    2017-06-01

    Full Text Available This paper describes an analysis conducted in 2015 to evaluate the accessibility of content on Andalusian public university websites. In order to determinate whether these websites are accessible, an assessment has been carried out to check conformance with the latest Web Content Accessibility Guidelines (WCAG 2.0 established by the World Wide Web Consortium (W3C. For this purpose, we have designed a methodology for analysis that combines the use of three automatic tools (eXaminator, MINHAP web accessibility tool, and TAW with a manual analysis to provide a greater reliability and validity of the results. Although the results are acceptable overall, a detailed analysis shows that more is still needed for achieving full accessibility for the entire university community. In this respect, we suggest several corrections to common accessibility errors for facilitating the design of university web portals.

  2. Web Accessibility and Guidelines

    Science.gov (United States)

    Harper, Simon; Yesilada, Yeliz

    Access to, and movement around, complex online environments, of which the World Wide Web (Web) is the most popular example, has long been considered an important and major issue in the Web design and usability field. The commonly used slang phrase ‘surfing the Web’ implies rapid and free access, pointing to its importance among designers and users alike. It has also been long established that this potentially complex and difficult access is further complicated, and becomes neither rapid nor free, if the user is disabled. There are millions of people who have disabilities that affect their use of the Web. Web accessibility aims to help these people to perceive, understand, navigate, and interact with, as well as contribute to, the Web, and thereby the society in general. This accessibility is, in part, facilitated by the Web Content Accessibility Guidelines (WCAG) currently moving from version one to two. These guidelines are intended to encourage designers to make sure their sites conform to specifications, and in that conformance enable the assistive technologies of disabled users to better interact with the page content. In this way, it was hoped that accessibility could be supported. While this is in part true, guidelines do not solve all problems and the new WCAG version two guidelines are surrounded by controversy and intrigue. This chapter aims to establish the published literature related to Web accessibility and Web accessibility guidelines, and discuss limitations of the current guidelines and future directions.

    Full Text Available The accessibility of public administration web sites is a key quality attribute for the successful implementation of the Information Society. The purpose of this paper is to present a second review of municipal web sites in Romania that is based on automated accessibility checking. A number of 60 web sites were evaluated against WCAG 2.0 recommendations. The analysis of results reveals a relatively low web accessibility of municipal web sites and highlights several aspects. Firstly, a slight progress in web accessibility was noticed as regarded the sample evaluated in 2010. Secondly, the number of specific accessibility errors is varying across the web sites and the accessibility is not preserved in time. Thirdly, these variations suggest that an accessibility check before launching a new release for a web page is not a common practice.

    “As Bill Gates and Steve Case proclaim the global omnipresence of the Internet, the majority of non-Western nations and 97 per cent of the world's population remain unconnected to the net for lack of money, access, or knowledge. This exclusion of so vast a share of the global population from the Internet sharply contradicts the claims of those who posit the World Wide Web as a ‘universal' medium of egalitarian communication.” (Trend 2001:2)

  7. A Secure Web Application Providing Public Access to High-Performance Data Intensive Scientific Resources - ScalaBLAST Web Application

    Energy Technology Data Exchange (ETDEWEB)

    Curtis, Darren S.; Peterson, Elena S.; Oehmen, Chris S.

    2008-05-04

    This work presents the ScalaBLAST Web Application (SWA), a web based application implemented using the PHP script language, MySQL DBMS, and Apache web server under a GNU/Linux platform. SWA is an application built as part of the Data Intensive Computer for Complex Biological Systems (DICCBS) project at the Pacific Northwest National Laboratory (PNNL). SWA delivers accelerated throughput of bioinformatics analysis via high-performance computing through a convenient, easy-to-use web interface. This approach greatly enhances emerging fields of study in biology such as ontology-based homology, and multiple whole genome comparisons which, in the absence of a tool like SWA, require a heroic effort to overcome the computational bottleneck associated with genome analysis. The current version of SWA includes a user account management system, a web based user interface, and a backend process that generates the files necessary for the Internet scientific community to submit a ScalaBLAST parallel processing job on a dedicated cluster.

  9. From Web accessibility to Web adaptability.

    2009-07-01

    This article asserts that current approaches to enhance the accessibility of Web resources fail to provide a solid foundation for the development of a robust and future-proofed framework. In particular, they fail to take advantage of new technologies and technological practices. The article introduces a framework for Web adaptability, which encourages the development of Web-based services that can be resilient to the diversity of uses of such services, the target audience, available resources, technical innovations, organisational policies and relevant definitions of 'accessibility'. The article refers to a series of author-focussed approaches to accessibility through which the authors and others have struggled to find ways to promote accessibility for people with disabilities. These approaches depend upon the resource author's determination of the anticipated users' needs and their provision. Through approaches labelled as 1.0, 2.0 and 3.0, the authors have widened their focus to account for contexts and individual differences in target audiences. Now, the authors want to recognise the role of users in determining their engagement with resources (including services). To distinguish this new approach, the term 'adaptability' has been used to replace 'accessibility'; new definitions of accessibility have been adopted, and the authors have reviewed their previous work to clarify how it is relevant to the new approach. Accessibility 1.0 is here characterised as a technical approach in which authors are told how to construct resources for a broadly defined audience. This is known as universal design. Accessibility 2.0 was introduced to point to the need to account for the context in which resources would be used, to help overcome inadequacies identified in the purely technical approach. Accessibility 3.0 moved the focus on users from a homogenised universal definition to recognition of the idiosyncratic needs and preferences of individuals and to cater for them. All of

    Full Text Available With an abundance of library resources being served on the web, researchers are finding that disabled people oftentimes do not have the same level of access to materials as their nondisabled peers. This paper discusses web accessibility in the context of United States’ federal laws most referenced in web accessibility lawsuits. Additionally, it reveals which states have statutes that mirror federal web accessibility guidelines and to what extent. Interestingly, fewer than half of the states have adopted statutes addressing web accessibility, and fewer than half of these reference Section 508 of the Rehabilitation Act or Web Content Accessibility Guidelines (WCAG 1.0. Regardless of sparse legislation surrounding web accessibility, librarians should consult the appropriate web accessibility resources to ensure that their specialized content reaches all.

  14. Evaluation of a web portal for improving public access to evidence-based health information and health literacy skills: a pragmatic trial.

    Directory of Open Access Journals (Sweden)

    Astrid Austvoll-Dahlgren

    Full Text Available BACKGROUND: Using the conceptual framework of shared decision-making and evidence-based practice, a web portal was developed to serve as a generic (non disease-specific tailored intervention to improve the lay public's health literacy skills. OBJECTIVE: To evaluate the effects of the web portal compared to no intervention in a real-life setting. METHODS: A pragmatic randomised controlled parallel trial using simple randomisation of 96 parents who had children aged <4 years. Parents were allocated to receive either access to the portal or no intervention, and assigned three tasks to perform over a three-week period. These included a searching task, a critical appraisal task, and reporting on perceptions about participation. Data were collected from March through June 2011. RESULTS: Use of the web portal was found to improve attitudes towards searching for health information. This variable was identified as the most important predictor of intention to search in both samples. Participants considered the web portal to have good usability, usefulness, and credibility. The intervention group showed slight increases in the use of evidence-based information, critical appraisal skills, and participation compared to the group receiving no intervention, but these differences were not statistically significant. CONCLUSION: Despite the fact that the study was underpowered, we found that the web portal may have a positive effect on attitudes towards searching for health information. Furthermore, participants considered the web portal to be a relevant tool. It is important to continue experimenting with web-based resources in order to increase user participation in health care decision-making. TRIAL REGISTRATION: ClinicalTrials.gov NCT01266798.

  15. Web Accessibility - A timely recognized challenge

    2011-01-01

    Web Accessibility for disabled people has posed a challenge to the civilized societies that claim to uphold the principles of equal opportunity and nondiscrimination. Certain concrete measures have been taken to narrow down the digital divide between normal and disabled users of Internet technology. The efforts have resulted in enactment of legislations and laws and mass awareness about the discriminatory nature of the accessibility issue, besides the efforts have resulted in the development of commensurate technological tools to develop and test the Web accessibility. World Wide Web consortium's (W3C) Web Accessibility Initiative (WAI) has framed a comprehensive document comprising of set of guidelines to make the Web sites accessible to the users with disabilities. This paper is about the issues and aspects surrounding Web Accessibility. The details and scope are kept limited to comply with the aim of the paper which is to create awareness and to provide basis for in-depth investigation.

    2016-08-01

    Despite the fact that Malaysian public institutions have progressed considerably on website and portal usage, web accessibility has been reported as one of the issues deserves special attention. Consistent with the government moves to promote an effective use of web and portal, it is essential for the government institutions to ensure compliance with established standards and guidelines on web accessibility. This paper evaluates accessibility of 25 Malaysian ministries websites using automated tools i.e. WAVE and Achecker. Both tools are designed to objectively evaluate web accessibility in conformance with Web Content Accessibility Guidelines 2.0 (WCAG 2.0) and United States Rehabilitation Act 1973 (Section 508). The findings reported somewhat low compliance to web accessibility standard amongst the ministries. Further enhancement is needed in the aspect of input elements such as label and checkbox to be associated with text as well as image-related elements. This findings could be used as a mechanism for webmasters to locate and rectify errors pertaining to the web accessibility and to ensure equal access of the web information and services to all citizen.

  18. Web accessibility standards and disability: developing critical perspectives on accessibility.

    Science.gov (United States)

    Lewthwaite, Sarah

    2014-01-01

    Currently, dominant web accessibility standards do not respect disability as a complex and culturally contingent interaction; recognizing that disability is a variable, contrary and political power relation, rather than a biological limit. Against this background there is clear scope to broaden the ways in which accessibility standards are understood, developed and applied. Commentary. The values that shape and are shaped by legislation promote universal, statistical and automated approaches to web accessibility. This results in web accessibility standards conveying powerful norms fixing the relationship between technology and disability, irrespective of geographical, social, technological or cultural diversity. Web accessibility standards are designed to enact universal principles; however, they express partial and biopolitical understandings of the relation between disability and technology. These values can be limiting, and potentially counter-productive, for example, for the majority of disabled people in the "Global South" where different contexts constitute different disabilities and different experiences of web access. To create more robust, accessible outcomes for disabled people, research and standards practice should diversify to embrace more interactional accounts of disability in different settings. Implications for Rehabilitation Creating accessible experiences is an essential aspect of rehabilitation. Web standards promote universal accessibility as a property of an online resource or service. This undervalues the importance of the user's intentions, expertize, their context, and the complex social and cultural nature of disability. Standardized, universal approaches to web accessibility may lead to counterproductive outcomes for disabled people whose impairments and circumstances do not meet Western disability and accessibility norms. Accessible experiences for rehabilitation can be enhanced through an additional focus on holistic approaches to

    This paper describes the design and evaluation of a Web Accessibility Information Resource (WebAIR) for supporting web developers to create and evaluate accessible websites. WebAIR was designed with web developers in mind, recognising their current working practices and acknowledging their existing understanding of web accessibility. We conducted an evaluation with 32 professional web developers in which they used either WebAIR or an existing accessibility information resource, the Web Content Accessibility Guidelines, to identify accessibility problems. The findings indicate that several design decisions made in relation to the language, organisation, and volume of WebAIR were effective in supporting web developers to undertake web accessibility evaluations.

  20. Web accessibility and open source software.

    Obrenović, Zeljko

    2009-07-01

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

  1. Ten years for the public Web

    CERN Multimedia

    2003-01-01

    Ten years ago, CERN issued a statement declaring that a little known piece of software called the World Wide Web was in the public domain. Nowadays, the Web is an indispensable part of modern communications. The idea for the Web goes back to March 1989 when CERN Computer scientist Tim Berners-Lee wrote a proposal for a 'Distributed Information Management System' for the high-energy physics community. The Web was originaly conceived and developed to meet the demand for information sharing between scientists working all over the world. There were many obstacles in the 1980s to the effective exchange of information. There was, for example a great variety of computer and network systems, with hardly any common features. The main purpose of the web was to allow scientists to access information from any source in a consistent and simple way. By Christmas 1990, Berners-Lee's idea had become the World Wide Web, with its first server and browser running at CERN. Through 1991, the Web spread to other particle physics ...

  2. Public Access Technologies in Public Libraries: Effects and Implications

    Directory of Open Access Journals (Sweden)

    John Carlo Bertot

    2009-06-01

    Full Text Available Public libraries were early adopters of Internet-based technologies and have provided public access to the Internet and computers since the early 1990s. The landscape of public-access Internet and computing was substantially different in the 1990s as the World Wide Web was only in its initial development. At that time, public libraries essentially experimented with publicaccess Internet and computer services, largely absorbing this service into existing service and resource provision without substantial consideration of the management, facilities, staffing, and other implications of public-access technology (PAT services and resources. This article explores the implications for public libraries of the provision of PAT and seeks to look further to review issues and practices associated with PAT provision resources. While much research focuses on the amount of public access that public libraries provide, little offers a view of the effect of public access on libraries. This article provides insights into some of the costs, issues, and challenges associated with public access and concludes with recommendations that require continued exploration.

    Web mapping sites are interactive maps that are accessed via Webpages. With the rapid development of Internet and Geographic Information System (GIS) field, public web mapping sites are not foreign to people. Nowadays, people use these web mapping sites for various reasons, in that increasing maps and related map services of web mapping sites are freely available for end users. Thus, increased users of web mapping sites led to more usability studies. Usability Engineering (UE), for instance, is an approach for analyzing and improving the usability of websites through examining and evaluating an interface. In this research, UE method was employed to explore usability problems of four public web mapping sites, analyze the problems quantitatively and provide guidelines for future design based on the test results. Firstly, the development progress for usability studies were described, and simultaneously several usability evaluation methods such as Usability Engineering (UE), User-Centered Design (UCD) and Human-Computer Interaction (HCI) were generally introduced. Then the method and procedure of experiments for the usability test were presented in detail. In this usability evaluation experiment, four public web mapping sites (Google Maps, Bing maps, Mapquest, Yahoo Maps) were chosen as the testing websites. And 42 people, who having different GIS skills (test users or experts), gender (male or female), age and nationality, participated in this test to complete the several test tasks in different teams. The test comprised three parts: a pretest background information questionnaire, several test tasks for quantitative statistics and progress analysis, and a posttest questionnaire. The pretest and posttest questionnaires focused on gaining the verbal explanation of their actions qualitatively. And the design for test tasks targeted at gathering quantitative data for the errors and problems of the websites. Then, the results mainly from the test part were analyzed. The

    Modern Web sites use several techniques (e.g. DOM manipulation) that allow for the injection of new content into their Web pages (e.g. AJAX), as well as manipulation of the HTML DOM tree. This has the consequence that the Web pages that are presented to users (i.e. after browser processing) are different from the original structure and content that is transmitted through HTTP communication (i.e. after browser processing). This poses a series of challenges for Web accessibility evaluation, especially on automated evaluation software. This article details an experimental study designed to understand the differences posed by accessibility evaluation after Web browser processing. We implemented a Javascript-based evaluator, QualWeb, that can perform WCAG 2.0 based accessibility evaluations in the two phases of browser processing. Our study shows that, in fact, there are considerable differences between the HTML DOM trees in both phases, which have the consequence of having distinct evaluation results. We discuss the impact of these results in the light of the potential problems that these differences can pose to designers and developers that use accessibility evaluators that function before browser processing.

    2011-06-01

    Full Text Available Abstract Background Many bioinformatics algorithms and data sets are deployed using web services so that the results can be explored via the Internet and easily integrated into other tools and services. These services often include data from other sites that is accessed either dynamically or through file downloads. Developers of these services face several problems because of the dynamic nature of the information from the upstream services. Many publicly available repositories of bioinformatics data frequently update their information. When such an update occurs, the developers of the downstream service may also need to update. For file downloads, this process is typically performed manually followed by web service restart. Requests for information obtained by dynamic access of upstream sources is sometimes subject to rate restrictions. Findings SideCache provides a framework for deploying web services that integrate information extracted from other databases and from web sources that are periodically updated. This situation occurs frequently in biotechnology where new information is being continuously generated and the latest information is important. SideCache provides several types of services including proxy access and rate control, local caching, and automatic web service updating. Conclusions We have used the SideCache framework to automate the deployment and updating of a number of bioinformatics web services and tools that extract information from remote primary sources such as NCBI, NCIBI, and Ensembl. The SideCache framework also has been used to share research results through the use of a SideCache derived web service.

    The Access To Space (ATS) Group at NASA's Goddard Space Flight Center (GSFC) supports the science and technology community at GSFC by facilitating frequent and affordable opportunities for access to space. Through partnerships established with access mode suppliers, the ATS Group has developed an interactive Mission Design web site. The ATS web site provides both the information and the tools necessary to assist mission planners in selecting and planning their ride to space. This includes the evaluation of single payloads vs. ride-sharing opportunities to reduce the cost of access to space. Features of this site include the following: (1) Mission Database. Our mission database contains a listing of missions ranging from proposed missions to manifested. Missions can be entered by our user community through data input tools. Data is then accessed by users through various search engines: orbit parameters, ride-share opportunities, spacecraft parameters, other mission notes, launch vehicle, and contact information. (2) Launch Vehicle Toolboxes. The launch vehicle toolboxes provide the user a full range of information on vehicle classes and individual configurations. Topics include: general information, environments, performance, payload interface, available volume, and launch sites.

    2008-07-01

    This article examines the nature and role of Web 2.0 resources and their impact on health information made available though the Internet. The transition of the Web from version one to Web 2.0 is described and the main features of the new Web examined. Two characteristic Web 2.0 resources are explored and the implications for the public and practitioners examined. First, what are known as 'user reviews' or 'user testimonials', which allow people to comment on the health services delivered to them, are described. Second, new mapping applications that take advantage of the interactive potential of Web 2.0 and provide tools to visualize complex data are examined. Following a discussion of the potential of Web 2.0, it is concluded that it offers considerable opportunities for disseminating health information and creating new sources of data, as well as generating new questions and dilemmas.

    2012-01-01

    Integrating open data sources can yield high value information but raises major problems in terms of metadata extraction, data source integration and visualization of integrated data. In this paper, we describe WebSmatch, a flexible environment for Web data integration, based on a real, end-to-end data integration scenario over public data from Data Publica. WebSmatch supports the full process of importing, refining and integrating data sources and uses third party tools for high quality visualization. We use a typical scenario of public data integration which involves problems not solved by currents tools: poorly structured input data sources (XLS files) and rich visualization of integrated data.

    Full Text Available Libraries should offer their patrons web sites which establish the unmistakeable concept (public of library, the concept that cannot be mistaken for other information brokers and services available on the Internet, but inside this framework of the concept of library, would show a diversity which directs patrons to other (public libraries. This can be achieved by reliability, quality of information and services, and safety of usage.Achieving this, patrons regard library web sites as important reference sources deserving continuous usage for obtaining relevant information. Libraries excuse investment in the development and sustainance of their web sites by the number of visits and by patron satisfaction. The presented research, made on a sample of Slovene public libraries’web sites, determines how the libraries establish their purpose and role, as well as the given professional recommendations in web site design.The results uncover the striving of libraries for the modernisation of their functions,major attention is directed to the presentation of classic libraries and their activities,lesser to the expansion of available contents and electronic sources. Pointing to their diversity is significant since it is not a result of patrons’ needs, but more the consequence of improvisation, too little attention to selection, availability, organisation and formation of different kind of information and services on the web sites. Based on the analysis of a common concept of the public library web site, certain activities for improving the existing state of affairs are presented in the paper.

    Full Text Available Semantic Web approaches try to get the interoperability and communication among technologies and organizations. Nevertheless, sometimes it is forgotten that the Web must be useful for every user, consequently it is necessary to include tools and techniques doing Semantic Web be accessible. Accessibility and usability are two usually joined concepts widely used in web application development, however their meaning are different. Usability means the way to make easy the use but accessibility is referred to the access possibility. For the first one, there are many well proved approaches in real cases. However, accessibility field requires a deeper research that will make feasible the access to disable people and also the access to novel non-disable people due to the cost to automate and maintain accessible applications. In this paper, we propose one architecture to achieve the accessibility in web-environments dealing with the WAI accessibility standard and the Universal Design paradigm. This architecture tries to control the accessibility in web applications development life-cycle following a methodology starting from a semantic conceptual model and leans on description languages and controlled vocabularies.

    Simone Chiadò Piat

    2010-06-01

    Full Text Available

    Background: Since the large volume of health information available on the Web has the potential to improve health, Public Health institutions must represent a strong Internet presence with accessible and scientific information. The aims of the study were to verify the presence and visibility of Italian Institutions on the Web and to evaluate the accessibility and quality of the information provided.

    Methods: In a focus group setting, 21 keywords were generated, and launched in search-engines Google and MSN. Researchers noted the first 30 results found and determined the position of institutional websites. The accessibility of 303 Public Health websites was assessed in relation to the logo presence and web validation of XHTML, CSS and WAI indicators. Regarding the quality of information, the presence of the HONcode logo in the websites’ homepage was checked.

    Results: A high percentage of the keywords selected did not lead to any institutional website in the first three pages of Google (19.0% and MSN (42.8%. Few institutional websites presented the logo indicator and a full web validation. Considering the XHTML indicator, only for 34.0% of the websites there was concordance between the logo presence/absence and results of direct validation, 50.2% for CSS. The quality level seemed to be extremely low.

    Conclusions:In order to achieve a larger visibility and guarantee accessibility, Public Health websites have to be correctly designed, edited and maintained. Common and strict European laws about health information on the Web have to be arranged, deeply monitored and carefully adjourned in order to guarantee and support the positive role of institutional websites.

  2. Accessing the SEED Genome Databases via Web Services API: Tools for Programmers

    Directory of Open Access Journals (Sweden)

    Vonstein Veronika

    2010-06-01

    Full Text Available Abstract Background The SEED integrates many publicly available genome sequences into a single resource. The database contains accurate and up-to-date annotations based on the subsystems concept that leverages clustering between genomes and other clues to accurately and efficiently annotate microbial genomes. The backend is used as the foundation for many genome annotation tools, such as the Rapid Annotation using Subsystems Technology (RAST server for whole genome annotation, the metagenomics RAST server for random community genome annotations, and the annotation clearinghouse for exchanging annotations from different resources. In addition to a web user interface, the SEED also provides Web services based API for programmatic access to the data in the SEED, allowing the development of third-party tools and mash-ups. Results The currently exposed Web services encompass over forty different methods for accessing data related to microbial genome annotations. The Web services provide comprehensive access to the database back end, allowing any programmer access to the most consistent and accurate genome annotations available. The Web services are deployed using a platform independent service-oriented approach that allows the user to choose the most suitable programming platform for their application. Example code demonstrate that Web services can be used to access the SEED using common bioinformatics programming languages such as Perl, Python, and Java. Conclusions We present a novel approach to access the SEED database. Using Web services, a robust API for access to genomics data is provided, without requiring large volume downloads all at once. The API ensures timely access to the most current datasets available, including the new genomes as soon as they come online.

    Full Text Available The need to provide open access to articles published in peer-reviewed scholarly journals is becoming apparent to researchers as well as the non-scientific public as a result of "Budapest Open Access Initiative," the "Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities" and other initiatives. The core question that concerns open access is the following: since scientific information is usually financed by public funding, and therefore a public good, shouldn't the access be free of cost to all interested parties. Currently the open access movement is encountering the movement against the "Digital Divide," and therefore it is not surprising that the demand for open access has extended to a political level as reflected in the "WSIS Declaration of Principles" and the "WSIS Plan of Action." This article begins by providing a brief summary of the historical background of the open access movement and its major aims (Section 2. It then lists examples that explain possible links between the open access movement and the initiatives against the "Digital Divide" (Section 3. Section 4 considers some important barriers responsible for the fact that open access publishing is still not part of the everyday scientific publishing practices. This has various consequences.

    Full Text Available Problems with mathematics learning, “math anxiety” or “statistics anxiety” among university students can be avoided by using teaching strategies and technological tools. Besides personal suffering, low achievement in mathematics reduces terminal efficiency and decreases enrollment in careers related to science, technology and mathematics. This paper has two main goals: 1 to offer an organized inventory of open access web resources for math learning in higher education, and 2 to explore to what extent these resources are currently known and used by students and teachers. The first goal was accomplished by running a search in Google and then classifying resources. For the second, we conducted a survey among a sample of students (n=487 and teachers (n=60 from mathematics and engineering within the largest public university in Mexico. We categorized 15 high-quality web resources. Most of them are interactive simulations and computer algebra systems. ResumenLos problemas en el aprendizaje de las matemáticas, como “ansiedad matemática” y “ansiedad estadística” pueden evitarse si se usan estrategias de enseñanza y herramientas tecnológicas.

  11. Access to scientific publications: the scientist's perspective.

    Directory of Open Access Journals (Sweden)

    Yegor Voronin

    Full Text Available BACKGROUND: Scientific publishing is undergoing significant changes due to the growth of online publications, increases in the number of open access journals, and policies of funders and universities requiring authors to ensure that their publications become publicly accessible. Most studies of the impact of these changes have focused on the growth of articles available through open access or the number of open-access journals. Here, we investigated access to publications at a number of institutes and universities around the world, focusing on publications in HIV vaccine research--an area of biomedical research with special importance to the developing world. METHODS AND FINDINGS: We selected research papers in HIV vaccine research field, creating: 1 a first set of 50 most recently published papers with keywords "HIV vaccine" and 2 a second set of 200 articles randomly selected from those cited in the first set. Access to the majority (80% of the recently published articles required subscription, while cited literature was much more accessible (67% freely available online. Subscriptions at a number of institutions around the world were assessed for providing access to subscription-only articles from the two sets. The access levels varied widely, ranging among institutions from 20% to 90%. Through the WHO-supported HINARI program, institutes in low-income countries had access comparable to that of institutes in the North. Finally, we examined the response rates for reprint requests sent to corresponding authors, a method commonly used before internet access became widespread. Contacting corresponding authors with requests for electronic copies of articles by email resulted in a 55-60% success rate, although in some cases it took up to 1.5 months to get a response. CONCLUSIONS: While research articles are increasingly available on the internet in open access format, institutional subscriptions continue to play an important role. However

    Full Text Available In the study; the assessment of accessibility has been conducted in Istanbul public libraries within the scope of public area. Public libraries commonly serve with its user of more than 20 million in total, spread to the general of Turkey, having more than one thousand branches in the centrums and having more than one million registered members. The building principles and standards covering the subjects such as the selection of place, historical and architectural specification of the region, distance to the centre of population and design in a way that the disabled people could benefit from the library services fully have been determined with regulations in the construction of new libraries. There are works for the existent libraries such as access for the disabled, fire safety precautions etc. within the scope of the related standards. Easy access by everyone is prioritized in the public libraries having a significant role in life-long learning. The purpose of the study is to develop solution suggestions for the accessibility problems in the public libraries. The study based on the eye inspection and assessments carried out within the scope of accessibility in the public libraries subsidiary to Istanbul Culture and Tourism Provincial Directorate Library and Publications Department within the provincial borders of Istanbul. The arrangements such as reading halls, study areas, book shelves etc. have been examined within the frame of accessible building standards. Building entrances, ramps and staircases, horizontal and vertical circulation of building etc. have been taken into consideration within the scope of accessible building standards. The subjects such as the reading and studying areas and book shelf arrangements for the library have been assessed within the scope of specific buildings.

  14. Learning Task Knowledge from Dialog and Web Access

    Full Text Available We present KnoWDiaL, an approach for Learning and using task-relevant Knowledge from human-robot Dialog and access to the Web. KnoWDiaL assumes that there is an autonomous agent that performs tasks, as requested by humans through speech. The agent needs to “understand” the request, (i.e., to fully ground the task until it can proceed to plan for and execute it. KnoWDiaL contributes such understanding by using and updating a Knowledge Base, by dialoguing with the user, and by accessing the web. We believe that KnoWDiaL, as we present it, can be applied to general autonomous agents. However, we focus on our work with our autonomous collaborative robot, CoBot, which executes service tasks in a building, moving around and transporting objects between locations. Hence, the knowledge acquired and accessed consists of groundings of language to robot actions, and building locations, persons, and objects. KnoWDiaL handles the interpretation of voice commands, is robust regarding speech recognition errors, and is able to learn commands involving referring expressions in an open domain, (i.e., without requiring a lexicon. We present in detail the multiple components of KnoWDiaL, namely a frame-semantic parser, a probabilistic grounding model, a web-based predicate evaluator, a dialog manager, and the weighted predicate-based Knowledge Base. We illustrate the knowledge access and updates from the dialog and Web access, through detailed and complete examples. We further evaluate the correctness of the predicate instances learned into the Knowledge Base, and show the increase in dialog efficiency as a function of the number of interactions. We have extensively and successfully used KnoWDiaL in CoBot dialoguing and accessing the Web, and extract a few corresponding example sequences from captured videos.

  15. Access Control of Web- and Java-Based Applications

    2013-01-01

    Cybersecurity has become a great concern as threats of service interruption, unauthorized access, stealing and altering of information, and spreading of viruses have become more prevalent and serious. Application layer access control of applications is a critical component in the overall security solution that also includes encryption, firewalls, virtual private networks, antivirus, and intrusion detection. An access control solution, based on an open-source access manager augmented with custom software components, was developed to provide protection to both Web-based and Javabased client and server applications. The DISA Security Service (DISA-SS) provides common access control capabilities for AMMOS software applications through a set of application programming interfaces (APIs) and network- accessible security services for authentication, single sign-on, authorization checking, and authorization policy management. The OpenAM access management technology designed for Web applications can be extended to meet the needs of Java thick clients and stand alone servers that are commonly used in the JPL AMMOS environment. The DISA-SS reusable components have greatly reduced the effort for each AMMOS subsystem to develop its own access control strategy. The novelty of this work is that it leverages an open-source access management product that was designed for Webbased applications to provide access control for Java thick clients and Java standalone servers. Thick clients and standalone servers are still commonly used in businesses and government, especially for applications that require rich graphical user interfaces and high-performance visualization that cannot be met by thin clients running on Web browsers

    DuPlain, Ron; Benson, John; Sessoms, Eric

    2008-08-01

    In late 2007, the National Radio Astronomy Observatory (NRAO) launched Data Vault, a feature-rich web application for simplified access to NRAO data archives. This application allows users to submit a Google-like free-text search, and browse, download, and view further information on matching telescope data. Data Vault uses the model-view-controller design pattern with web.py, a minimalist open-source web framework built with the Python Programming Language. Data Vault implements an Ajax client built on the Google Web Toolkit (GWT), which creates structured JavaScript applications. This application supports plug-ins for linking data to additional web tools and services, including Google Sky. NRAO sought the inspiration of Google's remarkably elegant user interface and notable performance to create a modern search tool for the NRAO science data archive, taking advantage of the rapid development frameworks of web.py and GWT to create a web application on a short timeline, while providing modular, easily maintainable code. Data Vault provides users with a NRAO-focused data archive while linking to and providing more information wherever possible. Free-text search capabilities are possible (and even simple) with an innovative query parser. NRAO develops all software under an open-source license; Data Vault is available to developers and users alike.

