    The EVA Wiki was recently implemented as the primary knowledge database to retain critical knowledge and skills in the EVA Operations group at NASA's Johnson Space Center by ensuring that information is recorded in a common, easy to search repository. Prior to the EVA Wiki, information required for EVA flight controllers and instructors was scattered across different sources, including multiple file share directories, SharePoint, individual computers, and paper archives. Many documents were outdated, and data was often difficult to find and distribute. In 2011, a team recognized that these knowledge management problems could be solved by creating an EVA Wiki using MediaWiki, a free and open-source software developed by the Wikimedia Foundation. The EVA Wiki developed into an EVA-specific Wikipedia on an internal NASA server. While the technical implementation of the wiki had many challenges, one of the biggest hurdles came from a cultural shift. Like many enterprise organizations, the EVA Operations group was accustomed to hierarchical data structures and individually-owned documents. Instead of sorting files into various folders, the wiki searches content. Rather than having a single document owner, the wiki harmonized the efforts of many contributors and established an automated revision controlled system. As the group adapted to the wiki, the usefulness of this single portal for information became apparent. It transformed into a useful data mining tool for EVA flight controllers and instructors, as well as hundreds of others that support EVA. Program managers, engineers, astronauts, flight directors, and flight controllers in differing disciplines now have an easier-to-use, searchable system to find EVA data. This paper presents the benefits the EVA Wiki has brought to NASA's EVA community, as well as the cultural challenges it had to overcome.

  4. WikiD : A WikiEngine Supporting Structured Data

    CERN. Geneva; Young, Jeffrey

    2005-01-01

    Ward Cunningham describes a wiki as "the simplest online database that could possibly work". The cost of this simplicity is that wikis are generally limited to a single collection containing a single kind of record (viz. WikiMarkupLanguage records). WikiD extends the Wiki model to support multiple collections containing arbitrary schemas of XML records with minimal additional complexity. WikiD is essentially a lightweight framework combining: * Open-source implementations of various loosely-coupled open-standard protocols (e.g. OpenURL, SRW/U, SRW Update, OAI-PMH, RSS) * An open-source version-controlled database. * A set of bootstrap collections. * XSL Stylesheets to render collection-level open-standard protocol responses into HTML for human consumption. Automated processes can ignore the stylesheet reference and use the open-standard protocol responses directly. Possible applications for WikiD include collaborative maintenance of registries, thesauri, taxonomies, reviews, and documentation. In addition to ...

    Full Text Available Wikis have recently been adopted to support a variety of collaborative activities within libraries. This article and its companion wiki, LibraryWikis (http://librarywikis.pbwiki.com/, seek to document the phenomenon of wikis in libraries. This subject is considered within the framework of computer-supported cooperative work (CSCW. The author identified thirty-three library wikis and developed a classification schema with four categories: (1 collaboration among libraries (45.7 percent; (2 collaboration among library staff (31.4 percent; (3 collaboration among library staff and patrons (14.3 percent; and (4 collaboration among patrons (8.6 percent. Examples of library wikis are presented within the article, as is a discussion for why wikis are primarily utilized within categories I and II and not within categories III and IV. It is clear that wikis have great utility within libraries, and the author urges further application of wikis in libraries.

    2014-01-21

    In 2008, WhatisKT wiki was launched as a collaborative platform for knowledge translation (KT) researchers and stakeholders to debate the use and definitions of KT-related terms. The wiki has definitions for over 110 terms from disciplines including health care, information technology, education, accounting, and business. WhatisKT wiki has over 115 registered users. Approximately 73,000 unique visitors have visited the wiki since 2008. Despite annual increases in visitors and regular maintenance of the wiki, no visitors have contributed content or started a discussion. We surveyed wiki users to gain an understanding of the perceived value of the website, reasons for not engaging in the wiki, and suggestions to facilitate collaboration and improve the usability of the wiki. We surveyed three cohorts: KT Canada members who were previously invited to join the wiki, registered wiki members, and unregistered visitors. The first two cohorts completed a Web-based survey that included the System Usability Scale (SUS) questionnaire to assess usability; additionally 3 participants were interviewed. Unregistered wiki visitors were surveyed with polls posted on the wiki. The study received ethics approval from the McMaster University Faculty of Health Sciences Research Ethics Board. Twenty-three participants completed the Web-based and SUS surveys; 15 participants indicated that they would collaborate on the wiki. The mean SUS score of 67 (95% CI 56-77) indicated that the wiki could be considered for design improvements. Study participants indicated that the wiki could be improved by email notification regarding new terms, better grouping of terms, user friendly interface, and training for users interested in editing content. The findings from this survey will be used to enhance the design and content of WhatisKT wiki. Further feedback from participants will be used to make the wiki an ideal collaboration platform for KT researchers interested in terminology.

  8. Biological knowledge bases using Wikis: combining the flexibility of Wikis with the structure of databases.

    2010-09-01

    In recent years, the number of knowledge bases developed using Wiki technology has exploded. Unfortunately, next to their numerous advantages, classical Wikis present a critical limitation: the invaluable knowledge they gather is represented as free text, which hinders their computational exploitation. This is in sharp contrast with the current practice for biological databases where the data is made available in a structured way. Here, we present WikiOpener an extension for the classical MediaWiki engine that augments Wiki pages by allowing on-the-fly querying and formatting resources external to the Wiki. Those resources may provide data extracted from databases or DAS tracks, or even results returned by local or remote bioinformatics analysis tools. This also implies that structured data can be edited via dedicated forms. Hence, this generic resource combines the structure of biological databases with the flexibility of collaborative Wikis. The source code and its documentation are freely available on the MediaWiki website: http://www.mediawiki.org/wiki/Extension:WikiOpener.

    Introductory-level Earth science courses provide the opportunity for science and non-science majors to expand discipline-specific content knowledge while enhancing skill sets applicable to all disciplines. The outcomes of the student work can then benefit the education and outreach efforts of an international organization - in this case, a wiki devoted exclusively to the geosciences, managed by the Society of Exploration Geophysicists (SEG). The course Environment Earth at Penn State Brandywine is a general education science course with the overarching course goal for students to understand, communicate examples, and make informed decisions relating to big ideas and fundamental concepts of Earth science. To help accomplish this goal, students carry out a semester-long digital engaged scholarship project that benefits the users of the SEG Wiki (http://wiki.seg.org/). To begin with developing the literacy of students and their ability to read, interpret, and evaluate sources of scientific news, the first assignment requires students to write an annotated bibliography on a specific topic that serves as the foundation for a new SEG Wiki article. Once students have collected and summarized information from reliable sources, students learn how writing for a wiki is different than writing a term paper and begin drafting their wiki page. Students peer review each other's work for content and clarity before publishing their work on the SEG wiki. Students respond positively to this project, reporting a better understanding of and respect towards the authors of online wiki pages, as well as an overall satisfaction of knowing their work will benefit others. Links to student-generated pages and instructional materials can be found at: http://sites.psu.edu/segwiki/.

    In times of RIS (radiology information system) and KIS (hospital information system) systems, patient-related data are at the radiologist's disposal at the push of a button. However, this is not the case for other important data. The increasing complexity of modern medicine demands that up-to-date information like protocols, SOPs (Standards of Practice), news and modifications are constantly accessible to all employees. This aspect of quality assurance becomes increasingly important in the context of certification. For such knowledge management purposes we have built a wiki in our department. Here we report our positive experiences with this technology.

  12. Search extension transforms Wiki into a relational system: a case for flavonoid metabolite database.

    Arita, Masanori; Suwa, Kazuhiro

    2008-09-17

    In computer science, database systems are based on the relational model founded by Edgar Codd in 1970. On the other hand, in the area of biology the word 'database' often refers to loosely formatted, very large text files. Although such bio-databases may describe conflicts or ambiguities (e.g. a protein pair do and do not interact, or unknown parameters) in a positive sense, the flexibility of the data format sacrifices a systematic query mechanism equivalent to the widely used SQL. To overcome this disadvantage, we propose embeddable string-search commands on a Wiki-based system and designed a half-formatted database. As proof of principle, a database of flavonoid with 6902 molecular structures from over 1687 plant species was implemented on MediaWiki, the background system of Wikipedia. Registered users can describe any information in an arbitrary format. Structured part is subject to text-string searches to realize relational operations. The system was written in PHP language as the extension of MediaWiki. All modifications are open-source and publicly available. This scheme benefits from both the free-formatted Wiki style and the concise and structured relational-database style. MediaWiki supports multi-user environments for document management, and the cost for database maintenance is alleviated.

    Full Text Available A web-based knowledge sharing system was experimentally developed on the LAN using the INTERSAT communication system, at Syowa Station during the wintering period of the 47th Japanese Antarctic Research Expedition (JARE47, 2005-2007. The system works on "wiki", which is a collaborative technology for organizing information on web sites. Wiki allows users to catch up on information produced by various activities at the station to date, linking and tracing among a large number of pages. A number of wiki systems have been developed under the GNU General Public License. JARE47 experimentally introduced a "PukiWiki" system in which all data are stored in hypertext format, and binary files can be attached to any pages. PukiWiki is able to extend its functions by using plug-ins, which allow users to modify the system. The wiki at Syowa Station was started on a small scale and expanded to permit storage of data entered by individual members, and to permit sharing of information up to date among all members, becoming a portal site for wintering members. During the complicated operations in summer season when many groups pursued the individual field activities, wiki played an important role for reconfirming and modifying procedures among members, as the key station around the Syowa area.

  15. VuWiki: An Ontology-Based Semantic Wiki for Vulnerability Assessments

    2014-05-01

    The concept of vulnerability, as well as its implementation in vulnerability assessments, is used in various disciplines and contexts ranging from disaster management and reduction to ecology, public health or climate change and adaptation, and a corresponding multitude of ideas about how to conceptualize and measure vulnerability exists. Three decades of research in vulnerability have generated a complex and growing body of knowledge that challenges newcomers, practitioners and even experienced researchers. To provide a structured representation of the knowledge field "vulnerability assessment", we have set up an ontology-based semantic wiki for reviewing and representing vulnerability assessments: VuWiki, www.vuwiki.org. Based on a survey of 55 vulnerability assessment studies, we first developed an ontology as an explicit reference system for describing vulnerability assessments. We developed the ontology in a theoretically controlled manner based on general systems theory and guided by principles for ontology development in the field of earth and environment (Raskin and Pan 2005). Four key questions form the first level "branches" or categories of the developed ontology: (1) Vulnerability of what? (2) Vulnerability to what? (3) What reference framework was used in the vulnerability assessment?, and (4) What methodological approach was used in the vulnerability assessment? These questions correspond to the basic, abstract structure of the knowledge domain of vulnerability assessments and have been deduced from theories and concepts of various disciplines. The ontology was then implemented in a semantic wiki which allows for the classification and annotation of vulnerability assessments. As a semantic wiki, VuWiki does not aim at "synthesizing" a holistic and overarching model of vulnerability. Instead, it provides both scientists and practitioners with a uniform ontology as a reference system and offers easy and structured access to the knowledge field of

    Wikis have the potential to promote best practices in health systems by sharing order sets with a broad community of stakeholders. However, little is known about the impact of using a wiki on clinicians' intention to use wiki-based order sets. The aims of this study were: (1) to describe the use of a wiki to create structured order sets for a single emergency department; (2) to evaluate whether the use of this wiki changed emergency physicians' future intention to use wiki-based order sets; and (3) to understand the impact of using the wiki on the behavioral determinants for using wiki-based order sets. This was a pre/post-intervention mixed-methods study conducted in one hospital in Lévis, Quebec. The intervention was comprised of receiving access to and being motivated by the department head to use a wiki for 6 months to create electronic order sets designed to be used in a computer physician order entry system. Before and after our intervention, we asked participants to complete a previously validated questionnaire based on the Theory of Planned Behavior. Our primary outcome was the intention to use wiki-based order sets in clinical practice. We also assessed participants' attitude, perceived behavioral control, and subjective norm to use wiki-based order sets. Paired pre- and post-Likert scores were compared using Wilcoxon signed-rank tests. The post-questionnaire also included open-ended questions concerning participants' comments about the wiki, which were then classified into themes using an existing taxonomy. Twenty-eight emergency physicians were enrolled in the study (response rate: 100%). Physicians' mean intention to use a wiki-based reminder was 5.42 (SD 1.04) before the intervention, and increased to 5.81 (SD 1.25) on a 7-point Likert scale (P =.03) after the intervention. Participants' attitude towards using a wiki-based order set also increased from 5.07 (SD 0.90) to 5.57 (SD 0.88) (P =.003). Perceived behavioral control and subjective norm did not

    Full Text Available As an emerging complex concept, GeoDesign requires an innovative theoretical basis, tools, supports and practices. For this reason, we propose a new concept, “WikiGIS”, designed to answer some dimensions of the GeoDesign process. WikiGIS focuses on the needs of GeoDesign, but we leave the door open for future improvement when tested in other areas that may have additional needs. WikiGIS is built on Web 2.0 technologies—and primarily on wiki—to manage the tracking of participants’ editing (i.e., managing the contributions history. It also offers GIS functions for geoprocessing and a design-based approach for sketching proposals. One of the main strengths of WikiGIS is its ability to manage the traceability of contributions with an easy and dynamical access, data quality and deltification. The core of this paper consists of presenting a conceptual framework for WikiGIS using UML diagrams. A user interface is presented later to show how our WikiGIS proposal works. This interface is simply a means to illustrate the concepts underlying WikiGIS.

    BACKGROUND, AIMS AND METHODS: Recent years have seen the introduction of web-based technologies such as the 'wiki', which is a webpage whose content can be edited in real time using a web browser. This article reviews the current state of knowledge about the use of wikis in education, and considers whether wiki technology has features that might prove useful in medical education. Advantages and challenges of the technology are discussed, and recommendations for use are provided. We believe that wiki technology offers a number of potential benefits for administrators, students and instructors, including the ability to share information online, to construct knowledge together, to facilitate collaboration and to enable social learning and peer feedback. We believe that with proper planning and instructional design, wiki technology can be usefully employed in medical education. We intend to continue to study the impact of wiki technology in our own programme, and we encourage others to evaluate the application of wiki technology in other areas of medical education.

    2015-01-01

    Background Wikis may give clinician communities the opportunity to build knowledge relevant to their practice. The only previous study reviewing a set of health-related wikis, without specification of purpose or audience, globally showed a poor reliability. Objective Our aim was to review medical wiki websites dedicated to clinical practices. Methods We used Google in ten languages, PubMed, Embase, Lilacs, and Web of Science to identify websites. The review included wiki sites, accessible and operating, having a topic relevant for clinical medicine, targeting physicians or medical students. Wikis were described according to their purposes, platform, management, information framework, contributions, content, and activity. Purposes were classified as “encyclopedic” or “non-encyclopedic”. The information framework quality was assessed based on the Health On the Net (HONcode) principles for collaborative websites, with additional criteria related to users’ transparency and editorial policy. From a sample of five articles per wikis, we assessed the readability using the Flesch test and compared articles according to the wikis’ main purpose. Annual editorial activities were estimated using the Google engine. Results Among 25 wikis included, 11 aimed at building an encyclopedia, five a textbook, three lessons, two oncology protocols, one a single article, and three at reporting clinical cases. Sixteen wikis were specialized with specific themes or disciplines. Fifteen wikis were using MediaWiki software as-is, three were hosted by online wiki farms, and seven were purpose-built. Except for one MediaWiki-based site, only purpose-built platforms managed detailed user disclosures. The owners were ten organizations, six individuals, four private companies, two universities, two scientific societies, and one unknown. Among 21 open communities, 10 required users’ credentials to give editing rights. The median information framework quality score was 6 out of 16

    Full Text Available Wikis are used in mathematics education in a variety of ways [3]. As with Wikipedia, mathematics related Wikis provide pages and links that describe many different branches of mathematics. Another common use is as a portal for distributing and collecting mathematics course materials [1]. This article describes the authors' use of course wikis for two different purposes in two undergraduate math courses. In Calculus-I, a wiki was utilized to share and present the outcome of an optimization problem that required small groups to collect information about student homes' attic insulation status and eventually to compute the optimal amount of new insulation to add that maximizes heating savings. The second wiki was for a small seminar-style course on Mathematical Mysteries where students collected and posted the results of their research relating to famous unsolved problems in mathematics. This wiki was also used as a platform for in-class presentations by the students and the instructors. In both cases, the bulk of the wiki contribution was by students.

    Full Text Available Semantic Wiki consentono, tramite un linguaggio comprensibile agli elaboratori e formalmente definito, l’annotazione semantica dei contenuti delle pagine Wiki e la rappresentazione esplicita delle relazioni di significato tra essi presenti. Essi offrono la possibilità di sfruttare sia i vantaggi delle tecnologie basate su ontologie sia i meccanismi collaborativi propri dei Wiki. L’articolo descrive un progetto, denominato Semantic WikiSUN, avviato per indagare le prospettive didattiche di tali sistemi. Esso è basato su un quadro teorico complesso che integra evidenze neurocognitive, teorie dell’apprendimento e modelli costruttivisti-sociali della conoscenza. Obiettivo del contributo è, sulla base della esperienza intrapresa, discutere potenzialità e criticità didattiche dei Semantic Wiki, estendendo talvolta la riflessione a considerazioni più generali sui processi di apprendimento mediati da tecnologie semantiche.

    Salganik, Matthew J.; Levy, Karen E. C.

    2015-01-01

    In the social sciences, there is a longstanding tension between data collection methods that facilitate quantification and those that are open to unanticipated information. Advances in technology now enable new, hybrid methods that combine some of the benefits of both approaches. Drawing inspiration from online information aggregation systems like Wikipedia and from traditional survey research, we propose a new class of research instruments called wiki surveys. Just as Wikipedia evolves over time based on contributions from participants, we envision an evolving survey driven by contributions from respondents. We develop three general principles that underlie wiki surveys: they should be greedy, collaborative, and adaptive. Building on these principles, we develop methods for data collection and data analysis for one type of wiki survey, a pairwise wiki survey. Using two proof-of-concept case studies involving our free and open-source website www.allourideas.org, we show that pairwise wiki surveys can yield insights that would be difficult to obtain with other methods.

    Simon Peter Rowberry

    2012-07-01

    Full Text Available Since the 'Against the Day 'Wiki launched in October 2006, the Pynchon Wiki collection has received over twenty thousand edits, making it one of the largest, dedicated literary reference Wikis. One can now view and add annotations to all seven of Pynchon’s novels – only 'Slow Learner 'and his non-fiction remain 'sans 'Wiki -, and a loose community of over four hundred contributors have done so. This paper will assess the importance of the 'Gravity’s Rainbow 'Wiki in transforming understanding and interpretation through asking four different questions: does the Wiki count as a disruptive force in the Pynchon interpretive industry, who contributes to the Wiki, what types of contribution they make, and how do they exploit the hypertextual features on offer through the MediaWiki package. I will suggest that the Pynchon Wiki does not fully depart from old media forms of interpretation and remains fragmented in both community, resembling a symphony of soloists, and potential connections. This is a version of Web 2.0 synthesizing both Darcy DiNucci’s original dystopian vision of fragmentation (DiNucci and Tim O’Reilly’s utopian idea of harnessing ‘collective intelligence’ (O’Reilly.

    Thanks to the broad availability of internet access and the development of browser-based web applications known as 'wikis' (Hawaiian word for 'quick, fast'), it became possible for internet users to participate on big collaborative encyclopedic projects. The best example is Wikipedia, an online encyclopedia based on MediaWiki that receives contributions from internet users around the world. In this context, the word 'wiki' usually refers to the wiki software itself, and/or the collection of hypertext documents managed by it. Wiki software allows creating, editing and managing online-shared documents, which become available immediately after they are created/edited. With such capabilities, wikis can also be used within organizations as tools to allow its employees to collaborate in the construction of a common knowledge base containing information relevant to the organization. In such context, the wiki becomes a tool for knowledge management. This article describes the implementation of the WikiIEN, which is based on MediaWiki, as a tool for knowledge management at the IEN - Instituto de Engenharia Nuclear. This tool aims to improve the sharing of information among institute researchers, thorough a dynamic common knowledge base that can be on-line updated. In the article are presented the logical and computational structure of the wiki created for deposit of the knowledge generated at the IEN. (author)

  15. Refactoring affordances in corporate wikis: a case for the use of mind maps

    Puente, Gorka; Díaz, Oscar; Azanza, Maider

    2015-11-01

    The organisation of corporate wikis tends to deteriorate as time goes by. Rearranging categories, structuring articles and even moving sections among articles are cumbersome tasks in current wiki engines. This discourages the layman. But, it is the layman who writes the articles, knows the wiki content and detects refactoring opportunities. Our goal is to improve the refactoring affordances of current wiki engines by providing an alternative front-end tuned to refactoring. This is achieved by (1) surfacing the structure of the wiki corpus as a mind map, and (2) conducting refactoring as mind map reshaping. To this end, we introduce WikiWhirl, a domain-specific language for wiki refactoring. WikiWhirl is supported as an extension of FreeMind, a popular mind mapping tool. In this way, refactoring operations are intuitively conducted as actions upon mind map nodes. In a refactoring session a user imports the wiki structure as a FreeMind map; next, conducts the refactoring operations on the map, and finally, the effects are saved in the wiki database. The operational semantics of the WikiWhirl operations follow refactoring good practices (e.g., authorship preservation). Results from a controlled experiment suggest that WikiWhirl outperforms MediaWiki in three main affordance enablers: understandability, productivity and fulfillment of refactoring good practices.

