit stores selling sporting goods, food, and clothing. Learn about natural polymers in shoes and in French fries at http://www.psrc.usm.edu/macrog/natupoly.html . Find out about nylon in toothbrushes at http://www.psrc.usm.edu/macrog/nylon.html and about carbon fibers in tennis racquets at http://www.psrc.usm.edu/macrog /carfib.html-great graphics and even better chemistry. Skip up to level three for How They Work at http:/ /www.psrc.usm.edu/macrog/floor3.html. Take a look at the history of rubber on The Cross-linking Page at http:/ /www.psrc.usm.edu/macrog/xlink.html. Move on to level four for Makin' Polymers at http://www.psrc.usm.edu/macrog /floor4.html. Let's go right to the Ziegler-Natta Vinyl Polymerization at http://www.psrc.usm.edu/macrog/ziegler.html . Don't miss the humor in the initial explanation of the process. This page is excellent-with graphics, reactions, and a movie of a polymerization ( http://www.psrc.usm.edu/macrog/movies/zns.html ). This movie is worth seeing several times. Next take a look at another catalyst metallocene at http:/ /www.psrc.usm.edu/macrog/mcene.html. Explanations, graphics, and mechanisms help make this site worth visiting and great for teaching. Several people contributed to The Macrogalleria, with major contributions from Mark Michalovic of the University of Southern Mississippi. Grants were from POLYED, a joint committee of the American Chemical Society Divisions of Polymer Chemistry and Polymeric Materials: Science and Engineering and General Electric Corporation. The POLYED site, http:/ /chemdept.uwsp.edu/polyed/index.htm, is hosted by the University of Wisconsin at Stevens Point. This National Center for Polymer Education is another good place to go for information. More education is available at the Ziegler Research Group Home Page at http://www.chem.ucalgary.ca/groups/ziegler/index.html . Go to Metallocene as Olefin Polymerization Catalysis: An Introduction ( http://www.chem.ucalgary.ca/groups/ziegler/met_intro.html ) for historical accounts of metallocene and Ziegler-Natta catalysts. Movies are available here too. This Canadian site is well-documented and educational. Back at the University of Wisconsin-Madison, The Why Files site at http://whyfiles.news.wisc.edu helps bring important chemical and technology news to the public. Go to the archived files of October 1997 ( http://whyfiles.news.wisc.edu/shorties/catalyst.html ) to find information about the importance of low-temperature metallocene catalysts. The Why Files received funding from the National Science Foundation. Go here for science information in an easy-to-read format. One of the driving forces toward better catalysis is the attempt to reach 100% product, combining efficiency with lowered pollution. Companies can look to the Environmental Protection Agency for information: Environsense at http://es.epa.gov/ is pledged to offer "Common Sense Solutions to Environmental Problems". So where can we get these polymers? The American Chemical Society can help. Go to Chemcylopedia at http://pubs.acs.org/chemcy99/ for great information. Both purchasers and users of chemicals can benefit from this site. Searches can be made on the chemical or on the supplier. Information provided includes CAS Registry Numbers and special shipping requirements as well as potential applications. Do you remember that we started with paper? Let's end with information about making paper. Go to http://www.sci.fi /~saarives/pulpmfl.htm for Ahlstrom Machinery's Typical Offerings for Chemical Pulp Mills. Now this is a chemically rich plant that is worth the trip.

    Conservation science needs to engage the general public to ensure successful conservation interventions. Although online technologies such as Twitter and Facebook offer new opportunities to accelerate communication between conservation scientists and the online public, factors influencing the spread of conservation news in online media are not well understood. We explored transmission of conservation research through online news articles with generalized linear mixed-effects models and an information theoretic approach. In particular, we assessed differences in the frequency conservation research is featured on online news sites and the impact of online conservation news content and delivery on Facebook likes and shares and Twitter tweets. Five percent of articles in conservation journals are reported in online news, and the probability of reporting depended on the journal. There was weak evidence that articles on climate change and mammals were more likely to be featured. Online news articles about charismatic mammals with illustrations were more likely to be shared or liked on Facebook and Twitter, but the effect of news sites was much larger. These results suggest journals have the greatest impact on which conservation research is featured and that news site has the greatest impact on how popular an online article will be on Facebook and Twitter.

    Background The aim of this study was to understand online public perceptions of the debate surrounding the choice of annual influenza vaccinations or wearing masks as a condition of employment for healthcare workers, such as the one enacted in British Columbia in August 2012. Methods Four national and 82 local (British Columbia) Canadian online news sites were searched for articles posted between August 2012 and May 2013 containing the words “healthcare workers” and “mandatory influenza vaccinations/immunizations” or “mandatory flu shots and healthcare workers.” We included articles from sources that predominantly concerned our topic of interest and that generated reader comments. Two researchers coded the unedited comments using thematic analysis, categorizing codes to allow themes to emerge. In addition to themes, the comments were categorized by: 1) sentiment towards influenza vaccines; 2) support for mandatory vaccination policies; 3) citing of reference materials or statistics; 4) self-identified health-care worker status; and 5) sharing of a personal story. Results 1163 comments made by 648 commenters responding to 36 articles were analyzed. Popular themes included concerns about freedom of choice, vaccine effectiveness, patient safety, and distrust in government, public health, and the pharmaceutical industry. Almost half (48%) of commenters expressed a negative sentiment toward the influenza vaccine, 28% were positive, 20% were neutral, and 4% expressed mixed sentiment. Of those who commented on the policy, 75% did not support the condition to work policy, while 25% were in favour. Of the commenters, 11% self-identified as healthcare workers, 13% shared personal stories, and 18% cited a reference or statistic. Interpretation The perception of the influenza vaccine in the comment sections of online news sites is fairly poor. Public health agencies should consider including online forums, comment sections, and social media sites as part of their communication channels to correct misinformation regarding the benefits of HCW influenza immunization and the effectiveness of the vaccine.

    2015-01-01

    Because the volume of information available online is growing at breakneck speed, keeping up with meaning and information communicated by the media and netizens is a new challenge both for scholars and for companies who must address public relations crises. Most current theories and tools are directed at identifying one website or one piece of online news and do not attempt to develop a rapid understanding of all websites and all news covering one topic. This paper represents an effort to integrate statistics, word segmentation, complex networks and visualization to analyze headlines' keywords and words relationships in online Chinese news using two samples: the 2011 Bohai Bay oil spill and the 2010 Gulf of Mexico oil spill. We gathered all the news headlines concerning the two trending events in the search results from Baidu, the most popular Chinese search engine. We used Simple Chinese Word Segmentation to segment all the headlines into words and then took words as nodes and considered adjacent relations as edges to construct word networks both using the whole sample and at the monthly level. Finally, we develop an integrated mechanism to analyze the features of words' networks based on news headlines that can account for all the keywords in the news about a particular event and therefore track the evolution of news deeply and rapidly.

    Because the volume of information available online is growing at breakneck speed, keeping up with meaning and information communicated by the media and netizens is a new challenge both for scholars and for companies who must address public relations crises. Most current theories and tools are directed at identifying one website or one piece of online news and do not attempt to develop a rapid understanding of all websites and all news covering one topic. This paper represents an effort to integrate statistics, word segmentation, complex networks and visualization to analyze headlines’ keywords and words relationships in online Chinese news using two samples: the 2011 Bohai Bay oil spill and the 2010 Gulf of Mexico oil spill. We gathered all the news headlines concerning the two trending events in the search results from Baidu, the most popular Chinese search engine. We used Simple Chinese Word Segmentation to segment all the headlines into words and then took words as nodes and considered adjacent relations as edges to construct word networks both using the whole sample and at the monthly level. Finally, we develop an integrated mechanism to analyze the features of words’ networks based on news headlines that can account for all the keywords in the news about a particular event and therefore track the evolution of news deeply and rapidly.

    A stream of unstructured news can be a valuable source of hidden relations between different entities, such as financial institutions, countries, or persons. We present an approach to continuously collect online news, recognize relevant entities in them, and extract time-varying networks. The nodes of the network are the entities, and the links are their co-occurrences. We present a method to estimate the significance of co-occurrences, and a benchmark model against which their robustness is evaluated. The approach is applied to a large set of financial news, collected over a period of two years. The entities we consider are 50 countries which issue sovereign bonds, and which are insured by Credit Default Swaps (CDS) in turn. We compare the country co-occurrence networks to the CDS networks constructed from the correlations between the CDS. The results show relatively small, but significant overlap between the networks extracted from the news and those from the CDS correlations. PMID:25470498

    2012-01-01

    Purpose: The purpose of this study was to gain insight into public awareness of intimate partner violence (IPV) in late life by how individuals respond to incidents of IPV reported in the newspaper. Design and Methods: Using grounded theory techniques, online news items covering 24 incidents of IPV in late life, and the reader comments posted to them were analyzed. The news items were examined for incident details, story framing, and reporting style. An open coding process (Charmaz, K. [2006]. Constructing grounded theory: A practical guide through qualitative analysis. Thousand Oaks, CA: Sage Publications.) was used to generate a comprehensive understanding of themes and patterns in the comments posted by readers. Results: Few posters indicated that incidents were episodes of IPV. As many posters struggled to make sense of incidents, they attempted to remove guilt from the perpetrator by assigning blame elsewhere. Comments were influenced by personal assumptions and perspectives about IPV, relationships, and old age; reporting style of the news items; and comments posted by other posters. Implications: Altering public views of IPV in late life requires raising awareness through education, reframing the ways in which information is presented, and placing greater emphasis on the context of the violence. By engaging interactive news media, reporters, participatory journalists, and policymakers can enhance public recognition and understanding of IPV in late life. PMID:22547086

    Traditional commercial bibliographic databases and indexes provide some access to hydrology materials produced by the government; however, these sources do not provide comprehensive coverage of relevant hydrologic publications. This paper discusses bibliographic information available from the federal government and state geological surveys, water resources agencies, and depositories. In addition to information in these databases, the paper describes the scope, styles of citing, subject terminology, and the ways these information sources are currently being searched, formally and informally, by hydrologists. Information available from the federal and state agencies and from the state depositories might be missed by limiting searches to commercially distributed databases. ?? 2001 by The Haworth Press, Inc.

    Kononova, Anastasia G

    2013-05-01

    An experiment (N=123) examined how individuals cognitively process online news stories depicting African-American characters with stereotype-consistent and -inconsistent attributes and whether distracting online ads interfere with story processing. Two cognitive control functions, updating and inhibition, were predicted to moderate the effects of distracting ads. Recall of characters' attributes and overall characters' description were included in the study as dependent measures. Findings indicated that distracting online ads hinder recall of information about and descriptions of story characters. Inhibition and updating affect dependent measures and moderate the effects of distracting online ads on characters' descriptions. PMID:23574346

  10. Network news coverage of obesity in two time periods: an analysis of issues, sources, and frames.

    PubMed

    Gearhart, Sherice; Craig, Clay; Steed, Chaille

    2012-01-01

    Obesity is an epidemic plaguing American society. The current study adds to a growing body of framing research as it examines the portrayal of obesity on television network news in two 5-year time periods, 1995-1999 and 2005-2009. Through content analysis of TV news transcripts from three networks (ABC, NBC, and CBS), this study analyzed episodic-thematic frames, issues, and sources. Results revealed the amount of obesity-related news coverage increased along with thematically framed stories. The use of politicians, affected others, supporters, and others as sources increased, but experts and those struggling with obesity remained primary sources. Changes in the proportion of issues discussed revealed significant decreases in the discussion of genetic causes and personal stories. Results reflect the societal impact of obesity and indicate the ways in which obesity is perceived by the public through network news. Findings provide insight for media advocacy opportunities and contribute to research on framing and obesity. PMID:22236324

  12. Understanding Public Perceptions of the HPV Vaccination Based on Online Comments to Canadian News Articles

    Feinberg, Yael; Pereira, Jennifer A.; Quach, Susan; Kwong, Jeffrey C.; Crowcroft, Natasha S.; Wilson, Sarah E.; Guay, Maryse; Lei, Yang; Deeks, Shelley L.

    2015-01-01

    Background Given the variation in human papillomavirus (HPV) vaccine coverage across Canada, and debate regarding delivery of HPV vaccines in Catholic schools, we studied online comments on Canadian news websites to understand public perceptions of HPV and HPV vaccine. Methods We searched English- and French-language Canadian news websites for 2012 articles that contained the terms “HPV” or “human papillomavirus.” Articles about HPV vaccinations that contained at least one comment were included. Two researchers independently coded comments, analyzing them for emerging themes. Results We identified 3073 comments from 1198 individuals in response to 71 news articles; 630 (52.6%) individuals expressed positive sentiments about HPV vaccination (2.5 comments/individual), 404 (33.7%) were negative (3.0 comments/individual), 34 (2.8%) were mixed (1.5 comments/individual) and 130 (10.8%) were neutral (1.6 comments/individual). Vaccine-supportive commenters believed the vaccine is safe and effective. Common themes in negative comments included concerns regarding HPV vaccine safety and efficacy, distrust of pharmaceutical companies and government, and belief that school-age children are too young for HPV vaccine. Many comments focused on whether the Catholic Church has the right to inform health policy for students, and discussion often evolved into debates regarding HPV and sexual behaviour. We noted that many individuals doubted the credibility of vaccine safety information. Conclusion The majority of commenters do not appear to be against HPV vaccination, but public health messaging that focuses on both the vaccine’s safety profile, and its use as a means to prevent cancer rather than sexually transmitted HPV infection may facilitate its acceptance.

    2014-02-01

    Herbal products are commonly used to treat clinical conditions and are often purchased online without the supervision of a healthcare provider. The use of herbals remains controversial because of widespread exaggerated claims of clinical efficacy and safety. We conducted an online search of 13 common herbals (including black cohosh, echinacea, garlic, ginkgo, ginseng, green tea, kava, saw palmetto, and St John's wort) and reviewed the top 50 Web sites for each using a Google search. We analyzed clinical claims, warnings, and other safety information. A total of 1179 Web sites were examined. Less than 8% of retail sites provided information regarding potential adverse effects, drug interactions, and other safety information; only 10.5% recommended consultation with a healthcare professional. Less than 3% cited scientific literature to accompany their claims. Key safety information is still lacking from many online sources of herbal information. Certain nonretail site types may be more reliable, but physicians and other healthcare professionals should be aware of the variable quality of these sites to help patients make more informed decisions.

    2012-01-01

    This study analyzes the issue attention cycle for print and online media coverage of a scientific publication examining the deaths of Chinese factory workers due to lung damage from chronic exposure to nanoparticles. The results of the nanoparticle study, published in 2009, embody news values that would make the study a prime candidate for press coverage, namely, novelty, negativity, controversy, and potential widespread impact. Nevertheless, mentions of the event in traditional English-language print media were nearly nonexistent. Online media, on the other hand, gave the story greater coverage. This case study exemplifies why online media may not be bound to the same issue attention cycle that print media are for controversial scientific events. PMID:23379318

  19. Earned Media and Public Engagement With CDC’s "Tips From Former Smokers" Campaign: An Analysis of Online News and Blog Coverage

    PubMed Central

    Kornfield, Rachel; Szczypka, Glen; Vera, Lisa; Emery, Sherry

    2015-01-01

    Background In March 2012, the US Centers for Disease Control and Prevention (CDC) launched the first-ever paid national tobacco education campaign. At a cost of US $54 million, “Tips from Former Smokers” (Tips) ran for 3 months across multiple media, depicting the suffering experienced by smokers and their families in graphic detail. The potential impact and reach of the Tips campaign was not limited to that achieved through paid media placements. It was also potentially extended through “earned media”, including news and blog coverage of the campaign. Such coverage can shape public understanding of and facilitate public engagement with key health issues. Objective To better understand the contribution of earned media to the public’s engagement with health issues in the current news media environment, we examined the online “earned media” and public engagement generated by one national public health campaign. Methods We constructed a purposive sample of online media coverage of the CDC’s 2012 Tips from Former Smokers television campaign, focusing on 14 influential and politically diverse US news outlets and policy-focused blogs. We identified relevant content by combining campaign and website-specific keywords for 4 months around the campaign release. Each story was coded for content, inclusion of multimedia, and measures of audience engagement. Results The search yielded 36 stories mentioning Tips, of which 27 were focused on the campaign. Story content between pieces was strikingly similar, with most stories highlighting the same points about the campaign’s content, cost, and potential impact. We saw notable evidence of audience engagement; stories focused on Tips generated 9547 comments, 8891 Facebook “likes”, 1027 tweets, and 505 story URL shares on Facebook. Audience engagement varied by story and site, as did the valence and relevance of associated audience comments. Comments were most oppositional on CNN and most supportive on Yahoo. Comment coding revealed approximately equal levels of opposition and support overall. We identified four common arguments among oppositional comments: government intrusion on personal behaviors, problematic allocation of governmental spending, questionable science, and challenges regarding campaign efficacy. Supportive comments tended to convey personal stories and emotions. Conclusions The Tips campaign received limited coverage on either online news or blog sources, but the limited number of stories generated engagement among online audiences. In addition to the content and volume of blog and news coverage, audience comments and websites’ mechanisms for sharing stories via social media are likely to determine the influence of online earned media. In order to facilitate meaningful evaluation of public health campaigns within the rapidly advancing media environment, there is a need for the public health community to build consensus regarding collection and assessment of engagement data.

    2016-01-01

    With the continuous growth of internet usage, Google Trends has emerged as a source of information to investigate how social trends evolve over time. Knowing how the level of interest in conservation topics-approximated using Google search volume-varies over time can help support targeted conservation science communication. However, the evolution of search volume over time and the mechanisms that drive peaks in searches are poorly understood. We conducted time series analyses on Google search data from 2004 to 2013 to investigate: (i) whether interests in selected conservation topics have declined and (ii) the effect of news reporting and academic publishing on search volume. Although trends were sensitive to the term used as benchmark, we did not find that public interest towards conservation topics such as climate change, ecosystem services, deforestation, orangutan, invasive species and habitat loss was declining. We found, however, a robust downward trend for endangered species and an upward trend for ecosystem services. The quantity of news articles was related to patterns in Google search volume, whereas the number of research articles was not a good predictor but lagged behind Google search volume, indicating the role of news in the transfer of conservation science to the public.

The quantity of news articles was related to patterns in Google search volume, whereas the number of research articles was not a good predictor but lagged behind Google search volume, indicating the role of news in the transfer of conservation science to the public.

    Mastroianni, Anna; Kahn, Jeffrey

    2012-01-01

    Health-related research is increasingly drawing on novel sources of online data, such as crowdsourced information about disease outbreaks, consumer-supplied information provided to health or wellness Web sites, Internet search queries about personal health, and social network postings that identify health behaviors. We offer examples of online sources and their uses, identify ethical and policy issues they generate, and formulate key questions for future discussion and investigation. Further work in this area will require cross-disciplinary collaboration to develop ethics and policy guidance for the ethical use of these novel data sources in health-related research.

    2005-03-01

    While most research on information access focuses on search engines, a significant fraction of new information we are exposed to comes from news, whose source is increasingly shifting online. News, however, have a fleeting quality: in contrast with the 24-hour news cycle of the printed press, in the online and audiovisual media the non-stop stream of new developments often obliterates a news event within hours. Through archives, the Internet offers better long-term search-based access to old events than any other media before. Yet, if we are not exposed to a news item while prominently featured, it is unlikely that we will know what to search for. The accelerating news cycle raises several important questions: How long is a piece of news accessible without targeted search? What is the dynamics of news accessibility?

  12. Testing the effect of framing and sourcing in health news stories.

    PubMed

    Coleman, Renita; Thorson, Esther; Wilkins, Lee

    2011-10-01

    This study examines whether changing the way news stories report on health can induce shifts in readers' perceptions of problems of obesity, diabetes, immigrant health, and smoking. The authors manipulated two variables in a controlled experiment: the quality of sourcing-the number of sources and their expertise-and the framing-changing from an episodic, traditional frame to a thematic frame that incorporated information on context, risk factors, prevention strategies, and social attributions of responsibility. The authors found that a thematic frame made readers more supportive of public policy changes and encouraged them to improve their own health behaviors. However, it did not alter their attributions of responsibility for health problems from one of blaming individuals to seeing the larger social factors. Adding richer sourcing to the thematic frame did not increase these effects, nor did readers find the thematic stories to be more interesting, relevant, believable, important, and informative. In addition, there were differential results because of story topics that represent uncontrolled effects. The implications for improving health reporting to encourage positive change in society are discussed. PMID:21660828

    Information technology has brought about changes in the work patterns of researchers and scientists. After some hints on the on-line facilities needed to be connected to the international host computers, an analysis is made of some of the main automated sources available to retrieve information on chemical substances. Special emphasis is given to textual-numeric data banks, first reviewing the main chemical dictionaries, like Registry and Chemline, and then focusing on those sources that offer immediate information in case of emergency. Among the Toxnet files, produced and managed within the US National Library of Medicine Toxicology Information Program, play a very important role in offering publicly available data on toxicology and on hazardous chemicals. Therefore, the Hazardous Substances Data Bank (HSDB) and the Registry of Toxic Effects of Chemical Substances (RTECS) are described for their relevance thereon. Other data banks produced in Europe, like the Environmental Chemicals Data Information Network (ECDIN) and the very specialized Major Hazard Incident Data Service (MHIDAS) are also briefly outlined. To integrate this overview on online information, the attention is then shifted on sources having the characteristic of reference databases: prestigious files covering the international scientific literature, as CA/Chemabs, Toxline/Toxlit, Embase, Medline are introduced. Implications of on-line technology in enhancing information access in the next future are discussed, pointing out the new tools created to meet the information needs of end-users. PMID:7762934

    Prothero, W. A.

    2003-12-01

    The purpose of the EarthEd Online software project is to support a modern instructional pedagogy in a large, college level, earth science course. It is an ongoing development project that has evolved in a large general education oceanography course over the last decade. Primary goals for the oceanography course are to support learners in acquiring a knowledge of science process, an appreciation for the relevance of science to society, and basic content knowledge. In order to support these goals, EarthEd incorporates: a) integrated access to various kinds of real earth data (and links to web-based data browsers), b) online discussions, live chat, with integrated graphics editing, linking, and upload, c) online writing, reviewing, and grading, d) online homework assignments, e) on demand grade calculation, and f) instructor grade entry and progress reports. The software was created using Macromedia Director. It is distributed to students on a CDROM and updates are downloaded and installed automatically. Data browsers for plate tectonics relevant data ("Our Dynamic Planet"), a virtual exploration of the East Pacific Rise, the World Ocean Atlas-98, and a fishing simulation game are integrated with the EarthEd software. The system is modular which allows new capabilities, such as new data browsers, to be added. Student reactions to the software are positive overall. They are especially appreciative of the on demand grade computation capability. The online writing, commenting and grading is particularly effective in managing the large number of papers that get submitted. The TA's grade the papers, but the instructor can provide feedback to them as they grade the papers, and a record is maintained of all comments and rubric item grades. Commenting is made easy by simply "dragging" a selection of pre-defined comments into the student's text. Scoring is supported by an integrated scoring rubric. All assignments, rubrics, etc. are configured in text files that are downloaded from the course web server. Students rate the writing assignments as the most effective learning activity in the course. This project is in an evaluation and dissemination phase. An open source model is planned for distribution. For documentation and information about the EarthEd team, see: http://oceanography.geol.ucsb.edu/Collab/software.html

    2014-01-01

    Objective to describe the coverage of news concerning the nursing profession in the Portuguese media: informative sites on the Internet and in print media. Method a total of 1,271 health news items were collected in September and October of 2011 (956 online news items and 325 news items originating from the press review of the Portuguese Order of Nurses). Statistical analysis was used to characterize the variables. Results nurses were the sources of information in 6.6% of cases, suggesting limited media exposure. The health news collected is characterized by a production based on limited information sources, that is, male and official sources, on information disseminated by news agencies focused on economic and political issues in the health field. Conclusion the presence of nurses in the news concerning nursing health is reduced. We suggest that nurses develop public communication skills to disseminate the importance of their profession in society and their relationship with the media. PMID:24553715

    2015-07-01

    Individual spreading behavior in online social networks is closely related to user activity, tie strength, and other user and network features. The results concentrate on personal spreading decisions; however, whether these features promote the global information diffusion and increase the macroscopic density of infected agents, remains unclear to us. In this paper, we propose a multi-source diffusion model in which agents may create new messages and spread other agents’ messages. Agents receive many messages, and each time they select a certain message preferentially to spread in consideration of different features. Simulation results show the density of infected agents for different messages follows a power-law distribution in both scale-free and small-world networks. Selecting the largest author degree, author activity and tie strength preferentially can advance the overall diffusion process. Weak tie bias is the least effective feature for multiple information diffusion, but it helps to diffuse a single message. Unexpectedly, the bias of interest similarity does not have an apparent effect. Integrated with the influence on individual diffusion behavior, strong tie bias is a significant feature both for local and global diffusion.

    Objectives Estimate the proportion of dental practitioners who use online sources of information for practice guidance. Methods From a survey of 657 dental practitioners in The Dental Practice Based Research Network, four indicators of online use for practice guidance were calculated: read journals online, obtained continuing education (CDE) through online sources, rated an online source as most influential, and reported frequently using an online source for guidance. Demographics, journals read, and use of various sources of information for practice guidance in terms of frequency and influence were ascertained for each. Results Overall, 21% (n=138) were classified into one of the four indicators of online use: 14% (n=89) rated an online source as most influential and 13% (n=87) reported frequently using an online source for guidance; few practitioners (5%, n=34) read journals online, fewer (3%, n=17) obtained CDE through online sources. Use of online information sources varied considerably by region and practice characteristics. In general, the 4 indicators represented practitioners with as many differences as similarities to each other and to offline users. Conclusion A relatively small proportion of dental practitioners use information from online sources for practice guidance. Variation exists regarding practitioners’ use of online source resources and how they rate the value of offline information sources for practice guidance. PMID:22994848

    Feminist news media researchers have long contended that masculine news values shape journalists' quotidian decisions about what is newsworthy. As a result, it is argued, topics and issues traditionally regarded as primarily of interest and relevance to women are routinely marginalised in the news, while men's views and voices are given privileged space. When women do show up in the news, it is often as "eye candy," thus reinforcing women's value as sources of visual pleasure rather than residing in the content of their views. To date, evidence to support such claims has tended to be based on small-scale, manual analyses of news content. In this article, we report on findings from our large-scale, data-driven study of gender representation in online English language news media. We analysed both words and images so as to give a broader picture of how gender is represented in online news. The corpus of news content examined consists of 2,353,652 articles collected over a period of six months from more than 950 different news outlets. From this initial dataset, we extracted 2,171,239 references to named persons and 1,376,824 images resolving the gender of names and faces using automated computational methods. We found that males were represented more often than females in both images and text, but in proportions that changed across topics, news outlets and mode. Moreover, the proportion of females was consistently higher in images than in text, for virtually all topics and news outlets; women were more likely to be represented visually than they were mentioned as a news actor or source. Our large-scale, data-driven analysis offers important empirical evidence of macroscopic patterns in news content concerning the way men and women are represented. PMID:26840432

  12. Online blind source separation using incremental nonnegative matrix factorization with volume constraint.

    2011-04-01

    Online blind source separation (BSS) is proposed to overcome the high computational cost problem, which limits the practical applications of traditional batch BSS algorithms. However, the existing online BSS methods are mainly used to separate independent or uncorrelated sources. Recently, nonnegative matrix factorization (NMF) shows great potential to separate the correlative sources, where some constraints are often imposed to overcome the non-uniqueness of the factorization. In this paper, an incremental NMF with volume constraint is derived and utilized for solving online BSS. The volume constraint to the mixing matrix enhances the identifiability of the sources, while the incremental learning mode reduces the computational cost. The proposed method takes advantage of the natural gradient based multiplication updating rule, and it performs especially well in the recovery of dependent sources. Simulations in BSS for dual-energy X-ray images, online encrypted speech signals, and high correlative face images show the validity of the proposed method. PMID:21382767

    2012-01-01

    Online news sources produce thousands of news articles every day, reporting on local and global real-world events. New information quickly replaces the old, making it difficult for readers to put current events in the context of the past. Additionally, the stories have very complex relationships and characteristics that are difficult to model: they can be weakly or strongly connected, or they can merge or split over time. In this paper, we present a visual analytics system for exploration of news topics in dynamic information streams, which combines interactive visualization and text mining techniques to facilitate the analysis of similar topics that split and merge over time. We employ text clustering techniques to automatically extract stories from online news streams and present a visualization that: 1) shows temporal characteristics of stories in different time frames with different level of detail; 2) allows incremental updates of the display without recalculating the visual features of the past data; 3) sorts the stories by minimizing clutter and overlap from edge crossings. By using interaction, stories can be filtered based on their duration and characteristics in order to be explored in full detail with details on demand. To demonstrate the usefulness of our system, case studies with real news data are presented and show the capabilities for detailed dynamic text stream exploration.