    Zietlow, D. W.; Molnar, C.; Meertens, C. M.; Phillips, D. A.; Bartel, B. A.; Ertz, D. J.

    2016-12-01

    UNAVCO, a university-governed consortium that enables geodetic research and education, is developing and implementing new web services to standardize and enhance access to geodetic data for an ever-growing community of users. This simple and easy to use tool gives both experienced and novice users access to all data and products archived at UNAVCO through a uniform interface regardless of data type and structure. UNAVCO data product types include GPS station position time series, velocity estimates and metadata, as well as meteorological time series, and borehole geophysical data and metadata including strain, seismic, and tilt time series. Users access data through a request URL or through the Swagger user interface (UI). The Swagger UI allows users to easily learn about the web services and provides users the ability to test the web services in their web browser. Swagger UI also provides documentation of the web services' URLs and query parameters. With this documentation users can see the valid query parameters for each web service to assist in documentation for both the developers and the users.Output from the web services is currently in a standard comma-separated (CSV) format that can then be used in other processing and/or visualization programs. The web services are being standardized so that all CSV formats will follow the GeoCSV specification. Other formats will be available such as GeoJSON and time series xml since not all data are well represented by the CSV format. The UNAVCO web services are written using Python along with the Flask microframework. This allows quick development and the ability to easily implement new services. Future services are being planned to allow users to access metadata from any station with data available directly or indirectly from the UNAVCO website. In collaboration with the UNAVCO Student Internship Program (USIP), we developed a short video demonstrating how to use the web services tool to assist new users and the broader

    Full Text Available The motive of this study is to suggest a protocol which can be implemented to observe the activities of any node within a network whose contribution to the organization needs to be measured. Many associates working in any organization misuse the resources allocated to them and waste their working time in unproductive work which is of no use to the organization. In order to tackle this problem the dynamic approach in monitoring web pages accessed by user using cookies gives a very efficient way of tracking all the activities of the individual and store in cookies which are generated based on their recent web activity and display a statistical information of how the users web activity for the time period has been utilized for every IP-address in the network. In a ever challenging dynamic world monitoring the productivity of the associates in the organization plays an utmost important role.

    2010-01-01

    It is now feasible to host basic web services on a smart phone due to the advances in wireless devices and mobile communication technologies. While the applications are quite welcoming, the ability to provide secure and reliable communication in the vulnerable and volatile mobile ad-hoc topologies is vastly becoming necessary. The paper mainly addresses the details and issues in providing secured communication and access control for the mobile web service provisioning domain. While the basic message-level security can be provided, providing proper access control mechanisms for the Mobile Host still poses a great challenge. This paper discusses details of secure communication and proposes the distributed semantics-based authorization mechanism.

  5. Open Access Scholarly Publications as OER

    2013-06-01

    Full Text Available This paper presents the rationale, common practices, challenges, and some personal anecdotes from a journal editor on the production, use, and re-use of peer-reviewed scholarly articles as open educational resources (OER. The scholarly and professional discourse related to open educational resources has largely focused on open learning objects, courseware, and textbooks. However, especially in graduate education, articles published in scholarly journals are often a major component of the course content in formal education. In addition, open access journal articles are critical to expanding access to knowledge by scholars in the developing world and in fostering citizen science, by which everyone has access to the latest academic information and research results. In this article, I highlight some of the challenges, economic models, and evidence for quality of open access journal content and look at new affordances provided by the Net for enhanced functionality, access, and distribution.In the 17 years since I graduated with a doctorate degree, the climate and acceptance of open access publishing has almost reversed itself. I recall a conversation with my PhD supervisor in which he argued that publishing online was not a viable option as the product would not have permanency, scholarly recognition, or the prestige of a paper publication. His comments reflect the confusion between online resources and those described as open access, but as well illustrate the change in academic acceptance and use of open access products during the past decade. The evolution from paper to online production and consumption is a disruptive technology in which much lower cost and increased accessibility of online work opens the product to a completely new group of potential users. In the case of OER these consumers are primarily students, but certainly access to scholars from all parts of the globe and the availability to support citizen science (Silvertown, 2009

  8. Authentication and Access: Accommodating Public Users in an Academic World

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available In the fall of 2004, the Academic Computing Center, a division of the Information Technology Services Department (ITS at Minnesota State University, Mankato took over responsibility for the computers in the public areas of Memorial Library. For the first time, affiliated Memorial Library users were required to authenticate using a campus username and password, a change that effectively eliminated computer access for anyone not part of the university community. This posed a dilemma for the librarians. Because of its Federal Depository status, the library had a responsibility to provide general access to both print and online government publications for the general public. Furthermore, the library had a long tradition of providing guest access to most library resources, and there was reluctance to abandon the practice. Therefore the librarians worked with ITS to retain a small group of six computers that did not require authentication and were clearly marked for community use, along with several standup, open-access computers on each floor used primarily for searching the library catalog. The additional need to provide computer access to high school students visiting the library for research and instruction led to more discussions with ITS and resulted in a means of generating temporary usernames and passwords through a Web form. These user accommodations were implemented in the library without creating a written policy governing the use of open-access computers.

    2015-08-01

    Full Text Available Definitely, the WWW and ICTs have become the preferred media for the interaction between society and its citizens, and public and private organizations have today the possibility of deploying their activities through the Web. In particular, university education is a domain where the benefits of these technological resources can strongly contribute in caring for students. However, most university Web portals are inaccessible to their user community (students, professors, and non-teaching staff, between others, since these portals do not take into account the needs of people with different capabilities. In this work, we propose an accessibility pattern driven process to the redesign of university Web portals, aiming to break down barriers for visually impaired users. The approach is implemented to a real case study: the Web portal of Universidad Nacional de la Patagonia Austral (UNPA. The results come from applying accessibility recommendations and evaluation tools (automatic and manual from internationally recognized organizations, to both versions of the Web portal: the original and the redesign one.

    Sexual health service access is fundamental to good sexual health, yet interventions designed to address this have rarely been implemented or evaluated. In this article, pilot evaluation findings for a targeted public health behavior change intervention, delivered via a website and web-app, aiming to increase uptake of sexual health services among 13-19-year olds are reported. A pre-post questionnaire-based design was used. Matched baseline and follow-up data were identified from 148 respondents aged 13-18 years. Outcome measures were self-reported service access, self-reported intention to access services and beliefs about services and service access identified through needs analysis. Objective service access data provided by local sexual health services were also analyzed. Analysis suggests the intervention had a significant positive effect on psychological barriers to and antecedents of service access among females. Males, who reported greater confidence in service access compared with females, significantly increased service access by time 2 follow-up. Available objective service access data support the assertion that the intervention may have led to increases in service access. There is real promise for this novel digital intervention. Further evaluation is planned as the model is licensed to and rolled out by other local authorities in the United Kingdom.

    Full Text Available Objective: This study analyzed issues regarding accessibility in cultural facilities and aimed to analyze accessibility in the municipal cultural institutions and two districts of São Paulo state. Method: All cultural buildings were visited and, using a checklist based on the Brazilian Association of Technical Standards (NBR 9050, 2004, the public spaces were classed as adequate or inadequate with respect to their accessibility to people with a visual and physical disability. The data collected was subjected to descriptive analysis by scoring the most common accessibility resources, their adequacy as well as the resources not installed. Results: The results show that all the external and internal areas of the analyzed buildings need for adaptations, installations or the building of equipment that allows the physically or visually disabled to interact with the environment in the chosen cultural spaces. The work showed that the best evaluated item were the ramps and the worst was the tactile map, absent in all buildings. Conclusion: The data show the “state of the art” in the chosen city and discussed the difficulties in the implementation of Brazilian Association of Technical standards, both in construction and in the adaptations, pointing new accessibility concerns on the studied cities.

    Full Text Available Web Geographic Information System (Web GIS has been extensively and successfully exploited in various arenas. However, to date, the application of this technology in public health surveillance has yet to be systematically explored in the Web 2.0 era. We reviewed existing Web GIS-based Public Health Surveillance Systems (WGPHSSs and assessed them based on 20 indicators adapted from previous studies. The indicators comprehensively cover various aspects of WGPHSS development, including metadata, data, cartography, data analysis, and technical aspects. Our literature search identified 58 relevant journal articles and 27 eligible WGPHSSs. Analyses of results revealed that WGPHSSs were frequently used for infectious-disease surveillance, and that geographical and performance inequalities existed in their development. The latest Web and Web GIS technologies have been used in developing WGPHSSs; however, significant deficiencies in data analysis, system compatibility, maintenance, and accessibility exist. A balance between public health surveillance and privacy concerns has yet to be struck. Use of news and social media as well as Web-user searching records as data sources, participatory public health surveillance, collaborations among health sectors at different spatial levels and among various disciplines, adaption or reuse of existing WGPHSSs, and adoption of geomashup and open-source development models were identified as the directions for advancing WGPHSSs.

    2005-01-01

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

    2016-01-01

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

  20. PUBLIC ACCESS TO PRIVATE LAND IN SCOTLAND

    Directory of Open Access Journals (Sweden)

    David L Carey Miller

    2012-08-01

    Full Text Available This article attempts to understand the radical reform of Scottish land law in its provision for a general right of public access to private land introduced in 2003 as part of land reform legislation, an important aspect of the initial agenda of the Scottish Parliament revived in 1999. The right is to recreational access for a limited period and the right to cross land. Access can be taken only on foot or by horse or bicycle. As a starting point clarification of the misunderstood pre-reform position is attempted. The essential point is that Scots common law does not give civil damages for a simple act of trespass (as English law does but only a right to obtain removal of the trespasser. Under the reforms the longstanding Scottish position of landowners allowing walkers access to the hills and mountains becomes a legal right. A critical aspect of the new right is that it is one of responsible access; provided a landowner co-operates with the spirit and system of the Act access can be denied on the basis that it is not being exercised responsibly. But the onus is on the landowner to show that the exercise of the right is not responsible.Although the right applies to all land a general exception protects the privacy of a domestic dwelling. Early case law suggests that the scope of this limit depends upon particular circumstances although reasonable 'garden ground' is likely to be protected. There are various particular limits such as school land.Compliance with the protection of property under the European Convention on Human Rights is discussed. The article emphasises the latitude, open to nations, for limitations to the right of ownership in land in the public interest. The extent of the Scottish access inroad illustrates this. This leads to the conclusion that 'land governance' – the subject of the Potchefstroom Conference at which the paper was initially presented – largely remains a matter for domestic law; the lex situs concept is alive

  1. SalanderMaps: A rapid overview about felt earthquakes through data mining of web-accesses

    Science.gov (United States)

    Kradolfer, Urs

    2013-04-01

    While seismological observatories detect and locate earthquakes based on measurements of the ground motion, they neither know a priori whether an earthquake has been felt by the public nor is it known, where it has been felt. Such information is usually gathered by evaluating feedback reported by the public through on-line forms on the web. However, after a felt earthquake in Switzerland, many people visit the webpages of the Swiss Seismological Service (SED) at the ETH Zurich and each such visit leaves traces in the logfiles on our web-servers. Data mining techniques, applied to these logfiles and mining publicly available data bases on the internet open possibilities to obtain previously unknown information about our virtual visitors. In order to provide precise information to authorities and the media, it would be desirable to rapidly know from which locations these web-accesses origin. The method 'Salander' (Seismic Activitiy Linked to Area codes - Nimble Detection of Earthquake Rumbles) will be introduced and it will be explained, how the IP-addresses (each computer or router directly connected to the internet has a unique IP-address; an example would be 129.132.53.5) of a sufficient amount of our virtual visitors were linked to their geographical area. This allows us to unprecedentedly quickly know whether and where an earthquake was felt in Switzerland. It will also be explained, why the method Salander is superior to commercial so-called geolocation products. The corresponding products of the Salander method, animated SalanderMaps, which are routinely generated after each earthquake with a magnitude of M>2 in Switzerland (http://www.seismo.ethz.ch/prod/salandermaps/, available after March 2013), demonstrate how the wavefield of earthquakes propagates through Switzerland and where it was felt. Often, such information is available within less than 60 seconds after origin time, and we always get a clear picture within already five minutes after origin time

    Full Text Available Web logs are a young and dynamic media type. Due to the intrinsic relationship among Web objects and the deficiency of a uniform schema of web documents, Web community mining has become significant area for Web data management and analysis. The research of Web communities extents a number of research domains. In this paper an ontological model has been present with some recent studies on this topic, which cover finding relevant Web pages based on linkage information, discovering user access patterns through analyzing Web log files from Web data. A simulation has been created with the academic website crawled data. The simulation is done in JAVA and ORACLE environment. Results show that prediction of user session could give us plenty of vital information for the Business Intelligence.

    Public access computing in health science libraries began with online computer-assisted instruction. Library-based collections and services have expanded with advances in microcomputing hardware and software. This growth presents problems: copyright, quality, instability in the publishing industry, and uncertainty about collection scope; librarians managing the new services require new skills to support their collections. Many find the cooperative efforts of several organizational units are required. Current trends in technology for the purpose of information management indicate that these services will continue to be a significant focus for libraries.

  4. Public Access to NASA's Earth Science Data

    Many steps have been taken over the past 20 years to make NASA's Earth Science data more accessible to the public. The data collected by NASA represent a significant public investment in research. NASA holds these data in a public trust to promote comprehensive, long-term Earth science research. Consequently, NASA developed a free, open and non-discriminatory policy consistent with existing international policies to maximize access to data and to keep user costs as low as possible. These policies apply to all data archived, maintained, distributed or produced by NASA data systems. The Earth Observing System Data and Information System (EOSDIS) is a major core capability within NASA Earth Science Data System Program. EOSDIS is designed to ingest, process, archive, and distribute data from approximately 90 instruments. Today over 6800 data products are available to the public through the EOSDIS. Last year, EOSDIS distributed over 636 million science data products to the user community, serving over 1.5 million distinct users. The system supports a variety of science disciplines including polar processes, land cover change, radiation budget, and most especially global climate change. A core philosophy of EOSDIS is that the general user is best served by providing discipline specific support for the data. To this end, EOSDIS has collocated NASA Earth science data with centers of science discipline expertise, called Distributed Active Archive Centers (DAACs). DAACs are responsible for data management, archive and distribution of data products. There are currently twelve DAACs in the EOSDIS system. The centralized entrance point to the NASA Earth Science data collection can be found at http://earthdata.nasa.gov. Over the years, we have developed several methods for determining needs of the user community including use of the American Customer Satisfaction Index survey and a broad metrics program. Annually, we work with an independent organization (CFI Group) to send this

    1995-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer and technology awareness applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology OPportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. The NASA Technical Report Server (NTRS) provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people.

Easily extendible both in terms of new classes as well as the new language this method proves to be a good solution for text classification faced with the total lack of training data. To evaluate the proposed solution we have used a small collection of public health related web pages created by a double blind manual classification. Our experiments have shown that by choosing the adequate threshold value the desired value for either precision or recall can be achieved.

    2014-01-01

    The number of scholarly documents available on the web is estimated using capture/recapture methods by studying the coverage of two major academic search engines: Google Scholar and Microsoft Academic Search. Our estimates show that at least 114 million English-language scholarly documents are accessible on the web, of which Google Scholar has nearly 100 million. Of these, we estimate that at least 27 million (24%) are freely available since they do not require a subscription or payment of any kind. In addition, at a finer scale, we also estimate the number of scholarly documents on the web for fifteen fields: Agricultural Science, Arts and Humanities, Biology, Chemistry, Computer Science, Economics and Business, Engineering, Environmental Sciences, Geosciences, Material Science, Mathematics, Medicine, Physics, Social Sciences, and Multidisciplinary, as defined by Microsoft Academic Search. In addition, we show that among these fields the percentage of documents defined as freely available varies significantly, i.e., from 12 to 50%.

    Mirri, Silvia; Salomoni, Paola; Prandi, Catia; Muratori, Ludovico Antonio

    2012-09-01

    The Web 2.0 evolution has spread more interactive technologies which affected accessibility for users who navigate the Web by using assistive technologies. In particular, the partial download of new data, the continuous refreshing, and the massive use of scripting can represent significant barriers especially for people with visual impairments, who enjoy the Web by means of screen readers. On the other hand, such technologies can be an opportunity, because they can provide a new means of transcoding Web content, making the Web more accessible. In this article we present GAPforAPE, an augmented browsing system (based on Web browsers extensions) which offers a user's profiling system and transcodes Web content according to constrains declared by users: the same Web page is provided to any user, but GAPforAPE computes adequate customizations, by exploiting scripting technologies which usually affect Web pages accessibility. GAPforAPE imitates screen readers behavior: it applies a specific set of transcoding scripts devoted to a given Web site, when available, and a default set of transcoding operations otherwise. The continuous and quick evolution of the Web has shown that a crowdsourcing system is a desirable solution, letting the transcoding scripts evolve in the same way.

  10. Resolving the problem of multiple accessions of the same transcript deposited across various public databases.

    Science.gov (United States)

    Weirick, Tyler; John, David; Uchida, Shizuka

    2017-03-01

    Maintaining the consistency of genomic annotations is an increasingly complex task because of the iterative and dynamic nature of assembly and annotation, growing numbers of biological databases and insufficient integration of annotations across databases. As information exchange among databases is poor, a 'novel' sequence from one reference annotation could be annotated in another. Furthermore, relationships to nearby or overlapping annotated transcripts are even more complicated when using different genome assemblies. To better understand these problems, we surveyed current and previous versions of genomic assemblies and annotations across a number of public databases containing long noncoding RNA. We identified numerous discrepancies of transcripts regarding their genomic locations, transcript lengths and identifiers. Further investigation showed that the positional differences between reference annotations of essentially the same transcript could lead to differences in its measured expression at the RNA level. To aid in resolving these problems, we present the algorithm 'Universal Genomic Accession Hash (UGAHash)' and created an open source web tool to encourage the usage of the UGAHash algorithm. The UGAHash web tool (http://ugahash.uni-frankfurt.de) can be accessed freely without registration. The web tool allows researchers to generate Universal Genomic Accessions for genomic features or to explore annotations deposited in the public databases of the past and present versions. We anticipate that the UGAHash web tool will be a valuable tool to check for the existence of transcripts before judging the newly discovered transcripts as novel. © The Author 2016.

    2016-08-01

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

  12. Heterogeneity of publicly accessible online critical values for therapeutic drugs

    Directory of Open Access Journals (Sweden)

    Colt M McClain

    2011-01-01

    Full Text Available Introduction: Critical values are reported to clinicians when laboratory values are life threatening and require immediate attention. To date no definitive critical value limit recommendations have been produced regarding therapeutic drug monitoring. Some laboratories choose to publish critical value lists online. These publicly available values may be accessed and potentially utilized by laboratory staff, patient care providers, and patients. Materials and Methods: A web-based search of laboratories associated with the Accreditation Council for Graduate Medical Education pathology residency programs was initiated to determine which therapeutic drugs had critical values and to examine the degree of variation in published critical values for these institutions. Results: Of the 107 institutions with university-based pathology training programs, 36 had published critical values online for review. Thirteen therapeutic drugs were investigated and the number of institutions reporting critical value limits for the drug, as well as the median, range, standard deviation, and the coefficient of variation of critical value concentration limits for each drug were determined. A number of the online critical value limits were deemed to be erroneous, most likely due to incorrectly listed units of measurement. Conclusions: There was a large degree of heterogeneity with regard to the chosen critical value limits for therapeutic drugs. This wide variance in critical values appears to be greater than that observed in interassay proficiency testing. Institutions should reexamine the rationale for their current critical value parameters and ensure that critical value limits and associated units are accurately published online.

    The blockage of the hERG K(+) channels is closely associated with lethal cardiac arrhythmia. The notorious ligand promiscuity of this channel earmarked hERG as one of the most important antitargets to be considered in early stages of drug development process. Herein we report on the development of an innovative and freely accessible web server for early identification of putative hERG blockers and non-blockers in chemical libraries. We have collected the largest publicly available curated hERG dataset of 5,984 compounds. We succeed in developing robust and externally predictive binary (CCR≈0.8) and multiclass models (accuracy≈0.7). These models are available as a web-service freely available for public at http://labmol.farmacia.ufg.br/predherg/. Three following outcomes are available for the users: prediction by binary model, prediction by multi-class model, and the probability maps of atomic contribution. The Pred-hERG will be continuously updated and upgraded as new information became available. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2000-05-01

    The World Wide Web has provided the public with easy and affordable access to a vast range of information. However, claims may be unsubstantiated and misleading. The purpose of this study was to use cutaneous laser surgery as a model to assess the availability and reliability of Web sites and to evaluate this resource for the quality of patient and provider education. Three commercial methods of searching the Internet were used, identifying nearly 500,000 possible sites. The first 100 sites listed by each search engine (a total of 300 sites) were compared. Of these, 126 were listed repeatedly within a given retrieval method, whereas only 3 sites were identified by all 3 search engines. After elimination of duplicates, 40 sites were evaluated for content and currency of information. The most common features included postoperative care suggestions, options for pain management or anesthesia, a description of the way in which lasers work, and the types of lasers used for different procedures. Potential contraindications to laser procedures were described on fewer than 30% of the sites reviewed. None of the sites contained substantiation of claims or referrals to peer-reviewed publications or research. Because of duplication and the prioritization systems of search engines, the ease of finding sites did not correlate with the quality of the site's content. Our findings show that advertisements for services exceed useful information.

  6. Improving access to space weather data via workflows and web services

    Science.gov (United States)

    Sundaravel, Anu Swapna

    The Space Physics Interactive Data Resource (SPIDR) is a web-based interactive tool developed by NOAA's National Geophysical Data Center to provide access to historical space physics datasets. These data sets are widely used by physicists for space weather modeling and predictions. Built on a distributed network of databases and application servers, SPIDR offers services in two ways: via a web page interface and via a web service interface. SPIDR exposes several SOAP-based web services that client applications implement to connect to a number of data sources for data download and processing. At present, the usage of the web services has been difficult, adding unnecessary complexity to client applications and inconvenience to the scientists who want to use these datasets. The purpose of this study focuses on improving SPIDR's web interface to better support data access, integration and display. This is accomplished in two ways: (1) examining the needs of scientists to better understand what web services they require to better access and process these datasets and (2) developing a client application to support SPIDR's SOAP-based services using the Kepler scientific workflow system. To this end, we identified, designed and developed several web services for filtering the existing datasets and created several Kepler workflows to automate routine tasks associated with these datasets. These workflows are a part of the custom NGDC build of the Kepler tool. Scientists are already familiar with Kepler due to its extensive use in this domain. As a result, this approach provides them with tools that are less daunting than raw web services and ultimately more useful and customizable. We evaluated our work by interviewing various scientists who make use of SPIDR and having them use the developed Kepler workflows while recording their feedback and suggestions. Our work has improved SPIDR such that new web services are now available and scientists have access to a desktop

    2017-04-01

    The accessibility to environmental information via web viewers using map services (OGC or proprietary services) has become more frequent since newly information sources (ortophotos, LIDAR, GPS) are of great detailed and thus generate a great volume of data which barely can be disseminated using either analogue (paper maps) or digital (pdf) formats. Moreover, governments and public institutions are concerned about the need of facilitates provision to research results and improve communication about natural hazards to citizens and stakeholders. This information ultimately, if adequately disseminated, it's crucial in decision making processes, risk management approaches and could help to increase social awareness related to environmental issues (particularly climate change impacts). To overcome this issue, two strategies for wide dissemination and communication of the results achieved in the calculation of beach erosion for the 640 km length of the Andalusian coast (South Spain) using web viewer technology are presented. Each of them are oriented to different end users and thus based on different methodologies. Erosion rates has been calculated at 50m intervals for different periods (1956-1977-2001-2011) as part of a National Research Project based on the spasialisation and web-access of coastal vulnerability indicators for Andalusian region. The 1st proposal generates WMS services (following OGC standards) that are made available by Geoserver, using a geoviewer client developed through Leaflet. This viewer is designed to be used by the general public (citizens, politics, etc) by combining a set of tools that give access to related documents (pdfs), visualisation tools (panoramio pictures, geo-localisation with GPS) are which are displayed within an user-friendly interface. Further, the use of WMS services (implemented on Geoserver) provides a detailed semiology (arrows and proportional symbols, using alongshore coastaline buffers to represent data) which not only

    Georgiev, Martin; Jana, Suman; Shmatikov, Vitaly

    2014-02-01

    Hybrid mobile applications (apps) combine the features of Web applications and "native" mobile apps. Like Web applications, they are implemented in portable, platform-independent languages such as HTML and JavaScript. Like native apps, they have direct access to local device resources-file system, location, camera, contacts, etc. Hybrid apps are typically developed using hybrid application frameworks such as PhoneGap. The purpose of the framework is twofold. First, it provides an embedded Web browser (for example, WebView on Android) that executes the app's Web code. Second, it supplies "bridges" that allow Web code to escape the browser and access local resources on the device. We analyze the software stack created by hybrid frameworks and demonstrate that it does not properly compose the access-control policies governing Web code and local code, respectively. Web code is governed by the same origin policy, whereas local code is governed by the access-control policy of the operating system (for example, user-granted permissions in Android). The bridges added by the framework to the browser have the same local access rights as the entire application, but are not correctly protected by the same origin policy. This opens the door to fracking attacks, which allow foreign-origin Web content included into a hybrid app (e.g., ads confined in iframes) to drill through the layers and directly access device resources. Fracking vulnerabilities are generic: they affect all hybrid frameworks, all embedded Web browsers, all bridge mechanisms, and all platforms on which these frameworks are deployed. We study the prevalence of fracking vulnerabilities in free Android apps based on the PhoneGap framework. Each vulnerability exposes sensitive local resources-the ability to read and write contacts list, local files, etc.-to dozens of potentially malicious Web domains. We also analyze the defenses deployed by hybrid frameworks to prevent resource access by foreign-origin Web content

    Full Text Available Due to the significant increase in threats, attacks and vulnerabilities that affect the Web in recent years has resulted the development and implementation of pools and methods to ensure security measures in the privacy, confidentiality and data integrity of users and businesses. Under certain circumstances, despite the implementation of these tools do not always get the flow of information which is passed in a secure manner. Many of these security tools and methods cannot be accessed by people who have disabilities or assistive technologies which enable people to access the Web efficiently. Among these security tools that are not accessible are the virtual keyboard, the CAPTCHA and other technologies that help to some extent to ensure safety on the Internet and are used in certain measures to combat malicious code and attacks that have been increased in recent times on the Web. Through the implementation of intelligent systems can detect, recover and receive information on the characteristics and properties of the different tools and hardware devices or software with which the user is accessing a web application and through analysis and interpretation of these intelligent systems can infer and automatically adjust the characteristics necessary to have these tools to be accessible by anyone regardless of disability or navigation context. This paper defines a set of guidelines and specific features that should have the security tools and methods to ensure the Web accessibility through the implementation of intelligent systems.

    Digital imaging and communications in medicine (DICOM) 3.0 standard provides the baseline for the picture archiving and communication systems (PACS). The development of Internet and various communication media initiated demand for non-DICOM access to PACS systems. Ever-increasing utilization of the web browsers, laptops and handheld devices, as opposed to desktop applications and static organizational computers, lead to development of different web technologies. The DICOM standard officials accepted those subsequently as tools of alternative access. This paper provides an overview of the current state of development of the web access technology to the DICOM repositories. It presents a different approach of using HTML5 features of the web browsers through the JavaScript language and the WebSocket protocol by enabling real-time communication with DICOM repositories. JavaScript DICOM network library, DICOM to WebSocket proxy and a proof-of-concept web application that qualifies as a DICOM 3.0 device were developed.

    Regional networking between services that provide mental health care in Brazil's decentralized public health system is challenging, partly due to the simultaneous existence of services managed by municipal and state authorities and a lack of efficient and transparent mechanisms for continuous and updated communication between them. Since 2011, the Ribeirao Preto Medical School and the XIII Regional Health Department of the Sao Paulo state, Brazil, have been developing and implementing a web-based information system to facilitate an integrated care throughout a public regional mental health care network. After a profound on-site analysis, the structure of the network was identified and a web-based information system for psychiatric admissions and discharges was developed and implemented using a socio-technical approach. An information technology team liaised with mental health professionals, health-service managers, municipal and state health secretariats and judicial authorities. Primary care, specialized community services, general emergency and psychiatric wards services, that comprise the regional mental healthcare network, were identified and the system flow was delineated. The web-based system overcame the fragmentation of the healthcare system and addressed service specific needs, enabling: detailed patient information sharing; active coordination of the processes of psychiatric admissions and discharges; real-time monitoring; the patients' status reports; the evaluation of the performance of each service and the whole network. During a 2-year period of operation, it registered 137 services, 480 health care professionals and 4271 patients, with a mean number of 2835 accesses per month. To date the system is successfully operating and further expanding. We have successfully developed and implemented an acceptable, useful and transparent web-based information system for a regional mental healthcare service network in a medium-income country with a decentralized

    Full Text Available Abstract Background Surveillance data allow for analysis, providing public health officials and policy-makers with a basis for long-term priorities and timely information on possible outbreaks for rapid response (data for action. In this article we describe the considerations and technology behind a newly introduced public web tool in Sweden for easy retrieval of county and national surveillance data on communicable diseases. Methods The web service was designed to automatically present updated surveillance statistics of some 50 statutory notifiable diseases notified to the Swedish Institute for Infectious Disease Control (SMI. The surveillance data is based on clinical notifications from the physician having treated the patient and laboratory notifications, merged into cases using a unique personal identification number issued to all Swedish residents. The web service use notification data from 1997 onwards, stored in a relational database at the SMI. Results The web service presents surveillance data to the user in various ways; tabulated data containing yearly and monthly disease data per county, age and sex distribution, interactive maps illustrating the total number of cases and the incidence per county and time period, graphs showing the total number of cases per week and graphs illustrating trends in the disease data. The system design encompasses the database (storing the data, the web server (holding the web service and an in-the-middle computer (to ensure good security standards. Conclusions The web service has provided the health community, the media, and the public with easy access to both timely and detailed surveillance data presented in various forms. Since it was introduced in May 2003, the system has been accessed more than 1,000,000 times, by more than 10,000 different viewers (over 12.600 unique IP-numbers.

