    The Internet is one of the fastest growing news sources for many worldwide (Pew Research Center's Project for Excellence in Journalism, 2011), and cancer news is one frequently consumed form of online health information (Google, Inc., 2007). This content analysis of online cancer news (n?=?862) retrieved from the four most frequented news websites describes trends regarding specific cancers, stages in the cancer continuum, and types of news articles. In general, treatment information received the most attention in online cancer news. Breast cancer received the most attention of each specific cancer, followed by digestive and genitourinary cancers. Research reports and profiles of people (more than 60% of which were about celebrities) were the most common article types. Risk, uncertainty, and clinical trials were also present across several types of cancer news articles. Implications of content trends are discussed as relevant to consumers, producers, health campaign designers, and researchers alike. PMID:23356571

  13. 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.

    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.

    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.

    2013-01-01

    The news media has substantial influence on public perceptions of social and health issues. This study conducted a video content analysis to examine portrayals of obese persons in online news reports about obesity. The authors downloaded online news videos about obesity (N = 371) from 5 major news websites and systematically coded visual portrayals of obese and nonobese adults and youth in these videos. The authors found that 65% of overweight/obese adults and 77% of overweight/obese youth were portrayed in a negative, stigmatizing manner across multiple obesity-related topics covered in online news videos. In particular, overweight/obese individuals were significantly more likely than were nonoverweight individuals to be portrayed as headless, with an unflattering emphasis on isolated body parts, from an unflattering rear view of their excess weight, eating unhealthy foods, engaging in sedentary behavior, and dressed in inappropriately fitting clothing. Nonoverweight individuals were significantly more likely to be portrayed positively. In conclusion, obese children and adults are frequently stigmatized in online news videos about obesity. These findings have important implications for public perceptions of obesity and obese persons and may reinforce negative societal weight bias. PMID:23421746

    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

    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.

  18. SciCentral: Gateway to the Best Scientific Research News Sources

    NSDL National Science Digital Library

    SciCentral will appeal to a wide variety of users interested or working in science or medicine. The site is first and foremost a gateway to thousands of online resources, grouped by science area (Biological, Health, Engineering, Physical & Chemical, etc.) and then subdivided by resource type (directories, specialized resources, databases, special reports, articles). SciCentral also features a number of diverse Special Features, including Academic Programs, K-12 Science, The Media Room, and a Bulletin Board, among others. Other resources include an internal search engine as well as links to science news wire search engines and science journal metasites. The site is quite large, and some users may feel overwhelmed at first, an impression not helped by the site's inclusion of several tangentially related resources. However, SciCentral's real appeal is what sets it apart from other science metasites: its strength as a current awareness resource, with links to current research highlights, breaking science news, and new articles from an impressive range of sources. In addition, the site has recently introduced a free customizable weekly science e-mail update service, which allows users to select from over 120 topics.

    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.

  1. 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.

    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

  14. An Online Platform for Resources and Collaborative Research on Earthquake Source

    NASA Astrophysics Data System (ADS)

    Thingbaijam, K. S.; Mai, P. M.

    2013-12-01

    We develop the online platform http://equake-rc.info for collaborative research on earthquake sources. The platform has three main features: (1) finite-fault earthquake source models (SRCMOD) database, (2) Source Inversion Validation (SIV) Benchmarks and its Wiki, and (3) software Codes for Earthquake Rupture and ground-motion Simulation (CERS). 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.

In addition, it can deliver any information, such as "news, weather, stocks, database records, ads, audio files, video clips, etc. that can be served up on a Web page accessible by intended subscribers." What really sets it apart, however, is an open publishing model that allows any source to establish channels using industry standard file formats and Desktop News's specifications. While the major online news providers are, of course, represented on Desktop News, this model seems to offer the potential for a news democratization of sorts, with the possibility of a range and depth of content not found in most current awareness tools. After downloading, users have a number of options for customizing their channels and ticker display settings. They can then visit the site to automatically add other channels. Free registration is requested, but it does not appear to be required.

  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.

  8. Incremental visual text analytics of news story development

    NASA Astrophysics Data System (ADS)

    Krstajic, Milos; Najm-Araghi, Mohammad; Mansmann, Florian; Keim, Daniel A.

    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.