    An overview of the first spatially explicit, multielement (N, P, and C), multiform (dissolved inorganic: DIN, DIP; dissolved organic: DOC, DON, DOP; and particulate: POC, PN, PP) predictive model system of river nutrient export from watersheds (Global Nutrient Export from Watersheds (NEWS)) is presented. NEWS models estimate export from 5761 watersheds globally as a function of land use, nutrient inputs, hydrology, and other factors; regional and global scale patterns as of 1995 are presented here. Watershed sources and their relative magnitudes differ by element and form. For example, anthropogenic sources dominate the export of DIN and DIP at the global scale, although their anthropogenic sources differ significantly (diffuse and point, respectively). Natural sources dominate DON and DOP export globally, although diffuse anthropogenic sources dominate in several regions in Asia, Europe and N. America. "Hot spots" where yield (kg km-2 yr-1) is high for several elements and forms were identified, including parts of Indonesia, Japan, southern Asia, and Central America, due to anthropogenic N and P inputs in some regions and high water runoff in others. NEWS models provide a tool to examine past, current and future river export of nutrients, and how humans might impact element ratios and forms, and thereby affect estuaries and coastal seas.

    2015-01-01

    Rationale and Objectives Millions of people use online search engines every day to find health-related information and voluntarily share their personal health status and behaviors in various Web sites. Thus, data from tracking of online information seeker’s behavior offer potential opportunities for use in public health surveillance and research. Google Trends is a feature of Google which allows internet users to graph the frequency of searches for a single term or phrase over time or by geographic region. We used Google Trends to describe patterns of information seeking behavior in the subject of dense breasts and to examine their correlation with the passage or introduction of dense breast notification legislation. Materials and Methods In order to capture the temporal variations of information seeking about dense breasts, the web search query “dense breast” was entered in the Google Trends tool. We then mapped the dates of legislative actions regarding dense breasts that received widespread coverage in the lay media to information seeking trends about dense breasts over time. Results Newsworthy events and legislative actions appear to correlate well with peaks in search volume of “dense breast”. Geographic regions with the highest search volumes have either passed, denied, or are currently considering the dense breast legislation. Conclusions Our study demonstrated that any legislative action and respective news coverage correlate with increase in information seeking for “dense breast” on Google, suggesting that Google Trends has the potential to serve as a data source for policy-relevant research.

SRCMOD collects and disseminates source models of past earthquakes. SIV aims at benchmarking the current state-of-the-art in earthquake source inversions and developing robust approaches to quantify uncertainties in the source models. CERS currently has three software packages. These include 'RupGen' for generating synthetic earthquake rupture models, 'Stress2Slip' for computing on-fault static stress changes corresponding to a slip distribution, and 'BB-Simulation' for computing and integrating high frequency synthetics with low frequency waveforms to generate hybrid broadband seismograms. We envision that this online platform will be useful in advancing research on earthquake source processes and earthquake engineering.

    News from Journal House

    Guidelines for Submission The Journal's current Guide to Submissions can be found on pages 29-30 of this issue. They have been streamlined a bit and also include a handy check list. This information is also available on JCE Online at http://jchemed.chem.wisc.edu/Journal/Authors/. Wanted: Demo Checkers The Tested Demonstrations column needs people who like to try out demos. Column editor Ed Vitz is looking for additional volunteers to serve as "checkers" for manuscripts that have been submitted to the Journal for possible publication as Tested Demonstrations. A checker is expected to perform two functions: to review the manuscript for accuracy and novelty, and to attempt to perform the demonstration according to the procedure supplied by the author. Checkers may suggest important improvements in demonstration procedures, and for their efforts they are cited in the byline when the manuscript is published. For instance, the demo showing the yellow cascading precipitates (lead iodide) made from potassium iodide and lead nitrate was submitted by Wobbe de Vos and checked by Kim Kostka. The (yellow) cascading precipitates are from "Using Large Glass Cylinders To Demonstrate Chemical Reactions" that appeared in the April 1999 issue of JCE. We prefer that checkers begin the review process (which may in some cases involve procuring supplies) very soon after being contacted so that their review can be completed in the timely manner that authors deserve. Checkers are usually teachers who routinely present lecture demonstrations in their classes in either high school or colleges. We try not to call on checkers more often than once a year, which is one of the reasons for this request. Another is that we lose many highly valued, experienced checkers to retirement or other endeavors. Prospective checkers may want to look at a copy of the JCE Tested Demonstration Evaluation Form. It can be found on the Web at http://www.kutztown.edu/ vitz/TD/TDhome.html. This site also has links to JCE guidelines for prospective authors. Volunteers should contact Vitz by the medium of their preference: Ed Vitz, Editor, Tested Demonstrations, Journal of Chemical Education, Department of Chemistry, Kutztown University, Kutztown, PA 19530; phone: 610/683-4443; fax: 610/683-1352; email: vitz@kutztown.edu.

  4. Thinking about online sources: Exploring students' epistemic cognition in internet-based chemistry learning

    NASA Astrophysics Data System (ADS)

    Dai, Ting

    This dissertation investigated the relation between epistemic cognition---epistemic aims and source beliefs---and learning outcome in an Internet--based research context. Based on a framework of epistemic cognition (Chinn, Buckland, & Samarapungavan, 2011), a context--specific epistemic aims and source beliefs questionnaire (CEASBQ) was developed and administered to 354 students from college--level introductory chemistry courses. A series of multitrait--multimethod model comparisons provided evidence for construct convergent and discriminant validity for three epistemic aims--- true beliefs, justified beliefs, explanatory connection, which were all distinguished from, yet correlated with, mastery goals. Students' epistemic aims were specific to the chemistry topics in research. Multidimensional scaling results indicated that students' source evaluation was based on two dimensions--- professional expertise and first--hand knowledge, suggesting a multidimensional structure of source beliefs. Most importantly, online learning outcome was found to be significantly associated with two epistemic aims---justified beliefs and explanatory connection: The more students sought justifications in the online research, the lower they tended to score on the learning outcome measure, whereas the more students sought explanatory connections between information, the higher they scored on the outcome measure. There was a significant but small positive association between source beliefs and learning outcome. The influences of epistemic aims and source beliefs on learning outcome were found to be above and beyond the effects of a number of covariates, including prior knowledge and perceived ability with online sources.

    2007-09-01

    A critical analysis of the canonical correlation analysis (CCA) approach in blind source separation (BSS) is provided. It is proved that by maximizing the autocorrelation functions of the recovered signals we can separate the source signals successfully. It is further shown that the CCA approach represents the same class of generalized eigenvalue decomposition (GEVD) problems as the matrix pencil method. Finally, online realizations of the CCA approach are discussed with a linear-predictor-based algorithm studied as an example. PMID:18220197

  15. Real-Time Adaptive EEG Source Separation Using Online Recursive Independent Component Analysis.

    PubMed

    Hsu, Sheng-Hsiou; Mullen, Tim R; Jung, Tzyy-Ping; Cauwenberghs, Gert

    2016-03-01

    Independent component analysis (ICA) has been widely applied to electroencephalographic (EEG) biosignal processing and brain-computer interfaces. The practical use of ICA, however, is limited by its computational complexity, data requirements for convergence, and assumption of data stationarity, especially for high-density data. Here we study and validate an optimized online recursive ICA algorithm (ORICA) with online recursive least squares (RLS) whitening for blind source separation of high-density EEG data, which offers instantaneous incremental convergence upon presentation of new data. Empirical results of this study demonstrate the algorithm's: 1) suitability for accurate and efficient source identification in high-density (64-channel) realistically-simulated EEG data; 2) capability to detect and adapt to nonstationarity in 64-ch simulated EEG data; and 3) utility for rapidly extracting principal brain and artifact sources in real 61-channel EEG data recorded by a dry and wearable EEG system in a cognitive experiment. ORICA was implemented as functions in BCILAB and EEGLAB and was integrated in an open-source Real-time EEG Source-mapping Toolbox (REST), supporting applications in ICA-based online artifact rejection, feature extraction for real-time biosignal monitoring in clinical environments, and adaptable classifications in brain-computer interfaces.

    Mlekodaj, Ronald L.

    1979-01-01

    A reduced size ion source for on-line use with a cyclotron heavy-ion beam is provided. A sixfold reduction in source volume while operating with similar input power levels results in a 2000.degree. C. operating temperature. A combined target/window normally provides the reaction products for ionization while isolating the ion source plasma from the cyclotron beam line vacuum. A graphite felt catcher stops the recoiling reaction products and releases them into the plasma through diffusion and evaporation. Other target arrangements are also possible. A twenty-four hour lifetime of unattended operation is achieved, and a wider range of elements can be studied than was heretofore possible.

    News from Journal House Perspective on JCE Online Recently a reader asked us for a perspective on JCE Onlinehow the chemical education community is receiving it and how the Journal staff itself views it. We share our responses below. Subscriber Numbers How many people subscribe to JCE Online+? As of June 1, 1999, our records show that 13% of individual JCE subscriptions in the USA include JCE Online+. This percentage has increased significantly during the past year- in June 1998 it was approximately 4% and December 1998 about 7%. Almost all subscribers to JCE Online subscribe to print as well. Since JCE Online has only very recently been made available to institutional subscribers, there are no numbers to report. There has been considerable interest in online from libraries. Given that JCE Online+ is a fairly recent subscriber option and that many subscribers have a wait-and-see approach to any new option, we feel that the numbers above are quite high. The steady growth is encouraging. Online Usage How many people visit our Web site? Statistics for the period January 1, 1999, through May 31, 1999, that may be of interest include:

    Total Pages Served 361,115

    Total Visits 138,377

    Total Unique Visitors 51,744

    Total Repeat Visitors 11,536

    Average Visit Length 03:05

    Average Requests/Visit 10.8

    Average Pages/Visit 2.6

    Average Daily Visits 916 Online Rationale and Expectations JCE Online is a very important part of the whole Journal, but we do not expect it to supplant print: online and print are very different media. Usage of JCE Online is growing steadily; our subscribers are realizing what we have learned: it is not possible to deliver the Journal in the print medium alone- print is no longer adequate to accomplish our mission. Examples of things not possible in print include:

    ·JCE Index to all 76 years of Journal issues, available all the time with responses within seconds.

    ·Supplementary materials that are important to only a limited number of our subscribers; materials that augment laboratory experiments are a good example.

    ·Supplementary videos, such as the videos, still images, and excerpts from interviews with nuclear chemists that give fuller meaning to the Viewpoints article "Chemistry of the Heaviest Elements- One Atom at a Time" referred to below.

    ·Internet feature columns are more effective in a dynamic medium. Two that are in place are Mathcad in the Chemistry Curriculum (edited by Theresa Zielinski) and Conceptual Questions and Challenge Problems (edited by William Robinson and Susan Nurrenbern).

    ·Buyers Guides have their content updated often and link to other useful sites. There is one for books and software and another for supplies and equipment. Elements Added to Periodic Table Two new transuranic elements have been added to the list in the Viewpoints article "Chemistry of the Heaviest ElementsOne Atom at a Time" by Darleane C. Hoffman and Diana M. Lee (JCE, 1999, 76, 331). The new elements have atomic numbers 118 and 116. The path to the discovery of these elements was predicted by Robert Smolanczuk, a young Polish theorist whose calculations led him to conclude that a lead-krypton collision technique could produce element 118, which then decays to element 116. Others questioned his results, but Hoffman invited him to join the team at the Lawrence Berkeley National Laboratory and a decision was made to try out his ideas. The result was almost complete verification of Smolanczuk's calculations. The experimental team was headed by Kenneth E. Gregorich; Darleane Hoffman is one of 15 codiscoverers of element 118. Awards Willard Gibbs Medal Lawrence F. Dahl of the University of Wisconsin-Madison is the recipient of 1999 Willard Gibbs Medal, the highest award of the Chicago Section of the American Chemical Society. It is awarded annually to a world-renowned scientist selected by a jury of panelists composed of eminent chemists elected by the Board of Directors of the Chicago Section. The award was presented at the Chicago Section's meeting in May 1999. Courses, Seminars, Meetings, Opportunities Grant Program for Senior Scientist Mentors The Camille and Henry Dreyfus Foundation announces a new initiative within its Special Grant Program in the Chemical Sciences: the Senior Scientist Mentors. Undergraduate participation in research is generally acknowledged to be one of the most effective ways for students to learn and appreciate chemistry. Key to a meaningful research experience is the advising and counseling a student can receive from leaders in chemical research. Application Details Emeritus faculty who maintain active research programs in the chemical sciences may apply for one of a limited number of awards that will allow undergraduates to do research under their guidance. Successful applicants, who are expected to be closely engaged in a mentoring relationship with the students, will receive grants of 10,000 annually for two years (20,000 total) for undergraduate stipends and modest research support. In approximately three pages, applicants should describe their ongoing research and the nature of the participation by undergraduates in the research activity. The role of the applicant as mentor should be clearly outlined. The application should also contain a curriculum vitae of no more than five pages that includes representative publications; a letter of support from the department chair that also commits appropriate space and facilities for the undergraduate participants; and a letter of support from a colleague (preferably from outside the department) who is familiar with the applicant's research and teaching. This initiative is open to all institutions that offer bachelor's or higher degrees in the chemical sciences. Use the standard cover page for the Special Grant Program in the Chemical Sciences, which is available at www.dreyfus.org. "Senior Scientist Mentors" should be entered as the project title. An original and five copies of the application are required. Applications should be received in the Foundation office (555 Madison Avenue, Suite 1305, New York, NY 10022) by September 1, 1999; awards will be announced toward the end of January 2000.

    2010-01-01

    The shift toward online communication in all realms, from print newspapers to broadcast television, has implications for how the general public consumes information about nanotechnology. The goal of this study is threefold: to investigate who is using online sources for information and news about science and nanotechnology, to examine what the general public is searching for online with regards to nanotechnology, and to analyze what they find in online content of nanotechnology. Using survey data, we find those who report the Internet as their primary source of science and technology news are diverse in age, more knowledgeable about science and nanotechnology, highly educated, male, and more diverse racially than users of other media. In a comparison of demographic data on actual visits by online users to general news and science Web sites, science sites attracted more male, non-white users from the Western region of the United States than news sites did. News sites, on the other hand, attracted those with a slightly higher level of education. Our analysis of published estimates of keyword searches on nanotechnology reveals people are turning to the Internet to search for keyword searches related to the future, health, and applications of nanotechnology. A content analysis of online content reveals health content dominates overall. Comparisons of content in different types of sites—blogs, government, and general sites—are conducted.

  6. The Changing Landscape of Science News

    NASA Astrophysics Data System (ADS)

    Riordon, James

    2011-03-01

    Social media are revolutionizing the ways that people communicate and the ways they get their news. Traditional news outlets are in decline, and no subject area is declining faster than science news. Every day there are fewer professional science journalists working in traditional media. On the other hand, ever greater numbers of scientists, science enthusiasts, and online journalists are turning to blogs, podcasts, eBooks, twitter feeds, and social media sites like Facebook and Tumbler to spread news about science. I will present an overview of the state of science journalism and speculate on the likely directions it seems to be heading. I will also offer some general guidelines to help scientists understand what makes a good science news story, as well as suggesting ways that they can get their work in the news.

  7. A news media analysis of economic sanction effects on access to medicine in Iran

    PubMed Central

    Kheirandish, Mehrnaz; Rashidian, Arash; Bigdeli, Maryam

    2015-01-01

    Objective: In the past decades economic sanctions have been used by different countries or international organizations in order to deprive target countries of some transactions. While the sanctions do not target health care systems or public health structures, they may, in fact, affect the availability of health care in target countries. In this study, we used media analysis to assess the impacts of recent sanctions imposed by the Central Bank of Iran in 2012 on access to medicines in Iran. Methods: We searched different sources of written news media including a database of nonspecialized weeklies and magazines, online news sources, web pages of daily newspapers and healthcare oriented weeklies from 2011 to 2013. We searched the sources using the general term “medicine” to reduce the chances of missing relevant items. The identified news media were read, and categorized under three groups of items announcing “shortage of medicines,” “medicines related issues” and “no shortage.” We conducted trend analyzes to see whether the news media related to access to medicines were affected by the economic sanctions. Findings: A total number of 371 relevant news media were collected. The number of news media related to medicines substantially increased in the study period: 30 (8%), 161 (43%) and 180 (49%) were published in 2011, 2012 and 2013, respectively. While 145 (39%) of media items referred to the shortage of medicines, 97 (26%) reported no shortage or alleviating of concerns. Conclusion: Media analysis suggests a clear increase in the number of news media reporting a shortage in Iran after the sanctions. In 2013, there were accompanying increases in the number of news media reporting alleviation of the shortages of medicines. Our analysis provides evidence of negative effects of the sanctions on access to medicines in Iran. PMID:26645026

  8. On-line thermal power estimation for control and protection of the advanced neutron source reactor

    1990-01-01

    This paper presents an evaluation of several techniques to provide on-line estimation of the thermal power for the advanced neutron source (ANS) reactor. This estimate will be used to convert neutron flux sensor measurements to power units before they are fed into the control and plant protection system. The approach proposed for the ANS thermal power monitor is based on the one used successfully at the High-Flux Isotope Reactor (HFIR), but with modifications to improve its time response and accuracy. The ANS reactor is designed primarily to serve as a source of thermal and very low energy neutrons for scattering experiments.

    2015-01-01

    Objectives Most research examining the impact of patients seeking online health information treats internet information homogenously, rather than recognizing that there are multiple types and sources of available information. The present research was conducted to differentiate among sources and types of internet information that patients search for, intend to discuss with their doctors, and recall discussing with their doctors, and to determine how accurate and hopeful patients rate this information. Methods We surveyed 70 breast cancer patients recruited from the waiting rooms of breast medical oncology and surgery clinics. The main variables in the study were as follows: (1) the sources and types of online information patients have read, intended to discuss, and actually discussed with their doctors, and (2) how accurately and hopefully they rated this information to be. Results Patients read information most frequently from the websites of cancer organizations, and most often about side effects. Patients planned to discuss fewer types of information with their doctors than they had read about. They most often intended to discuss information from cancer organization websites or WebMD, and the material was most often about alternative therapies, side effects, and proven or traditional treatments. Some 76.8% of total participants rated the information they had read as very or somewhat accurate, and 61% rated the information they had read as very or somewhat hopeful. Significance of Results Internet information varies widely by source and type. Differentiating among sources and types of information is essential to explore the ways in which online health information impacts patients’ experiences. PMID:24182945

  11. Sources of Information and Behavioral Patterns in Online Health Forums: Observational Study

    PubMed Central

    Friede, Tim; Grabowski, Jens; Koschack, Janka; Makedonski, Philip; Himmel, Wolfgang

    2014-01-01

    Background Increasing numbers of patients are raising their voice in online forums. This shift is welcome as an act of patient autonomy, reflected in the term “expert patient”. At the same time, there is considerable concern that patients can be easily misguided by pseudoscientific research and debate. Little is known about the sources of information used in health-related online forums, how users apply this information, and how they behave in such forums. Objective The intent of the study was to identify (1) the sources of information used in online health-related forums, and (2) the roles and behavior of active forum visitors in introducing and disseminating this information. Methods This observational study used the largest German multiple sclerosis (MS) online forum as a database, analyzing the user debate about the recently proposed and controversial Chronic Cerebrospinal Venous Insufficiency (CCSVI) hypothesis. After extracting all posts and then filtering relevant CCSVI posts between 01 January 2008 and 17 August 2012, we first identified hyperlinks to scientific publications and other information sources used or referenced in the posts. Employing k-means clustering, we then analyzed the users’ preference for sources of information and their general posting habits. Results Of 139,912 posts from 11,997 threads, 8628 posts discussed or at least mentioned CCSVI. We detected hyperlinks pointing to CCSVI-related scientific publications in 31 posts. In contrast, 2829 different URLs were posted to the forum, most frequently referring to social media, such as YouTube or Facebook. We identified a total of 6 different roles of hyperlink posters including Social Media Fans, Organization Followers, and Balanced Source Users. Apart from the large and nonspecific residual category of the “average user”, several specific behavior patterns were identified, such as the small but relevant groups of CCSVI-Focused Responders or CCSVI Activators. Conclusions The bulk of the observed contributions were not based on scientific results, but on various social media sources. These sources seem to contain mostly opinions and personal experience. A small group of people with distinct behavioral patterns played a core role in fuelling the discussion about CCSVI. PMID:24425598

  12. NEWS: Institute news

    NASA Astrophysics Data System (ADS)

    2000-07-01

    When Mary took up her appointment in the Institute's Education Department in June 1997, she indicated that she wished to return to teaching in two or three years. We have just heard that in September she will be joining the staff of the Science Department at Camden Girls' School, London. Mary's departure from the Institute is a great loss to the Department, where she has worked tirelessly, and with great imagination, to support those who teach physics at all secondary levels - and at primary level too when the opportunity presented itself. She has made tremendous contributions to the careers side of the Department's work, supporting careers events, providing informal training for others willing to do the same, helping to develop new careers materials and identifying people whom the Institute could use as role models or as the subject of case studies in print or electronic publications. Mary has been equally happy and willing to support pupils, students and teachers, and has been a wonderful role model herself, coming from an industrial research background, training for teaching after a career break and willing and able to teach biology, chemistry and design technology as well as physics. Mary has also written and edited Phases virtually single-handed. We are delighted to hear that Mary will continue to support the department's work as one of its teacher `volunteers'. Ilya Eigenbrot We are pleased to report that Ilya Eigenbrot, who will be known to some through his work at the Royal Institution and his appearances at the Christmas Lectures in a technical support role, has agreed to give the IOP Schools (touring) Lecture next year. The subject will be Lasers and this will follow nicely on to Zbig's lecture this year. Resources (print) Physics on Course The tenth issue of the Institute's popular guide to higher education, Physics on Course 2001, will be published early in July and distributed to all schools and colleges in the United Kingdom and the Republic of Ireland. Its pages are brimming with useful information to help sixth-formers and college students who wish to study physics make the very important decision regarding their particular choice of course and university. Under the heading `Summary tables of physics courses' every university listed in the publication has a table which includes all the courses on offer, their entrance requirements, duration and the awards given. Another section of the book entitled `Departmental information' includes data on the teaching and assessment styles of the Physics Department, special facilities plus a contact name and address. These sections, together with an expanded set of case studies of recent students and various other interesting articles, make this publication a must for anyone who is considering studying physics at university. Copies of Physics on Course 2001 will be available from Leila Solomon, Education Department, Institute of Physics, 76 Portland Place, London, W1N 3DH. The Particle Physics Wallchart (PCET) This full-colour chart, with a set of Teachers Notes, was published recently. It has been developed by PCET with Professor Peter Kalmus acting as expert consultant. The cost of the chart and notes is £7.75 plus VAT and copies can be purchased from PCET, 27 Kirchen Road, London W13 0UD (fax: 020 8566 5120). Inspire II The second part of Inspire was published in the Spring. It is a highly visual, full-colour leaflet which can be used as a stand-alone item but which was designed to `nest' inside the first four-page spread which was distributed in February. The occupational areas for physicists covered in the second leaflet include the media/leisure, finance and engineering (at technician level) industries. The third of the intended four sheets will be published later this year. (Copies of Inspire II have been included in the Affiliated schools/colleges package; other schools/colleges will be sent copies on request.) Nanotechnology - a technical brief The Industrial Affairs Department of the Institute is working on a series of Technical Briefs to broaden the provision of physics information to Members. The first title in the series, `Nanotechnology', is due to be published last month. The aim of this new series is to provide technical updates on current applications of physics, targeted at the nonspecialist scientist and engineer. The emphasis will be on burgeoning areas of physics with potential application across several or many fields. `Nanotechnology', for example, will sketch the background to the field, indicate the current state of the art and give a realistic view on future developments. The target readers are Institute of Physics Members in general, not specialists in nanotechnology or related topics and, in this respect, the Briefs could be of great interest to teachers. They are free of charge to Members but £7.50 for non-members. To obtain a copy, contact Emma Woods on 020 7470 4927 or by e-mail (emma.woods@iop.org). Courses Physics Update: 8-10 July, University of York The information leaflet/booking form for this course was sent to schools and colleges at the beginning of this term. Lecture topics include Ultrasonic imaging, Chaos, and The search for extra-terrestrial intelligent life. There will be workshops on New activities from Salters Horners physics, Computer modelling in A2 physics and Misconceptions in the learning of forces. Further information and booking forms are available from Leila Solomon. The venues and dates of subsequent Update courses are: 8-10 December, Oxford University 31 March-2 April 2001, Malvern College 7-9 July 2001, Royal Holloway College, London Teaching Physics INSET Days Following successful pilot runs in the summer term last year and at IOP Congress, the Education Department is organizing four (possibly five) INSET days for those teaching physics at KS3 without a strong background in the subject. The recent dates in June were all fully booked. The programme will be basically same for all the events with an introductory talk Inspiring Your Pupils, followed by workshops on Forces, Electricity and Light designed to enhance participants' knowledge of physics and its applications and to improve their confidence in teaching that knowledge. At each venue there will be an opportunity to tour the facilities, meet the staff and to assess the potential for school visits or link activities. The fee including course materials, lunch and other refreshments is £25. Leaflets have been sent to schools in the localities but further copies will be sent on request. Places are limited and prompt booking is essential. Further courses are planned for the autumn term as follows: Explore@Bristol (4 October) and possibly London in November. Substantially similar events may be organized for those teaching physics at KS4 in the Spring term of 2001. Physics Discipline Network Workshop: 14/15 September, University of Leeds `Our assessment of students and the media's assessment of us!' is the focus of this two-day event. The network was established in 1994 to encourage debate and discussion of teaching and learning initiatives among university physicists. Over the past five years the annual workshops have attracted over 200 delegates from most of the UK university physics departments. This year's workshop looks set to get off to a lively start with Professor Paul Black questioning the typical format of university physics examinations. This will be followed by a session on `A question of chemistry - creative problems for critical thinkers' which it is hoped will prompt thinking about comparable approaches in physics. This is just the start of a full programme of presentations including grass roots innovative practices as well as lead speakers of national prominence. Attention will focus on schools, too, with an input on the Pupil Researcher Initiative as a way of promoting physics at school level. Further details of this event are available from Dr Ashley Clarke in the Department of Physics and Astronomy at the University of Leeds. Physics at Work Exhibition: 12-14 September, University of Cambridge The year 2000 Exhibition will be the 16th organized by Brenda Jennison. The exhibition will be held at the Cavendish Laboratory and further details can be obtained from Brenda at the University (tel: 01223 332888, fax: 01223 332894 or e-mail: bmj10@cam.ac.uk). News on GNVQ science The Institute of Physics and the Royal Society of Chemistry are currently financing the compilation of a directory of resources to assist teachers in identifying and selecting suitable materials for teaching the new GNVQ science specifications. Work on the first part of the directory will soon be completed and it is hoped to publish the material in both print and electronic forms before the end of the summer term. This first part covers resources - all evaluated by practising GNVQ teachers - supporting the teaching of the compulsory units for Advanced GNVQ Science. A small team comprising a physics teacher, a chemistry teacher and a biology teacher, all involved with GNVQ programmes and led by Dr Ken Gadd, has carried out the work. They have established a network of teachers around the country to help with the evaluation of curriculum materials. The next part of the project will be to examine the feasibility of providing a similar listing for the optional units at this level. Future development, depending on the availability of funds, will extend the project to Intermediate level programmes in science, including the Part One, once its structure has been agreed at QCA. Further information about the Directory and the next phase of development will be available in the autumn. Activities Physics on Stage The future of science, technology and the ensuing wealth creation potential for Britain will depend on the quality of science education in schools today. Yet the numbers studying physics, which underpins science and engineering, are falling. This problem is currently evident throughout Europe. CERN, ESA and ESO (the European centres for high-energy physics, cosmology, space and astronomy) have just launched Physics on Stage, a Europe-wide programme which aims to draw attention to some of the best practices in physics teaching in schools and colleges. During this year, national programmes are being planned in 22 nations, leading on to a celebratory event at CERN during the European Week for Science and Technology (6-11 November). Here 400 delegates from the 22 participating nations will gather to present selected projects. The UK will have 40 delegates present, funded by the EC and we are seeking practising teachers to contribute their simple, transferable, practical ideas. These can be kitemarked and your school can use the Physics on Stage logo. We would like to hear from both primary and secondary schools in the UK. Teachers can apply to join the delegation by saying what they have to offer to the festival and how they would contribute to the dissemination of good practice afterwards. This would be an opportunity to discover what novel ideas and insights there are on the continent and then to share what you have learned with colleagues at home. It would also be an excellent opportunity to show off some of the good practice from UK classrooms. In return for the week's trip to Geneva (and cover) we ask that participants commit themselves to sharing what they have learned with UK teachers - through meetings, advanced skills teaching or perhaps even writing an article (for Physics Education?). Applications should be supported by a letter from your headteacher. Schools, other organizations and individuals may apply for a kite-mark for a project but the application should be supported by a letter from someone unconnected with the organization of the project. Nominations should be sent to Dr Steven Chapman, Secretary to the UK National Steering Committee Physics on Stage, 76 Portland Place, London W1N 3DH (e-mail: steven.chapman@iop.org), from whom further information about this initiative can also be obtained. More details can additionally be found on the website at www.physics-on-stage.co.uk. The closing date for kite-marking of projects is 30 September and that for applications to travel to Geneva is 30 July.