  18. Assessment method of accessibility conditions: how to make public buildings accessible?

    Science.gov (United States)

    Andrade, Isabela Fernandes; Ely, e Vera Helena Moro Bins

    2012-01-01

    The enforcement of accessibility today has faced several difficulties, such as intervention in historic buildings that now house public services and cultural activities, such as town halls, museums and theaters and should allow access, on equal terms to all people. The paper presents the application of a method for evaluating the spatial accessibility conditions and their results. For this, we sought to support the theoretical foundation about the main issue involved and legislation. From the method used--guided walks--it was possible to identify the main barriers to accessibility in historic buildings. From the identified barriers, possible solutions are presented according to the four components of accessibility: spatial orientation, displacement, use and communication. It is hoped also that the knowledge gained in this research contributes to an improvement of accessibility legislation in relation to the listed items.

    Full Text Available As the internet is fast migrating from static web pages to dynamic web pages, the users with visual impairment find it confusing and challenging when accessing the contents on the web. There is evidence that dynamic web applications pose accessibility challenges for the visually impaired users. This study shows that a difference can be made through the basic understanding of the technical requirement of users with visual impairment and addresses a number of issues pertinent to the accessibility needs for such users. We propose that only by designing a framework that is structurally flexible, by removing unnecessary extras and thereby making every bit useful (fit-for-purpose, will visually impaired users be given an increased capacity to intuitively access e-contents. This theory is implemented in a dynamic website for the visually impaired designed in this study. Designers should be aware of how the screen reading software works to enable them make reasonable adjustments or provide alternative content that still corresponds to the objective content to increase the possibility of offering faultless service to such users. The result of our research reveals that materials can be added to a content repository or re-used from existing ones by identifying the content types and then transforming them into a flexible and accessible one that fits the requirements of the visually impaired through our method (no-frill + agile methodology rather than computing in advance or designing according to a given specification.

    We propose an efficient hybrid algorithm WDHP in this paper for mining frequent access patterns.WDHP adopts the techniques of DHP to optimize its performance, which is using hash table to filter candidate set and trimming database.Whenever the database is trimmed to a size less than a specified threshold, the algorithm puts the database into main memory by constructing a tree, and finds frequent patterns on the tree.The experiment shows that WDHP outperform algorithm DHP and main memory based algorithm WAP in execution efficiency.

  5. Government databases and public health research: facilitating access in the public interest.

    Science.gov (United States)

    Adams, Carolyn; Allen, Judy

    2014-06-01

    Access to datasets of personal health information held by government agencies is essential to support public health research and to promote evidence-based public health policy development. Privacy legislation in Australia allows the use and disclosure of such information for public health research. However, access is not always forthcoming in a timely manner and the decision-making process undertaken by government data custodians is not always transparent. Given the public benefit in research using these health information datasets, this article suggests that it is time to recognise a right of access for approved research and that the decisions, and decision-making processes, of government data custodians should be subject to increased scrutiny. The article concludes that researchers should have an avenue of external review where access to information has been denied or unduly delayed.

  6. Cloud-based Web Services for Near-Real-Time Web access to NPP Satellite Imagery and other Data

    Science.gov (United States)

    Evans, J. D.; Valente, E. G.

    2010-12-01

    We are building a scalable, cloud computing-based infrastructure for Web access to near-real-time data products synthesized from the U.S. National Polar-Orbiting Environmental Satellite System (NPOESS) Preparatory Project (NPP) and other geospatial and meteorological data. Given recent and ongoing changes in the the NPP and NPOESS programs (now Joint Polar Satellite System), the need for timely delivery of NPP data is urgent. We propose an alternative to a traditional, centralized ground segment, using distributed Direct Broadcast facilities linked to industry-standard Web services by a streamlined processing chain running in a scalable cloud computing environment. Our processing chain, currently implemented on Amazon.com's Elastic Compute Cloud (EC2), retrieves raw data from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and synthesizes data products such as Sea-Surface Temperature, Vegetation Indices, etc. The cloud computing approach lets us grow and shrink computing resources to meet large and rapid fluctuations (twice daily) in both end-user demand and data availability from polar-orbiting sensors. Early prototypes have delivered various data products to end-users with latencies between 6 and 32 minutes. We have begun to replicate machine instances in the cloud, so as to reduce latency and maintain near-real time data access regardless of increased data input rates or user demand -- all at quite moderate monthly costs. Our service-based approach (in which users invoke software processes on a Web-accessible server) facilitates access into datasets of arbitrary size and resolution, and allows users to request and receive tailored and composite (e.g., false-color multiband) products on demand. To facilitate broad impact and adoption of our technology, we have emphasized open, industry-standard software interfaces and open source software. Through our work, we envision the widespread establishment of similar, derived, or interoperable systems for

  7. Does the public deserve free access to climate system science?

    Science.gov (United States)

    Grigorov, Ivo

    2010-05-01

    Some time ago it was the lack of public access to medical research data that really stirred the issue and gave inertia for legislation and a new publishing model that puts tax payer-funded medical research in the hands of those who fund it. In today's age global climate change has become the biggest socio-economic challenge, and the same argument resonates: climate affects us all and the publicly-funded science quantifying it should be freely accessible to all stakeholders beyond academic research. Over the last few years the ‘Open Access' movement to remove as much as possible subscription, and other on-campus barriers to academic research has rapidly gathered pace, but despite significant progress, the climate system sciences are not among the leaders in providing full access to their publications and data. Beyond the ethical argument, there are proven and tangible benefits for the next generation of climate researchers to adapt the way their output is published. Through the means provided by ‘open access', both data and ideas can gain more visibility, use and citations for the authors, but also result in a more rapid exchange of knowledge and ideas, and ultimately progress towards a sought solution. The presentation will aim to stimulate discussion and seek progress on the following questions: Should free access to climate research (& data) be mandatory? What are the career benefits of using ‘open access' for young scientists? What means and methods should, or could, be incorporated into current European graduate training programmes in climate research, and possible ways forward?

  12. Unequal access to public healthcare facilities: theory and measurement revisited

    Directory of Open Access Journals (Sweden)

    Stefano Mainardi

    2007-12-01

    Full Text Available Adequate coverage and efficiency of public health services are high priorities for sustainable growth and development. In many countries, public healthcare continues to fall short of demand, and remains unevenly distributed among the population. As in other areas of project appraisal, studies on social equity and access to public utilities are fraught with theoretical and empirical questions. Based on the concepts of marginal disutility with respect to distance, safety thresholds and `equally distributed equivalent' distance, the paper first reassesses utility theory assumptions supporting the rationale for functional re-specifications. Partly drawing on these theoretical refinements, the analysis formulates a stochastic cost frontier hurdle model with an endogenously determined hospital distance threshold. For illustrative purposes, this model is applied to pooled biennial communal data for Chile. Healthcare accessibility in terms of travel cost/time is proxied by distances of administrative centres from the nearest emergency hospitals over the period 2000-2003.

    2011-12-01

    The IRIS Data Management Center (DMC) has developed a suite of web services that provide access to the DMC's time series holdings, their related metadata and earthquake catalogs. In addition, services are available to perform simple, on-demand time series processing at the DMC prior to being shipped to the user. The primary goal is to provide programmatic access to data and processing services in a manner usable by and useful to the research community. The web services are relatively simple to understand and use and will form the foundation on which future DMC access tools will be built. Based on standard Web technologies they can be accessed programmatically with a wide range of programming languages (e.g. Perl, Python, Java), command line utilities such as wget and curl or with any web browser. We anticipate these services being used for everything from simple command line access, used in shell scripts and higher programming languages to being integrated within complex data processing software. In addition to improving access to our data by the seismological community the web services will also make our data more accessible to other disciplines. The web services available from the DMC include ws-bulkdataselect for the retrieval of large volumes of miniSEED data, ws-timeseries for the retrieval of individual segments of time series data in a variety of formats (miniSEED, SAC, ASCII, audio WAVE, and PNG plots) with optional signal processing, ws-station for station metadata in StationXML format, ws-resp for the retrieval of instrument response in RESP format, ws-sacpz for the retrieval of sensor response in the SAC poles and zeros convention and ws-event for the retrieval of earthquake catalogs. To make the services even easier to use, the DMC is developing a library that allows Java programmers to seamlessly retrieve and integrate DMC information into their own programs. The library will handle all aspects of dealing with the services and will parse the returned

    2007-12-01

    Full Text Available Abstract Background Large molecular sequence databases are fundamental resources for modern bioscientists. Whether for project-specific purposes or sharing data with colleagues, it is often advantageous to maintain smaller sequence databases. However, this is usually not an easy task for the average bench scientist. Results We present the Personal Sequence Database (PSD, a suite of tools to create and maintain small- to medium-sized web-accessible sequence databases. All interactions with PSD tools occur via the internet with a web browser. Users may define sequence groups within their database that can be maintained privately or published to the web for public use. A sequence group can be downloaded, browsed, searched by keyword or searched for sequence similarities using BLAST. Publishing a sequence group extends these capabilities to colleagues and collaborators. In addition to being able to manage their own sequence databases, users can enroll sequences in BLASTAgent, a BLAST hit tracking system, to monitor NCBI databases for new entries displaying a specified level of nucleotide or amino acid similarity. Conclusion The PSD offers a valuable set of resources unavailable elsewhere. In addition to managing sequence data and BLAST search results, it facilitates data sharing with colleagues, collaborators and public users. The PSD is hosted by the authors and is available at http://bioinfo.cgrb.oregonstate.edu/psd/.

  20. Public access to community documents: a fundamental human right?

    Directory of Open Access Journals (Sweden)

    Roy W. Davis

    1999-07-01

    Full Text Available There is a marked difference between the culture of open government in some Member States, particularly Sweden, and the culture of secrecy in Britain. Recent calls for a uniform interpretation of the law regarding public access to documents held by the Community Institutions seem to suggest that a Swedish-style right of access should be adopted at EU level, on the grounds that public access to government-held information is a fundamental human right. To date, however, it seems that insufficient arguments have been advanced in order to justify this particular claim. Notable constitutional lawyers remain sceptical, as do some Member State governments. Furthermore, in the absence of a convincing philosophical justification for the claim, a situation may be created in which certain people are said to enjoy a fundamental human right, not because they are human beings, but by virtue of their status as citizens or residents of an EU Member State. This appears to be counter-intuitive, if it is accepted that fundamental human rights should be enjoyed by all and should therefore be justified on the basis of universally-shared fundamental values. It therefore seems that further explanation of the importance of public access to documents is required, and further justification of the claim that this is, or should be regarded as, a fundamental human right.

    One of the biggest obstacles for the average Earth science student today is locating and obtaining satellite-based remote sensing data sets in a format that is accessible and optimal for their data analysis needs. At the Goddard Earth Sciences Data and Information Services Center (GES-DISC) alone, on the order of hundreds of Terabytes of data are available for distribution to scientists, students and the general public. The single biggest and time-consuming hurdle for most students when they begin their study of the various datasets is how to slog through this mountain of data to arrive at a properly sub-setted and manageable data set to answer their science question(s). The GES DISC provides a number of tools for data access and visualization, including the Google-like Mirador search engine and the powerful GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure (Giovanni) web interface.

    With the exponential growth of LHC (Large Hadron Collider) data in the years 2010-2012, distributed computing has become the established way to analyze collider data. The ATLAS experiment Grid infrastructure includes more than 130 sites worldwide, ranging from large national computing centres to smaller university clusters. So far the storage technologies and access protocols to the clusters that host this tremendous amount of data vary from site to site. HTTP/WebDAV offers the possibility to use a unified industry standard to access the storage. We present the deployment and testing of HTTP/WebDAV for local and remote data access in the ATLAS experiment for the new data management system Rucio and the PanDA workload management system. Deployment and large scale tests have been performed using the Grid testing system HammerCloud and the ROOT HTTP plugin Davix.

  4. Developing Access Control Model of Web OLAP over Trusted and Collaborative Data Warehouses

    Science.gov (United States)

    Fugkeaw, Somchart; Mitrpanont, Jarernsri L.; Manpanpanich, Piyawit; Juntapremjitt, Sekpon

    This paper proposes the design and development of Role- based Access Control (RBAC) model for the Single Sign-On (SSO) Web-OLAP query spanning over multiple data warehouses (DWs). The model is based on PKI Authentication and Privilege Management Infrastructure (PMI); it presents a binding model of RBAC authorization based on dimension privilege specified in attribute certificate (AC) and user identification. Particularly, the way of attribute mapping between DW user authentication and privilege of dimensional access is illustrated. In our approach, we apply the multi-agent system to automate flexible and effective management of user authentication, role delegation as well as system accountability. Finally, the paper culminates in the prototype system A-COLD (Access Control of web-OLAP over multiple DWs) that incorporates the OLAP features and authentication and authorization enforcement in the multi-user and multi-data warehouse environment.

  5. Integrating open-source technologies to build low-cost information systems for improved access to public health data

    Oberle Mark W

    2008-06-01

    Full Text Available Abstract Effective public health practice relies on the availability of public health data sources and assessment tools to convey information to investigators, practitioners, policy makers, and the general public. Emerging communication technologies on the Internet can deliver all components of the "who, what, when, and where" quartet more quickly than ever with a potentially higher level of quality and assurance, using new analysis and visualization tools. Open-source software provides the opportunity to build low-cost information systems allowing health departments with modest resources access to modern data analysis and visualization tools. In this paper, we integrate open-source technologies and public health data to create a web information system which is accessible to a wide audience through the Internet. Our web application, "EpiVue," was tested using two public health datasets from the Washington State Cancer Registry and Washington State Center for Health Statistics. A third dataset shows the extensibility and scalability of EpiVue in displaying gender-based longevity statistics over a twenty-year interval for 3,143 United States counties. In addition to providing an integrated visualization framework, EpiVue's highly interactive web environment empowers users by allowing them to upload their own geospatial public health data in either comma-separated text files or MS Excel™ spreadsheet files and visualize the geospatial datasets with Google Maps™.

    Universal design in context of digitalisation has become an integrated part of international conventions and national legislations. A goal is to make the Web accessible for people of different genders, ages, backgrounds, cultures and physical, sensory and cognitive abilities. Political demands for universally designed solutions have raised questions about how it is achieved in practice. Developers, designers and legislators have looked towards the Web Content Accessibility Guidelines (WCAG) for answers. WCAG 2.0 has become the de facto standard for universal design on the Web. Some of the guidelines are directed at the general population, while others are targeted at more specific user groups, such as the visually impaired or hearing impaired. Issues related to cognitive impairments such as dyslexia receive less attention, although dyslexia is prevalent in at least 5-10% of the population. Navigation and search are two common ways of using the Web. However, while navigation has received a fair amount of attention, search systems are not explicitly included, although search has become an important part of people's daily routines. This paper discusses WCAG in the context of dyslexia for the Web in general and search user interfaces specifically. Although certain guidelines address topics that affect dyslexia, WCAG does not seem to fully accommodate users with dyslexia.

    2010-06-01

    Full Text Available Abstract Web applications for biology and medicine often need to integrate data from Entrez services provided by the National Center for Biotechnology Information. However, direct access to Entrez from a web browser is not possible due to 'same-origin' security restrictions. The use of "Asynchronous JavaScript and XML" (AJAX to create rich, interactive web applications is now commonplace. The ability to access Entrez via AJAX would be advantageous in the creation of integrated biomedical web resources. We describe EntrezAJAX, which provides access to Entrez eUtils and is able to circumvent same-origin browser restrictions. EntrezAJAX is easily implemented by JavaScript developers and provides identical functionality as Entrez eUtils as well as enhanced functionality to ease development. We provide easy-to-understand developer examples written in JavaScript to illustrate potential uses of this service. For the purposes of speed, reliability and scalability, EntrezAJAX has been deployed on Google App Engine, a freely available cloud service.

    Here we describe a web-accessible digital brain atlas of the common marmoset (Callithrix jacchus) at http://marmoset-brain.org:2008. We prepared the histological sections of the marmoset brain using various staining techniques. For virtual microscopy, high-resolution digital images of sections were obtained with Aperio Scanscope. The digital images were then converted to Zoomify files (zoomable multiresolution image files). Thereby, we could provide the multiresolution images of the marmoset brains for fast interactive viewing on the web via the Internet. In addition, we describe an automated method to obtain drawings of Nissl-stained sections.

    Full Text Available This paper presents a solution for accessing web services in a light-secure way. Because the payload of the messages is not so sensitive, it is taken care only about protecting the user name and the password used for authentication and authorization into the web services system. The advantage of this solution compared to the common used SSL is avoiding the overhead related to the handshake and encryption, providing a faster response to the clients. The solution is intended for Windows machines and is developed using the latest stable Microsoft technologies.

    2011-10-01

    Introducing message prompts at the 'point-of-choice' (POC) between stairs and escalators increases stair choice in 'public-access' settings (e.g. malls). For nationwide campaigns, plentiful POCs appear needed. We audited the availability of POCs in public-access settings across England. Boundaries for 25 urban areas (population=6,829,874) were verified using Ordinance Survey maps, which showed all airports and train/tram stations. Malls and bus stations were identified from commercial listings and local authority web-pages. From September 2010-March 2011 two investigators visually inspected all venues (N=410), counting 'true' POCs and 'quasi' POCs (i.e. instances where stairs were visible from, but not adjacent to, escalators). 5% of venues had ≥1 true POC (quasi POC=3%). Aggregating across areas, there was a true and quasi POC for every 243,924 and 379,437 people, respectively. There were regional variations; one area had 10 true/quasi POCs, whilst 10/24 remaining areas had none. POCs were more common in airports (4/6 venues) than malls (11/85) and train stations (4/215). Although public-access POCs reach sizeable audiences, their availability in England is sporadic, precluding nationwide campaigns. Interventions should be considered locally, based on available POCs. Work/community venues (e.g. offices, hospitals), where pedestrians choose between stairs and elevators, may provide greater intervention opportunities. Copyright © 2011 Elsevier Inc.

    In 2008 a prototype, web-based system was launched which provided information for different user groups interested in European public health topics. The EUPHIX system contained scientifically sound data, with presentations as well as textual information. The information was structured according to the European Community Health Indicators (ECHI) shortlist. The information included different types of data presentations (tables, interactive graphs and maps), explanatory texts and overviews of the data sources and the literature used. The content was produced by a network of European experts according to a structured, peer-reviewed editorial process. Thus EUPHIX provided an easily accessible, comprehensive, state-of-the-art information source. To ensure that it will continue, financial support will be needed. Co-ownership by the European Commission and the Member States seems an appropriate solution.

  15. A web product data management system based on Simple Object Access Protocol

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    A new web product data management architecture is presented. The three-tier web architecture and Simple Object Access Protocol (SOAP) are combined to build the web-based product data management (PDM) system which includes three tiers: the user services tier, the business services tier, and the data services tier. The client service component uses the serverside technology, and Extensible Markup Language (XML) web service which uses SOAP as the communication protocol is chosen as the business service component. To illustrate how to build a web-based PDM system using the proposed architecture,a case PDM system which included three logical tires was built. To use the security and central management features of the database, a stored procedure was recommended in the data services tier. The business object was implemented as an XML web service so that client could use standard internet protocols to communicate with the business object from any platform. In order to satisfy users using all sorts of browser, the server-side technology and Microsoft ASP.NET was used to create the dynamic user interface.

    At present there is the tendency of uniting efforts of scientific establishments and libraries for using information - communication medium with the purpose of information support of research and pedagogical activity in Moldova. The efficient access to the scientific and technical literature and, first of all, to the new publications, is necessary practically for all scientists and experts irrespective of a field of knowledge, in which they work. Research institutions, knowing how to receive access to the electron information and to use it intellectually, realize that it effects positively the quality and outcomes of the research process. It is obvious, that to ensure maximum utilization of the new information stream by habitual methods is impossible. New non-traditional approaches are necessary for the increase of the level of information provision of scientists and experts. Creation of electron libraries, realizing qualitatively other level of production, storage, organization and distribution of various information is the most effective way to gin this object. The access to the electron versions of scientific journals allows to reduce the acuteness of shortage of scientific literature, the electron information becomes accessible before the publication of paper version of a journal, and taking into account the delivery time of foreign issues into Moldova, this outstripping can reach several months.

    2008-06-01

    With the progress of information technologies and astronomical observation technologies, as an example of cyber-infrastructure based sciences, the Virtual Observatory (VO) is initiated and spreaded quickly. More and more on-line accessible database systems and different kinds of services are available. Although astronomers have been aware of the importance of the interoperability, integrated access to the on-line information is still difficult. The SkyMouse is a smart system developed by Chinese Virtual Observatory project to let us access different online resource systems easier than ever. Not like some VO efforts on uniformed access systems, for example, NVO DataScope, SkyMouse tries to show a comprehensive overview for a specific object, but not to snatch as much data as possible. Stimulated by a simple "Mouse Over" on an interested object name, various VO-compliant and traditional databases, i.e. SIMBAD, NED, VizieR, DSS, ADS, are queried by the SkyMouse. An overview for the given object, including basic information, image, observation and references, is displayed in the user's default web browser. In this article, the authors will introduce the framework of SkyMouse. During the development of SkyMouse, various Web services will be called. In order to invoke these Web services, two problems must be solved, i.e. interoperability and performance. In the paper, a detailed description for these problems and the authors' resolution are given.

    hosted these Web Services as a part of the SCEC Community Modeling Environment (SCEC/CME) ITR Project (http://www.scec.org/cme). We have implemented Web Services for several of the reasons sited previously. For example, we implemented a FORTRAN-based Earthquake Rupture Forecast (ERF) as a Web Service for use by client computers that don't support a FORTRAN runtime environment. We implemented a Generic Mapping Tool (GMT) Web Service for use by systems that don't have local access to GMT. We implemented a Hazard Map Calculator Web Service to execute Hazard calculations that are too computationally intensive to run on a local system. We implemented a Coordinate Conversion Web Service to enforce a standard and consistent method for converting between UTM and Lat/Lon. Our experience developing these services indicates both strengths and weakness in current Web Service technology. Client programs that utilize Web Services typically need network access, a significant disadvantage at times. Programs with simple input and output parameters were the easiest to implement as Web Services, while programs with complex parameter-types required a significant amount of additional development. We also noted that Web services are very data-oriented, and adapting object-oriented software into the Web Service model proved problematic. Also, the Web Service approach of converting data types into XML format for network transmission has significant inefficiencies for some data sets.

  19. Public finance policy strategies to increase access to preconception care.

    Science.gov (United States)

    Johnson, Kay A

    2006-09-01

    Policy and finance barriers reduce access to preconception care and, reportedly, limit professional practice changes that would improve the availability of needed services. Millions of women of childbearing age (15-44) lack adequate health coverage (i.e., uninsured or underinsured), and others live in medically underserved areas. Service delivery fragmentation and lack of professional guidelines are additional barriers. This paper reviews barriers and opportunities for financing preconception care, based on a review and analysis of state and federal policies. We describe states' experiences with and opportunities to improve health coverage, through public programs such as Medicaid, Medicaid waivers, and the State Children's Health Insurance Program (SCHIP). The potential role of Title V and of community health centers in providing primary and preventive care to women also is discussed. In these and other public health and health coverage programs, opportunities exist to finance preconception care for low-income women. Three major policy directions are discussed. To increase access to preconception care among women of childbearing age, the federal and state governments have opportunities to: (1) improve health care coverage, (2) increase the supply of publicly subsidized health clinics, and (3) direct delivery of preconception screening and interventions in the context of public health programs.

    ChEMBL is now a well-established resource in the fields of drug discovery and medicinal chemistry research. The ChEMBL database curates and stores standardized bioactivity, molecule, target and drug data extracted from multiple sources, including the primary medicinal chemistry literature. Programmatic access to ChEMBL data has been improved by a recent update to the ChEMBL web services (version 2.0.x, https://www.ebi.ac.uk/chembl/api/data/docs), which exposes significantly more data from the underlying database and introduces new functionality. To complement the data-focused services, a utility service (version 1.0.x, https://www.ebi.ac.uk/chembl/api/utils/docs), which provides RESTful access to commonly used cheminformatics methods, has also been concurrently developed. The ChEMBL web services can be used together or independently to build applications and data processing workflows relevant to drug discovery and chemical biology.

  1. A Web Service for File-Level Access to Disk Images

    2014-07-01

    Full Text Available Digital forensics tools have many potential applications in the curation of digital materials in libraries, archives and museums (LAMs. Open source digital forensics tools can help LAM professionals to extract digital contents from born-digital media and make more informed preservation decisions. Many of these tools have ways to display the metadata of the digital media, but few provide file-level access without having to mount the device or use complex command-line utilities. This paper describes a project to develop software that supports access to the contents of digital media without having to mount or download the entire image. The work examines two approaches in creating this tool: First, a graphical user interface running on a local machine. Second, a web-based application running in web browser. The project incorporates existing open source forensics tools and libraries including The Sleuth Kit and libewf along with the Flask web application framework and custom Python scripts to generate web pages supporting disk image browsing.

    Recent advances in wireless broadband services and coverage have made access to the internet possible in remote locations. Users can now access the web via an ever increasing number of small, handheld devices specifically designed to allow voice and data exchange using this expanding service. So called PDA phones or smartphones blend the features of traditional PDA devices with telecommunications capabilities. The University of Wisconsin - Madison, Space Science and Engineering Center (SSEC) has produced a web site holding a variety of meteorological image and text displays optimized for this new technology. The site features animations of real-time radar and satellite clouds with value added graphical overlays of severe watches and warnings. Products focus on remotely sensed information supplemented with conventional ground observations. The PDA Animated Weather (PAW) website has rapidly been adopted by numerous institutions and individuals desiring access to real-time meteorological information independent of their location. Of particular note are users that can be classified as first responders, including foreign and domestic based police and file departments. This paper offers an overview of the PAW project including product design, automated production and web presentation. Numerous examples of user applications will be presented, planned future products and functionality will be discussed.

    Full Text Available Remote Sensing, an open access journal (http://www.mdpi.com/journal/remotesensing has grown at rapid pace since its first publication five years ago, and has acquired a strong reputation. It is a “pathfinder” being the first open access journal in remote sensing. For those academics who were used to waiting a year or two for their peer-reviewed scientific work to be reviewed, revised, edited, and published, Remote Sensing offers a publication time frame that is unheard of (in most cases, less than four months. However, we do this after multiple peer-reviews, multiple revisions, much editorial scrutiny and decision-making, and professional editing by an editorial office before a paper is published online in our tight time frame, bringing a paradigm shift in scientific publication. As a result, there has been a swift increase in submissions of higher and higher quality manuscripts from the best authors and institutes working on Remote Sensing, Geographic Information Systems (GIS, Global Navigation Satellite System (GNSS, GIScience, and all related geospatial science and technologies from around the world. The purpose of this editorial is to update everyone interested in Remote Sensing on the progress made over the last year, and provide an outline of our vision for the immediate future. [...

In this case report, we describe the development and use of Web 2.0 technologies including Yahoo! Pipes within a public health application that integrates animal, human, and temperature data to assess the risk of West Nile Virus (WNV) outbreaks. The results of development and testing suggest that while Web 2.0 applications are reasonable environments for rapid prototyping, they are not mature enough for large-scale public health data applications. The application, in fact a "systems of systems," often failed due to varied timeouts for application response across web sites and services, internal caching errors, and software added to web sites by administrators to manage the load on their servers. In spite of these concerns, the results of this study demonstrate the potential value of grid computing and Web 2.0 approaches in public health informatics.

  11. Increasing access to terrestrial ecology and remote sensing (MODIS) data through Web services and visualization tools

    Science.gov (United States)

    Santhana Vannan, S.; Cook, R. B.; Wei, Y.

    2012-12-01

    In recent years user access to data and information is increasingly handled through tools, services, and applications. Standards-based services have facilitated this development. These service-based methods to access data has boosted the use of data and in increasingly complex ways. The Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) has taken the approach of service-based access to data and visualization for distribution and visualization of its terrestrial ecology data, including MODIS (Moderate Resolution Imaging Spectroradiometer) remote sensing data products. The MODIS data products are highly useful for field research. The spectral, spatial and temporal characteristics of MODIS products have made them an important data source for analyzing key science questions relating to Earth system processes at multiple spatial and temporal scales. However, MODIS data volume and the complexity in data format make it less usable in some cases. To solve this usability issue, the ORNL DAAC has developed a system that prepares and distributes subsets of selected MODIS land products in a scale and format useful for field researchers. Web and Web service tools provide MODIS subsets in comma-delimited text format and in GIS compatible GeoTIFF format. Users can download and visualize MODIS subsets for a set of pre-defined locations, order MODIS subsets for any land location or automate the process of subset extraction using a SOAP-based Web service. The MODIS tools and services can be extended to support the large volume of data that would be produced by the various decadal survey missions. http://daac.ornl.gov/MODIS . The ORNL DAAC has also created a Web-based Spatial Data Access Tool (SDAT) that enables users to browse, visualize, and download a wide variety of geospatial data in various user-selected spatial/temporal extents, formats, and projections. SDAT is based on Open Geospatial Consortium (OGC) Web service standards that allows users to

    2012-12-01

    Using the STOQS Web Application for Access to in situ Oceanographic Data Mike McCann 7 August 2012 With increasing measurement and sampling capabilities of autonomous oceanographic platforms (e.g. Gliders, Autonomous Underwater Vehicles, Wavegliders), the need to efficiently access and visualize the data they collect is growing. The Monterey Bay Aquarium Research Institute has designed and built the Spatial Temporal Oceanographic Query System (STOQS) specifically to address this issue. The need for STOQS arises from inefficiencies discovered from using CF-NetCDF point observation conventions for these data. The problem is that access efficiency decreases with decreasing dimension of CF-NetCDF data. For example, the Trajectory Common Data Model feature type has only one coordinate dimension, usually Time - positions of the trajectory (Depth, Latitude, Longitude) are stored as non-indexed record variables within the NetCDF file. If client software needs to access data between two depth values or from a bounded geographic area, then the whole data set must be read and the selection made within the client software. This is very inefficient. What is needed is a way to easily select data of interest from an archive given any number of spatial, temporal, or other constraints. Geospatial relational database technology provides this capability. The full STOQS application consists of a Postgres/PostGIS database, Mapserver, and Python-Django running on a server and Web 2.0 technology (jQuery, OpenLayers, Twitter Bootstrap) running in a modern web browser. The web application provides faceted search capabilities allowing a user to quickly drill into the data of interest. Data selection can be constrained by spatial, temporal, and depth selections as well as by parameter value and platform name. The web application layer also provides a REST (Representational State Transfer) Application Programming Interface allowing tools such as the Matlab stoqstoolbox to retrieve data

    Full Text Available We investigate the licensed shared access (LSA concept based spectrum sharing ideas between public safety (PS and commercial radio systems. While the concept of LSA has been well developed, it has not been thoroughly investigated from the public safety (PS users’ point of view, who have special requirements and also should benefit from the concept. Herein, we discuss the alternatives for spectrum sharing between PS and commercial systems. In particular, we proceed to develop robust solutions for LSA use cases where connections to the LSA system may fail. We simulate the proposed system with different failure models. The results show that the method offers reliable LSA spectrum sharing in various conditions assuming that the system parameters are set properly. The paper gives guidelines to set these parameters.