    Full Text Available This study reports on the comparison of the students’ achievement and their attitudes towards the use of paper-pen peer-correction and wiki-based peer-correction within English language lessons and CLIL Social Science lessons at the higher secondary school in Prague. Questionnaires and semi-structured interviews were utilized to gather information. The data suggests that students made considerable use of wikis and showed higher degrees of motivation in wiki-based peer-correction during English language lessons than in CLIL Social Science lessons. In both cases wikis not only contributed to developing students’ writing skills, but also helped students recognize the importance of collaboration.

    Wiki systems form a subclass of the more general Open Collaborative Authoring Systems, where content is created and maintained by a user community. The ability of anyone to edit the content is, at the same time, their strength and their weakness. Anyone can write documents that improve the value...... of the wiki-system, but at the same time, anyone can also introduce errors into these documents, by accident or on purpose. A security model for wiki-style authoring systems has previously been proposed. This model is based on both static and dynamic document access controls that enforce a simple integrity......, but this is true for all soft security systems. We show that the system parameters can be tuned so that the amount of work required by malicious and colluding users to reach this level is well beyond most attackers' capabilities....

    The social web stimulates learning through collaboration. However, information in the social web is often associated with information about its author. Based on previous evidence that ingroup information is preferred to outgroup information, the current research investigates whether group memberships of wiki authors affect learning. In an experimental study, we manipulated the group memberships (ingroup vs. outgroup) of wiki authors by using nicknames. The designated group memberships (being fans of a soccer team or not) were completely irrelevant for the domain of the wiki (the medical disorder fibromyalgia). Nevertheless, wiki information from the ingroup led to more integration of information into prior knowledge as well as more increase of factual knowledge than information from the outgroup. The results demonstrate that individuals apply social selection strategies when considering information from wikis, which may foster, but also hinder, learning and collaboration. Practical implications for collaborative learning in the social web are discussed.

    2015-06-01

    The use of wiki technology fits well in courses that encourage constructive knowledge building and social learning by a community of learners. Pedagogically, wikis have attracted interest in higher education environments because they facilitate the collaborative processes required for developing student group assignments. This article describes a pilot project to assess the implementation of wikis in two online small- and mid-sized elective courses comprising nursing students in third- or fourth-year undergraduate levels within interdisciplinary health sciences courses. The need exists to further develop the pedagogical use of wiki environments before they can be expected to support collaboration among undergraduate nursing students. Adapting wiki implementation to suitable well-matched courses will make adaptation of wikis into nursing curricula more effective and may increase the chances that nursing students will hone the collaborative abilities that are essential in their future professional roles in communities of practice.

    A central challenge organizations face is how to build, store, and maintain knowledge over time. Enterprise wikis are community-based knowledge systems situated in an organizational context. These systems have the potential to play an important role in managing knowledge within organizations......, but the motivating factors that drive individuals to contribute their knowledge to these systems is not very well understood. We theorize that enterprise wiki initiatives require two separate and distinct types of knowledge-sharing behaviors to succeed: knowledge creation (KC) and knowledge integration (KI).

  4. WikiHyperGlossary (WHG): an information literacy technology for chemistry documents.

    Science.gov (United States)

    Bauer, Michael A; Berleant, Daniel; Cornell, Andrew P; Belford, Robert E

    2015-01-01

    The WikiHyperGlossary is an information literacy technology that was created to enhance reading comprehension of documents by connecting them to socially generated multimedia definitions as well as semantically relevant data. The WikiHyperGlossary enhances reading comprehension by using the lexicon of a discipline to generate dynamic links in a document to external resources that can provide implicit information the document did not explicitly provide. Currently, the most common method to acquire additional information when reading a document is to access a search engine and browse the web. This may lead to skimming of multiple documents with the novice actually never returning to the original document of interest. The WikiHyperGlossary automatically brings information to the user within the current document they are reading, enhancing the potential for deeper document understanding. The WikiHyperGlossary allows users to submit a web URL or text to be processed against a chosen lexicon, returning the document with tagged terms. The selection of a tagged term results in the appearance of the WikiHyperGlossary Portlet containing a definition, and depending on the type of word, tabs to additional information and resources. Current types of content include multimedia enhanced definitions, ChemSpider query results, 3D molecular structures, and 2D editable structures connected to ChemSpider queries. Existing glossaries can be bulk uploaded, locked for editing and associated with multiple social generated definitions. The WikiHyperGlossary leverages both social and semantic web technologies to bring relevant information to a document. This can not only aid reading comprehension, but increases the users' ability to obtain additional information within the document. We have demonstrated a molecular editor enabled knowledge framework that can result in a semantic web inductive reasoning process, and integration of the WikiHyperGlossary into other software technologies, like

  10. Education in health research methodology: use of a wiki for knowledge translation.

    Directory of Open Access Journals (Sweden)

    Michele P Hamm

    Full Text Available INTRODUCTION: A research-practice gap exists between what is known about conducting methodologically rigorous randomized controlled trials (RCTs and what is done. Evidence consistently shows that pediatric RCTs are susceptible to high risk of bias; therefore novel methods of influencing the design and conduct of trials are required. The objective of this study was to develop and pilot test a wiki designed to educate pediatric trialists and trainees in the principles involved in minimizing risk of bias in RCTs. The focus was on preliminary usability testing of the wiki. METHODS: The wiki was developed through adaptation of existing knowledge translation strategies and through tailoring the site to the identified needs of the end-users. The wiki was evaluated for usability and user preferences regarding the content and formatting. Semi-structured interviews were conducted with 15 trialists and systematic reviewers, representing varying levels of experience with risk of bias or the conduct of trials. Data were analyzed using content analysis. RESULTS: Participants found the wiki to be well organized, easy to use, and straightforward to navigate. Suggestions for improvement tended to focus on clarification of the text or on esthetics, rather than on the content or format. Participants liked the additional features of the site that were supplementary to the text, such as the interactive examples, and the components that focused on practical applications, adding relevance to the theory presented. While the site could be used by both trialists and systematic reviewers, the lack of a clearly defined target audience caused some confusion among participants. CONCLUSIONS: Participants were supportive of using a wiki as a novel educational tool. The results of this pilot test will be used to refine the risk of bias wiki, which holds promise as a knowledge translation intervention for education in medical research methodology.

  11. Students’ engagement with a collaborative wiki tool predicts enhanced written exam performance

    Directory of Open Access Journals (Sweden)

    2014-08-01

    Full Text Available We introduced voluntary wiki-based exercises to a long-running cognitive psychology course, part of the core curriculum for an undergraduate degree in psychology. Over 2 yearly cohorts, students who used the wiki more also scored higher on the final written exam. Using regression analysis, it is possible to account for students’ tendency to score well on other psychology exams, thus statistically removing some obvious candidate third factors, such as general talent or enthusiasm for psychology, which might drive this correlation. Such an analysis shows that both high- and low-grading students who used the wiki got higher scores on the final exam, with engaged wiki users scoring an average of an extra 5 percentage points. We offer an interpretation of the mechanisms of action in terms of the psychological literature on learning and memory.

    Full Text Available In computer-supported collaborative learning (CSCL environments, there are many researches done on collaborative learning activities; however, in game-based learning environments, more research and literature on collaborative learning activities are required. Actually, both game-based learning environments and wikis enable us to use new chances for learning, especially in collaborative learning activities. Therefore, in this paper, related literature on wikis and how game & instructional designers can leverage from wikis in game-based learning settings for enhancing students’ collaborative learning activities are examined. Based on the reviewed literature, two main suggestions are given in this paper with their underlying reasons. First, using wikis as a support tool for enhancing collaboration in digital game-based learning (DGBL environments, and second using wikis as an assessment tool in DGBL are suggested.

    Full Text Available Educational technology is a dynamic major which is ever developing. In the past, educational technology was one dimensional, but nowadays it has become multi-dimensional, flexible and learner-centered. A revolution has happened in teaching methods from the perspective of web. Novel technologies in web and new role of users’ have led to the appearance of application programs on the basis of collaborative and social intelligence. Users have active participation, exploit their own beliefs, make the target concept, edit it and participate there. The most important feature of this kind of media is users’ ability to participate in its content production. Users can exploit wikis in the process of educational technology. A wiki is a social medium which enables users to produce and edit constantly in an HTML environment. The aim of this article is to introduce wikis as educational and training tools. The degree to which these obstacles affect ICT users and institutes can support decision-making on how to equip them is discussed.

    2016-01-01

    Although wikis appear to have been reported as effective tools for educators, uncertainty exists as to their effectiveness in achieving student learning outcomes. The aim of this integrative review was to examine the current evidence on the impact of wikis on student learning in courses requiring collaborative or co-developed assignments or activities. The authors searched several electronic databases for relevant articles and used R. Whittemore and K. Knafl's (2005) integrative review method to analyze and synthesize the evidence. Twenty-five articles met the selection criteria for this review, and four major themes for wiki use were identified: (a) writing skills, (b) collaboration, (c) knowledge acquisition, and (d) centralized repository. Although wikis have been found useful in improving student learning outcomes and hold great potential as an instructional strategy to aid students in learning various skills and gaining new knowledge, more research is needed on their effectiveness, especially in the area of nursing education.

  18. Distributed scaffolding: Wiki collaboration among Latino high school chemistry students

    Science.gov (United States)

    O'Sullivan, Edwin Duncan, Jr.

    The primary purpose of this study was to evaluate if wiki collaboration among Latino high school chemistry students can help reduce the science achievement gap between Latino and White students. The study was a quasi-experimental pre/post control group mixed-methods design. It used three intact sections of a high school chemistry course. The first research question asked if there is a difference in academic achievement between a treatment and control group on selected concepts from the topics of bonding, physical changes, and chemical changes, when Latino high school chemistry students collaborate on a quasi-natural wiki project. Overall results for all three activities (Bonding, Physical Changes, and Chemical Changes) indicated no significant difference between the wiki and control group. However, students performing the chemical changes activity did significantly better than their respective control group. Furthermore, there was a significant association, with large effect size, between group membership and ability to overcome the misconception that aqueous ionic reactants in precipitation reactions exist as molecular pairs of ions. Qualitative analysis of classroom and computer lab dialogue, discussion board communication, student focus groups, teacher interviews, and wiki content attributes the better performance of the chemical changes wiki group to favorable differences in intersubjectivity and calibrated assistance, as well as learning about submicroscopic representations of precipitation reactions in multiple contexts. Furthermore, the nonsignificant result overall points to an aversion to peer editing as a possible cause. Drawing considerably on Vygotsky and Piaget, the results are discussed within the context of how distributed scaffolding facilitated medium levels of cognitive conflict. The second research question asked what the characteristics of distributed metacognitive scaffolding are when Latino high school chemistry students collaborate on a quasi

    WikiPathways (wikipathways.org) captures the collective knowledge represented in biological pathways. By providing a database in a curated, machine readable way, omics data analysis and visualization is enabled. WikiPathways and other pathway databases are used to analyze experimental data by research groups in many fields. Due to the open and collaborative nature of the WikiPathways platform, our content keeps growing and is getting more accurate, making WikiPathways a reliable and rich pathway database. Previously, however, the focus was primarily on genes and proteins, leaving many metabolites with only limited annotation. Recent curation efforts focused on improving the annotation of metabolism and metabolic pathways by associating unmapped metabolites with database identifiers and providing more detailed interaction knowledge. Here, we report the outcomes of the continued growth and curation efforts, such as a doubling of the number of annotated metabolite nodes in WikiPathways. Furthermore, we introduce an OpenAPI documentation of our web services and the FAIR (Findable, Accessible, Interoperable and Reusable) annotation of resources to increase the interoperability of the knowledge encoded in these pathways and experimental omics data. New search options, monthly downloads, more links to metabolite databases, and new portals make pathway knowledge more effortlessly accessible to individual researchers and research communities. © The Author(s) 2017.

    2018-03-01

    Full Text Available The WikiLeaks’ founder represents not only a challenge to freedom of information, but also to International Law related to the diplomatic asylum. Julian Assange has been living in the Ecuadorian embassy in London for five years. In the last weeks, news surfaced that Sweden has ceased to request his extradition, the fact that caused much of the case under study. Assange’s situation seems to be diametrically different from Edward Snowden’s; however, both are labeled as "refugees for political reasons". While Assange looks forward to an improvement in his situation in the Ecuadorian embassy in London, Snowden still lives in Russia. Is the diplomatic asylum a usual practice? How to understand the diplomatic asylum in Latin America? What about England? In this paper, the analysis will assume that the concept of asylum is not recognized as a universal practice of International Law. However, in Latin America, it seems to be a usual practice since the judgment of the International Court of Justice on Haya de la Torre’s case.

    2016-11-01

    To describe the creation and evaluate the usage of the first medical wiki linked to dedicated mobile applications. With the support of multiple current and past contributors, we developed an emergency medicine wiki linked to offline mobile applications (WikEM) in 2009. First deployment was at the Harbor-UCLA Medical Center emergency medicine residency program, with the wiki later opened to public use. To evaluate the project, we performed a post hoc analysis of system use and surveyed 8 years of current and past residents. Outcomes included website and application analytics, as well as survey analysis by composite response categories. Over the 6-year period of this project, the wiki grew to over 7250 pages and 45 500 edits. The website receives more than 85 000 user sessions per month, with over 150 million page views to date. There have been over 200 000 installs of the mobile applications, progressing to produce over 5000 mobile sessions daily. Of potential survey respondents, 87.7% (107) completed the Internet-based survey. Among those who contributed to the wiki, 74.6% reported that it benefited their understanding of core emergency medicine content. Of program graduates, the vast majority reported use of the wiki as a resource after residency (93.8%) along with improvement in clinical efficiency (89.7%). Residents reported higher use and a more favorable opinion of wiki usefulness compared to graduates (P mobile applications is beneficial for resident education and useful in post-residency clinical practice. © The Author 2016.

    2015-01-01

    Today researchers can choose from many bioinformatics protocols for all types of life sciences research, computational environments and coding languages. Although the majority of these are open source, few of them possess all virtues to maximize reuse and promote reproducible science. Wikipedia has proven a great tool to disseminate information and enhance collaboration between users with varying expertise and background to author qualitative content via crowdsourcing. However, it remains an open question whether the wiki paradigm can be applied to bioinformatics protocols. We piloted PyPedia, a wiki where each article is both implementation and documentation of a bioinformatics computational protocol in the python language. Hyperlinks within the wiki can be used to compose complex workflows and induce reuse. A RESTful API enables code execution outside the wiki. Initial content of PyPedia contains articles for population statistics, bioinformatics format conversions and genotype imputation. Use of the easy to learn wiki syntax effectively lowers the barriers to bring expert programmers and less computer savvy researchers on the same page. PyPedia demonstrates how wiki can provide a collaborative development, sharing and even execution environment for biologists and bioinformaticians that complement existing resources, useful for local and multi-center research teams. PyPedia is available online at: http://www.pypedia.com. The source code and installation instructions are available at: https://github.com/kantale/PyPedia_server. The PyPedia python library is available at: https://github.com/kantale/pypedia. PyPedia is open-source, available under the BSD 2-Clause License.

  3. The pathology informatics curriculum wiki: Harnessing the power of user-generated content.

    2010-07-13

    The need for informatics training as part of pathology training has never been so critical, but pathology informatics is a wide and complex field and very few programs currently have the resources to provide comprehensive educational pathology informatics experiences to their residents. In this article, we present the "pathology informatics curriculum wiki", an open, on-line wiki that indexes the pathology informatics content in a larger public wiki, Wikipedia, (and other online content) and organizes it into educational modules based on the 2003 standard curriculum approved by the Association for Pathology Informatics (API). In addition to implementing the curriculum wiki at http://pathinformatics.wikispaces.com, we have evaluated pathology informatics content in Wikipedia. Of the 199 non-duplicate terms in the API curriculum, 90% have at least one associated Wikipedia article. Furthermore, evaluation of articles on a five-point Likert scale showed high scores for comprehensiveness (4.05), quality (4.08), currency (4.18), and utility for the beginner (3.85) and advanced (3.93) learners. These results are compelling and support the thesis that Wikipedia articles can be used as the foundation for a basic curriculum in pathology informatics. The pathology informatics community now has the infrastructure needed to collaboratively and openly create, maintain and distribute the pathology informatics content worldwide (Wikipedia) and also the environment (the curriculum wiki) to draw upon its own resources to index and organize this content as a sustainable basic pathology informatics educational resource. The remaining challenges are numerous, but largest by far will be to convince the pathologists to take the time and effort required to build pathology informatics content in Wikipedia and to index and organize this content for education in the curriculum wiki.

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

    2012-12-01

    Full Text Available The dominant form of teaching in higher education remains the lecture,even though evidence suggests that it alone is inadequate to facilitate the development ofthe higher order thinking skills required in clinical practice. The use of wikis may have a roleto play in facilitating collaborative learning practices that are important for professionaldevelopment. This descriptive survey evaluated the use of a wiki for a collaborative learningactivity within small groups of undergraduate physiotherapy students in a South Africanuniversity. Students participated in a wiki-based assignment and were then surveyedusing open- and closed-ended questions to determine their perceptions and experiences of the process. The results indicate thatalthough a wiki can be used to develop relevant content, there were significant challenges in its implementation. These included apoor understanding by students of how to work effectively in groups, a lack of physical and epistemological access to the internet,and the need for adequate preparation and support. Some features of the wiki were found to have an impact on the quality ofthe work produced, including the use of Discussion pages, peer review, and the public nature of the wiki. The conclusion is thatwikis may have a role to play in collaborative groupwork, but that that students need to be adequately prepared and supportedthroughout the process.

  8. SOIL Geo-Wiki: A tool for improving soil information

    Crowdsourcing is increasingly being used as a way of collecting data for scientific research, e.g. species identification, classification of galaxies and unravelling of protein structures. The WorldSoilProfiles.org database at ISRIC is a global collection of soil profiles, which have been 'crowdsourced' from experts. This system, however, requires contributors to have a priori knowledge about soils. Yet many soil parameters can be observed in the field without specific knowledge or equipment such as stone content, soil depth or color. By crowdsourcing this information over thousands of locations, the uncertainty in current soil datasets could be radically reduced, particularly in areas currently without information or where multiple interpretations are possible from different existing soil maps. Improved information on soils could benefit many research fields and applications. Better soil data could enhance assessments of soil ecosystem services (e.g. soil carbon storage) and facilitate improved process-based ecosystem modeling from local to global scales. Geo-Wiki is a crowdsourcing tool that was developed at IIASA for land cover validation using satellite imagery. Several branches are now available focused on specific aspects of land cover validation, e.g. validating cropland extent or urbanized areas. Geo-Wiki Pictures is a smart phone application for collecting land cover related information on the ground. The extension of Geo-Wiki to a mobile environment provides a tool for experts in land cover validation but is also a way of reaching the general public in the validation of land cover. Here we propose a Soil Geo-Wiki tool that builds on the existing functionality of the Geo-Wiki application, which will be largely designed for the collection and sharing of soil information. Two distinct applications are envisaged: an expert-oriented application mainly for scientific purposes, which will use soil science related language (e.g. WRB or any other global reference

    Full Text Available This paper aims at proposing a technique for students learning English as a foreign language when they collaboratively write an argumentative essay in a wiki environment. A wiki environment and collaborative work play an important role within the academic writing task. Nevertheless, an appropriate and systematic work assignment is required in order to make use of both. In this paper the proposed technique when writing a collaborative essay mainly attempts to provide the most effective way to enhance equal participation among group members by taking as a base computer mediated collaboration. Within this context, the students’ role is clearly defined and individual and collaborative tasks are explained.

    2016-03-01

    Full Text Available This paper describes the collaborative learning task carried out in the framework of a Strength of Materials course in an undergraduate degree program in Industrial Engineering using a wiki platform as a support tool. Stages of the teaching/learning process are described. These are: organization of the wiki to host the work of student groups, creation of working groups and assignation of projects, delivery of guidance material and model, editing the project and publishing pages on the wiki, assessments performed using rubrics, and the results obtained. The wiki platform provides interesting statistics for evaluating cooperation between students and time variation of students’ effort. The final quality of the projects is very high because a midterm evaluation in the form of a “peer review rubric” is carried out. Then, students improve their projects. The paper concludes by gathering the opinions made by students; the benefits provided by this teaching experience are then analyzed.

