    Full Text Available Abstract Background People with rheumatoid arthritis (RA should use DMARDs (disease-modifying anti-rheumatic drugs within the first three months of symptoms in order to prevent irreversible joint damage. However, recent studies report the delay in DMARD use ranges from 6.5 months to 11.5 months in Canada. While most health service delivery interventions are designed to improve the family physician's ability to refer to a rheumatologist and prescribe treatments, relatively little has been done to improve the delivery of credible, relevant, and user-friendly information for individuals to make treatment decisions. To address this care gap, the Animated, Self-serve, Web-based Research Tool (ANSWER will be developed and evaluated to assist people in making decisions about the use of methotrexate, a type of DMARD. The objectives of this project are: 1 to develop ANSWER for people with early RA; and 2 to assess the extent to which ANSWER reduces people's decisional conflict about the use of methotrexate, improves their knowledge about RA, and improves their skills of being 'effective healthcare consumers'. Methods/design Consistent with the International Patient Decision Aid Standards, the development process of ANSWER will involve: 1. creating a storyline and scripts based on the best evidence on the use of methotrexate and other management options in RA, and the contextual factors that affect a patient's decision to use a treatment as found in ERAHSE; 2. using an interactive design methodology to create, test, analyze and refine the ANSWER prototype; 3. testing the content and user interface with health professionals and patients; and 4. conducting a pilot study with 51 patients, who are diagnosed with RA in the past 12 months, to assess the extent to which ANSWER improves the quality of their decisions, knowledge and skills in being effective consumers. Discussion We envision that the ANSWER will help accelerate the dissemination of knowledge and

    The emergence of infectious diseases, caused by novel pathogens or the spread of existing ones to new populations and regions, represents a continuous threat to humans and other species. The early detection of emerging human, animal, and plant diseases is critical to preventing the spread of infection and protecting the health of our species and environment. Today, more than 75% of emerging infectious diseases are estimated to be zoonotic and capable of crossing species barriers and diminishing food supplies. Traditionally, surveillance of diseases has relied on a hierarchy of health professionals that can be costly to build and maintain, leading to a delay or interruption in reporting. However, Internet-based surveillance systems bring another dimension to epidemiology by utilizing technology to collect, organize, and disseminate information in a more timely manner. Partially and fully automated systems allow for earlier detection of disease outbreaks by searching for information from both formal sources (e.g., World Health Organization and government ministry reports) and informal sources (e.g., blogs, online media sources, and social networks). Web-based applications display disparate information online or disperse it through e-mail to subscribers or the general public. Web-based early warning systems, such as ProMED-mail, the Global Public Health Intelligence Network (GPHIN), and Health Map, have been able to recognize emerging infectious diseases earlier than traditional surveillance systems. These systems, which are continuing to evolve, are now widely utilized by individuals, humanitarian organizations, and government health ministries.

  4. A Web-based Simulator for Sample Size and Power Estimation in Animal Carcinogenicity Studies

    Full Text Available A Web-based statistical tool for sample size and power estimation in animal carcinogenicity studies is presented in this paper. It can be used to provide a design with sufficient power for detecting a dose-related trend in the occurrence of a tumor of interest when competing risks are present. The tumors of interest typically are occult tumors for which the time to tumor onset is not directly observable. It is applicable to rodent tumorigenicity assays that have either a single terminal sacrifice or multiple (interval sacrifices. The design is achieved by varying sample size per group, number of sacrifices, number of sacrificed animals at each interval, if any, and scheduled time points for sacrifice. Monte Carlo simulation is carried out in this tool to simulate experiments of rodent bioassays because no closed-form solution is available. It takes design parameters for sample size and power estimation as inputs through the World Wide Web. The core program is written in C and executed in the background. It communicates with the Web front end via a Component Object Model interface passing an Extensible Markup Language string. The proposed statistical tool is illustrated with an animal study in lung cancer prevention research.