    2015-03-13

    According to the World Health Organization, one in every 10 people has a disability, and more than two-thirds of them do not receive any type of oral dental care. The Brazilian Constitution of 1988 guarantees all civilians including disabled people the right to healthcare, shaping the guidelines of the Brazilian National Health Care System (Sistema Único de Saúde--SUS). However, there is limited information about the true accessibility of dental services. This study evaluated the accessibility of public dental services to persons with disabilities in Fortaleza, Ceará, which has the third highest disability rate in Brazil. A cross-sectional quantitative study using structured questionnaires was administered to dentists (n = 89) and people with disabilities (n = 204) to evaluate the geographical, architectural, and organizational accessibility of health facilities, the communication between professionals and patients with disabilities, the demand for dental services, and factors influencing the use of dental services by people with motor, visual, and hearing impairments. 43.1% of people with disabilities do not recognize their service as a priority of Basic Health Units (BHU), 52.5% do not usually seek dental care, and of those who do (n = 97), 76.3% find it difficult to receive care and 84.5% only seek care on an emergency basis. Forty-five percent are unaware of the services offered in the BHU. Of the dentists, 56.2% reported difficulty in communicating with deaf patients, and 97.8% desired interpreters stationed in the BHU. People with disabilities gave better accessibility ratings than dentists (p = 0.001). 37.3% of the patients and 43.8% of dentists reported inadequate physical access infrastructure (including doors, hallways, waiting rooms, and offices). Dentists (60%) reported unsafe environments and transportation difficulties as geographical barriers, while most people with disabilities did not report noticing these barriers. While access to dental

    2015-04-01

    The sharing of research data is a new challenge for the scientific community that may benefit from a large amount of information to solve environmental issues and sustainability in agriculture and urban contexts. Prerequisites for this challenge is the development of an infrastructure that ensure access, management and preservation of data, technical support for a coordinated and harmonious management of data that, in the framework of Open Data Policies, should encourages the reuse and the collaboration. The neogeography and the citizen as sensors approach, highlight that new data sources need a new set of tools and practices so to collect, validate, categorize, and use / access these "crowdsourced" data, that integrate the data sets produced in the scientific field, thus "feeding" the overall available data for analysis and research. When the scientific community embraces the dimension of collaboration and sharing, access and re-use, in order to accept the open innovation approach, it should redesign and reshape the processes of data management: the challenges of technological and cultural innovation, enabled by web 2.0 technologies, bring to the scenario where the sharing of structured and interoperable data will constitute the unavoidable building block to set up a new paradigm of scientific research. In this perspective the Institute of Biometeorology, CNR, whose aim is contributing to sharing and development of research data, has developed the "SensorWebHub" (SWH) infrastructure to support the scientific activities carried out in several research projects at national and international level. It is designed to manage both mobile and fixed open source meteorological and environmental sensors, in order to integrate the existing agro-meteorological and urban monitoring networks. The proposed architecture uses open source tools to ensure sustainability in the development and deployment of web applications with geographic features and custom analysis, as requested

    2016-02-01

    With the advances in high bandwidth communications and the proliferation of social media tools, education & outreach activities have become commonplace on ocean-bound research cruises. In parallel, advances in underwater robotics & other data collecting platforms, have made it possible to collect copious amounts of oceanographic data. This data then typically undergoes laborious, manual processing to transform it into quantitative information, which normally occurs post cruise resulting in significant lags between collecting data and using it for scientific discovery. This presentation discusses how appropriately designed software systems, can be used to fulfill multiple objectives and attempt to leverage public engagement in order to compliment science goals. We will present two software platforms: the first is a web browser based tool that was developed for real-time tracking of multiple underwater robots and ships. It was designed to allow anyone on board to view or control it on any device with a web browser. It opens up the possibility of remote teleoperation & engagement and was easily adapted to enable live streaming over the internet for public outreach. While the tracking system provided context and engaged people in real-time, it also directed interested participants to Squidle, another online system. Developed for scientists, Squidle supports data management, exploration & analysis and enables direct access to survey data reducing the lag in data processing. It provides a user-friendly streamlined interface that integrates advanced data management & online annotation tools. This system was adapted to provide a simplified user interface, tutorial instructions and a gamified ranking system to encourage "citizen science" participation. These examples show that through a flexible design approach, it is possible to leverage the development effort of creating science tools to facilitate outreach goals, opening up the possibility for acquiring large volumes of

    A Large Ion Collider Experiment (ALICE) is the heavy-ion detector designed to study the physics of strongly interacting matter and the quark-gluon plasma at the CERN Large Hadron Collider (LHC). The online Data Quality Monitoring (DQM) plays an essential role in the experiment operation by providing shifters with immediate feedback on the data being recorded in order to quickly identify and overcome problems. An immediate access to the DQM results is needed not only by shifters in the control room but also by detector experts worldwide. As a consequence, a new web application has been developed to dynamically display and manipulate the ROOT-based objects produced by the DQM system in a flexible and user friendly interface. The architecture and design of the tool, its main features and the technologies that were used, both on the server and the client side, are described. In particular, we detail how we took advantage of the most recent ROOT JavaScript I/O and web server library to give interactive access to ROOT objects stored in a database. We describe as well the use of modern web techniques and packages such as AJAX, DHTMLX and jQuery, which has been instrumental in the successful implementation of a reactive and efficient application. We finally present the resulting application and how code quality was ensured. We conclude with a roadmap for future technical and functional developments.

  1. Do you web 2.0? public libraries and social networking

    2011-01-01

    Web 2.0 technology is a hot topic at the moment, and public librarians in particular are beginning to feel the pressure to apply these tools. Indeed, Web 2.0 has the potential to transform library services, but only if the policy and strategy for those services are ready to be transformed. The author not only reviews these tools and provides practical advice and case studies on how they can be applied in the public library setting, but also recommends the policies and business cases that begin to create a new strategy for public libraries.particularly geared to the public library settingadvice

    Full Text Available Problem statement: To find frequently occurring Sequential patterns from web log file on the basis of minimum support provided. We introduced an efficient strategy for discovering Web usage mining is the application of sequential pattern mining techniques to discover usage patterns from Web data, in order to understand and better serve the needs of Web-based applications. Approach: The approaches adopt a divide-and conquer pattern-growth principle. Our proposed method combined tree projection and prefix growth features from pattern-growth category with position coded feature from early-pruning category, all of these features are key characteristics of their respective categories, so we consider our proposed method as a pattern growth, early-pruning hybrid algorithm. Results: Our proposed Hybrid algorithm eliminated the need to store numerous intermediate WAP trees during mining. Since only the original tree was stored, it drastically cuts off huge memory access costs, which may include disk I/O cost in a virtual memory environment, especially when mining very long sequences with millions of records. Conclusion: An attempt had been made to our approach for improving efficiency. Our proposed method totally eliminates reconstructions of intermediate WAP-trees during mining and considerably reduces execution time.

    A method for providing uniform transparent access to disparate distributed information systems was demonstrated. A prototype testing interface was developed to access documentation and information using publicly available hypermedia tools. The prototype gives testers a uniform, platform-independent user interface to on-line documentation, user manuals, and mission-specific test and operations data. Mosaic was the common user interface, and HTML (Hypertext Markup Language) provided hypertext capability.

    Computational tools that predict the effects of daily sleep/wake amounts on neurobehavioral performance are critical components of fatigue management systems, allowing for the identification of periods during which individuals are at increased risk for performance errors. However, none of the existing computational tools is publicly available, and the commercially available tools do not account for the beneficial effects of caffeine on performance, limiting their practical utility. Here, we introduce 2B-Alert Web, an open-access tool for predicting neurobehavioral performance, which accounts for the effects of sleep/wake schedules, time of day, and caffeine consumption, while incorporating the latest scientific findings in sleep restriction, sleep extension, and recovery sleep. We combined our validated Unified Model of Performance and our validated caffeine model to form a single, integrated modeling framework instantiated as a Web-enabled tool. 2B-Alert Web allows users to input daily sleep/wake schedules and caffeine consumption (dosage and time) to obtain group-average predictions of neurobehavioral performance based on psychomotor vigilance tasks. 2B-Alert Web is accessible at: https://2b-alert-web.bhsai.org. The 2B-Alert Web tool allows users to obtain predictions for mean response time, mean reciprocal response time, and number of lapses. The graphing tool allows for simultaneous display of up to seven different sleep/wake and caffeine schedules. The schedules and corresponding predicted outputs can be saved as a Microsoft Excel file; the corresponding plots can be saved as an image file. The schedules and predictions are erased when the user logs off, thereby maintaining privacy and confidentiality. The publicly accessible 2B-Alert Web tool is available for operators, schedulers, and neurobehavioral scientists as well as the general public to determine the impact of any given sleep/wake schedule, caffeine consumption, and time of day on performance of a

    For most people, traveling through urban and built environments is straightforward. However, for people with physical disabilities, even a short trip can be difficult and perhaps impossible. This paper provides the design and implementation of a web-based system for the routing and prescriptive analysis of pedestrians with different physical abilities within built environments. U-Access, as a routing tool, provides pedestrians with the shortest feasible route with respect to one of three differing ability levels, namely, peripatetic (unaided mobility), aided mobility (mobility with the help of a cane, walker or crutches) and wheelchair users. U-Access is also an analytical tool that can help identify obstacles in built environments that create routing discrepancies among pedestrians with different physical abilities. This paper discusses the system design, including database, algorithm and interface specifications, and technologies for efficiently delivering results through the World Wide Web (WWW). This paper also provides an illustrative example of a routing problem and an analytical evaluation of the existing infrastructure which identifies the obstacles that pose the greatest discrepancies between physical ability levels. U-Access was evaluated by wheelchair users and route experts from the Center for Disability Services at The University of Utah, USA.

    The 'concerned significant others' (CSOs) of people with problem gambling frequently seek professional support. However, there is surprisingly little research investigating the characteristics or help-seeking behaviour of these CSOs, particularly for web-based counselling. The aims of this study were to describe the characteristics of CSOs accessing the web-based counselling service (real time chat) offered by the Australian national gambling web-based counselling site, explore the most commonly reported CSO impacts using a new brief scale (the Problem Gambling Significant Other Impact Scale: PG-SOIS), and identify the factors associated with different types of CSO impact. The sample comprised all 366 CSOs accessing the service over a 21 month period. The findings revealed that the CSOs were most often the intimate partners of problem gamblers and that they were most often females aged under 30 years. All CSOs displayed a similar profile of impact, with emotional distress (97.5%) and impacts on the relationship (95.9%) reported to be the most commonly endorsed impacts, followed by impacts on social life (92.1%) and finances (91.3%). Impacts on employment (83.6%) and physical health (77.3%) were the least commonly endorsed. There were few significant differences in impacts between family members (children, partners, parents, and siblings), but friends consistently reported the lowest impact scores. Only prior counselling experience and Asian cultural background were consistently associated with higher CSO impacts. The findings can serve to inform the development of web-based interventions specifically designed for the CSOs of problem gamblers.

    Over the past decade, the increasing availability of the World Wide Web has held out the possibility that the efficiency of scientific measurements could be enhanced in cases where experiments were being conducted at distant facilities. Examples of early successes have included X-ray diffraction (XRD) experimental measurements of protein crystal structures at synchrotrons and access to scanning electron microscopy (SEM) and NMR facilities by users from institutions that do not possess such advanced capabilities. Experimental control, visual contact, and receipt of results has used some form of X forwarding and/or VNC (virtual network computing) software that transfers the screen image of a server at the experimental site to that of the users' home site. A more recent development is a web services platform called Science Studio that provides teams of scientists with secure links to experiments at one or more advanced research facilities. The software provides a widely distributed team with a set of controls and screens to operate, observe, and record essential parts of the experiment. As well, Science Studio provides high speed network access to computing resources to process the large data sets that are often involved in complex experiments. The simple web browser and the rapid transfer of experimental data to a processing site allow efficient use of the facility and assist decision making during the acquisition of the experimental results. The software provides users with a comprehensive overview and record of all parts of the experimental process. A prototype network is described involving X-ray beamlines at two different synchrotrons and an SEM facility. An online parallel processing facility has been developed that analyzes the data in near-real time using stream processing. Science Studio and can be expanded to include many other analytical applications, providing teams of users with rapid access to processed results along with the means for detailed

  8. Web 2.0 Sites for Collaborative Self-Access: The Learning Advisor vs. Google®

    2011-09-01

    Full Text Available While Web 2.0 technologies provide motivated, self-access learners with unprecedented opportunities for language learning, Web 2.0 designs are not of universally equal value for learning. This article reports on research carried out at Indiana University Bloomington using an empirical method to select websites for self-access language learning. Two questions related to Web 2.0 recommendations were asked: (1 How do recommended Web 2.0 sites rank in terms of interactivity features? (2 How likely is a learner to find highly interactive sites on their own? A list of 20 sites used for supplemental and self-access activities in language programs at five universities was compiled and provided the initial data set. Purposive sampling criteria revealed 10 sites truly represented Web 2.0 design. To address the first question, a feature analysis was applied (Herring, The international handbook of internet research. Berlin: Springer, 2008. An interactivity framework was developed from previous research to identify Web 2.0 design features, and sites were ranked according to feature quantity. The method used to address the second question was an interconnectivity analysis that measured direct and indirect interconnectivity within Google results. Highly interactive Web 2.0 sites were not prominent in Google search results, nor were they often linked via third party sites. It was determined that, using typical keywords or searching via blogs and recommendation sites, self-access learners were highly unlikely to find the most promising Web 2.0 sites for language learning. A discussion of the role of the learning advisor in guiding Web 2.0 collaborative self-access, as well as some strategic short cuts to quick analysis, conclude the article.

    Although Web-based treatments have significant potential to assess and treat difficult-to-reach populations, such as trauma-exposed adolescents, the extent that such treatments are accessed and used is unclear. The present study evaluated the proportion of adolescents who accessed and completed a Web-based treatment for postdisaster mental health symptoms. Correlates of access and completion were examined. A sample of 2,000 adolescents living in tornado-affected communities was assessed via structured telephone interview and invited to a Web-based treatment. The modular treatment addressed symptoms of posttraumatic stress disorder, depression, and alcohol and tobacco use. Participants were randomized to experimental or control conditions after accessing the site. Overall access for the intervention was 35.8%. Module completion for those who accessed ranged from 52.8% to 85.6%. Adolescents with parents who used the Internet to obtain health-related information were more likely to access the treatment. Adolescent males were less likely to access the treatment. Future work is needed to identify strategies to further increase the reach of Web-based treatments to provide clinical services in a postdisaster context. (c) 2015 APA, all rights reserved).

    In late 2012, the National Renewable Energy Laboratory (NREL) initiated the Solar Access to Public Capital (SAPC) working group. Backed by a three-year funding facility from the U.S. Department of Energy (DOE), NREL set out to organize the solar, legal, banking, capital markets, engineering, and other relevant stakeholder communities in order to open lower-cost debt investment for solar asset deployment. SAPC engaged its members to standardize contracts, develop best practices, and comprehend how the rating agencies perceive solar project portfolios as an investment asset class. Rating agencies opine on the future creditworthiness of debt obligations. Issuers often seek investment-grade ratings from the rating agencies in order to satisfy the desires of their investors. Therefore, for the solar industry to access larger pools of capital at a favorable cost, it is critical to increase market participants' understanding of solar risk parameters. The process provided valuable information to address rating agency perceptions of risk that, without such information, could require costly credit enhancement or higher yields to attract institutional investors. Two different securities were developed--one for a hypothetical residential solar portfolio and one for a hypothetical commercial solar portfolio. Five rating agencies (Standard and Poor's, Moody's, KBRA, Fitch, and DBRS) participated and provided extensive feedback, some through conversations that extended several months. The findings represented in this report are a composite summary of that feedback and do not indicate any specific feedback from any single rating agency.

    2008-01-01

    Electronic Health Record (EHR) systems are becoming more and more sophisticated and include nowadays numerous applications, which are not only accessed by medical professionals, but also by accounting and administrative personnel. This could represent a problem concerning basic rights such as privacy and confidentiality. The principles, guidelines and recommendations compiled by the OECD protection of privacy and trans-border flow of personal data are described and considered within health information system development. Granting access to an EHR should be dependent upon the owner of the record; the patient: he must be entitled to define who is allowed to access his EHRs, besides the access control scheme each health organization may have implemented. In this way, it's not only up to health professionals to decide who have access to what, but the patient himself. Implementing such a policy is walking towards patient empowerment which society should encourage and governments should promote. The paper then introduces a technical solution based on web security standards. This would give patients the ability to monitor and control which entities have access to their personal EHRs, thus empowering them with the knowledge of how much of his medical history is known and by whom. It is necessary to create standard data access protocols, mechanisms and policies to protect the privacy rights and furthermore, to enable patients, to automatically track the movement (flow) of their personal data and information in the context of health information systems. This solution must be functional and, above all, user-friendly and the interface should take in consideration some heuristics of usability in order to provide the user with the best tools. The current official standards on confidentiality and privacy in health care, currently being developed within the EU, are explained, in order to achieve a consensual idea of the guidelines that all member states should follow to transfer

    NOAA's National Centers for Environmental Information (NCEI) ensures the security and widespread availability of marine geophysical data through long-term stewardship. NCEI stewards bathymetric data and products from numerous sources, including near-shore hydrographic survey data from NOAA's National Ocean Service, deep-water multibeam and single-beam echosounder data collected by U.S. and non-U.S. institutions, as well as digital elevation models (DEMs) that integrate ocean bathymetry and land topography. These data can be discovered, visualized, and accessed via a suite of ArcGIS web services and by using a web map which integrates these component services: the Bathymetric Data Viewer. The services provide data coverage (e.g. survey tracklines, DEM footprints), color shaded relief visualizations of bathymetry, and seamless mosaics of elevation data. These services are usable in web applications (both within and outside NOAA), and in desktop GIS software. Users can utilize the Bathymetric Data Viewer to narrow down data of interest, identify datasets, then submit an order to NCEI's extract system for data retrieval.

    Full Text Available Abstract Background Application of virtual slides (VS, the digitalization of complete glass slides, is in its infancy to be implemented in routine diagnostic surgical pathology and to issues that are related to tissue-based diagnosis, such as education and scientific publication. Approach Electronic publication in Pathology offers new features of scientific communication in pathology that cannot be obtained by conventional paper based journals. Most of these features are based upon completely open or partly directed interaction between the reader and the system that distributes the article. One of these interactions can be applied to microscopic images allowing the reader to navigate and magnify the presented images. VS and interactive Virtual Microscopy (VM are a tool to increase the scientific value of microscopic images. Technology and Performance The open access journal Diagnostic Pathology http://www.diagnosticpathology.org has existed for about five years. It is a peer reviewed journal that publishes all types of scientific contributions, including original scientific work, case reports and review articles. In addition to digitized still images the authors of appropriate articles are requested to submit the underlying glass slides to an institution (DiagnomX.eu, and Leica.com for digitalization and documentation. The images are stored in a separate image data bank which is adequately linked to the article. The normal review process is not involved. Both processes (peer review and VS acquisition are performed contemporaneously in order to minimize a potential publication delay. VS are not provided with a DOI index (digital object identifier.

    FLOSYS is an interactive web-accessible bioinformatics workflow system designed to assist biologists in multi-step data analyses. FLOSYS allows the user to create complex analysis pathways (protocols) graphically, similar to drawing a flowchart: icons representing particular bioinformatics tools are dragged and dropped onto a canvas and lines connecting those icons are drawn to specify the relationships between the tools. In addition, FLOSYS permits to select input-data, execute the protocol and store the results in a personal workspace. The three-tier architecture of FLOSYS has been implemented in Java and uses a relational database system together with new technologies for distributed and web computing such as CORBA, RMI, JSP and JDBC. The prototype of FLOSYS, which is part of the bioinformatics workbench AnaBench, is accessible on-line at http://malawimonas.bcm.umontreal.ca: 8091/anabench. The entire package is available on request to academic groups who wish to have a customized local analysis environment for research or teaching.

  1. A Dynamic Web Page Prediction Model Based on Access Patterns to Offer Better User Latency

    CERN Document Server

    Mukhopadhyay, Debajyoti; Saha, Dwaipayan; Kim, Young-Chon

    2011-01-01

    The growth of the World Wide Web has emphasized the need for improvement in user latency. One of the techniques that are used for improving user latency is Caching and another is Web Prefetching. Approaches that bank solely on caching offer limited performance improvement because it is difficult for caching to handle the large number of increasingly diverse files. Studies have been conducted on prefetching models based on decision trees, Markov chains, and path analysis. However, the increased uses of dynamic pages, frequent changes in site structure and user access patterns have limited the efficacy of these static techniques. In this paper, we have proposed a methodology to cluster related pages into different categories based on the access patterns. Additionally we use page ranking to build up our prediction model at the initial stages when users haven't already started sending requests. This way we have tried to overcome the problems of maintaining huge databases which is needed in case of log based techn...

    One of the biggest obstacles for the average Earth science student today is locating and obtaining satellite- based remote sensing datasets in a format that is accessible and optimal for their data analysis needs. At the Goddard Earth Sciences Data and Information Services Center (GES-DISC) alone, on the order of hundreds of Terabytes of data are available for distribution to scientists, students and the general public. The single biggest and time-consuming hurdle for most students when they begin their study of the various datasets is how to slog through this mountain of data to arrive at a properly sub-setted and manageable dataset to answer their science question(s). The GES DISC provides a number of tools for data access and visualization, including the Google-like Mirador search engine and the powerful GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure (Giovanni) web interface. Giovanni provides a simple way to visualize, analyze and access vast amounts of satellite-based Earth science data. Giovanni's features and practical examples of its use will be demonstrated, with an emphasis on how satellite remote sensing can help students understand recent events in the atmosphere and biosphere. Giovanni is actually a series of sixteen similar web-based data interfaces, each of which covers a single satellite dataset (such as TRMM, TOMS, OMI, AIRS, MLS, HALOE, etc.) or a group of related datasets (such as MODIS and MISR for aerosols, SeaWIFS and MODIS for ocean color, and the suite of A-Train observations co-located along the CloudSat orbital path). Recently, ground-based datasets have been included in Giovanni, including the Northern Eurasian Earth Science Partnership Initiative (NEESPI), and EPA fine particulate matter (PM2.5) for air quality. Model data such as the Goddard GOCART model and MERRA meteorological reanalyses (in process) are being increasingly incorporated into Giovanni to facilitate model- data intercomparison.

    2008-10-01

    Full Text Available Abstract Background In the last five years large online resources of human variability have appeared, notably HapMap, Perlegen and the CEPH foundation. These databases of genotypes with population information act as catalogues of human diversity, and are widely used as reference sources for population genetics studies. Although many useful conclusions may be extracted by querying databases individually, the lack of flexibility for combining data from within and between each database does not allow the calculation of key population variability statistics. Results We have developed a novel tool for accessing and combining large-scale genomic databases of single nucleotide polymorphisms (SNPs in widespread use in human population genetics: SPSmart (SNPs for Population Studies. A fast pipeline creates and maintains a data mart from the most commonly accessed databases of genotypes containing population information: data is mined, summarized into the standard statistical reference indices, and stored into a relational database that currently handles as many as 4 × 109 genotypes and that can be easily extended to new database initiatives. We have also built a web interface to the data mart that allows the browsing of underlying data indexed by population and the combining of populations, allowing intuitive and straightforward comparison of population groups. All the information served is optimized for web display, and most of the computations are already pre-processed in the data mart to speed up the data browsing and any computational treatment requested. Conclusion In practice, SPSmart allows populations to be combined into user-defined groups, while multiple databases can be accessed and compared in a few simple steps from a single query. It performs the queries rapidly and gives straightforward graphical summaries of SNP population variability through visual inspection of allele frequencies outlined in standard pie-chart format.

    The National Geophysical Data Center (NGDC) catalogs information on tsunamis, significant earthquakes, and volcanoes including effects such as fatalities and damage. NGDC also maintains a large collection of geologic hazards photos. All of these databases are now stored in an Oracle relational database management system (RDMS) and accessible over the Web as tables, reports and interactive maps. Storing the data in a RDMS facilitates the search for earthquake, tsunami and volcano data related to a specific event. For example, a user might be interested in all of the earthquakes greater than magnitude 8.0 that have occurred in Alaska. If the earthquake triggered a tsunami, the user could then directly access related information from the tsunami tables without having to run a separate search of the tsunami database. Users could also first access the tsunami database and then obtain related significant earthquake and volcano data. The ArcIMS-based interactive maps provide integrated Web-based GIS access to these hazards databases as well as additional auxiliary geospatial data. The first interactive map provides access to individual GIS layers of significant earthquakes, tsunami sources, tsunami effects, volcano locations, and various spatial reference layers including topography, population density, and political boundaries. The map service also provides ftp links and hyperlinks to additional hazards information such as NGDC's extensive collection of geologic hazards photos. For example, a user could display all of the significant earthquakes that have occurred in California and then by using a hyperlinks tool, display images showing damage from a specific earthquake such as the 1989 Loma Prieta event. The second interactive map allows users to display related natural hazards GIS layers. For example, a user might first display tsunami source locations and select tsunami effects as the related feature. Using a tool developed at NGDC, the user can then select a specific

    Reproducibility and reusability of research results is an important concern in scientific communication and science policy. A foundational element of reproducibility and reusability is the open and persistently available presentation of research data. However, many common approaches for primary data publication in use today do not achieve sufficient long-term robustness, openness, accessibility or uniformity. Nor do they permit comprehensive exploitation by modern Web technologies. This has led to several authoritative studies recommending uniform direct citation of data archived in persistent repositories. Data are to be considered as first-class scholarly objects, and treated similarly in many ways to cited and archived scientific and scholarly literature. Here we briefly review the most current and widely agreed set of principle-based recommendations for scholarly data citation, the Joint Declaration of Data Citation Principles (JDDCP). We then present a framework for operationalizing the JDDCP; and a set of initial recommendations on identifier schemes, identifier resolution behavior, required metadata elements, and best practices for realizing programmatic machine actionability of cited data. The main target audience for the common implementation guidelines in this article consists of publishers, scholarly organizations, and persistent data repositories, including technical staff members in these organizations.

    Inaccessible samples are an obstacle to the reproducibility of research and may cause waste of time and resources through duplication of sample collection and management. Within the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Mineral Resources there are various research communities who collect or generate physical samples as part of their field studies and analytical processes. Materials can be varied and could be rock, soil, plant materials, water, and even synthetic materials. Given the wide range of applications in CSIRO, each researcher or project may follow their own method of collecting, curating and documenting samples. In many cases samples and their documentation are often only available to the sample collector. For example, the Australian Resources Research Centre stores rock samples and research collections dating as far back as the 1970s. Collecting these samples again would be prohibitively expensive and in some cases impossible because the site has been mined out. These samples would not be easily discoverable by others without an online sample catalog. We identify some of the organizational and technical challenges to provide unambiguous and systematic access to geoscience samples, and present their solutions (e.g., workflow, persistent identifier and tools). We present the workflow starting from field sampling to sample publication on the Web, and describe how the International Geo Sample Number (IGSN) can be applied to identify samples along the process. In our test case geoscientific samples are collected as part of the Capricorn Distal Footprints project, a collaboration project between the CSIRO, the Geological Survey of Western Australia, academic institutions and industry partners. We conclude by summarizing the values of our solutions in terms of sample management and publication.

  13. Ethical policies on animal experiments are not compromised by whether a journal is freely accessible or charges for publication.

    Rands, S A

    2009-11-01

    The advent of the open access (OA) movement in publishing has been instrumental in causing a shift in the accessibility of research findings published in academic journals. The adoption of OA and other online publication models means that the results of scientific research published in journals using a free access (FA) framework are now available, free of charge, to anyone with access to the Internet. FA journals typically require a payment from the authors of a manuscript, which has raised concerns about the quality of work published in them; accepting payment from an author may compromise a journal's acceptance criteria. This study addresses whether journal policy on the treatment of animals is influenced by whether a journal follows a FA publishing model, and whether a requirement to pay for publication has an influence. A random sample of 332 biomedical journals listed in the ISI Web of Knowledge and Directory of Open Access Journals databases were assessed for whether they had an ethical policy on publishing animal studies, and what form of publication framework they used (103 of the journals followed a FA framework; 101 charged in some way for publication). Only 135 (40.7%) of the journals surveyed demanded that submissions comply with a pre-defined ethical stance. FA journals are just as likely to have an ethical policy on the treatment and presentation of animal studies as 'traditional', non-FA journals (significance of there being a difference: P = 0.98), and there is no relationship between policy and whether an author is required to pay for publication (significance of there being a difference: P = 0.57). Older journals are more likely to have an ethical policy (P = 0.03). There is, therefore, no obvious compromise shown by FA journals in the explicit policies on reporting studies involving animals. However, since anyone can read published FA studies online, FA journals that do not have an explicit policy about publishing animal research are urged to

    The progress in computer-aided drug design (CADD) approaches over the past decades accelerated the early-stage pharmaceutical research. Many powerful standalone tools for CADD have been developed in academia. As programs are developed by various research groups, a consistent user-friendly online graphical working environment, combining computational techniques such as pharmacophore mapping, similarity calculation, scoring, and target identification is needed. We presented a versatile, user-friendly, and efficient online tool for computer-aided drug design based on pharmacophore and 3D molecular similarity searching. The web interface enables binding sites detection, virtual screening hits identification, and drug targets prediction in an interactive manner through a seamless interface to all adapted packages (e.g., Cavity, PocketV.2, PharmMapper, SHAFTS). Several commercially available compound databases for hit identification and a well-annotated pharmacophore database for drug targets prediction were integrated in iDrug as well. The web interface provides tools for real-time molecular building/editing, converting, displaying, and analyzing. All the customized configurations of the functional modules can be accessed through featured session files provided, which can be saved to the local disk and uploaded to resume or update the history work. iDrug is easy to use, and provides a novel, fast and reliable tool for conducting drug design experiments. By using iDrug, various molecular design processing tasks can be submitted and visualized simply in one browser without installing locally any standalone modeling softwares. iDrug is accessible free of charge at http://lilab.ecust.edu.cn/idrug.