  12. Ontology acquisition from on-line knowledge sources.

    PubMed

    Li, Q; Shilane, P; Noy, N F; Musen, M A

    2000-01-01

    Electronic knowledge representation is becoming more and more pervasive both in the form of formal ontologies and less formal reference vocabularies, such as UMLS. The developers of clinical knowledge bases need to reuse these resources. Such reuse requires a new generation of tools for ontology development and management. Medical experts with little or no computer science experience need tools that will enable them to develop knowledge bases and provide capabilities for directly importing knowledge not only from formal knowledge bases but also from reference terminologies. The portions of knowledge bases that are imported from disparate resources then need to be merged or aligned to one another in order to link corresponding terms, to remove redundancies, to resolve logical conflicts. We discuss the requirements for ontology-management tools that will enable interoperability of disparate knowledge sources. Our group is developing a suite of tools for knowledge-base management based on the Protégé-2000 environment for ontology development and knowledge acquisition. We describe one such tool in detail here: an application for incorporating information from remote knowledge sources such as UMLS into a Protégé knowledge base. PMID:11079933

    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. Aw

  17. On-line He-cryostat for Mössbauer spectroscopy with short-lived radioactive sources

    NASA Astrophysics Data System (ADS)

    Trautmannsheimer, M.; Komninos, P.; Huenges, E.; Morinaga, H.

    1993-12-01

    A special on-line He-cryostat for Mössbauer spectroscopy with accelerator-produced radioactive sources was developed. The design of this cryostat allows a computer-controlled irradiation of different targets and the fast transport of these sources to the absorber. Therefore, this setup is suitable for Mössbauer spectroscopy even with very short-lived sources. The sources are cooled down to 15 K by a cryogenerator capable of absorbing a beam power of 10 W in this temperature range. The liquid helium-cooled absorber is moved by a piezoelectric drive unit. Using this cryostat the sharp resonance of the Mössbauer effect in 63Ni was observed for the first time. In this experiment data from more than 1500 63Co sources (T {1}/{2} = 27 s) have been collected.

    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

    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.

    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.

  2. 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

  3. OxMaR: Open Source Free Software for Online Minimization and Randomization for Clinical Trials

    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.

    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.

      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.

    • Hot News Recommendation System from Heterogeneous Websites Based on Bayesian Model

      PubMed Central

      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

    2013-06-01

    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.

    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.

    Today, participatory or citizen journalism - journalism which enables readers to become writers - exists online and offline in a variety of forms and formats, operates under a number of editorial schemes, and focuses on a wide range of topics from the specialist to the generic and the micro-local to the global. Key models in this phenomenon include veteran sites Slashdot and Indymedia, as well as news-related weblogs; more recent additions into the mix have been the South Korean OhmyNews, which in 2003 was “the most influential online news site in that country, attracting an estimated 2 million readers a day” (Gillmor, 2003a, p. 7), with its new Japanese and international offshoots, as well as the Wikipedia with its highly up-to-date news and current events section and its more recent offshoot Wikinews, and even citizen-produced video news as it is found in sites such as YouTube and Current.tv.

    NSDL National Science Digital Library

    It's not an understatement to say that mainstream news in the United States has been in a bit of a tizzy in recent years, with a number of journalists serving time for refusing to reveal their sources and other such activities. The times seem right for an investigative report into the challenges facing the news media, and Frontline has stepped forward with a very fine four-part series on the subject. Visitors to the site can watch the program in its entirety here, but before doing so, they may wish to read the introductory essay which can be found from the homepage. As might be expected, the site contains a number of nice extras, including a place to submit feedback, a teacher's guide, and reactions from the press regarding the series. For visitors pressed for time, there is also the option to look over selected interviews from the series in the "Interviews" area. There are over 50 journalists profiled here, and visitors can view an alphabetical list, or take a look at some topical responses organized into sections such as "The Future of the News" and "The Internet and New Media". Broad in its scope and conforming to the rigorous standards of the Frontline series, this program and its accompanying website should be "required reading" for all journalists and journalism students.

    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

    This article examines how the news production process affects the presentation of crime in the news media. Content analysis and ethnographic methods were used to determine the types of crime presented. The media rely heavily on criminal justice sources for crime story information; this reliance influences the type of stories selected and how they are presented to the public. The

  2. VizieR Online Data Catalog: WMAP point sources at 61 and 94GHz (Lanz+, 2013)

    NASA Astrophysics Data System (ADS)

    Lanz, L. F.; Herranz, D.; Lopez-Caniego, M.; Gonzalez-Nuevo, J.; de Zotti, G.; Massardi, M.; Sanz, J. L.