    The Dalian Coherent Light Source (DCLS) is a Free electron laser (FEL) user facility currently under construction in the northeast of China. It is designed to work on high gain high harmonic principle with the capability of wavelength continuously tunable in the EUV regime of 50-150 nm. The light source has unique features such as the turntable radiation frequency, wide spectral range, high brightness and peak power, very short pulse time structure, etc. A key diagnostic task in DCLS is the on-line source spectral characteristic recording during the source development, and for the definition of the experimental conditions. For this purpose, an online grazing incidence spectrometer with a toroidal mirror and a variable-line-spacing plane grating is designed and presented in this paper to monitor each single FEL pulse. A circular stage is chosen to fit the focal curve and to realize the wavelength scanning. This scanning mechanics is simpler and stable. Resolving power (?/??) of this spectrometer is better than 12,000 in the whole wavelength range.

    The 'Computational Crystallography Toolbox' (cctbx, http://cctbx.sourceforge.net/) is the open-source component of the Phenix project (http://www.phenix-online.org/). Most recent cctbx developments are geared towards supporting new features of the phenix.refine application. Thus, the open-source mmtbx (macromolecular toolbox) module is currently being most rapidly developed. In this article we give an overview of some of the recent developments. However, the main theme of this article is the presentation of a light-weight example command-line application that was specifically developed for this newsletter: sequence alignment and superposition of two molecules read from files in PDB format. This involves parameter input based on the Phil module presented in Newsletter No. 5, fast reading of the PDB files with the new iotbx.pdb.input class, simple sequence alignment using the new mmtbx.alignment module, and use of the Kearsley (1989) superposition algorithm to find the least-squares solution for superposing C-alpha positions. The major steps are introduced individually, followed by a presentation of the complete application. The example application is deliberately limited in functionality to make it concise enough for this article. The main goal is to show how the open-source components are typically combined into an application. Even though the example is quite specific to macromolecular crystallography, we believe it will also be useful for a small-molecule audience interested in utilizing the large open-source library of general crystallographic algorithms (see our previous articles in this newsletter series) to build an application. We describe recent developments of the Computational Crystallography Toolbox.

    We report on the implementation of a tool for the analysis of second-order elastic stiffness tensors, provided with both an open-source Python module and a standalone online application allowing the visualization of anisotropic mechanical properties. After describing the software features, how we compute the conventional elastic constants and how we represent them graphically, we explain our technical choices for the implementation. In particular, we focus on why a Python module is used to generate the HTML web page with embedded Javascript for dynamical plots. PMID:27199239

    Some of the {gamma}-ray sources detected by the H.E.S.S. experiment display irregular, often flare-like emission behaviour. A method to detect these outbursts as fast as possible is highly desirable. At H.E.S.S., first results from an offline analysis of pre-calibrated data can be obtained on-site approximately one hour after run end. We present a development and implementation of online analysis software that performs calibration and analysis of data at the time they are being taken allowing for a fast confirmation of observational results and appropriate reaction by the on-site shift crew.

    2004-05-01

    A high temperature electron beam ion source (HTEBIS) for production of single charge ions of refractory elements was built and on-line used for production of isotopes of Fe, Co, Cu, Rh, and Pd. Off-line ionization efficiency measurement of pointed out elements have been carried out. The yields of some neutron rich isotopes of these elements, when HTEBIS was used with the uranium carbide target have been measured. The measured yields have been compared with calculated ones, obtained from experimentally defined cross-sections. A new designed and off-line tested version of HTEBIS with electron emitting cathode placed from the extraction electrode side has been discussed.

    Those who are a part of this program take materials about the Journal to workshops, outreach programs, seminars, regional meetings, award nights, short courses, and other events at home and abroad, places where people who are interested in chemical education gather. Given about three weeks notice, we can outfit you with a variety of materials that will help others get tuned in to the good things that are happening in chemical education. We can send you an assortment of Journal issues, subscription forms, our Publications/Software Catalog, reprints from the Viewpoints series, copies of Classroom Activities, or JCE Gift Award Certificates, assuming that supplies are available. Of course we can arrange for the group to have temporary access to JCE Online. We can send you a brochure about the Ambassador program or answer any questions - just ask: email to jce@chem.wisc.edu; phone 1-800-991-5534 (U.S.) or 608-262-5153 (non-U.S.); fax 608-265-8094. If by chance you were a Journal Ambassador in 1999 but your name was not included, just let us know so that you can be recognized in a future column. Gift Subscription Awards As spring, the season of awards, approaches, we remind you of our handy Gift Certificates (a replica is shown on page 142). A gift of the Journal is not only affordable (gift subscriptions are 37/year (U.S.), 50/year (non-U.S.), but has lasting value. This is a really good way to help someone just starting out on a teaching career. An idea worth sharing comes from Carl Minnier of Essex Community College in Baltimore. He is chair of the Student Awards Committee of the Maryland Section of the ACS. This section has asked for 25 certificates because they honor annually an outstanding student from each of the two-year and four-year colleges within the territory of the Maryland Section. Want another interesting idea: give a one-year subscription to each Undergraduate Research Symposium participant. Classroom Activities for Outreach Many of our readers are involved with outreach programsindividually in their child's class, in a regional group that visits schools, in a van program, or as a demonstrator at their local science museum. Many readers have enthusiastically reported that our Classroom Activities series is a great resource for such programs. Since the Activities are designed for a high school classroom or lab (Activity 24 in this continuing series can be found in this issue), they are purposely not demanding of equipment, facilities, or time. But outreach activities often take place in very restricted environments, perhaps without sinks or electricity, sometimes with limited table space. So that we can provide timely advice in recommending activities for you to take "on the road", Nancy Gettys and Erica Jacobsen of the Journal staff have done an analysis of each, recommending whether it might be done in a workshop setting (where tables, a sink, and electricity could be expected) or in a booth (probably no sink and very limited space). There are also very useful notes. Some sample entries are: Activity:What's Gluep? Characterizing a Cross-Linked Polymer. J. Chem. Educ. 1998, 75, 1432A (November 1998). Workshop?yes Booth?could show properties of pre-made gluep Notes:Need access to water. Can be messy. People usually enjoy the activity. Works well. Activity:CD Light: An Introduction to Spectroscopy.

    Courses, Seminars, Meetings, Opportunities

    Cosmos in the Classroom 2 A national symposium on the trials and tribulations of teaching astronomy to college non-science majors will be held at the Pasadena, California, Convention Center on July 17-19, 2000, as part of the 112th Annual Meeting of the Astronomical Society of the Pacific. Designed for everyone who teaches introductory astronomy, the symposium will focus on ways to improve teaching, to involve students more effectively, and to put astronomy in a wider context. Specific discussion topics will include: getting out of lecture mode, using the Web effectively, dealing with creationism and astrology, and laboratory and observation projects. The 2.5-day program will involve panels of mentor instructors, an exchange of handouts and teaching resources, hands-on workshops for trying new techniques and approaches, and lots of time for discussion. Participants will range from veteran instructors to nervous graduate students about to teach their first solo course. We especially hope to involve those teaching astronomy in small colleges without extensive astronomy research programs, and colleagues in other sciences who teach astronomy on a part-time basis. To get on the mailing list for the meeting, send your name, institution, email, and postal mailing address (indicating an interest in the 2000 Education Symposium) via: email: meeting@aspsky.org; fax: 415/337-5205 (Attn: 2000 Education Symp.) mail: 2000 Education Symposium, ASP, 390 Ashton Avenue, San Francisco, CA 94112.

Soaring Endowments: Research Corp. Report "The Midas Touch: Do Soaring Endowments Have Any Impact on College Science?" is the title of their 1998 annual report, just published by Research Corporation. In it the foundation reports that endowment growth appears to have only incidental effects on ongoing support for college research and education in the physical sciences. More likely targets for expenditures are new and remodeled buildings and student aid. Interviews with college administrators support the conclusion that large endowments do not guarantee the funds needed to hire enough faculty scientists to teach and do related research with students, to house the sciences in up-to-date buildings, or equip laboratories with modern instrumentation. Copies of "The Midas Touch" are available without charge from Research Corporation, 101 North Wilmot Road, Suite 250, Tucson, AZ 85711.

    The first on-line tests of the ion sources to provide radioactive ion beams of {sup 69,70}As and {sup 17,18}F for the Holifield Radioactive Ion Beam Facility (HRIBF) have been performed using the UNISOR facility at HRIBF. The target/ion source is an electron beam plasma (EBP) source similar to the ISOLDE design. The measured efficiencies for {sup 69}As and {sup 70}AS were 0.5 {+-} 0.2% and 0.8 {+-} 0.3%, respectively. The arsenic hold-up time in the tested target ion source was 3.6 {+-} 0.3 hours as measured with {sup 72}As at a target temperature of 1300 {degrees}C. The measured efficiencies for {sup 17}F and {sup 18}F were 0.0052 {+-} 0.0008% and 0.06 {+-} 0.02%, respectively. The source hold-up time for fluorine was measured with Al{sup 18}F since 88% of the observed radioactive fluorine was found in this molecule. The Al{sup 18}F hold-up time was 16.4 {+-} 0.8 minutes at a target temperature of 1470 {degrees}C.

Name: Jane L Doe Whenever asked for your password, enter your subscriber number, the first (5-digit) number on the second line of the label. Password: 99990 New IP-Address Option for Libraries While standard username/password access (where all users share the same access information) may be fine for some libraries, others find this system too limited and therefore unworkable. Such institutions have requested access by IP address, with no prompting for UserName and Password. We believe that this is just the tip of the iceberg and that many, if not most, library and institutional subscribers will want this type of access in the near future. Therefore we have added an IP-Address subscription option for libraries and institutions. With this option, the library or institution provides us with a list of all IP numbers that will receive access. Any desktop computer using one of these IP numbers will have immediate access, without the prompt for name and password. Because this requires considerably more administrative work on our end, there is a somewhat larger (but reasonable) fee. Please make your librarian aware of this new option that will provide you and all your colleagues with desktop access to JCE. Immediate Access to Online At present new subscribers are not able to get immediate access to JCE Onlinea limitation for subscribers who order over the telephone using a credit card. We now have an arrangement with our subscription fulfillment agent to give new subscribers immediate access to JCE Online by a guest account. The temporary guest account information will be provided as a part of the telephone order; when the new account is active, the account information will be emailed. Remember to Provide Your Email Address Knowing your email address has become important for Journal communication. In addition to account information, we will send an order confirmation to each subscriber who provides an email address. For those who want it, we intend, in the near future, to send an email message announcing when each month's issue goes online. We do not sell or give email addresses to anyone else. Keeping Up to Date with JCE Online JCE Online will continue to change and expand, as the technology around us changes and as new features and columns are added. The best way to keep abreast of new developments is to look for the JCE Online column in both print and online. Jon Holmes, editor of JCE Online, uses this column to keep readers in touch with the latest happenings:
    • JCE Online FAQs (March 1999, p 446)
    • JCE Online 99 (April 1999, p 584)
    • JCE Feature Columns (May 1999, p 718)
    • Molecular Modeling (June 1999, p 871)
    JCE: A Good Deal That Keeps Getting Better If you carry copies of JCE around in hopes of finding time to read them, you may think they are getting heavierand they are. Your Journal was more than a third bigger in 1998 than it was in 1995! We have printed more pages every year since 1996 (see graph for the past 25 years). We estimate that you will receive more than 2000 pages this year and even more next year. This is more pages than at any time in the Journal 's history, excepting the four years 1929-1932, when the pages were smaller. We are printing more pages because we need to. We have many good manuscripts that have been peer reviewed and accepted and now are awaiting publication in print. The time between acceptance of a manuscript and its publication is already too long. Unless we print more pages, it will grow longer. For the past three years we have been slowly but steadily reducing this publication lag, and we don't want to stop now. JCE accepts only those manuscripts that pass strict peer review (fewer than half the number we receive), but we are receiving more manuscripts each year, with no apparent decline in quality. A recent analysis of our expenses revealed that to process a subscription order, print 12 issues of JCE, and mail those 12 issues to you costs about 37 - exactly what we charged in 1999 for an individual subscription. This 37 does not include the cost of the editorial work that goes into making JCE an excellent journal: evaluating, reviewing, and working with authors to improve manuscripts, copy editing and preparing proofs, and laying out and desktop publishing each of the 600 articles we publish each year. JCE is a nonprofit operation, but we cannot survive if we provide a product whose production costs exceed income. Therefore the Board of Publication found it necessary to increase the individual subscription fee for next year to 42. This is a 31% increase over 1995 (less than 21% if inflation is taken into account), which is significantly below the estimated 40% increase in number of pages you will receive in 2000. Another way to see the tremendous value of JCE is to compare the cost per page for various journals. JCE costs less per printed page than any other journal we know. A quick survey revealed that cost per page ranges from 2 cents for JCE to 2-28 cents for various ACS journals to 46 cents for a science education research journal published by a commercial publisher to as much as 2 for a commercially published science research journal. JCE 's costs to institutional subscribers such as libraries are even more favorable by comparison with other journals, because we want JCE to be accessible to libraries in high schools and small colleges. How can we afford to be such a bargain? The entire community of chemical education contributes to writing, reviewing, and testing the materials we publish. Some members volunteer even more time as feature editors. The editorial staff work hard and often spend more than the typical work week doing their jobs superlatively and making this a great Journal. The Board of Publication, the Division of Chemical Education, and everyone associated with the Journal are dedicated to providing our readers with the best possible publication at the lowest possible cost. All that effort counts for a lot, and you are the beneficiary. What can you do to help continue this tradition of excellence at minimal cost? Become a JCE Ambassador. Ask others to join with us as subscribers. Or give them gift subscriptions (an even better bargain) and encourage them to continue to subscribe. The more subscribers we have, the less the cost to each. Also, volunteer your time as an author, reviewer, column editor, or in some other capacity. JCE is a great journal because its readers have given of themselves to make it that way. Please continue to work with us to keep it that way.

  13. Inquiring minds acquiring wellness: uses of online and offline sources for health information.

    PubMed

    Dobransky, Kerry; Hargittai, Eszter

    2012-01-01

    Variation in ability to access and use health information is a key pathway through which social status may impact health. Digital media offer new opportunities for health information seeking, potentially lowering barriers to such content. Using a data set with nuanced information about what sources a diverse group of college students consults for different types of health material, coupled with detailed measures of Internet experiences, this article explores factors related to where young adults turn for health content. Results suggest considerable sex differences in practices across sources of health information. We also find differences in Hispanic students' actions based on parents' country of origin across sources. Finally, challenging assumptions about the universal savvy of young adults, findings suggest that those who are more highly skilled with the Internet are more likely to use it for health information seeking, and Internet experiences are especially important for explaining who turns to online discussions in this realm. Our findings not only contribute to a better understanding of health information seeking and health inequality, but also point to possible sites of intervention to ameliorate health disparities.

  3. Chemistry Is in the News: Taxonomy of authentic news media-based learning activities1

    NASA Astrophysics Data System (ADS)

    Glaser, Rainer E.; Carson, Kathleen M.

    2005-09-01

    A brief history is given of approaches that aim at achieving a connectedness of the content of organic chemistry courses to real world issues. Recently, such approaches have relied more and more on online media resources, the tools of the Internet and the World Wide Web. We propose a six-level taxonomy of ‘authentic news media-based learning activities’ to provide a conceptual framework for the description and discussion of such approaches. The Chemistry Is in the News project was designed to allow students to draw explicit connections between the course content and real world issues in ways that engage the students in a full range of cognitive skills. The activities consisted in the study, creation, and peer review of news portfolios by student collaborative groups. A news portfolio consists of an authentic news article taken from the popular press with interpretive comments and questions.

  4. On-line combustion of samples for AMS and ion source developments at ORAU

    NASA Astrophysics Data System (ADS)

    Bronk Ramsey, C.; Humm, M. J.

    2000-10-01

    Each stage in the handling of radiocarbon samples provides an additional opportunity for contamination and increased cost. For large samples, graphitization is worthwhile since it allows precise AMS measurements to be made in a short time. Some samples, however, do not require high precision. These include small samples, for which high precision is impossible, and samples for which only an approximate date is required. In these cases, there is an advantage in burning the samples and then introducing the CO 2 directly into a gas ion source. ORAU has developed a system for performing on-line combustion, which is being tested for routine use. This paper presents the performance characteristics and explains the main design features. Such systems are expected to be useful for small samples in radiocarbon dating, the pre-screening of radiocarbon ages and in biomedical applications. The hybrid (graphite and CO 2) ion source at Oxford has also been upgraded to incorporate a 40-target sample changing mechanism. This can be used both for graphite samples and for the targets required for measurements on CO 2.

  8. Hot news recommendation system from heterogeneous websites based on bayesian model.

    PubMed

    Xia, Zhengyou; Xu, Shengwu; Liu, Ningzhong; Zhao, Zhengkang

    2014-01-01

    The most current news recommendations are suitable for news which comes from a single news website, not for news from different heterogeneous news websites. Previous researches about news recommender systems based on different strategies have been proposed to provide news personalization services for online news readers. However, little research work has been reported on utilizing hundreds of heterogeneous news websites to provide top hot news services for group customers (e.g., government staffs). In this paper, we propose a hot news recommendation model based on Bayesian model, which is from hundreds of different news websites. In the model, we determine whether the news is hot news by calculating the joint probability of the news. We evaluate and compare our proposed recommendation model with the results of human experts on the real data sets. Experimental results demonstrate the reliability and effectiveness of our method. We also implement this model in hot news recommendation system of Hangzhou city government in year 2013, which achieves very good results. PMID:25093207

    Background The Internet has increasingly become a popular source of health information by connecting individuals with health content, experts, and support. More and more, individuals turn to social media and Internet sites to share health information and experiences. Although online health information seeking occurs worldwide, limited empirical studies exist examining cross-cultural differences in perceptions about user-generated, experience-based information compared to expertise-based information sources. Objective To investigate if cultural variations exist in patterns of online health information seeking, specifically in perceptions of online health information sources. It was hypothesized that Koreans and Hongkongers, compared to Americans, would be more likely to trust and use experience-based knowledge shared in social Internet sites, such as social media and online support groups. Conversely, Americans, compared to Koreans and Hongkongers, would value expertise-based knowledge prepared and approved by doctors or professional health providers more. Methods Survey questionnaires were developed in English first and then translated into Korean and Chinese. The back-translation method ensured the standardization of questions. Surveys were administered using a standardized recruitment strategy and data collection methods. Results A total of 826 participants living in metropolitan areas from the United States (n=301), Korea (n=179), and Hong Kong (n=337) participated in the study. We found significant cultural differences in information processing preferences for online health information. A planned contrast test revealed that Koreans and Hongkongers showed more trust in experience-based health information sources (blogs: t 451.50=11.21, P<.001; online support group: t 455.71=9.30, P<.001; social networking sites [SNS]: t 466.75=11.36, P<.001) and also reported using blogs (t 515.31=6.67, P<.001) and SNS (t 529.22=4.51, P<.001) more frequently than Americans. Americans showed a stronger preference for using expertise-based information sources (eg, WebMD and CDC) compared to Koreans and Hongkongers (t 360.02=3.01, P=.003). Trust in expertise-based information sources was universal, demonstrating no cultural differences (Brown-Forsythe F 2,654=1.82, P=.16). Culture also contributed significantly to differences in searching information on behalf of family members (t 480.38=5.99, P<.001) as well as to the goals of information searching. Conclusions This research found significant cultural differences in information processing preferences for online health information. Further discussion is included regarding effective communication strategies in providing quality health information. PMID:26976273

    The Laser Ion Source and Trap (LIST) provides a new mode of operation for the resonance ionization laser ion source (RILIS) at ISOLDE/CERN, reducing the amount of surface-ionized isobaric contaminants by up to four orders of magnitude. After the first successful on-line test at ISOLDE in 2011 the LIST was further improved in terms of efficiency, selectivity, and reliability through several off-line tests at Mainz University and at ISOLDE. In September 2012, the first on-line physics experiments to use the LIST took place at ISOLDE. The measurements of the improved LIST indicate more than a twofold increase in efficiency compared to the LIST of the 2011 run. The suppression of surface-ionized francium contaminants has enabled the first in-source laser spectroscopy of 217Po and 219Po.

    Organic compounds comprise a major fraction of tropospheric aerosol and understanding their chemical complexity is a key factor for determining their climate and health effects. We present and characterize here a new online technique for measuring the detailed chemical composition of organic aerosols, namely extractive electrospray ionization mass spectrometry (EESI-MS). Aerosol particles composed of soluble organic compounds were extracted into and ionized by a solvent electrospray, producing molecular ions from the aerosol with minimal fragmentation. We demonstrate here that the technique has a time resolution of seconds and is capable of making stable measurements over several hours. The ion signal in the MS was linearly correlated with the mass of aerosol delivered to the EESI source over the range tested (3-600 μg/m(3)) and was independent of particle size and liquid water content, suggesting that the entire particle bulk is extracted for analysis. Tandem MS measurements enabled detection of known analytes in the sub-μg/m(3) range. Proof-of-principle measurements of the ozonolysis of oleic acid aerosol (20 μg/m(3)) revealed the formation of a variety of oxidation products in good agreement with previous offline studies. This demonstrates the technique's potential for studying the product-resolved kinetics of aerosol-phase chemistry at a molecular level with high sensitivity and time resolution. PMID:23710930

    2015-01-01

    Background In the context of the Affordable Care Act, there is extensive emphasis on making provider quality transparent and publicly available. Online public reports of quality exist, but little is known about how visitors find reports or about their purpose in visiting. Objective To address this gap, we gathered website analytics data from a national group of online public reports of hospital or physician quality and surveyed real-time visitors to those websites. Methods Websites were recruited from a national group of online public reports of hospital or physician quality. Analytics data were gathered from each website: number of unique visitors, method of arrival for each unique visitor, and search terms resulting in visits. Depending on the website, a survey invitation was launched for unique visitors on landing pages or on pages with quality information. Survey topics included type of respondent (eg, consumer, health care professional), purpose of visit, areas of interest, website experience, and demographics. Results There were 116,657 unique visitors to the 18 participating websites (1440 unique visitors/month per website), with most unique visitors arriving through search (63.95%, 74,606/116,657). Websites with a higher percent of traffic from search engines garnered more unique visitors (P=.001). The most common search terms were for individual hospitals (23.25%, 27,122/74,606) and website names (19.43%, 22,672/74,606); medical condition terms were uncommon (0.81%, 605/74,606). Survey view rate was 42.48% (49,560/116,657 invited) resulting in 1755 respondents (participation rate=3.6%). There were substantial proportions of consumer (48.43%, 850/1755) and health care professional respondents (31.39%, 551/1755). Across websites, proportions of consumer (21%-71%) and health care professional respondents (16%-48%) varied. Consumers were frequently interested in using the information to choose providers or assess the quality of their provider (52.7%, 225/427); the majority of those choosing a provider reported that they had used the information to do so (78%, 40/51). Health care professional (26.6%, 115/443) and consumer (20.8%, 92/442) respondents wanted cost information and consumers wanted patient narrative comments (31.5%, 139/442) on the public reports. Health care professional respondents rated the experience on the reports higher than consumers did (mean 7.2, SD 2.2 vs mean 6.2, SD 2.7; scale 0-10; P<.001). Conclusions Report sponsors interested in increasing the influence of their reports could consider using techniques to improve search engine traffic, providing cost information and patient comments, and improving the website experience for both consumers and health care professionals.

The database includes public and private courses at all levels from more than 15 countries and includes only those courses that can be completed fully online. Courses vary from graduate-level engineering offerings to simple "How to" courses. The database provides access to courses and programs leading to accredited degrees, diplomas, and certificates. Professional development and personal interest courses are also included. Students can access course information by browsing subject areas or by searching specific fields. Hotlinks connect students directly to the delivering institutions. In the past year, there has been an exponential rise in the number of courses being offered online, from fewer than 2,000 in January 1998 to more than 10,000 in December 1998. It is expected that there will be more than 40,000 online courses by the year 2000. The TeleCampus Online Course Database provides students with a means of finding information on courses that meet their needs. The database can be accessed from TeleCampus at http://telecampus.edu. Change in the Introductory Chemistry Course, an Online Course An online conference, Proposals for Change in the Introductory Chemistry Course, will take place from March 29 to April 10, 1999. The conference will be chaired by James N. Spencer, Chemistry Department, Franklin & Marshall College, Lancaster, PA 17604; j_spencer@acad.fandm.edu. While both process and content need to be considered in making changes, this conference will be limited to a discussion of content. It will take the approach that if we begin to examine the current content and how and why certain topics came to be considered as essential for the course, we may be able to approach a common curriculum so that the process of how to best to implement it may then be developed. Stephen J. Hawkes of Oregon State University compiled suggestions for the content of general chemistry and served as leader of the Zero Base Course discussion group for the Task Force on the General Chemistry Curriculum. The goal of the zero base approach is a detailed curriculum in which topics are developed so that students understand the phenomena considered necessary for the course. This analysis requires that the principles that should be in the course be identified, that those not necessary be removed, and perhaps additional principles be added. This online conference will list more than 100 proposals compiled from many viewpoints. Proposals are worded as debatable propositions to engender serious discussion. After discussion, amendment, deletion, extension, and some consensus, the proposals will be distributed to the chemistry community in various forms. Future discussions are also planned.

    A content analysis of The New York Times' Science Times section from 1998 to 2012 found evidence of increased source diversity in use of scientific journals as news sources. Science Times increased the frequency at which it cited journals, the number of different journals that it cited, and the number of disciplines represented by cited journals. The results suggest that online availability of a wide array of scientific journals has changed sourcing behaviors. PMID:25063420

  20. OxMaR: open source free software for online minimization and randomization for clinical trials.

    PubMed

    O'Callaghan, Christopher A

    2014-01-01

    Minimization is a valuable method for allocating participants between the control and experimental arms of clinical studies. The use of minimization reduces differences that might arise by chance between the study arms in the distribution of patient characteristics such as gender, ethnicity and age. However, unlike randomization, minimization requires real time assessment of each new participant with respect to the preceding distribution of relevant participant characteristics within the different arms of the study. For multi-site studies, this necessitates centralized computational analysis that is shared between all study locations. Unfortunately, there is no suitable freely available open source or free software that can be used for this purpose. OxMaR was developed to enable researchers in any location to use minimization for patient allocation and to access the minimization algorithm using any device that can connect to the internet such as a desktop computer, tablet or mobile phone. The software is complete in itself and requires no special packages or libraries to be installed. It is simple to set up and run over the internet using online facilities which are very low cost or even free to the user. Importantly, it provides real time information on allocation to the study lead or administrator and generates real time distributed backups with each allocation. OxMaR can readily be modified and customised and can also be used for standard randomization. It has been extensively tested and has been used successfully in a low budget multi-centre study. Hitherto, the logistical difficulties involved in minimization have precluded its use in many small studies and this software should allow more widespread use of minimization which should lead to studies with better matched control and experimental arms. OxMaR should be particularly valuable in low resource settings. PMID:25353169

    2015-01-01

    Online social media such as Twitter are widely used for mining public opinions and sentiments on various issues and topics. The sheer volume of the data generated and the eager adoption by the online-savvy public are helping to raise the profile of online media as a convenient source of news and public opinions on social and political issues as well. Due to the uncontrollable biases in the population who heavily use the media, however, it is often difficult to measure how accurately the online sphere reflects the offline world at large, undermining the usefulness of online media. One way of identifying and overcoming the online-offline discrepancies is to apply a common analytical and modeling framework to comparable data sets from online and offline sources and cross-analyzing the patterns found therein. In this paper we study the political spectra constructed from Twitter and from legislators' voting records as an example to demonstrate the potential limits of online media as the source for accurate public opinion mining, and how to overcome the limits by using offline data simultaneously.