  17. ArrayWiki: an enabling technology for sharing public microarray data repositories and meta-analyses

    Science.gov (United States)

    Stokes, Todd H; Torrance, JT; Li, Henry; Wang, May D

    2008-01-01

    Background A survey of microarray databases reveals that most of the repository contents and data models are heterogeneous (i.e., data obtained from different chip manufacturers), and that the repositories provide only basic biological keywords linking to PubMed. As a result, it is difficult to find datasets using research context or analysis parameters information beyond a few keywords. For example, to reduce the "curse-of-dimension" problem in microarray analysis, the number of samples is often increased by merging array data from different datasets. Knowing chip data parameters such as pre-processing steps (e.g., normalization, artefact removal, etc), and knowing any previous biological validation of the dataset is essential due to the heterogeneity of the data. However, most of the microarray repositories do not have meta-data information in the first place, and do not have a a mechanism to add or insert this information. Thus, there is a critical need to create "intelligent" microarray repositories that (1) enable update of meta-data with the raw array data, and (2) provide standardized archiving protocols to minimize bias from the raw data sources. Results To address the problems discussed, we have developed a community maintained system called ArrayWiki that unites disparate meta-data of microarray meta-experiments from multiple primary sources with four key features. First, ArrayWiki provides a user-friendly knowledge management interface in addition to a programmable interface using standards developed by Wikipedia. Second, ArrayWiki includes automated quality control processes (caCORRECT) and novel visualization methods (BioPNG, Gel Plots), which provide extra information about data quality unavailable in other microarray repositories. Third, it provides a user-curation capability through the familiar Wiki interface. Fourth, ArrayWiki provides users with simple text-based searches across all experiment meta-data, and exposes data to search engine crawlers

    Full Text Available Aim/Purpose: To investigate the effectiveness of incorporating wiki technology in an under-graduate biostatistics course for improving university students’ collaborative learning, approaches to learning, and course performance. Methodology: During a three year longitudinal study, twenty-one and twenty-four undergraduate students were recruited by convenience sampling and assigned to a wiki group (2014-2015 and a control group (2013-2014 and 2015-2016, respectively. The students in the wiki group attended face-to-face lectures and used a wiki (PBworks weekly for online- group discussion, and the students in the control group had no access to the wiki and interacted face-to-face only. The students’ collaborative learning, approaches to learning, and course performance were evaluated using the Group Process Questionnaire (GPQ, Revised Study Process Questionnaire (R-SPQ-2F and course results, respectively, after testing. Findings: Multivariate analysis of variance results revealed that the R-SPQ-2F surface approach score, surface motive and strategy subscores were lower in the wiki group than in the control group (p < 0.05. The GPQ individual accountability and equal opportunity scores (components of collaboration were higher in the wiki group than in the control group (p < 0.001. No significant between-groups differences were found in any of the other outcome variables (i.e., overall course result, R-SPQ-2F deep approach score and subscores, GPQ positive interdependence score, social skills score, and composite score. Looking at the Wiki Questionnaire results, the subscale and composite scores we obtained were 31.5% to 37.7% lower than the norm. The wiki was used at a frequency of about 0.7 times per week per student. Recommendations for Practitioners: Using wiki technology in conjunction with the traditional face-to-face teaching method in a biostatistics course can enhance some aspects of undergraduate students’ collaborative learning

    Full Text Available Scope of online learning in higher education now more widely assumed to be a repository of teaching materials for both teachers and students. Nevertheless there are still many things that can still be developed and studied with an experimental model for online learning can be more participatory in the learning context given that the scope of the college is more directed to andragogik. One innovation that leads to this is to make the application of model-based learning wiki adopting crowdsourcing. This paper explores theoretical study attempted as a first step in the research development of wiki-based online learning model. The results of this study should be the basis for experiments to be conducted in order to adapt contextually in real state.

    Wikis are knowledge translation tools that could help health professionals implement best practices in acute care. Little is known about the factors influencing professionals' use of wikis. To identify and compare the beliefs of emergency physicians (EPs) and allied health professionals (AHPs) about using a wiki-based reminder that promotes evidence-based care for traumatic brain injuries. Drawing on the theory of planned behavior, we conducted semistructured interviews to elicit EPs' and AHPs' beliefs about using a wiki-based reminder. Previous studies suggested a sample of 25 EPs and 25 AHPs. We purposefully selected participants from three trauma centers in Quebec, Canada, to obtain a representative sample. Using univariate analyses, we assessed whether our participants' gender, age, and level of experience were similar to those of all eligible individuals. Participants viewed a video showing a clinician using a wiki-based reminder, and we interviewed participants about their behavioral, control, and normative beliefs-that is, what they saw as advantages, disadvantages, barriers, and facilitators to their use of a reminder, and how they felt important referents would perceive their use of a reminder. Two reviewers independently analyzed the content of the interview transcripts. We considered the 75% most frequently mentioned beliefs as salient. We retained some less frequently mentioned beliefs as well. Of 66 eligible EPs and 444 eligible AHPs, we invited 55 EPs and 39 AHPs to participate, and 25 EPs and 25 AHPs (15 nurses, 7 respiratory therapists, and 3 pharmacists) accepted. Participating AHPs had more experience than eligible AHPs (mean 14 vs 11 years; P = .04). We noted no other significant differences. Among EPs, the most frequently reported advantage of using a wiki-based reminder was that it refreshes the memory (n = 14); among AHPs, it was that it provides rapid access to protocols (n = 16). Only 2 EPs mentioned a disadvantage (the wiki added stress

    Open biological data are distributed over many resources making them challenging to integrate, to update and to disseminate quickly. Wikidata is a growing, open community database which can serve this purpose and also provides tight integration with Wikipedia. In order to improve the state of biological data, facilitate data management and dissemination, we imported all human and mouse genes, and all human and mouse proteins into Wikidata. In total, 59,721 human genes and 73,355 mouse genes have been imported from NCBI and 27,306 human proteins and 16,728 mouse proteins have been imported from the Swissprot subset of UniProt. As Wikidata is open and can be edited by anybody, our corpus of imported data serves as the starting point for integration of further data by scientists, the Wikidata community and citizen scientists alike. The first use case for these data is to populate Wikipedia Gene Wiki infoboxes directly from Wikidata with the data integrated above. This enables immediate updates of the Gene Wiki infoboxes as soon as the data in Wikidata are modified. Although Gene Wiki pages are currently only on the English language version of Wikipedia, the multilingual nature of Wikidata allows for usage of the data we imported in all 280 different language Wikipedias. Apart from the Gene Wiki infobox use case, a SPARQL endpoint and exporting functionality to several standard formats (e.g. JSON, XML) enable use of the data by scientists. In summary, we created a fully open and extensible data resource for human and mouse molecular biology and biochemistry data. This resource enriches all the Wikipedias with structured information and serves as a new linking hub for the biological semantic web. Database URL: https://www.wikidata.org/. © The Author(s) 2016.

    Hundreds of biological and biomedical ontologies have been developed to support data standardization, integration and analysis. Although ontologies are typically developed for community usage, community efforts in ontology development are limited. To support ontology visualization, distribution, and community-based annotation and development, we have developed Ontokiwi, an ontology extension to the MediaWiki software. Ontokiwi displays hierarchical classes and ontological axioms. Ontology classes and axioms can be edited and added using Ontokiwi form or MediaWiki source editor. Ontokiwi also inherits MediaWiki features such as Wikitext editing and version control. Based on the Ontokiwi/MediaWiki software package, we have developed Ontobedia, which targets to support community-based development and annotations of biological and biomedical ontologies. As demonstrations, we have loaded the Ontology of Adverse Events (OAE) and the Cell Line Ontology (CLO) into Ontobedia. Our studies showed that Ontobedia was able to achieve expected Ontokiwi features. PMID:27570653

    Full Text Available Los entornos digitales cada vez son más comunes en la enseñanza de lenguas extranjeras, además de jugar un papel muy importante como organizadores de tareas, proveedores de input y como gestores de recursos para la enseñanza de idiomas. Permiten, asimismo, a los profesores organizar la interacción de los estudiantes y, al mismo tiempo, proporcionar un magnífico entorno para presentar distintos géneros informativos. Las wikis son hoy en día una de las redes sociales que cada vez se utilizan más para dar apoyo al aprendizaje cooperativo y para fomentar el aprendizaje autónomo. Están estrechamente relacionadas con las metodologías docentes que se basan en el desarrollo de un proyecto o en la resolución de problemas, prácticas docentes éstas en las que tanto alumnos como profesores contribuyen a la construcción del conocimiento y comparten experiencias. Las wikis también han contribuido a crear las llamadas "comunidades de práctica", a las que pueden acudir los estudiantes en contextos de autoaprendizaje o en aquellas situaciones donde se carece del apoyo de un tutor o profesor para encontrar apoyo y consejo. Añadido a esto, la proliferación de herramientas que fomentan la comunicación mediatizada por ordenador han multiplicado los métodos docentes que se aplican en el aula y fuera de ella y han tenido una influencia muy significativa en el surgimiento de un nuevo perfil de estudiante; es decir, aquél que está plenamente acostumbrado a utilizar estas herramientas para relacionarse socialmente con otras personas aunque no sea con fines educativos. Por último, mediante el uso de las wikis se ha desarrollado el concepto de "enseñanza entre pares" y "tutorización entre pares", especialmente en contextos de creación de textos escritos mediante la cooperación colectiva. Este hecho ha contribuido, asimismo, a que el estudiante tenga mayor conciencia de los procesos implícitos en la construcción y edición textual. Este cap

  10. The use of virtual microscopy and a wiki in pathology education: Tracking student use, involvement, and response.

    Leifer, Zev

    2015-01-01

    The pathology laboratory course at the New York College of Podiatric Medicine involves the use of Virtual Microscopy. The students can scan the whole slide, section by section, and zoom in or out. Using the advantages of digital pathology, the students can, in addition, access the slide collections from other medical schools and put up normal histology (control) slides side-by-side with the pathology. They can cut and paste and preserve the region of interest that they find. They can edit and annotate their slides. A wiki was created (http://pathlab2014.wikifoundry.com)for the Class of 2014. The students saved, edited and uploaded their slides. In the wiki format, other students could comment, further edit, and even delete the slides. The students studied Basic Mechanisms and System Pathology. During this time, they saved, edited, shared, and uploaded their slides to the wiki. These were available in one full presentation and were also grouped into 16 albums. They were available to all. Student access was followed by Google analytics. At the end of the course, a questionnaire was distributed, assessing their impression of the wiki format and soliciting strengths and weaknesses. The use of a wiki has a number of important advantages in pathology education. It trains the students in the more sophisticated skills that they will use as professional pathologists or as clinicians: (1) Telepathology-it enables them to share slides and discuss observations. (2) Archiving and retrieval - It models the challenge faced by hospitals, diagnostic labs and physicians in maintaining a collection of slides in a form that is easily accessible. (3) Image analysis-familiarity with the wiki format allows them to jump easily to capturing and storing images found in the literature or in a pathologist's report. Experience with the use of a wiki in pathology education has been quite satisfactory from both the faculty and the student's point of view.

  11. Wiki management a revolutionary new model for a rapidly changing and collaborative world

    CERN Document Server

    2013-01-01

    We now live in a "wiki" world where mass collaboration is not only possible-it's often the best solution. Conventional management thought assumes that command-and-control is the most effective way to organize the efforts of large numbers of people, but rapid change and increasing complexity have rendered that model obsolete. As a result, most managers today lack the skills and knowledge needed to succeed in an age when networks are proving smarter and faster than hierarchies. Designing organizations for mass collaboration demands a new and very different model-wiki management.

  12. Wikis, blogs and podcasts: a new generation of Web-based tools for virtual collaborative clinical practice and education

    Full Text Available Abstract Background We have witnessed a rapid increase in the use of Web-based 'collaborationware' in recent years. These Web 2.0 applications, particularly wikis, blogs and podcasts, have been increasingly adopted by many online health-related professional and educational services. Because of their ease of use and rapidity of deployment, they offer the opportunity for powerful information sharing and ease of collaboration. Wikis are Web sites that can be edited by anyone who has access to them. The word 'blog' is a contraction of 'Web Log' – an online Web journal that can offer a resource rich multimedia environment. Podcasts are repositories of audio and video materials that can be "pushed" to subscribers, even without user intervention. These audio and video files can be downloaded to portable media players that can be taken anywhere, providing the potential for "anytime, anywhere" learning experiences (mobile learning. Discussion Wikis, blogs and podcasts are all relatively easy to use, which partly accounts for their proliferation. The fact that there are many free and Open Source versions of these tools may also be responsible for their explosive growth. Thus it would be relatively easy to implement any or all within a Health Professions' Educational Environment. Paradoxically, some of their disadvantages also relate to their openness and ease of use. With virtually anybody able to alter, edit or otherwise contribute to the collaborative Web pages, it can be problematic to gauge the reliability and accuracy of such resources. While arguably, the very process of collaboration leads to a Darwinian type 'survival of the fittest' content within a Web page, the veracity of these resources can be assured through careful monitoring, moderation, and operation of the collaborationware in a closed and secure digital environment. Empirical research is still needed to build our pedagogic evidence base about the different aspects of these tools in

    The diversity of online resources storing biological data in different formats provides a challenge for bioinformaticians to integrate and analyse their biological data. The semantic web provides a standard to facilitate knowledge integration using statements built as triples describing a relation between two objects. WikiPathways, an online collaborative pathway resource, is now available in the semantic web through a SPARQL endpoint at http://sparql.wikipathways.org. Having biological pathways in the semantic web allows rapid integration with data from other resources that contain information about elements present in pathways using SPARQL queries. In order to convert WikiPathways content into meaningful triples we developed two new vocabularies that capture the graphical representation and the pathway logic, respectively. Each gene, protein, and metabolite in a given pathway is defined with a standard set of identifiers to support linking to several other biological resources in the semantic web. WikiPathways triples were loaded into the Open PHACTS discovery platform and are available through its Web API (https://dev.openphacts.org/docs) to be used in various tools for drug development. We combined various semantic web resources with the newly converted WikiPathways content using a variety of SPARQL query types and third-party resources, such as the Open PHACTS API. The ability to use pathway information to form new links across diverse biological data highlights the utility of integrating WikiPathways in the semantic web.

  20. WikiBuild: A New Application to Support Patient and Health Care Professional Involvement in the Development of Patient Support Tools

    Science.gov (United States)

    2011-01-01

    Active patient and public involvement as partners in their own health care and in the development of health services is key to achieving a health care system that is responsive to patients’ needs and values. It promotes better use of the health care system, and improves health outcomes, quality of life and patient satisfaction. By involving patients and health care professionals as partners in the creation and updating of patient health support tools, wikis—highly accessible, interactive vehicles of communication—have the potential to empower users to implement these support tools in daily life. Acknowledging the potential of wikis, and recognizing that they capitalize on the free and open access to information, scientists, opinion leaders and patient advocates have suggested that wikis could help decision-making constituencies improve the delivery of health care. They might also decrease its cost and improve access to knowledge within developing countries. However, little is known about the efficacy of wikis in helping to attain these goals. There is also a need to know more about the intention of patients and health care workers to use wikis, in what circumstances and what factors will influence their use of wikis. In this issue of the Journal of Medical Internet Research, Gupta et al describe how they developed and tested a new wiki-inspired application to improve asthma care. The researchers involved patients with asthma, primary care physicians, pulmonologists and certified asthma educators in the construction of an asthma action plan. Their paper—entitled “WikiBuild: a new online collaboration process for multistakeholder tool development and consensus building”—is the first description of a wiki-inspired technology built to involve patients and health care professionals in the development of a patient support tool. This innovative study has made important contributions toward how wikis could be generalized to involve multiple stakeholders in

    2010-04-01

    Information technology teams in health care are tasked with maintaining a variety of information systems with complex support requirements. In radiology, this includes picture archive and communication systems, radiology information systems, speech recognition systems, and other ancillary systems. Hospital information technology (IT) departments are required to provide 24 x 7 support for these mission-critical systems that directly support patient care in emergency and other critical care departments. The practical know-how to keep these systems operational and diagnose problems promptly is difficult to maintain around the clock. Specific details on infrequent failure modes or advanced troubleshooting strategies may reside with only a few senior staff members. Our goal was to reduce diagnosis and recovery times for issues with our mission-critical systems. We created a knowledge base for building and quickly disseminating technical expertise to our entire support staff. We used an open source, wiki-based, collaborative authoring system internally within our IT department to improve our ability to deliver a high level of service to our customers. In this paper, we describe our evaluation of the wiki and the ways in which we used it to organize our support knowledge. We found the wiki to be an effective tool for knowledge management and for improving our ability to provide mission-critical support for health care IT systems.

The ATLAS e-news are an excellent source of information. Appearing now every month they provide a broad, solid view of what is going on. But I'm greedy; I'd love to be "on-line". When the first End-Cap Toroid moved from hall 180 to the pit I was frustrated. I knew that it was happening but I could only get first pictures and reports a few days later. In the meantime the ECT was lowered into the cavern; no information on this available nowhere up to the this issue of the e-news. Here is my dream: an "ATLAS news ticker", i.e. a web page with the news appearing on the day they happen; just one line of information, possibly with a reference to a picture, a person or a report. My idea isn't new. On the ATLAS web-site for the public we have a window "latest news". But I was disappointed when, until a week ago, the latest news dated from December 2006 !!! Can't we do...

    Full Text Available Large-scale knowledge graphs, such as DBpedia, Wikidata, or YAGO, can be enhanced by relation extraction from text, using the data in the knowledge graph as training data, i.e., using distant supervision. While most existing approaches use language-specific methods (usually for English, we present a language-agnostic approach that exploits background knowledge from the graph instead of language-specific techniques and builds machine learning models only from language-independent features. We demonstrate the extraction of relations from Wikipedia abstracts, using the twelve largest language editions of Wikipedia. From those, we can extract 1.6 M new relations in DBpedia at a level of precision of 95%, using a RandomForest classifier trained only on language-independent features. We furthermore investigate the similarity of models for different languages and show an exemplary geographical breakdown of the information extracted. In a second series of experiments, we show how the approach can be transferred to DBkWik, a knowledge graph extracted from thousands of Wikis. We discuss the challenges and first results of extracting relations from a larger set of Wikis, using a less formalized knowledge graph.

    Full Text Available This article focuses on user experiences on reading location-aware news on the mobile platform and aims to explore what experiences this kind of locative journalism generates and how such experiences change the users’ social interaction with news. We produced a specially designed mobile application and tailored news stories specific to this project called LocaNews in order to explore participants’ relation to the content in this journalistic format. The result is generated through a field study and a questionnaire of 32 people to find out how they experience the news presented in this format. The user participants’ responses are analyzed based on their news experiences, contextualizing places and their social interaction with the news within this form of journalism. Results showed that the local, semi-local and non-local user approaches the locative news in a different manner, but that the average user found this kind of news more interesting and more informative than ordinary news. The participants also have a problem identifying this as journalism, rather than an information service.

    Full Text Available Background: The need for informatics and genomics training in pathology is critical, yet limited resources for such training are available. In this study we sought to critically test the hypothesis that the incorporation of a wiki (a collaborative writing and publication tool with roots in "Web 2.0" in a combined informatics and genomics course could both (1 serve as an interactive, collaborative educational resource and reference and (2 actively engage trainees by requiring the creation and sharing of educational materials. Materials and Methods: A 2-week full-time course at our institution covering genomics, research, and pathology informatics (GRIP was taught by 36 faculty to 18 second- and third-year pathology residents. The course content included didactic lectures and hands-on demonstrations of technology (e.g., whole-slide scanning, telepathology, and statistics software. Attendees were given pre- and posttests. Residents were trained to use wiki technology (MediaWiki and requested to construct a wiki about the GRIP course by writing comprehensive online review articles on assigned lectures. To gauge effectiveness, pretest and posttest scores for our course were compared with scores from the previous 7 years from the predecessor course (limited to informatics given at our institution that did not utilize wikis. Results: Residents constructed 59 peer-reviewed collaborative wiki articles. This group showed a 25% improvement (standard deviation 12% in test scores, which was greater than the 16% delta recorded in the prior 7 years of our predecessor course (P = 0.006. Conclusions: Our use of wiki technology provided a wiki containing high-quality content that will form the basis of future pathology informatics and genomics courses and proved to be an effective teaching tool, as evidenced by the significant rise in our resident posttest scores. Data from this project provide support for the notion that active participation in content creation

    Background Collaborative writing applications (eg, wikis and Google Documents) hold the potential to improve the use of evidence in both public health and health care. The rapid rise in their use has created the need for a systematic synthesis of the evidence of their impact as knowledge translation (KT) tools in the health care sector and for an inventory of the factors that affect their use. Objective Through the Levac six-stage methodology, a scoping review was undertaken to explore the depth and breadth of evidence about the effective, safe, and ethical use of wikis and collaborative writing applications (CWAs) in health care. Methods Multiple strategies were used to locate studies. Seven scientific databases and 6 grey literature sources were queried for articles on wikis and CWAs published between 2001 and September 16, 2011. In total, 4436 citations and 1921 grey literature items were screened. Two reviewers independently reviewed citations, selected eligible studies, and extracted data using a standardized form. We included any paper presenting qualitative or quantitative empirical evidence concerning health care and CWAs. We defined a CWA as any technology that enables the joint and simultaneous editing of a webpage or an online document by many end users. We performed qualitative content analysis to identify the factors that affect the use of CWAs using the Gagnon framework and their effects on health care using the Donabedian framework. Results Of the 111 studies included, 4 were experimental, 5 quasi-experimental, 5 observational, 52 case studies, 23 surveys about wiki use, and 22 descriptive studies about the quality of information in wikis. We classified them by theme: patterns of use of CWAs (n=26), quality of information in existing CWAs (n=25), and CWAs as KT tools (n=73). A high prevalence of CWA use (ie, more than 50%) is reported in 58% (7/12) of surveys conducted with health care professionals and students. However, we found only one

    Aiming at providing a comprehensive assessment of the water-energy nexus, the National Energy-Water System (NEWS) project requires the integration of data to support a modeling framework that links climate, hydrological, power production, transmission, and economical models. Large amounts of Georeferenced data has to be streamed to the components of the inter-disciplinary model to explore future challenges and tradeoffs in the US power production, based on climate scenarios, power plant locations and technologies, available water resources, ecosystem sustainability, and economic demand. We used open source and in-house build software components to build a system that addresses two major data challenges: On-the-fly re-projection, re-gridding, interpolation, extrapolation, nodata patching, merging, temporal and spatial aggregation, of static and time series datasets in virtually any file formats and file structures, and any geographic extent for the models I/O, directly at run time; Comprehensive data management based on metadata cataloguing and discovery in repositories utilizing the MAGIC Table (Manipulation and Geographic Inquiry Control database). This innovative concept allows models to access data on-the-fly by data ID, irrespective of file path, file structure, file format and regardless its GIS specifications. In addition, a web-based information and computational system is being developed to control the I/O of spatially distributed Earth system, climate, and hydrological, power grid, and economical data flow within the NEWS framework. The system allows scenario building, data exploration, visualization, querying, and manipulation any loaded gridded, point, and vector polygon dataset. The system has demonstrated its potential for applications in other fields of Earth science modeling, education, and outreach. Over time, this implementation of the system will provide near real-time assessment of various current and future scenarios of the water-energy nexus.