    2014-02-01

    The detection of point sources in cosmic microwave background maps is usually based on a single-frequency approach, whereby maps at each frequency are filtered separately and the spectral information on the sources is derived combining the results at the different frequencies. In contrast, in the case of multifrequency detection methods, source detection and spectral information are tightly interconnected in order to increase the source detection efficiency. In this work we apply the matched multifiltermethod to the detection of point sources in the Wilkinson Microwave Anisotropy Probe (WMAP) 7-year data at 61 and 94GHz. This linear filtering technique takes into account the spatial and the cross-power spectrum information at the same time using the spectral behaviour of the sources without making any a priori assumption about it.

  3. 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.

  6. VizieR Online Data Catalog: WISE candidate ?-ray blazar radio sources (D'Abrusco+, 2014)

    NASA Astrophysics Data System (ADS)

    D'Abrusco, R.; Massaro, F.; Paggi, A.; Smith, H. A.; Masetti, N.; Landoni, M.; Tosti, G.

    2015-01-01

    We present a catalog of radio-loud candidate ?-ray emitting blazars with WISE mid-infrared colors similar to the colors of confirmed ?-ray blazars. The catalog is assembled from WISE sources detected in all four WISE filters, with colors compatible with the three-dimensional locus of the WISE ?-ray emitting blazars, and which can be spatially cross-matched with radio sources from one of the three radio surveys: NVSS, FIRST, and/or SUMSS. Our initial WISE selection uses a slightly modified version of previously successful algorithms. We then select only the radio-loud sources using a measure of the radio-to-IR flux, the q22parameter, which is analogous to the q24 parameter known in the literature but which instead uses the WISE band-four flux at 22?m. Our final catalog contains 7855 sources classified as BL Lacs, FSRQs, or mixed candidate blazars; 1295 of these sources can be spatially re-associated as confirmed blazars. We describe the properties of the final catalog of WISE blazar-like radio-loud sources and consider possible contaminants. Finally, we discuss why this large catalog of candidate ?-ray emitting blazars represents a new and useful resource to address the problem of finding low-energy counterparts to currently unidentified high-energy sources.

    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).

    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

    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).

  20. Basic studies of a gas-jet-coupled ion source for on-line isotope separation

    SciTech Connect

    Anderl, R.A.; Novick, V.J.; Greenwood, R.C.

    1980-01-01

    A hollow-cathode ion source was used in a gas-jet-coupled configuration to produce ion beams of fission products transported to it from a /sup 252/Cf fission source. Solid aerosols of NaCl and Ag were used effectively as activity carriers in the gas-jet system. Flat-plate skimmers provided an effective coupling of the ion source to the gas jet. Ge(Li) spectrometric measurements of the activity deposited on an ion-beam collector relative to that deposited on a pre-skimmer collector were used to obtain separation efficiencies ranging from 0.1% to > 1% for Sr, Y, Tc, Te, Cs, Ba, Ce, Pr, Nd and Sm. The use of CCl/sub 4/ as a support gas resulted in a significant enhancement of the alkaline-earth and rare-earth separation efficiencies.

  1. Resonance ionization laser ion sources for on-line isotope separators (invited)

    NASA Astrophysics Data System (ADS)

    Marsh, B. A.

    2014-02-01

    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.

    Flux densities at 15.7GHz, 1.4GHz and 610MHz along with radio spectral indices are given for 296 sources selected at 15.7GHz from the Lockman Hole fields of the Tenth Cambridge (10C) survey (AMI Consortium: Davies et al. 2011, Cat. J/MNRAS/415/2708, AMI Consortium: Franzen et al. 2011MNRAS.415.2699F). All 610-MHz flux densities come from the GMRT survey by Garn et al. (2008, Cat. J/MNRAS/387/1037, 2010, Cat. J/other/BASI/38.103). For extended sources the original images have been smoothed to a comparable resolution to the 10C survey (30-arcsec) before the flux density is extracted to make the flux densities at 15.7GHz and 610MHz more directly comparable. For 10C sources without a counterpart in the GMRT image, three times the local noise is included as an upper limit on the flux density at 610MHz. For these sources, the value of the column 'f_S610' is 1 (meaning the value in 'S610' is an upper limit, not a detection). Five sources lie outside the GMRT survey area so 610MHz data is not available for these sources. The 1.4-GHz flux density values come from a number of different catalogues, in the following order of preference: NVSS, FIRST, WSRT catalogue (Guglielmino et al. 2012, in prep), Owen and Morrison (2008, Cat. J/AJ/136/1889), Biggs and Ivison (2008, Cat. J/MNRAS/371/963), upper limit from WSRT catalogue the upper limit from FIRST. The value of 'f_S1.4best' indicates which catalogue the 1.4-GHz flux density value originates from. 1.4-GHz values are also included using NVSS values only - in this case, for 10C sources without a counterpart in the NVSS catalogue an upper limit of three times the local noise in the NVSS map was placed on the 1.4-GHz flux density. The value of 'f_SNVSS' indicates whether the flux density value is an upper limit (1) or a detection (0). The relevent radio spectral indices are also included. Note that this catalogue contains sources which are not in the original 10C catalogue as they are below the completeness limit. (1 data file).