    Background New media changes the dissemination of public health information and misinformation. During a guest appearance on the Today Show, US Representative Michele Bachmann claimed that human papillomavirus (HPV) vaccines could cause “mental retardation”. Objective The purpose of this study is to explore how new media influences the type of public health information users access, as well as the impact to these platforms after a major controversy. Specifically, this study aims to examine the similarities and differences in the dissemination of news articles related to the HPV vaccination between Google News and Twitter, as well as how the content of news changed after Michele Bachmann’s controversial comment. Methods This study used a purposive sampling to draw the first 100 news articles that appeared on Google News and the first 100 articles that appeared on Twitter from August 1-October 31, 2011. Article tone, source, topics, concerns, references, publication date, and interactive features were coded. The intercoder reliability had a total agreement of .90. Results Results indicate that 44.0% of the articles (88/200) about the HPV vaccination had a positive tone, 32.5% (65/200) maintained a neutral tone, while 23.5% (47/200) presented a negative tone. Protection against diseases 82.0% (164/200), vaccine eligibility for females 75.5% (151/200), and side effects 59.0% (118/200) were the top three topics covered by these articles. Google News and Twitter articles significantly differed in article tone, source, topics, concerns covered, types of sources referenced in the article, and uses of interactive features. Most notably, topic focus changed from public health information towards political conversation after Bachmann’s comment. Before the comment, the HPV vaccine news talked more often about vaccine dosing (P<.001), duration (P=.005), vaccine eligibility for females (P=.03), and protection against diseases (P=.04) than did the later pieces. After the controversy, the news topic shifted towards politics (P=.01) and talked more about HPV vaccine eligibility for males (P=.01). Conclusions This longitudinal infodemiology study suggests that new media influences public health communication, knowledge transaction, and poses potential problems in the amount of misinformation disseminated during public health campaigns. In addition, the study calls for more research to adopt an infodemiology approach to explore relationships between online information supply and public health decisions.

    Motivated by recent financial crises, significant research efforts have been put into studying contagion effects and herding behaviour in financial markets. Much less has been said regarding the influence of financial news on financial markets. We propose a novel measure of collective behaviour based on financial news on the Web, the News Cohesiveness Index (NCI), and we demonstrate that the index can be used as a financial market volatility indicator. We evaluate the NCI using financial documents from large Web news sources on a daily basis from October 2011 to July 2013 and analyse the interplay between financial markets and finance-related news. We hypothesise that strong cohesion in financial news reflects movements in the financial markets. Our results indicate that cohesiveness in financial news is highly correlated with and driven by volatility in financial markets. PMID:24849598

    2015-01-01

    We know little about older adults' use of online and offline health information sources for medical decision making despite increasing numbers of older adults who report using the Internet for health information to aid in patient-provider communication and medical decision making. Therefore we investigated older adult users and nonusers of online and offline sources of health information and factors related to medical decision making. Survey research was conducted using random digit dialing of Florida residents' landline telephones. The Decision Self-Efficacy Scale and the Reliance Scale were used to measure relationships between users and nonusers of online health information. Study respondents were 225 older adults (age range = 50-92 years, M = 68.9, SD = 10.4), which included users (n = 105) and nonusers (n = 119) of online health information. Users and nonusers differed in frequency and types of health sources sought. Users of online health information preferred a self-reliant approach and nonusers of online health information preferred a physician-reliant approach to involvement in medical decisions on the Reliance Scale. This study found significant differences between older adult users and nonusers of online and offline sources of health information and examined factors related to online health information engagement for medical decision making.

    2015-08-01

    Due to the increasing importance of social networking sites as sources of information, news media organizations have set up Facebook channels in which they publish news stories or links to articles. This research investigated how journalistic texts are perceived in this new context and how reactions of other users change the influence of the main articles. In an online experiment (N=197), a Facebook posting of a reputable news site and the corresponding article were shown. The type of user comments and the number of likes were systematically varied. Negative comments diminished the persuasive influence of the article, while there were no strengthening effects of positive comments. When readers perceived the topic as personally relevant, comments including relevant arguments were more influential than comments with subjective opinions, which can be explained by higher levels of elaboration. However, against expectations of bandwagon perceptions, a high number of likes did not lead to conformity effects, which suggests that exemplifying comments are more influential than statistical user representations. Results are discussed with regard to effects of news media content and the mechanisms of social influence in Web 2.0. PMID:26252927

    Europe is severely affected by alien invasions, which impact biodiversity, ecosystem services, economy, and human health. A large number of national, regional, and global online databases provide information on the distribution, pathways of introduction, and impacts of alien species. The sufficiency and efficiency of the current online information systems to assist the European policy on alien species was investigated by a comparative analysis of occurrence data across 43 online databases. Large differences among databases were found which are partially explained by variations in their taxonomical, environmental, and geographical scopes but also by the variable efforts for continuous updates and by inconsistencies on the definition of "alien" or "invasive" species. No single database covered all European environments, countries, and taxonomic groups. In many European countries national databases do not exist, which greatly affects the quality of reported information. To be operational and useful to scientists, managers, and policy makers, online information systems need to be regularly updated through continuous monitoring on a country or regional level. We propose the creation of a network of online interoperable web services through which information in distributed resources can be accessed, aggregated and then used for reporting and further analysis at different geographical and political scales, as an efficient approach to increase the accessibility of information. Harmonization, standardization, conformity on international standards for nomenclature, and agreement on common definitions of alien and invasive species are among the necessary prerequisites.

    As computer technology advances, clinicians and biomedical researchers are becoming more dependent upon information from online databases and information systems. By using specially configured computer workstations and high-speed computer networks, it is now possible to access this information in a rapid and straightforward manner. To empower users by providing these capabilities, the authors are assembling a variety of network workstations to be located throughout Yale-New Haven Medical Center. At the heart of the workstation is NetMenu, a program designed to help users connect to a number of important online information systems, including a hospital order entry and results reporting system, a drug reference, bibliographic retrieval systems, and educational programs. In addition, as part of the National Library of Medicine's Unified Medical Language System (UMLS) project, the authors have developed a local prototype of the UMLS Information Sources Map (ISM) and a companion query assistant program to complement the NetMenu in helping users select and connect automatically to information services relevant to a particular question. The ISM query assistant draws from a listing of many online information sources accessible via local and international networks. PMID:8472006

    Impedance matching circuit between radio frequency (RF) generator and the plasma load, placed between them, determines the RF power transfer from RF generator to the plasma load. The impedance of plasma load depends on the plasma parameters through skin depth and plasma conductivity or resistivity. Therefore, for long pulse operation of inductively coupled plasmas, particularly for high power (∼100 kW or more) where plasma load condition may vary due to different reasons (e.g., pressure, power, and thermal), online tuning of impedance matching circuit is necessary through feedback. In fusion grade ion source operation, such online methodology through feedback is not present but offline remote tuning by adjusting the matching circuit capacitors and tuning the driving frequency of the RF generator between the ion source operation pulses is envisaged. The present model is an approach for remote impedance tuning methodology for long pulse operation and corresponding online impedance matching algorithm based on RF coil antenna current measurement or coil antenna calorimetric measurement may be useful in this regard.

  16. What makes gambling news?

    2001-01-01

    This paper examines print media coverage of casino and electronic gambling in one Canadian province from 1992 to 1997. It provides a theme analysis of content of 234 gambling stories printed in the top two daily newspapers in Nova Scotia. The findings of our content analysis indicate that pro-gambling corporate and political newspaper sources waged a successful media campaign and constructed a powerful public rhetoric in support of new gambling products, services, and institutions. The media, for their part, gave visibility and form to these structured messages. They helped create expectations about gambling and economics and gambling and government. Law and order, and moral and medical discourses about gambling, we discovered, were minor representations in the news coverage, although moral narratives were a pervasive secondary theme in much of the reporting. At bottom, the press produced a "politics of truth" about gambling that was both an external exercise of power and an internal organizational production. PMID:11842527

    Most students entering our introductory astronomy course for nonscience majors arrive not merely lacking scientific facts-they also have misconceptions about the nature of science, and many have a handicapping ``science anxiety'' (in addition to math anxiety). So I have added a ``current science'' requirement to our introductory course. Each student must compile a file of five astronomy news articles taken from readily available sources.

    Online social media such as Twitter are widely used for mining public opinions and sentiments on various issues and topics. The sheer volume of the data generated and the eager adoption by the online-savvy public are helping to raise the profile of online media as a convenient source of news and public opinions on social and political issues as well. Due to the uncontrollable biases in the population who heavily use the media, however, it is often difficult to measure how accurately the online sphere reflects the offline world at large, undermining the usefulness of online media. One way of identifying and overcoming the online–offline discrepancies is to apply a common analytical and modeling framework to comparable data sets from online and offline sources and cross-analyzing the patterns found therein. In this paper we study the political spectra constructed from Twitter and from legislators' voting records as an example to demonstrate the potential limits of online media as the source for accurate public opinion mining, and how to overcome the limits by using offline data simultaneously.

    OBJECTIVE To determine the significance of the English Wikipedia as a source of online health information. DESIGN The authors measured Wikipedia's ranking on general Internet search engines by entering keywords from MedlinePlus, NHS Direct Online, and the National Organization of Rare Diseases as queries into search engine optimization software. We assessed whether article quality influenced this ranking. The authors tested whether traffic to Wikipedia coincided with epidemiological trends and news of emerging health concerns, and how it compares to MedlinePlus. MEASUREMENTS Cumulative incidence and average position of Wikipedia compared to other Web sites among the first 20 results on general Internet search engines (Google, Google UK, Yahoo, and MSN, and page view statistics for selected Wikipedia articles and MedlinePlus pages. RESULTS Wikipedia ranked among the first ten results in 71-85% of search engines and keywords tested. Wikipedia surpassed MedlinePlus and NHS Direct Online (except for queries from the latter on Google UK), and ranked higher with quality articles. Wikipedia ranked highest for rare diseases, although its incidence in several categories decreased. Page views increased parallel to the occurrence of 20 seasonal disorders and news of three emerging health concerns. Wikipedia articles were viewed more often than MedlinePlus Topic (p = 0.001) but for MedlinePlus Encyclopedia pages, the trend was not significant (p = 0.07-0.10). CONCLUSIONS Based on its search engine ranking and page view statistics, the English Wikipedia is a prominent source of online health information compared to the other online health information providers studied.

  5. Comparing the Use of an Online Expert Health Network against Common Information Sources to Answer Health Questions

    2012-01-01

    Background Many workers have questions about occupational safety and health (OSH). It is unknown whether workers are able to find correct, evidence-based answers to OSH questions when they use common information sources, such as websites, or whether they would benefit from using an easily accessible, free-of-charge online network of OSH experts providing advice. Objective To assess the rate of correct, evidence-based answers to OSH questions in a group of workers who used an online network of OSH experts (intervention group) compared with a group of workers who used common information sources (control group). Methods In a quasi-experimental study, workers in the intervention and control groups were randomly offered 2 questions from a pool of 16 standardized OSH questions. Both questions were sent by mail to all participants, who had 3 weeks to answer them. The intervention group was instructed to use only the online network ArboAntwoord, a network of about 80 OSH experts, to solve the questions. The control group was instructed that they could use all information sources available to them. To assess answer correctness as the main study outcome, 16 standardized correct model answers were constructed with the help of reviewers who performed literature searches. Subsequently, the answers provided by all participants in the intervention (n = 94 answers) and control groups (n = 124 answers) were blinded and compared with the correct model answers on the degree of correctness. Results Of the 94 answers given by participants in the intervention group, 58 were correct (62%), compared with 24 of the 124 answers (19%) in the control group, who mainly used informational websites found via Google. The difference between the 2 groups was significant (rate difference = 43%, 95% confidence interval [CI] 30%–54%). Additional analysis showed that the rate of correct main conclusions of the answers was 85 of 94 answers (90%) in the intervention group and 75 of 124 answers (61%) in the control group (rate difference = 29%, 95% CI 19%–40%). Remarkably, we could not identify differences between workers who provided correct answers and workers who did not on how they experienced the credibility, completeness, and applicability of the information found (P > .05). Conclusions Workers are often unable to find correct answers to OSH questions when using common information sources, generally informational websites. Because workers frequently misjudge the quality of the information they find, other strategies are required to assist workers in finding correct answers. Expert advice provided through an online expert network can be effective for this purpose. As many people experience difficulties in finding correct answers to their health questions, expert networks may be an attractive new source of information for health fields in general.

    From April 16, 2006, through May 30, 2013, a team of reviewers from HealthNewsReview.org, many of whom were physicians, evaluated the reporting by US news organizations on new medical treatments, tests, products, and procedures. After reviewing 1889 stories (approximately 43% newspaper articles, 30% wire or news services stories, 15% online pieces [including those by broadcast and magazine companies], and 12% network television stories), the reviewers graded most stories unsatisfactory on 5 of 10 review criteria: costs, benefits, harms, quality of the evidence, and comparison of the new approach with alternatives. Drugs, medical devices, and other interventions were usually portrayed positively; potential harms were minimized, and costs were ignored. Our findings can help journalists improve their news stories and help physicians and the public better understand the strengths and weaknesses of news media coverage of medical and health topics.

  7. Measuring the Interestingness of News Articles

    2007-09-24

    An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

  9. An online cross-scatter correction algorithm for dual-source CT: effects on CT number accuracy and noise

    Dual-source computed tomography (CT) utilizes two x-ray tubes and two detectors simultaneously for the purpose of obtaining 83 msec temporal resolution, 160 kW of x-ray power reserve, or dual-kV (dual-energy) scan capabilities. One inherent constraint of such a design is cross-scatter radiation, which occurs when x-rays from tube A are scattered by the patient and detected by detector B, or vice versa. In the evaluated dual-source CT scanner, an on-line cross-scatter correction technique is used to address this limitation. The technique, available using the 14×1.2-mm collimation, measures scattered radiation along the z axis using detector rows beyond those corresponding to the 16.8 mm nominal total beam width. These direct measurements of scattered radiation are used to correct the measured projection data (scattered and primary radiation) for cross-scatter. A semi-anthropomorphic thorax phantom was used with increasing thicknesses of tissue-equivalent material to simulate small, medium, large and extra-large patients. Phantoms were scanned using single-source and dual-source protocols at 80, 100, 120 and 140 kV, and the mean and standard deviation of the CT numbers in a water-equivalent cylinder located centrally within the phantom measured. For this comparison, images reconstructed using only tube A data from the dual-source acquisition were compared to the single-source images, also obtained using tube A. The differences in the mean and standard deviation of the measured CT numbers between the dual-source tube A images, which were corrected for cross-scatter, and the single-source images, where no cross-scatter existed, were determined for all tube energies and phantom sizes. The differences in mean CT number ranged from -5.2 to 1.3 HU, and the differences in standard deviations ranged from -4.5 to 3.0 HU. We conclude, therefore, that use of the evaluated on-line cross-scatter correction algorithm results in negligible differences in CT number and image noise between single-source and dual-source image data, independent of phantom size and tube potential.

  11. Internet Exercises as a Means of Integrating Late-breaking Astronomy News Into the Introductory Course

    NASA Astrophysics Data System (ADS)

    English, T.

    1997-12-01

    Astronomy is a dynamic science, a point that is sometimes lost on students who slog through the standard treatment of the introductory astronomy course. By integrating the easy access to current research information afforded by the internet and other media, it is possible to tailor the introductory course so that students gain a greater appreciation of the ever-changing landscape of scientific knowledge. For the rest of their lives, the students now taking our courses will be informed of astronomical discoveries through the mass media, which increasingly includes the internet. Through design of assignments that ask students to confront the presentation of late-breaking astronomy news, the introductory astronomy course can help students to be able to process such information long after they have graduated. Caton has taken this idea to an extreme, developing a nonlinear, topics-driven approach to teaching the introductory course (Mercury, 25.6, p.29). Some may be unwilling to suspend the traditional course structure to take such an approach, but there are alternatives. The internet provides easy access to a wider range of breaking astronomy news. Several science news services are available, and many astronomy-related sites offer regular updates. Direct sources for press releases are also easily found. With such access, students can follow stories as they develop. The key to achieving this is through design of assignments that force the students to look for the latest information online. Several variations have been tried at Gardner-Webb, mostly involving student construction of web browser documents that profile particular stories. These assignments build student skills in online research, and communicate that astronomy is an evolving science. Hopefully, they also instill a confidence that allows individual analysis of astronomy (and indeed all science) stories in the news for years to come - well after the specific details of the astronomy course are forgotten.

  12. News from Online: A Spectrum of Color

    1999-06-01

    Thomas Chasteen's site ( http://www.shsu.edu/~chm_tgc/sounds/sound.html) shows how to separate colors using a tuneable monochromator. This graphic comes from his monochromator animation ( http://www.shsu.edu/~chemistry/monochromator/mono.gif). Science Media's site ( http://www.scimedia.com/index.html#scimedia) includes spectroscopy tutorials by Brian Tissue. This graphic can be found at http://www.scimedia.com/chem-ed/light/graphics/em-rad.gif (©1998 B. M. Tissue, www.scimedia.com). All the colors in the rainbow! Now that is a good place to start. Go to About Rainbows ( http://www.unidata.ucar.edu/staff/blynds/rnbw.html), a tutorial from astronomer Beverly Lynds, working with the University Corporation for Atmospheric Research. The tutorial begins with a historical perspective, complete with a sketch by René Descartes in 1637. The bibliography makes this tutorial a good starting point for color exploration. About Rainbows brings you questions to explorefor example, "What happens when you look at a rainbow through dark glasses?" Try the links to these other sites. Project SkyMath: Making Mathematical Connections ( http://www.unidata.ucar.edu/staff/blynds/Skymath.html) is especially for the middle school student. Reproducible masters of these teaching modules can be printed in English and Spanish. From Project SkyMath, you can go to Blue-Skies, a user-friendly graphical interface from The Weather Underground at the University of Michigan ( http://groundhog.sprl.umich.edu/BS.html). And speaking of blue skies, look at a great site, Why is the Sky Blue at http://acept.la.asu.edu/PiN/act/sky/sky.shtml. This is a super site from the Arizona Collaborative for Excellence in the Preparation of Teachers, by the Department of Physics and Astronomy at Arizona State University. If you go to Patterns in Nature: Light and Optics at http://acept.la.asu.edu/PiN/act/activities.shtml, plan to spend some time, for it is wonderful. Another link from the About Rainbows tutorial goes to an experiment that is suitable for older students, Circles of Light--The Mathematics of Rainbows at http://www.geom.umn.edu/education/calc-init/rainbow/. Frederick J. Wicklin and Paul Edelman of the University of Minnesota note that this comprehensive lab is based on a module developed by Steven Janke. Go back to About Rainbows to link to a Java applet, allowing you to change the incident angle and color of light striking a water droplet. This great teaching device is from Fu-Kwun Hwang of the National Taiwan Normal University at http://science.kongju.ac.kr/phys/shin/experiment/ntnujava /Rainbow/rainbow.html. And while you are here in this site (choose English or Chinese), look at the more than 30 Java applets created by F.-K. Hwang at http://science.kongju.ac.kr/phys/shin/experiment/ntnujava/index.html. The interactive applet on Shadow/Image and Color is great fun, (http://science.kongju.ac.kr/phys/shin/experiment/ntnujava/shadow /shadow.html). From mixing colors, we can go to Thomas Chasteen's fine work at http://www.shsu.edu/~chm_tgc/sounds/sound.html for an animation (and movie also) of how to separate colors using a tuneable monochromator ( http://www.shsu.edu/~chemistry/monochromator/mono.gif). This colorful graphic, showing incoming parallel white light, is clipped from that monochromator animation. While you are here at this site at Sam Houston State University, look at the other great animations and movies, including a movie showing solution-phase chemiluminescence at http://www.shsu.edu/~chm_tgc/chemilumdir/movie.html. So now that we have explored the breaking down of light into its component colors, we need to also look at another process--polarizing light. Let's go to Science Media's comprehensive site ( http://www.scimedia.com/index.html#scimedia) to examine polarized light ( http://www.scimedia.com/chem-ed/spec/molec/polarim.htm). Of course, most sunglasses polarize light--bringing us back to the question of the rainbow again. Explore here for a while--appreciate the beautiful visible electromagnetic spectrum at http://www.scimedia.com/chem-ed/light/graphics/em-visib.jpg. Great spectroscopy tutorials from Brian Tissue of the Virginia Polytechnic Institute and State University are found at Science Media's site. One of my favorite graphics ( http://www.scimedia.com/chem-ed/light/graphics/em-rad.gif) reminds us of why light is electromagnetic radiation. But how to we actually see color? Go to the Access Excellence Classic Collection sponsored by Genentech, Inc. (http://www.gene.com/ae/AE/AEC/CC/).

  13. Web-MCQ: a set of methods and freely available open source code for administering online multiple choice question assessments.

    PubMed

    Hewson, Claire

    2007-08-01

    E-learning approaches have received increasing attention in recent years. Accordingly, a number of tools have become available to assist the nonexpert computer user in constructing and managing virtual learning environments, and implementing computer-based and/or online procedures to support pedagogy. Both commercial and free packages are now available, with new developments emerging periodically. Commercial products have the advantage of being comprehensive and reliable, but tend to require substantial financial investment and are not always transparent to use. They may also restrict pedagogical choices due to their predetermined ranges of functionality. With these issues in mind, several authors have argued for the pedagogical benefits of developing freely available, open source e-learning resources, which can be shared and further developed within a community of educational practitioners. The present paper supports this objective by presenting a set of methods, along with supporting freely available, downloadable, open source programming code, to allow administration of online multiple choice question assessments to students.

  16. VizieR Online Data Catalog: Swift/UVOT Serendipitous Source Catalog (Yershov, 2015)

    NASA Astrophysics Data System (ADS)

    Yershov, V. N.

    2015-11-01

    The first version of the Swift UVOT serendipitous source catalogue (UVOTSSC) provides positions and magnitudes, as well as errors and upper limits of confirmed sources for observations taken from start of operations in 2005 until October 1st of 2010. The first version of the Swift UVOT Serendipitous Source Catalogue (UVOTSSC) has been produced by processing the image data obtained from the Swift Ultraviolet and Optical Telescope (UVOT) from the beginning of the mission (2005) until 1st of October of 2010. The data processing was performed at the Mullard Space Science Laboratory (MSSL, University College London, U.K.) using Swift FTOOLS from NASA's High Energy Astrophysics Software (HEASoft-6.11), with some customising of the UVOT packages in order to get more complete source detection and properly apply quality flags to those sources that were detected within the UVOT image artefacts. The total number of observations with 17'x17' images used for version 1 of the catalogue is 23,059, giving 6,200,016 sources in total, of which 2,027,265 have multiple entries in the source table because they have been detected in more than one observation. Some sources were only observed in one filter. The total number of entries in the source table is 13,860,568. The S/N ratio for all sources exceeds 5 for at least one UVOT filter, the rest of the filters having a S/N greater than 3. (3 data files).

  19. Computational Models of Consumer Confidence from Large-Scale Online Attention Data: Crowd-Sourcing Econometrics

    PubMed Central

    2015-01-01

    Economies are instances of complex socio-technical systems that are shaped by the interactions of large numbers of individuals. The individual behavior and decision-making of consumer agents is determined by complex psychological dynamics that include their own assessment of present and future economic conditions as well as those of others, potentially leading to feedback loops that affect the macroscopic state of the economic system. We propose that the large-scale interactions of a nation's citizens with its online resources can reveal the complex dynamics of their collective psychology, including their assessment of future system states. Here we introduce a behavioral index of Chinese Consumer Confidence (C3I) that computationally relates large-scale online search behavior recorded by Google Trends data to the macroscopic variable of consumer confidence. Our results indicate that such computational indices may reveal the components and complex dynamics of consumer psychology as a collective socio-economic phenomenon, potentially leading to improved and more refined economic forecasting.

    2015-02-01

    As in Foylet et al (2013MNRAS.432.2182F), we use FIR maps to detect and extract the photometry of compact FIR-bright sources but also perform the photometry at the same source locations on MIR and Hα emission maps. In addition, we include a far-ultraviolet (FUV) map and gas maps (CO and HI) in order to trace young stellar populations bright in the UV and the cold gas possibly associated with the FIR sources. Here, we describe the data reduction prior to the source photometry. (2 data files).

  5. VizieR Online Data Catalog: Refined associations of Fermi/LAT sources (Massaro+, 2015)

    2015-04-01

    The Fermi-Large Area Telescope (LAT) First Source Catalog (1FGL) was released in 2010 February and the Fermi-LAT 2-Year Source Catalog (2FGL) appeared in 2012 April, based on data from 24 months of operation. Since they were released, many follow up observations of unidentified γ-ray sources have been performed and new procedures for associating γ-ray sources with potential counterparts at other wavelengths have been developed. Here we review and characterize all of the associations as published in the 1FGL and 2FGL catalogs on the basis of multifrequency archival observations. In particular, we located 177 spectra for the low-energy counterparts that were not listed in the previous Fermi catalogs, and in addition we present new spectroscopic observations of eight γ-ray blazar candidates. Based on our investigations, we introduce a new counterpart category of "candidate associations" and propose a refined classification for the candidate low-energy counterparts of the Fermi sources. We compare the 1FGL-assigned counterparts with those listed in 2FGL to determine which unassociated sources became associated in later releases of the Fermi catalogs. We also search for potential counterparts to all of the remaining unassociated Fermi sources. Finally, we prepare a refined and merged list of all of the associations of 1FGL plus 2FGL that includes 2219 unique Fermi objects. This is the most comprehensive and systematic study of all the associations collected for the γ-ray sources available to date. We conclude that 80% of the Fermi sources have at least one known plausible γ-ray emitter within their positional uncertainty regions. (2 data files).

    These catalogs are based on GALEX NUV and FUV source detections in and behind the Virgo Cluster. The detections are split into catalogs of extended sources and point-like sources. The UV Virgo Cluster Extended Source catalog (UV_VES.fit) provides the deepest and most extensive UV photometric data of extended galaxies in Virgo to date. If certain data is not available for a given source then a null value is entered (e.g. -999, -99). UV point-like sources are matched with SDSS, NGVS, and NED and the relevant photometry and further data from these databases/catalogs are provided in this compilation of catalogs. The primary GUViCS UV Virgo Cluster Point-Like Source catalog is UV_VPS.fit. This catalog provides the most useful GALEX pipeline NUV and FUV photometric parameters, and categorizes sources as stars, Virgo members, and background sources, when possible. It also provides identifiers for optical matches in the SDSS and NED, and indicates if a match exists in the NGVS, only if GUViCS-optical matches are one-to-one. NED spectroscopic redshifts are also listed for GUViCS-NED one-to-one matches. If certain data is not available for a given source a null value is entered. Additionally, the catalog is useful for quick access to optical data on one-to-one GUViCS-SDSS matches.The only parameter available in the catalog for UV sources that have multiple SDSS matches is the total number of multiple matches, i.e. SDSSNUMMTCHS. Multiple GUViCS sources matched to the same SDSS source are also flagged given a total number of matches, SDSSNUMMTCHS, of one. All other fields for multiple matches are set to a null value of -99. In order to obtain full optical SDSS data for multiply matched UV sources in both scenarios, the user can cross-correlate the GUViCS ID of the sources of interest with the full GUViCS-SDSS matched catalog in GUV_SDSS.fit. The GUViCS-SDSS matched catalog, GUV_SDSS.fit, provides the most relevant SDSS data on all GUViCS-SDSS matches, including one-to-one matches and multiply matched sources. The catalog gives full SDSS identification information, complete SDSS photometric measurements in multiple aperture types, and complete redshift information (photometric and spectroscopic). It is ideal for large statistical studies of galaxy populations at multiple wavelengths in the background of the Virgo Cluster. The catalog can also be used as a starting point to study and search for previously unknown UV-bright point-like objects within the Virgo Cluster. If certain data is not available for a given source that field is given a null value. (6 data files).