    Full Text Available Este capítulo expone y analiza una experiencia piloto de uso de Wikis para la enseñanza de las prácticas artísticas vinculadas a los nuevos medios de comunicación digital. El denominado "Media Art Wiki" constituye un recurso para la enseñanza del Arte y la Estética de los nuevos medios en un contexto de enseñanza-aprendizaje virtual como es la Universitat Oberta de Catalunya (UOC. Los objetivos iniciales del proyecto consistieron en generar un entorno dinámico de documentación multimedia de las prácticas de Arte de los nuevos medios, y a su vez, que ese espacio de contenidos abiertos pudiera alimentarse de la acción participativa y colaborativa de los estudiantes de las diferentes asignaturas implicadas, contribuyendo de este modo a un enfoque interdisciplinar de la materia común. El Media Art Wiki pretende innovar dentro del aula virtual en cuatro aspectos diferentes: proceso, formato, estructura y contenidos tratando de responder asimismo a un planteamiento pedagógico, que vincule cada una de las actividades implicadas en el Wiki con varios programas y asignaturas. En este capítulo intentaremos dar cuenta de las implicaciones del uso de este tipo de herramientas en la enseñanza universitaria, estructurando el texto en diferentes apartados que, por un lado, trazan el contexto a partir del cual surgió el proyecto, sus necesidades, objetivos y motivaciones dentro del marco teórico del aprendizaje significativo- y el contexto -modelo de enseñanza-aprendizaje- de la UOC. Por otro lado procedemos a la descripción técnica y de contenido del proyecto, así como el diseño de la estrategia didáctica y de las actividades a desarrollar por los estudiantes a corto y medio plazo. Finalmente exponemos la evaluación de dicha experiencia desde la perspectiva de los docentes y los estudiantes para llegar a plantear nuestras conclusiones y posibilidades de desarrollos de futuro.

  3. Wiki-pi: a web-server of annotated human protein-protein interactions to aid in discovery of protein function.

    Directory of Open Access Journals (Sweden)

    Naoki Orii

    Full Text Available Protein-protein interactions (PPIs are the basis of biological functions. Knowledge of the interactions of a protein can help understand its molecular function and its association with different biological processes and pathways. Several publicly available databases provide comprehensive information about individual proteins, such as their sequence, structure, and function. There also exist databases that are built exclusively to provide PPIs by curating them from published literature. The information provided in these web resources is protein-centric, and not PPI-centric. The PPIs are typically provided as lists of interactions of a given gene with links to interacting partners; they do not present a comprehensive view of the nature of both the proteins involved in the interactions. A web database that allows search and retrieval based on biomedical characteristics of PPIs is lacking, and is needed. We present Wiki-Pi (read Wiki-π, a web-based interface to a database of human PPIs, which allows users to retrieve interactions by their biomedical attributes such as their association to diseases, pathways, drugs and biological functions. Each retrieved PPI is shown with annotations of both of the participant proteins side-by-side, creating a basis to hypothesize the biological function facilitated by the interaction. Conceptually, it is a search engine for PPIs analogous to PubMed for scientific literature. Its usefulness in generating novel scientific hypotheses is demonstrated through the study of IGSF21, a little-known gene that was recently identified to be associated with diabetic retinopathy. Using Wiki-Pi, we infer that its association to diabetic retinopathy may be mediated through its interactions with the genes HSPB1, KRAS, TMSB4X and DGKD, and that it may be involved in cellular response to external stimuli, cytoskeletal organization and regulation of molecular activity. The website also provides a wiki-like capability allowing users

    The media affects individuals' behaviors, especially by means of news and advertisements. In this study, we evaluated health content of organ donation and transplantation news in the printed media and on television programs for a 1-year period in Turkey. We examined 2449 news items in 230 newspapers and magazines; 1179 news programs on 45 television channels, all concerning organ donation and transplantation. The news obtained from the Media Pursuit Center were transferred to an electronic file to evaluate the format and content of the news. Nine variables were examined about the scope and the formal characteristics of the news: the publication name, its type, the province, the date, the headline, the title length, the presence of a photograph, or its kind, the news size, and the page number. In the content analysis of the news, we also examined 9 variables: the topic, the message of the headline, the property of the words in the title, the identification of photographs in the news, the age, gender of actors in the news, as well as donor or recipient. In a summary, print media and television channels, failed to show sufficient information about organ donation and transplantation. The percentage of news about organ donation and transplantation was small and mostly negative items in the media. On television channels, sufficient place was not given to organ donation and transplantation. The news in printed media and on television channels was not about motivated or altruistic behavior. The pattern of organ donation and transplantation news is important in terms of perception and comment by the public. Furthermore it directly affects the perception of the news by the reader.

    Full Text Available The present study aimed to compare discursive strategies employed by two international news agencies including Euro News and BBC. Van Dijk’s (2004 model of CDA was adopted. Thirty pieces of news about internal affairs of Iran together with their Persian translations were downloaded from the corresponding website, i.e. 30 pieces of English news and their corresponding Persian translations from the Euro News website and 30 pieces of English news with their corresponding translations from the BBC website. The frequency of lexical items was observed to not differ significantly. Two sets of translations were compared to their source texts based on four discursive strategies of hyperbole, polarization, vagueness and euphemism. An independent-samples t-test was conducted to compare the frequency of strategies applied by the two news agencies. Results revealed no significant difference between the two agencies except for the discursive strategy of vagueness.

    There are few data available on how physicians inform patients about bad news. We surveyed internists about how they convey this information. We surveyed internists about their activities in giving bad news to patients. One set of questions was about activities for the emotional support of the patient (11 items), and the other was about activities for creating a supportive environment for delivering bad news (9 items). The impact of demographic factors on the performance of emotionally supportive items, environmentally supportive items, and on the number of minutes reportedly spent delivering news was analyzed by analysis of variance and multiple regression analysis. More than half of the internists reported that they always or frequently performed 10 of the 11 emotionally supportive items and 6 of the 9 environmentally supportive items while giving bad news to patients. The average time reportedly spent in giving bad news was 27 minutes. Although training in giving bad news had a significant impact on the number of emotionally supportive items reported (P woman, unmarried, and having a history of major illness were also associated with reporting a greater number of emotionally supportive activities. Internists report that they inform patients of bad news appropriately. Some deficiencies exist, specifically in discussing prognosis and referral of patients to support groups. Physician educational efforts should include discussion of prognosis with patients as well as the availability of support groups.

But if so, how will news come to the Internetconnected cellphones? In accordance with the distinction, already drawn in 1997, between push and pull technologies as two different forms of how content is delivered to the end users, cellphones are characterized as push devices (passive reception, in opposition to computers, classified as pull devices (active reception. The news items that fit cellphones are pushed news. And they will be pushed as SMS, e-mails, tweets and through news aggregators.

    Kline, Susan L; Chatterjee, Karishma; Karel, Amanda I

    2009-01-01

    Given that the public uses the media to learn about adoption as a family form, this study analyzes U.S. television news coverage of adoption between 2001 and 2005 (N = 309 stories), to identify the types of news events covered about adoption. A majority of news stories covered fraud, crime, legal disputes, and negative international adoption cases. Adoptees as defective or unhealthy were depicted more in negative news event stories, birth parents appeared less overall, and adoptive parents were most likely to have healthy depictions in positively oriented adoption experience, big family, and reunion stories. Although three quarters of the stories used primary adoption participants as news sources, one-third of the negative event stories did not contain healthy depictions of adoption participants. The authors discuss ways journalists and researchers might improve adoption news coverage.

    Full Text Available We investigate the dynamic cross-correlations between mass media news, new media news, and stock returns for the SSE 50 Index in Chinese stock market by employing the MF-DCCA method. The empirical results show that (1 there exist power-law cross-correlations between two types of news as well as between news and its corresponding SSE 50 Index return; (2 the cross-correlations between mass media news and SSE 50 Index returns show larger multifractality and more complicated structures; (3 mass media news and new media news have both complementary and competitive relationships; (4 with the rolling window analysis, we further find that there is a general increasing trend for the cross-correlations between the two types of news as well as the cross-correlations between news and returns and this trend becomes more persistent over time.

  17. Virtual strategies to improve transversal competences, using wikis in a collaborative work

    2016-04-01

    A major educational aim in university degrees since the implementation of the European Credit Transfer System (ECTS) on the European universities is the work based on transversal competences. However, the first course students arrive at the Spanish universities with important deficiencies on some of these competences, especially regarding on oral and written expression, time management and collaborative work. The experience of the teachers involved in this work has revealed the coordination difficulty between the students to work in group, important deficiencies on information management and the stress caused by the oral presentations. The results presented here correspond to a teaching innovation project. It is based on: a) the development of works in groups of 3 or 4 students, proposed as flipped classrooms strategy and b) the implementation of a virtual tool (a wiki). This tool helps the students with scientific information management and facilitates the access of all the students belonging to the work group at the information provided by colleagues. The wiki also improves the monitoring and evaluation of the work and contributions of each student by teachers. Each group must develop a topic related to the subject - General Geology and Geochemistry - that the group chose from a list of earth sciences topics proposed by teachers. The resulting works are presented in poster and oral presentations (10 min. per group and 5 min. for questions). Each work is evaluated by teachers using the evidences provided on the wiki and by means of evaluation guides. Moreover, the students must self and co-evaluate the presented works. The implementation of this project has provided information to analyze the impact of these strategies and to quantify it in terms of 'Learning Analytics'.

    Full Text Available In this article we investigate the impact of social media readership to the editorial profile of newspapers. We analyze tweets containing links to news articles from eight of the largest national newspapers in the United States, United Kingdom, Spain, Brazil, and Germany. The data collection follows the first two weeks of October 2012 and includes 2,842,699 tweets with links to news articles. Twitter-shortened links were resolved using a three-pass routine and assigned to 1 of the 21 newspaper sections. We found the concentration of links to news articles posted by top users to be lower than reported in the literature and the strategy of relaying headlines on Twitter via automatic news aggregators (feeds to be inefficient. The results of this investigation show which sections of a newspaper are the most and least read by readers in different parts of the world, with German readers placing greater emphasis on Politics and Economy; Brazilians on Sports and Arts; Spaniards on Local and National news; Britons and Americans on Opinion and World news. We also found that German and Spanish readers are more likely to read multiple national newspapers, while British readers more often resort to foreign sources of news. The results confirm that feedback to news items from a large user base is pivotal for the replication of content and that newspapers and news items can be clustered according to the editorial profile and principles of newsworthiness inherited from legacy media. The results of this investigation shed light onto the networked architecture of journalism that increasingly depends on readership agency.

    2011-02-01

    Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

    Hierarchical organization is prevalent in networks representing a wide range of systems in nature and society. An important example is given by the tag hierarchies extracted from large on-line data repositories such as scientific publication archives, file sharing portals, blogs, on-line news portals, etc. The tagging of the stored objects with informative keywords in such repositories has become very common, and in most cases the tags on a given item are free words chosen by the authors independently. Therefore, the relations among keywords appearing in an on-line data repository are unknown in general. However, in most cases the topics and concepts described by these keywords are forming a latent hierarchy, with the more general topics and categories at the top, and more specialized ones at the bottom. There are several algorithms available for deducing this hierarchy from the statistical features of the keywords. In the present work we apply a recent, co-occurrence-based tag hierarchy extraction method to sets of keywords obtained from four different on-line news portals. The resulting hierarchies show substantial differences not just in the topics rendered as important (being at the top of the hierarchy) or of less interest (categorized low in the hierarchy), but also in the underlying network structure. This reveals discrepancies between the plausible keyword association frameworks in the studied news portals.

    2017-12-01

    To characterize online news coverage relating to mammography, including articles' stance toward screening mammography. Google News was used to search U.S. news sites over a 9-year period (2006-2015) based on the search terms "mammography" and "mammogram." The top 100 search results were recorded. Identified articles were manually reviewed. The top 100 news articles were from the following sources: local news outlet (50%), national news outlet (24%), nonimaging medical source (13%), entertainment or culture news outlet (6%), business news outlet (4%), peer-reviewed journal (1%), and radiology news outlet (1%). Most common major themes were the screening mammography controversy (29%), description of a new breast imaging technology (23%), dense breasts (11%), and promotion of a public screening initiative (11%). For the most recent year, article stance toward screening mammography was 59%, favorable; 16%, unfavorable; and 25%, neutral. After 2010, there was an abrupt shift in articles' stances from neutral to both favorable and unfavorable. A wide range of online news sources addressed a range of issues related to mammography. National, rather than local, news sites were more likely to focus on the screening controversy and more likely to take an unfavorable view. The controversial United States Preventive Services Task Force guidelines may have influenced articles to take a stance on screening mammography. As such online news may impact public perception of the topic and thus potentially impact guideline adherence, radiologists are encouraged to maintain awareness of this online coverage and to support the online dissemination of reliable and accurate information.

  18. Thrilling News Revisited: The Role of Suspense for the Enjoyment of News Stories.

    Science.gov (United States)

    Kaspar, Kai; Zimmermann, Daniel; Wilbers, Anne-Kathrin

    2016-01-01

    Previous research on news perception has been dominated by a cognitively oriented perspective on reception processes, whereas emotions have been widely neglected. Consequently, it has remained open which features of a news story might elicit affective responses and hence modulate news perception, shifting the focus to the emotional potential of the narrative. According to the affective-disposition theory, the experience of suspense is the striving force of immersion in fictional dramas. Thereby, a positive affective disposition toward the protagonist of a story and a high likelihood of a bad ending should increase suspense that, in turn, should positively influence reading appreciation and lingering interest in the story. We investigated whether suspense and its determinants also play such a key role in the context of news stories. Study 1 ( n = 263) successfully replicated results of an earlier study, whereas Studies 2 ( n = 255) and 3 ( n = 599) challenged the generalizability of some effects related to manipulated characteristics of a news story. In contrast, correlational relationships between perceived news characteristics and news evaluation were relatively stable. In particular, participants' liking of the protagonist and the perceived likelihood of a good ending were positively associated with suspense, reading appreciation, and lingering interest. This result indicates a preference for happy endings and contradicts the notion that likely negative outcomes are beneficial for suspense and the enjoyment of news stories, as postulated by the affective-disposition theory in the context of fictional dramas. Moreover, experienced suspense reliably mediated the correlations between, on the one hand, participants' liking of the protagonist and the perceived likelihood of a good ending and, on the other hand, reading appreciation and lingering interest. The news story's personal relevance was less influential than expected. Further, we observed a large absence of

  5. Thrilling news revisited: The role of suspense for the enjoyment of news stories

    Directory of Open Access Journals (Sweden)

    Kai Kaspar

    2016-12-01

    Full Text Available Previous research on news perception has been dominated by a cognitively oriented perspective on reception processes, whereas emotions have been widely neglected. Consequently, it has remained open which features of a news story might elicit affective responses and hence modulate news perception, shifting the focus to the emotional potential of the narrative. According to the affective-disposition theory, the experience of suspense is the striving force of immersion in fictional dramas. Thereby, a positive affective disposition toward the protagonist of a story and a high likelihood of a bad ending should increase suspense that, in turn, should positively influence reading appreciation and lingering interest in the story. We investigated whether suspense and its determinants also play such a key role in the context of news stories. Study 1 (n = 263 successfully replicated results of an earlier study, whereas Studies 2 (n = 255 and 3 (n = 599 challenged the generalizability of some effects related to manipulated characteristics of a news story. In contrast, correlational relationships between perceived news characteristics were relatively stable. In particular, a higher liking of the protagonist and a higher perceived likelihood of a good versus bad ending were positively associated with suspense, reading appreciation, and lingering interest. This result indicates a preference for happy endings and it contradicts the notion that likely negative outcomes are beneficial for suspense and the enjoyment of news stories, as postulated by the affective-disposition theory in the context of fictional dramas. Moreover, experienced suspense reliably mediated the correlations between, on the one hand, participants’ liking of the protagonist and the perceived likelihood of a good ending and, on the other hand, reading appreciation and lingering interest. The news story’s personal relevance was less influential than expected. Further, we observed a large

    Jørndrup, Hanne; Bentsen, Martine

    As newsroom staff around the world went about their day on 25 March 2015, hundreds of volunteers located in over 100 countries gathered to monitor their news media as part of the Fifth Global Media Monitoring Project (GMMP). The Global Media Monitoring Project (GMMP) is the world’s longest......-running and most extensive research on gender in the news media. It began in 1995 when volunteers in 71 countries around the world monitored women’s presence in their national radio, television and print news. The research revealed that only 17% of news subjects – the people who are interviewed or whom the news...... is about – were women. It found that gender parity was ‘a distant prospect in any region of the world. News [was] more often being presented by women but it [was] still rarely about women.

    2016-01-01

    People living with complex regional pain syndrome (CRPS) experience frustration with the lack of knowledge and understanding of CRPS as a pain condition. We report on our attempt to address this issue. People living with CRPS taking part in a larger study were invited to co-construct a CRPS wiki page that addressed the areas in which they had experienced the most difficulty. A blank wiki page was set up for participants to populate with issues they felt needed to be raised and addressed. Participants failed to engage with the wiki technology. We modified our procedure and completed an inductive analysis of a sister-forum which participants were using as part of the larger study. Six issues of importance were identified. We used the discussion forum threads to populate the themes. Due to a continued lack of engagement with the wiki technology, the team decided to create a suite of leaflets which were piloted with delegates at a CRPS patient conference. Future work should be mindful of the extent to which patients are able and willing to share their experiences through such technology. Striking the balance between patient-endorsed and researcher-driven co-creation of such material is imperative.

Twitter is interesting in this context as it has been shown to present both the characteristics social and news media. The basic measure of virality in Twitter is the probability of retweet. Twitter...... is different from email in that retweeting does not depend on pre-existing social relations, but often occur among strangers, thus in this respect Twitter may be more similar to traditional news media. We therefore hypothesize that negative news content is more likely to be retweeted, while for non-news tweets...

    2012-01-01

    With the advent of specialized television channels offering 24-hour coverage, Internet and smart phones, the possibility to be constantly in contact with the media has increased dramatically in the last decades. Despite this higher access to knowledge, the impact media exposure has on healthy individuals remains poorly studied. Given that most information conveyed in the media is negative and that upon perception of threat, the brain activates the stress system, which leads to cortisol secretion, we decided to determine how healthy individuals react to media information. Accordingly, we investigated whether reading real negative news (1) is physiologically stressful, (2) modulates one's propensity to be stress reactive to a subsequent stressor and (3) modulates remembrance for these news. Sixty participants (30 women, 30 men) were randomly assigned to either twenty-four real neutral news excerpts or to twenty-four real negative excerpts for 10 minutes. They were then all exposed to a well-validated psychosocial stressor, the Trier Social Stress Test (TSST), which consists of an anticipation phase of 10 minutes and a test phase of 10 minutes. A total of eight salivary cortisol samples were collected, at 10-minutes intervals, throughout the experimental procedure. One day later, a free recall of the news was performed. Results showed that although reading negative news did not lead to change in cortisol levels (p>0.05), it led to a significant increase in cortisol to a subsequent stressor in women only (pnegative news condition experienced better memory for these news excerpts compared to men (pmedia exposure could increase stress reactivity and memory for negative news in women.

    Full Text Available This paper evaluates the usefulness of the civil disobedience theory to legitimate the e-leaking of secrets, i.e. ethical and electronic disclosure of confidential information. First, the main definitions of offline civil disobedience are reviewed. Liberalism established the dominant set of validity conditions: symbolic, peaceful, responsible, public, constitutionally loyal, etc. We criticize this standpoint thanks to the discursive approach, but also highlighting its prejudices. Second, we analyse whether WikiLeaks meets those classical requirements. Encrypted anonymity, partial decriminalization and limited irresponsibility become acceptable. Regarding publicity, the disobedient visualization of a political conflict can be satisfied without revealing the identity of its participants.

  20. News Authorship and News Sources: Impacts on Environmental Coverage in The Nigerian Press

    Directory of Open Access Journals (Sweden)

    Ogadimma C. Emenyeonu

    2017-07-01

    Full Text Available This study examines the impacts of news authorship and news sources on environmental coverage in the Nigerian press to shed light on the roles they play in news construction. The study finds that journalists in conjunction with policy makers are the catalyst for environmental information, whereas citizens who are pivotal in creating relevant public opinion on environmental issues are left behind. The study reveals that investigative reporting lacks in environmental coverage because most coverage are events driven which explains why environmental news is reported as straight news and as such journalists rely heavily on official sources rather than subsidiary sources. The study opines that for proper environmental coverage, journalists must choose sources from both main and subsidiary actors and revert to proactive, investigative and interpretive reporting so as to make environmental stories relatable to the intended audiences.

    We find that on average an announcement of rising unemployment is 'good news' for stocks during economic expansions and 'bad news' during economic contractions. Thus stock prices usually increase on news of rising unemployment, since the economy is usually in an expansion phase. We provide an explanation for this phenomenon. Unemployment news bundles two primitive types of information relevant for valuing stocks: information about future interest rates and future corporate earnings and divide...

  12. When Sound Bites Become the News: a Case Study on Manufacturing News in Croatia

    Directory of Open Access Journals (Sweden)

    Tena Perišin

    2017-06-01

    Full Text Available Media environment is rapidly changing and facing a widespread crisis in journalism. It is followed by the decline of audience trust and increasing market pressures. The main goal is to win the audience’s attention, very often by creating drama and producing ‘conflict’. The news is not based on something that really happened and that is relevant, but it is more often manufactured or artificially produced. In this case study we explore the curious life cycle of a sound bite from a passing remark by the then Croatian Prime Minister Zoran Milanović’s to the headlines, discussions and extensive reports which developed over the course of several days. This example shows how news could be manufactured and content blurred when it is built around a fragment without providing the context, in this case a political quote. For several days, politicians, experts, war veterans, but also ordinary citizens were involved in the manufactured news story without making a reference to the context. Consequently, the democratic debate was avoided. Drawing on a discussion of news fragmentation as isolation from context, we show that in this case, news values (what news is are increasingly blurred, preventing the news from becoming the source of information and discussion of the country’s key issues.