    Reverberation and noise cause significant deterioration of audio quality and intelligibility to signals recorded in acoustic environments. Noise is usually modeled as a common signal observed in the room and independent of room acoustics. However, this simplistic model cannot necessarily capture the effects of separate noise sources at different locations in the room. This paper proposes a noise model that

    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).

    A highly-selective resonant ionization laser ion source has been successfully commissioned at the Holifield Radioactive Ion Beam Facility, Oak Ridge National Laboratory, for the production of pure beams of short-lived nuclei for spectroscopic studies. The laser ion source provided beams of neutron-rich Ga isotopes to the Low-energy Radioactive Ion Beam Spectroscopy Station for beta decay measurements. The radioactive Ga isotopes were produced by 50-MeV proton induced fission of 238U and ionized by laser radiation using a two-step resonant ionization scheme. Isobarically pure 83Ga, 85Ga, and 86Ga beams were delivered to the experiment at approximate rates of 12000 ions/s, 100 ions/s, and 3 ions/s, respectively.

    2014-10-01

    The selection of the sample was based on the list of confirmed AT20G sources available at the epoch of our observations (2006 October). We selected all objects with flux density S20GHz>500mJy and declination DE<-30°, excluding the Galactic plane region (|b|<=1.5°) and the Large Magellanic Cloud (LMC) region (inside a circle of 5.5° radius centred at RA=05:23:34.7 and DE=-69:45:22). This resulted in a complete sample of 189 sources. The observations were taken on October 1, 2006 using the most compact hybrid configuration of ATCA, H75, excluding the data from the farthest antenna. The longest baseline of this configuration is 75m, and its T-shape ensures adequate Fourier coverage for snapshots taken on a relatively small range of hour angles and at high elevation.

    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).

    We have assembled a low-frequency radio catalog of flat-spectrum sources (LORCAT) built by combining the radio observations of the two main Westerbork Synthesis Radio Telescope (WSRT) surveys (i.e., WENSS and WISH) at 325MHz and 352MHz, respectively, with those of the NVSS at 1.4GHz. The WENSS is a low-frequency radio survey that covers the northern sky above +30° in declination performed at 325MHz to a limiting flux density of ~18mJy at the 5? level (Rengelink et al. 1997, Cat. J/A+AS/124/259, superseded by VIII/62). The version of the WENSS catalog used in our analysis was implemented as a combination of two separate catalogs obtained from the WENSS Web site: the WENSS Polar Catalog that comprises 18186 sources above +72° in declination and the WENSS Main Catalog including 211234 objects in the declination range between +28° and +76°. We also used the WISH catalog (Cat. VIII/69), which is the southern extension of the WENSS. WISH is a low-frequency (352MHz) radio survey covering most of the sky between -26° and -9° to the same limiting flux density of the WENSS. (1 data file).

    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 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.

    2009-06-01

    The Galactic Legacy Infrared Midplane Survey Extraordinaire (GLIMPSE), is a survey of Galactic Plane central parts made with the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope (SST). It covers approximately 220 square degrees, between galactic longitudes +/-65° and +/-1° in galactic latitude (up to 4.2° in the central parts). The four IRAC bands are centered at approximately 3.6, 4.5, 5.8 and 8.0?m. The GLIMPSE combines the 3 surveys: * GLIMPSE-I covers the longitude ranges |l|=10--65° and the latitude range |b|<=1° (Benjamin et al. 2003PASP..115..953B) * GLIMPSE-II covers the longitude range of |l|<=10°, and a latitude range |b|<=1° from |l|=5--10, |b|<=1.5 for |l|=2--5, and |b|<=2° for |l|<=2. GLIMPSE-II coverage excludes the Galactic center region |l|<=1, |b|<=0.75 observed by the GALCEN GO program (PID=3677). * GLIMPSE-3D adds vertical extensions up to |b|=4.2° near the galactic center, and up to |b|=3° in selected other parts of the Galaxy (+/-10, 18.5, 25, 30, and -15 (345)°). GLIMPSE-II had two-epoch coverage for a total of three visits on the sky. The observations consisted of two 1.2 second integrations at each position in the first epoch of data taking (September 2005) and a single 1.2 second integration at each position six months later (April 2006). The highly reliable v2.0 GLIMPSEII Catalog (v2.0_GLMIIC) consists of point sources that are detected at least twice in one band and at least once in an adjacent band and a S/N > 5 cut for the band with the two detections. There are also faint and bright flux limits on the Catalog entries. The more complete v2.0 Archive (v2.0_GLMIIA) has less stringent criteria, namely two detections in any bands, those detections having a S/N > 5. The IRAC data were bandmerged with the 2MASS All-Sky Point Source Catalog. See the GLIMPSEII v2.0 Data Products & Data Delivery document for more details. The catalog available from CDS merges the 3 surveys GLIMPSE-I (v2.0), GLIMPSE-II (v2.0), and GLIMPSE-3D; Catalog and Archive records are also merged here. In the regions of overlap between the 3 surveys (e.g. longitude around 10°) preference was given to (1) GLIMPSE-II, as recommended in the GLIMPSE documents of May 2007 (glimpse1_v2.0.pdf) and April 2008 (glimpse2-v2.0.pdf); (2) GLIMPSE-I, and (3) GLIMPSE-3D sources. Sources from different surveys were merged if their position is closer than 0.1arcsec.