    The Midcourse Space Experiment (MSX) satellite mission included an astronomy experiment (SPIRIT III) designed to acquire mid-infrared photometry of sources in the Galactic plane (b<5°). MSX had a raw resolution of 18.3", a beam size 50 times smaller than that of IRAS at 12 and 25um. MSX observed six bands between 4 and 21um, of which the four between 8 and 21um are sensitive to astronomical sources. We used v2.3 of the MSX PSC (Egan et al. 2003, Cat. V/114) as our basic input, restricting ourselves to the main Galactic plane catalog, which excludes sources seen in only a single observing pass and those seen in multiple passes but with low significance. We restricted our catalog to 10source confusion, as well as kinematic distance ambiguities near the Galactic center. (2 data files).

    Using the powerful Earth-occultation technique, long-term, nearly continuous monitoring of the entire low-energy gamma-ray sky is now possible with the advent of BATSE, the Burst and Transient Source Experiment on board the Compton Gamma Ray Observatory (CGRO). In this paper, we present a catalog of 34 moderately strong gamma-ray sources measured by BATSE. It consists of 0.03 - 1.8 MeV photon spectra averaged over weeks and months, and light curves of the 35 - 200 keV flux, with 1 day resolution, covering the first three phases of the CGRO mission (1991 May through 1994 October). This database contains a complete record of {~}1200 daily source count rates in 14 energy channels along with the corresponding Poisson and systematic errors. (1 data file).

    This paper reports on novel separation methods developed for the direct determination of 14C in organic carbon (OC) and elemental carbon (EC), two sub-fractions of total carbon (TC) of atmospheric air particulate matter. Until recently, separation of OC and EC has been performed off-line by manual and time-consuming techniques that relied on the collection of massive CO2 fractions. We present here two on-line hyphenated techniques between a Sunset OC/EC analyzer and a MICADAS (MIni radioCArbon DAting System) accelerator mass spectrometer (AMS) equipped with a gas ion source. The first implementation facilitates the direct measurement in the low sample size range (<10 μg C) with high throughput on a routine basis, while the second explores the potential for a continuous-flow real-time CO2 gas feed into the ion source. The performance achieved with reference materials and real atmospheric samples will be discussed to draw conclusions on the improvement offered in the field of 14C aerosol source apportionment.

    2014-02-15

    A Resonance Ionization Laser Ion Source (RILIS) is today considered an essential component of the majority of Isotope Separator On Line (ISOL) facilities; there are seven laser ion sources currently operational at ISOL facilities worldwide and several more are under development. The ionization mechanism is a highly element selective multi-step resonance photo-absorption process that requires a specifically tailored laser configuration for each chemical element. For some isotopes, isomer selective ionization may even be achieved by exploiting the differences in hyperfine structures of an atomic transition for different nuclear spin states. For many radioactive ion beam experiments, laser resonance ionization is the only means of achieving an acceptable level of beam purity without compromising isotope yield. Furthermore, by performing element selection at the location of the ion source, the propagation of unwanted radioactivity downstream of the target assembly is reduced. Whilst advances in laser technology have improved the performance and reliability of laser ion sources and broadened the range of suitable commercially available laser systems, many recent developments have focused rather on the laser/atom interaction region in the quest for increased selectivity and/or improved spectral resolution. Much of the progress in this area has been achieved by decoupling the laser ionization from competing ionization processes through the use of a laser/atom interaction region that is physically separated from the target chamber. A new application of gas catcher laser ion source technology promises to expand the capabilities of projectile fragmentation facilities through the conversion of otherwise discarded reaction fragments into high-purity low-energy ion beams. A summary of recent RILIS developments and the current status of laser ion sources worldwide is presented.

    2013-06-01

    Polarimetric observations of our sample of 29 compact steep spectrum (CSS) sources were made at 8, 15 and 23GHz on August 6th, 1991 using the VLA in A-array. The observations were scheduled in "bracket" mode, i.e. calibrator-source-calibrator, to obtain the best possible phase correction. The data were recorded in both circular polarisations, and calibrated in the standard way using AIPS procedures. The sources 2200+420 (BLLac) and 0923+392 were observed regularly throughout the observing period to allow for parallactic angle corrections. Calibration of the Electric Vector Position Angle (EVPA) was performed by observing the source 1328+307 (3C286) assuming an EVPA of 33° for it at all frequencies. An iterative procedure was carried out using the IMAGR and CALIB programmes to self-calibrate the parallel-hand (LL or RR) fringes. The complex gain corrections derived in this way were also applied to the cross-hand (RL or LR) fringes. Images in Stokes parameters I, Q, and U were produced. Images of the polarised flux density P=(Q2+U2)0.5 and EVPA, chi=0.5xtan-1(U/Q), were then generated from the Q and U images. The data acquired with the 8GHz receiver were separately imaged for the two IFs, namely IF1 at 8085MHz and IF2 at 8485MHz, each having a bandwidth of 50MHz. (9 data files).

    The Midcourse Space Experiment (MSX) Ultraviolet Point Source Catalog contains 47,283 point sources from a set of 201 observations that surveyed approximately half the sky and from a set of 32 pointed observations toward specific targets. For each source, we provide position, UV magnitude and uncertainty in at least one of six filters and where possible an identification of a nearby source from the SIMBAD database. If a nearby source is identified, we include its proximity to the MSX source, and if known, the spectral type and the B and V magnitudes of the SIMBAD object. There were 11,565 matches between MSX and SIMBAD objects, and we estimate false identification to be about 3%. The limiting fluxes differ from filter to filter, and range from 10-16erg/s/cm2/{AA} for IUN4 to 7.8*10-12erg/s/cm2/{AA} for IUW3. Because of variations among the observation sets, the catalog is not complete to the limiting magnitudes for the filters. The UV instrument on MSX was named UVISI (Mill et al., 1994, Journal of Spacecraft and Rockets, 31, 900 (1994JSpRo..31..900M in ADS); Carbary et al., 1994, Applied Optics, 33, 4201 (1994ApOpt..33.4201C in ADS)). The fields-of-view for the narrow-field and wide-field UV imagers were 1.46x1.19deg (detector pixels of 20.6"x17.5") and 13.4x9.2deg (detector pixels of 3.12'x2.27'), respectively. Four filters were used with the narrow-field imager (IUN) with effective wavelengths centered at 2480{AA} (IUN3), 2310{AA} (IUN4), 2230{AA} (IUN5), and 2930{AA} (IUN6). Two filters were used with the wide-field imager (IUW) and centered at 1320{AA} (IUW3) and 1560{AA} (IUW6). Two data files are available for the MSX UV Point Source Catalog: the calibration data file and the catalog data file. (2 data files).

    There have been periodic electronic news media reports of potential bioterrorism-related incidents involving unknown substances (often referred to as “white powder”) since the 2001 intentional dissemination of Bacillus anthracis through the US Postal System. This study reviewed the number of unknown “white powder” incidents reported online by the electronic news media and compared them with unknown “white powder” incidents reported to the US Centers for Disease Control and Prevention (CDC) and the US Federal Bureau of Investigation (FBI) during a two-year period from June 1, 2009 and May 31, 2011. Results identified 297 electronic news media reports, 538 CDC reports, and 384 FBI reports of unknown “white powder.” This study showed different unknown “white powder” incidents captured by each of the three sources. However, the authors could not determine the public health implications of this discordance. PMID:25420771

    The INT/WFC Photometric H-Alpha Survey of the Northern Galactic Plane (IPHAS) is a 1860 deg^2 imaging survey of the Northern Milky Way at red visible wavelengths. It covers Galactic latitudes |b| < 5 deg and longitudes l = 30 to 215 deg in the broad-band r, i and narrow-band H-alpha filters using the Wide Field Camera (WFC) on the 2.5-m Isaac Newton Telescope (INT) in La Palma. IPHAS Data Release 2 (DR2) is the first quality-controlled and globally calibrated source catalogue derived from the survey, providing single-epoch photometry for 219 million unique sources across 92% of the footprint. The observations were carried out between 2003 and 2012 at a median seeing of 1.1 arcsec (sampled at 0.33 arcsec/pixel) and to a mean 5-sigma depth of 21.2 (r), 20.0 (i) and 20.3 (H-alpha). The photometric calibration is in the Vega magnitude system and carries an external precision of 0.03 mag (root-mean-square error). The catalogue includes all the sources which have been detected at a signal-to-noise ratio of 5 or better in at least one band. Many applications will require a combination of quality criteria to be applied to avoid faint stars or confused sources. The choice of quality criteria tensions completeness against reliability, and hence depends on the requirements of a project. To aid users, the data release paper (arXiv:1406.4862) recommends two sets of quality criteria, named "a10" and "a10point", which should satisfy most projects. As a minimum, the "a10" criteria select objects which have been detected at the minimum level of 10-sigma in all bands, without being saturated. Additional constraints are provided by the "a10point" criteria, which require objects to be point sources free of blending, unaffected by nearby bright stars, as well as being unsaturated >10-sigma detections in all bands. Sources in both categories are flagged in the catalogue using the boolean columns a10 and a10point. Imaging and auxiliary data are available from the project website (www.iphas.org). (1 data file).

    Table 2 lists the sources extracted with GAUSSCLUMPS from the filtered 870 micron continuum emission map of Chamaeleon I obtained with the bolometer camera LABOCA at the APEX telescope. These sources are listed in the order in which they were found by GAUSSCLUMPS, i.e. roughly in order of decreasing peak flux density. The 870 micron dust continuum emission map of the Chamaeleon I molecular cloud is available in FITS format. The data were obtained with the bolometer camera LABOCA at the APEX telescope. They were calibrated, reduced, co-added, gridded, smoothed to an effective angular resolution of 21.2" (FWHM), and written in FITS format with the BoA software. The flux density unit is Jy/21.2"-beam. The coordinates are equatorial (J2000) and the offsets are in RADIO projection. (6 data files).

    The catalogue consists of count rates and relative errors in three energy bands (total, 0.5-7keV; soft, 0.5-2keV; and hard, 2-7keV), and source positions relative to the highest signal-to-noise detection among the three bands. The wavelet algorithm also provides an estimate of the extension of the source. We include information drawn from the headers of the original files, as well, and extracted source counts in four additional energy bands, SB1 (0.5-1keV), SB2 (1-2keV), HB1 (2-4keV), and HB2 (4-7keV). We computed the sky coverage for the full catalogue and for a subset at high Galactic latitude (|b|>20deg). The complete catalogue provides a sky coverage in the soft band (0.5-2keV, S/N=3) of ~8deg2 at a limiting flux of 10-13erg/cm^2/s, and ~2deg2 at a limiting flux of ~10-15erg/cm^2/s. Furthermore, we present the results of the cross-match with existing catalogues at different wavelengths (FIRST, IRAS, 2MASS, GSC2, and ChaMP). The total numbers of matches with the FIRST, IRASPSC, 2MASS, and GSC2 catalogues obtained after a closest-distance selection are 13, 87, 6700, and 4485, respectively. (2 data files).

    2013-03-01

    Planck is a European Space Agency (ESA) mission, with significant contributions from the U.S. National Aeronautics and Space Agency (NASA). It is the third generation of space-based cosmic microwave background experiments, after the Cosmic Background Explorer (COBE) and the Wilkinson Microwave Anisotropy Probe (WMAP). Planck was launched on 14 May 2009 on an Ariane 5 rocket from Kourou, French Guiana. Following a cruise to the Earth-Sun L2 Lagrange point, cooling and in orbit checkout, Planck initiated the First Light Survey on 13 August 2009. Since then, Planck has been continuously measuring the intensity of the sky over a range of frequencies from 30 to 857GHz (wavelengths of 1cm to 350?m) with spatial resolutions ranging from about 33' to 5' respectively. The Low Frequency Instrument (LFI) on Planck provides temperature and polarization information using radiometers which operate between 30 and 70GHz. The High Frequency Instrument (HFI) uses pairs of polarization-sensitive bolometers at each of four frequencies between 100 and 353GHz but does not measure polarization information in the two upper HFI bands at 545 and 857GHz. The lowest frequencies overlap with WMAP, and the highest frequencies extend far into the submillimeter in order to improve separation between Galactic foregrounds and the cosmic microwave background (CMB). By extending to wavelengths longer than those at which the Infrared Astronomical Satellite (IRAS) operated, Planck is providing an unprecedented window into dust emission at far-infrared and submillimeter wavelengths. The PCCS (Planck Catalog of Compact Sources) is the list of sources detected in the first 15 months of Planck "nominal" mission. It consists of nine single-frequency catalogues of compact sources, both Galactic and extragalactic, detected over the entire sky. The PCCS covers the frequency range 30-857 GHz with higher sensitivity (it is 90% complete at 180mJy in the best channel) and better angular resolution than previous all-sky surveys in the microwave band. By construction its reliability is >80% and more than 65% of the sources have been detected at least in two contiguous Planck channels. Many of the Planck PCCS sources can be associated with stars with dust shells, stellar cores, radio galaxies, blazars, infrared luminous galaxies and Galactic interstellar medium features.

    The Astrophysics Source Code Library (ASCL)1 is a free online registry of codes used in astronomy research; it currently contains over 900 codes and is indexed by ADS. The ASCL has recently moved a new infrastructure into production. The new site provides a true database for the code entries and integrates the WordPress news and information pages and the discussion forum into one site. Previous capabilities are retained and permalinks to ascl.net continue to work. This improvement offers more functionality and flexibility than the previous site, is easier to maintain, and offers new possibilities for collaboration. This paper covers these recent changes to the ASCL.

  15. Photographs cause false memories for the news.

    What is the effect on memory when seemingly innocuous photos accompany false reports of the news? We asked people to read news headlines of world events, some of which were false. Half the headlines appeared with photographs that were tangentially related to the event; others were presented without photographs. People saw each headline only once, and indicated whether they remembered the event, knew about it, or neither. Photos led people to immediately and confidently remember false news events. Drawing on the Source Monitoring Framework (Johnson, Hashtroudi, & Lindsay, 1993), we suggest that people often relied on familiarity and other heuristic processes when making their judgments and thus experienced effects of the photos as evidence of memory for the headlines.

    We consider a sample of 883 radio sources detected at 1.4GHz in a deep Very Large Array (VLA) survey of the Extended Chandra Deep Field-South (E-CDFS) that reaches a best rms sensitivity of 6uJy. We used deep Spitzer InfraRed Array Camera (IRAC) and Multiband Imaging Photometer for Spitzer (MIPS) data. The IRAC data were obtained as part of the Spitzer IRAC/MUSYC Public Legacy Survey in the Extended CDF-South (SIMPLE) survey (Damen et al., 2011ApJ...727....1D, Cat. J/ApJ/727/1). It covers an area of about 1600 arcmin2 centred on the E-CDFS. The typical 5σ flux density limits are 1.1, 1.3, 6.3 and 7.6uJy at 3.6, 4.5, 5.8 and 8.0um, respectively. We also use MIPS 24um data from the Far-Infrared Deep Extragalactic Legacy (FIDEL) survey (Dickinson & FIDEL Team, 2007AAS...211.5216D). The E-CDFS has been mapped in the X-ray band by Chandra. A total of 129 radio sources have a counterpart in the 4 Ms observations of the CDFS presented in Xue et al. (2011ApJS..195...10X, Cat. J/ApJS/195/10) and another 99 in the main E-CDFS catalogue by Lehmer et al. (2005ApJS..161...21L, Cat. J/ApJS/161/21) obtained with shallower (250ks) observations in each of four pointings.

    Massive protostars have associated bipolar outflows that can produce strong shocks when they interact with the surrounding medium. At these shocks, particles can be accelerated up to relativistic energies. Relativistic electrons and protons can then produce gamma-ray emission, as some theoretical models predict. To identify young galactic objects that may emit gamma rays, we crossed the Fermi First Year Catalog with some catalogs of known massive young stellar objects (MYSOs), early type stars, and OB associations, and we implemented Monte Carlo simulations to find the probability of chance coincidences. We obtained a list of massive MYSOs that are spatially coincident with Fermi sources. (4 data files).

    In our observations, we used two non-dedicated instruments, shared by the Brazilian astronomical community: the 0.6m diameter Bollen & Chivens Cassegrain telescope (F/13.5, f=8.1m) and the 1.6m diameter Perkin-Elmer Cassegrain telescope (F/10, f=16m), located at the LNA observing site, the Observatorio do Pico dos Dias, Brasopolis, Brazil (OPD/LNA) (IAU code 874; λ=+45:34:57, φ=-22:32:04, h=1870m). We added sources for observation later on, with the outcome of the ICRF-ext1 (Ma, 2001, 15th Working Meeting on European VLBI for Geodesy and Astrometry) and of the ICRF-ext2 (Fey et al., 2008, Cat. J/AJ/127/3587). Naturally, not all sources could be observed, due to prohibitive telescope time consuming. When the ICRF2 was finally released in 2009, the program at OPD/LNA had already finished.

The High Frequency Instrument (HFI) uses pairs of polarization-sensitive bolometers at each of four frequencies between 100 and 353GHz but does not measure polarization information in the two upper HFI bands at 545 and 857GHz. The lowest frequencies overlap with WMAP, and the highest frequencies extend far into the submillimeter in order to improve separation between Galactic foregrounds and the cosmic microwave background (CMB). By extending to wavelengths longer than those at which the Infrared Astronomical Satellite (IRAS) operated, Planck is providing an unprecedented window into dust emission at far-infrared and submillimeter wavelengths. The Planck Early Release Compact Source Catalogue (ERCSC) is a list of all high reliability sources, both Galactic and extragalactic, derived from the first sky coverage. The data that went into this early release comprise all observations undertaken between 13 August 2009 and 6 June 2010, corresponding to Planck operational days 91-389. Since the Planck scan strategy results in the entire sky being observed every 6 months, the data considered in this release correspond to more than the first sky coverage. The source lists have reliability goals of >90% across the entire sky and >95% at high Galactic latitude. The goals on photometric accuracy are 30% while the positional accuracy goal translates to a positional root mean square (RMS) uncertainty that is less than 1/5 of the beam full width at half maximum (FWHM). Detailed explanations about the mission and the catalogs included here can be found in the "Explanatory supplement" (file "ercsc4_3.pdf"). Skymaps of the sources can be found in the "skymaps" subdirectory; postage stamps of the sources in the ECC (Early Cold Cores) catalog and in the different filters are located in the "stamps" subdirectory. The "Byte-by-byte Description" below contain column names standardized according to the conventions used at CDS; the original column names, as defined in the FITS files, are listed, enclosed within parentheses, at the end of the explanations.

    Mechanical systems could be severely damaged by loose debris generated through wear processes between contact surfaces. Hence, debris detection is necessary for effective fault diagnosis, life prediction, and prevention of catastrophic failures. This paper presents a new in-line debris sensor for hydraulic systems based on dual excitation sources. The proposed sensor makes magnetic lines more concentrated while at the same time improving magnetic field uniformity. As a result the sensor has higher sensitivity and improved precision. This paper develops the sensor model, discusses sensor structural features, and introduces a measurement method for debris size identification. Finally, experimental verification is presented indicating that that the sensor can effectively detect 81 μm (cube) or larger particles in 12 mm outside diameter (OD) organic glass pipe.

    The ATLBS radio images were made at 1388MHz using the Australia Telescope Compact Array (ATCA) by mosaic observing 38 adjacent pointing positions covering about 8.4deg2 of sky area. ATLBS images made with the synthesized beam of 50 arcsec were used as the basic resource for compiling the ATLBS-ESS sample. In the two, 2deg mosaic images, only "islands" of image pixels with peaks exceeding five times the image rms noise were considered. As described in Subrahmanyan et al. (2010, Cat. J/MNRAS/402/2792), the integrated flux density in compact components within these source islands were computed from images made with 4 arcsec FWHM beam using exclusively interferometer baselines to the 6km antenna. The ATLBS survey regions were also observed in optical g, r, and z band with the MOSAICII imager on the CTIO NOAO 4m Blanco telescope. (2 data files).

    Toxic cyanobacteria threaten the water quality of drinking water sources across the globe. Two such water bodies in Canada (a reservoir on the Yamaska River and a bay of Lake Champlain in Québec) were monitored using a YSI 6600 V2-4 (YSI, Yellow Springs, Ohio, USA) submersible multi-probe measuring in vivo phycocyanin (PC) and chlorophyll-a (Chl-a) fluorescence, pH, dissolved oxygen, conductivity, temperature, and turbidity in parallel. The linearity of the in vivo fluorescence PC and Chl-a probe measurements were validated in the laboratory with Microcystis aeruginosa (r(2) = 0.96 and r(2) = 0.82 respectively). Under environmental conditions, in vivo PC fluorescence was strongly correlated with extracted PC (r = 0.79) while in vivo Chl-a fluorescence had a weaker relationship with extracted Chl-a (r = 0.23). Multiple regression analysis revealed significant correlations between extracted Chl-a, extracted PC and cyanobacterial biovolume and in vivo fluorescence parameters measured by the sensors (i.e. turbidity and pH). This information will help water authorities select the in vivo parameters that are the most useful indicators for monitoring cyanobacteria. Despite highly toxic cyanobacterial bloom development 10 m from the drinking water treatment plant's (DWTP) intake on several sampling dates, low in vivo PC fluorescence, cyanobacterial biovolume, and microcystin concentrations were detected in the plant's untreated water. The reservoir's hydrodynamics appear to have prevented the transport of toxins and cells into the DWTP which would have deteriorated the water quality. The multi-probe readings and toxin analyses provided critical evidence that the DWTP's untreated water was unaffected by the toxic cyanobacterial blooms present in its source water. PMID:22159157

    The American public holds mixed views about the desirability of government action to combat childhood obesity. The framing of coverage by news media may affect citizens' views about the causes of childhood obesity and the most appropriate strategies for addressing the problem. We analyzed the content of a 20% random sample of news stories on childhood obesity published in 18 national and regional news sources in the United States over a 10-year period (2000-2009). News media coverage patterns indicated that by 2003, childhood obesity was firmly on the news media's agenda and remained so until 2007, after which coverage decreased. We identified changes in news media framing over time and significant differences according to news source. News coverage of causes of childhood obesity that were linked to the food and beverage industry increased in the early years of the study but then decreased markedly in later years. Similarly, mention of solutions to the problem of childhood obesity that involved restrictions on the food and beverage industry followed a reverse U-shaped pattern over the 10-year study period. News stories consistently mentioned individual behavioral changes most often as a solution to the problem of childhood obesity. Television news was more likely than other news sources to focus on behavior change as a solution, whereas newspapers were more likely to identify system-level solutions such as changes that would affect neighborhoods, schools, and the food and beverage industry.

  5. Do you want the good news or the bad news first? The nature and consequences of news order preferences.

    Information often comes as a mix of good and bad news, prompting the question, "Do you want the good news or the bad news first?" In such cases, news-givers and news-recipients differ in their concerns and considerations, thus creating an obstacle to ideal communication. In three studies, we examined order preferences of news-givers and news-recipients and the consequences of these preferences. Study 1 confirmed that news-givers and news-recipients differ in their news order preferences. Study 2 tested two solutions to close the preference gap between news-givers and recipients and found that both perspective-taking and priming emotion-protection goals shift news-givers' delivery patterns to the preferred order of news-recipients. Study 3 provided evidence that news order has consequences for recipients, such that opening with bad news (as recipients prefer) reduces worry, but this emotional benefit undermines motivation to change behavior.

    Combining far-infrared Herschel photometry from the PACS Evolutionary Probe (PEP) and Herschel Multi-tiered Extragalactic Survey (HerMES) guaranteed time programs with ancillary datasets in the GOODS-N, GOODS-S and COSMOS fields, it is possible to sample the 8-500 micron spectral energy distributions of galaxies with at least 7-10 bands. Extending to the UV, optical, and near- infrared, the number of bands increases up to 43. We reproduce the distribution of galaxies in a carefully selected 10 restframe color space, based on this rich data-set, using a superposition of multi-variate Gaussian modes. We use this model to classify galaxies and build median spectral energy distributions (SEDs) of each class, which are then fitted with a modified version of the MAGPHYS code that combines stellar light, emission from dust heated by stars and a possible warm dust contribution heated by an Active Galactic Nucleus (AGN). The color distribution of galaxies in each of the considered fields can be well described with the combination of 6-9 classes, spanning a large range of far- to near-IR luminosity ratios, as well as different strength of the AGN contribution to bolometric luminosities. The defined Gaussian grouping is used to identify rare or odd sources. The zoology of outliers includes Herschel-detected ellipticals, very blue z~1 Lyα-break galaxies, quiescent spirals, and torus-dominated AGN with star formation. Out of these groups and outliers, a new template library is assembled, consisting of 32 SEDs describing the intrinsic scatter in the restframe UV-to-submm colors of infrared galaxies. This library is tested against L(IR) estimates with and without Herschel data included, and compared to eight other popular methods often adopted in the literature. When implementing Herschel photometry, these approaches produce L(IR) values consistent with each other within a median absolute deviation of 10-20%, the scatter being dominated more by fine tuning of the codes, rather than by the choice of SED templates. Finally, the library is used to classify 24 micron detected sources in PEP GOODS fields on the basis of AGN content, L(60)/L(100) color and L(160)/L(1.6) luminosity ratio. AGN appear to be distributed in M*-SFR along with all other galaxies, regardless of the amount of infrared luminosity they are powering, with the tendency to lie on the high SFR side of the "main sequence". The incidence of warmer star-forming sources grows for objects with higher specific star formation rates, and they tend to populate the "off-sequence" region of the M*-SFR-z space. (4 data files).

    The 20cm radio data come from the Unified Radio Catalog (URC) compiled by Kimball & Ivezic (2008AJ....136..684K). This radio catalogue combines data from the National Radio Astronomy Observatory (NRAO) VLA Sky Survey (NVSS; Condon et al., 1998, Cat. VIII/65), Faint Images of the Radio Sky at Twenty Centimeters (FIRST; Becker, White & Helfand, 1995, cat. VIII/92), Green Bank 6cm survey (GB6; Gregory et al., 1996, Cat.

    In the E-CDF-S area, we have two sets of X-ray data obtained with Chandra. The most important is a 4-Ms exposure observation resulting from the co-addition of 54 individual Chandra ACIS-I exposures from 1999 October to 2010 July, with centres spaced within a few arcseconds from RA=03:32:28.80, DE=-27:48:23 (J2000). We consider the data from the new VLA programme which provides deep, high-resolution 1.4-GHz imaging across the full E-CDF-S, consisting of a six-pointing mosaic of 240 h spanning 48 d of individual 5-h observations (Miller et al., 2008, Cat.

    With computers and the World Wide Web widely available, collecting data through Web browsers is an attractive method utilized by the social sciences. In this article, conducting PC- and Web-based trials with the software package dynQuest is described. The software manages dynamic questionnaire-based trials over the Internet or on single computers, possibly as randomized control trials (RCT), if two or more groups are involved. The choice of follow-up questions can depend on previous responses, as needed for matched interventions. Data are collected in a simple text-based database that can be imported easily into other programs for postprocessing and statistical analysis. The software consists of platform-independent scripts written in the programming language PERL that use the common gateway interface between Web browser and server for submission of data through HTML forms. Advantages of dynQuest are parsimony, simplicity in use and installation, transparency, and reliability. The program is available as open-source freeware from the authors. PMID:17958153

    Most of the sources are south of the celestial equator and have been classified in increasing galactic longitude over the period Sept. 1985 to May 1992. They have been classified on Kodak I-N objective-prism plates taken primarily with the Curtis Schmidt telescope at Cerro Tololo, but some northern plates taken with the Burrell Schmidt at Kitt Peak were also used for classification. The spectra cover the range 680-880nm at a dispersion of 340nm/mm at the A-band, and the plate scale is 96.6"/mm. They are ideal for classifying M stars of type M3 and cooler (increasing strength of TiO and VO bands) and carbon stars (CN bands), but stars warmer than M2 and most S stars cannot be classified or identified as such. The M stars M3 and cooler can be separated into about five groups. The limiting mag of the deepest plates is I about 13.5. The IRAS PS were identified on transparent overlays made to the plate scale for each plate center, and the association of a spectrum with a given PS is usually unambiguous. In cases of doubt or offset, a comment is made. Note that there are some cases where the PSC gives an incorrect association on the basis of position, and the correct association is with a faint, uncatalogued M star. (3 data files).