Heavy burden of life in urban makes health, especially reproductive health, never become first priority for urban poor community. This study is aimed to analyzed equity of urban poor community when accessing the reproductive health care. Methods:This is descriptive study with cross sectional design applied. There were 78 women residents of Penjaringansari II Flats in Surabaya selected by simple random sampling (α=10% as respondents. Penjaringansari II Flats was choosen because it is a slum area that residence by unskilled labours and odd employees. The need fulfillment of respondents in reproductive health care was analyzed by spider web analysis. result: Most of respondents (55.1% were first married before 20 years old. There were 60.5% of them gave birth before 20 years old also, so it belongs to high risk pregnant women. Spider web area for health care of under age married was less than ideal age married which means that under age married urban poor experienced inequity for ANC health services. Approximately 10.3% of respondents had never use contraceptives because they fear of side effects and inhibiton of their husband. conclutions:Better equity shown in the prevention of cervical cancer. Being perceived as the poor who need assistance, free pap smear was often held by Penjaringansari II residents. Poor conditions experienced by a group not only can promote health care inequity, but also promote health care equity. recomendation:Health care equity for urban poor can be pursued through both aid schemes provided by the community or the government.

    This paper deals with a virtual anastylosis of a Greek Archaic statue from ancient Sicily and the development of a public outreach protocol for those with visual impairment or cognitive disabilities through the application of three-dimensional (3-D) printing and haptic technology. The case study consists of the marble head from Leontinoi in southeastern Sicily, acquired in the 18th century and later kept in the collection of the Museum of Castello Ursino in Catania, and a marble torso, retrieved in 1904 and since then displayed in the Archaeological Museum of Siracusa. Due to similar stylistic features, the two pieces can be dated to the end of the sixth century BC. Their association has been an open problem, largely debated by scholars, who have based their hypotheses on comparisons between pictures, but the reassembly of the two artifacts was never attempted. As a result the importance of such an artifact, which could be the only intact Archaic statue of a kouros ever found in Greek Sicily, has not fully been grasped by the public. Consequently, the curatorial dissemination of the knowledge related with such artifacts is purely based on photographic material. As a response to this scenario, the two objects have been 3-D scanned and virtually reassembled. The result has been shared digitally with the public via a web platform and, in order to include increased accessibility for the public with physical or cognitive disabilities, copies of the reassembled statue have been 3-D printed and an interactive test with the 3-D model has been carried out with a haptic device.

    The ATLAS Education and Outreach Group is in the process of migrating its public online content to a professionally designed set of web pages built on the Drupal content management system. Development of the front-end design passed through several key stages, including audience surveys, stakeholder interviews, usage analytics, and a series of fast design iterations, called sprints. Implementation of the web site involves application of the html design using Drupal templates, refined development iterations, and the overall population of the site with content. We present the design and development processes and share the lessons learned along the way, including the results of the data-driven discovery studies. We also demonstrate the advantages of selecting a back-end supported by content management, with a focus on workflow. Finally, we discuss usage of the new public web pages to implement outreach strategy through implementation of clearly presented themes, consistent audience targeting and messaging, and th...

We used to believe open access simply meant online and free of charge. However, while open-access journals are free to readers, in 2017 authors must make a greater sacrifice in the form of an article-processing charge (APC). Again, while this does not apply to Arthroscopy, the APC will apply to Arthroscopy Techniques.

    Background Individual pharmacokinetic assessment is a critical component of tailored prophylaxis for hemophilia patients. Population pharmacokinetics allows using individual sparse data, thus simplifying individual pharmacokinetic studies. Implementing population pharmacokinetics capacity for the hemophilia community is beyond individual reach and requires a system effort. Objective The Web-Accessible Population Pharmacokinetic Service—Hemophilia (WAPPS-Hemo) project aims to assemble a database of patient pharmacokinetic data for all existing factor concentrates, develop and validate population pharmacokinetics models, and integrate these models within a Web-based calculator for individualized pharmacokinetic estimation in patients at participating treatment centers. Methods Individual pharmacokinetic studies on factor VIII and IX concentrates will be sourced from pharmaceutical companies and independent investigators. All factor concentrate manufacturers, hemophilia treatment centers (HTCs), and independent investigators (identified via a systematic review of the literature) having on file pharmacokinetic data and willing to contribute full or sparse pharmacokinetic data will be eligible for participation. Multicompartmental modeling will be performed using a mixed-model approach for derivation and Bayesian forecasting for estimation of individual sparse data. NONMEM (ICON Development Solutions) will be used as modeling software. Results The WAPPS-Hemo research network has been launched and is currently joined by 30 HTCs from across the world. We have gathered dense individual pharmacokinetic data on 878 subjects, including several replicates, on 21 different molecules from 17 different sources. We have collected sparse individual pharmacokinetic data on 289 subjects from the participating centers through the testing phase of the WAPPS-Hemo Web interface. We have developed prototypal population pharmacokinetics models for 11 molecules. The WAPPS-Hemo website

    The Live Access Server (LAS) is a general purpose Web-server for delivering services related to geo-science data sets. Data providers can use the LAS architecture to build custom Web interfaces to their scientific data. Users and client programs can then access the LAS site to search the provider's on-line data holdings, make plots of data, create sub-sets in a variety of formats, compare data sets and perform analysis on the data. The Live Access server software has continued to evolve by expanding the types of data (in-situ observations and curvilinear grids) it can serve and by taking advantages of advances in software infrastructure both in the earth sciences community (THREDDS, the GrADS Data Server, the Anagram framework and Java netCDF 2.2) and in the Web community (Java Servlet and the Apache Jakarta frameworks). This presentation will explore the continued evolution of the LAS architecture towards a complete Web-services-based framework. Additionally, we will discuss the redesign and modernization of some of the support tools available to LAS installers. Soon after the initial implementation, the LAS architecture was redesigned to separate the components that are responsible for the user interaction (the User Interface Server) from the components that are responsible for interacting with the data and producing the output requested by the user (the Product Server). During this redesign, we changed the implementation of the User Interface Server from CGI and JavaScript to the Java Servlet specification using Apache Jakarta Velocity backed by a database store for holding the user interface widget components. The User Interface server is now quite flexible and highly configurable because we modernized the components used for the implementation. Meanwhile, the implementation of the Product Server has remained a Perl CGI-based system. Clearly, the time has come to modernize this part of the LAS architecture. Before undertaking such a modernization it is

    2016-01-01

    Objective: The present study was designed to assess the quality of Chinese-language Internet-based information on HIV/AIDS. Methods: We entered the following search terms, in Chinese, into Baidu and Sogou: “HIV/AIDS”, “symptoms”, and “treatment”, and evaluated the first 50 hits of each query using the Minervation validation instrument (LIDA tool) and DISCERN instrument. Results: Of the 900 hits identified, 85 websites were included in this study. The overall score of the LIDA tool was 63.7%; the mean score of accessibility, usability, and reliability was 82.2%, 71.5%, and 27.3%, respectively. Of the top 15 sites according to the LIDA score, the mean DISCERN score was calculated at 43.1 (95% confidence intervals (CI) = 37.7–49.5). Noncommercial websites showed higher DISCERN scores than commercial websites; whereas commercial websites were more likely to be found in the first 20 links obtained from each search engine than the noncommercial websites. Conclusions: In general, the HIV/AIDS related Chinese-language websites have poor reliability, although their accessibility and usability are fair. In addition, the treatment information presented on Chinese-language websites is far from sufficient. There is an imperative need for professionals and specialized institutes to improve the comprehensiveness of web-based information related to HIV/AIDS. PMID:27556475

  6. A Data Capsule Framework For Web Services: Providing Flexible Data Access Control To Users

    2010-01-01

    This paper introduces the notion of a secure data capsule, which refers to an encapsulation of sensitive user information (such as a credit card number) along with code that implements an interface suitable for the use of such information (such as charging for purchases) by a service (such as an online merchant). In our capsule framework, users provide their data in the form of such capsules to web services rather than raw data. Capsules can be deployed in a variety of ways, either on a trusted third party or the user's own computer or at the service itself, through the use of a variety of hardware or software modules, such as a virtual machine monitor or trusted platform module: the only requirement is that the deployment mechanism must ensure that the user's data is only accessed via the interface sanctioned by the user. The framework further allows an user to specify policies regarding which services or machines may host her capsule, what parties are allowed to access the interface, and with what parameter...

    Full Text Available Background: Active commuters have lower risk of chronic disease. Understanding which of the, to some extent, modifiable characteristics of public transportation that facilitate its use is thus important in a public health perspective. The aim of the study was to examine the association between individual public transportation accessibility and self-reported active commuting, and whether the associations varied with commute distance, age and gender. Methods: 28,928 commuters in the Capital Region of Denmark reported self-reported time spent either walking or cycling to work or study each day and the distance to work or study. Data were obtained from the Danish National Health Survey collected in February to April 2010. Individual accessibility by public transportation was calculated using a multimodal network in a GIS. Multilevel logistic regression was used to analyze the association between accessibility, expressed as access area, and being an active commuter.Results: Public transport accessibility area based on all stops within walking and cycling distance was positively associated with being an active commuter. Distance to work, age and gender modified the associations. Residing within 10 km commuting distance and in areas of high accessibility was associated with being an active commuter and meeting the recommendations of physical activity. For the respondents above 29 years, Individual public transportation accessibility was positively associated with being an active commuter. Women having high accessibility had significantly higher odds of being an active commuter compared to having a low accessibility. For men the associations were insignificant.Conclusions: This study extends the knowledge about the driving forces of using public transportation for commuting by examining the individual public transportation accessibility. Findings suggest that transportation accessibility supports active commuting and planning of improved public transit

    web services, which significantly contributed to the accessibility of public sector geo-information. The second major impulse was the development of open data policies following the Digital Agenda for Europe adopted in 2010 and the USA Open Government Directive of 2009 and the Digital Agenda for Europe of 2010. These two impulses were the main drivers in Europe to start a careful move from cost recovery policies to open access or open data policies and for more public sector information to be made available as open data. Thus, of the four barriers to re-use of public sector information data cited in Chapter 1 (legal, financial, technical and organisational barriers, two barriers should have been lifted to a large degree due to open data. This shift to open data provided an excellent opportunity to test the hypothesis that the main barriers for re-users of public sector information were indeed restrictive licences and high fees as suggested by earlier research.Chapter 2 showed that by 2008, most European Union Member States had transposed and implemented the 2003/98/EC PSI Directive, however, in various ways and with considerable delay. By 2008, the effects of the PSI Directive were only slowly starting to emerge. A number of Member States reviewed their access policies and more public sector information became available for re-use. Some Member States made the information available free-of-charge or reduced their fees significantly. In many cases, where re-use fees were reduced the number of regular re-users increased significantly and total revenue even increased in spite of lower fees. Although the 2007/2/EC INSPIRE Directive paved the way for technical interoperability by providing guidelines for web services and catalogues, neither the INSPIRE Directive nor the PSI Directive had tackled the issue of legal interoperability. Chapter 2 also demonstrated that a major barrier to creating a level playing field for the private sector was the fact that some public sector

      网络隐蔽信道是将窃取的机密信息隐藏在正常的网络传输协议中的一种通信方法。由于网络时间隐蔽信道不修改网络数据包的内容,因此更加难以检测和限制,从而具有更大的威胁。提出一种新的基于 Web 访问模型的网络时间隐蔽信道,恶意用户通过规律性的访问 Web 服务器实现机密信息传输;实现了该网络隐蔽信道原型,并给出了信道的性能分析结果。%Network covert channel is a transmission scheme which hides the confidential information to normal network channel. Network covert timing channel does not modify the network packets, therefore it is more difficult to detect and more dangerous. This paper presents a new network covert timing channel based on Web access model. Malicious users transfer the confidential information by regularly access the Web server in this channel. We implement the prototype of the covert channel, and analyze the channel performance.

    Highlights: • No matter how large the data is, the response time is always less than 500 milliseconds. • It is intelligent and just gives you the data you want. • It can be accessed directly over the Internet without installing special client software if you already have a browser. • Adopt scale and segment technology to organize data. • To support a new database for the WebScope is quite easy. • With the configuration stored in user’s profile, you have your own portable WebScope. - Abstract: Fusion research is an international collaboration work. To enable researchers across the world to visualize and analyze the experiment data, a web based data access and visualization tool is quite important [1]. Now, a new WebScope based on RIA (Rich Internet Application) is designed and implemented to meet these requirements. On the browser side, a fluent and intuitive interface is provided for researchers at J-TEXT laboratory and collaborators from all over the world to view experiment data and related metadata. The fusion experiments will feature long pulse and high sampling rate in the future. The data access and visualization system in this work has adopted segment and scale concept. Large data samples are re-sampled in different scales and then split into segments for instant response. It allows users to view extremely large data on the web browser efficiently, without worrying about the limitation on the size of the data. The HTML5 and JavaScript based web front-end can provide intuitive and fluent user experience. On the server side, a RESTful (Representational State Transfer) web API, which is based on ASP.NET MVC (Model View Controller), allows users to access the data and its metadata through HTTP (HyperText Transfer Protocol). An interface to the database has been designed to decouple the data access and visualization system from the data storage. It can be applied upon any data storage system like MDSplus or JTEXTDB, and this system is very easy to

  18. The EarthScope Array Network Facility: application-driven low-latency web-based tools for accessing high-resolution multi-channel waveform data

    Science.gov (United States)

    Newman, R. L.; Lindquist, K. G.; Clemesha, A.; Vernon, F. L.

    2008-12-01

    Since April 2004 the EarthScope USArray seismic network has grown to over 400 broadband stations that stream multi-channel data in near real-time to the Array Network Facility in San Diego. Providing secure, yet open, access to real-time and archived data for a broad range of audiences is best served by a series of platform agnostic low-latency web-based applications. We present a framework of tools that interface between the world wide web and Boulder Real Time Technologies Antelope Environmental Monitoring System data acquisition and archival software. These tools provide audiences ranging from network operators and geoscience researchers, to funding agencies and the general public, with comprehensive information about the experiment. This ranges from network-wide to station-specific metadata, state-of-health metrics, event detection rates, archival data and dynamic report generation over a stations two year life span. Leveraging open source web-site development frameworks for both the server side (Perl, Python and PHP) and client-side (Flickr, Google Maps/Earth and jQuery) facilitates the development of a robust extensible architecture that can be tailored on a per-user basis, with rapid prototyping and development that adheres to web-standards.

  19. A web accessible scientific workflow system for vadoze zone performance monitoring: design and implementation examples

    Science.gov (United States)

    Mattson, E.; Versteeg, R.; Ankeny, M.; Stormberg, G.

    2005-12-01

    Long term performance monitoring has been identified by DOE, DOD and EPA as one of the most challenging and costly elements of contaminated site remedial efforts. Such monitoring should provide timely and actionable information relevant to a multitude of stakeholder needs. This information should be obtained in a manner which is auditable, cost effective and transparent. Over the last several years INL staff has designed and implemented a web accessible scientific workflow system for environmental monitoring. This workflow environment integrates distributed, automated data acquisition from diverse sensors (geophysical, geochemical and hydrological) with server side data management and information visualization through flexible browser based data access tools. Component technologies include a rich browser-based client (using dynamic javascript and html/css) for data selection, a back-end server which uses PHP for data processing, user management, and result delivery, and third party applications which are invoked by the back-end using webservices. This system has been implemented and is operational for several sites, including the Ruby Gulch Waste Rock Repository (a capped mine waste rock dump on the Gilt Edge Mine Superfund Site), the INL Vadoze Zone Research Park and an alternative cover landfill. Implementations for other vadoze zone sites are currently in progress. These systems allow for autonomous performance monitoring through automated data analysis and report generation. This performance monitoring has allowed users to obtain insights into system dynamics, regulatory compliance and residence times of water. Our system uses modular components for data selection and graphing and WSDL compliant webservices for external functions such as statistical analyses and model invocations. Thus, implementing this system for novel sites and extending functionality (e.g. adding novel models) is relatively straightforward. As system access requires a standard webbrowser

    2013-02-01

    Full Text Available This study develops a novel method for learning mechatronics using remote monitoring and control, based on a programmable logic controller (PLC and WebAccess. A mechatronics module, a Web‐CAM and a PLC were integrated with WebAccess software to organize a remote laboratory. The proposed system enables users to access the Internet for remote monitoring and control of the mechatronics module via a web browser, thereby enhancing work flexibility by enabling personnel to control mechatronics equipment from a remote location. Mechatronics control and long‐distance monitoring were realized by establishing communication between the PLC and WebAccess. Analytical results indicate that the proposed system is feasible. The suitability of this system is demonstrated in the department of industrial education and technology at National Changhua University of Education, Taiwan. Preliminary evaluation of the system was encouraging and has shown that it has achieved success in helping students understand concepts and master remote monitoring and control techniques.

    2008-07-01

    Full Text Available Abstract 'Mashup' was originally used to describe the mixing together of musical tracks to create a new piece of music. The term now refers to Web sites or services that weave data from different sources into a new data source or service. Using a musical metaphor that builds on the origin of the word 'mashup', this paper presents a demonstration "playlist" of four geo-mashup vignettes that make use of a range of Web 2.0, Semantic Web, and 3-D Internet methods, with outputs/end-user interfaces spanning the flat Web (two-dimensional – 2-D maps, a three-dimensional – 3-D mirror world (Google Earth and a 3-D virtual world (Second Life ®. The four geo-mashup "songs" in this "playlist" are: 'Web 2.0 and GIS (Geographic Information Systems for infectious disease surveillance', 'Web 2.0 and GIS for molecular epidemiology', 'Semantic Web for GIS mashup', and 'From Yahoo! Pipes to 3-D, avatar-inhabited geo-mashups'. It is hoped that this showcase of examples and ideas, and the pointers we are providing to the many online tools that are freely available today for creating, sharing and reusing geo-mashups with minimal or no coding, will ultimately spark the imagination of many public health practitioners and stimulate them to start exploring the use of these methods and tools in their day-to-day practice. The paper also discusses how today's Web is rapidly evolving into a much more intensely immersive, mixed-reality and ubiquitous socio-experiential Metaverse that is heavily interconnected through various kinds of user-created mashups.

  5. CERN Public homepage takes its first step towards web 2.0

    CERN Multimedia

    2009-01-01

    Some of you may have noticed a change of format on the CERN public homepage recently. The Bulletin catches up with Dan Noyes, CERN web content manager, to find out what is happening. With over 7000 websites in the cern.ch domain, CERN’s web landscape is a challenging one to manage. Dan Noyes, who joined CERN a year ago, is the web content manager within the Communication group, which is mandated to develop the public and user websites as well as developing standards and guidelines for the wider CERN web. The recent changes made to the public homepage were the first small step towards some quite major changes proposed for CERN’s websites over the next couple of years. Currently, one of the problems of CERN’s websites is that the quantity and the diversity of the information in them make them difficult to manage, if one wants to avoid duplication and to keep information updated and easy to find. This is also aggravated by the lack of a standard design philosophy a...

  6. Final Technical Report - Publication and Retrieval of Computational Chemical-Physical Data Via the Semantic Web

    Energy Technology Data Exchange (ETDEWEB)

    Ostlund, Neil [Chemical Semantics, Inc.,Gainesville, FL (United States)

    2017-07-20

    This research showed the feasibility of applying the concepts of the Semantic Web to Computation Chemistry. We have created the first web portal (www.chemsem.com) that allows data created in the calculations of quantum chemistry, and other such chemistry calculations to be placed on the web in a way that makes the data accessible to scientists in a semantic form never before possible. The semantic web nature of the portal allows data to be searched, found, and used as an advance over the usual approach of a relational database. The semantic data on our portal has the nature of a Giant Global Graph (GGG) that can be easily merged with related data and searched globally via a SPARQL Protocol and RDF Query Language (SPARQL) that makes global searches for data easier than with traditional methods. Our Semantic Web Portal requires that the data be understood by a computer and hence defined by an ontology (vocabulary). This ontology is used by the computer in understanding the data. We have created such an ontology for computational chemistry (purl.org/gc) that encapsulates a broad knowledge of the field of computational chemistry. We refer to this ontology as the Gainesville Core. While it is perhaps the first ontology for computational chemistry and is used by our portal, it is only a start of what must be a long multi-partner effort to define computational chemistry. In conjunction with the above efforts we have defined a new potential file standard (Common Standard for eXchange – CSX for computational chemistry data). This CSX file is the precursor of data in the Resource Description Framework (RDF) form that the semantic web requires. Our portal translates CSX files (as well as other computational chemistry data files) into RDF files that are part of the graph database that the semantic web employs. We propose a CSX file as a convenient way to encapsulate computational chemistry data.

    2016-12-01

    The National Deep Submergence Facility (NDSF) operates the Human Occupied Vehicle (HOV) Alvin, the Remotely Operated Vehicle (ROV) Jason, and the Autonomous Underwater Vehicle (AUV) Sentry. These vehicles are deployed throughout the global oceans to acquire sensor data and physical samples for a variety of interdisciplinary science programs. As part of the EarthCube Integrative Activity Alliance Testbed Project (ATP), new web services were developed to improve access to existing online NDSF data and metadata resources. These services make use of tools and infrastructure developed by the Interdisciplinary Earth Data Alliance (IEDA) and enable programmatic access to metadata and data resources as well as the development of new service-driven user interfaces. The Alvin Frame Grabber and Jason Virtual Van enable the exploration of frame-grabbed images derived from video cameras on NDSF dives. Metadata available for each image includes time and vehicle position, data from environmental sensors, and scientist-generated annotations, and data are organized and accessible by cruise and/or dive. A new FrameGrabber web service and service-driven user interface were deployed to offer integrated access to these data resources through a single API and allows users to search across content curated in both systems. In addition, a new NDSF Dive Metadata web service and service-driven user interface was deployed to provide consolidated access to basic information about each NDSF dive (e.g. vehicle name, dive ID, location, etc), which is important for linking distributed data resources curated in different data systems.

    2005-04-01

    In 2001, the Centers for Disease Control and Prevention funded three Centers for Genomics and Public Health to develop training tools for increasing genomic awareness. Over the past three years, the centers, working together with the Centers for Disease Control and Prevention's Office of Genomics and Disease Prevention, have developed tools to increase awareness of the impact genomics will have on public health practice, to provide a foundation for understanding basic genomic advances, and to translate the relevance of that information to public health practitioners' own work. These training tools serve to communicate genomic advances and their potential for integration into public heath practice. This paper highlights two of these training tools: 1) Genomics for Public Health Practitioners: The Practical Application of Genomics in Public Health Practice, a Web-based introduction to genomics, and 2) Six Weeks to Genomic Awareness, an in-depth training module on public health genomics. This paper focuses on the processes and collaborative efforts by which these live presentations were developed and delivered as Web-based training sessions.

  11. Global Location-Based Access to Web Applications Using Atom-Based Automatic Update

    Science.gov (United States)

    Singh, Kulwinder; Park, Dong-Won

    We propose an architecture which enables people to enquire about information available in directory services by voice using regular phones. We implement a Virtual User Agent (VUA) which mediates between the human user and a business directory service. The system enables the user to search for the nearest clinic, gas station by price, motel by price, food / coffee, banks/ATM etc. and fix an appointment, or automatically establish a call between the user and the business party if the user prefers. The user also has an option to receive appointment confirmation by phone, SMS, or e-mail. The VUA is accessible by a toll free DID (Direct Inward Dialing) number using a phone by anyone, anywhere, anytime. We use the Euclidean formula for distance measurement. Since, shorter geodesic distances (on the Earth’s surface) correspond to shorter Euclidean distances (measured by a straight line through the Earth). Our proposed architecture uses Atom XML syndication format protocol for data integration, VoiceXML for creating the voice user interface (VUI) and CCXML for controlling the call components. We also provide an efficient algorithm for parsing Atom feeds which provide data to the system. Moreover, we describe a cost-effective way for providing global access to the VUA based on Asterisk (an open source IP-PBX). We also provide some information on how our system can be integrated with GPS for locating the user coordinates and therefore efficiently and spontaneously enhancing the system response. Additionally, the system has a mechanism for validating the phone numbers in its database, and it updates the number and other information such as daily price of gas, motel etc. automatically using an Atom-based feed. Currently, the commercial directory services (Example 411) do not have facilities to update the listing in the database automatically, so that why callers most of the times get out-of-date phone numbers or other information. Our system can be integrated very easily

  12. A revaluation of the cultural dimension of disability policy in the European Union: the impact of digitization and web accessibility.

    Ferri, Delia; Giannoumis, G Anthony

    2014-01-01

    Reflecting the commitments undertaken by the EU through the conclusion of the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD), the European Disability Strategy 2010–2020 not only gives a prominent position to accessibility, broadly interpreted, but also suggests an examination of the obligations for access to cultural goods and services. The European Disability Strategy 2010–2020 expressly acknowledges that EU action will support national activities to make sports, leisure, cultural and recreational organizations and activities accessible, and use the possibilities for copyright exceptions in the Directive 2001/29/EC (Infosoc Directive). This article discusses to what extent the EU has realized the principle of accessibility and the right to access cultural goods and services envisaged in the UNCRPD. Previous research has yet to explore how web accessibility and digitization interact with the cultural dimension of disability policy in the European Union. This examination attempts to fill this gap by discussing to what extent the European Union has put this cultural dimension into effect and how web accessibility policies and the digitization of cultural materials influence these efforts.

    Willinsky, John; Maggio, Lauren

    2011-01-01

    Background In 2008, the National Institutes of Health (NIH) Public Access Policy mandated open access for publications resulting from NIH funding (following a 12-month embargo). The large increase in access to research that will take place in the years to come has potential implications for evidence-based practice (EBP) and lifelong learning for health personnel. Objective This study assesses health personnel’s current use of research to establish whether grounds exist for expecting, preparing for, and further measuring the impact of the NIH Public Access Policy on health care quality and outcomes in light of time constraints and existing information resources. Methods In all, 14 interviews and 90 surveys of health personnel were conducted at a community-based clinic and an independent teaching hospital in 2010. Health personnel were asked about the research sources they consulted and the frequency with which they consulted these sources, as well as motivation and search strategies used to locate articles, perceived level of access to research, and knowledge of the NIH Public Access Policy. Results In terms of current access to health information, 65% (57/88) of the health personnel reported being satisfied, while 32% (28/88) reported feeling underserved. Among the sources health personnel reported that they relied upon and consulted weekly, 83% (73/88) reported turning to colleagues, 77% (67/87) reported using synthesized information resources (eg, UpToDate and Cochrane Systematic Reviews), while 32% (28/88) reported that they consulted primary research literature. The dominant resources health personnel consulted when actively searching for health information were Google and Wikipedia, while 27% (24/89) reported using PubMed weekly. The most prevalent reason given for accessing research on a weekly basis, reported by 35% (31/88) of survey respondents, was to help a specific patient, while 31% (26/84) were motivated by general interest in research. Conclusions

    Both global area coverage (GAC) and high-resolution picture transmission (HRTP) data from the Advanced Very High Resolution Radiometer (AVHRR) are made available to laternet users through an online data access system. Older GOES-7 data am also available. Created as a "testbed" data system for NASA's future Earth Observing System Data and Information System (EOSDIS), this testbed provides an opportunity to test both the technical requirements of an onune'd;ta system and the different ways in which the -general user, community would employ such a system. Initiated in December 1991, the basic data system experienced five major evolutionary changes In response to user requests and requirements. Features added with these changes were the addition of online browse, user subsetting, dynamic image Processing/navigation, a stand-alone data storage system, and movement,from an X-windows graphical user Interface (GUI) to a World Wide Web (WWW) interface. Over Its lifetime, the system has had as many as 2500 registered users. The system on the WWW has had over 2500 hits since October 1995. Many of these hits are by casual users that only take the GIF images directly from the interface screens and do not specifically order digital data. Still, there b a consistent stream of users ordering the navigated image data and related products (maps and so forth). We have recently added a real-time, seven- day, northwestern United States normalized difference vegetation index (NDVI) composite that has generated considerable Interest. Index Terms-Data system, earth science, online access, satellite data.

  17. MATISSE a web-based tool to access, visualize and analyze high resolution minor bodies observation

    2016-07-01

    In the recent years planetary exploration missions acquired data from minor bodies (i.e., dwarf planets, asteroid and comets) at a detail level never reached before. Since these objects often present very irregular shapes (as in the case of the comet 67P Churyumov-Gerasimenko target of the ESA Rosetta mission) "classical" bidimensional projections of observations are difficult to understand. With the aim of providing the scientific community a tool to access, visualize and analyze data in a new way, ASI Science Data Center started to develop MATISSE (Multi-purposed Advanced Tool for the Instruments for the Solar System Exploration - http://tools.asdc.asi.it/matisse.jsp) in late 2012. This tool allows 3D web-based visualization of data acquired by planetary exploration missions: the output could either be the straightforward projection of the selected observation over the shape model of the target body or the visualization of a high-order product (average/mosaic, difference, ratio, RGB) computed directly online with MATISSE. Standard outputs of the tool also comprise downloadable files to be used with GIS software (GeoTIFF and ENVI format) and 3D very high-resolution files to be viewed by means of the free software Paraview. During this period the first and most frequent exploitation of the tool has been related to visualization of data acquired by VIRTIS-M instruments onboard Rosetta observing the comet 67P. The success of this task, well represented by the good number of published works that used images made with MATISSE confirmed the need of a different approach to correctly visualize data coming from irregular shaped bodies. In the next future the datasets available to MATISSE are planned to be extended, starting from the addition of VIR-Dawn observations of both Vesta and Ceres and also using standard protocols to access data stored in external repositories, such as NASA ODE and Planetary VO.