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

  10. 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.

    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 Ly?-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).

  14. On-Line Desalting of Crude Oil in the Source Region of a Fourier Transform Ion Cyclotron Resonance Mass Spectrometer

    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 pKa; 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.

    The rapid assimilation data and information on the Internet and the World Wide Web (WWW) is reflected in the development of these electronic services by state, county, local, and other subnational agencies, departments, offices, bureaus, and intergovernmental bodies. The content of state and territorial, tribal, county, and local government Web pages varies considerably. However, information about health and the environment are among the most frequently posted resources by subnational government bodies. This article describes the environmental health and toxicology-related data and information resources provided by government agencies and representative associations for subnational government bodies. Standard reference sources for identifying subnational government bodies are described with particular reference to those in electronic and digital formats. Means for identifying and locating electronic resources are described for appropriate subnational environmental quality, environmental (public) health agencies, occupational health and safety, toxicology-related agencies and departments, emergency response, fish consumption advisories, and cancer registries are provided. Professional organizations of state, county, municipal (local) governments and intergovernmental bodies are also described. PMID:11164974

    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).

    The 2009 monitoring campaign of M82 consisted of seven wide-field MERLIN (Thomasson 1986) observations at a frequency of 4.994GHz, observed between 2009 May and 2010 April. These were made using parallel hands of circular polarization, and were correlated with a total bandwidth of 16 MHz divided into 32 channels. Across all epochs combined a total on-source integration time of 286.5h was used. Each observing epoch was reduced and analysed individually and a deep exposure map was produced by combining all of these data. In addition to these, a single e-MERLIN observation was included in this study. This observation was made in 2010 December as part of the e-MERLIN commissioning programme and used a total bandwidth of 512MHz with a median frequency of 6.26GHz. These data were correlated into four individual sub-bands each divided into 512 frequency channels. These e-MERLIN observations were observed prior the installation of the new e-MERLIN wide-band IF system in spring 2011 and consequently only one hand of polarization was used and the data displayed reduced sensitivity in parts of the observing band.

    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.

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.

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).

    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.

    2006-01-01

    At the ISOLDE on-line isotope separation facility, the resonance ionization laser ion source (RILIS) can be used to ionize reaction products as they effuse from the target. The RILIS process of laser step-wise resonance ionization of atoms in a hot metal cavity provides a highly element selective stage in the preparation of the radioactive ion beam. As a result, the ISOLDE mass separators can provide beams of a chosen isotope with greatly reduced isobaric contamination. The number of elements available at RILIS has been extended to 26, with the addition of a new three-step ionization scheme for gold. The optimal ionization scheme was determined during an extensive study of the atomic energy levels and auto-ionizing states of gold, carried out by means of in-source resonance ionization spectroscopy. Details of the ionization scheme and a summary of the spectroscopy study are presented.

    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 (14)O (71 s), (42)K (12.4 h), (43)K (22.2 h), and (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(3) particles per second (pps). About 3.2 × 10(3) pps of 1.4 MeV (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. PMID:23556809

    For the second consecutive year, AGU has published Geophysics News, a collection of short articles about new research findings from the past year. The primary target for this publication is science journalists, who can make constructive use of clearly written, accessible stories by spreading them to an even wider audience. The special spin on articles in Geophysics News is that research findings are placed in their proper scientific perspective with relevant policy implications described as well.The full contents of Geophysics News 1991 will be run in Eos over the next several weeks, beginning with this issue. This is being done for two reasons. First, these articles present AGU members with a wonderful opportunity to learn about the “hot news” in research areas outside of their own expertise. And, as examples of science writing for a broad audience, these articles are meant to encourage other AGU members to also make the effort to write about their science for the general public.