  15. Perplexity Analysis of Obesity News Coverage

    2009-01-01

    An important task performed during the analysis of health news coverage is the identification of news articles that are related to a specific health topic (e.g. obesity). This is often done using a combination of keyword searching and manual encoding of news content. Statistical language models and their evaluation metric, perplexity, may help to automate this task. A perplexity study of obesity news was performed to evaluate perplexity as a measure of the similarity of news corpora to obesity news content. The results of this study showed that perplexity increased as news coverage became more general relative to obesity news (obesity news ≈ 187, general health news ≈ 278, general news ≈ 378, general news across multiple publishers ≈ 382). This indicates that language model perplexity can measure the similarity news content to obesity news coverage, and could be used as the basis for an automated health news classifier. PMID:20351893

    The presence of dissolved metal ions in waters associated with crude oils has many negative implications for the transport, processing, and refining of petroleum. In addition, mass spectrometric analysis of sodium containing crude oil samples suffers from ionization suppression, unwanted adduct formation, and an increase in the complexity of data analysis. Here, we describe a method for the reduction/elimination of these adverse effects by modification of the source region gas-inlet system of a 12 T Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. Several acids were examined as part of this study, with the most suitable for on-line desalting found to have both high vapor pressure and low pK(a); 12.1 M HCl showed the strongest desalting effect for crude oil samples with a sodium removal index (SRI) of 88%-100% ± 7% for the NaOS compound class. In comparison, a SRI of only 38% ± 9% was observed for a H₂O/toluene solution-phase extraction of oil 1. These results clearly demonstrate the increased efficacy of pseudo-vapor phase desalting with the additional advantages that initial sample solution conditions are preserved and no sample preparation is required prior to analysis.

  17. Sources of information influencing decision-making in orthopaedic surgery - an international online survey of 1147 orthopaedic surgeons

    PubMed Central

    2013-01-01

    Background Manufacturers of implants and materials in the field of orthopaedics use significant amounts of funding to produce informational material to influence the decision-making process of orthopaedic surgeons with regards to choice between novel implants and techniques. It remains unclear how far orthopaedic surgeons are really influenced by the materials supplied by companies or whether other, evidence-based publications have a higher impact on their decision-making. The objective was to evaluate the subjective usefulness and usage of different sources of information upon which orthopaedic surgeons base their decisions when acquiring new implants or techniques. Methods We undertook an online survey of 1174 orthopaedic surgeons worldwide (of whom n = 305 were head of their department). The questionnaire included 34 items. Sequences were randomized to reduce possible bias. Questions were closed or semi-open with single or multiple answers. The usage and relevance of different sources of information when learning about and selecting orthopaedic treatments were evaluated. Orthopaedic surgeons and trainees were targeted, and were only allowed to respond once over a period of two weeks. Baseline information included country of workplace, level of experience and orthopaedic subspecialisation. The results were statistically evaluated. Results Independent scientific proof had the highest influence on decisions for treatment while OEM (Original Equipment Manufacturer) driven activities like newsletters, white papers or workshops had the least impact. Comparison of answers from the three best-represented countries in this study (Germany, UK and USA) showed some significant differences: Scientific literature and congresses are significantly more important in the US than in the UK or Germany, although they are very important in all countries. Conclusions Independent and peer-reviewed sources of information are preferred by surgeons when choosing between methods and implants. Manufacturers of medical devices in orthopaedics employ a considerable workforce to inform or influence hospital managers and leading doctors with marketing activities. Our results indicate that it might be far more effective to channel at least some of these funds into peer-reviewed research projects, thereby assuring significantly higher acceptance of the related products.

  18. The persuasion context and results in online opinion seeking: effects of message and source-the moderating role of network managers.

    2013-11-01

    Online opinion networks are areas for social exchange, or conversational networks, made up of individuals actively involved in sharing experiences and opinions concerning matters of mutual interest between consumers or concerning their experience with a given product or service. We pinpoint a gap in the literature regarding how the persuasion process occurs when individuals seek opinions online, including the results process. In an attempt to find an answer, we draw on traditional theories related to information processing. These are mostly taken from the field of psychology and enable us to identify which signals or aspects of communication or opinions the individuals focus their attention on (message and source) and the value attached to such communications as well as how much they impact individuals' purchase decisions, bearing in mind the medium (or online opinion network) in which the opinions are located. Findings from those interviewed support the idea that the quality of information on the Internet, as well as trust in the source of said information, or in the opinion of network users, have an impact on the informational value obtained from involvement in this online opinion seeking and on purchasing decisions. Moreover, depending on the kind of network (firm or brand controlled, review Web sites, and user-controlled nonofficial opinion networks), the quality of the information or trust in the users will have a different bearing in the persuasion process.

    In this paper, we present a schema for content-based analysis of broadcast news video. First, we separate commercials from news using audiovisual features. Then, we automatically organize news programs into a content hierarchy at various levels of abstraction via effective integration of video, audio, and text data available from the news programs. Based on these news video structure and content analysis technologies, a TV news video Library is generated, from which users can retrieve definite news story according to their demands.

    There have been periodic electronic news media reports of potential bioterrorism-related incidents involving unknown substances (often referred to as "white powder") since the 2001 intentional dissemination of Bacillus anthracis through the U.S. Postal System. This study reviewed the number of unknown "white powder" incidents reported online by the electronic news media and compared them with unknown "white powder" incidents reported to the U.S. Centers for Disease Control and Prevention (CDC) and the U.S. Federal Bureau of Investigation (FBI) during a 2-year period from June 1, 2009 and May 31, 2011. Results identified 297 electronic news media reports, 538 CDC reports, and 384 FBI reports of unknown "white powder." This study showed different unknown "white powder" incidents captured by each of the three sources. However, the authors could not determine the public health implications of this discordance.

  3. Contact: Releasing the news

    NASA Astrophysics Data System (ADS)

    Pinotti, Roberto

    The problem of mass behavior after man's future contacts with other intelligences in the universe is not only a challenge for social scientists and political leaders all over the world, but also a cultural time bomb as well. In fact, since the impact of CETI (Contact with Extraterrestrial Intelligence) on human civilization, with its different cultures, might cause a serious socio-anthropological shock, a common and predetermined worldwide strategy is necessary in releasing the news after the contact, in order to keep possible manifestations of fear, panic and hysteria under control. An analysis of past studies in this field and of parallel historical situations as analogs suggests a definite "authority crisis" in the public as a direct consequence of an unexpected release of the news, involving a devastating "chain reaction" process (from both the psychological and sociological viewpoints) of anomie and maybe the collapse of today's society. The only way to prevent all this is to prepare the world's public opinion concerning contact before releasing the news, and to develop a long-term strategy through the combined efforts of scientists, political leaders, intelligence agencies and the mass media, in order to create the cultural conditions in which a confrontation with ETI won't affect mankind in a traumatic way. Definite roles and tasks in this multi-level model are suggested.

    An in-source, stretched, hollow fiber membrane (HFM) inlet has been developed to improve the sensitivity of on-line time-of-flight mass spectrometry (TOFMS) with a vacuum ultraviolet (VUV) lamp based single photon ionization (SPI) source for the direct analysis of liquid samples. A 2-cm HFM was stretched to 8 cm in length, and placed in the ion source and directly under the VUV lamp window with a distance of 15 mm. Compared with the conventional flow-through configuration under the same experimental conditions, the signal intensities of selected volatile organic compounds (VOCs) of methyl tert-butyl ether (MTBE), ethyl tert-butyl ether (ETBE), benzene, toluene and p-xylene were increased over 5-fold in magnitude, and the response time was shortened to one-third. The limits of detection (LOD) of MTBE, ETBE, benzene, toluene and p-xylene ranged from 0.25 to 1.3 μg L(-1) with a measurement time of 60 s, and three orders of linear range were obtained with correlation coefficients of 0.9972-0.9992. The present results suggest that the in-source stretched HFM is a simple and effective way to increase the sensitivity and shorten response time of the membrane inlet, and we believe that it will also be beneficial to other types of on-line mass spectrometer for the on-line analysis of VOCs in water with a VUV lamp based SPI ion source.

  5. SciNews: Incorporating Science Current Events in 21st Century Classrooms

    NASA Astrophysics Data System (ADS)

    DiMaggio, E.

    2011-12-01

    Middle school students are instructed with the aid of textbooks, lectures, and activities to teach topics that satisfy state standards. However, teaching materials created to convey standard-aligned science concepts often leave students asking how the content relates to their lives and why they should be learning it. Conveying relevance is important for student learning and retention, especially in science where abstract concepts can often be incorrectly perceived as irrelevant. One way to create an educational link between classroom content and everyday life is through the use of scientific current events. Students read, hear, and watch media coverage of natural events (such as the 2011 earthquake and tsunami in Japan), but do not necessarily relate the scientific information from media sources to classroom studies. Taking advantage of these brief 'teachable moments'--when student interest is high--provides a valuable opportunity to make classroom-to-everyday life associations and to incorporate inquiry based learning. To address this need, I create pre-packaged current event materials for middle to high school teachers that align to state standards, and which are short, effective, and easy to implement in the classroom. Each lesson takes approximately 15-30 minutes to implement, allowing teachers time to facilitate brief but meaningful discussions. I assemble materials within approximately one week of the regional or global science event, consisting of short slide shows, maps, videos, pictures, and real-time data. I use a listserv to send biweekly emails to subscribed instructors containing the current event topic and a link to download the materials. All materials are hosted on the Arizona State University Education Outreach SciNews website (http://sese.asu.edu/teacher-resources) and are archived. Currently, 285 educators subscribe to the SciNews listserv, representing 36 states and 19 countries. In order to assess the effectiveness and usefulness of SciNews materials, each lesson links to a brief online survey. I ask educators for basic information (grade level, number of students) as well as feedback on lesson content, accessibility of media types used, agreement with standards, and general comments on how to improve SciNews. Survey results show that SciNews lessons have been implemented in elementary through college classrooms. Comments express an overall agreement that Scinews lessons facilitate classroom discussion, heighten student interest in the topic, and that lessons are easy to use and modify. Current events help demonstrate to students that, unlike fact-filled textbooks suggest, science is not static and scientists are actively investigating many 'textbook' concepts. Showing students the process and progressive nature of scientific information reinforces critical thinking rather than pure memorization.

    Provider-patient communication is an important factor influencing patients' satisfaction and health outcomes. This study draws upon the uses and gratification theory to examine how individuals' perception of communication with healthcare providers is associated with their Internet use for health-related activities. Using the data from the 2007 Health Information National Trends Survey (HINTS), we found that as individuals perceived their communication with providers to be less patient-centered, they were more likely to engage in various types of online health activities, such as using websites for healthy lifestyles, searching for healthcare providers, and seeking health information. Trust in online health information was also found to be a significant predictor of online health activities. The results of this study emphasized the important role of provider-patient communication in motivating individuals to turn to the Internet for health purposes. PMID:21154093

    Objective To characterise the relative amount and type of daily newspaper, local and national TV newscast, and national news magazine coverage of tobacco control issues in the United States in 2002 and 2003. Design Content analysis of daily newspapers, news magazines, and TV newscasts. Subjects Items about tobacco in daily newspapers, local and national TV newscasts, and three national news magazines in a nationally representative sample of 56 days of news stratified by day of week and season of the year, from 2002 and 2003. Main outcome measures Story theme, tobacco topics, sources, story prominence, story valence (orientation), and story type. Results Tobacco coverage was modest over the two‐year period as estimated in our sample. Only 21 TV stories, 17 news magazine stories, and 335 daily newspaper stories were found during the two‐year sampling period. Noteworthy results for the newspaper data set include the following: (1) government topics predominated coverage; (2) government action and negative health effects topics tended not to occur together in stories; (3) tobacco stories were fairly prominently placed in newspapers; (4) opinion news items tended to favour tobacco control policies, while news and feature stories were evenly split between positive and negative stories; and (5) tobacco coverage in the southeast, which is the country's major tobacco producing region, did not differ from the rest of the country. Conclusion Results suggest mixed support in news coverage for tobacco control efforts in the United States. The modest amount of news coverage of tobacco is troubling, particularly because so few news stories were found on TV, which is a more important news source for Americans than newspapers. When tobacco was covered, government themed stories, which often did not include mentions of negative health effects, were typical, suggesting that media coverage does not reinforce the reason for tobacco control efforts. However, some results were encouraging. For example, when newspapers did cover tobacco, they accorded the stories relatively high prominence, thus increasing the chance that readers would see tobacco stories when they were published.

  10. A qualitative study of the coverage of influenza vaccination on Dutch news sites and social media websites

    PubMed Central

    2013-01-01

    Background Information about influenza and the effectiveness of vaccination against influenza is largely available on the Internet, and may influence individual decision making about participation in future influenza vaccination rounds. E-health information has often been found to be inaccurate, or even to contradict Health Authority recommendations, especially when it concerns controversial topics. Methods By means of an online media monitoring programme, Dutch news sites and social media websites were scanned for the Dutch counterparts of the terms influenza, vaccination, vaccine and epidemic during February, March and April 2012. Data were processed with QSR NVivo 8.0 and analysed using a general inductive approach. Results Three overarching themes were found in both media sources: (1) the (upcoming) influenza epidemic, (2) general information regarding the virus, its prevention and treatment, and (3) uncertainty and mistrust regarding influenza vaccination. Social media tended to report earlier on developments such as the occurrence of an influenza epidemic. The greatest difference was that in social media, influenza was not considered to be a serious disease, and more opposition to the flu shot was expressed in social media, as compared to news media. Conclusions News media and social media discussed the same topics regarding influenza, but differed in message tone. Whereas news media reports tended to be more objective and non-judgmental, social media more critically evaluated the harmfulness of influenza and the necessity of the flu shot. Media may influence decision making and behaviours of Internet users and may thereby influence the success of vaccination campaigns and recommendations made by health authorities. Social media may be more of a problem in this sense, since it is neither controlled nor censored. Future research should investigate the actual impact of Internet media on the influenza decision making process of its users. PMID:23738769

Results showed that the first pandemic was frequently framed with the medical/scientific and political/legal issues, while the second pandemic was emphasized with the health risk issue in TV news. Both flu pandemics were regularly reported with mortality exemplars, but the focus in the first pandemic was on the flu virus threat and vaccination side effects, while the vaccination shortage was frequently revealed in the second outbreak.

    Supplementary Materials The number of supplementary materials that accompany print articles has grown and also become more varied. The new guidelines for lab experiments call for supplementary materials in most cases, so that the actual materials used in lab can be made available. The From Past Issues column edited by Kathryn Williams and many of the technology columns frequently have supplements for JCE Online. An especially interesting supplement that we would like to call to the attention of readers is a collection of videos from the E. O. Lawrence Berkeley National Laboratory, based on interviews with nuclear chemists who have discovered and studied the heaviest elements. These movies accompany the Viewpoints article, "Chemistry of the Heaviest Elements-One Atom at a Time" by Darleane C. Hoffman and Diana M. Lee. The titles of the movies are listed below; illustrative stills are shown at the bottom of the page. Researchers involved with the segments about Lawrencium include Robert Silva, Torbjorn Sikkeland, Matti Nurmia, Robert Latimer, and Albert Ghiorso, all of whom are from the Lawrence Berkeley Laboratory. (QuickTime 3 is needed in order to view the videos; it can be downloaded free from http://www.apple.com.)

People: Glenn Seaborg Glenn Seaborg, frequent contributor and faithful supporter of this Journal, died February 25, 1999, at his home in Lafayette, California, at the age of 86. At the Fall 1998 ACS Meeting in Boston he suffered a serious fall following a stroke, from which he never recovered. One of his last photographs, taken the previous day at a Journal luncheon, appears on page 1360 of the November 1998 issue. His commentary on his long career in chemistry and education appears on page 1520 of the December 1998 issue. Seaborg was a Nobel laureate, discoverer of elements, scientific advisor to presidents, former chancellor of the University of California, former chairman of the Atomic Energy Commission, chairman of the steering committee of the CHEM Study project, founder of Lawrence Hall of Science, , the list goes on and on. He was at the same time a passionate supporter of education. Seaborg published fourteen articles in the Journal between 1951 and 1998. He was interviewed in 1975 by David Ridgway as part of the Impact series (JCE 1975, 52, 70), and that interview is highly recommended reading (see supplement to this article). He received the 1994 ACS George C. Pimentel Award in Chemical Education; his award address was published in the ACS Division of Chemical Education's CHED Newsletter, Fall 1995. Memorial articles with details of his life and his scientific contributions have appeared in The New York Times (Saturday, February 27, 1999, page 1) and Chemical & Engineering News (March 8, 1999, page 29). But there is also the spirit of the man, what he believed in, what he tried to do, what he hoped he had accomplished. A sense of that can be gained from the excerpts that are reprinted below, taken first from the Impact interview and then from the award address. Ridgway: On reflection, now, out of your many contributions to chemistry, is there one that you feel has had more of an impact than others? Seaborg: The discovery of plutonium would answer that question. The impact there is probably nearly as great as any single chemical discovery. Ridgway: What was the state of the "art" in your field when you first decided to bend your energies in this direction? Seaborg: In nuclear science? Very crude. I mean we had difficulty even making the simplest Geiger counter work. This facet alone was always a challenge. Ridgway: What do you look for in a young person who wishes to work with you in your research program? Seaborg: Certainly I try to identify intelligence and creativity and very importantly, industry, that is the willingness to work hard which leads to dedication. Ridgway: ...research and teaching or research versus teaching. Do you consider in your own pursuits in the academic life a dichotomy between teaching and research? Seaborg: Definitely not! I think they go together very well. I teach freshman chemistry and it's a joy to meet my freshman chemistry sections. It gives me a better perspective even though it's at the beginning level. In addition, the fact that I'm conducting research helps (in my opinion) freshman chemistry. As your readers well know, freshman chemistry is a sophisticated and complicated subject these days. Pimentel Award Address: Regarding the CHEM Study project: Although my heavy schedule as Chancellor of the University of California, Berkeley, and numerous other commitments should have made me decline this added responsibility, the unusual circumstances of our meeting and the ardor of the group led to my somewhat bewildered acceptance. Report of the National Commission on Excellence in Education (1983): If an unfriendly foreign power had attempted to impose on America the mediocre educational performance that exists today, we might well have viewed it as an act of war. As it stands, We have allowed this to happen to ourselves Discussing Great Explorations in Math and Science (GEMS): It is an unfortunate fact, borne out by research and much anecdotal experience, that by the time they reach high school most students have already decided whether or not they like chemistry, and whether or not they are good at it. In Summary: Having served in many capacities, educational and governmental over my career, I have no illusions about the complexities involved in implementing change. Yet there is really no choice if we are to survive and thrive as a nation. We must shine a strong spotlight on education, with special and lasting emphasis on science and technology, and the real-world connections so apparent to us in chemistry and all the sciences.

  7. Databases toward Disseminated Use - Nikkei News Telecom -

    NASA Astrophysics Data System (ADS)

    Kasiwagi, Akira

    The need for “searchers” - adept hands in the art of information retrieval - is increasing nowadays. Searchers have become necessary as the result of the upbeat online database market. The number of database users is rising steeply. There is the urgent need to develop potential users of general information, such as newspaper articles. Simple commands, easy operation, and low prices hold the key to general popularization of databases, and the issue lies in how the industry will get about achieving this task. Nihon Keizai Shimbun has been undertaking a wide range of possibilities with Nikkei News Telecom. Although only two years have passed since its start, results of Nikkei’s efforts are summarized below.

  8. Exploring women's responses to online media coverage of weight loss surgery.

    Champion, C; Glenn, N; Berry, T; Spence, J C

    2015-10-01

    The purpose of this study was to understand the reactions of women to online news articles about weight loss surgery and related reader comments. Focus groups were conducted; open-ended questions were asked to elicit responses to existing online news media content related to weight loss surgery. The participants described the online articles as predominantly supportive of weight loss surgery and in response they expressed a desire to see more critical content, including different and competing perspectives. Participants felt the online comments represented extreme perspectives and were predominately negative. These were therefore not viewed as helpful or informative. Nevertheless, readers viewed comments as a form of entertainment. Because of the aggressive and anonymous nature of reader comments in response to online news stories, the participants did not feel comfortable leaving comments themselves on the news sites. Findings highlight the importance of gathering readers' perspectives in response to interactive media content and, in particular, health information. PMID:26278398

  16. [The making of AIDS news].

    PubMed

    Spink, M J; Medrado, B; Menegon, V M; Lyra, J; Lima, H

    2001-01-01

    This study is part of the overall research effort on the role of the media in making sense of events in late modernity. The main objective is to investigate the context in which news about AIDS is produced at the interface between norms for producing news (as expressed by professional journalists) and an analysis of news stories published in four mainstream Brazilian newspapers. The results are organized in three broad topics: (a) the construction of news about AIDS; (b) the visibility of AIDS news during the study period; and (c) factors that facilitate or hinder the production of AIDS news. Important factors include exclusiveness of the story and/or novelty of the content, the notion of hot (or cold) news, and the specific contents. The authors also emphasize the inevitable chance elements associated with organizational characteristics and daily journalism. They conclude by pointing to recent changes in both the shape of the AIDS epidemic and the communications dynamics resulting from recent developments in the electronic media. PMID:11514866

    Radioactive ion beams (RIB) have been produced on-line, using a gas-jet recoil transport coupled Electron Cyclotron Resonance (ECR) ion-source at the VECC-RIB facility. Radioactive atoms/molecules carried through the gas-jet were stopped in a catcher placed inside the ECR plasma chamber. A skimmer has been used to remove bulk of the carrier gas at the ECR entrance. The diffusion of atoms/molecules through the catcher has been verified off-line using stable isotopes and on-line through transmission of radioactive reaction products. Beams of {sup 14}O (71 s), {sup 42}K (12.4 h), {sup 43}K (22.2 h), and {sup 41}Ar (1.8 h) have been produced by bombarding nitrogen and argon gas targets with proton and alpha particle beams from the K130 cyclotron at VECC. Typical measured intensity of RIB at the separator focal plane is found to be a few times 10{sup 3} particles per second (pps). About 3.2 Multiplication-Sign 10{sup 3} pps of 1.4 MeV {sup 14}O RIB has been measured after acceleration through a radiofrequency quadrupole linac. The details of the gas-jet coupled ECR ion-source and RIB production experiments are presented along with the plans for the future.

  20. Dangerous news: media decision making about climate change risk.

    PubMed

    Smith, Joe

    2005-12-01

    This article explores the role of broadcast news media decision makers in shaping public understanding and debate of climate change risks. It locates the media within a "tangled web" of communication and debate between sources, media, and publics. The article draws on new qualitative research in the British context. The main body of it focuses on media source strategies, on climate change storytelling in news, and the "myth of detachment" sustained by many news decision makers. The empirical evidence, gathered between 1997 and 2004, is derived primarily from recordings and notes drawn from a series of seminars that has brought together equal numbers of BBC news and television decision makers and environment/development specialists. The seminars have created a rare space for extended dialogue between media and specialist perspectives on the communication of complex climate change science and policy. While the article acknowledges the distinctive nature of the BBC as a public sector broadcaster, the evidence confirms and extends current understanding of the career of climate change within the media more broadly. The working group discussions have explored issues arising out of how stories are sourced and, in the context of competitive and time-pressured newsrooms, shaped and presented in short news pieces. Particularly significant is the disjuncture between ways of talking about uncertainty within science and policy discourse and media constructions of objectivity, truth, and balance. The article concludes with a summary of developments in media culture, technology, and practice that are creating opportunities for enhanced public understanding and debate of climate change risks. It also indicates the need for science and policy communities to be more active critics and sources of news. PMID:16506976

    We demonstrate a multimodal optical coherence tomography (OCT) and online Fourier transform coherent anti-Stokes Raman scattering (FTCARS) platform using a single sub-12 femtosecond (fs) Ti:sapphire laser enabling simultaneous extraction of structural and chemical ("morphomolecular") information of biological samples. Spectral domain OCT prescreens the specimen providing a fast ultrahigh (4×12  μm axial and transverse) resolution wide field morphologic overview. Additional complementary intrinsic molecular information is obtained by zooming into regions of interest for fast label-free chemical mapping with online FTCARS spectroscopy. Background-free CARS is based on a Michelson interferometer in combination with a highly linear piezo stage, which allows for quick point-to-point extraction of CARS spectra in the fingerprint region in less than 125 ms with a resolution better than 4  cm(-1) without the need for averaging. OCT morphology and CARS spectral maps indicating phosphate and carbonate bond vibrations from human bone samples are extracted to demonstrate the performance of this hybrid imaging platform.

    Between 1997 June and 2001 February the Two Micron All Sky Survey (2MASS) collected 25.4 Tbytes of raw imaging data covering 99.998% of the celestial sphere in the near-infrared J(1.25{mu}m), H(1.65{mu}m), and Ks(2.16{mu}m) bandpasses. Observations were conducted from two dedicated 1.3 m diameter telescopes located at Mount Hopkins, Arizona, and Cerro Tololo, Chile. The 2MASS All-Sky Data Release includes the FITS images covering the entire sky, a Point Source Catalog (PSC) of 471 million sources (Cat. II/242), and the present Extended Source Catalog. The 2MASS Extended Source Catalog contains sources that are extended with respect to the instantaneous PSF, such as galaxies and Galactic nebulae. The algorithms used to create the 2MASX catalog are described by Jarett et al. (2000AJ....119.2498J), and in the 2MASS Explanatory Supplement (accessible from the 2MASS Home Page). Briefly, point/ extended-source discrimination was conducted for each band-merged point-source detection by comparing a variety of radial shape, surface brightness, image moments, and symmetry parameters with characteristic stellar parameters using an oblique decision tree classifier. The classification tests included filters to exclude double and triple stars, which were one of the main contaminants in high source density regions. Stellar parameters were measured empirically as a function of time in each scan to compensate for variations in the atmospheric seeing using the aggregate properties of band-merged point-source extractions. The catalog contains 389 columns described briefly in the "Byte-by-byte Description" section below; their description includes also the 2MASS database original column names used in the original descriptions.

    Laser ion sources based on resonant excitation and ionization of atoms are well-established tools for selective and efficient production of radioactive ion beams. A recent trend is the complementary installation of reliable state-of-theart all solid-state Ti:Sapphire laser systems. To date, 35 elements of the Periodic Table are available at laser ion sources by using these novel laser systems, which complements the overall accessibility to 54 elements including use of traditional dye lasers. Recent progress in the field concerns the identification of suitable optical excitation schemes for Ti:Sapphire laser excitation as well as technical developments of the source in respect to geometry, cavity material as well as by incorporation of an ion guide system in the form of the laser ion source trap LIST.

    OBJECTIVES: This study explores how local television news structures the public and policy debate on youth violence. METHODS: A content analysis was performed on 214 hours of local television news from California. Each of the 1791 stories concerning youth, violence, or both was coded and analyzed for whether it included a public health perspective. RESULTS: There were five key findings. First, violence dominated local television news coverage. Second, the specifics of particular crimes dominated coverage of violence. Third, over half of the stories on youth involved violence, while more than two thirds of the violence stories concerned youth. Fourth, episodic coverage of violence was more than five times more frequent than thematic coverage, which included links to broader social factors. Finally, only one story had an explicit public health frame. CONCLUSIONS: Local television news provides extremely limited coverage of contributing etiological factors in stories on violence. If our nation's most popular source of news continues to report on violence primarily through crime stories isolated from their social context, the chance for widespread support for public health solutions to violence will be diminished.