  5. Attitudes toward the use of animals in chronic versus acute pain research: results of a web-based forum.

    When asked about the use of animals in biomedical research, people often state that the research is only acceptable if pain and distress are minimised. However, pain is caused when the aim is to study pain itself, resulting in unalleviated pain for many of the animals involved. Consequently, the use of animals in pain research is often considered contentious. To date, no research has explored people's views toward different types of animal-based pain research (e.g. chronic or acute pain). This study used a web-based survey to explore people's willingness to support the use of mice in chronic versus acute pain research. The majority of the participants opposed the use of mice for either chronic (68.3%) or acute (63.1%) pain research. There was no difference in the levels of support or opposition for chronic versus acute pain research. Unsupportive participants justified their opposition by focusing on the perceived lack of scientific merit, or the existence of non-animal alternatives. Supporters emphasised the potential benefits that could arise, with some stating that the benefits outweigh the costs. The majority of the participants were opposed to pain research involving mice, regardless of the nature and duration of the pain inflicted, or the perceived benefit of the research. A better understanding of public views toward animal use in pain research may provide a stronger foundation for the development of policy governing the use of animals in research where animals are likely to experience unalleviated pain.

User-needs assessment and usability testing are crucial elements in the iterative process of map design and implementation. This study presents the results of a usability test of static, animated and interactive maps of injury rates and socio-demographic determinants of injury by a sample of potential end-users in Toronto, Canada. The results of the user-testing suggest that different map types are useful for different purposes and for satisfying the varying skill level of the individual user. The static maps were deemed to be easy to use and versatile, while the animated maps could be made more useful if animation controls were provided. The split-screen concept of the interactive maps was highlighted as particularly effective for map comparison. Overall, interactive maps were identified as the preferred map type for comparing patterns of injury and related socio-demographic risk factors. Information collected from the user-tests is being used to expand and refine the injury web maps for Toronto, and could inform other public health-related geo-visualization projects.

    Molecular simulations offer important mechanistic and functional clues in studies of proteins and other macromolecules. However, interpreting the results of such simulations increasingly requires tools that can combine information from multiple structural databases and other web resources, and provide highly integrated and versatile analysis tools. Here, we present a new web server that integrates high-quality animation of molecular motion (MM) with structural and functional analysis of macromolecules. The new tool, dubbed POLYVIEW-MM, enables animation of trajectories generated by molecular dynamics and related simulation techniques, as well as visualization of alternative conformers, e.g. obtained as a result of protein structure prediction methods or small molecule docking. To facilitate structural analysis, POLYVIEW-MM combines interactive view and analysis of conformational changes using Jmol and its tailored extensions, publication quality animation using PyMol, and customizable 2D summary plots that provide an overview of MM, e.g. in terms of changes in secondary structure states and relative solvent accessibility of individual residues in proteins. Furthermore, POLYVIEW-MM integrates visualization with various structural annotations, including automated mapping of known inter-action sites from structural homologs, mapping of cavities and ligand binding sites, transmembrane regions and protein domains.

    2016-07-01

    Animal testing was used traditionally in the cosmetics industry to confirm product safety, but has begun to be banned; alternative methods to replace animal experiments are either in development, or are being validated, worldwide. Research data related to test substances are critical for developing novel alternative tests. Moreover, safety information on cosmetic materials has neither been collected in a database nor shared among researchers. Therefore, it is imperative to build and share a database of safety information on toxicological mechanisms and pathways collected through in vivo, in vitro, and in silico methods. We developed the CAMSEC database (named after the research team; the Consortium of Alternative Methods for Safety Evaluation of Cosmetics) to fulfill this purpose. On the same website, our aim is to provide updates on current alternative research methods in Korea. The database will not be used directly to conduct safety evaluations, but researchers or regulatory individuals can use it to facilitate their work in formulating safety evaluations for cosmetic materials. We hope this database will help establish new alternative research methods to conduct efficient safety evaluations of cosmetic materials.