    The Dermatology Education Wiki (dermwiki) website serves as a resource platform for medical students and residents. The readily accessible interface provides dermatology articles, survival guides, didactic lectures, and links to faculty talks as well as research opportunities. To assess medical student and resident satisfaction with the dermwiki website. Fourth-year medical students taking a dermatology elective were provided with a temporary password to access relevant dermwiki information. A satisfaction survey was created to assess whether medical students found the website helpful. Second- and third-year dermatology residents were also surveyed to compare satisfaction scores prior to and after the introduction of the dermwiki website. End-of-rotation medical student exam scores were tabulated and compared to the average scores from years prior to the development of the dermwiki website. Medical students rated the dermatology elective with the dermwiki website higher than rotations without a wiki (8.12 vs 7.31). Students planning to go into dermatology were more satisfied with the dermwiki website, reported accessing the website more frequently (11 times vs 9.5 times), and reported more time spent studying (12.2 hours vs 6.7 hours) than students not going into dermatology. End-of-rotation medical student exam scores did not differ from those prior to the development of the demwiki website. Ten second- and third-year dermatology residents unanimously stated that they were more satisfied with the program after the institution of the dermwiki website. Overall, addition of the dermwiki website to the dermatology elective curriculum has improved medical student and resident satisfaction scores. The improvement is greater among students planning to enter the field of dermatology. This study serves as a model for the incorporation of internet-based interactive tools to transform and supplement the learning environment.

    Even democracies endowed with the most active free press struggle to maintain diversity of news coverage. Consolidation and market forces may cause only a few dominant players to control the news cycle. Editorial policies may be biased by corporate ownership relations, narrowing news coverage and focus. To an increasing degree this problem also applies to social media news distribution, since it is subject to the same socio-economic drivers. To study the effects of consolidation and ownership on news diversity, we model the diversity of Chilean coverage on the basis of ownership records and social media data. We create similarity networks of news outlets on the basis of their ownership and the topics they cover. We then examine the relationships between the topology of ownership networks and content similarity to characterize how ownership affects news coverage. A network analysis reveals that Chilean media is highly concentrated both in terms of ownership as well as in terms of topics covered. Our method can be used to determine which groups of outlets and ownership exert the greatest influence on news coverage.

    Full Text Available Abstract Background The Neighborhood Environment Walkability Scale (NEWS and its abbreviated form (NEWS-A assess perceived environmental attributes believed to influence physical activity. A multilevel confirmatory factor analysis (MCFA conducted on a sample from Seattle, WA showed that, at the respondent level, the factor-analyzable items of the NEWS and NEWS-A measured 11 and 10 constructs of perceived neighborhood environment, respectively. At the census blockgroup (used by the US Census Bureau as a subunit of census tracts level, the MCFA yielded five factors for both NEWS and NEWS-A. The aim of this study was to cross-validate the individual- and blockgroup-level measurement models of the NEWS and NEWS-A in a geographical location and population different from those used in the original validation study. Methods A sample of 912 adults was recruited from 16 selected neighborhoods (116 census blockgroups in the Baltimore, MD region. Neighborhoods were stratified according to their socio-economic status and transport-related walkability level measured using Geographic Information Systems. Participants self-completed the NEWS. MCFA was used to cross-validate the individual- and blockgroup-level measurement models of the NEWS and NEWS-A. Results The data provided sufficient support for the factorial validity of the original individual-level measurement models, which consisted of 11 (NEWS and 10 (NEWS-A correlated factors. The original blockgroup-level measurement model of the NEWS and NEWS-A showed poor fit to the data and required substantial modifications. These included the combining of aspects of building aesthetics with safety from crime into one factor; the separation of natural aesthetics and building aesthetics into two factors; and for the NEWS-A, the separation of presence of sidewalks/walking routes from other infrastructure for walking. Conclusion This study provided support for the generalizability of the individual

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

  18. Displaying fairness while delivering bad news: Testing the effectiveness of organizational bad news training in the layoff context.

    Richter, Manuela; König, Cornelius J; Koppermann, Christopher; Schilling, Michael

    2016-06-01

    Although giving bad news at work is a stressful experience, managers are often underprepared for this challenging task. As a solution, we introduce organizational bad news training that integrates (a) principles of delivering bad news from the context of health care (i.e., bad news delivery component), and (b) principles of organizational justice theory (i.e., fairness component). We argue that both the formal and fair delivery of bad news at work can be enhanced with the help of training to mitigate distress both for the messenger and the recipient. We tested the effectiveness of training for the delivery of a layoff as a typical bad news event at work. In 2 studies, we compared the performance of a training group (receiving both components of training) with that of a control group (Study 1, Study 2) and a basics group (receiving the bad news delivery component only; Study 2) during a simulated dismissal notification meeting. In general, the results supported our hypotheses: Training improved the formal delivery of bad news and predicted indicators of procedural fairness during the conversation in both studies. In Study 2, we also considered layoff victims' negativity after the layoff and found that training significantly reduced negative responses. This relationship was fully mediated by layoff victims' fairness perceptions. Despite preparation, however, giving bad news remained a challenging task in both studies. In summary, we recommend that organizations provide managers with organizational bad news training in order to promote professional and fair bad news conversations at work.

    In a regional hospital, many patients are newly diagnosed with cancer. Breaking the bad news in these patients and their relatives is a tough task. Many doctors are not experienced in talking to patients about death or death-related diseases. In recent years, there have been great efforts to change the current situation. The aim of this study was to investigate the experience and education of medical personnel in breaking bad news in a secondary hospital. 59 doctors from General Hospital of Komotini, Greece were included in the study. All the doctors were in clinical specialties that treated cancer patients. A brief questionnaire was developed based on current guidelines such as Baile/SPIKES framework and the ABCDE mnemonic. Residents are involved in delivering bad news less frequently than specialists. Only 21 doctors (35.59%) had specific training on breaking bad news. 20 doctors (33.90%) were aware of the available techniques and protocols on breaking bad news. 47 doctors (79.66%) had a consistent plan for breaking bad news. 57 (96.61%) delivered bad news in a quiet place, 53 (89.83%) ensured no interruptions and enough time, 53 (89.83%) used simple words and 54 (91.53%) checked for understanding and did not rush through the news. 46 doctors (77.97%) allowed relatives to determine patient's knowledge about the disease. There were low rates of specific training in breaking bad news. However, the selected location, the physician's speech and their plan were according to current guidelines.

    The purpose of this review is to summarize the key findings which prove that the biased perceptions of viewers may provide an inaccurate image of the informational validity of televised news. The news may generate distorted recollections of what occurred in particular reported events if displayed routines influence viewers not to pay attention to the essential features of a narrative. Elaborating on Fiske and Hartley (2010), Zelizer (2010), and Gunter (2015), we indicate that the character of the news setting has altered and individuals' news consumption routines have changed in adapting to media advancements. The news may be undergone at various psychological stages by news publics. Televised news may transmit information undeviatingly to publics that may (not) be committed successfully to memory. Our paper shows that individuals' skills to handle information that is displayed in a linguistic configuration are influenced by their abilities in the utilization of certain symbol systems that are employed to represent notions and meanings. Televised news may shape what individuals grasp, influence their perceptions, convictions, and views regarding prevailing events and matters, and transmit knowledge and interpretation. If news stories can be jotted down in a linguistic style that sidesteps making needless processing demands and captivate news users by facilitating them to make connections with former knowledge, they may be more worthy of note and more edifying. We conclude that news narratives present a cognitive demanding task to individuals, displaying novel information regarding evolving events in a multifarious format. Broadcast news exhibits intricate contents, displaying configurations that employ excessively the cognitive abilities for information processing of viewers.

    Full Text Available The analysis of news in the financial context has gained a prominent interest in the last years. This is because of the possible predictive power of such content especially in terms of associated sentiment/mood. In this paper, we focus on a specific aspect of financial news analysis: how the covered topics modify according to space and time dimensions. To this purpose, we employ a modified version of topic model LDA, the so-called Structural Topic Model (STM, that takes into account covariates as well. Our aim is to study the possible evolution of topics extracted from two well known news archive—Reuters and Bloomberg—and to investigate a causal effect in the diffusion of the news by means of a Granger causality test. Our results show that both the temporal dynamics and the spatial differentiation matter in the news contagion.

    Full Text Available In the last couple of decades there has been an unprecedented explosion of news media platforms and formats, as a succession of digital and social media have joined the ranks of legacy media. We live in a ‘hybrid media system’ (Chadwick, 2013, in which people build their cross-media news repertoires from the ensemble of old and new media available. This article presents an innovative mixed-method approach with considerable explanatory power to the exploration of patterns of news media consumption. This approach tailors Q-methodology in the direction of a qualitative study of news consumption, in which a card sorting exercise serves to translate the participants’ news media preferences into a form that enables the researcher to undertake a rigorous factor-analytical construction of their news consumption repertoires. This interpretive, factor-analytical procedure, which results in the building of six audience news repertoires in Denmark, also preserves the qualitative thickness of the participants’ verbal accounts of the communicative figurations of their day-in-the-life with the news media.

    In 2013 Australia introduced Wiki-based Clinical Practice Guidelines for the Management of Adult Onset Sarcoma. These guidelines utilized a customized MediaWiki software application for guideline development and are the first evidence-based guidelines for clinical management of sarcoma. This paper presents our experience with developing and implementing web-based interactive guidelines and reviews some of the challenges and lessons from adopting an evidence-based (rather than consensus-based) approach to clinical sarcoma guidelines. Digital guidelines can be easily updated with new evidence, continuously reviewed and widely disseminated. They provide an accessible method of enabling clinicians and consumers to access evidence-based clinical practice recommendations and, as evidenced by over 2000 views in the first four months after release, with 49% of those visits being from countries outside of Australia. The lessons learned have relevance to other rare cancers in addition to the international sarcoma community. PMID:25784832

    Full Text Available Online news reading has become a widely popular way to read news articles from news sources around the globe. With the enormous amount of news articles available, users are easily overwhelmed by information of little interest to them. News recommender systems help users manage this flood by recommending articles based on user interests rather than presenting articles in order of their occurrence. We present our research on developing personalized news recommendation system with the help of a popular micro-blogging service, “Twitter.” News articles are ranked based on the popularity of the article identified from Twitter’s public timeline. In addition, users construct profiles based on their interests and news articles are also ranked based on their match to the user profile. By integrating these two approaches, we present a hybrid news recommendation model that recommends interesting news articles to the user based on their popularity as well as their relevance to the user profile.

  14. Delivering bad news in emergency care medicine.

    Maynard, Douglas W

    2017-01-01

    Forecasting is a strategy for delivering bad news and is compared to two other strategies, stalling and being blunt. Forecasting provides some warning that bad news is forthcoming without keeping the recipient in a state of indefinite suspense (stalling) or conveying the news abruptly (being blunt). Forecasting appears to be more effective than stalling or being blunt in helping a recipient to "realize" the bad news because it involves the deliverer and recipient in a particular social relation. The deliverer of bad news initiates the telling by giving an advance indication of the bad news to come; this allows the recipient to calculate the news in advance of its final presentation, when the deliverer confirms what the recipient has been led to anticipate. Thus, realization of bad news emerges from intimate collaboration, whereas stalling and being blunt require recipients to apprehend the news in a social vacuum. Exacerbating disruption to recipients' everyday world, stalling and being blunt increase the probability of misapprehension (denying, blaming, taking the situation as a joke, etc.) and thereby inhibit rather than facilitate realization. Particular attention is paid to the "perspective display sequence", a particular forecasting strategy that enables both confirming the recipient's perspective and using that perspective to affirm the clinical news. An example from acute or emergency medicine is examined at the close of the paper.

En la primera parte de este artículo se expone el pensamiento actualizado que empíricamente evoluciona emparejado a la actualidad de nuestras investigaciones. El objetivo es hacer entender el territorio wiki como informado y transparente llamado a añadir capas de información a la realidad para de esta forma no sustituirla sino ampliarla. Seguidamente, en la segunda parte, se describe y analiza la experiencia de innovación llevada a cabo durante el curso 2007/2008 en la que se ensayó un modelo docente instrumentados en los modos y paisajes previamente descritos.

    Full Text Available La Wikipedia va néixer al ciberespai. Els seus primers anys es van caracteritzar per una feina distribuïda i asíncrona entre usuaris de tot el planeta, que amb prou feines tenien relació personal fora de la xarxa. Amb el pas del temps, alguns dels seus voluntaris van fer les anomenades wikitrobades, però al començament les reunions de wikimedistes tenien la finalitat d'estrènyer llaços i no comportaven cap millora directa dels continguts dels projectes. Més endavant van sorgir iniciatives presencials en les quals es van involucrar, a més de voluntaris, algunes entitats culturals; la més recent i que ha tingut més impacte és Wiki Loves Monuments 2011, un concurs destinat a fotografiar monuments de divuit països europeus, entre els quals hi ha Espanya. Gràcies a l'alta participació, s'han pres en conjunt més de 160.000 fotografies de monuments. Espanya ha ocupat el tercer lloc en nombre d'imatges. En aquest article estudiem els orígens de Wiki Loves Monuments, com es va posar en marxa, com es va desenvolupar i els resultats obtinguts. L'èxit de l'edició 2011 i les peticions d'altres països han fet que ja es treballi en l'organització de Wiki Loves Monuments 2012, aquesta vegada a escala mundial.

  17. Bad news: The influence of news coverage and Google searches on Gardasil adverse event reporting.

    Human papilloma virus vaccines are a safe and effective tool for reducing HPV infections that can cause cervical cancer. However, uptake of these vaccines has been suboptimal, with many people holding negative beliefs and misconceptions. Such beliefs have been linked with the experience of unpleasant side effects following medical treatment, and media coverage may heighten such concerns. The present study sought to assess the influence of news coverage (number of news articles per month) on adverse event reporting in response to Gardasil vaccination in New Zealand over a 7.5-year period, and whether the influence of news coverage was mediated by internet search activity (Google search volumes). Multiple linear regression analyses and simple mediation analyses were used, controlling for year and number of vaccinations delivered. News coverage in the previous month, and Google search volumes in the same month, were significant predictors of adverse event reporting, after accounting for vaccination rates and year. Concurrent Google search volumes partially mediated the effect of prior news coverage. The results suggest that some of the adverse events reported were not related to the vaccination itself, but to news coverage and internet search volumes, which may have contributed to public concerns about potentially unpleasant or harmful outcomes. These findings have implications for the importance of psychological and social factors in adverse event reporting, and the role of the news media in disseminating health information.

    2016-02-01

    In this article, a research project on mobile safe food consumption system (FoodWiki) is discussed that performs its own inferencing rules in its own knowledge base. Currently, the developed rules examines the side effects that are causing some health risks: heart disease, diabetes, allergy, and asthma as initial. There are thousands compounds added to the processed food by food producers with numerous effects on the food: to add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so forth. Those commonly used ingredients or compounds in manufactured foods may have many side effects that cause several health risks such as heart disease, hypertension, cholesterol, asthma, diabetes, allergies, alzheimer etc. according to World Health Organization. Safety in food consumption, especially by patients in these risk groups, has become crucial, given that such health problems are ranked in the top ten health risks around the world. It is needed personal e-health knowledge base systems to help patients take control of their safe food consumption. The systems with advanced semantic knowledge base can provide recommendations of appropriate foods before consumption by individuals. The proposed FoodWiki system is using a concept based search mechanism that performs on thousands food compounds to provide more relevant information.

    This paper focus on TV news programs and design a content-based news video browsing and retrieval system, NVRS, which is convenient for users to fast browsing and retrieving news video by different categories such as political, finance, amusement, etc. Combining audiovisual features and caption text information, the system automatically segments a complete news program into separate news stories. NVRS supports keyword-based news story retrieval, category-based news story browsing and generates key-frame-based video abstract for each story. Experiments show that the method of story segmentation is effective and the retrieval is also efficient.

Creemos que sólo así se logrará una verdadera innovación en los procesos de enseñanza/aprendizaje en este nuevo Espacio Europeo de Educación Superior. Una de las innovaciones que la tecnología ofrece es la relacionada con herramientas de software social, donde podemos encontrar la tecnología Wiki como motor de diversas experiencias didácticas en el ámbito universitario. La implantación de herramientas como el Wiki está provocando en el profesorado un proceso de replanteamiento de su racionalidad pedagógica y de sus prácticas docentes. Mediante el presente artículo pretendemos ofrecer un acercamiento a distintas prácticas con Wikis que desde hace algunos años se vienen implantando en la Universidad de Extremadura, en ellas son protagonistas la formación del profesorado, la reflexión del alumnado sobre la propia actividad mediante portafolios y diarios personales y, finalmente, el uso de los Wikis como herramientas para desarrollar aprendizaje colaborativo.

    Full Text Available The theory of creative cycling emerged from my PhD study of news professionals in Norway. The study was carried out according to classic grounded theory principles (Glaser and Strauss 1967, Glaser 1978, 1998, 2001, 2005, and the area of interest was the performance of news journalism in the multimedia age. The theory runs counter to widespread tendencies of industrial age thinking in news media. It emphasizes news professionals’ search for meaning in their daily work, and suggests that their main concern is self-fulfillment through original contribution. The dilemma and resolution, creative cycling, is a basic social process continuously going within inner and outer framings. It consists of three interrelated dimensions: productive processing, breaks and shifts and inspirational looping.

    2013-06-01

    Full Text Available Rhythm is central to news reading in radio and television programs. This paper proposes a three level structure for rhythm in news discourse. It gives a comprehensive definition of rhythm and types of rhythm. Firstly, the Base Rhythm Structure consists of semantic and pragmatic rhythmic accents, coincident with very specific words. Secondly, these accents are grouped together according to type, frequency and order, thereby configuring three types of “rhythmic units” (the Internal Rhythm Structure: starting, main and end units. A last structure level presents four discursive factors that are very important in integrating the overall time structure of news announcing (the Melodic Rhythm Structure. This integral structure for news announcing rhythm should be further tested in acoustic-experimental studies under the criterion of information transmission efficacy.

    Full Text Available Recommending news stories to users, based on their preferences, has long been a favourite domain for recommender systems research. Traditional systems strive to satisfy their user by tracing users' reading history and choosing the proper candidate news articles to recommend. However, most of news websites hardly require any user to register before reading news. Besides, the latent relations between news and microblog, the popularity of particular news, and the news organization are not addressed or solved efficiently in previous approaches. In order to solve these issues, we propose an effective personalized news recommendation method based on microblog user profile building and sub class popularity prediction, in which we propose a news organization method using hybrid classification and clustering, implement a sub class popularity prediction method, and construct user profile according to our actual situation. We had designed several experiments compared to the state-of-the-art approaches on a real world dataset, and the experimental results demonstrate that our system significantly improves the accuracy and diversity in mass text data.

    The authors compared local TV news with national TV news in terms of cancer coverage using a nationally representative sample of local nightly TV and national network TV (i.e., ABC, CBS, NBC, and CNN) cancer news stories that aired during 2002 and 2003. Compared with national TV news, local TV cancer stories were (a) much shorter in length, (b) less likely to report on cancer prevention (i.e., preventive behaviors and screening tests), and (c) less likely to reference national organizations (i.e., National Cancer Institute, American Cancer Society, National Institutes of Health, Centers for Disease Control and Prevention, Food and Drug Administration) that have made clear recommendations about ways to prevent cancer. The implications of these findings for health communication research and cancer education were discussed.

The proposed model is used in a Digital Archives Project as a means of value adding and knowledge aggregation. We first compared and analyzed multiple wiki engines to select the best system for our research purpose. We chose Taiwanese Baseball News Digital Archive as the base of the research project and the wiki collaboration system as the platform. In order to improve and enhance the quality of digital content, we took the approach of applying techniques of knowledge organization, such as classification, indexing, thesaurus, and controlled vocabularies, so that value and knowledge can be added and aggregated. As the data and community grow, interaction of community members becomes crucial. Therefore, we discussed ways to encourage group interaction and participation from the operational and managerial point of view.

    2012-06-01

    The purpose of this study was to explore how obesity was covered in television news in China, including the trends over time and the characteristics of obesity-related news. The frame analysis was adopted to assess the content of obesity-related news broadcasted in China Central Television (CCTV) from 1982 to 2009. To investigate the characteristics of the news, the obesity-related news was divided into subgroups according to populations concerned, as well as the period in which the news was broadcasted. The differences between subgroups were examined. A total of 1 599 pieces of news reported obesity, in which 1 278 pieces (79.92%) aired in "wealthy" period (2006-2009). More news was concerned with adults (1 134, 70.92%). "Individual behavior" dominated most of the cause frames (389, 24.33%), solution frames (522, 32.65%), and responsibility frames (860, 53.78%). There was more news mentioning individual factors in news aired in "wealthy" period and news concerning children. The coverage of social-structure causes was higher in news concerning children, while the coverage of social-structure solutions was higher in news concerning children and news aired in "wealthy" period. Although the coverage of obesity was modest, it showed an incremental trend as the economy grew. Obesity was mostly depicted as an individual problem in terms of responsibility, causes and solutions.

    This paper maps the flows of data to and from third-party actors when users access content in mobile news apps. This way, it analyzes the strategic networks of collaboration and data exchange that news organizations engage in in the digital economy, expanding the traditional two-sided model...... of media economics (centered around sales to audiences and advertisers) to also account for what happens “behind the curtain”. Research already shows that the trade with data constitutes a central component of web-based business models (Evens & Van Damme, 2016; Gerlitz & Helmond, 2013; Lindskow, 2016......), but no systematic scrutiny of the same phenomenon exists with regards to mobile news use even though the use of mobile platforms for news accessing increases these years (Newman, Levy, & Nielsen, 2015).