    Full Text Available The risk of adverse pregnancy outcomes can be minimized through the adoption of healthy lifestyles before pregnancy by women of childbearing age. Initiatives for promotion of preconception health may be difficult to implement. Internet can be used to build tailored health interventions through identification of the public's information needs. To this aim, we developed a semi-automatic web-based system for monitoring Google searches, web pages and activity on social networks, regarding preconception health.Based on the American College of Obstetricians and Gynecologists guidelines and on the actual search behaviors of Italian Internet users, we defined a set of keywords targeting preconception care topics. Using these keywords, we analyzed the usage of Google search engine and identified web pages containing preconception care recommendations. We also monitored how the selected web pages were shared on social networks. We analyzed discrepancies between searched and published information and the sharing pattern of the topics.We identified 1,807 Google search queries which generated a total of 1,995,030 searches during the study period. Less than 10% of the reviewed pages contained preconception care information and in 42.8% information was consistent with ACOG guidelines. Facebook was the most used social network for sharing. Nutrition, Chronic Diseases and Infectious Diseases were the most published and searched topics. Regarding Genetic Risk and Folic Acid, a high search volume was not associated to a high web page production, while Medication pages were more frequently published than searched. Vaccinations elicited high sharing although web page production was low; this effect was quite variable in time.Our study represent a resource to prioritize communication on specific topics on the web, to address misconceptions, and to tailor interventions to specific populations.

    Full Text Available The present study investigates the extent of utilization of two meta tags – “keywords” and “descriptors” – in Web-based Open-Access Journals. A sample composed of 707 journals taken from DOAJ was used. These were analyzed on the account of utilization of the said meta tags. Findings demonstrated that these journals utilized “keywords” and “descriptors” meta-tags, 33.1% and 29.9% respectively. It was further demonstrated that among various subject classifications, “General Journals” had been the highest while “Mathematics and Statistics Journals” had the least utilization as “keywords” meta-tags. Moreover, “General Journals” and “Chemistry journals”, with 55.6% and 15.4% utilization respectively, had the highest and the lowest “descriptors” meta-tag usage rate. Based on our findings, and when compared against other similar research findings, there had been no significant growth experienced in utilization of these meta tags.

    Large scale space programs analyze thousands of requirements while mitigating safety, performance, schedule, and cost risks. These efforts involve a variety of roles with interdependent use cases and goals. For example, study managers and facilitators identify ground-rules and assumptions for a collection of studies required for a program or project milestone. Task leaders derive product requirements from the ground rules and assumptions and describe activities to produce needed analytical products. Disciplined specialists produce the specified products and load results into a file management system. Organizational and project managers provide the personnel and funds to conduct the tasks. Each role has responsibilities to establish information linkages and provide status reports to management. Projects conduct design and analysis cycles to refine designs to meet the requirements and implement risk mitigation plans. At the program level, integrated design and analysis cycles studies are conducted to eliminate every 'to-be-determined' and develop plans to mitigate every risk. At the agency level, strategic studies analyze different approaches to exploration architectures and campaigns. This paper describes a web-accessible database developed by NASA to coordinate and manage tasks at three organizational levels. Other topics in this paper cover integration technologies and techniques for process modeling and enterprise architectures.

  5. Human membrane transporter database: a Web-accessible relational database for drug transport studies and pharmacogenomics.

    Yan, Q; Sadée, W

    2000-01-01

    The human genome contains numerous genes that encode membrane transporters and related proteins. For drug discovery, development, and targeting, one needs to know which transporters play a role in drug disposition and effects. Moreover, genetic polymorphisms in human membrane transporters may contribute to interindividual differences in the response to drugs. Pharmacogenetics, and, on a genome-wide basis, pharmacogenomics, address the effect of genetic variants on an individual's response to drugs and xenobiotics. However, our knowledge of the relevant transporters is limited at present. To facilitate the study of drug transporters on a broad scale, including the use of microarray technology, we have constructed a human membrane transporter database (HMTD). Even though it is still largely incomplete, the database contains information on more than 250 human membrane transporters, such as sequence, gene family, structure, function, substrate, tissue distribution, and genetic disorders associated with transporter polymorphisms. Readers are invited to submit additional data. Implemented as a relational database, HMTD supports complex biological queries. Accessible through a Web browser user interface via Common Gateway Interface (CGI) and Java Database Connection (JDBC), HMTD also provides useful links and references, allowing interactive searching and downloading of data. Taking advantage of the features of an electronic journal, this paper serves as an interactive tutorial for using the database, which we expect to develop into a research tool.

    Information on mutations in human hemoglobin is important in many efforts, including understanding the pathophysiology of hemoglobin diseases, developing therapies, elucidating the dynamics of sequence alterations inhuman populations, and dissecting the details of protein structure/function relationships. Currently, information is available on a large number of mutations and variants, but is distributed among thousands of papers. In an effort to organize this voluminous data set, two Syllabi have been prepared compiling succinct information on human hemoglobin abnormalities. In both of these, each entry provides amino acid and/or DNA sequence alterations, hematological and clinical data, methodology used for characterization, ethnic distribution, and functional properties and stability of the hemoglobin, together with appropriate literature references. A Syllabus of Human Hemoglobin Variants (1996) describes 693 abnormal hemoglobins resulting from alterations in the alpha-, beta-, gamma-, and delta-globin chains, including special abnormalities such as double mutations, hybrid chains, elongated chains, deletions, and insertions. We have converted this resource to an electronic form that is accessible via the World Wide Web at the Globin Gene Server (http://globin.cse.psu.edu). Hyperlinks are provided from each entry in the tables of variants to the corresponding full description. In addition, a simple query interface allows the user to find all entries containing a designated word or phrase. We are in the process of converting A Syllabus of Thalassemia Mutations (1997) to a similar electronic format.

    Content-based image retrieval (CBIR) is the process of retrieving images by directly using image visual characteristics. In this paper, we present a prototype system implemented for CBIR for a uterine cervix image (cervigram) database. This cervigram database is a part of data collected in a multi-year longitudinal effort by the National Cancer Institute (NCI), and archived by the National Library of Medicine (NLM), for the study of the origins of, and factors related to, cervical precancer/cancer. Users may access the system with any Web browser. The system is built with a distributed architecture which is modular and expandable; the user interface is decoupled from the core indexing and retrieving algorithms, and uses open communication standards and open source software. The system tries to bridge the gap between a user's semantic understanding and image feature representation, by incorporating the user's knowledge. Given a user-specified query region, the system returns the most similar regions from the database, with respect to attributes of color, texture, and size. Experimental evaluation of the retrieval performance of the system on "groundtruth" test data illustrates its feasibility to serve as a possible research tool to aid the study of the visual characteristics of cervical neoplasia.

    Gene Wiki Plus (GeneWiki+) and the Online Mendelian Inheritance in Man (OMIM) are publicly available resources for sharing information about disease-gene and gene-SNP associations in humans. While immensely useful to the scientific community, both resources are manually curated, thereby making the data entry and publication process time-consuming, and to some degree, error-prone. To this end, this study investigates Semantic Web technologies to validate existing and potentially discover new genotype-phenotype associations in GWP and OMIM. In particular, we demonstrate the applicability of SPARQL queries for identifying associations not explicitly stated for commonly occurring chronic diseases in GWP and OMIM, and report our preliminary findings for coverage, completeness, and validity of the associations. Our results highlight the benefits of Semantic Web querying technology to validate existing disease-gene associations as well as identify novel associations although further evaluation and analysis is required before such information can be applied and used effectively.

  9. Analysis of Croatian archives' web page from the perspective of public programmes

    2015-04-01

    Full Text Available In order to remain relevant in society, archivists should promote collections and records that are kept in the archives. Through public programmes, archives interact with customers and various public actors and create the institutional image. This paper is concerned with the role of public programmes in the process of modernization of the archival practice, with the emphasis on the Croatian state archives. The aim of the paper is to identify what kind of information is offered to users and public in general on the web sites of the Croatian state archives. Public programmes involve two important components of archival practice: archives and users. Therefore, public programmes ensure good relations with the public. Croatian archivists still question the need for public relations in archives, while American and European archives have already integrated public relations into the basic archival functions. The key components needed for successful planning and implementation of public programs are the source of financing, compliance with the annual work plan, clear goals, defined target audience, cooperation and support from the local community, and the evaluation of results.

  11. ProtSA: a web application for calculating sequence specific protein solvent accessibilities in the unfolded ensemble

    Directory of Open Access Journals (Sweden)

    Blackledge Martin

    2009-04-01

    Full Text Available Abstract Background The stability of proteins is governed by the heat capacity, enthalpy and entropy changes of folding, which are strongly correlated to the change in solvent accessible surface area experienced by the polypeptide. While the surface exposed in the folded state can be easily determined, accessibilities for the unfolded state at the atomic level cannot be obtained experimentally and are typically estimated using simplistic models of the unfolded ensemble. A web application providing realistic accessibilities of the unfolded ensemble of a given protein at the atomic level will prove useful. Results ProtSA, a web application that calculates sequence-specific solvent accessibilities of the unfolded state ensembles of proteins has been developed and made freely available to the scientific community. The input is the amino acid sequence of the protein of interest. ProtSA follows a previously published calculation protocol which uses the Flexible-Meccano algorithm to generate unfolded conformations representative of the unfolded ensemble of the protein, and uses the exact analytical software ALPHASURF to calculate atom solvent accessibilities, which are averaged on the ensemble. Conclusion ProtSA is a novel tool for the researcher investigating protein folding energetics. The sequence specific atom accessibilities provided by ProtSA will allow obtaining better estimates of the contribution of the hydrophobic effect to the free energy of folding, will help to refine existing parameterizations of protein folding energetics, and will be useful to understand the influence of point mutations on protein stability.

    2006-01-01

    Full Text Available Introduction. This paper reports preliminary research in a primarily experimental study of how the general public search for information on the Web. The focus is on the query transformation patterns that characterise searching. Method. In this work, we have used transaction logs from the Excite search engine to develop methods for analysing query transformations that should aid the analysis of our ongoing experimental work. Our methods involve the use of similarity techniques to link queries with the most similar previous query in a train. The resulting query transformations are represented as a list of codes representing a whole search. Analysis. It is shown how query transformation sequences can be represented as graphical networks and some basic statistical results are shown. A correlation analysis is performed to examine the co-occurrence of Boolean and quotation mark changes with the syntactic changes. Results. A frequency analysis of the occurrence of query transformation codes is presented. The connectivity of graphs obtained from the query transformation is investigated and found to follow an exponential scaling law. The correlation analysis reveals a number of patterns that provide some interesting insights into Web searching by the general public. Conclusion. We have developed analytical methods based on query similarity that can be applied to our current experimental work with volunteer subjects. The results of these will form part of a database with the aim of developing an improved understanding of how the public search the Web.

  14. Troubling fragments and small stories: an analysis of public commentary on nursing through a web blog.

    Hutchinson, Marie; Jackson, Debra

    2014-01-01

    In recent years the media in the United Kingdom has engaged in intense debate on standards of nursing care in the National Health Service (NHS). Much of the public engagement with this debate has been carried out through social media, including blogs and micro blogs. In this manuscript we analyse a single episode of public commentary appearing on a web blog about standards of nursing in the NHS. The blog entries featured brief stories and fragments of stories about care experiences, and perceptions of nursing care. Content analysis of the published narratives identified a troubling undercurrent of indifference experienced by patients, clients and their families. These stories represent a counter narrative to contemporary grand narratives of nursing, and as such, they sit on the outer edges of contemporary professional discourse. Increasing use of social media such as web blogs provides patients and carers with a public forum for comment that makes failures (or perceived failures) more visible to more people. Web blogs provide an important new mechanism through which patients and carers can have a voice about their own experiences of nursing care, and wider health care.

    Previous research has shown that compared to mental representations of others, mental representations of ourselves are characterized by relatively greater accessibility of private, unobservable content, as opposed to content that is public and observable. Are those differences preserved when individuals focus on their own public selves and/or on private selves of others? Participants were asked to make social judgments involving traits that, in their view, were highly descriptive of either public or private selves of themselves, their best friend, or an acquaintance. Results demonstrated that highly self-descriptive traits were more accessible in social judgments involving individuals' private rather than public selves. This was true not only for traits descriptive of one's private self but also for traits descriptive of one's public self. Furthermore, other-descriptive traits, including traits that were highly descriptive of representations of private selves of others, were more accessible in social judgments involving public rather than private selves.

    Full Text Available Abstract Background Target identification is important for modern drug discovery. With the advances in the development of molecular docking, potential binding proteins may be discovered by docking a small molecule to a repository of proteins with three-dimensional (3D structures. To complete this task, a reverse docking program and a drug target database with 3D structures are necessary. To this end, we have developed a web server tool, TarFisDock (Target Fishing Docking http://www.dddc.ac.cn/tarfisdock, which has been used widely by others. Recently, we have constructed a protein target database, Potential Drug Target Database (PDTD, and have integrated PDTD with TarFisDock. This combination aims to assist target identification and validation. Description PDTD is a web-accessible protein database for in silico target identification. It currently contains >1100 protein entries with 3D structures presented in the Protein Data Bank. The data are extracted from the literatures and several online databases such as TTD, DrugBank and Thomson Pharma. The database covers diverse information of >830 known or potential drug targets, including protein and active sites structures in both PDB and mol2 formats, related diseases, biological functions as well as associated regulating (signaling pathways. Each target is categorized by both nosology and biochemical function. PDTD supports keyword search function, such as PDB ID, target name, and disease name. Data set generated by PDTD can be viewed with the plug-in of molecular visualization tools and also can be downloaded freely. Remarkably, PDTD is specially designed for target identification. In conjunction with TarFisDock, PDTD can be used to identify binding proteins for small molecules. The results can be downloaded in the form of mol2 file with the binding pose of the probe compound and a list of potential binding targets according to their ranking scores. Conclusion PDTD serves as a comprehensive and

    2008-01-01

    Many people may search for information about tobacco use, the largest cause of preventable mortality in the United States, on the Internet. In 1999, Philip Morris U.S.A. (PM), the country's biggest cigarette manufacturer, posted a Web site and launched a campaign to encourage people to obtain information about tobacco and health issues there. The company asserted that its goal was to deliver the messages of the public health community about tobacco. However, internal tobacco company documents reveal that the site was a public relations effort intended to help the company avoid punishment and regulation. Examination of the language on the Web site reveals many contradictions and omissions that may undermine public health messages. Among these are vague and confusing information about addiction, tar, and nicotine, a lack of motivators to quit smoking, and silence about tobacco-related mortality. By appearing to join with public health organizations in disseminating "responsible" messages about tobacco, PM may improve its image, thus facilitating its ability to continue to sell its lethal products. Public health nurses should be prepared to examine health information on the Internet for subtle biases, to counter PM's specific language about smoking to patients, and to challenge PM's larger corporate goals.

    Andersson, Jonas E; Skehan, Terry

    2016-01-01

    In Sweden, governmental agencies and bodies are required to implement a higher level of accessibility in their buildings than that stipulated by the National Building and Planning Act (PBL). The Swedish Agency for Participation (MFD, Myndigheten för delaktighet) develops holistic guidelines in order to conceptualize this higher level of accessibility. In conjunction to these guidelines, various checklist protocols have been produced. The present study focuses on the efficiency of such checklist protocols. The study revolved around the use of a checklist protocol in assessments of two buildings in Stockholm: the new head office for the National Authority for Social Insurances (ASI) and the School of Architecture at the Royal Institute of Technology (KTH). The study included three groups: Group 1 and Group 2 consisted of 50 real estate managers employed by the ASI, while Group 3 consisted of three participants in a course at the KTH. The results were similar in all of the groups. The use of the checklist protocol generated queries, which related mainly to two factors: (1) the accompanying factsheet consisted of textual explanations with no drawings, photographs or illustrations and (2) the order of the questions in the checklist protocol was difficult to correlate with the two buildings' spatial logic of accessing, egressing and making use of the built space.

    Full Text Available Active commuting provides routine-based regular physical activity which can reduce the risk of chronic diseases. Using public transportation involves some walking or cycling to a transit stop, transfers and a walk to the end location and users of public transportation have been found to accumulate more moderate physical activity than non-users. Understanding how public transportation characteristics are associated with active transportation is thus important from a public health perspective. This study examines the associations between objective measures of access to public transportation and self-reported active commuting. Self-reported time spent either walking or cycling commuting each day and the distance to workplace were obtained for adults aged 16 to 65 in the Danish National Health Survey 2010 (n = 28,928. Access to public transportation measures were computed by combining GIS-based road network distances from home address to public transit stops an integrating their service level. Multilevel logistic regression was used to examine the association between access to public transportation measures and active commuting. Distance to bus stop, density of bus stops, and number of transport modes were all positively associated with being an active commuter and with meeting recommendations of physical activity. No significant association was found between bus services at the nearest stop and active commuting. The results highlight the importance of including detailed measurements of access to public transit in order to identify the characteristics that facilitate the use of public transportation and active commuting.

    2016-03-01

    Full Text Available Public transport plays a critical role in the sustainability of urban settings. The mass mobility and quality of urban lives can be improved by establishing public transport networks that are accessible to pedestrians within a reasonable walking distance. Accessibility to public transport is characterized by the ease with which inhabitants can reach means of transportation such as buses or metros. By measuring the degree of accessibility to public transport networks using a common data format, a comparative study can be conducted between different cities or metropolitan areas with different public transit systems. The General Transit Feed Specification (GTFS by Google Developers allows this by offering a common format based on text files and sharing the data set voluntarily produced and contributed by the public transit agencies of many participating cities around the world. This paper suggests a method to assess and compare public transit accessibility in different urban areas using the GTFS feed and demographic data. To demonstrate the value of the new method, six examples of metropolitan areas and their public transit accessibility are presented and compared.

Integrated dog population management (DPM) programs, based on the availability of information systems providing reliable data on the structure and composition of the existing dog population in a given area, are fundamental for making realistic plans for any disease surveillance and action system. Traceability systems, based on the compulsory electronic identification of dogs and their registration in a computerised database, are one of the most effective ways to ensure the usefulness of DPM programs. Even if this approach provides many advantages, several areas of improvement have emerged in countries where it has been applied. In Italy, every region hosts its own dog register but these are not compatible with one another. This paper shows the advantages of a web-based-application to improve data management of dog regional registers. The approach used for building this system was inspired by farm animal traceability schemes and it relies on a network of services that allows multi-channel access by different devices and data exchange via the web with other existing applications, without changing the pre-existing platforms. Today the system manages a database for over 300,000 dogs registered in three different Italian regions. By integrating multiple Web Services, this approach could be the solution to gather data at national and international levels at reasonable cost and creating a traceability system on a large scale and across borders that can be used for disease surveillance and development of population management plans.

  16. Perceived Accessibility of Public Transport as a Potential Indicator of Social Inclusion

    2016-06-01

    Full Text Available Perceived accessibility has been acknowledged as an important aspect of transport policy since the 70s. Nevertheless, very few empirical studies have been conducted in this field. When aiming to improve social inclusion, by making sustainable transport modes accessible to all, it is important to understand the factors driving perceived accessibility. Unlike conventional accessibility measures, perceived accessibility focuses on the perceived possibilities and ease of engaging in preferred activities using different transport modes. We define perceived accessibility in terms of how easy it is to live a satisfactory life with the help of the transport system, which is not necessarily the same thing as the objective standard of the system. According to previous research, perceived accessibility varies with the subjectively-rated quality of the mode of transport. Thus, improvements in quality (e.g. trip planning, comfort, or safety increase the perceived accessibility and make life easier to live using the chosen mode of transport. This study (n=750 focuses on the perceived accessibility of public transport, captured using the Perceived Accessibility Scale PAC (Lättman, Olsson, & Friman, 2015. More specifically, this study aims to determine how level of quality affects the perceived accessibility in public transport. A Conditional Process Model shows that, in addition to quality, feeling safe and frequency of travel are important predictors of perceived accessibility. Furthermore, elderly and those in their thirties report a lower level of perceived accessibility to their day-to-day activities using public transport. The basic premise of this study is that subjective experiences may be as important as objective indicators when planning and designing for socially inclusive transport systems.

    Transboundary and cross-catchment access to hydrological data is the key to designing successful environmental policies and activities. Electronic maps based on distributed databases are fundamental for planning and decision making in all regions and for all spatial and temporal scales. Freshwater is an essential asset in New Zealand (and globally) and the availability as well as accessibility of hydrological information held by or held for public authorities and businesses are becoming a crucial management factor. Access to and visual representation of environmental information for the public is essential for attracting greater awareness of water quality and quantity matters. Detailed interdisciplinary knowledge about the environment is required to ensure that the environmental policy-making community of New Zealand considers regional and local differences of hydrological statuses, while assessing the overall national situation. However, cross-regional and inter-agency sharing of environmental spatial data is complex and challenging. In this article, we firstly provide an overview of the state of the art standard compliant techniques and methodologies for the practical implementation of simple, measurable, achievable, repeatable, and time-based (SMART) hydrological data management principles. Secondly, we contrast international state of the art data management developments with the present status for groundwater information in New Zealand. Finally, for the topics (i) data access and harmonisation, (ii) sensor web enablement and (iii) metadata, we summarise our findings, provide recommendations on future developments and highlight the specific advantages resulting from a seamless view, discovery, access, and analysis of interoperable hydrological information and metadata for decision making.

    The ATLAS Education and Outreach Group is in the process of migrating its public online content to a professionally designed set of web pages built on the Drupal [1] content management system. Development of the front-end design passed through several key stages, including audience surveys, stakeholder interviews, usage analytics, and a series of fast design iterations, called sprints. Implementation of the web site involves application of the html design using Drupal templates, refined development iterations, and the overall population of the site with content. We present the design and development processes and share the lessons learned along the way, including the results of the data-driven discovery studies. We also demonstrate the advantages of selecting a back-end supported by content management, with a focus on workflow. Finally, we discuss usage of the new public web pages to implement outreach strategy through implementation of clearly presented themes, consistent audience targeting and messaging, and the enforcement of a well-defined visual identity.

    2005-01-01

    Wildlife populations across the United States are benefiting from improved wildlife management techniques. However, these benefits also create new challenges including overpopulation, disease, increased winter kill, and forage degradation. These issues have become the challenges for natural resource managers and landowners. Specifically, elk (Cervus elaphus) populations in the Gunnison River Valley of Colorado are growing and causing increased resource damage on public and private lands. On public lands elk threaten sage grouse habitat and compete with domestic livestock for available forage; on private lands they diminish available livestock forage. Management of elk and elk habitat in this area is a shared responsibility of the NPS (Black Canyon of the Gunnison National Park and Curecanti National Recreation Area), BLM (Uncompahgre Field Office), USFS (Gunnison National Forest), and the CDOW (Colorado Division of Wildlife). All of these agencies participate in this research and adaptive management project.

  3. Winter: Public Enemy #1 for Accessibility EXPLORING NEW SOLUTIONS

    Directory of Open Access Journals (Sweden)

    Ernesto Morales

    2014-05-01

    Full Text Available Abstract: Winter is expensive. For countries situated in the northern hemisphere, closer to the north pole, such as Canada, Russia and Scandinavia, winter requires the acquisition of special clothing, car tires, and sports equipment, snow removal or plowing from the streets, and is associated with the presence of ice patches, along with accidents and illnesses associated with cold weather. Fall-related injuries due to winter conditions have been estimated to cost the Canadian health care system $ 2.8 billion a year. However, the greatest cost snow entails every year is the social isolation of seniors as well as wheelchair and walker users. This results from the lack of accessibility, as it is difficult to circulate on snow-covered streets even for the able-bodied. Social isolation has been associated with other negative consequences such as depression and even suicide. This exploratory pilot study aimed at finding possible and feasible design solutions for improving the accessibility of sidewalks during winter conditions. For this project we used a Co-Design methodology. Stakeholders (City of Quebec representatives, designers, urban planners, occupational therapists, and adults with motor, visual and aural disabilities were invited to participate in the design process. In order to meet the objectives, two main steps were carried out: 1. Conception of the design solutions (through Co-design sessions in a Focus-group format with seniors, designers and researchers; and 2. Validation of the design solutions (consultation with experts and stakeholders. The results are a wide variety of possible and feasible solutions, including the reorganisation of the snow-removal procedure and the development of heated curb cuts. This project was funded by the City of Quebec in partnership with the Centre interdisciplinaire de recherche en réadaptation et intégration sociale (CIRRIS. Ultimately, the project sought to explore possible solutions to be implemented

    Full Text Available There are several indicators that distinguish an academic discipline, including journals, conferences, and graduate programs. One of them is the presence of academic publications in well-regarded citation indices such as Web of Science (WoS. This study explored the bibliometric characteristics of publications on “second language writing” (SLW covered in the Social Sciences Citation Index and the Arts & Humanities Citation Index of WoS. We found that, while the first appeared in 1992 with a steady increase in recent years, there were a total of 266 SLW publications, mostly in the linguistics research area (92%, in the WoS between 1900 and 2013. The publications included articles, book reviews, and bibliographies written by 1.64 authors per publication, suggesting a low level of collaborations among SLW scholars. They cited 31.44 publications and received citations from 5.90 publications on average. An average SLW title had 2.49 different words and a total of 10.85 words, with an abstract of about five sentences and about six keywords and diverse topics including second language writing, writing, academic writing, error correction, and plagiarism. Our findings will be of value to second language writing scholars, graduate students, and practitioners for examining the status of their field.

    In order to actualize the social sharing and service of the emergency-response information for sudden pollution accidents, the public can share the risk source information service, dangerous goods control technology service and so on, The SQL Server and ArcSDE software are used to establish a spatial database to restore all kinds of information including risk sources, hazardous chemicals and handling methods in case of accidents. Combined with Chinese atmospheric environmental assessment standards, the SCREEN3 atmospheric dispersion model and one-dimensional liquid diffusion model are established to realize the query of related information and the display of the diffusion effect under B/S structure. Based on the WebGIS technology, C#.Net language is used to develop the sudden environmental pollution public service platform. As a result, the public service platform can make risk assessments and provide the best emergency processing services.

  6. Public access defibrillators and fire extinguishers: are comparisons reasonable?

    Science.gov (United States)

    Mell, Howard K; Sayre, Michael R

    2008-01-01

    Sudden cardiac death is a major cause of mortality in the United States of America (Circulation 2008;117:e25-146) with approximately 310000 deaths related to coronary heart disease occurring in emergency departments or in the prehospital environment annually. Several organizations have directed resources toward the treatment of sudden cardiac arrest through a paradigm that has come to be known as the "chain of survival"-prompt activation of emergency response by telephone 911, early bystander cardiopulmonary resuscitation, early defibrillation, and timely advanced cardiac life support (Circulation 1991;83:1832-1847). The ready availability of automated external defibrillators (AEDs) has been advocated as a key component of this chain. Some authors have suggested a "fire extinguisher model" for AED deployment (Circulation 1998;98:2334-2351; Resuscitation 1995;30:151-156; Ann Intern Med 2001;135:990-998). In this model, AEDs are prominently displayed in public places for use by laypersons, much like fire extinguishers. For example, in Chicago's O'Hare Airport, AEDs are placed alongside fire extinguishers in the public concourse (N Engl J Med 2002;347:1242-1247). Advocates of this model suggest that advancing this practice would be a means to widely disbourse life-saving technology that is easy to use. Several experts have questioned this model, suggesting that the cost-effectiveness of distributing AEDs this widely would be prohibitive (BMJ 2002;325:515; Curr Opin Cardiol 2007;22:5-10; BMJ 2003;326:162; Int J Technol Assess Health Care 2007;23:362-367) and may not be more effective than more targeted distribution of AEDs. This literature review will examine the available data on both AEDs and fire extinguishers to determine if these comparisons are reasonable as a means of guiding public policy.

    2014-12-01

    The NASA Langley Research Center Science Directorate and Atmospheric Science Data Center have initiated a pilot program to utilize Geographic Information System (GIS) tools that enable, generate and store climatological averages using spatial queries and calculations in a spatial database resulting in greater accessibility of data for government agencies, industry and private sector individuals. The major objectives of this effort include the 1) Processing and reformulation of current data to be consistent with ESRI and openGIS tools, 2) Develop functions to improve capability and analysis that produce "on-the-fly" data products, extending these past the single location to regional and global scales. 3) Update the current web sites to enable both web-based and mobile application displays for optimization on mobile platforms, 4) Interact with user communities in government and industry to test formats and usage of optimization, and 5) develop a series of metrics that allow for monitoring of progressive performance. Significant project results will include the the development of Open Geospatial Consortium (OGC) compliant web services (WMS, WCS, WFS, WPS) that serve renewable energy and agricultural application products to users using GIS software and tools. Each data product and OGC service will be registered within ECHO, the Common Metadata Repository, the Geospatial Platform, and Data.gov to ensure the data are easily discoverable and provide data users with enhanced access to SSE data, parameters, services, and applications. This effort supports cross agency, cross organization, and interoperability of SSE data products and services by collaborating with DOI, NRCan, NREL, NCAR, and HOMER for requirements vetting and test bed users before making available to the wider public.

  8. Usage of data-encoded web maps with client side color rendering for combined data access, visualization, and modeling purposes

    2013-05-01

    Current approaches to satellite observation data storage and distribution implement separate visualization and data access methodologies which often leads to the need in time consuming data ordering and coding for applications requiring both visual representation as well as data handling and modeling capabilities. We describe an approach we implemented for a data-encoded web map service based on storing numerical data within server map tiles and subsequent client side data manipulation and map color rendering. The approach relies on storing data using the lossless compression Portable Network Graphics (PNG) image data format which is natively supported by web-browsers allowing on-the-fly browser rendering and modification of the map tiles. The method is easy to implement using existing software libraries and has the advantage of easy client side map color modifications, as well as spatial subsetting with physical parameter range filtering. This method is demonstrated for the ASTER-GDEM elevation model and selected MODIS data products and represents an alternative to the currently used storage and data access methods. One additional benefit includes providing multiple levels of averaging due to the need in generating map tiles at varying resolutions for various map magnification levels. We suggest that such merged data and mapping approach may be a viable alternative to existing static storage and data access methods for a wide array of combined simulation, data access and visualization purposes.