    Recent studies suggest that the content of confabulation is mainly positive and self-enhancing. In this group study, we aimed to investigate whether this positive bias is specific to self-referent information. Confabulating amnesic patients, amnesic non-confabulating patients and healthy controls were asked to reproduce a series of short stories. We manipulated the emotional valence of the material by including positive, negative and neutral story plots. We also manipulated the self-reference of the material by including self-referent versus other-referent encoding instructions. Confabulating patients were as impaired as a group of amnesic patients in the amount of information they recalled, both groups being worse than healthy controls. Importantly, confabulating patients showed a selective bias in the negative self-referent condition, in that they recalled such information in a manner which portrayed a more positive image of themselves. This positive bias was not present in stories that were not encoded in a self-referent manner and it was not significantly correlated to patients' self-reported mood. We propose that both confabulation and its motivated content result from a deficit in the control and regulation of memory retrieval, which allows motivational factors to acquire a greater role than usual in determining which memories are selected for retrieval. To this extent, the self-enhancing content of confabulation could be explained as a neurogenic exaggeration of normal self-serving memory distortion.

    g-FLUA2H is a web-based application focused on the analysis of the dynamics of influenza virus animal-to-human (A2H) mutation transmissions. The application only requires the viral protein sequences from both the animal and human host populations as input datasets. The comparative analyses between the co-aligned sequences of the two viral populations is based on a sliding window approach of size nine for statistical significance and data application to the major histocompatibility complex (MHC) and T-cell receptor (TCR) immune response mechanisms. The sequences at each of the aligned overlapping nonamer positions for the respective virus hosts are classified as four patterns of characteristic diversity motifs, as a basis for quantitative analyses: (i) "index", the most prevalent sequence; (ii) "major" variant, the second most common sequence and the single most prevalent variant of the index, with at least one amino acid mutation; (iii) "minor" variants, multiple different sequences, each with an incidence (percent occurrence) less than that of the major variant; and (iv) "unique" variants, each with only one occurrence in the alignment. The diversity motifs and their incidences at each of the nonamer positions allow evaluation of the mutation transmission dynamics and selectivity of the viral sequences in relation to the animal and the human hosts. g-FLUA2H is facilitated by a grid back-end for parallel processing of large sequence datasets. The web-application is publicly available at http://bioinfo.perdanauniversity.edu.my/g-FLUA2H. It can be used for a detailed characterization of the composition and incidence of mutations present in the proteomes of influenza viruses from animal and human host populations, for a better understanding of host tropism.

    Considerable attention has been given lately to the need for global systems for animal disease surveillance that support real-time assessment of changing temporal-spatial risks. Until recently, however, prospects for development of such systems have been limited by the lack of informatics tools and an overarching collaboration framework to enable real-time data capturing, sharing, analysis, and related decision-making. In this paper, we present some of the tools of the FMD BioPortal System (www.fmd.ucdavis.edu/bioportal), which is a web-based system that facilitates near real-time information sharing, visualization, and advanced space-time cluster analysis for foot-and-mouth disease (FMD). Using this system, FMD information that is collected and maintained at various data acquisition and management sites around the world can be submitted to a data repository using various mutually agreed upon Extensible Markup Language (XML) formats, including Health Level Seven (HL7). FMD BioPortal makes available a set of advanced space-time cluster analysis techniques, including scan statistic-based methods and machine learning-based clustering methods. These techniques are aimed at identifying local clusters of disease cases in relation to the background risk. Data and analysis results can be displayed using a novel visualization environment, which supports multiple views including GIS, timeline, and periodical patterns. All FMD BioPortal functionalities are accessible through the Web and data confidentiality can be secured through user access control and computer network security techniques such as Secure Sockets Layer (SSL). FMD BioPortal is currently operational with limited data routinely collected by the Office International des Epizooties, the GenBank, the FMD World Reference Laboratory in Pirbright, and by the FMD Laboratory at the University of California in Davis. Here we describe technical attributes and capabilities of FMD BioPortal and illustrate its functionality

    Full Text Available In classical uncapacitated facility location problems (UFLP the goal is to satisfy requirements of some demand points by setting up some servers, among potential facility locations, such that the total cost including service costs and fixed costs are minimized. In this paper a generalization of UFLP is considered in which some demand points, called self-serving, could be served exclusively by a new server at that point. Numerical experiments show that near optimal solutions are achieved by the proposed method.