    The resonance ionization laser ion source (RILIS) produces beams for the majority of experiments at the ISOLDE on-line isotope separator. A substantial improvement in RILIS performance has been achieved through a series of upgrade steps: replacement of the copper vapor lasers by a Nd:YAG laser; replacement of the old homemade dye lasers by new commercial dye lasers; installation of a complementary Ti:Sapphire laser system. The combined dye and Ti:Sapphire laser system with harmonics is capable of generating beams at any wavelength in the range of 210-950 nm. In total, isotopes of 31 different elements have been selectively laser-ionized and separated at ISOLDE, including recently developed beams of samarium, praseodymium, polonium, and astatine.

    Mass spectrometers typically output data in proprietary binary formats. While converter suites and standardized XML formats have been developed in response, these conversion steps come with non-negligible computational time and storage space overhead. As a result, simple, everyday data inspection tasks are often beyond the skills of the mass spectrometrist, who is unable to freely access the acquired data. We therefore here describe the unthermo library for convenient, platform-independent access to Thermo Scientific RAW files and the associated online playground to transform small and easily understandable scriptlets into executable programs for end-users. By fostering the provision of code examples and snippet exchange, the interested mass spectrometrist or researcher can use this playground to quickly assemble custom scripts for their particular purpose. In this way, the data in these RAW files can be mined much more readily and directly by the user, and fast, automated raw data extraction or analysis can finally become part of the daily routine of the mass spectrometrist.

    Biosensors based on luminescent bacteria may be valuable tools to monitor the chemical quality and safety of surface and drinking water. In this review, an overview is presented of the recombinant strains available that harbour the bacterial luciferase genes luxCDABE, and which may be used in an online biosensor for water quality monitoring. Many bacterial strains have been described for the detection of a broad range of toxicity parameters, including DNA damage, protein damage, membrane damage, oxidative stress, organic pollutants, and heavy metals. Most lux strains have sensitivities with detection limits ranging from milligrams per litre to micrograms per litre, usually with higher sensitivities in compound-specific strains. Although the sensitivity of lux strains can be enhanced by various molecular manipulations, most reported detection thresholds are still too high to detect levels of individual contaminants as they occur nowadays in European drinking waters. However, lux strains sensing specific toxic effects have the advantage of being able to respond to mixtures of contaminants inducing the same effect, and thus could be used as a sensor for the sum effect, including the effect of compounds that are as yet not identified by chemical analysis. An evaluation of the suitability of lux strains for monitoring surface and drinking water is therefore provided. PMID:21058029

    Most of medical journals now has it’s electronic version, available over public networks. Although there are parallel printed and electronic versions, and one other form need not to be simultaneously published. Electronic version of a journal can be published a few weeks before the printed form and must not has identical content. Electronic form of a journals may have an extension that does not contain a printed form, such as animation, 3D display, etc., or may have available fulltext, mostly in PDF or XML format, or just the contents or a summary. Access to a full text is usually not free and can be achieved only if the institution (library or host) enters into an agreement on access. Many medical journals, however, provide free access for some articles, or after a certain time (after 6 months or a year) to complete content. The search for such journals provide the network archive as High Wire Press, Free Medical Journals.com. It is necessary to allocate PubMed and PubMed Central, the first public digital archives unlimited collect journals of available medical literature, which operates in the system of the National Library of Medicine in Bethesda (USA). There are so called on- line medical journals published only in electronic form. It could be searched over on-line databases. In this paper authors shortly described about 30 data bases and short instructions how to make access and search the published papers in indexed medical journals. PMID:23322957

    Objective In 2004, after an 18-month investigation, the Food and Drug Administration (FDA) directed pharmaceutical manufacturers to add a black box warning to antidepressants regarding an increased risk of suicidality in children. It has been suggested that news media reporting played a critical role in the sharp declines in pediatric antidepressant use that occurred concurrent with this investigation. Our objective was to evaluate the quality, content and overall impression conveyed in news coverage of this issue. Methods We collected all news stories on pediatric antidepressant use and suicidality published in a convenience sample of 10 of the highest circulation print newspapers in the U.S., the three major television networks and a major cable news network in 2003 and 2004 (N=167). Two researchers coded news articles using a nine-item instrument. Item inter-rater reliability was .84 or greater. Results The quality of news reporting on key health messages included in FDA warnings was mixed. The overwhelming majority of news stories correctly described a risk of suicidality associated with pediatric antidepressant use as opposed to suicide itself. However, other key health messages highlighted in FDA warnings were often absent from news coverage. In terms of content, news stories, in particular television news, were more likely to include anecdotes of children harmed versus children helped by antidepressants while expert sources quoted were more likely to emphasize the benefits of antidepressants over their risks. However, the majority of news stories conveyed neither the overall impression that the risks of pediatric antidepressant use outweighed the benefits nor that the benefits outweighed the risks, and coverage became increasingly neutral over time. Conclusions Including key health messages in FDA safety warnings was not sufficient to ensure their communication to the public via the lay press, even though this information might have mitigated risks of pediatric antidepressant use.

    We have re-analysed the photon event files from the ROSAT all-sky survey. The main goal was to create a catalogue of point-like sources, which is referred to as the 2RXS source catalogue. We improved the reliability of detections by an advanced detection algorithm and a complete screening process. New data products were created to allow timing and spectral analysis. Photon event files with corrected astrometry and Moon rejection (RASS-3.1 processing) were made available in FITS format. The 2RXS catalogue will serve as the basic X-ray all-sky survey catalogue until eROSITA data become available. (2 data files).

    Printing ink vehicles that require no petroleum components were prepared by modifying vegetable oil. Physical properties of inks formulated with these vehicles meet or exceed the industry standards for lithographic and letterpress newsprint applications. Elimination of petroleum-based resin and reduced pigment requirements, due to the light vehicle color, provide a competitively priced alternative to petroleum-based inks of equal quality. These ink vehicles, made exclusively from soybean oil, were subjected to biodegradation, and the results were compared with those obtained with commercial vehicles. Results show that they degrade faster and more completely than commercial hybrid (partial) soy or mineral oil based vehicles. Fermentations were allowed to proceed for 5, 12, and 25 days. Both mono-and mixed cultures of microorganisms commonly found in soil were used. In 25 days, commercial mineral oil based vehicles degraded 17-27%, while commercial hybrid soy oil based vehicles degraded 58-68% and our 100% soy oil based vehicles degrade 82-92%. Similar studies were conducted with commercial news inks consisting of soy or mineral oil with petroleum resins along with the four colored pigments and USDA`s 100% soy oil based ink consisting of modified soybean oil and pigment. Results show that pigment slowed the degradation of ink vehicles; however, neither time nor type of pigment played a significant role. Also these inks were degraded by using {open_quotes}Modified Sturm Test{close_quotes} (Organization for Economic Cooperation and Development). In this method, test organisms were obtained from activated sludge, and the extent of degradation was determined by measuring carbon dioxide evolution. In all cases USDA`s ink degraded faster and more completely (for all four colors) than either hybrid soy oil based or petroleum based inks.

    Background: People are increasingly interested in health news. As a mass media, the ‘Islamic Republic of Iran Broadcasting’ (IRIB) has the highest number of target audiences. In Iran, some people follow health news via health programs on satellites and other means of communication. However, all of these programs do not live up to the standards of scientific evidence. In this study, we examined Tehran people’s trust in health news disseminated by the IRIB and other mass media outlets. Methods: A cross-sectional study was conducted in Tehran. Through multistage sampling, 510 households proportional to size were randomly selected from five regions of Tehran including northern, eastern, western, southern and central regions. One person from each household completed the questionnaire through interviews. The questionnaire included questions on people’s level of trust in health news delivered by the IRIB, satellite programs, the internet and magazines. It also included demographic questions. The validity and reliability of the questionnaire was evaluated. Results: Among the interviewees, 50.6% was female. The highest level of trust by the participants was observed in the IRIB (65.2%), and the lowest trust was observed in satellite news (43.4%); p< 0.001. The interviewees believed that the IRIB news broadcasters had more mastery over the subject than the ones in satellite channels (p< 0.001). The IRIB’s coverage of important and relevant health topics was also significantly perceived to be better than that of satellite news (p< 0.001). According to 83.5% of interviewees, the quality of health news had improved in the past 10 years. Fifty nine point eight percent of participants believed the quality and accuracy of the IRIB health news was monitored. Conclusion: People’s higher level of trust in domestic news as compared to foreign sources and the better status of domestic sources in other areas such as precision in reporting, coverage of more important news, its delivery in lay language, the news broadcasters’ proficiency, and other cases - from the participants’ point of view - can highlight the significance of designing interventions for changing health behavior among domestic health news producers. Therefore, the results of this study can prove useful to health news policy makers in the IRIB. PMID:25678993

    We have used the Australia Telescope Compact Array (ATCA) to search for faint radio sources in a ~3deg2 region of sky covered by the 2dF Galaxy Redshift Survey (2dFGRS, Cat. ). Over the region surveyed, the 1{sigma} noise level at 1.4GHz ranges from 20Jy to 1mJy. The survey region includes 365 2dFGRS galaxies, of which 316 have good-quality spectra (176 early-type galaxies or active galactic nuclei, and 140 star-forming galaxies). The fraction of 2dFGRS galaxies detected as radio sources in our survey rises from ~4% at a 3{sigma} detection limit of 0.3mJy to 12% at 75{mu}Jy, with roughly equal numbers of star-forming galaxies and active galactic nuclei (AGNs) being detected.

    A list of 216 target fields were observed with the Very Large Array (VLA). The instantaneous bandwidth was split into two parts, with one half centered at 5.0GHz (4.5-5.5GHz) and the other centered at 7.3GHz (6.8-7.8GHz); on 2012 October 26 and 2012 November 3. See section 2.1 During the first campaign with the Australia Telescope Compact Array (ATCA), from 2012 September 19-20, we observed 411 2FGL unassociated sources in a decl. range of [-90°, +10°] at 5.5 and 9GHz. The details of that observing campaign and results have been reported by Petrov et al. (2013, J/MNRAS/432/1294). We detected a total of 424 point sources. In a second ATCA campaign on 2013 September 25-28, we re-observed sources that were detected at 5GHz, but were not detected at 9GHz. See section 2.2. Follow-up observations of 149 targets selected from the VLA and ATCA survey above -30° decl. were conducted with the Very Long Baseline Array (VLBA) between 2013 Feb-Aug (VCS7 project; 4.128-4.608 and 7.392-7.872GHz simultaneously) and in 2013 Jun-Dec (campaign S5272; 7.392-7.872GHz only). See section 2.3. For sources with decl. below -30° we added 21 objects to the on-going LCS campaign (Petrov et al. 2011, J/MNRAS/414/2528) in 2013 Mar-2013 Jun at 8.200-8.520GHz. See section 2.4.

  1. AIDS and the news media.

    PubMed

    Nelkin, D

    1991-01-01

    News reports on AIDS have appeared at a time of general public concern about health risks, and, like the coverage of risk, the reporting on AIDS has been controversial. Perceptions of this disease have been linked to economic and personal stakes, professional ideologies, administrative responsibilities, and moral beliefs. It is from this perspective that news coverage of AIDS must be understood. The norms and practices of journalism, the technical uncertainties of risk evaluation, and the pressures placed on the media by various interests have influenced the reporting on this disease. However, media reports also shape the social context of the epidemic, affecting public perceptions, personal behavior, and policy agendas. PMID:1791792

  2. Online laser desorption-multiphoton postionization mass spectrometry of individual aerosol particles: molecular source indicators for particles emitted from different traffic-related and wood combustion sources.

    Direct inlet aerosol mass spectrometry plays an increasingly important role in applied and fundamental aerosol and nanoparticle research. Laser desorption/ionization (LDI) based techniques for single particle time-of-flight mass spectrometry (LDI-SP-TOFMS) are a promising approach in the chemical analysis of single aerosol particles, especially for the detection of inorganic species and distinction of particle classes. However, until now the detection of molecular organic compounds on a single particle basis has been difficult due to the high laser power densities which are required for the LDI process as well as due to the inherent matrix effects associated with this ionization technique. By the application of a two-step approach, where an IR desorption laser pulse is applied to perform a gentle desorption of organic material from the single particle surface and a second UV-laser performs the soft ionization of the desorbed species, this drawback of laser based single particles mass spectrometry can be overcome. The postionization of the desorbed molecules has been accomplished in this work by resonance enhanced multiphoton ionization (REMPI) using a KrF excimer laser (248 nm). REMPI allows an almost fragmentation free trace analysis of polycyclic aromatic hydrocarbons (PAHs) and their derivatives from individual single particles (laser desorption-REMPI postionization-single particle-time-of-flight mass spectrometry or LD-REMPI-SP-TOFMS). Crucial system parameters of the home-built aerosol mass spectrometer such as the power densities and the relative timing of both lasers were optimized with respect to the detectability of particle source specific organic signatures using well characterized standard particles. In a second step, the LD-REMPI-SP-TOFMS system was applied to analyze different real world aerosols (spruce wood combustion, gasoline car exhaust, beech wood combustion, and diesel car exhaust). It was possible to distinguish the particles from different sources by their molecular signature. Finally, exemplary ambient aerosol measurements have been carried out, which demonstrate the potential of the method for investigating urban aerosol and making contributions to source attribution studies.

    PubMed

    Previte, Josephine; Gurrieri, Lauren

    2015-01-01

    Through a textual and visual analysis of online news stories and public commentary about fat bodies, this article provides insights into the media's reporting on the "war on obesity." It identifies the stigmatizing role that the media plays. Specifically, the media draws on five key discourses in constructing fat bodies: pathologized, gazed upon, marginalized, controlled, and gendered. As news media coverage influences how society views health and policy issues, we argue that social marketers need to take an active role in changing the public's antifat attitudes through healthy lifestyle promotion tactics and strategies that reduce weight stigma.

Much information can be obtained from the national web site at http://www.eclipse.org.uk. Set up by the CLRC Rutherford Appleton Laboratory, on behalf of the UK Eclipse Group, the site is intended to keep viewers abreast of developments during the countdown to the eclipse. The list of contents includes: about eclipses; eclipse pictures; eclipse science; safety advice; latest news; and local information. There is also a wealth of images and video footage, so the site has been organized with the visitor having a small PC and modem in mind, so that the key information can be accessed as quickly as possible. Free colour leaflets containing useful details for eclipse watchers can be obtained from the Particle Physics and Astronomy Research Council. `The Sun - our local star' and `Neutrinos' are additions to PPARC's series introducing key areas of its science. They answer such questions as what the Sun is, what eclipses are, why the Sun is important and where neutrinos come from. They support the National Curriculum Key Stages 3 and 4 plus A-level physics. The A5 leaflets open out into an A2 sized double-sided wall chart and bulk quantitites are available for class sets, visitor centres, exhibitions, open days etc. A full list of PPARC materials can be found at the website http://www.pparc.ac.uk or by order from Mark Wells, PPARC, Polaris House, North Star Avenue, Swindon SN2 1SZ (fax: 01793 442002). A message has been received from George Care, Head of Physics in the Science Department at Mounts Bay School, Penzance, which we now pass on to our readers. During his application for electronic access to Physics Education via the Institute of Physics Affiliated Schools and Colleges scheme, George notes that his school is on the track of the eclipse this summer and he has invited us to pass on the details to anyone who would like to research the event. At the time of his correspondence, no-one had requested use of the school's facilities.

  12. Temporal and Cross Correlations in Business News

    NASA Astrophysics Data System (ADS)

    Mizuno, T.; Takei, K.; Ohnishi, T.; Watanabe, T.

    We empirically investigate temporal and cross correlations inthe frequency of news reports on companies, using a dataset of more than 100 million news articles reported in English by around 500 press agencies worldwide for the period 2003--2009. Our first finding is that the frequency of news reports on a company does not follow a Poisson process, but instead exhibits long memory with a positive autocorrelation for longer than one year. The second finding is that there exist significant correlations in the frequency of news across companies. Specifically, on a daily time scale or longer the frequency of news is governed by external dynamics, while on a time scale of minutes it is governed by internal dynamics. These two findings indicate that the frequency of news reports on companies has statistical properties similar to trading volume or price volatility in stock markets, suggesting that the flow of information through company news plays an important role in price dynamics in stock markets.

    2012-09-01

    These catalogs, prepared using the SExtractor package (Bertin & Arnouts 1996A&AS..117..393B), are based on the version v2.0 of the reduced, calibrated, stacked and mosaiced images acquired with HST and ACS as part of the GOODS ACS Treasury program and of the PANS program of search for Type Ia supernovae at high redshift. It supersedes the "Initial Results" version (Giavalisco et al. 2004ApJ...600L..93G, Cat. II/261) The catalogs are z-band based, that is, source detection has been made using the z-band images. A variety of photometric apertures defined during the detection process have then been used as "fixed apertures" in the i, v and b-band images to derive the multi-band photometry. The r2.0z catalog release is based on the v2.0 images, which have significantly longer total exposure times in the z850 bandpass, and somewhat longer exposure times in the i775 and V606 bands as well. The only significant difference in the catalogs, other than that of being based on deeper data, is that a small astrometric offset was applied to the declination of GOODS-North images (only), from a comparison with SDSS, 2MASS and VLA (Morrison et al. 2010, Cat. J/ApJS/188/178): Dec(v2.0)=Dec(v1.0)-0.320arcsec (8 data files).

    We obtained two sets of A-array observations with the Karl G. Jansky Very Large Array (VLA). The first set of observations of the stellar cluster at the Galactic center were obtained on 2011 July 8-9 and 2011 August 31-September 1 at 44GHz (program 11A-224). Further details of these first-epoch observations are given in Yusef-Zadeh et al. (2014ApJ...792L...1Y). We reobserved the region within 30" of Sgr A* on 2014 February 21, again using the VLA in its A-configuration at 44GHz. We also carried out A-array observations (program 14A-232) in the Ka (9mm) band on 2014 March 9 at 34.5GHz. We searched for NIR counterparts to compact radio sources using high-angular resolution AOs assisted imaging observations acquired with the VLT/NACO (NAos-COnica). A Ks-band (central wavelength 2.18um) image was obtained in a rectangular dither pattern on 2012 September 12. L'-band (3.8um) observations were obtained during various observing runs between 2012 June and September. (1 data file).

    Along with the increase in the number of young people applying to enter higher education announced back in July, the UK Department for Education and Employment noted that over a thousand more graduates had applied for postgraduate teacher training when compared with the same time in 1998. It appeared that the `Golden hello' programme for new mathematics and science teachers had succeeded in its aim of encouraging applicants in those subjects: an increase of 37% had been witnessed for maths teaching, 33% for physics and 27% for chemistry. Primary teacher training was also well on target with over five applicants seeking each available place. Statistics for UK schools released in August by the DfEE show that 62% of primary schools and 93% of secondary schools are now linked to the Internet (the corresponding figures were 17% and 83% in 1998). On average there is now one computer for every 13 pupils at primary school and one for every eight students in secondary school. The figures show continuing progress towards the Government's target of ensuring that all schools, colleges, universities, libraries and as many community centres as possible should be online (with access to the National Grid for Learning) by 2002.

    Emission inventory of air pollutants is the key to understand the spatial and temporal distribution of atmospheric pollutants and to accurately simulate the ambient air quality. The currently established emission inventories are still limited on spatial and temporal resolution which greatly influences the numerical prediction accuracy of air quality. With coal-fired stationary sources considered, this study analyzed the total emissions and monthly variation of main pollutants from them in 2012 as the basic year, by collecting the on-line monitoring data for power plants and atmospheric verifiable accounting tables of Jiangsu Province. Emission factors in documents are summarized and adopted. Results indicated that the emission amounts of SO2, NOx, TSP, PM10, PM2.5, CO, EC, OC, NMVOC and NH3 were 106.0, 278.3, 40.9, 32.7, 21.7, 582.0, 3.6, 2.5, 17.3 and 2.2 kt, respectively. They presented monthly variation with high emission amounts in February, March, July, August and December and low emissions in September and October. The reason may be that more coal are consumed which leads to the increase of pollutants emitted, to satisfy the needs, of heat and electricity power supply in cold and hot periods. Local emission factors are needed for emission inventory studies and the monthly variation should be considered when emission inventories are used in air quality simulation. PMID:26592003

    2008-01-01

    Assessing the potential property and social impacts of an event, such as tornado or wildfire, continues to be a challenging research area. From financial markets to disaster management to epidemiology, the importance of understanding the impacts that events create cannot be understated. Our work describes an approach to fuse information from multiple sources, then to analyze the information cycles to identify prior temporal patterns related to the impact of an event. This approach is then applied to the analysis of news reports from multiple news sources pertaining to several different natural disasters. Results show that our approach can project the severity of the impacts of certain natural disasters, such as heat waves on droughts and wild fires. In addition, results show that specific types of disaster consistently produce similar impacts when each time they occur.

    A new open-access online database, E-SovTox, is presented. E-SovTox provides toxicological data for substances relevant to the EU Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) system, from publicly-available Russian language data sources. The database contains information selected mainly from scientific journals published during the Soviet Union era. The main information source for this database - the journal, Gigiena Truda i Professional'nye Zabolevania [Industrial Hygiene and Occupational Diseases], published between 1957 and 1992 - features acute, but also chronic, toxicity data for numerous industrial chemicals, e.g. for rats, mice, guinea-pigs and rabbits. The main goal of the abovementioned toxicity studies was to derive the maximum allowable concentration limits for industrial chemicals in the occupational health settings of the former Soviet Union. Thus, articles featured in the database include mostly data on LD50 values, skin and eye irritation, skin sensitisation and cumulative properties. Currently, the E-SovTox database contains toxicity data selected from more than 500 papers covering more than 600 chemicals. The user is provided with the main toxicity information, as well as abstracts of these papers in Russian and in English (given as provided in the original publication). The search engine allows cross-searching of the database by the name or CAS number of the compound, and the author of the paper. The E-SovTox database can be used as a decision-support tool by researchers and regulators for the hazard assessment of chemical substances. PMID:20822322

    2015-06-01

    Exposure to news, opinion, and civic information increasingly occurs through social media. How do these online networks influence exposure to perspectives that cut across ideological lines? Using deidentified data, we examined how 10.1 million U.S. Facebook users interact with socially shared news. We directly measured ideological homophily in friend networks and examined the extent to which heterogeneous friends could potentially expose individuals to cross-cutting content. We then quantified the extent to which individuals encounter comparatively more or less diverse content while interacting via Facebook's algorithmically ranked News Feed and further studied users' choices to click through to ideologically discordant content. Compared with algorithmic ranking, individuals' choices played a stronger role in limiting exposure to cross-cutting content. PMID:25953820

    2013-01-01

    The infection times of individuals in online information spread such as the inter-arrival time of Twitter messages or the propagation time of news stories on a social media site can be explained through a convolution of lognormally distributed observation and reaction times of the individual participants. Experimental measurements support the lognormal shape of the individual contributing processes, and have resemblance to previously reported lognormal distributions of human behavior and contagious processes.

    Half-hourly mass concentrations water-soluble ions (WSIs) and PM2.5 were measured online a Rapid Collector of Fine Particles and Ion Chromatography system (RCFP-IC) and FH62C14 Continuous Particulate Monitor in Nanjing from October 18, 2013 to November 17, 2014. The WSIs concentration ranged from 7.07 to 333.42 μg m(-3) with an annual mean of 76.32 μg m(-3). The WSIs ranked in the order of SO4(2-) > NH4(+) > NO3(-) > Cl(-) > NO2(-) > K(+) > Ca(2+) > Na(+) > Mg(2+). The PM2.5 concentration ranged from 4.00 to 400 μg m(-3) with an annual mean of 83.58 μg m(-3). The concentrations of WSIs varied in the order of winter (115.77 μg m(-3)) > spring (76.10 μg m(-3)) > autumn (63.72 μg m(-3)) > summer (59.75 μg m(-3)), with the highest level in January (123.99 μg m(-3)) and lowest level in August (43.73 μg m(-3)). Different WSIs had distinct diurnal variations. The source analysis of the WSIs in the PCA/APCS mode illustrated that the sources consisted of secondary aerosol, coal combustion, mineral dust, biomass burning, traffic emissions and sea salt. In addition, there were seasonal variations amongst the various sources. The haze formation mechanism was different in summer and winter. The winter was dominated by NH4NO3 (18.56%), (NH4)2SO4 (28.63%), NH4(+) (11.27%), SO4(2-) (18.35%) and NO3(-) (13.13%), and by NH3 (25.93%), (NH4)2SO4 (13.37%), SO4(2-) (15.74%) and NO3(-) (9.97%) in summer. Consequently, the proportions of HCl, HNO3, NH4(+), SO4(2-) and NO3(-) were much larger during haze episodes in winter, while it was dominated by NH4NO3, NH4(+), (NH4)2SO4, SO4(2-) and NO3(-) during summer haze episodes.

  13. Biofantasies: genetics and medicine in the print news media.

    PubMed

    Petersen, A

    2001-04-01

    The contemporary news media is an important site for exploring the diverse and complex cultural images of genetics and its medical possibilities, and of the mechanisms by which these images are (re) produced and sustained. This article investigates how the print news media 'frames' stories on genetics and medicine. It is based on a discourse analysis of articles appearing in three Australian newspapers in the late 1990s. Gene stories were found to be prominent in each of the newspapers, and to emphasise the medical benefits of genetic research. Stories frequently cite and quote scientists, who explain the nature and significance of the research and/or its implications for treatment or prevention. Many stories focus on new genetic discoveries, and portray genetic researchers as involved in a quest to unlock nature's secrets. Stories of hope, and depictions of geneticists as warriors or heroes, appear regularly. The positive vision of genetics is supported by the use of particular metaphors, accompanying illustrative material, 'human interest' stories, and reference to credible sources. There is rarely mention of the influence of non-genetic factors and 'multifactorial' interactions on disorders, or questioning of the goals, direction, methods, or value of genetic research. Scientists made extensive use of the media in their efforts to maintain a positive image of research in the face of public concerns about scientists 'going too far', following the announcement of the cloning of Dolly. Boundaries were drawn between 'therapeutic cloning'--implicitly defined as 'good', useful, and legitimate--and 'reproductive cloning'--seen as 'bad', dangerous, and illegitimate. By framing news stories as they do, the print news media are likely to exert a powerful influence on public responses to health problems. With new genetic technologies becoming more integrated in preventive medicine and public health, it is important to investigate how news stories help shape the agenda for public debate.

    2012-06-01

    Research into the reliability of news reports on 'global warming' published by the UOL media group, Folha.com and Folha de S. Paulo reveals a tendency for positions to be polarized between complete agreement with the assertion that the causes are entirely anthropogenic (the dominant position) and complete denial. The sample comprised 676 news items from more than 3,000 published on the topic between October 2007 and October 2008. The study tested the hypothesis that the news output of the three media outlets is dominated by the positions of the Intergovernmental Panel on Climate Change. In absolute terms, the panel is the most frequently cited source, since just seven news items comprised exceptions to the 'consensus.' These contrary opinions made up 1.03% of the sample.

    We study complementary navigation of news and blog, where Wikipedia entries are utilized as fundamental knowledge source for linking news articles and blog feeds/posts. In the proposed framework, given a topic as the title of a Wikipedia entry, its Wikipedia entry body text is analyzed as fundamental knowledge source for the given topic, and terms strongly related to the given topic are extracted. Those terms are then used for ranking news articles and blog posts. In the scenario of complementary navigation from a news article to closely related blog posts, Japanese Wikipedia entries are ranked according to the number of strongly related terms shared by the given news article and each Wikipedia entry. Then, top ranked 10 entries are regarded as indices for further retrieving closely related blog posts. The retrieved blog posts are finally ranked all together. The retrieved blog posts are then shown to users as blogs of personal opinions and experiences that are closely related to the given news article. In our preliminary evaluation, through an interface for manually selecting relevant Wikipedia entries, the rate of successfully retrieving relevant blog posts improved.

  20. The Interaction of Production and Consumption in the News Media Social Space

    Graham, Gary; Kerrigan, Finola; Mehmood, Rashid; Rahman, Mustafizur

    Newspapers are operating in increasingly competitive and fragmented markets for audiences and advertising revenues, government media policy and changing audience requirements for news and the ways in which it is presented and delivered. A growing army of bloggers and amateur citizen journalists now delivers - but rarely edits - content for all media platforms, while new media technologies, combined with the changing structure of global news industries, are radically changing the ways in which newspapers and media business functions and struggles for profitability. Our research sought to answer the question of how the internet is impacting on producer/consumer value activities in the news media supply chain. To answer this question initial descriptive statistical analysis was performed on 51 newspapers. This was followed by a focus group undertaken with London-based news media organizations and bloggers. The findings showed that in spite of initial fear and rejection, the internet is now firmly embedded in news media supply chain operations. Firms are now using the internet as an operant resource and working proactively with consumers to develop various forms of relationship value. We highlight the role of consumers in the creation of news (editorial) content and consumer-driven moves toward a merged media platform of distribution (including television, online, mobile and printed forms). Regional news media organizations will probably continue to survive if they are able to supply a highly specialized and 'hyper local' community service. This will be in the form of 'hybrid' content: analysis, interpretation and investigative reporting in a print product that appears less than daily combined with constant updating and reader interaction on the web.