  9. Beyond the 'Networked Public Sphere': Politics, Participation and Technics in Web 2.0

    Directory of Open Access Journals (Sweden)

    Ben Roberts

    2009-01-01

    Full Text Available In some ways discussion of the political implications of Web 2.0 reinvigorates a debate about the democratising nature of the Internet that began in the 1990s. The concept of participation is at the heart of many current debates about politics and technology. There are two main reasons for saying this. On the one hand is an ongoing and increasing concern about public participation, or lack of it, in modern (predominantly Western democracies. This participatory deficit is to be seen in falling voter turnout at elections, public apathy on key political issues and scorn or indifference for elected political representatives. On the other hand, there is a wave of optimism concerning the potential of new technologies, particularly the web, to enable new forms of participation in economic and public life, to transform political debate and citizenship and to renew the ailing (or perceived to be ailing institutions of democracy. This optimism around participation and politics, while it has played a role in utopian visions of the internet more or less since its inception, has been reinvigorated recently by the discussion around the so-called Web 2.0. This article argues for a much more critical or sceptical approach to the political promise of Web 2.0. Focusing particularly on Yochai Benkler's The Wealth of Networks, it argues that current accounts of the participatory aspects of web culture tend to take a rather narrow view of what such participation might mean. However, aspects of the work of Bernard Stiegler, and that of others in the Ars Industrialis group co-founded by Stiegler, can help inform a more nuanced account of the relationship between politics and participation. It looks specifically at the arguments in Marc Crépon and Bernard Stiegler's book De la démocratie participative, written during the recent French presidential campaign, and will examine how the idea of participation articulates with key themes in Stiegler's philosophy of technics

    2015-03-01

    We explore how the analysis of web-based data, such as Twitter and Google Trends, can be used to assess the social relevance of an environmental accident. The concept and methods are applied in the shutdown of drinking water supply at the city of Toledo, Ohio, USA. Toledo's notice, which persisted from August 1 to 4, 2014, is a high-profile event that directly influenced approximately half a million people and received wide recognition. The notice was given when excessive levels of microcystin, a byproduct of cyanobacteria blooms, were discovered at the drinking water treatment plant on Lake Erie. Twitter mining results illustrated an instant response to the Toledo incident, the associated collective knowledge, and public perception. The results from Google Trends, on the other hand, revealed how the Toledo event raised public attention on the associated environmental issue, harmful algal blooms, in a long-term context. Thus, when jointly applied, Twitter and Google Trend analysis results offer complementary perspectives. Web content aggregated through mining approaches provides a social standpoint, such as public perception and interest, and offers context for establishing and evaluating environmental management policies.

    2009-09-01

    Full Text Available The concepts of publication, citation and dissemination of interactive keys and other online keys are discussed and illustrated by a sample paper published in the present issue (doi: 10.3897/zookeys.21.271. The present model is based on previous experience with several existing examples of publishing online keys. However, this model also suggests ways to publish, cite, preserve, disseminate and reuse the original data files to the benefit of the authors, future workers, and society in general. To be regarded as a ''formal scientific publication,'' an online key should satisfy the same criteria of peer review, registration, persistence, bibliographic description, etc., as conventional publications. Keys can be published in a form of either ''static'\\''dynamic'' publications. We define a ''static'' publication as a discrete unit of information preserved in a persistent and unchangeable way on the publisher’s Web site and/or on paper and consequently in conventional/electronic libraries and archives. This contrasts with the nature of the Internet, which allows and tends to encourage updating and improvement on a continuing basis. We call ''dynamic'' a publication of an interactive key on a Web site where its contents can be continuously updated. ''Dynamic'' publications meet some of the criteria of a ''formal scientific publication'' (identification, citation and location, while they lack other important features of it (persistence, archiving, indexing, science metric and citation metric services. Dynamic Web-based interactive keys may benefit from publishing the first version of their underlying datasets in a form of “formal scientific publication”. We define here the minimum set of data files to be published for several different platforms (Intkey, Lucid2, Lucid3, MX to ensure both (1 priority, identification, location and citation of the firstly published work and (2 future use and re-use of the keys.

    Full Text Available Public transit services (PTS improve mobility and accessibility, and reduce car dependence. It is ideal if PTS are financially sustainable, with affordable fares and expedient quality. The success of PTS on accessibility improvement can be reflected by their level of patronage: do travelers choose to use them in lieu of their private cars? PTS in Hong Kong are renowned for their quality and profitability, superbly addressing the accessibility need for the city; they carry over 90% of the 11 million daily trips. A comparison of the per capita train-car and bus-vehicle kilometer run of PTS in Hong Kong with those in London and Singapore, however, suggests that it is not purely the supply that affects the use or accessibility of PTS in Hong Kong. By tracing and analyzing the development of PTS in Hong Kong over the past two decades, we found evidence that the high level of accessibility on mass public transit in the territory can be attributed to the land use policy of developing compact, high-density township, accompanying transport policies of granting high priority to the development of mass transit facilities and providing ways to ensure the financial viability of privately operated PTS, especially the innovative approach of integrating the development of public transport facility and property so as to exploit their synergy. In this paper, we study and highlight elements that contribute to the development of high accessibility on mass public transit in Hong Kong.

    Bodzin, Alec Michael

    The purpose of this research has been to investigate the purposeful use of asynchronous telecommunications in a science education methods/curriculum course involving the use of a non-restrictive, public Web based forum for facilitating reflective discourse with preservice science teachers. Thirty-two preservice secondary school science teachers participated in a public science teaching forum on the World Wide Web during their student teaching internship. The forum was designed with NetForum software to be a place where science teachers share ideas, reflections and conversations on teaching and implementation of technology in the classroom and other instructional pedagogy, while also providing support for each other as members of an electronic professional community. A combination of quantitative and qualitative research methods were used to explore interaction patterns that facilitated collaborative preservice teacher reflective discourse on the forum and participants' attitudes towards using asynchronous telecommunications during their student teaching internship. Data from forum discourse analysis, interviews, and survey instruments illustrate that the use of this asynchronous Web-based forum provided the participants the opportunity to discuss and examine science concepts and reflect on classroom issues that were directly relevant to their student teaching experiences. The findings revealed that most participants had positive attitudes with respect to interacting with the Web-based forum. Furthermore, there were no significant differences in attitude between participants who had access to a networked computer and those who did not have access. An analysis of the forum postings showed that saturation in the discourse can occur with large groups participating in online asynchronous conversations.

    Abundant data on compound bioactivity and publicly accessible chemical databases increase opportunities for ligand-based drug discovery. In order to make full use of the data, an online platform for ligand-based virtual screening (LBVS) using publicly accessible databases has been developed. LBVS adopts Bayesian learning approach to create virtual screening models because of its noise tolerance, speed, and efficiency in extracting knowledge from data. LBVS currently includes data derived from BindingDB and ChEMBL. Three validation approaches have been employed to evaluate the virtual screening models created from LBVS. The tenfold cross validation results of twenty different LBVS models demonstrate that LBVS achieves an average AUC value of 0.86. Our internal and external testing results indicate that LBVS is predictive for lead identifications. LBVS can be publicly accessed at http://rcdd.sysu.edu.cn/lbvs.

  1. Location-allocation and accessibility models for improving the spatial planning of public health services.

    2015-01-01

    This study integrated accessibility and location-allocation models in geographic information systems as a proposed strategy to improve the spatial planning of public health services. To estimate the spatial accessibility, we modified the two-step floating catchment area (2SFCA) model with a different impedance function, a Gaussian weight for competition among service sites, a friction coefficient, distances along a street network based on the Dijkstra's algorithm and by performing a vectorial analysis. To check the accuracy of the strategy, we used the data from the public sterilization program for the dogs and cats of Bogot´a, Colombia. Since the proposed strategy is independent of the service, it could also be applied to any other public intervention when the capacity of the service is known. The results of the accessibility model were consistent with the sterilization program data, revealing that the western, central and northern zones are the most isolated areas under the sterilization program. Spatial accessibility improvement was sought by relocating the sterilization sites using the maximum coverage with finite demand and the p-median models. The relocation proposed by the maximum coverage model more effectively maximized the spatial accessibility to the sterilization service given the non-uniform distribution of the populations of dogs and cats throughout the city. The implementation of the proposed strategy would provide direct benefits by improving the effectiveness of different public health interventions and the use of financial and human resources.

    Archibong, Belinda

    While previous literature has emphasized the importance of energy and public infrastructure services for economic development, questions surrounding the implications of unequal spatial distribution in access to these resources remain, particularly in the developing country context. This dissertation provides evidence on the nature, origins and implications of this distribution uniting three strands of research from the development and political economy, regional science and energy economics fields. The dissertation unites three papers on the nature of spatial inequality of access to energy and infrastructure with further implications for conflict risk , the historical institutional and biogeographical determinants of current distribution of access to energy and public infrastructure services and the response of households to fuel price changes over time. Chapter 2 uses a novel survey dataset to provide evidence for spatial clustering of public infrastructure non-functionality at schools by geopolitical zone in Nigeria with further implications for armed conflict risk in the region. Chapter 3 investigates the drivers of the results in chapter 2, exploiting variation in the spatial distribution of precolonial institutions and geography in the region, to provide evidence for the long-term impacts of these factors on current heterogeneity of access to public services. Chapter 4 addresses the policy implications of energy access, providing the first multi-year evidence on firewood demand elasticities in India, using the spatial variation in prices for estimation.

    This exploratory study examines access to communication technologies, its association with health-related variables and study attrition, and its stability over time in a study of lower income African American women visiting urban public health centers. Participants (n = 1,227) provided information about cancer-related behaviors in a baseline questionnaire that also assessed their e-mail and cell phone/pager access. Interviews conducted at 1-, 6-, and 18-month follow up determined attrition, and an e-mail message sent to participants at 6-month follow up determined stability of access. Fewer than 10% of women reported e-mail access; 26% reported cell/phone pager access. At 6-month follow up, 45% of e-mail accounts were inactive; accounts from pay access providers were more likely to be inactive than work- or school-based accounts (58% versus 25%). Cell phone/pager access was positively associated with mammography knowledge. Attrition rates were lower among women with access than among those without access. Priorities for future research based on these preliminary findings are discussed.

    Access to technology in practice helps physicians manage information, communicate, and research topics; however, those in training receive almost no formal preparation for integrating web-based technologies into practice. One reason for this is that many faculty-aside from junior faculty or those in recent generations-did not grow up using Internet communication, may use it minimally, if at all, in their own practices, and may know little about its forms and varieties. This report presents a case to illustrate how these disparities may play out in the supervisory situation and makes suggestions about helping supervisors integrate technology-awareness into their teaching.

The Web first generation has instead been used by the administrators for dissemination and promotion.

    AutoHelp is a case-based, Web-accessible help desk for users of the EOSDIS. Its uses a combination of advanced computer and Web technologies, knowledge-based systems tools, and cognitive engineering to offload the current, person-intensive, help desk facilities at the DAACs. As a case-based system, AutoHelp starts with an organized database of previous help requests (questions and answers) indexed by a hierarchical category structure that facilitates recognition by persons seeking assistance. As an initial proof-of-concept demonstration, a month of email help requests to the Goddard DAAC were analyzed and partially organized into help request cases. These cases were then categorized to create a preliminary case indexing system, or category structure. This category structure allows potential users to identify or recognize categories of questions, responses, and sample cases similar to their needs. Year one of this research project focused on the development of a technology demonstration. User assistance 'cases' are stored in an Oracle database in a combination of tables linking prototypical questions with responses and detailed examples from the email help requests analyzed to date. When a potential user accesses the AutoHelp system, a Web server provides a Java applet that displays the category structure of the help case base organized by the needs of previous users. When the user identifies or requests a particular type of assistance, the applet uses Java database connectivity (JDBC) software to access the database and extract the relevant cases. The demonstration will include an on-line presentation of how AutoHelp is currently structured. We will show how a user might request assistance via the Web interface and how the AutoHelp case base provides assistance. The presentation will describe the DAAC data collection, case definition, and organization to date, as well as the AutoHelp architecture. It will conclude with the year 2 proposal to more fully develop the

    2009-04-01

    Full Text Available This research explored the awareness, usage and perspectives of Tanzanian researchers on open access as a mode of scholarly communication. A survey questionnaire targeted 544 respondents selected through stratified random sampling from a population of 1088 university researchers of the six public universities in Tanzania. With a response rate of 73%, the data were analysed using the Statistical Package for Social Sciences. The study reveals that the majority of the researchers were aware of and were positive towards open access. Findings further indicate that the majority of researchers in Tanzanian public universities used open access outlets more to access scholarly content than to disseminate their own research findings. It seems that most of these researchers would support open access publishing more if issues of recognition, quality and ownership were resolved. Thus many of them supported the idea of establishing institutional repositories at their respective universities as a way of improving the dissemination of local content. The study recommends that public universities and other research institutions in the country should consider establishing institutional repositories, with appropriate quality assurance measures, to improve the dissemination of research output emanating from these institutions.

  17. The purpose of peer review in the case of an open-access publication

    2006-09-01

    Full Text Available Abstract First scientific journals were simply a way of informing colleagues about new research findings. In due course, they started filtering out unreasonable claims, and introduced a peer-review system. The purpose of peer reviewing changed with time. Since the middle of the past century, commercial publishers have owned a large number of scientific journals and as a result, the marketable value of a submitted manuscript has become an increasingly important factor in publishing decisions. Recently some publishers have developed business schemes which may stop this tendency. In the case of an open-access publication, the marketable value of a manuscript is not the primary consideration, since access to the research is not being sold. This innovation challenges scientists to re-consider the purpose of peer review. This editorial indicates some of the commonly used criteria for publication that consequently should receive less or little emphasis under the open-access model.

  18. Cooperation and contagion in web-based, networked public goods experiments.

    Science.gov (United States)

    Suri, Siddharth; Watts, Duncan J

    2011-03-11

    A longstanding idea in the literature on human cooperation is that cooperation should be reinforced when conditional cooperators are more likely to interact. In the context of social networks, this idea implies that cooperation should fare better in highly clustered networks such as cliques than in networks with low clustering such as random networks. To test this hypothesis, we conducted a series of web-based experiments, in which 24 individuals played a local public goods game arranged on one of five network topologies that varied between disconnected cliques and a random regular graph. In contrast with previous theoretical work, we found that network topology had no significant effect on average contributions. This result implies either that individuals are not conditional cooperators, or else that cooperation does not benefit from positive reinforcement between connected neighbors. We then tested both of these possibilities in two subsequent series of experiments in which artificial seed players were introduced, making either full or zero contributions. First, we found that although players did generally behave like conditional cooperators, they were as likely to decrease their contributions in response to low contributing neighbors as they were to increase their contributions in response to high contributing neighbors. Second, we found that positive effects of cooperation were contagious only to direct neighbors in the network. In total we report on 113 human subjects experiments, highlighting the speed, flexibility, and cost-effectiveness of web-based experiments over those conducted in physical labs.

    2013-02-01

    Full Text Available Background: Web of Science (WoS is an online academic citation index provided by Thomson Reuters which supplies valuable bibliometric information for comparing impact of specific author, organization, or country in science production. The aim of this study was to compare toxicology publications of Iran and Turkey indexed in WoS from bibliometric point of view. Methods: The WoS database was queried based on keywords “Iran” and “Turkey” separately in the “Address” field and refined by “Toxicology” as a category. All records were transferred to Microsoft Excel® application. The dataset were analyzed from different perspectives, such as publication years, number of references and citations, authorship pattern, publications types, affiliated organizations, core subject areas and journals. Results: There were 1178 and 2240 publications that met the criteria during 1993-2011 for Iran and Turkey, respectively. Less than 2% of authors had published more than 25% of all toxicology papers in both countries. The average number of citation per article was about 3.48 for Iranian and 6.73 for Turkish papers. By the time of the analysis, 54.3% of Iranian and 31.6% of Turkish articles had not received any citation. Conclusion: This analysis reveals that top Iranian toxicologists had a better performance than their Turkish counterparts but overall authorship pattern was well-distributed among Turkish researchers and organizations. If Iranian authors desire to achieve first rank of toxicology articles in the Middle East region by 2025, they must try to increase the quantity and quality of their international publications.

    2002-01-01

    For more than 10 years the National Cancer Institute (NCI) has tested compounds for their ability to inhibit the growth of human tumor cell lines in culture (NCI screen). Work of Ken Paull [J. Natl. Cancer Inst. 81 (1989) 1088] demonstrated that compounds with similar mechanism of cell growth inhibition show similar patterns of activity in the NCI screen. This observation was developed into an algorithm called COMPARE and has been successfully used to predict mechanisms for a wide variety of compounds. More recently, this method has been extended to associate patterns of cell growth inhibition by compounds with measurements of molecular entities (such as gene expression) in the cell lines in the NCI screen. The COMPARE method and associated data are freely available on the Developmental Therapeutics Program (DTP) web site (http://dtp.nci.nih.gov/). Examples of the use of COMPARE on these web pages will be explained and demonstrated. Published by Elsevier Science Inc.

    Prendiville, T W

    2012-02-01

    OBJECTIVES: To establish the information-seeking behaviours of paediatricians in answering every-day clinical queries. DESIGN: A questionnaire was distributed to every hospital-based paediatrician (paediatric registrar and consultant) working in Ireland. RESULTS: The study received 156 completed questionnaires, a 66.1% response. 67% of paediatricians utilised the internet as their first "port of call" when looking to answer a medical question. 85% believe that web-based resources have improved medical practice, with 88% reporting web-based resources are essential for medical practice today. 93.5% of paediatricians believe attempting to answer clinical questions as they arise is an important component in practising evidence-based medicine. 54% of all paediatricians have recommended websites to parents or patients. 75.5% of paediatricians report finding it difficult to keep up-to-date with new information relevant to their practice. CONCLUSIONS: Web-based paediatric resources are of increasing significance in day-to-day clinical practice. Many paediatricians now believe that the quality of patient care depends on it. Information technology resources play a key role in helping physicians to deliver, in a time-efficient manner, solutions to clinical queries at the point of care.

    2011-09-01

    Interactive mapping and spatial analysis tools are under-utilized by health researchers and decision-makers as a result of scarce training materials, few examples demonstrating the successful use of geographic visualization, and poor mechanisms for sharing results generated by geovisualization. Here, we report on the development of the Geovisual EXplication(G-EX) Portal, a web-based application designed to connect researchers in geovisualization and related mapping sciences, to users who are working in public health and epidemiology. This paper focuses on the design and development of the G-EX Portal Learn module, a set of tools intended to disseminate learning artifacts. Initial design and development of the G-EX Portal has been guided by our past research on the use and usability of geovisualization in public health. As part of the iterative design and development process, we conducted a needs assessment survey with targeted end-users, which we report on here. The survey focused on users' current learning habits, their preferred kind of learning artifacts and issues they may have with contributing learning artifacts to web portals. Survey results showed that users desire a diverse set of learning artifacts in terms of both formats and topics covered. Results also revealed a willingness of users to contribute both learning artifacts and personal information that would help other users to evaluate the credibility of the learning artifact source. We include a detailed description of the G-EX Portal Learn module and focus on modifications to the design of the Learn module as a result from feedback we received from our survey.

  5. Use of Web 2.0 Technologies for Public Outreach on a Simulated Mars Mission

    2009-12-01

    Recent advances in social media and internet communications have revolutionized the ways people interact and disseminate information. Astronauts are already starting to take advantage of these tools by blogging and tweeting from space, and almost all NASA missions now have presences on the major social networking sites. One priority for future human explorers on Mars will be communicating their experiences to the people back on Earth. During July 2009, a six-member crew of volunteers carried out a simulated Mars mission at the Flashline Mars Arctic Research Station (FMARS) on Devon Island in the Canadian Arctic. Living in a habitat, conducting EVAs wearing spacesuits, and observing communication delays with “Earth,” the crew endured restrictions similar to those that will be faced by future human Mars explorers. Throughout the expedition, crewmembers posted regular blog entries, reports, photos, videos, and updates to their website and social media outlets Twitter, Facebook, YouTube, and Picasa Web Albums. During the sixteen EVAs of their field science research campaign, FMARS crewmembers collected GPS track information and took geotagged photos using GPS-enabled cameras. They combined their traverse GPS tracks with photo location information into KML/KMZ files that website visitors can view in Google Maps or Google Earth. Although the crew observed a strict 20-minute communication delay with “Earth” to simulate a real Mars mission, they broke this rule to conduct four very successful live webcasts with student groups using Skype since education and public outreach were important objectives of the endeavor. This presentation will highlight the use of Web 2.0 technologies for public outreach during the simulated Mars expedition and the implications for other remote scientific journeys. The author embarks on a "rover" to carry out an EVA near the FMARS Habitat. The satellite dish to the right of the structure was used for all communications with the remote

  7. Open Access Data Centers as an Essential Partner to a Data Publication Journal

    2016-12-01

    The success of Earth System Science Data derives in part from key infrastructure: digital object identifiers (doi) and open access data centers. Our concept that a data journal should promote access and exchange through publication of reviewed data descriptions presupposed third parties to hold the data. As minimum criteria for those data centers we expected international reputation for quality of service and an active lifetime extending at least a decade into the future. We also expected modern access interfaces offering geographic, topical and parameter-based browsing - so that users could discover related holdings through an ESSD link or discover ESSD by way of links in data sets revealed through the center's browse tools - and true open access. True open access means one or two clicks from abstract in ESSD to the data itself without barriers. We started with Pangaea and CDIAC. Data providers already used these centers, the staff welcomed the ESSD initiative and all parties cooperated on doi. With this initial support ESSD proved the basic concept of data publication and demonstrated utility to a larger group of data providers, many of whom suggested additional centers. So long as those data centers met expectations for open access and quality and durability of service, ESSD agreed to collaborate. Through back-door collaborations - e.g. service on particular data sets - ESSD developed working partnerships with more than 30 data centers in 13 countries. Data centers ask to join our list. We encourage those centers to stimulate local providers to submit a data set to ESSD, thus preserving our practical data-set by data-set partnership mode. For a few data centers where national policies impose a registration step, center staff and ESSD editors created bypass access routes to facilitate anonymous reviews. For ESSD purposes, open access and doi cooperation leading to reliable curation allows a win, win, win partnership among centers, providers, and journal.

    Electronic discovery of the clinical trials being performed at a specific research center is a challenging task, which presently requires manual review of the center's locally maintained databases or web pages of protocol listings. Near real-time automated discovery of available trials would increase the efficiency and effectiveness of clinical trial searching, and would facilitate the development of new services for information providers and consumers. Automated discovery efforts to date have been hindered by issues such as disparate database schemas, vocabularies, and insufficient standards for easy intersystem exchange of high-level data, but adequate infrastructure now exists that make possible the development of applications for near real-time automated discovery of trials. This paper describes the current state (design and implementation) of the Web Services Specification for Publication and Discovery of Clinical Trials as developed by the Technology Task Force of the Association of American Cancer Institutes. The paper then briefly discusses a prototype web service-based application that implements the specification. Directions for evolution of this specification are also discussed.

    McGlynn, T. A.; White, N. E.; Fernique, P.; Wenger, M.; Ochsenbein, F.

    1997-12-01

    We have developed Astrobrowse, a Web search engine where a user may submit a target or position query and have the system search hundreds of possible sites for matching information. Astrobrowse has been developed at NASA's High Energy Astronomy Science Archive Research Center, and uses the GLU syntax and protocols developed at the Centre de Donnees Astronomiques de Strasbourg. Astrobrowse takes the information supplied by a user and then using a GLU database (see Fernique, et al., this conference) generates a query appropriate for each of the resources the user is interested in. Astrobrowse is available at the URL: http://heasarc.gsfc.nasa.gov/ab. Astrobrowse acts essentially as a user agent. Although the user may have requested information from sites around the world, results are cached locally so that the user can quickly move among the various responses. Users can initially select sites based upon matches to text searches (a la Altavista and other Web search engines) or by searching a hierarchical tree of resources. GLU helps Astrobrowse to maintain up-to-date pointers to all sites and allows easy distribution of this list to any other site which might wish to bring up their own Astrobrowse agent. GLU also provides facilities which allow Astrobrowse to access the most responsive resource in cases where a resource is mirrored at multiple sites. All software used within our Astrobrowse installation is freely available for any purpose and we encourage other groups to develop their own customized agents. Links to information and software are available at the Astrobrowse home page. There is also a form available to suggest new pages to be added to the HEASARC Astrobrowse agent. Astrobrowse can be used independently of GLU, in which case updating of the site list must be done completely manually. Please send comments or suggestions for Astrobrowse to tam@silk.gsfc.nasa.gov.

  11. Intellectual property rights vs. public access rights: ethical aspects of the DeCSS decryptation program

    Directory of Open Access Journals (Sweden)

    Robert Vaagan

    2005-01-01

    Full Text Available Introduction. In 1999-2000, a Norwegian youth cracked a DVD-access code and published a decryptation program on the Internet. He was sued by the US DVD Copy Control Association (DVD-CCA and the Norwegian Motion Picture Association (MAP, allies of the US Motion Picture Association of America (MPAA, arrested by Norwegian police and charged with data crime. Two Norwegian court rulings in 2003 unanimously ruled that the program did not amount to a breach of Norwegian law, and he was fully acquitted. In the US, there have been related cases, some with other outcomes. Method. Based on a theoretical framework developed by Zwass, the paper discusses these court rulings and the wider issues of intellectual property rights versus public access rights. Analysis. The DVD-Jon case illustrates that intellectual property rights can conflict with public access rights, as the struggle between proprietary software and public domain software, as well as the SPARC and Open Archives Initiative reflect. Results. An assessment of the DVD-Jon case based on the Zwass framework does not give a clear information ethics answer. The analysis depends on whether one ascribes to consequentialist (e.g., utilitarian or de-ontological reflection, and also on which side of the digital gap is to be accorded most weight. Conclusion. While copyright interests are being legally strengthened, there may be ethically- grounded access rights that outweigh property rights.

  12. Open access of evidence-based publications: the case of the orthopedic and musculoskeletal literature.

    2015-11-01

    The open access model, where researchers can publish their work and make it freely available to the whole medical community, is gaining ground over the traditional type of publication. However, fees are to be paid by either the authors or their institutions. The purpose of this paper is to assess the proportion and type of open access evidence-based articles in the form of systematic reviews and meta-analyses in the field of musculoskeletal disorders and orthopedic surgery. PubMed database was searched and the results showed a maximal number of hits for low back pain and total hip arthroplasty. We demonstrated that despite a 10-fold increase in the number of evidence-based publications in the past 10 years, the rate of free systematic reviews in the general biomedical literature did not change for the last two decades. In addition, the average percentage of free open access systematic reviews and meta-analyses for the commonest painful musculoskeletal conditions and orthopedic procedures was 20% and 18%, respectively. Those results were significantly lower than those of the systematic reviews and meta-analyses in the remaining biomedical research. Such findings could indicate a divergence between the efforts engaged at promoting evidence-based principles and those at disseminating evidence-based findings in the field of musculoskeletal disease and trauma. The high processing fee is thought to be a major limitation when considering open access model for publication.

    Full Text Available EXTENDED ABSTRACTFor the first time, the Dolenjska museum Novo mesto provided access to digitised museum resources when they took the decision to enrich the exhibition Novo mesto 1848-1918 by adding digital content. The following goals were identified: the digital content was created at the time of exhibition planning and design, it met the needs of different age groups of visitors, and during the exhibition the content was accessible via touch screen. As such, it also served for educational purposes (content-oriented lectures or problem solving team work. In the course of exhibition digital content was accessible on the museum website http://www.novomesto1848-1918.si. The digital content was divided into the following sections: the web photo gallery, the quiz and the game. The photo gallery was designed in the same way as the exhibition and the print catalogue and extended by the photos of contemporary Novo mesto and accompanied by the music from the orchestron machine. The following themes were outlined: the Austrian Empire, the Krka and Novo mesto, the town and its symbols, images of the town and people, administration and economy, social life and Novo mesto today followed by digitised archive materials and sources from that period such as the Commemorative book of the Uniformed Town Guard, the National Reading Room Guest Book, the Kazina guest book, the album of postcards and the Diploma of Honoured Citizen Josip Gerdešič. The Web application was also a tool for a simple and on line selection of digitised material and the creation of new digital content which proved to be much more convenient for lecturing than Power Point presentations. The quiz consisted of 40 questions relating to the exhibition theme and the catalogue. Each question offered a set of three answers only one of them being correct and illustrated by photography. The application auto selected ten questions and valued the answers immediately. The quiz could be accessed

    2005-01-01

    In this paper we present the results of the StatSearch case study that aimed at providing an enhanced access to statistical data available on the Web. In the scope of this case study we developed a prototype of an information access tool combining a query-based search engine with semi-automated navigation techniques exploiting the hierarchical structuring of the available data. This tool enables a better control of the information retrieval, improving the quality and ease of the access to statistical information. The central part of the presented StatSearch tool consists in the design of an algorithm for automated navigation through a tree-like hierarchical document structure. The algorithm relies on the computation of query related relevance score distributions over the available database to identify the most relevant clusters in the data structure. These most relevant clusters are then proposed to the user for navigation, or, alternatively, are the support for the automated navigation process. Several appro...

    The development of public transit systems that are accessible and safe for everyone, including people with special needs, is an objective that is justified from the civic and economic points of view. Unfortunately, public transit services are conceived for people who do not have reduced physical or cognitive abilities. In this paper, we present an intelligent public transit system by highway with the goal of facilitating access and improving the safety of public transit for persons with special needs. The system is deployed using components that are commonly available in transport infrastructure, e.g., sensors, mobile communications systems, and positioning systems. In addition, the system can operate in non-urban transport contexts, e.g., isolated rural areas, where the availability of basic infrastructure, such as electricity and communications infrastructures, is not always guaranteed. To construct the system, the principles and techniques of Ubiquitous Computing and Ambient Intelligence have been employed. To illustrate the utility of the system, two cases of services rendered by the system are described: the first case involves a surveillance system to guarantee accessibility at bus stops; the second case involves a route assistant for blind people.

    Clements, Oliver; Walker, Peter

    2017-04-01

    The ESA Ocean Colour - Climate Change Initiative (ESA OC-CCI) has produced a long-term high quality global dataset with associated per-pixel uncertainty data. This dataset has now grown to several hundred terabytes (uncompressed) and is freely available to download. However, the sheer size of the dataset can act as a barrier to many users; large network bandwidth, local storage and processing requirements can prevent researchers without the backing of a large organisation from taking advantage of this raw data. The EC H2020 project, EarthServer2, aims to create a federated data service providing access to more than 1 petabyte of earth science data. Within this federation the Marine Data Service already provides an innovative on-line tool-kit for filtering, analysing and visualising OC-CCI data. Data are made available, filtered and processed at source through a standards-based interface, the Open Geospatial Consortium Web Coverage Service and Web Coverage Processing Service. This work was initiated in the EC FP7 EarthServer project where it was found that the unfamiliarity and complexity of these interfaces itself created a barrier to wider uptake. The continuation project, EarthServer2, addresses these issues by providing higher level tools for working with these data. We will present some examples of these tools. Many researchers wish to extract time series data from discrete points of interest. We will present a web based interface, based on NASA/ESA WebWorldWind, for selecting points of interest and plotting time series from a chosen dataset. In addition, a CSV file of locations and times, such as a ship's track, can be uploaded and these points extracted and returned in a CSV file allowing researchers to work with the extract locally, such as a spreadsheet. We will also present a set of Python and JavaScript APIs that have been created to complement and extend the web based GUI. These APIs allow the selection of single points and areas for extraction.