  12. Breaking bad news.

    PubMed

    VandeKieft, G K

    2001-12-15

    Breaking bad news is one of a physician's most difficult duties, yet medical education typically offers little formal preparation for this daunting task. Without proper training, the discomfort and uncertainty associated with breaking bad news may lead physicians to emotionally disengage from patients. Numerous study results show that patients generally desire frank and empathetic disclosure of a terminal diagnosis or other bad news. Focused training in communication skills and techniques to facilitate breaking bad news has been demonstrated to improve patient satisfaction and physician comfort. Physicians can build on the following simple mnemonic, ABCDE, to provide hope and healing to patients receiving bad news: Advance preparation--arrange adequate time and privacy, confirm medical facts, review relevant clinical data, and emotionally prepare for the encounter. Building a therapeutic relationship-identify patient preferences regarding the disclosure of bad news. Communicating well-determine the patient's knowledge and understanding of the situation, proceed at the patient's pace, avoid medical jargon or euphemisms, allow for silence and tears, and answer questions. Dealing with patient and family reactions-assess and respond to emotional reactions and empathize with the patient. Encouraging/validating emotions--offer realistic hope based on the patient's goals and deal with your own needs. PMID:11775763

  13. Popularity and Quality in Social News Aggregators: A Study of Reddit and Hacker News

    E-print Network

    Stoddard, Greg

    2015-01-01

    In this paper we seek to understand the relationship between the online popularity of an article and its intrinsic quality. Prior experimental work suggests that the relationship between quality and popularity can be very distorted due to factors like social influence bias and inequality in visibility. We conduct a study of popularity on two different social news aggregators, Reddit and Hacker News. We define quality as the relative number of votes an article would have received if each article was shown, in a bias-free way, to an equal number of users. We propose a simple poisson regression method to estimate this quality metric from time-series voting data. We validate our methods on data from Reddit and Hacker News, as well the experimental data from prior work. This method works well even though the collected data is subject to common social media biases. Using these estimates, we find that popularity on Reddit and Hacker News is a stronger reflection of intrinsic quality than expected.

  17. 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.

  1. Heated Debates Over Open Source Software

    NSDL National Science Digital Library

    Open source code has allowed for the proliferation of open source software that competes with the big guns of software development, like Microsoft. Tempers run high, with the key issues focused on differing philosophies on the best business model to use and disputes over copyright, leading to lawsuits and heated online discussions. This issue of Topic in Depth provides an overview of open source software, and a selection of websites that discuss some of the pros and cons to the different approaches to software development.Some argue that open source is the best way to improve software, because developers can share the code and discuss issues. This article from _Nature_ reviews some of those arguments (1). Slashdot.com posts this article, which offers a counter argument (2) by raising concerns about security. Security has been a key issue for Microsoft -- along with copyright -- and it posts this statement on the company website regarding its "Approach to Source Code Sharing Balances Accessibility with Responsibility" (3).More information on copyright issues can be found on the GNU Project website (4 ). The GNU project was initiated by Richard Stallman and sponsored by the Free Software Foundation, which "supports the freedoms of speech, press, and association on the Internet, the right to use encryption software for private communication, and the right to write software unimpeded by private monopolies." The Open Source Initiative (OSI) emphasizes the management and promotion of the Open Source Definition "for the good of the community" and provides some basic information on open source software (5 ). Another online news source on open source software -- Daemon News(6 )-- posts an article that argues for other ways open source can be a learning tool in "Teaching Kids to Think for Themselves." This website provides a brief history of open source software (7), tracing the initiation of open source software to Stallman and his colleagues during "the 'hacker' culture of U.S. computer science laboratories." For more on the extent of open source software now available, see O'Reilly's list of resources (8 ).

  2. 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

    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???m 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.

  7. The Internet as a Resource for News and Information about Science

    NSDL National Science Digital Library

    2006-01-01

    Americans get quite a bit of information from the Internet, and if recent surveys are any indication, they also seem to spend quite a bit of time browsing around the web as part of their day. This 42-page report from the Pew Internet & American Life Project released in November 2006 confirms that Americans also tend to use the Internet as a way to research various scientific subjects and related news items. The report was jointly conducted with the assistance of the San Francisco-based Exploratorium, and revealed that fully 40 million Americans use the Internet as their "primary source of news and information about science." The report contains a number of other interesting findings, including the observation that 87% of online users have used the Internet to look up the meaning of a scientific concept, answer a specific science question, or check the accuracy of a scientific fact. The report will certainly be very useful to science educators and those concerned with information science and related topics.