    Traditionally, the self-serving bias has been investigated in ambiguous contexts in which participants work on tasks that measure novel abilities before making attributions without clear criteria for success or failure feedback. Prior studies have confirmed that the self-serving bias is pervasive in the general population, yet it varies significantly across situations involving ambiguous contexts. The present study features an unambiguous context encompassing interpersonal events that involved implicit causality (with the “self” as an actor or recipient), the inherent logic of which indicated attribution criteria. The aim of this study was to explore whether there is a self-serving bias in unambiguous contexts and to examine whether it is as sensitive to situation as it has been shown to be in ambiguous contexts. The results showed that, in an unambiguous context, participants exhibited self-serving bias in relation to attribution associated with negative interpersonal events. Additionally, the self-serving bias was greater in the actor condition relative to the recipient condition (Study 1), and this effect was not affected by the level of self-awareness, which was manipulated by the use or otherwise of a camera during the experiment (Study 2). Our findings provide evidence for the existence of the self-serving bias in unambiguous contexts. Moreover, the self-serving bias was shown to be immune to situation in unambiguous contexts, but it did depend on factors associated with the events per se, such as the actor versus recipient role that the self played in interpersonal events.

    2013-05-01

    This article provides an answer to the question of why agents make self-serving decisions under moral hazard and how their self-serving decisions can be kept in check through institutional arrangements. Our theoretical model predicts that the agents' power and the manner in which they are held accountable jointly determine their propensity to make self-serving decisions. We test our theory in the context of financial investment decisions made under moral hazard using others' funds. Across 3 studies, using different decision-making tasks, different manipulations of power and accountability, and different samples, we show that agents' power makes them more likely to behave in a self-serving manner under moral hazard, but only when the appropriate accountability mechanisms are not in place. Specifically, we distinguish between outcome and procedural accountability and show that holding agents accountable for their decision-making procedure reduces the level of self-serving decisions under moral hazard and also curbs the negative consequences of power. Implications for decisions under moral hazard, the psychology of power, and the accountability literature are discussed.

    Directory of Open Access Journals (Sweden)

    Peter H. Kriss

    2011-10-01

    Full Text Available Slowing climate change will almost certainly require a reduction in greenhouse gas emissions, but agreement on who should reduce emissions by how much is difficult, in part because of the self-serving bias---the tendency to believe that what is beneficial to oneself is also fair. Conducting surveys among college students in the United States and China, we show that each of these groups displays a nationalistic self-serving bias in judgments of a fair distribution of economic burdens resulting from mitigation. Yet, we also show, by disguising the problem and the identity of the parties, that it is possible to elicit perceptions of fairness that are not influenced by national interests. Our research reveals that the self-serving bias plays a major role in the difficulty of obtaining agreement on how to implement emissions reductions. That is, the disagreement over what constitutes fair climate policy does not appear to be due to cross-national differences in what constitutes a fair distribution of burdens. Interventions to mitigate the self-serving bias may facilitate agreement.

    The research work on Web-based long-distance data acquisition (DAQ) is valuable for application to tele-detection machine faults. With an expert system for machine fault detection, faults in a distantly located machine can be diagnosed through the internet. The distant user logs on to the expert system Web page, fills in the requirements, and starts-up the diagnose process. The system then connects to the DAQ server that is installed in the machine, samples data required for diagnoses through the internet, and sends back diagnose results. In such a long-distance system, Web-based DAQ plays an important role by automatic sampling and transferring of data through the internet. We have built an experimental data acquisition system using a National Instruments AT-MIO-16E-10 board running under Ch language environment. In this experimental example, the user can acquire data online. The principle of this experimental method is introduced in this paper. A detailed programming technique is described with an example.

    Giudicepietro, F.; Meglio, V.; Romano, S. P.; de Cesare, W.; Ventre, G.; Martini, M.