    The National Center for Biomedical Ontology (NCBO) is one of the National Centers for Biomedical Computing funded under the NIH Roadmap Initiative. Contributing to the national computing infrastructure, NCBO has developed BioPortal, a web portal that provides access to a library of biomedical ontologies and terminologies (http://bioportal.bioontology.org) via the NCBO Web services. BioPortal enables community participation in the evaluation and evolution of ontology content by providing features to add mappings between terms, to add comments linked to specific ontology terms and to provide ontology reviews. The NCBO Web services (http://www.bioontology.org/wiki/index.php/NCBO_REST_services) enable this functionality and provide a uniform mechanism to access ontologies from a variety of knowledge representation formats, such as Web Ontology Language (OWL) and Open Biological and Biomedical Ontologies (OBO) format. The Web services provide multi-layered access to the ontology content, from getting all terms in an ontology to retrieving metadata about a term. Users can easily incorporate the NCBO Web services into software applications to generate semantically aware applications and to facilitate structured data collection.

  8. Web-based access to teaching files in a filmless radiology environment

    Science.gov (United States)

    Rubin, Richard K.; Henri, Christopher J.; Cox, Robert D.; Bret, Patrice M.

    1998-07-01

    This paper describes the incorporation of radiology teaching files within our existing filmless radiology Picture Archiving and Communications System (PACS). The creation of teaching files employs an intuitive World Wide Web (WWW) application that relieves the creator of the technical details involving the underlying PACS and obviates the need for knowledge of Internet publishing. Currently, our PACS supports filmless operation of CT, MRI, and ultrasound modalities, conforming to the Digital Imaging and Communications in Medicine (DICOM) and Health Level 7 (HL7) standards. Web-based teaching files are one module in a suite of WWW tools, developed in-house, for platform independent management of radiology data. The WWW browser tools act as liaison between inexpensive desktop PCs and the DICOM PACS. The creation of a teaching file is made as efficient as possible by allowing the creator to select the images and prepare the text within a single application, while finding and reviewing existing teaching files is simplified with a flexible, multi-criteria searching tool. This efficient and easy-to-use interface is largely responsible for the development of a database, currently containing over 400 teaching files, that has been generated in a short period of time.

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

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

    2013-12-01

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

  15. A typology of intellectual property management for public health innovation and access: design considerations for policymakers.

    Science.gov (United States)

    Taubman, Antony

    2010-01-19

    This paper seeks to set the practical discipline of public interest intellectual property (IP) management in public health into its broader policy context. The most immediate and direct impact of IP systems on public welfare results not from international standards nor from national legislation - though these norms are fundamentally important - but rather from the accumulated impact of numerous practical choices whether or not to seek IP protection; where and where not; and how any exclusive rights are deployed, by whom, and to what end. IP management is the essentially practical exercise of limited exclusive rights over protected subject matter, the judicious use of those rights to leverage outcomes that advance an institution's or a firm's objectives. Exclusive rights are used to construct and define knowledge-based relationships, to leverage access to technology and other necessary resources, and to enhance market-based incentives. IP management choices range across a broad spectrum, spanning public domain strategies, open or exclusive licensing, and strong exclusivity. The idea of 'exclusive rights', as a specific legal mechanism, can run counter to expectations of greater openness and accessibility, but actual outcomes will depend very much on how these mechanisms are used in practice. For public interest or public sector institutions concerned with health research and development, particularly the development of new medicines, IP management choices can be just as critical as they are for private firms, although a predominant institutional concentration on advancing direct public interest objectives may lead to significantly different approaches in weighing and exercising practical choices for IP management: even so, a private sector approach should not be conflated with exclusivity as an end in itself, nor need public interest IP management eschew all leverage over IP. This paper offers a tentative framework for a richer typology of those choices, to give a

    2008-09-24

    The Hanford Borehole Geologic Information System (HBGIS) is a prototype web-based graphical user interface (GUI) for viewing and downloading borehole geologic data. The HBGIS is being developed as part of the Remediation Decision Support function of the Soil and Groundwater Remediation Project, managed by Fluor Hanford, Inc., Richland, Washington. Recent efforts have focused on improving the functionality of the HBGIS website in order to allow more efficient access and exportation of available data in HBGIS. Users will benefit from enhancements such as a dynamic browsing, user-driven forms, and multi-select options for selecting borehole geologic data for export. The need for translating borehole geologic data into electronic form within the HBGIS continues to increase, and efforts to populate the database continue at an increasing rate. These new web-based tools should help the end user quickly visualize what data are available in HBGIS, select from among these data, and download the borehole geologic data into a consistent and reproducible tabular form. This revised user’s guide supersedes the previous user’s guide (PNNL-15362) for viewing and downloading data from HBGIS. It contains an updated data dictionary for tables and fields containing borehole geologic data as well as instructions for viewing and downloading borehole geologic data.

  17. Kinome Render: a stand-alone and web-accessible tool to annotate the human protein kinome tree.

    Science.gov (United States)

    Chartier, Matthieu; Chénard, Thierry; Barker, Jonathan; Najmanovich, Rafael

    2013-01-01

    Human protein kinases play fundamental roles mediating the majority of signal transduction pathways in eukaryotic cells as well as a multitude of other processes involved in metabolism, cell-cycle regulation, cellular shape, motility, differentiation and apoptosis. The human protein kinome contains 518 members. Most studies that focus on the human kinome require, at some point, the visualization of large amounts of data. The visualization of such data within the framework of a phylogenetic tree may help identify key relationships between different protein kinases in view of their evolutionary distance and the information used to annotate the kinome tree. For example, studies that focus on the promiscuity of kinase inhibitors can benefit from the annotations to depict binding affinities across kinase groups. Images involving the mapping of information into the kinome tree are common. However, producing such figures manually can be a long arduous process prone to errors. To circumvent this issue, we have developed a web-based tool called Kinome Render (KR) that produces customized annotations on the human kinome tree. KR allows the creation and automatic overlay of customizable text or shape-based annotations of different sizes and colors on the human kinome tree. The web interface can be accessed at: http://bcb.med.usherbrooke.ca/kinomerender. A stand-alone version is also available and can be run locally.

    "Water is everywhere." This sentiment underscores the importance of instilling hydrologic and earth science literacy in educators, students, and the general public, but also presents challenges for water scientists and educators. Scientific data about water is collected and distributed by several different sources, from federal agencies to scientific investigators to citizen scientists. As competition for limited water resources increase, increasing access to and understanding of the wealth of information about the nation's and the world's water will be critical. The CUAHSI-HIS system is a web based system for sharing hydrologic data that can help address this need. HydroDesktop is a free, open source application for finding, getting, analyzing and using hydrologic data from the CUAHSI-HIS system. It works with HydroCatalog which indexes the data to find out what data exists and where it is, and then it retrieves the data from HydroServers where it is stored communicating using WaterOneFlow web services. Currently, there are over 65 services registered in HydroCatalog providing central discovery of water data from several federal and state agencies, university projects, and other sources. HydroDesktop provides a simplified GIS that allows users to incorporate spatial data, and simple analysis tools to facilitate graphing and visualization. HydroDesktop is designed to be useful for a number of different groups of users with a wide variety of needs and skill levels including university faculty, graduate and undergraduate students, K-12 students, engineering and scientific consultants, and others. This presentation will highlight some of the features of HydroDesktop and the CUAHSI-HIS system that make it particularly appropriate for use in educational and public outreach settings, and will present examples of educational use. The incorporation of "real data," localization to an area of interest, and problem-based learning are all recognized as effective strategies for

    Full Text Available Abstract Background Geographic Information Systems (GIS are powerful communication tools for public health. However, using GIS requires considerable skill and, for this reason, is sometimes limited to experts. Web-based GIS has emerged as a solution to allow a wider audience to have access to geospatial information. Unfortunately the cost of implementing proprietary solutions may be a limiting factor in the adoption of a public health GIS in a resource-constrained environment. Scalable Vector Graphics (SVG is used to define vector-based graphics for the internet using XML (eXtensible Markup Language; it is an open, platform-independent standard maintained by the World Wide Web Consortium (W3C since 2003. In this paper, we summarize our methodology and demonstrate the potential of this free and open standard to contribute to the dissemination of Expanded Program on Immunization (EPI information by providing interactive maps to a wider audience through the Internet. Results We used SVG to develop a database driven web-based GIS applied to EPI data from three countries of WHO AFRO (World Health Organization – African Region. The system generates interactive district-level country immunization coverage maps and graphs. The approach we describe can be expanded to cover other public health GIS demanding activities, including the design of disease atlases in a resources-constrained environment. Conclusion Our system contributes to accumulating evidence demonstrating the potential of SVG technology to develop web-based public health GIS in resources-constrained settings.

    2011-11-01

    Full Text Available General search engines often provide low precise results even for detailed queries. So there is a vital needto elicit useful information like keywords for search engines to provide acceptable results for user’s searchqueries. Although many methods have been proposed to show how to extract keywords automatically, allattempt to get a better recall, precision and other criteria which describe how the method has done its jobas an author. This paper presents a new automatic keyword extraction method which improves accessibilityof web content by search engines. The proposed method defines some coefficients determining featuresefficiency and tries to optimize them by using a genetic algorithm. Furthermore, it evaluates candidatekeywords by a function that utilizes the result of search engines. When comparing to the other methods,experiments demonstrate that by using the proposed method, a higher score is achieved from searchengines without losing noticeable recall or precision.

    2013-12-01

    The purpose of this article is to review the steps that can be taken to ensure secure transfer of information over public and home networks, given the increasing utilization of mobile devices in radiology. With the rapid technologic developments in radiology, knowledge of various technical aspects is crucial for any practicing radiologist. Utilization of mobile devices, such as laptops, tablets, and even cellular phones, for reading radiologic studies has become increasingly prevalent. With such usage comes a need to ensure that both the user's and the patient's private information is protected. There are several steps that can be taken to protect sensitive information while using public networks. These steps include being diligent in reviewing the networks to which one connects, ensuring encrypted connections to web-sites, using strong passwords, and using a virtual private network and a firewall. As the role of information technology in modern radiology practice becomes more critical, these safety mechanisms must be addressed when viewing studies on any mobile device.

  5. Genomics and Public Health Research: Can the State Allow Access to Genomic Databases?

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available Because many diseases are multifactorial disorders,the scientific progress in genomics and genetics should be taken into consideration in public health research. In this context, genomic databases will constitute an important source of information. Consequently, it is important to identify and characterize the State's role and authority on matters related to public health,in order to verify whether it has access to such databases while engaging in public health genomic research. We first consider the evolution of the concept of public health, as well as its core functions, using a comparative approach (e.g. WHO, PAHO, CDC and the Canadian province of Quebec. Following an analysis of relevant Quebec legislation, the precautionary principle is examined as a possible avenue to justify State access to and use of genomic databases for research purposes. Finally, we consider the Influenza pandemic plans developed by WHO, Canada, and Quebec,as examples of key tools framing public health decision-making process.We observed that State powers in public health, are not,in Quebec,well adapted to the expansion of genomics research.We propose that the scope of the concept of research in public health should be clear and include the following characteristics:a commitment to the health and well-being of the population and to their determinants; the inclusion of both applied research and basic research; and, an appropriate model of governance (authorization, follow-up,consent, etc..We also suggest that the strategic approach version of the precautionary principle could guide collective choices in these matters.

    Cancer risk prediction tools provide valuable information to clinicians but remain computationally challenging. Many clinics find that CaGene or HughesRiskApps fit their needs for easy- and ready-to-use software to obtain cancer risks; however, these resources may not fit all clinics' needs. The HughesRiskApps Group and BayesMendel Lab therefore developed a web service, called "Risk Service", which may be integrated into any client software to quickly obtain standardized and up-to-date risk predictions for BayesMendel tools (BRCAPRO, MMRpro, PancPRO, and MelaPRO), the Tyrer-Cuzick IBIS Breast Cancer Risk Evaluation Tool, and the Colorectal Cancer Risk Assessment Tool. Software clients that can convert their local structured data into the HL7 XML-formatted family and clinical patient history (Pedigree model) may integrate with the Risk Service. The Risk Service uses Apache Tomcat and Apache Axis2 technologies to provide an all Java web service. The software client sends HL7 XML information containing anonymized family and clinical history to a Dana-Farber Cancer Institute (DFCI) server, where it is parsed, interpreted, and processed by multiple risk tools. The Risk Service then formats the results into an HL7 style message and returns the risk predictions to the originating software client. Upon consent, users may allow DFCI to maintain the data for future research. The Risk Service implementation is exemplified through HughesRiskApps. The Risk Service broadens the availability of valuable, up-to-date cancer risk tools and allows clinics and researchers to integrate risk prediction tools into their own software interface designed for their needs. Each software package can collect risk data using its own interface, and display the results using its own interface, while using a central, up-to-date risk calculator. This allows users to choose from multiple interfaces while always getting the latest risk calculations. Consenting users contribute their data for future

    Current methods of searching for and retrieving data from satellite land remote sensing archives do not allow for interactive information extraction. Instead, Earth science data users are required to download files over low-bandwidth networks to local workstations and process data before science questions can be addressed. New methods of extracting information from data archives need to become more interactive to meet user demands for deriving increasingly complex information from rapidly expanding archives. Moving the tools required for processing data to computer systems of data providers, and away from systems of the data consumer, can improve turnaround times for data processing workflows. The implementation of middleware services was used to provide interactive access to archive data. The goal of this middleware services development is to enable Earth science data users to access remote sensing archives for immediate answers to science questions instead of links to large volumes of data to download and process. Exposing data and metadata to web-based services enables machine-driven queries and data interaction. Also, product quality information can be integrated to enable additional filtering and sub-setting. Only the reduced content required to complete an analysis is then transferred to the user.

    Thousands of (Quantitative) Structure-Activity Relationships (Q)SAR models have been described in peer-reviewed publications; however, this way of sharing seldom makes models available for the use by the research community outside of the developer's laboratory. Conversely, on-line models allow broad dissemination and application representing the most effective way of sharing the scientific knowledge. Approaches for sharing and providing on-line access to models range from web services created by individual users and laboratories to integrated modeling environments and model repositories. This emerging transition from the descriptive and informative, but "static", and for the most part, non-executable print format to interactive, transparent and functional delivery of "living" models is expected to have a transformative effect on modern experimental research in areas of scientific and regulatory use of (Q)SAR models. © 2017 Wiley-VCH Verlag GmbH & Co.

    Recent advances in social media and internet communications have revolutionized the ways people interact and disseminate information. Astronauts are already taking advantage of these tools by blogging and tweeting from space, and almost all NASA missions now have presences on the major social networking sites. One priotity for future human explorers on Mars will be communicating their experiences to the people back on Earth. During July 2009, a 6-member crew of volunteers carried out a simulated Mars mission at the Flashline Mars Arctic Research Station (FMARS). The Mars Society built the mock Mars habitat in 2000-01 to help develop key knowledge and inspire the public for human Mars exploration. It is located on Devon island about 1600 km from the North Pole within the Arctic Circle. The structure is situated on the rim of Haughton Crater in an environment geologically and biologically analogous to Mars. Living in a habitat, conducting EVAs wearing spacesuits, and observing communication delays with "Earth,"the crew endured restrictions similar to those that will be faced by future human Mars explorers. Throughout the expedition, crewmembers posted daily blog entries, reports, photos, videos, and updates to their website and social media outlets Twitter, Facebook, YouTube, and Picasa Web Albums. During the sixteen EVAs of thier field science research campaign, FMARS crewmembers collected GPS track information and took geotagged photos using GPS-enabled cameras. They combined their traverse GPS tracks with photo location information into KML/KMZ files that website visitors can view in Google Earth.

  17. Beyond information access: Support for complex cognitive activities in public health informatics tools.

    Science.gov (United States)

    Sedig, Kamran; Parsons, Paul; Dittmer, Mark; Ola, Oluwakemi

    2012-01-01

    Public health professionals work with a variety of information sources to carry out their everyday activities. In recent years, interactive computational tools have become deeply embedded in such activities. Unlike the early days of computational tool use, the potential of tools nowadays is not limited to simply providing access to information; rather, they can act as powerful mediators of human-information discourse, enabling rich interaction with public health information. If public health informatics tools are designed and used properly, they can facilitate, enhance, and support the performance of complex cognitive activities that are essential to public health informatics, such as problem solving, forecasting, sense-making, and planning. However, the effective design and evaluation of public health informatics tools requires an understanding of the cognitive and perceptual issues pertaining to how humans work and think with information to perform such activities. This paper draws on research that has examined some of the relevant issues, including interaction design, complex cognition, and visual representations, to offer some human-centered design and evaluation considerations for public health informatics tools.

    Purpose - The purpose of this paper is to introduce the special issue on improving equitable access to health care through increased public and patient involvement (PPI) in prioritization decisions by discussing the conceptualization, scope and rationales of PPI in priority setting that inform the special issue. Design/methodology/approach - The paper employs a mixed-methods approach in that it provides a literature review and a conceptual discussion of the common themes emerging in the field of PPI and health priority setting. Findings - The special issue focuses on public participation that is collective in character, in the sense that the participation relates to a social, not personal, decision and is relevant to whole groups of people and not single individuals. It is aimed at influencing a decision on public policy or legal rules. The rationales for public participation can be found in democratic theory, especially as they relate to the social and political values of legitimacy and representation. Originality/value - The paper builds on previous definitions of public participation by underlining its collective character. In doing so, it develops the work by Parry, Moyser and Day by arguing that, in light of the empirical evidence presented in this issue, public participatory activities such as protests and demonstrations should no longer be labelled unconventional, but should instead be labelled as "contestatory participation". This is to better reflect a situation in which these modes of participation have become more conventional in many parts of the world.

    The World Wide Web (WWW) poses a distinct capability to offer interventions tailored to the individual's characteristics. To fine tune the tailoring process, studies are needed to explore how Internet accessibility and usage are related to demographic, psychosocial, behavioral, and other health related characteristics. This study was based on a cross-sectional survey conducted on 2373 7th grade students of various ethnic groups in Southern California. Measures of Internet use included Internet use at school or at home, Email use, chat-room use, and Internet favoring. Logistic regressions were conducted to assess the associations between Internet uses with selected demographic, psychosocial, behavioral variables and self-reported health statuses. The proportion of students who could access the Internet at school or home was 90% and 40%, separately. Nearly all (99%) of the respondents could access the Internet either at school or at home. Higher SES and Asian ethnicity were associated with higher internet use. Among those who could access the Internet and after adjusting for the selected demographic and psychosocial variables, depression was positively related with chat-room use and using the Internet longer than 1 hour per day at home, and hostility was positively related with Internet favoring (All ORs = 1.2 for +1 STD, p Internet use (ORs for +1 STD ranged from 1.2 to 2.0, all p Internet use. Substance use was positively related to email use, chat-room use, and at home Internet use (OR for "used" vs. "not used" ranged from 1.2 to 4.0, p Internet use at home but lower levels of Internet use at school. More physical activity was related to more email use (OR = 1.3 for +1 STD), chat room use (OR = 1.2 for +1 STD), and at school ever Internet use (OR = 1.2 for +1 STD, all p Internet use-related measures. In this ethnically diverse sample of Southern California 7(th) grade students, 99% could access the Internet at school and/or at home. This suggests that the Internet

    The role of consent for research use of health information is contentious. Most discussion has focused on when project-specific consent may be waived but, recently, a broader range of consent options has been entertained, including broad opt-in for multiple studies with restrictions and notification with opt-out. We sought to elicit public values in this matter and to work toward an agreement about a common approach to consent for use of personal information for health research through deliberative public dialogues. We conducted seven day-long public dialogues, involving 98 participants across Canada. Immediately before and after each dialogue, participants completed a fixed-response questionnaire rating individuals' support for 3 approaches to consent in the abstract and their consent choices for 5 health research scenarios using personal information. They also rated how confident different safeguards made them feel that their information was being used responsibly. Broad opt-in consent for use of personal information garnered the greatest support in the abstract. When presented with specific research scenarios, no one approach to consent predominated. When profit was introduced into the scenarios, consent choices shifted toward greater control over use. Despite lively and constructive dialogues, and considerable shifting in opinion at the individual level, at the end of the day, there was no substantive aggregate movement in opinion. Personal controls were among the most commonly cited approaches to improving people's confidence in the responsible use of their information for research. Because no one approach to consent satisfied even a simple majority of dialogue participants and the importance placed on personal controls, a mechanism should be developed for documenting consent choice for different types of research, including ways for individuals to check who has accessed their medical record for purposes other than clinical care.

    IRIS Data Services has the mission of providing efficient access to a wide variety of seismic and related geoscience data to the user community. With our vast archive of freely available data, we recognize that there is a constant challenge to provide data to scientists and students that are of a consistently useful level of quality. To address this issue, we began by undertaking a comprehensive survey of the data and generating metrics measurements that provide estimates of data quality. These measurements can inform the scientist of the level of suitability of a given set of data for their scientific investigation. They also serve as a quality assurance check for network operators, who can act on this information to improve their current recording or mitigate issues with already recorded data and metadata. Following this effort, IRIS Data Services is moving forward to focus on providing tools for the scientist that make it easier to access data of a quality and characteristic that suits their investigation. Data that fulfill this criterion are termed "research-ready". In addition to filtering data by type, geographic location, proximity to events, and specific time ranges, we will offer the ability to filter data based on specific quality assessments. These include signal-to-noise ratio measurements, data continuity, timing quality, absence of channel cross-talk, and potentially many other factors. Our goal is to ensure that the user receives only the data that meets their specifications and will not require extensive review and culling after delivery. We will present the latest developments of the MUSTANG automated data quality system and introduce the Research-Ready Data Sets (RRDS) service. Together these two technologies serve as a data quality assurance ecosystem that will provide benefit to the scientific community by aiding efforts to readily find appropriate and suitable data for use in any number of objectives.

    The Specialized Dental Clinics (SDCs) represent the first government initiative in Latin America aimed at providing specialized oral health services. This study sought to evaluate the organizational accessibility to specialized oral health care services in Brazil and to understand the factors that may be associated with accessibility from the user’s perspective. This epidemiological, cross-sectional and quantitative study was conducted by means of interviews with individuals who sought specialized public oral health services in the city of João Pessoa, Paraíba, Brazil, and consisted of a sample of 590 individuals. Users expressed a favorable view of the classification and resolutive nature of specialized services offered by Brazilian public health. The binary logistic regression analysis revealed weak points highlighting the difficulty involved in obtaining such treatments leading to unfavorable evaluations. In the resolutive nature item, difficulty in accessing the location, queues and lack of materials and equipment were highlighted as statistically significant unfavorable aspects. While many of the users considered the service to be resolutive, weaknesses were mentioned that need to be detected to promote improvements and to prevent other health models adopted worldwide from reproducing the same flaws.

    2016-01-01

    Full Text Available In the context of the global information economy, ready access to the Internet is critical to a city’s competitiveness, which has prompted a number of cities to launch plans to establish wireless networks. Most literature on the development of wireless cities focuses on cities in Western countries, and few have discussed how Chinese cities have adopted wireless technologies in their urban infrastructure development efforts. This paper examines recent development and spatial distribution of public Wi-Fi access in Shanghai, a leading business hub in China. We mapped Wi-Fi hotspots through the government sponsored “i-Shanghai” project and China Mobile Communications Corporation (CMCC. We find that while telecommunication providers have been proactively deploying WLAN (wireless local area network,a proxy of public Wi-Fi or wireless access hotspots in Shanghai, neither government sponsored WLAN hotspots nor facilities established by CMCC could cover the old traditional neighborhoods in the central city and sub-districts in remote rural areas. We also address the development of a more sustainable wireless city in Shanghai with a particular focus on digital divide and social equity issues.

    Adherence to vaccination campaigns can be negatively influenced by Web presence of unreliable information. Aim of study is qualitative and quantitative evaluation of Italian WebPages contents about vaccinations to address prevention strategies in countries that, like Italy, wouldn't like vaccination to be mandatory any longer In August 2011 two researchers conducted a Systematic Review in Italian WebPages about vaccination risks. First 100 results of 9 common search engines have been combined; pro and against pages were compared (CHI2, p vaccinations and 24% of them was written by Medical Doctors. All institutional pages (12%) were pro vaccinations but they resulted in less important positions. Against WebPages were different from pro ones in terms of use of emotional images, personal negative experiences, advertising purposes (books or alternative medicine products). Main criticism was: inefficacy, low safety profile and stakeholder's interests. This study would like to represent a useful tool for parents and Medical Doctors, especially because many of them are progressively more sceptical about vaccination practises. The great number of anti-vaccination movements on Italian Web should improve public health strategies in terms of "Evidence-Based prevention".

    Full Text Available The media landscape is undergoing radical changes, especially related to the process of digitalization and information circulation through the internet, which increases the number of web channels and the opportunity to access them using multiple devices, and decreases the expertise needed to produce them. In this new digital, multi-channel environment, radical innovation, diversification and media hybridization are revolutionizing television. For over fifty years the way that television is watched and produced has not changed significantly. Today the roles of producers and audiences have blurred because users are able to upload their contents independent of traditional intermediaries, and to create their own Web TV platforms in an inexpensive way. Claude Lévi Strauss in 1962 developed the concept of the bricoleur opposed to the concept of ingénieur. According to the author, the bricoleur is able to use any available tools stocked from previous experience in order to complete a project, even if these tools were not intended for the specific goal. Drusian and Riva (2010 have applied this concept to the digital context describing the features of a new communication actor: the bricoleur high-tech. In this paper, drawing on the concept of the high-tech bricoleur, we will investigate two different Italian Web Television projects, CrossingTv, a micro WebTV created in Bologna in 2006, and FEMI, the Italian federation of Micro web TVs created in 2008. These initiatives both require the bricoleur, but they differ with regard to aim and results. Through the exploration of these two case studies, this paper shows in which ways these Web TV experiences differ from traditional television, specifically, how these new TV platforms clouds the distinction between media producers and media consumers. Our findings highlight a paradigm shift in how television is produced: content is generated collaboratively through recursive feedback between producers and

    Full Text Available Since the enactment of the Americans with Disabilities Act (ADA, 1990, many impaired Americans are no longer disabled by socially condoned conditions in the built environment. However, many people with cognitive and neurological impairments continue to face significant barriers to access, due to disabling environmental hyper-sensitivity and sensory processing disorders. These people are equally protected under the ADA, therefore mitigation is required. Neuroarchitecture, where consideration of the impact of the built environment on the central nervous system informs design paradigms, must complement current ADA compliance guidelines. This paper serves to open the topic to discussion, and is a call for attention, and action, for the removal of these generally unrecognized barriers to access and the equal use and enjoyment of public facilities.

    During the upcoming Summer 2016 meeting of the ESIP Federation (July 19-22), OpenDAP will hold a Developers and Users Workshop. While a broad set of topics will be covered, a key focus is capitalizing on recent EOSDIS-sponsored advances in Hyrax, OPeNDAPs own software for server-side realization of the DAP2 and DAP4 protocols. These Hyrax advances are as important to data users as to data providers, and the workshop will include hands-on experiences of value to both. Specifically, a balanced set of presentations and hands-on tutorials will address advances in1.server installation,2.server configuration,3.Hyrax aggregation capabilities,4.support for data-access from clients that are HTTP-based, JSON-based or OGC-compliant (especially WCS and WMS),5.support for DAP4,6.use and extension of server-side computational capabilities, and7.several performance-affecting matters. Topics 2 through 7 will be relevant to data consumers, data providers and notably, due to the open-source nature of all OPeNDAP software to developers wishing to extend Hyrax, to build compatible clients and servers, and/or to employ Hyrax as middleware that enables interoperability across a variety of end-user and source-data contexts. A session for contributed talks will elaborate the topics listed above and embrace additional ones.

  14. Being a good spy: Legitimizing access to web-based observation

    Full Text Available Observation of online forums is a relevant methodological approach for researchers in several disciplines. However, ethical guidelines on such observations challenge the ethically concerned researcher. In this paper, I reflect on how I carried out my observation of an online weight-loss forum, and how I could have conducted it differently to meet ethical standards and the demands of high-quality research. After receiving approval from the forum administrators to observe the forum, information about my project on obesity was posted online. Some of the participants reacted negatively to my presence in the forum. This paper draws on the evolving discussion between researcher and participants on the complex issue of research ethics, particularly informed consent, in studying closed forums on the Internet. It is suggested that evaluating whether participants are harmed is more important than the public/private divide when considering whether informed consent is necessary.

  15. Intelligent Urban Public Transportation for Accessibility Dedicated to People with Disabilities

    Full Text Available The traditional urban public transport system generally cannot provide an effective access service for people with disabilities, especially for disabled, wheelchair and blind (DWB passengers. In this paper, based on advanced information & communication technologies (ICT and green technologies (GT concepts, a dedicated public urban transportation service access system named Mobi+ has been introduced, which facilitates the mobility of DWB passengers. The Mobi+ project consists of three subsystems: a wireless communication subsystem, which provides the data exchange and network connection services between buses and stations in the complex urban environments; the bus subsystem, which provides the DWB class detection & bus arrival notification services; and the station subsystem, which implements the urban environmental surveillance & bus auxiliary access services. The Mobi+ card that supports multi-microcontroller multi-transceiver adopts the fault-tolerant component-based hardware architecture, in which the dedicated embedded system software, i.e., operating system micro-kernel and wireless protocol, has been integrated. The dedicated Mobi+ embedded system provides the fault-tolerant resource awareness communication and scheduling mechanism to ensure the reliability in data exchange and service provision. At present, the Mobi+ system has been implemented on the buses and stations of line ‘2’ in the city of Clermont-Ferrand (France. The experiential results show that, on one hand the Mobi+ prototype system reaches the design expectations and provides an effective urban bus access service for people with disabilities; on the other hand the Mobi+ system is easily to deploy in the buses and at bus stations thanks to its low energy consumption and small form factor.

    State health departments have placed a tremendous amount of information, data, and services online in recent years. With the significant increase in online resources at official health sites, though, have come questions concerning equity of access and the confidentiality of electronic medical materials. This paper reports on an examination of public health department websites maintained by the 50 state governments. Using a content analysis of health department sites undertaken each year from 2000 to 2005, we investigate several dimensions of accessibility and privacy: readability levels, disability access, non-English accessibility, and the presence of privacy and security statements. We argue that although progress has been made at improving the accessibility and confidentiality of health department electronic resources, there remains much work to be done to ensure quality access for all Americans in the area of public e-health.