  11. Business Advice Online

    NSDL National Science Digital Library

    Business Advice Online is a creation of the Small Business Service (SBS), a new government agency in the United Kingdom. Launched in April 2000, the Website highlights some of the excellent resources available through this agency in the Business Topics section. Clicking on a topic brings up a subtopic menu, which in turn leads to short synopses of SBS services and hyperlinks to other UK government documents. Users be forewarned that the links are a little hard to see because the main text is dark blue and the links are in black font. The site also contains links to other industry information, business news, and key contacts. Another slight flaw in the design of the site is that some of the subtopic menus pop-up very low in the screen, so users may have to scroll down a bit to see the menus. However, these small problems should not overshadow the wealth of information found on Business Advice Online.

    2012-02-01

    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.

  14. VizieR Online Data Catalog: mJy radio sources at 1.4 GHz (Lu+ 1996)

    NASA Astrophysics Data System (ADS)

    Lu, N. Y.; Hoffman, G. L.; Salpeter, E. E.; Houck, J. R.

    1998-04-01

    From the 1.4GHz radio survey of Condon, Dickey, & Salpeter (Cat. ) in a region much devoid of rich galaxy clusters at redshifts z<0.43 we selected a "distant" sample of 57 radio sources complete to a 1.4GHz flux density of 35mJy and a "nearby" sample of 36 mostly weaker radio sources which are optically brighter than B~19mag. Our ultimate goals are (1) to study the radio, optical, and near-IR properties of those high-redshift (z~1), moderate-power radio sources in the distant sample and to compare them with that of more powerful radio sources, and (2) to make a comparison of primarily noncluster radio sources in the nearby sample with a companion survey of radio sources in a pair of rich superclusters at z~0.1. In this first paper of a series, we report our new C-array VLA continuum snapshots at 4.86GHz and optical R-band CCD imaging photometry for these two samples and tabulate the observational results on individual sources. Some direct sample statistical properties are also discussed in the paper and summarized as follows: (1) The distant sample: (a) The sample median flux density at 1.4GHz is about 65mJy. (b) The majority (80%) of the sample sources have a steep spectrum between 1.4 and 4.86GHz with a spectral index around 0.9. Nineteen (90%) of the 21 sources that are fully resolved at 4.86 GHz (i.e., angular sizes ?>11") have a radio morphology of Fanaroff-Riley (FR) II type. (c) Thirty-seven (88%) of the 42 optically imaged sample sources were optically identified to a limiting R-band magnitude of R~23.5mag. About 15% of the identified radio sources appear to be point sources, and the others are extended galaxies with an appearance similar to nearby elliptical galaxies. (d) Twenty-eight (76%) of the optically identified sources have R>20mag, suggesting that these are probably distant (z>0.8), with a redshift distribution peaking at z~1, where their radio luminosities are about 10 times the break power between the FR I and II classes. (e) We found no strong evidence for the radio and optical axes of the resolved radio sources (i.e., ?>5") to be correlated or anticorrelated, nor any evidence for strong clustering around sample radio sources on average. (2) The nearby sample: except for R<15, the sample is dominated by elliptical galaxies with 16source, we found that the average radio source environment becomes richer from that characteristic of galaxy groups for R<17mag (z<0.2) to that of galaxy groups to clusters at R>18mag (z>0.3) .

    For this activity students read the newspaper on a daily basis, listen to news on the radio, or watch television, to acquire material related to the earth sciences. They will look for natural hazards (earthquakes, volcanoes, landslides, hurricanes, etc.), human-made hazards (urbanization, compromised engineering projects, etc.), environmental issues, or resource extraction issues which all appear in the news with great frequency and are easily accessible. Students are reminded that they should look for information on the local level (water quality, solid waste management, development issues, etc.), as well as national and world wide issues. The news items may then be presented to the class as show-and-tell exercises with follow-up discussion by the class; a bulletin board that could be dedicated to posting the geologic events of the week; or scrapbooks of events, arranged either chronologically or by category of events compiled by individuals or classes.

    A leading national newspaper has stated that the majority of the information contained in its pages is in the form of advertisements. To investigate this, portions of the local newspaper are distributed to students working in groups. The class first reaches consensus on their definitions of "news" and other general headings (sports, entertainment, etc.). Students then express the ratio of the area of each category to the area of the page as a fraction and decimal. After analyzing the entire newspaper, students decide how much of it is really news.