    Over the last few decades the seismological monitoring systems have dramatically improved tanks to the technological advancements and to the scientific progresses of the seismological studies. The most modern processing systems use the network tech- nologies to realize high quality performances in data transmission and remote controls. Their architecture is designed to favor the real-time signals analysis. This is, usually, realized by adopting a modular structure that allow to easy integrate any new cal- culation algorithm, without affecting the other system functionalities. A further step in the seismic processing systems evolution is the large use of the web based appli- cations. The web technologies can be an useful support for the monitoring activities allowing to automatically publishing the results of signals processing and favoring the remote access to data, software systems and instrumentation. An application of the web technologies to the seismological monitoring has been developed at the "Os- servatorio Vesuviano" monitoring center (INGV) in collaboration with the "Diparti- mento di Informatica e Sistemistica" of the Naples University. A system named Web Based Seismological Monitoring (WBSM) has been developed. Its main objective is to automatically publish the seismic events processing results and to allow displaying, analyzing and downloading seismic data via Internet. WBSM uses the XML tech- nology for hypocentral and picking parameters representation and creates a seismic events data base containing parametric data and wave-forms. In order to give tools for the evaluation of the quality and reliability of the published locations, WBSM also supplies all the quality parameters calculated by the locating program and allow to interactively display the wave-forms and the related parameters. WBSM is a modular system in which the interface function to the data sources is performed by two spe- cific modules so that to make it working in conjunction with a

  13. Leader power and leader self-serving behavior: The role of effective leadership beliefs and performance information

    OpenAIRE

    Rus, Diana; Knippenberg, Daan; Wisse, Barbara

    2010-01-01

    International audience; In this research we investigated the role played by leader power in determining leader self-serving behavior. Based on an integration of insights from research on the determinants of leader behavior and the power-approach theory, we hypothesized that with higher leader power leader self-serving behavior is determined more by internal states like effective leadership beliefs and less by external cues like performance information. We found support for this prediction acr...

    Diffusion of responsibility across agents has been proposed to underlie decreased helping and increased aggression in group behaviour. However, few studies have directly investigated effects of the presence of other people on how we experience the consequences of our actions. This EEG study investigated whether diffusion of responsibility simply reflects a post-hoc self-serving bias, or rather has direct effects on how we process the outcomes of our actions, and our experience of agency over them. Participants made voluntary actions whose outcomes were more or less negative. Presence of another potential agent reduced participants' sense of agency over those outcomes, even though it was always obvious who caused each outcome. Further, presence of another agent reduced the amplitude of feedback-related negativity evoked by outcome stimuli, suggesting reduced outcome monitoring. The presence of other agents may lead to diffusion of responsibility by weakening the neural linkage between one's actions and their outcomes.

  15. Self-Serving Bias or Simply Serving the Self? Evidence for a Dimensional Approach to Narcissism.

    Tamborski, Michael; Brown, Ryan P; Chowning, Karolyn

    2012-06-01

    Previous research has suggested that narcissism can be conceptualized as a multidimensional construct consisting of the related, but unique, dimensions of grandiosity and entitlement. The current studies examined the divergent associations of grandiosity and entitlement with respect to different types of self-serving strategies. In Study 1, we found that narcissistic grandiosity, but not entitlement, was positively associated with a self-enhancing strategy of unrealistic optimism. This association was not mediated by self-esteem. In Study 2, narcissistic entitlement, but not grandiosity, was predictive of unethical decision-making, an interpersonal self-promotional strategy that advances the self at the expense of others. Together, both studies support a model of narcissism consisting of a relatively intrapersonal dimension of grandiosity and a relatively interpersonal dimension of entitlement.

  16. Web-based Altimeter Service

    2010-12-01

    We have developed a web-based system to allow updating and subsetting of TOPEX data. The Altimeter Service will be operated by PODAAC along with their other provision of oceanographic data. The Service could be easily expanded to other mission data. An Altimeter Service is crucial to the improvement and expanded use of altimeter data. A service is necessary for altimetry because the result of most interest - sea surface height anomaly (SSHA) - is composed of several components that are updated individually and irregularly by specialized experts. This makes it difficult for projects to provide the most up-to-date products. Some components are the subject of ongoing research, so the ability for investigators to make products for comparison or sharing is important. The service will allow investigators/producers to get their component models or processing into widespread use much more quickly. For coastal altimetry, the ability to subset the data to the area of interest and insert specialized models (e.g., tides) or data processing results is crucial. A key part of the Altimeter Service is having data producers provide updated or local models and data. In order for this to succeed, producers need to register their products with the Altimeter Service and to provide the product in a form consistent with the service update methods. We will describe the capabilities of the web service and the methods for providing new components. Currently the Service is providing TOPEX GDRs with Retracking (RGDRs) in netCDF format that has been coordinated with Jason data. Users can add new orbits, tide models, gridded geophysical fields such as mean sea surface, and along-track corrections as they become available and are installed by PODAAC. The updated fields are inserted into the netCDF files while the previous values are retained for comparison. The Service will also generate SSH and SSHA. In addition, the Service showcases a feature that plots any variable from files in netCDF. The