    Introduction Few studies have explored sources of e-cigarette awareness and peoples' e-cigarette information needs, interests, or behaviors. This study contributes to both domains of e-cigarette research. Methods Results are based on a 2014 e-cigarette focused survey of 519 current smokers from a nationally representative research panel. Results Smokers most frequently reported seeing e-cigarettes in stores (86.4%) and used in person (83%). Many (73%) had also heard about e-cigarettes from known users, broadcast media ads (68%), other (print, online) advertisements (71.5%), and/or from the news (60.9%); sources of awareness varied by e-cigarette experience. Most smokers (59.9%) believed e-cigarettes are less harmful than regular cigarettes, a belief attributed to “common sense” (76.4%), the news (39.2%), and advertisements (37.2%). However, 79.5% felt e-cigarette safety information was important. Over one-third said they would turn to a doctor first for e-cigarette safety information, although almost a quarter said they would turn to the Internet or product packaging first. Most (59.6%) ranked doctors as the most trustworthy risk source, and 6.8% had asked a health professional about e-cigarettes. Conclusions Future research should explore the content of e-cigarette information sources, their potential impact, and ways they might be strengthened or changed through regulatory and/or educational efforts.

  4. Design Scenarios for Web-Based Management of Online Information

    NASA Astrophysics Data System (ADS)

    Hepting, Daryl H.; Maciag, Timothy

    The Internet enables access to more information, from a greater variety of perspectives and with greater immediacy, than ever before. A person may be interested in information to become more informed or to coordinate his or her local activities and place them into a larger, more global context. The challenge, as has been noted by many, is to sift through all the information to find what is relevant without becoming overwhelmed. Furthermore, the selected information must be put into an actionable form. The diversity of the Web has important consequences for the variety of ideas that are now available. While people once relied on newspaper editors to shape their view of the world, today's technology creates room for a more democratic approach. Today it is easy to pull news feeds from a variety of sources and aggregate them. It is less easy to push that information to a variety of channels. At a higher level, we might have the goal of collecting all the available information about a certain topic, on a daily basis. There are many new technologies available under the umbrella of Web 2.0, but it can be difficult to use them together for the management of online information. Web-based support for online communication management is the most appropriate choice to address the deficiencies apparent with current technologies. We consider the requirements and potential designs for such information management support, by following an example related to local food.

  5. When Pictures Waste a Thousand Words: Analysis of the 2009 H1N1 Pandemic on Television News

    Objectives Effective communication by public health agencies during a pandemic promotes the adoption of recommended health behaviours. However, more information is not always the solution. Rather, attention must be paid to how information is communicated. Our study examines the television news, which combines video and audio content. We analyse (1) the content of television news about the H1N1 pandemic and vaccination campaign in Alberta, Canada; (2) the extent to which television news content conveyed key public health agency messages; (3) the extent of discrepancies in audio versus visual content. Methods We searched for “swine flu” and “H1N1” in local English news broadcasts from the CTV online video archive. We coded the audio and visual content of 47 news clips during the peak period of coverage from April to November 2009 and identified discrepancies between audio and visual content. Results The dominant themes on CTV news were the vaccination rollout, vaccine shortages, long line-ups (queues) at vaccination clinics and defensive responses by public health officials. There were discrepancies in the priority groups identified by the provincial health agency (Alberta Health and Wellness) and television news coverage as well as discrepancies between audio and visual content of news clips. Public health officials were presented in official settings rather than as public health practitioners. Conclusion The news footage did not match the main public health messages about risk levels and priority groups. Public health agencies lost control of their message as the media focused on failures in the rollout of the vaccination campaign. Spokespeople can enhance their local credibility by emphasizing their role as public health practitioners. Public health agencies need to learn from the H1N1 pandemic so that future television communications do not add to public confusion, demonstrate bureaucratic ineffectiveness and contribute to low vaccination rates.

  6. NEWS: AAPT Summer Meeting

    2000-11-01

    The 2000 Summer Meeting of the American Association of Physics Teachers (AAPT) was held from 28~July-2~August at the University of Guelph in Ontario, Canada. Despite somewhat rainy weather throughout the week, the annual gathering was an enjoyable one, filled with interesting talks on the state of physics education in North America. Using a new scheduling format for the summer meeting, all of the paid workshops and tutorials were held on Saturday and Sunday 29-30 July. The invited and contributed papers for the main AAPT meeting were then presented on Monday, Tuesday and Wednesday. As had been done in 1999 in San Antonio, a two-day tandem meeting dedicated to Physics Education Research (PER) was held on Wednesday and Thursday 2-3 August, immediately after the main AAPT meeting. Over the three days of the main meeting, 60 sessions were held under the sponsorship of various AAPT committees. These included sessions (numbers in parentheses) organized by the committees on Apparatus (1), Astronomy Education (3), Awards (2), Computers (5), Graduate Education (2), High Schools (1), History and Philosophy (1), Instructional Media (3), International Education (1), Laboratories (2), Pre-High School Education (2), Programs (4), Professional Concerns (6), Research in Physics Education (8), Science Education for the Public (2), Two-Year Colleges (5), Undergraduate Education (7) and Women in Physics (4). Figure 1. Guelph Church of Our Lady. The main meeting opened on Sunday evening with an invited lecture by Dr John J Simpson from the host institution, the University of Guelph, describing the Sudbury Neutrino Observatory. At the ceremonial session that began the activities on Monday morning, recognition was given to Clifford Swartz for his almost 30 years of service as Editor of the AAPT journal, The Physics Teacher. This was followed by an invited talk by Jim Nelson from Seminole County Public School in Florida, who received the Excellence in Pre-College Teaching Award. The session concluded with the talk by this year's award winner for Excellence in Introductory College teaching, Dr Dwight Neuenschwander from Southern Nazarene University in Oklahoma. Dwight's talk, invoking both Charles Dickens' A Christmas Carol and Robert Pirsig's Zen and the Art of Motorcycle Maintenance, was memorable for clarifying both the connections and the differences between physics and physics teaching. At a second ceremonial session on Tuesday, Terrence Walker of The Ohio State University gave the Klopsteg Memorial Lecture, entitled The Big Bang: Seeing Back to the Beginning. This was followed by the presentation of the Robert A Millikan Award Lecture - Beauty in Physics and the Arts, by Thomas Rossing of Northern Illinois University. Over the years Tom has made many contributions to the teaching of the physics of sound and music, and his lecture made wonderful connections between physics and the arts. At the first plenary session on Monday, Dr Elaine Seymour, a sociologist from the University of Colorado, gave a talk entitled: We Know Science Majors Are Lost Because of Poor Teaching, But Why Do They Resist Our Efforts To Improve Their Learning Experience? She described students' responses and resistance to the implementation of active-learning methods. The talk was thought-provoking, particularly when so many other talks at this meeting described new attempts to incorporate such methods in different educational settings. At the second plenary session on Wednesday, Eric Poisson from the University of Guelph gave a very interesting talk about Gravitational Wave Astronomy and the LIGO and VIRGO projects, including their theoretical motivation and expected experimental results. On Tuesday evening there was a very special show of physics demonstrations by the `Third Eye' group from China. Their presentations embody a very interesting philosophy. Each demonstration is designed to illustrate one or more basic concepts in physics in a way that will be both memorable and thought-provoking. Often these presentations have evolved, and at each stage their goal is to be able to accomplish the same demonstration with ever-simpler equipment. Given that we all live under financial constraints, the `third eye' refers to the ability to look around and find a useful piece of a demonstration apparatus amongst what others might perceive to be junk. All in all, it was a very stimulating and interesting presentation, and one can easily see why this group tours China to the rave reviews of the students there. As is true every year, the wealth of interesting and valuable work shared in the parallel sessions of contributed papers was astounding. As always, I found myself running from building to building in an attempt to hear as many talks as I could possibly attend. Often a colleague and I would split up to hear different talks, and then share what we'd learned over a meal later in the day. What follows are a few highlights of what we heard and saw in some of those sessions. As one would expect given the trend of recent years, there were many interesting talks about the incorporation of computers and instructional media in introductory physics teaching. Paris Naik from the University of Illinois presented a paper on their web-based Interactive Examples. These are very well thought-out homework problems that provide interactive help in the spirit of a Socratic dialogue. They can be viewed at webug.physics.uiuc.edu/courses/ie.html. Mario Belloni and Wolfgang Christian, both from Davidson College, each gave a talk on the use of Physlets, scriptable Java-based interactive physics problems. These can be sampled at webphysics.davidson.edu/physletprob. Ruth Chabay from Carnegie Mellon University presented the Visual Python real-time, three-dimensional graphics environment in which their first-year students are programming their own visualization of physical phenomena. Its power, ease of use and freeware usage make it a must-see at cil.andrew.cmu.edu/projects/visual. David Sokoloff (University of Oregon) and Priscilla Laws (Dickinson College) led a discussion session on the Interactive Lecture Demonstrations that they have been developing to promote active learning in the classroom. Loren Winters of the North Carolina School of Science and Mathematics showed some very fine work done with digital video cameras, both in producing motion videos for frame-by-frame analysis and in producing still images of high-speed phenomena. Finally, Patrick Tam of Humboldt State University in California talked about the Multimedia Resource for Learning and Online Teaching (MERLOT), a project to organize and review the proliferation of internet-based teaching materials that are rapidly becoming available. Their purpose is to make it easier for teachers like us to sift through the plethora of new innovations, to locate those that are potentially useful in our teaching, and finally to implement them effectively. You can check out the project on the web at www.merlot.org. As is evident from the number of sessions of contributed papers and the tandem conference, the quality and quantity of physics education research into new curricula and teaching methods continue to increase. A number of interesting areas were discussed including interactive lecture techniques, studio-classroom approaches combining lectures and labs, assessment techniques, and identifying and correcting student misconceptions. In addition to the plenary talks on current research topics in physics mentioned above, there were sessions on Space Physics and Hot Topics in Physics. There were sessions on professional and career concerns including Preparing Future Physics Faculty, New Faculty Experiences and Concerns, Balancing Career and Family, How Physics Topics Support the Job Market and Recruiting and Retaining Women in Physics. Whether one was a high school teacher or a university professor, this was an enjoyable and educational meeting. We all look forward to the Winter 2001 meeting from 6-11 January in San Diego, and to next summer's meeting from 21-25 July in Rochester, New York.

    Recent mass shootings by persons seemingly afflicted with serious mental illness (SMI) have received extensive news media coverage and prompted national dialogue about the causes of, and policy responses to, mass shootings. News media framing of SMI as a cause of gun violence may influence public attitudes about persons with SMI and support for gun violence prevention proposals. We analyzed the content of a 25% random sample of news stories on SMI and gun violence published in 14 national and regional news sources from 1997 to 2012. Across the study period, most news coverage occurred in the wake of mass shootings, and "dangerous people" with SMI were more likely than "dangerous weapons" to be mentioned as a cause of gun violence.

    Swain, Kristen Alley

    2015-01-01

    This study examined the role of crisis advice appearing in US news coverage of the 2001 anthrax attacks. Coverage of any crisis can spark public outrage, including fear, speculation, and contradictory or confusing evidence, especially when the stories do not contain practical advice. Five coders analyzed 833 news stories from 272 major US newspapers, the Associated Press, National Public Radio, and 4 major US television networks. Practical advice appeared in only a quarter of the stories, even though practical advice for self-protection was mentioned 3 times more often than the vague advice that simply advised people not to panic. Public health officials provided the most practical advice, while scientists provided the least practical advice. Stories containing practical advice also provided more elucidating information, explaining why the threat was low, reducible, treatable, and detectable. Over the 3 phases of the anthrax crisis, an inverse relationship appeared between the amount of news coverage containing practical advice compared to "outrage rhetoric." Stories mentioned practical advice more often during the post-impact phase than earlier in the crisis. Elucidating, explanatory advice emphasized actions, risk comparisons, and tradeoffs. The findings indicate that when journalists use credible sources to provide practical advice and avoid speculation, their coverage can prevent the spread of misinformation and confusion during a bioterror attack. Also, journalists should provide context and sourcing when discussing advice during the outbreak and impact phases of the crisis, because these explanations could counteract outrage and threat distortion.

  13. Source Water Management for Disinfection By-Product Control using New York City's Operations Support Tool and On-Line Monitoring

    NASA Astrophysics Data System (ADS)

    Weiss, W. J.; Becker, W.; Schindler, S.

    2012-12-01

    The United States Environmental Protection Agency's 2006 Stage 2 Disinfectant / Disinfection Byproduct Rule (DBPR) for finished drinking waters is intended to reduce overall DBP levels by limiting the levels of total trihalomethanes (TTHM) and five of the haloacetic acids (HAA5). Under Stage 2, maximum contaminant levels (MCLs), 80 μg/L for TTHM and 60 μg/L for HAA5, are based on a locational running annual average for individual sites instead of as the system-wide quarterly running annual average of the Stage 1 DBPR. This means compliance will have to be met at sampling locations of peak TTHM and HAA5 concentrations rather than an average across the entire system. Compliance monitoring under the Stage 2 DBPR began on April 1, 2012. The New York City (NYC) Department of Environmental Protection (DEP) began evaluating potential impacts of the Stage 2 DBPR on NYC's unfiltered water supply in 2002 by monitoring TTHM and HAA5 levels at various locations throughout the distribution system. Initial monitoring indicated that HAA5 levels could be of concern in the future, with the potential to intermittently violate the Stage 2 DBPR at specific locations, particularly those with high water age. Because of the uncertainty regarding the long-term prospect for compliance, DEP evaluated alternatives to ensure compliance, including operational changes (reducing chlorine dose, changing flow configurations to minimize water age, altering pH, altering source water withdrawals); changing the residual disinfectant from free chlorine to chloramines; and engineered treatment alternatives. This paper will discuss the potential for using DEP's Operations Support Tool (OST) and enhanced reservoir monitoring to support optimization of source water withdrawals to minimize finished water DBP levels. The OST is a state-of-the-art decision support system (DSS) to provide computational and predictive support for water supply operations and planning. It incorporates a water supply system simulation model (OASIS, HydroLogics, Inc.), reservoir water quality models, a near real-time monitoring network, and hydrologic forecasts to provide analytical support for both long-term planning and near-term operations. The OST helps managers and operators balance multiple objectives, including water supply reliability, water quality, and environmental and community release objectives. This paper will describe the results of initial testing to evaluate the potential to reduce DBP levels by managing source water withdrawals to minimize the transport of natural organic matter (NOM) precursors from upper reservoirs. Operating rules were developed that take advantage of selective withdrawal capabilities at some upstate reservoirs and the inherent flexibility of the overall water supply system, seeking to minimize DBPs within the larger framework of water supply, water quality, environmental, and regulatory objectives. The results demonstrated that there is substantial flexibility within the system to manage DBP levels, in some cases providing the potential for reductions of DBP precursors of nearly 10%. Additional research is underway that seeks to better understand the sources of natural organic matter in the NYC watershed to provide guidance for on-line monitoring to be used with the OST to support real-time operation support for DBP control.

    Classroom Activities Mean Teamwork As much as any other facet of the editing and production of the Journal, the Classroom Activity series means teamwork! The aim is for activities to be interesting and accessible to introductory students, based on inexpensive and readily available materials, connected by content to some part of the Journal issue, able to be integrated into the high school curriculum, and safe. There need to be questions posed and answers at the ready. Additional information in print and on the Web needs to be identified and checked. The activities are designed to be ready for teachers to hand to students, so they really need to work-that means that they go through a lot of testing in Journal House where there is, quite fittingly, no lab. This is a tall order, one requiring someone with experience in high school teaching. From the start of the Activities in September 1997, Nancy Gettys has had a major role in their success. While Nancy's primary responsibility is as the Technical Editor of JCE Software, she has experience in teaching high school and has called on that experience to try and test, expand, try again, plan the illustrations (remember the photographs of the activities with surface phenomena that were featured in the table of contents of the February 1998 issue?), and perhaps hardest of all-tell us when something will just not work in high school. Nancy continues to work with the Classroom Activities, but she now has a colleague in fellow high school teacher Erica Jacobsen who has recently joined our staff. Introducing... Erica Jacobsen joined our staff last fall as an editorial assistant and has recently become an assistant editor. She received her undergraduate degree in education from the University of Wisconsin-Madison. Her teaching licenses include certifications in chemistry, physics, biology, and natural science for grades six through twelve. During her undergraduate years, she worked with the Chemical Education Group. Her undergraduate research and senior thesis were directed by John W. Moore and centered on the subject of HIV and its use as a topic in the chemistry curriculum. The research culminated in writing and publishing "HIV-1 Protease: An Enzyme at Work," a videotape and teacher/student guide offered by the Journal of Chemical Education Software. After graduation, Erica taught chemistry, AP chemistry, and physics for two years at a rural public high school in Minnesota. During her teaching, as a reader of the Journal, she was delighted to see the introduction of the Classroom Activities feature. She found the ready-made activities a great complement to her "hands-on, minds-on" curriculum. Due to her husband's job transfer, she has returned to Madison and is even more delighted to now be a part of the development of Classroom Activities. Her duties at Journal House include helping to test, research, and write Classroom Activities. She divides her time between working at Journal House, taking additional science coursework at the university for professional development, and tutoring chemistry students. She is settling in to her new life in Madison and she and her husband enjoy exploring the Wisconsin outdoors together.

    Millions of people worldwide use the Internet daily as a source of health information. Google is the most popular search engine and is used by patients and physicians to search for online health-related information. This study aimed to evaluate changes in web search behavior occurring in English-speaking countries over time for terms related to epilepsy and epileptic seizures. Using Google Trends, data on global search queries for the terms "epilepsy", "seizure", and "seizures" between January 2004 and September 2013 were analyzed. The reduction over time in search queries for the term "epilepsy" (and, to a lesser extent, "seizures") was counterbalanced by an increased trend in searches for the term "seizure". Most terms associated with the search queries were related to symptoms of seizures, especially tonic-clonic seizures, and to seizures occurring in children. Three peaks in search volume over the period studied corresponded to news of celebrities having seizures. The volume of searches for the term "epilepsy SUDEP" was found to be enormously increased over time. Most people appear to use search engines to look for terms related to epilepsy to obtain information on seizure symptoms, possibly to aid initial self-diagnosis. Fears and worries about epileptic seizures and news on celebrities with epilepsy seem to be major factors that influence online search behavior. PMID:24361764

  18. Improving Naive Bayes with Online Feature Selection for Quick Adaptation to Evolving Feature Usefulness

    SciTech Connect

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-19

    The definition of what makes an article interesting varies from user to user and continually evolves even for a single user. As a result, for news recommendation systems, useless document features can not be determined a priori and all features are usually considered for interestingness classification. Consequently, the presence of currently useless features degrades classification performance [1], particularly over the initial set of news articles being classified. The initial set of document is critical for a user when considering which particular news recommendation system to adopt. To address these problems, we introduce an improved version of the naive Bayes classifier with online feature selection. We use correlation to determine the utility of each feature and take advantage of the conditional independence assumption used by naive Bayes for online feature selection and classification. The augmented naive Bayes classifier performs 28% better than the traditional naive Bayes classifier in recommending news articles from the Yahoo! RSS feeds.

  19. The association between exaggeration in health related science news and academic press releases: retrospective observational study

    Objective To identify the source (press releases or news) of distortions, exaggerations, or changes to the main conclusions drawn from research that could potentially influence a reader’s health related behaviour. Design Retrospective quantitative content analysis. Setting Journal articles, press releases, and related news, with accompanying simulations. Sample Press releases (n=462) on biomedical and health related science issued by 20 leading UK universities in 2011, alongside their associated peer reviewed research papers and news stories (n=668). Main outcome measures Advice to readers to change behaviour, causal statements drawn from correlational research, and inference to humans from animal research that went beyond those in the associated peer reviewed papers. Results 40% (95% confidence interval 33% to 46%) of the press releases contained exaggerated advice, 33% (26% to 40%) contained exaggerated causal claims, and 36% (28% to 46%) contained exaggerated inference to humans from animal research. When press releases contained such exaggeration, 58% (95% confidence interval 48% to 68%), 81% (70% to 93%), and 86% (77% to 95%) of news stories, respectively, contained similar exaggeration, compared with exaggeration rates of 17% (10% to 24%), 18% (9% to 27%), and 10% (0% to 19%) in news when the press releases were not exaggerated. Odds ratios for each category of analysis were 6.5 (95% confidence interval 3.5 to 12), 20 (7.6 to 51), and 56 (15 to 211). At the same time, there was little evidence that exaggeration in press releases increased the uptake of news. Conclusions Exaggeration in news is strongly associated with exaggeration in press releases. Improving the accuracy of academic press releases could represent a key opportunity for reducing misleading health related news. PMID:25498121

  20. Space Shuttle Status News Conference

    2005-01-01

    Richard Gilbech, External Tank "Tiger Team" Lead, begins this space shuttle news conference with detailing the two major objectives of the team. The objectives include: 1) Finding the root cause of the foam loss on STS-114; and 2) Near and long term improvements for the external tank. Wayne Hale, Space Shuttle Program Manager, presents a chart to explain the external tank foam loss during STS-114. He gives a possible launch date for STS-121 after there has been a repair to the foam on the External Tank. He further discusses the changes that need to be made to the surrounding areas of the plant in New Orleans, due to Hurricane Katrina. Bill Gerstemaier, NASA Associate Administrator for Space Operations, elaborates on the testing of the external tank foam loss. The discussion ends with questions from the news media about a fix for the foam, replacement of the tiles, foam loss avoidance, the root cause of foam loss and a possible date for a new external tank to be shipped to NASA Kennedy Space Center.

  1. The NEWS Water Cycle Climatology

    2012-01-01

    NASA's Energy and Water Cycle Study (NEWS) program fosters collaborative research towards improved quantification and prediction of water and energy cycle consequences of climate change. In order to measure change, it is first necessary to describe current conditions. The goal of the first phase of the NEWS Water and Energy Cycle Climatology project was to develop "state of the global water cycle" and "state of the global energy cycle" assessments based on data from modern ground and space based observing systems and data integrating models. The project was a multi-institutional collaboration with more than 20 active contributors. This presentation will describe the results of the water cycle component of the first phase of the project, which include seasonal (monthly) climatologies of water fluxes over land, ocean, and atmosphere at continental and ocean basin scales. The requirement of closure of the water budget (i.e., mass conservation) at various scales was exploited to constrain the flux estimates via an optimization approach that will also be described. Further, error assessments were included with the input datasets, and we examine these in relation to inferred uncertainty in the optimized flux estimates in order to gauge our current ability to close the water budget within an expected uncertainty range.

  2. Science fiction/science fact: medical genetics in news stories.

    PubMed

    Petersen, Alan; Anderson, Alison; Allan, Stuart

    2005-12-01

    News media coverage of biotechnology issues offers a rich source of fictional portrayals, with stories drawing strongly on popular imagery and metaphors in descriptions of the powers and dangers of biotechnology. This article examines how science fiction metaphors, imagery and motifs surface in British newspaper (broadsheet and tabloid) coverage of medical genetic issues, focusing on press reporting of two recent highly publicised news media events; namely, the Hashmi and Whitaker families' plights to use stem cells from a 'perfectly matched sibling' for the treatment of their diseased children. It is concerned in particular with the extent to which journalists' use of certain literary devices encourages preferred formulations of medical genetics, and thereby potentially shapes public deliberation about scientific developments and their consequences for society. Understanding how science fiction sustains science fact, and vice versa, and how the former is portrayed in news media, it is argued, would thus seem to be crucial in the effort to understand why people respond so strongly to biotechnologies, and what they imagine their consequences to be.

    NIEDERDEPPE, JEFF; FROSCH, DOMINICK L.; HORNIK, ROBERT C.

    2010-01-01

    The shift toward viewing patients as active consumers of health information raises questions about whether individuals respond to health news by seeking additional information. This study examines the relationship between cancer news coverage and information seeking using a national survey of adults aged 18 years and older. A Lexis-Nexis database search term was used to identify Associated Press (AP) news articles about cancer released between October 21, 2002, and April 13, 2003. We merged these data to the Health Information National Trends Survey (HINTS), a telephone survey of 6,369 adults, by date of interview. Logistic regression models assessed the relationship between cancer news coverage and information seeking. Overall, we observed a marginally significant positive relationship between cancer news coverage and information seeking (p < 0.07). Interaction terms revealed that the relationship was apparent only among respondents who paid close attention to health news (p < 0.01) and among those with a family history of cancer (p < 0.05). Results suggest that a notable segment of the population actively responds to periods of elevated cancer news coverage by seeking additional information, but they raise concerns about the potential for widened gaps in cancer knowledge and behavior between large segments of the population in the future.

We describe a publicly available platform for monitoring vaccination-related content, called the Vaccine Sentimeter. With automated data collection from 100,000 mainstream media sources and Twitter, natural-language processing for automated filtering, and manual curation to ensure accuracy, the Vaccine Sentimeter offers a global real-time view of vaccination conversations online. To assess the system's utility, we followed two events: polio vaccination in Pakistan after a news story about a Central Intelligence Agency vaccination ruse and subsequent attacks on health care workers, and a controversial episode in a television program about adverse events following human papillomavirus vaccination. For both events, increased online activity was detected and characterized. For the first event, Twitter response to the attacks on health care workers decreased drastically after the first attack, in contrast to mainstream media coverage. For the second event, the mainstream and social media response was largely positive about the HPV vaccine, but antivaccine conversations persisted longer than the provaccine reaction. Using the Vaccine Sentimeter could enable public health professionals to detect increased online activity or sudden shifts in sentiment that could affect vaccination uptake. PMID:26858390

    This commentary overviews the look of health news in American print journalism and the research that suggests how health news creates influence at both the individual and policy levels. Crime and violence are argued to be public health issues, but unfortunately they are often not treated as such. There is clearly room for improvement in all areas of health news, but unfortunately the extreme stress that newspapers are under to maintain their high profit margins suggests that the resources for such improvement are unlikely to be available. Examination of the Minneapolis Star Tribune's coverage of health, crime and violence exemplifies problematic aspects. PMID:16464917

    This NASA Kennedy Space Center (KSC) video presents a Marshall Space Flight Center-Television (MSFC-TV) news release describing the objectives of the Atmospheric Laboratory for Applications in Science-2 (ATLAS-2), which is being flown on STS-56. Dr. Tim Miller (Mission Scientist), Dr. Marsha Torr (Mission Scientist), and Teresa Vanhooser (Mission Manager) explain that the ATLAS-2 mission is being launched to study earth atmospheric interactions with the sun in general and how manmade chemicals and pollution are contributing to ozone depletion in our atmosphere in particular. Seven instruments comprise the core payload. ATLAS-2 is an integral part of the Spacelab contribution to NASA's Mission to Planet Earth and characterizes the chemical and physical components of Earth's middle atmosphere and the solar energy injected in the atmosphere, studies that began on ATLAS-1.

    Allen Kenitzer, from Marshall Space Flight Center (MSFC), narrates this NASA Kennedy Space Center video presenting a MSFC-Television news release describing the overall scientific objectives of the Atmospheric Laboratory for Applications in Science-1 (ATLAS-1) Spacelab mission. Byron Lichtenberg (NASA Science Astronaut) and Anthony O'Neil (ATLAS-1 Mission Manager) explain that the 13 sophisticated and complementary instruments carried in shuttle Atlantis' payload bay are designed to identify the chemical species in our atmosphere, to measure the Sun's energy falling on and entering the atmosphere, to study the behavior of charged particles in the electric and magnetic fields surrounding the earth, and to gather ultraviolet light from stars and galaxies. ATLAS-1 is the first Spacelab flight of the National Aeronautics and Space Administration's (NASA's) Mission to Planet Earth.