    Following its launch in 2008 June, the Fermi Gamma-ray Space Telescope (Fermi) began a sky survey in August. The Large Area Telescope (LAT) on Fermi in three months produced a deeper and better resolved map of the ?-ray sky than any previous space mission. We present here initial results for energies above 100MeV for the 205 most significant (statistical significance greater than ~10?) ?-ray sources in these data. These are the best characterized and best localized point-like (i.e., spatially unresolved) ?-ray sources in the early mission data. (1 data file).

    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

    With complicated climatic and topographic conditions as well as improper human activities, soil erosion and non-point source pollution are widely distributed and of high intensity in the mountainous Three-gorge Reservoir Area. Especially owing to the Three-gorge Project's different operation schemes, the water levels vary dramatically and the hydro-fluctuation belt area has become a special ecological vulnerable area.

    2008-12-01

    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.

    We present light curves for 149 sources monitored with the Green Bank Interferometer. The light curves are at two radio frequencies (approximately 2.5 and 8.2GHz) and range from 3 to 15yr in length, covering the interval 1979-1996, and have a typical sampling of one flux density measurement every 2 days. Observations were made on a 2.4km baseline. Dual circular polarization was recorded over a 35MHz bandwidth at two frequencies in the S and X frequency bands. Until 1989 August (1989.7), the frequencies were 2.7GHz (S band) and 8.1GHz (X band); in 1989 September cryogenic receivers were installed, and the frequencies changed to 2.25GHz (S band) and 8.3GHz (X band).

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?

  5. Youth and violence on local television news in California.

    PubMed Central

    Dorfman, L; Woodruff, K; Chavez, V; Wallack, L

    1997-01-01

    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.

  8. Automated vocabulary discovery for geo-parsing online epidemic intelligence

    PubMed Central

    2009-01-01

    Background Automated surveillance of the Internet provides a timely and sensitive method for alerting on global emerging infectious disease threats. HealthMap is part of a new generation of online systems designed to monitor and visualize, on a real-time basis, disease outbreak alerts as reported by online news media and public health sources. HealthMap is of specific interest for national and international public health organizations and international travelers. A particular task that makes such a surveillance useful is the automated discovery of the geographic references contained in the retrieved outbreak alerts. This task is sometimes referred to as "geo-parsing". A typical approach to geo-parsing would demand an expensive training corpus of alerts manually tagged by a human. Results Given that human readers perform this kind of task by using both their lexical and contextual knowledge, we developed an approach which relies on a relatively small expert-built gazetteer, thus limiting the need of human input, but focuses on learning the context in which geographic references appear. We show in a set of experiments, that this approach exhibits a substantial capacity to discover geographic locations outside of its initial lexicon. Conclusion The results of this analysis provide a framework for future automated global surveillance efforts that reduce manual input and improve timeliness of reporting. PMID:19930702

  9. People’s trust in health news disseminated by mass media in Tehran

    PubMed Central

    Nedjat, Sima; Nedjat, Saharnaz; Majdzadeh, Reza; Farshadi, Mojgan

    2014-01-01

    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

  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 ?g/L for TTHM and 60 ?g/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.

    This study investigates the processes by which competition in the television news market might promote the presence of arousing characteristics in television news. A total of 3,024 news stories from six Dutch television news programs over the period 1990 to 2004 were investigated through content analysis. The findings of the study show overall increases in all 6 arousing characteristics. The

  13. 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.

Of course, this wasn't recent by human standards - the Eocene epoch during which these temperatures were the norm occurred about 55 to 48 million years ago. However, this finding may provide insight into how Earth's climate responds to variable levels of atmospheric carbon dioxide. In addition, it allows us to imagine a world very different from the one we know: one in which palm trees flourished at latitudes that today reach summer highs of about 8 C and sink to lows of -50 C.The first link takes visitors to a blog entry outlining some of the article's discoveries, including detailed descriptions of the ecosystem. The second leads to an article featuring an interview with one of the study's co-authors that describes both the procedures and findings. Interested parties may want to read the original Nature article itself, accessible via the third link. Bringing us into the modern era, the fourth link leads to an article reflecting on the complicated relationship between the outside world and those overwintering in Antarctica. The fifth allows visitors to explore facts and figures about the United States presence in Antarctica, featuring some great webcam feeds. Finally, the last link leads to a magnificent collection of images and videos of the now-frozen continent.