Three studies investigate whether people prefer to pass along pieces of bad news or good news that are equated for "surprisingness." People typically prefer to pass along central rather than extreme information (i.e., news that is less surprising rather than more surprising). However, when confronted with extreme information, the results support a preference for congruence, that is, people prefer to pass along news that is congruent with the emotional valence of the domain in question. This means that in emotionally negative domains, contrary to some theoretical predictions, people are willing to pass along bad news even when it is exaggeratedly bad. At the same time, however, people transmit exaggeratedly good news in emotionally positive domains. The general discussion indicates how these results may inform research on word of mouth for consumer products and social relations in organizations.

    Willmes, C.

    2017-12-01

    In the frame of the Collaborative Research Centre 806 (CRC 806) an interdisciplinary research project, that needs to manage data, information and knowledge from heterogeneous domains, such as archeology, cultural sciences, and the geosciences, a collaborative internal knowledge base system was developed. The system is based on the open source MediaWiki software, that is well known as the software that enables Wikipedia, for its facilitation of a web based collaborative knowledge and information management platform. This software is additionally enhanced with the Semantic MediaWiki (SMW) extension, that allows to store and manage structural data within the Wiki platform, as well as it facilitates complex query and API interfaces to the structured data stored in the SMW data base. Using an additional open source software called mobo, it is possible to improve the data model development process, as well as automated data imports, from small spreadsheets to large relational databases. Mobo is a command line tool that helps building and deploying SMW structure in an agile, Schema-Driven Development way, and allows to manage and collaboratively develop the data model formalizations, that are formalized in JSON-Schema format, using version control systems like git. The combination of a well equipped collaborative web platform facilitated by Mediawiki, the possibility to store and query structured data in this collaborative database provided by SMW, as well as the possibility for automated data import and data model development enabled by mobo, result in a powerful but flexible system to build and develop a collaborative knowledge base system. Furthermore, SMW allows the application of Semantic Web technology, the structured data can be exported into RDF, thus it is possible to set a triple-store including a SPARQL endpoint on top of the database. The JSON-Schema based data models, can be enhanced into JSON-LD, to facilitate and profit from the possibilities of Linked Data

    This paper presents an emotion mining system, which assigns emoticons to newspaper articles into a pre-defined emotion category based on the underlying emotion in the news. Next, the system makes recommendation to the reader by tagging the news headline with the respective emoticons. Users are then able to decide whether to read the news based on the emoticons provided. The system also provides a filter for the users to choose the category of news to read following the emoticons.

    Full Text Available Mass media through the Internet is a powerful means of disseminating medical research. We aimed to determine whether and how the interpretation of research results is misrepresented by the use of "spin" in the health section of Google News. Spin was defined as specific way of reporting, from whatever motive (intentional or unintentional, to emphasize that the beneficial effect of the intervention is greater than that shown by the results.We conducted a cross-sectional study of news highlighted in the health section of US, UK and Canada editions of Google News between July 2013 and January 2014. We searched for news items for 3 days a week (i.e., Monday, Wednesday, and Friday during 6 months and selected a sample of 130 news items reporting a scientific article evaluating the effect of an intervention on human health.In total, 78% of the news did not provide a full reference or electronic link to the scientific article. We found at least one spin in 114 (88% news items and 18 different types of spin in news. These spin were mainly related to misleading reporting (59% such as not reporting adverse events that were reported in the scientific article (25%, misleading interpretation (69% such as claiming a causal effect despite non-randomized study design (49% and overgeneralization/misleading extrapolation (41% of the results such as extrapolating a beneficial effect from an animal study to humans (21%. We also identified some new types of spin such as highlighting a single patient experience for the success of a new treatment instead of focusing on the group results.Interpretation of research results was frequently misrepresented in the health section of Google News. However, we do not know whether these spin were from the scientific articles themselves or added in the news.

    Full Text Available In the past few years considerable demand for business oriented multimedia information systems has developed. A multimedia information system is one that can create, import, integrate, store, retrieve, edit, and delete two or more types of media materials in digital form, such as audio, image, full-motion video, and text information. Multimedia information systems play a central role in many business activities. They represent a very special class complex computing systems. This paper surveys a special type of multimedia information systems: multimedia news systems. Multimedia news systems deal with architectures to manage complex multimedia news databases, online presentation and distribution services or the integration of several existing services to meta-services using intelligent news retrieval engines. The leading presentation platform in multimedia news presentation is news networks providing television services and Internet content distribution. The primary focus is on advanced multimedia news systems infrastructure, document standards, application architecture and principles for multimedia news on the Web that suggest long-term trends in this increasingly important area.

  19. Masculinity discourse on media text: A critical review about news about violence on online news portals

    Directory of Open Access Journals (Sweden)

    Daniel Susilo

    2017-12-01

    Full Text Available Media as a medium plays a significant role in strengthening gender concept in society. Female’s sexualities are viewed as an object of judgement for the media. For the sake of men readers’ satisfaction, media justifies itself in its attempts to exploit women sexuality. Masculine’s way of thinking has been perpetuated in reports about women. Masculine men are considered empowering female’s bodies. Violence acts are considered as the form of masculine domination over feminine beings. This research aims to dismantle how media construct their texts on masculine discourses on online news portals. Online news portals are required to be swift in uploading news and using their acquired resources; thus, they perpetuate this masculine discourse. Critical discourse analysis of Van Dick was employed to unravel masculine discourse structures on media texts at the largest news portals in Indonesia, Alexa.com; and Tribunnews.com; which belong to a corporate media, Kompas Gramedia. The findings of this research state that online news portals and their acquired resources strengthen violence labelling as a part of masculine domination over feminine beings.

    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.

    The manner in which healthcare professionals deliver bad news affects the way it is received, interpreted, understood, and dealt with. Despite the fact that clinicians are responsible for breaking bad news, it has been shown that they lack skills necessary to perform this task. The purpose of this study was to explore Iranian mothers' experiences to receive bad news about their children cancer and to summarize suggestions for improving delivering bad news by healthcare providers. A qualitative approach using content analysis was adopted. Semi-structured interviews were conducted with 14 mothers from two pediatric hospitals in Iran. Five major categories emerged from the data analysis, including dumping information, shock and upset, emotional work, burden of delivering bad news to the family members, and a room for multidisciplinary approach. Effective communication of healthcare team with mothers is required during breaking bad news. Using multidisciplinary approaches to prevent harmful reactions and providing appropriate support are recommended.

  5. Women in Television News: Analysis of Primetime News on HTV, RTL and Nova TV

    Directory of Open Access Journals (Sweden)

    Svjetlana Knežević

    2011-12-01

    Full Text Available This article assesses the particularly low level of women represented on national primetime television newscasts in Croatia. In doing so, it presents the results of a content analysis covering a random,stratified sample of HTV, Nova TV, and RTL primetime news broadcasts over the years 2009 and 2010. According to these results, women are significantly underrepresented as main characters, experts, or even persons relevant to news stories concerning issues or problems. In particular, the results are most apparent on the primetime newscast Dnevnik, broadcasted daily on Croatia’s main public television station. Ideally, this news broadcast should rank among the best in terms of gender equality, given the principles of equality stipulated throughout Croatian law (and especially where it concerns programming legislation. Concerning the analyzed content, when women serve as the main characters in a news story, their emotional response to an issue appears to be almost obligatory. Further, women are often portrayed as victims, or as a figure to galvanize a rather black and white response, i.e. they are to be praised or blamed. Adding to this gender discrepancy, statistics show that more women than men have earned BA and MA degrees, which not only highlights the unbalanced representation of women on television news, but also distorts the actual level of female participation in society, particularly where it regards sociopolitical fields.

    Recent research has demonstrated that the media presentation of childbirth is highly medicalized, often portraying birth as risky and dramatic. Media representation of breech presentation and birth is unexplored in this context. This study aimed to explore the content and tone of news media reports relating to breech presentation and breech birth. Google alerts were created using the terms breech and breech birth in online English-language news sites over a 3-year period from January 1, 2013, to December 31, 2015. Alerts were received daily and filed for analysis, and data were analyzed to generate themes. A total of 138 web-based news reports were gathered from 9 countries. Five themes that arose from the data included the problem of breech presentation, the high drama of vaginal breech birth, the safe option of cesarean birth versus dangers of vaginal breech birth, the defiant mother versus the saintly mother, and vaginal breech birth and medical misadventure. Media reports in this study predominantly demonstrated negative views toward breech presentation and vaginal breech birth. Cesarean birth was portrayed as the safe option for breech birth, while vaginal breech birth was associated with poor outcomes. Media presentations may impact decision making about mode of birth for pregnant women with a breech fetus. Health care providers can play an important role in balancing the media depiction of planned vaginal breech birth by providing nonjudgmental, evidence-based information to such women to facilitate informed decision making for birth. © 2017 by the American College of Nurse-Midwives.

    Upon admission to an intensive care unit (ICU), all patients should discuss their goals of care and express their wishes concerning life-sustaining interventions (e.g., cardiopulmonary resuscitation (CPR)). Without such discussions, interventions that prolong life at the cost of decreasing its quality may be used without appropriate guidance from patients. To adapt an existing decision aid about CPR to create a wiki-based decision aid individually adapted to each patient's risk factors; and to document the use of a wiki platform for this purpose. We conducted three weeks of ethnographic observation in our ICU to observe intensivists and patients discussing goals of care and to identify their needs regarding decision making. We interviewed intensivists individually. Then we conducted three rounds of rapid prototyping involving 15 patients and 11 health professionals. We recorded and analyzed all discussions, interviews and comments, and collected sociodemographic data. Using a wiki, a website that allows multiple users to contribute or edit content, we adapted the decision aid accordingly and added the Good Outcome Following Attempted Resuscitation (GO-FAR) prediction rule calculator. We added discussion of invasive mechanical ventilation. The final decision aid comprises values clarification, risks and benefits of CPR and invasive mechanical ventilation, statistics about CPR, and a synthesis section.

    Narayanan, Vijayakumar; Bista, Bibek; Koshy, Cheriyan

    2010-05-01

    Information that drastically alters the life world of the patient is termed as bad news. Conveying bad news is a skilled communication, and not at all easy. The amount of truth to be disclosed is subjective. A properly structured and well-orchestrated communication has a positive therapeutic effect. This is a process of negotiation between patient and physician, but physicians often find it difficult due to many reasons. They feel incompetent and are afraid of unleashing a negative reaction from the patient or their relatives. The physician is reminded of his or her own vulnerability to terminal illness, and find themselves powerless over emotional distress. Lack of sufficient training in breaking bad news is a handicap to most physicians and health care workers. Adherence to the principles of client-centered counseling is helpful in attaining this skill. Fundamental insight of the patient is exploited and the bad news is delivered in a structured manner, because the patient is the one who knows what is hurting him most and he is the one who knows how to move forward. Six-step SPIKES protocol is widely used for breaking bad news. In this paper, we put forward another six-step protocol, the BREAKS protocol as a systematic and easy communication strategy for breaking bad news. Development of competence in dealing with difficult situations has positive therapeutic outcome and is a professionally satisfying one.

    Full Text Available with release of a huge amount of news on the Internet and the trend of users to Web-based news services.it is necessary to have a recommendation system. To grab attentions to news, news services use a number of criteria that called news values and user location is an important factor for it. In this paper, LONEF is proposed as a tow stage recommendation system. In first stage news are ranked by user’s locations and in second stage news are recommended by location Preferences, recency, Trustworthiness, groups priorities and popularity. To reduce ambiguity these properties is used tow Mamdani fuzzy interference and case-based decision systems. In Mamdani fuzzy interference system, it is tried to increase the system speed by optimizing selection of rules and membership functions and because of ambiguous feedback implementation, a decision making system is used to enable better simulation of user’s activities. Performance of our proposed approach is demonstrated in the experiments on different news groups.

    We investigated the differential diffusion of all of the verified true and false news stories distributed on Twitter from 2006 to 2017. The data comprise ~126,000 stories tweeted by ~3 million people more than 4.5 million times. We classified news as true or false using information from six independent fact-checking organizations that exhibited 95 to 98% agreement on the classifications. Falsehood diffused significantly farther, faster, deeper, and more broadly than the truth in all categories of information, and the effects were more pronounced for false political news than for false news about terrorism, natural disasters, science, urban legends, or financial information. We found that false news was more novel than true news, which suggests that people were more likely to share novel information. Whereas false stories inspired fear, disgust, and surprise in replies, true stories inspired anticipation, sadness, joy, and trust. Contrary to conventional wisdom, robots accelerated the spread of true and false news at the same rate, implying that false news spreads more than the truth because humans, not robots, are more likely to spread it.

  9. Breaking bad news: issues relating to nursing practice.

    Science.gov (United States)

    Warnock, Clare

    2014-07-15

    The breaking of bad news was traditionally regarded to be the time when a doctor and nurse sat down with a patient and family members to provide information about, for example, a life-limiting diagnosis or a poor prognosis. However, breaking bad news is now generally accepted as a process, not a one-off event, and is considered to refer to any bad, sad or difficult information that alters patients' perceptions of their present and future. Nurses have an important role in the process of providing information and helping patients prepare for, receive, understand and cope with the bad news they have been given. This article aims to help nurses understand the process of breaking bad news and discuss the challenges and difficulties that nurses can face when they are involved with patients who have been given bad news. It also provides guidance with regard to preparing for breaking bad news, giving difficult information, responding to possible reactions, and supporting patients and their relatives after they have received bad news.

    Full Text Available The last presidential elections in the United States of America (2016 have brought to the international public opinion’ s attention the phenomenon of “fake news”. Though it isn’t a new phenomenon, the spread of fake information for manipulating and misinforming the masses has existed in all historical periods. This time the phenomenon was noticed because of the number of fake news and, especially because of their impact, starting the discussion whether the victory of Donald Trump happened because of fake news and raising the question whether this phenomenon is a danger to democracy. An important reaction came also from the part of technology companies, of tech giants, Google and Facebook especially, which want the implementation of the phenomenon. Misinformation with public speech under the form of fake news brings to discussion the responsibility in the online space, but also the protection of people against this phenomenon.

    2017-01-01

    News coverage of Islamic extremism is reigniting debates about the media's role in promoting prejudice toward Muslims. Psychological theories of media-induced prejudice date to the 1950's, and find support from controlled experiments. However, national-scale studies of media effects on Muslim prejudice are lacking. Orthogonal research investigating media-induced prejudice toward immigrants has failed to establish any link. Moreover, it has been found that people interpret the news in ways that confirm pre-existing attitudes, suggesting that media induced Muslim prejudice in liberal democracies is unlikely. Here, we test the association between news exposure and anti-Muslim prejudice in a diverse national sample from one of the world's most tolerant societies, where media effects are least likely to hold (N = 16,584, New Zealand). In support of media-induced Islamophobia, results show that greater news exposure is associated with both increased anger and reduced warmth toward Muslims. Additionally, the relationship between media exposure and anti-Muslim prejudice does not reliably vary with political ideology, supporting claims that it is widespread representations of Muslims in the news, rather than partisan media biases, that drives anti-Muslim prejudice.

    2016-04-01

    Crowdsourcing is a new approach for solving data processing problems for which conventional methods appear to be inaccurate, expensive, or time-consuming. Nowadays, the development of new crowdsourcing techniques is mostly motivated by so called Big Data problems, including problems of assessment and clustering for large datasets obtained in aerospace imaging, remote sensing, and even in social network analysis. By involving volunteers from all over the world, the Geo-Wiki project tackles problems of environmental monitoring with applications to flood resilience, biomass data analysis and classification of land cover. For example, the Cropland Capture Game, which is a gamified version of Geo-Wiki, was developed to aid in the mapping of cultivated land, and was used to gather 4.5 million image classifications from the Earth's surface. More recently, the Picture Pile game, which is a more generalized version of Cropland Capture, aims to identify tree loss over time from pairs of very high resolution satellite images. Despite recent progress in image analysis, the solution to these problems is hard to automate since human experts still outperform the majority of machine learning algorithms and artificial systems in this field on certain image recognition tasks. The replacement of rare and expensive experts by a team of distributed volunteers seems to be promising, but this approach leads to challenging questions such as: how can individual opinions be aggregated optimally, how can confidence bounds be obtained, and how can the unreliability of volunteers be dealt with? In this paper, on the basis of several known machine learning techniques, we propose a technical approach to improve the overall performance of the majority voting decision rule used in the Cropland Capture Game. The proposed approach increases the estimated consistency with expert opinion from 77% to 86%.

    Full Text Available [english] Problem: The new study regulation for medical licensing in Germany has caused significant reform of the medical curricula. At Munich University (LMU, the Medical Curriculum Munich (MeCuM was introduced in 2004. More individual responsibility of the students regarding their academic goals as well as a problem-oriented thought process are essential features of the new curriculum. Through our project, an open web based platform for the design of curriculum-specific teaching and study material has become accessible to students and faculty of the MeCuM. Methods: Students created an online library in harmony with the curricular structure of the MeCuM. The technical implementation was carried out with the MediaWiki-Open-Source software. Contents can be edited from all students or faculty of the MeCuM in an anonymous or personalized manner. An online questionnaire was carried out to evaluate the project. Results: Our online library as a wiki is the first solution of this kind in medical education in Germany. The concept was implemented without technical difficulties and is linked to the official websites of LMU Munich. The website’s contents were visited 417,808 times from December 2005 through June 2007. Online-based evaluation showed that the project is positively recognized, and students are motivated to contribute actively. Discussion: The project closely reflects the academic curriculum of the MeCuM and creates additional opportunities for interaction between students and teachers. The design as an open source project allows easy handling as well as frequent control and ability to update the contents, but integrity and accuracy of the data content require further effort. Additional evaluation will be essential for improvements. The integration of faculty as reviewers and tutors is planned. Sustainability of the project is dependent upon continued student leadership. The concept of the project has been transferred to another medical

Por este motivo, que una herramienta como las wikis, que permita trabajar fuera del aula y con la cual el estudiante puede realizar trabajos individuales y en grupo, conectado y en contacto con el resto de sus compañeros y profesores, resulta especialmente útil. Mientras que la sencillez de estas herramientas permite al docente diseñar actividades atractivas y útiles con un esfuerzo y conocimientos tecnológicos relativamente mínimos, para los estudiantes supone una gran oportunidad para aprender a trabajar con las TIC y de manera grupal y colaborativa.

  16. Breaking the news or fueling the epidemic? Temporal association between news media report volume and opioid-related mortality.

    Directory of Open Access Journals (Sweden)

    Nabarun Dasgupta

    2009-11-01

    Full Text Available Historical studies of news media have suggested an association between reporting and increased drug abuse. Period effects for substance use have been documented for different classes of legal and illicit substances, with the suspicion that media publicity may have played major roles in their emergence. Previous analyses have drawn primarily from qualitative evidence; the temporal relationship between media reporting volume and adverse health consequences has not been quantified nationally. We set out to explore whether we could find a quantitative relationship between media reports about prescription opioid abuse and overdose mortality associated with these drugs. We assessed whether increases in news media reports occurred before or after increases in overdose deaths.Our ecological study compared a monthly time series of unintentional poisoning deaths involving short-acting prescription opioid substances, from 1999 to 2005 using multiple cause-of-death data published by the National Center for Health Statistics, to monthly counts of English-language news articles mentioning generic and branded names of prescription opioids obtained from Google News Archives from 1999 to 2005. We estimated the association between media volume and mortality rates by time-lagged regression analyses. There were 24,272 articles and 30,916 deaths involving prescription opioids during the seven-year study period. Nationally, the number of articles mentioning prescription opioids increased dramatically starting in early 2001, following prominent coverage about the nonmedical use of OxyContin. We found a significant association between news reports and deaths, with media reporting preceding fatal opioid poisonings by two to six months and explaining 88% (p<0.0001, df 78 of the variation in mortality.While availability, structural, and individual predispositions are key factors influencing substance use, news reporting may enhance the popularity of psychoactive

    Jaffery, Jonathan B; Jacobson, Lynn M; Goldstein, Kenneth M; Pribble, James M

    2006-12-01

    Local television is the primary news source for the majority of Americans. This study aims to describe how local news reports on kidney disease. Using our searchable database of health-related late local news segments from 2002, we identified stories with the key words kidney, hypertension, blood pressure, or diabetes. This database is a representative sample of the late local news on 122 stations in the 50 largest US media markets, comprising 60% of the population. The content of each identified story was reviewed to determine whether it mentioned: (1) chronic kidney disease (CKD), (2) screening for kidney disease, or (3) kidney disease as a potential complication (for blood pressure- or diabetes-related stories). Only 2 of 1,799 database news stories (0.11%) included "kidney" as a summary key word; neither referred to CKD, screening, or complications of other diseases. Of 19 stories about hypertension or blood pressure (1.06% of all stories) and the 14 stories about diabetes (0.78% of all stories), none mentioned these criteria. Despite efforts to increase public awareness of and screening for CKD, local television news (the most important news source for a majority of Americans) did little to help achieve these goals. Further work will be needed to confirm whether this paucity of coverage varies over time and determine why so little attention is given to CKD. Educating physicians and public relations personnel who advocate for kidney disease about journalists' needs may be an important step to help advance public awareness of CKD.

  1. A Functional Conceptualization of Understanding Science in the News

    Science.gov (United States)

    Anderson, Megan M.

    The idea that the public should have the capacity for understanding science in the news has been embraced by scientists, educators, and policymakers alike. An oft-cited goal of contemporary science education, in fact, is to enhance students' understanding of science in the news. But what exactly does it mean to understand science in the news? Surprisingly few have asked this question, or considered the significance of its answer. This dissertation steps away from issues of science teaching and learning to examine the nature of understanding science in the news itself. My work consolidates past scholarship from the multiple fields concerned with the relationship between science and society to produce a theoretical model of understanding science in the news as a complex, multidimensional process that involves an understanding of science as well as journalism. This thesis begins by exploring the relationship between the understanding implicit in understanding science in the news and understanding science. Many assume these two ways of knowing are one in the same. To rebut this assumption, I examine the types of knowledge necessary for understanding science and understanding science in the news. I then use the literature devoted to scientific literacy to show how past research has imagined the knowledge necessary to understand science in the news. Next, I argue that one of the principle difficulties with these conceptualizations is that they define science in the news in essentially the same terms as science. They also, I suggest, oversimplify how and why public interacts with science in the news. This dissertation concludes with a proposal for one way we might think about understanding science in the news on its own terms rather than those of understanding science. This dissertation attempts to connect two fields of research that rarely intersect, despite their multiple common interests: science education and mass communication. It considers the notion of

    Full Text Available Due to the technological developments, people are able to quickly reach the information and the news about destinations where they have planned to go on their holidays. Online news websites are important and reliable tools which deliver up-to-date information about a destination to broad masses. It is indisputable that the media is a significant influence on public awareness, tourist purchase decision, destination image and tourist behavior. A tourist who chooses a holiday destination decides among countless destinations according to the information he receives from various sources. Therefore, in this study, the news in the two foreign online news sites are interpreted according to the touristic arrival statistics from the Ministry of Culture and Tourism. The two countries to be included in the study, Germany and England, were selected among the countries that sent the most tourists to Turkey. In these countries, news web sites with the highest number of daily visitors were determined and the news related to Turkey in the 7 years period between 2010 and 2016 were analyzed by content analysis.

    Full Text Available Las instituciones de educación superior están sufriendo un proceso de reconversión buscando su adaptación a las características del Espacio Europeo de Educación Superior. Uno de los cambios más importantes, a los que debe hacer frente su profesorado, consiste en una reorganización metodológica diferente de sus clases. Por ello, es necesario pensar en nuevas fórmulas en la formación del profesorado. Como resultado de esta necesidad, decidimos organizar la asignatura de Nuevas Tecnologías Aplicadas a la Educación, de la Facultad de Educación de Valladolid, empleando una metodología activa, el IBL, apoyada en una plataforma Wiki, proponiendo a nuestro alumnado una serie de actividades que debían realizar colaborativamente. En este trabajo, presentamos una de esas actividades, la elaboración de una Wiki- WebQuest. A partir de la descripción de esta actividad, pretendemos mostrar algunas luces y sombras sobre su puesta en práctica (la versatilidad y flexibilidad de la plataforma, la posibilidad de colaboración entre la universidad y la escuela, la falta de adaptación de algunos contenidos al nivel curricular del curso concreto, la falta de asesoramiento del profesorado al alumnado de primaria sobre el uso de estas nuevas herramientas, etc. Esta actividad fue desarrollada a partir de la colaboración con contextos educativos reales (dos centros de primaria, sirviendo de caso de estudio para diseñar una Wiki-WebQuest.

  9. For Video Games, Bad News Is Good News: News Reporting of Violent Video Game Studies.

    Copenhaver, Allen; Mitrofan, Oana; Ferguson, Christopher J

    2017-12-01

    News coverage of video game violence studies has been critiqued for focusing mainly on studies supporting negative effects and failing to report studies that did not find evidence for such effects. These concerns were tested in a sample of 68 published studies using child and adolescent samples. Contrary to our hypotheses, study effect size was not a predictor of either newspaper coverage or publication in journals with a high-impact factor. However, a relationship between poorer study quality and newspaper coverage approached significance. High-impact journals were not found to publish studies with higher quality. Poorer quality studies, which tended to highlight negative findings, also received more citations in scholarly sources. Our findings suggest that negative effects of violent video games exposure in children and adolescents, rather than large effect size or high methodological quality, increase the likelihood of a study being cited in other academic publications and subsequently receiving news media coverage.

  10. Breaking the news or fueling the epidemic? Temporal association between news media report volume and opioid-related mortality.

    Historical studies of news media have suggested an association between reporting and increased drug abuse. Period effects for substance use have been documented for different classes of legal and illicit substances, with the suspicion that media publicity may have played major roles in their emergence. Previous analyses have drawn primarily from qualitative evidence; the temporal relationship between media reporting volume and adverse health consequences has not been quantified nationally. We set out to explore whether we could find a quantitative relationship between media reports about prescription opioid abuse and overdose mortality associated with these drugs. We assessed whether increases in news media reports occurred before or after increases in overdose deaths. Our ecological study compared a monthly time series of unintentional poisoning deaths involving short-acting prescription opioid substances, from 1999 to 2005 using multiple cause-of-death data published by the National Center for Health Statistics, to monthly counts of English-language news articles mentioning generic and branded names of prescription opioids obtained from Google News Archives from 1999 to 2005. We estimated the association between media volume and mortality rates by time-lagged regression analyses. There were 24,272 articles and 30,916 deaths involving prescription opioids during the seven-year study period. Nationally, the number of articles mentioning prescription opioids increased dramatically starting in early 2001, following prominent coverage about the nonmedical use of OxyContin. We found a significant association between news reports and deaths, with media reporting preceding fatal opioid poisonings by two to six months and explaining 88% (pnews reporting may enhance the popularity of psychoactive substances. Albeit ecological in nature, our finding suggests the need for further evaluation of the influence of news media on health. Reporting on prescription opioids conforms

    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.

  20. Obesity in the news: directions for future research.

    Science.gov (United States)

    Atanasova, D; Koteyko, N; Gunter, B

    2012-06-01

    Obesity attracts large volumes of news coverage. This in turn has spawned academic studies investigating how news framing may affect views about causes of and solutions to obesity. We use key studies to demonstrate that although existing research has made valuable discoveries about how obesity is defined in various media outlets, some methodological and theoretical questions remain unaddressed. We argue that extant research has focused on one dimension of analysis--the problematization of obesity in news stories--precluding insights into the entire process of obesity communication. Drawing on framing and media studies research, we propose a multidimensional approach to shed more light on factors affecting the production of obesity news stories by journalists and how they may be received by audience members. Ways of moving research into this multidimensional direction are proposed, including analysis of journalistic news values, political leaning and style of media outlets, emotion-eliciting language, readers' comments and obesity-related news visuals. Knowledge resulting from the exploration of these dimensions of the issue of obesity can be used to improve strategies to inform and engage audience members. © 2012 The Authors. obesity reviews © 2012 International Association for the Study of Obesity.

  4. Breaking bad news among cancer physicians

    Directory of Open Access Journals (Sweden)

    Sami Ayed Alshammary

    2017-01-01

    Full Text Available Background: Breaking bad news to patients with cancer diagnosis is not an easy task for physicians. The diagnosis must be explicitly stated and understood, and prognosis must be well-discussed in the most gentle and comfortable manner. It is important that the disclosure is performed in a way that patients will not lose all hope and get very depressed, leading them to undergo an abrupt change of their outlook in life. Objective: The aim of this study was to explore the physicians' perceptions and perspectives of breaking bad news to cancer patients. Methods: A cross-sectional survey of all comprehensive cancer centre physicians currently working in a university teaching hospital in the Middle East was conducted from August to September 2016. Results: Sixty-eight percent responded to the survey. Eighty-four percent were comfortable with breaking bad news, and 70% had training in breaking bad news. Eighty-six percent of responders stated that patients should be told about their cancer. Almost 30% of the respondents stated that they would still disclose the diagnosis to patients even if it would be against the preference of the relatives. Nearly 61% said that they would only tell the details to the patients if asked while 67% of them disagreed that patients should be told about the diagnoses only if the relatives consent. About 51% of physicians wanted to discuss the bad news with the family members and patient together, whereas 24% stated that the patient alone should be involved in the discussion. Conclusion: Physicians face a dilemma when families do not wish the patient to know the cancer diagnosis and this highlights the necessity of taking into consideration the social circumstances in healthcare. When taking these into considerations, curriculum in the medical school must, therefore, be updated and must integrate the acquisition of skills in breaking bad news early in training.

  5. Tipping news in information accumulation system

    Science.gov (United States)

    Shin, J. K.

    2010-05-01

    As a continuous opinion dynamics model, the information accumulation system (IAS) includes three basic mechanisms of the news, the inheritance and the diffusion as contributing to the information accumulation process of a system. A system is composed of agents who diffuse information through internal interaction, while each of them has incomplete memory or inheritance rate. The news comes from external sources of information, such as mass media. Previously the model IAS was studied only for the small news problems. In this study, a tipping news problem is considered. A key question of the problem is: what is the minimum strength of advertisement that can tip the minority opinion to a majority one? Dynamics of the IAS is briefly revisited with a special interest on nonlinear behavior of the model. In particular, it is shown that a discrete map of the IAS for a single color problem can be transformed into a logistic map, from which the dynamics of the IAS can be better understood. To show the applicability of the IAS model, the result is applied to explain the concept of the critical population size, which claims that there is a minimum population size for a social knowledge system to be continuously inherited without being lost. And critical size of the tipping news is found analytically in terms of IAS parameters. Some of the key results from the present study are compared in detail with the results from the Brownian particle model, which is believed to be the most similar model to the IAS. The concept of tipping news is used to show that a traditional society can tip at an exceptionally low inter-community exposure. Finally, the result was applied to the language competition problem.

    Full Text Available This work shows the development of audiovisual webjournalism on the Brazilian Internet. This paper, based on the analysis of UOL News on UOL TV – pioneer format on commercial web television - and of UERJ Online TV – first on-line university television in Brazil - investigates the changes in the gathering, production and dissemination processes of audiovisual news when it starts to be transmitted through the web. Reflections of authors such as Herreros (2003, Manovich (2001 and Gosciola (2003 are used to discuss the construction of audiovisual narrative on the web. To comprehend the current changes in today’s webjournalism, we draw on the concepts developed by Fidler (1997; Bolter and Grusin (1998; Machado (2000; Mattos (2002 and Palacios (2003. We may conclude that the organization of narrative elements in cyberspace makes for the efficiency of journalistic messages, while establishing the basis of a particular language for audiovisual news on the Internet.

  7. ′BREAKS′ protocol for breaking bad news

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Information that drastically alters the life world of the patient is termed as bad news. Conveying bad news is a skilled communication, and not at all easy. The amount of truth to be disclosed is subjective. A properly structured and well-orchestrated communication has a positive therapeutic effect. This is a process of negotiation between patient and physician, but physicians often find it difficult due to many reasons. They feel incompetent and are afraid of unleashing a negative reaction from the patient or their relatives. The physician is reminded of his or her own vulnerability to terminal illness, and find themselves powerless over emotional distress. Lack of sufficient training in breaking bad news is a handicap to most physicians and health care workers. Adherence to the principles of client-centered counseling is helpful in attaining this skill. Fundamental insight of the patient is exploited and the bad news is delivered in a structured manner, because the patient is the one who knows what is hurting him most and he is the one who knows how to move forward. Six-step SPIKES protocol is widely used for breaking bad news. In this paper, we put forward another six-step protocol, the BREAKS protocol as a systematic and easy communication strategy for breaking bad news. Development of competence in dealing with difficult situations has positive therapeutic outcome and is a professionally satisfying one.

  10. Automatic Story Segmentation for TV News Video Using Multiple Modalities

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available While video content is often stored in rather large files or broadcasted in continuous streams, users are often interested in retrieving only a particular passage on a topic of interest to them. It is, therefore, necessary to split video documents or streams into shorter segments corresponding to appropriate retrieval units. We propose here a method for the automatic segmentation of TV news videos into stories. A-multiple-descriptor based segmentation approach is proposed. The selected multimodal features are complementary and give good insights about story boundaries. Once extracted, these features are expanded with a local temporal context and combined by an early fusion process. The story boundaries are then predicted using machine learning techniques. We investigate the system by experiments conducted using TRECVID 2003 data and protocol of the story boundary detection task, and we show that the proposed approach outperforms the state-of-the-art methods while requiring a very small amount of manual annotation.

    Full Text Available This paper reports on the effects of using wiki-based process writing in Singapore’s Chinese as a Second Language (CSL scenarios. A group of 32 Secondary 1 (Seventh Grade students (“Students” received various forms of online scaffolding at different steps of the writing process over two years. A whole set of teaching materials on 45 writing skills was developed and uploaded to the Wiki platform through five recursive cycles. In each cycle, the students were encouraged to apply skills they learned via Wiki platform in their writing and afterwards work as a team in the platform to peer-review each other’s first draft. With feedback received from peer revision, students proceeded to edit their first draft, focusing on the content of narratives and the appropriateness on their use of micro writing skills. The scaffolding decreased as the project progressed. Students’ pre-, mid- and post-writing tests were marked and compared. The authors analyzed the impact that the feedback in the process had towards the students’ overall writing performance. It was discovered that students' quality of written products was improved in general. It was also discovered that students benefited the most from giving remarks to their peers’ writing. The revision patterns of high, medium and low language ability students were also compared. It was found that the higher the language ability of the students, the more concerned they were with macro level for their revisions. ICT-mediated process writing has not garnered much attention in the field of CSL. The study hopes to contribute to the literature of ICTmediated writing instruction in the field of CSL.

    2014-10-01

    Breaking bad news is a complex and frequent clinical task for physicians working in oncology. It can have a negative impact on patients and their relatives who are often present during breaking bad news consultations. Many factors influence how the delivery of bad news will be experienced especially the communication skills used by physicians. A three-phase process (post-delivery phase, delivery phase, pre-delivery phase) has been developed to help physician to handle this task more effectively. Communication skills and specific breaking bad news training programs are both necessary and effective. A recent study conducted in Belgium has shown their impact on the time allocated to each of the three phases of this process, on the communication skills used, on the inclusion of the relative in the consultation and on physicians' physiological arousal. These results underscore the importance of promoting intensive communication skills and breaking bad news training programs for health care professionals.

    2013-01-01

    Full Text Available A documentação de um Sistema de Gestão da Qualidade padrão ISO 9001 é muitas vezes vista como uma fonte de burocracia nas organizações. Este artigo descreve o WikiQMS como uma alternativa para a informatização da documentação de tal sistema. O método científico foi aplicado para o desenvolvimento do sistema. O protótipo foi desenvolvido a partir de um software wiki, com base nos requisitos da ISO 9001 levantados na literatura e também pela avaliação de um painel de especialistas. O experimento de campo em uma empresa júnior permitiu validar o sistema em uma situação real de implantação da documentação do Sistema de Gestão da Qualidade. O protótipo atende adequadamente aos requisitos mínimos de implantação e gestão da documentação do Sistema de Gestão da Qualidade padrão ISO 9001. Além disso, o WikiQMS apresenta as vantagens de uma solução da Web 2.0 para a questão da edição colaborativa, autoria coletiva, acessibilidade e usabilidade.

  20. Estimation of Cross-Lingual News Similarities Using Text-Mining Methods

    2018-01-01

    Full Text Available In this research, two estimation algorithms for extracting cross-lingual news pairs based on machine learning from financial news articles have been proposed. Every second, innumerable text data, including all kinds news, reports, messages, reviews, comments, and tweets are generated on the Internet, and these are written not only in English but also in other languages such as Chinese, Japanese, French, etc. By taking advantage of multi-lingual text resources provided by Thomson Reuters News, we developed two estimation algorithms for extracting cross-lingual news pairs from multilingual text resources. In our first method, we propose a novel structure that uses the word information and the machine learning method effectively in this task. Simultaneously, we developed a bidirectional Long Short-Term Memory (LSTM based method to calculate cross-lingual semantic text similarity for long text and short text, respectively. Thus, when an important news article is published, users can read similar news articles that are written in their native language using our method.

  1. Modeling news dissemination on nuclear issues

    International Nuclear Information System (INIS)

    Reis Junior, Jose S.B.; Barroso, Antonio C.O.; Menezes, Mario O.

    2011-01-01

    Using a modified epidemiological model, the dissemination of news by media agents after the occurrence of large scale disasters was studied. A modified compartmented model was developed in a previous paper presented at INAC 2007. There it used to study to the Chernobyl's nuclear accident (1986) and the Concorde airplane crash (2000). Now the model has been applied to a larger and more diverse group of events - nuclear, non-nuclear and naturally caused disasters. To be comprehensive, old and recent events from various regions of the world were selected. A more robust news repository was used, and improved search techniques were developed to ensure that the scripts would not count false positive news. The same model was used but with improved non-linear embedded simulation optimization algorithms to generate the parameters of interest for our model. Individual parameters and some specific combination of them allow some interesting perceptions on how the nature of the accident / disaster gives rise to different profiles of growth and decay of the news. In our studies events involving nuclear causes generate news repercussion with more explosive / robust surge profiles and longer decaying tails than those of other natures. As a consequence of these differences, public opinion and policy makers are also much more sensitive to some issues than to others. The model, through its epidemiological parameters, shows in quantitative manner how 'nervous' the media content generators are with respect to nuclear installations and how resilient this negative feelings about nuclear is.

  4. Determining Citizens’ Opinions About Stories in the News Media

    Directory of Open Access Journals (Sweden)

    Timo Wandhöfer

    2012-12-01

    Full Text Available We describe a method whereby a governmental policy maker can discover citizens’ reaction to news stories. This is particularly relevant in the political world, where governments’ policy statements are reported by the news media and discussed by citizens. The work here addresses two main questions: whereabouts are citizens discussing a news story, and what are they saying? Our strategy to answer the first question is to find news articles pertaining to the policy statements, then perform internet searches for references to the news articles’ headlines and URLs. We have created a software tool that schedules repeating Google searches for the news articles and collects the results in a database, enabling the user to aggregate and analyse them to produce ranked tables of sites that reference the news articles. Using data mining techniques we can analyse data so that resultant ranking reflects an overall aggregate score, taking into account multiple datasets, and this shows the most relevant places on the internet where the story is discussed. To answer the second question, we introduce the WeGov toolbox as a tool for analysing citizens’ comments and behaviour pertaining to news stories.  We first use the tool for identifying social network discussions, using different strategies for Facebook and Twitter. We apply different analysis components to analyse the data to distil the essence of the social network users’ comments, to determine influential users and identify important comments.

    2013-09-01

    Full Text Available Exposure to broadcast news by audience members is part of human information processing.  Radio is believed to be a major source of news on many local and national issues for many people in many countries. But it was uncertain whether the assumption was tenable in Nigeria. Selectivity plays significant role in audience members’ exposure to broadcast news.  The study set out to investigate which radio station(s residents of Uyo residents tune to for news on important local and national issues. It also studied what factors influence their choice of radio station for news on socio-political crises in Nigeria. The findings showed that majority of the respondents prefer foreign radio stations – Voice of America (VOA and British Broadcasting Corporation (BBC for news on socio-political crises in Nigeria. The survey also revealed that media credibility exerted great influence on audience exposure to broadcast news and choice of broadcast medium for news. It is the submission of this work that the continuous presentation of one-sided point of view, whether in government-controlled media or privately-owned ones not only makes the audience hold their news content suspect but also makes such mass medium to rank low in terms of perceived credibility. One of the implications of that situation is that mass mobilization through such media would be difficult to achieve.  Consequently, it is the submission of this research that if broadcast media in Nigeria are to be reckoned trustworthy and reliable, diverse and balanced views on all issues in the news should always be presented.

  13. AN EVALUATION OF TIMELINE VISUALIZATION AND TREE VIEWER IN CRIME NEWS

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available Finding good and relevant information in crime news is one of the most challenging tasks faced by users. An increase in the amount of information from news media has caused difficulties for users in obtaining relevant information. Hence, visualization is one of the important aspects to enhance user’s understanding when browsing or searching for news. Crime news requires a proper approach to visualize a variety of important information such as suspect, victim, location, time and evidence. Visual navigation is more interactive than linear. This has motivated us to develop a prototype called Crime News Visualization (CNV, which mplements a timeline and tree viewer to assist users when browsing crime news chronologically. The prototype follows several phases of development starting with design concept, implementation and evaluation. News corpus used in this study is from the Bernama Library & Infolink Service (BLIS resource, with a sample of 247 crime news documents from year 1997 to 2012. A user experiment was conducted with 20 undergraduate students from the Faculty of Social Science and Humanities, Universiti Kebangsaan Malaysia in order to evaluate the acceptance and perception of interactive browsing of crime news using news portal (baseline and CNV (experimental. Findings revealed that more than 90% of the respondents indicated that the use of timeline visualization and tree viewer was helpful and had potential to improve the way users browse for crime news content.

    2017-01-01

    The aim of this paper is to describe educational programs that reportedly teach how to break bad news in the emergency department. We also suggest some recommendations on how to communicate bad news based on the research of evidence available in the field. The examined evidence points toward six major components with which physicians should familiarize when communicating bad news: 1) doctor-patient empathic communication, 2) establishing a proper space to give the news, 3) identifying characteristics of the person who receives the news, 4) essential aspects for communicating the news; 5) emotional support, and 6) medical and administrative aspects of the encounter. Finally, we point out several limitations in the studies in the field and future challenges identified in the communication of bad news in emergency room facilities.

    2018-02-01

    Few studies are available on pediatricians' experience with announcing bad news. Announcing bad news is an important component of medical practice and is even more complex in pediatrics because parents must be associated. We had 20 hospital pediatricians complete a questionnaire containing 30 questions about their own experience announcing bad news to a child or a teenager. In spite of their experience and the time they have spent practicing medicine, there are many limitations stemming from different factors concerning children, teenagers, their families, and themselves. The difficulties encountered by pediatricians are mainly related to the timing of the announcement, the location, the choice of the words used, and the poor understanding of children and families, due to intellectual, cultural, or psychological limitations. Pediatricians question their own capacity to make such an announcement, wondering if the information has actually been well understood. They indicate that they are themselves affected. Most of them develop and implement strategies to refute the emotional instability caused by the announcement of bad news. Yet many of them feel weak, even talking about a deep sense of loneliness and guilt. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Full Text Available This article discusses the possibilities and challenges of the incorporation of wikis in journalistic editorial offices, especially in the processes involving the drafting and editing of texts. The reflection takes into consideration a context marked by 1 continuous fragmented publication of information; 2 simplification and horizontal organization of journalistic routines, which directly impacts the figure of the editor (mainly in the media on the web; and 3 increasing public participation in the development of the news, with the mediation of professionals. “Wiki-journalism” practices on the Wikinews and Wikipedia sites and initiatives originating with print publications are presented and discussed, and based on them we distinguish two models, which differ in the degree of control of the process by the journalists.

  19. A short guide to giving bad news.

    Mitchell, Jeffrey T

    2008-01-01

    Approaching an individual or a family with bad news, but without an appropriate plan to present the information in a structured manner, is almost a guarantee of greater emotional pain and disruption for the recipients of the news. Crisis interveners must develop a strategic plan for the announcement of bad news. That plan should entail a lead-up phase, a transmission phase, and a followup phase. The lead-up phase encompasses the gathering of accurate, verifiable information and the clear identification of the targets of the information. The transmission phase includes immediate preparation for the presentation of the information, the actual announcement, and the presentation of additional details as questions arise. The follow-up phase includes a range of supportive interventions to assist people in the immediate crisis reaction. It also includes a system of referrals for people who might benefit from additional professional care. This article provides practical guidelines for providing bad news to the loved ones of injured, ill, or deceased people.

  20. Measuring the Interestingness of News Articles

    Energy Technology Data Exchange (ETDEWEB)

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

    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.

    2008-01-01

    Knowledge management allows decommissioning stakeholders to take advantage of past experience (in terms of efficiency, quality, safety, cost, etc.), avoid repeating previous errors, and identify good ideas and practices. It is usually broken down into three processes: collecting information, supplementing and enriching it, and making it available to all decommissioning stakeholders. The CEA has been collecting and centralizing data for many years: the first qualitative assessment of operational experience began in 1991. However, the documents collected were not always relevant for this assessment and, for lack of enrichment and distribution, were generally not used to a significant extent. In order to take advantage of the existing and future body of knowledge and to share this knowledge among decommissioning stakeholders, the CEA decommissioning review unit decided to develop an intranet site known as BCD (from the French acronym for Central Decommissioning Database) using the same wiki technology as the collaborative web encyclopedia, Wikipedia. The objective of BCD is to develop a decommissioning encyclopedia comprising definitions and terminology, the regulatory framework, the lessons of experience with technical or contractual projects, guidelines, statements of results, etc. This article describes BCD and its potential, together with the results observed to date and its prospects for future development.

    2013-12-01

    Full Text Available The issues of British national identity and social cohesion have become pressing concerns within the multicultural fabric of contemporary British society. The increasing number of immigrants and their offspring, along with the maintenance of their cultural roots, seem to represent a serious defiance to social cohesion and the alleged “purity” of Britishness. A number of race related reports were produced by the official authorities to churn out the necessary steps to be followed by the British (immigrants and host community in order to keep social stability and community cohesion. Thus, the politics of community cohesion came to the fore as the neologism of contemporary British political discourse. Such new discourse of governance has been digested and processed differently by different mass media. It has been decoded, for instance, preferably by mainstream news agencies like BBC News Online. However, arguably, it is read appositionally or at best negotiatedly by ethnicity-related news agencies such as Muslim News Online. In this article, attempt has been made to adopt media discourse analysis tools to decipher the ways Muslim News Online decoded and then encoded the hegemonic official discourses of Britishness and community cohesion. A critical and interpretative approach is used to accomplish such study. The corpus of this study is primarily extracted from the website of the Muslim News Online.

    The entertainment and news industries are being transformed by the emergence of innovative, internet-based media tools. Audio and video downloads are beginning to compete with traditional entertainment distribution channels, and the blogosphere has become an alternative press with demonstrated news-making power of its own. The scientific community, and physics in particular, is just beginning to experiment with these tools. We believe that they have great potential for enhancing the quality and effectiveness of collaboration and communication, and that the coming generation of physicists will expect them to be used creatively. We will report on our experience in producing seminar podcasts (google ``QIBEC'' or search ``quantum'' on Apple iTunes), and on operating a distributed research institute using a group-based blog.

They are here as migrant labour, highly skilled and professional migrants (expatriates, illegal migrants, refugees, asylum-seekers (Burmese asylum seekers with UNHCR card, forced migrants (human trafficking victims, students, and tourists. The influx of foreign nationals residing in Malaysia coincides with greater number of crime news featuring foreign nationals. This study explores the social construction of foreign nationals as the ‘other’ in the local crime news published by Malaysian newspapers. 94 news headlines and lead sentences of local crime news involving foreign nationals were identified and analysed for this study. Findings suggest that Malaysian newspapers magnify foreign nationals’ migration status in each crime news.

    Full Text Available Habitualmente, la evaluación del alumnado que realizamos en la Universidad se basa únicamente en uno o varios exámenes individuales. Este hecho contrasta con su vida laboral posterior, donde se potenciará el trabajo en equipo, obteniendo la mayoría de los resultados a través de trabajos colaborativos. Con esta idea hemos realizado una experiencia docente en una asignatura optativa de la Diplomatura en Ciencias Empresariales, Investigación Operativa. Los alumnos de esta asignatura están distribuidos en tres grupos homogéneos de unos 20 alumnos. En cada uno de ellos hemos dedicado una parte importante de la calificación final a la realización de trabajos programados por los profesores, consistentes en realizar dentro de una plataforma Moodle, Wikis en los que cada grupo desarrolla un material predeterminado y conocido desde la programación del curso. Para cada grupo, cada uno de sus alumnos, deberá evaluar los Wikis realizados por los alumnos de los otros grupos, evaluación que ha de ser justificada y razonada, pudiendo cada profesor a su vez evaluarla de forma negativa o positiva.

    Full Text Available AIM: This study was performed in a descriptive matter to determine the views of inpatients at an oncology state hospital on receiving bad news. METHOD: The study sample consisted of 237 inpatients (155 females, 82 males at an oncology state hospital between October and November 2008 who were determined using the random sampling method and accepted participating in the study. The data collection tool used was a survey form that consisted of 24 questions related to the sociodemographic features and views on receiving bad news. RESULTS: The mean age of the study subjects was 53.1±13.9 (min.=18, max.=83. The patients were undergoing the treatment process in 84% and the diagnostic process in 16%. The bad news had been given by the physician in 87.8% and while in the physician's room in 74.8%. The patients had been told while receiving the bad news that 'there is a mass/problem/lesion/tumor and you will undergo surgery' in 47.7% while 24.9% had been told that they had cancer directly. The patients stated that they froze, fainted, were shocked, felt their life was shattered and experienced emotions such as sadness, fear, hopelessness, sorrow, disappointment, desperation, etc. at a rate of 93.7%. We found that 58.2% of the patients had not been given an opportunity to express their emotions when they received the bad news, 67.4% preferred to have a relative with them at the time, 40.9% felt that the bad news should be given in a special environment, 30% wanted the bad news to be given as soon as the diagnosis was known while 36.7% preferred being told everything about the disease when receiving the bad news CONCLUSION: Taking into account the information content, family participation, and the individual preferences of the patients regarding time and place when giving bad news and encouraging them to ask questions and express themselves may make it easier for the patients to cope with bad news.

    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

    Delivering bad news is a stressful moment for both physicians and patients. The purpose of this investigation was to explore the patients' preferences and attitudes toward being informed about the bad news. This cross-sectional study was done on patients admitted to Imam Khomeini Hospital, Sari, Iran, from September 2014 to February 2015. Patient attitude regarding breaking bad news was evaluated using a reliable and valid questionnaire. 130 patients were evaluated (61.5% male, mean age = 46.21 ± 12.1 years). 118 (90.76%) participants believed that the patient himself/herself should be informed about the disease's condition. 120 (92.30%) preferred to hear the news from a skillful physician and 105 (80.76%) believed that emergency department is not a proper place for breaking bad news. Based on the results of the present study, most participants believed that the most experienced and skillful physician should inform them completely regarding their medical condition. At the same time they declared that, it is best to hear bad news in a calm and suitable place and time rather than emergency department or hospital corridors during teaching rounds.

    Full Text Available Here, we describe a new Australian species in journal format and simultaneously open the description in a wiki format on the www.species-id.net. The wiki format will always link to the fixed original journal description of the taxon, however it permits future edits and additions to species'  taxonomy and biology. The diving beetle Neobidessodes darwiniensis sp. n. (Coleoptera, Dytiscidae, Bidessini is described based on a single female, collected in a rest pool of the Harriet Creek in the Darwin Area, Northern Territory. Within Neobidessodes the new species is well characterized by its elongate oval body with rounded sides, short and stout segments of antennae, length of body and dorsal surface coloration. In addition to external morphology, we used mitochondrial cox1 sequence data to support generic assignment and to delineate the new species from other Australian Bidessini including all other known Neobidessodes. Illustrations based on digital images are provided here and as online resources. A modified key is provided. Altogether ten species of the genus are now known worldwide, nine from Australia and one from New Guinea.

    2015-01-01

    Full Text Available An ontology-driven safe food consumption mobile system is considered. Over 3,000 compounds are being added to processed food, with numerous effects on the food: to add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so forth. According to World Health Organization, governments have lately focused on legislation to reduce such ingredients or compounds in manufactured foods as they may have side effects causing health risks such as heart disease, cancer, diabetes, allergens, and obesity. By supervising what and how much to eat as well as what not to eat, we can maximize a patient’s life quality through avoidance of unhealthy ingredients. Smart e-health systems with powerful knowledge bases can provide suggestions of appropriate foods to individuals. Next-generation smart knowledgebase systems will not only include traditional syntactic-based search, which limits the utility of the search results, but will also provide semantics for rich searching. In this paper, performance of concept matching of food ingredients is semantic-based, meaning that it runs its own semantic based rule set to infer meaningful results through the proposed Ontology-Driven Mobile Safe Food Consumption System (FoodWiki.

  6. From Reader to Writer: Citizen Journalism as News Produsage

    Science.gov (United States)

    Bruns, Axel

    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.

    Full Text Available This paper demonstrates that digital tools provide opportunities for new storytelling techniques. To take full advantage of the new media resources and to establish an innovative news narrative structure, the existing research limit and the relationship between narrative and the media were examined. This paper progresses from a discussion on the narrative structure to how the plot of a story is influenced by its discourse, and then to how different media characteristics can change the structure and voice of the involved narrative. A new narrative structure that can be used to explore the hypertext and interactivity of Internet news is described. Finally, this paper discusses the cultivation of news storytelling in the digital age.

    We present a Hawkes-model approach to the foreign exchange market in which the high-frequency price dynamics is affected by a self-exciting mechanism and an exogenous component, generated by the pre-announced arrival of macroeconomic news. By focusing on time windows around the news announcement, we find that the model is able to capture the increase of trading activity after the news, both when the news has a sizable effect on volatility and when this effect is negligible, either because the news in not important or because the announcement is in line with the forecast by analysts. We extend the model by considering noncausal effects, due to the fact that the existence of the news (but not its content) is known by the market before the announcement.

  13. From Adaptation to Appropriation: Framing the World Through News Translation

    Directory of Open Access Journals (Sweden)

    Valdeón Roberto A.

    2014-02-01

    Full Text Available Terminological issues are problematic in the analysis of translation processes in news production. In the 1980s, Stetting coined the term “transediting”, which has been widely used in the translation studies literature, but “translation” itself becomes contentious in communication studies, a discipline closely related to news translation research. Only a few communication scholars have specifically dealt with the linguistic and cultural transformations of source texts, but they tend to regard translation as word-for-word transfer, unusual news production. More productive for the study of news translation seems to be the application of the concept of framing, widely used in communication studies. Framing considers the linguistic and paralinguistic elements of news texts in the promotion of certain organizing ideas that the target audience can identify with. In news translation, this entails the adaptation of a text for the target readership, a process can lead to appropriation of source material. Two examples are mentioned to illustrate this point: the appropriation of the US Department of State cables by the Wikileak organisation, and the pro-Romanian slogans produced by the Gandul newspaper as a response to Britain’s anti-immigration campaigns. The final section relates news adaptation to adaptation of other text types, such as literary and historical works.

    Full Text Available Translation has always undergone the impact of various metalinguistic factors which impose their impact during the process of translation and rendering its final linguistic product. News stories or better to say political discourses are among those linguistic materials that more than other textual materials undergo the impact of factors such as ideology. Not being aware of such discursive practices leads the so-called translator to suffice to linguistic substitutions without observing imbedded intentions. For the purpose of this study through a qualitative type of research and based on critical discourse analysis (CDA approach for textual analysis and following Tymoczko’s concept of power (2002 in translation this study aimed to scrutinize the impact of power on Persian translations of different pieces of news stories in English in 2012. The corpus consists of some pieces of English news stories in worldwide news agencies (namely, Reuters, Washington Post, New York Post, and Forbes about Iran’s nuclear program. Results of the study showed that ideology is the very important stimulus which can control and direct the purpose of the news stories being translated from English to Persian and reveal its impact in a desired way as news stories for target audience.

    Herrera, Andrea; Ríos, Matías; Manríquez, José Manuel; Rojas, Gonzalo

    2014-10-01

    Breaking bad news is a complex task that requires multiple communication skills from health professionals. Clinical practice demands to communicate all type of bad news, from a diagnosis of cancer to adverse effects of a treatment. On the other hand, since the beginning of the health reform in 2003, the need to improve the quality of services was proposed, among which the concern about the rights and duties of patients stands out. Therefore, the health care provider-patient relationship becomes again the subject of discussion and study, and a topic of great importance for clinical work. We revise the consequences of breaking bad news for the patient and for the health care provider, as well as the current protocols available for this purpose. The importance of developing communication skills both for future health professionals as for those who currently work in the area is emphasized.

    2013-01-01

    Prior research indicates that the news media play a critical role in transmitting information to the public about the most pressing public health problems, and framing attributions about who in society is responsible for solving these problems. In this article, we use content analysis methods to study the agenda-setting and framing functions of the news media in shaping perceptions about the health risks posed by trans fat in the U.S. diet. A census of news stories focusing on trans fat was collected from the two largest circulation U.S. newspapers and three major television networks from 1998 to 2008 (N = 156). The content of news coverage was analyzed using a 23-item instrument. Findings indicated that the news media served an important agenda-setting role in educating the public about the presence of trans fat in the U.S. diet and describing the health risks these foods pose. In addition, results indicate that news media coverage framed attributions of responsibility for solving the problem of trans fat in the food supply. News stories noting the heart disease risks of trans fat were significantly more likely to mention governmental responses aimed at curbing consumption than news coverage that did not note these health risks.

  7. Contact: Releasing the news

    Science.gov (United States)

    Pinotti, Roberto

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

This study made a first step in this direction by investigating the effects of the colour red (compared with blue and grey) on the way news articles are evaluated. Two types of news were framed by a coloured border while the valence of the news content additionally varied. Based on 369 participants who read and evaluated the news articles online, we observed effects for colour cues and news valence in the absence of an interaction effect, indicating that the colour red induced approach motivation. However, only the contrast between red and grey reached statistical significance, indicating that chromatic and achromatic colours may differ in their perceived visual saliency. Overall, these results provide an important complement to previous studies and have practical implications for media researchers and producers. © 2015 International Union of Psychological Science.

    The reflection takes into consideration a context marked by 1
    continuous fragmented publication of information; 2 simplification
    and horizontal organization of journalistic routines, which directly
    impacts the figure of the editor (mainly in the media on the web; and 3 increasing public participation in the development of the news, with the mediation of professionals. “Wiki-journalism” practices on the Wikinews and Wikipedia sites and initiatives originating with print publications are presented and discussed, and based on them we distinguish two models, which differ in the degree of control of the process by the journalists.

    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. 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. 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%); pnews broadcasters had more mastery over the subject than the ones in satellite channels (pnews (pnews 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. 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

    Little is known about the news coverage of cancer risk factors in Korea. This study aimed to examine how the news media encompasses a wide array of content regarding cancer risk factors and related cancer sites, and investigate whether news coverage of cancer risk factors is congruent with the actual prevalence of the disease. A content analysis was conducted on 1,138 news stories covered during a 5-year period between 2008 and 2012. The news stories were selected from nationally representative media in Korea. Information was collected about cancer risk factors and cancer sites. Of various cancer risk factors, occupational and environmental exposures appeared most frequently in the news. Breast cancer was mentioned the most in relation to cancer sites. Breast, cervical, prostate, and skin cancer were overrepresented in the media in comparison to incidence and mortality cases, whereas lung, thyroid, liver, and stomach cancer were underrepresented. To our knowledge, this research is the first investigation dealing with news coverage about cancer risk factors in Korea. The study findings show occupational and environmental exposures are emphasized more than personal lifestyle factors; further, more prevalent cancers in developed countries have greater media coverage, not reflecting the realities of the disease. The findings may help health journalists and other health storytellers to develop effective ways to communicate cancer risk factors.

    Framing in news is the way in which journalists depict an issue in terms of a ‘central organizing idea.’ Frames can be a perspective on an issue. We explore the automatic classification of four generic news frames: conflict, human interest, economic consequences, and morality. Complex

    Full Text Available In this initial phase of our multi-year research study we set out to explore the development of leadership skills in our pre-service secondary teachers after using an online wiki, Wikispaces. This paper presents our methods for preparing a group of 13 mathematics and 3 science secondary pre-service teachers to demonstrate the essential knowledge, skills and dispositions of beginning teacher leaders. Our findings indicate the pre-service teachers' overall satisfaction with demonstrating leadership through collaborative practices. They were successful in these new roles as teacher/collaborator within the context of communication about content standards. Though the candidates participated in other collaborative tasks, this effort was noted for bringing together technology, content standards and leadership qualities that are critical for beginning teachers. Implications for addressing the preservice teachers' development of leadership skills, as they become professional teachers will be shared.

    Society always has limited resources to expend on health care, or anything else. What are the unmet medical needs? How do we allocate limited resources to maximize the health and welfare of the people? These challenging questions might be re-examined systematically within an infodemiological frame on a much larger scale, leveraging the latest advancement in information technology and data science. We expanded our previous work by investigating news media data to reveal the coverage of different diseases and medical conditions, together with their sentiments and topics in news articles over three decades. We were motivated to do so since news media plays a significant role in politics and affects the public policy making. We analyzed over 3.5 million archive news articles from Reuters media during the periods of 1996/1997, 2008 and 2016, using summary statistics, sentiment analysis, and topic modeling. Summary statistics illustrated the coverage of various diseases and medical conditions during the last 3 decades. Sentiment analysis and topic modeling helped us automatically detect the sentiments of news articles (ie, positive versus negative) and topics (ie, a series of keywords) associated with each disease over time. The percentages of news articles mentioning diseases and medical conditions were 0.44%, 0.57% and 0.81% in the three time periods, suggesting that news media or the public has gradually increased its interests in medicine since 1996. Certain diseases such as other malignant neoplasm (34%), other infectious diseases (20%), and influenza (11%) represented the most covered diseases. Two hundred and twenty-six diseases and medical conditions (97.8%) were found to have neutral or negative sentiments in the news articles. Using topic modeling, we identified meaningful topics on these diseases and medical conditions. For instance, the smoking theme appeared in the news articles on other malignant neoplasm only during 1996/1997. The topic phrases HIV and

    The validation of land cover products is an important step in the workflow of generating a land cover map from remotely-sensed imagery. Many students of remote sensing will be given exercises on classifying a land cover map followed by the validation process. Many algorithms exist for classification, embedded within proprietary image processing software or increasingly as open source tools. However, there is little standardization for land cover validation, nor a set of open tools available for implementing this process. The LACO-Wiki tool was developed as a way of filling this gap, bringing together standardized land cover validation methods and workflows into a single portal. This includes the storage and management of land cover maps and validation data; step-by-step instructions to guide users through the validation process; sound sampling designs; an easy-to-use environment for validation sample interpretation; and the generation of accuracy reports based on the validation process. The tool was developed for a range of users including producers of land cover maps, researchers, teachers and students. The use of such a tool could be embedded within the curriculum of remote sensing courses at a university level but is simple enough for use by students aged 13-18. A beta version of the tool is available for testing at: http://www.laco-wiki.net.

    Full Text Available "nObjective: Bad news disclosure is one of the most complex tasks of physicians. Recent evidences indicate that patients' and physicians' attitude toward breaking bad news has been changed since few years ago. The evidence of breaking bad news is different across cultures. The aim of this study is to evaluate the attitude of medical staff toward breaking bad news to provide a clinical guideline in Iran."nMethods: A descriptive study was conducted during 2008-2009 on a sample of 100 medical staff (50 physicians and 50 nurses at Cancer Institute of Imam Khomeini hospital. The subjects' demographic characteristics and their attitudes toward the manner of revealing the diagnosis were registered in a questionnaire."nResults: The majority of the physicians (86%, n=43 and nurses (74%, n=37 , mostly the older and more experienced, tended to reveal the diagnosis to patients . Only a few physicians (8%, n=4 had been trained how to disclose bad news, which discloused diagnosis more than non trained ones."nPhysicians and nurses preferred to inform the patients about the diagnosis when either the patients were alone or in the presence of their spouse respectively .Only a few physicians (14% and nurses (24% agreed to explain life expectancy to patients."nConclusion: Compared to past, physicians and nurses are more willing to share cancer diagnosis with patients. However, lack of adequate communication skills in caregivers, and their concerns about managing patients' emotional reactions reduce their tendency to disclose bad news to the patients. Therefore, training physicians and nurses to expose bad news to the patients seems to be necessary.