    Chronic cocaine use has been associated with impairments in social cognition, self-serving and antisocial behavior, and socially relevant personality disorders (PD). Despite the apparent relationship between Machiavellianism and stimulant use, no study has explicitly examined this personality concept in cocaine users so far. In the frame of the longitudinal Zurich Cocaine Cognition Study, the Machiavellianism Questionnaire (MACH-IV) was assessed in 68 recreational and 30 dependent cocaine users as well as in 68 psychostimulant-naïve controls at baseline. Additionally, three closely related personality dimensions from the Temperament and Character Inventory (TCI)–cooperativeness, (social) reward dependence, and self-directedness–and the screening questionnaire of the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II) were acquired. At the one-year follow-up, 57 cocaine users and 48 controls were reassessed with the MACH-IV. Finally, MACH-IV scores were correlated with measures of social cognition and interaction (cognitive/emotional empathy, Theory-of-Mind, prosocial behavior) and with SCID-II PD scores assessed at baseline. Both recreational and dependent cocaine users showed significantly higher Machiavellianism than controls, while dependent cocaine users additionally displayed significantly lower levels of TCI cooperativeness and self-directedness. During the one-year interval, MACH-IV scores showed high test-retest reliability and also the significant gap between cocaine users and controls remained. Moreover, in cocaine users, higher Machiavellianism correlated significantly with lower levels of cooperativeness and self-directedness, with less prosocial behavior, and with higher cluster B PD scores. However, Machiavellianism was not correlated with measures of cocaine use severity (r<-.15). Both recreational and dependent cocaine users display pronounced and stable Machiavellian personality traits. The lack of correlations

    Blackwood, N J; Bentall, R P; ffytche, D H; Simmons, A; Murray, R M; Howard, R J

    2003-10-01

    We use causal attributions to infer the most likely cause of events in the social world. Internal attributions imply self-responsibility for events. The self-serving bias describes the tendency of normal subjects to attribute the causation of positive events internally ("I am responsible em leader ") and negative events externally ("Other people or situational factors are responsible em leader "). The self-serving bias has been assumed to serve a positive motivational function by enhancing self-esteem. Abnormalities of attributional style have been implicated in both depression and psychosis. We examined the neural basis of both self-responsibility and the self-serving bias using functional magnetic resonance imaging during the performance of attributional decision tasks. We found that the determination of self-responsibility recruits areas previously implicated in action simulation (bilateral premotor cortex and cerebellum), suggesting that such higher order social cognition is related to simpler internal models of goal-directed action. The dorsal striatum, previously implicated in motivated behavior, mediates the self-serving bias.

    Full Text Available Decreased privacy is an unavoidable consequence in the drive to make the world a more secure, safer place, according to some analysts. In the on-line world, the conflict between privacy and security manifests itself in a debate between anonymity and accountability. Balance between Anonymity and Accountability is a major concern in web based transactions. The protection of users’ privacy when performing web-based transactions is an important factor in the acceptance and use of Internet and web services. There is a tremendous improvement in the automation of the way we pay for goods and services by the variety and growth of electronic banking services available to the consumers. Hence there is a need for the ultimate structure of the new electronic transaction system that has a substantial impact on the personal privacy as well as on the nature and extent of criminal use of E- transactions. This paper presents an approach for such structure.

    Full Text Available This paper presents an overview about the evaluation of risks and vulnerabilities in a web based distributed application by emphasizing aspects concerning the process of security assessment with regards to the audit field. In the audit process, an important activity is dedicated to the measurement of the characteristics taken into consideration for evaluation. From this point of view, the quality of the audit process depends on the quality of assessment methods and techniques. By doing a review of the fields involved in the research process, the approach wants to reflect the main concerns that address the web based distributed applications using exploratory research techniques. The results show that many are the aspects which must carefully be worked with, across a distributed system and they can be revealed by doing a depth introspective analyze upon the information flow and internal processes that are part of the system. This paper reveals the limitations of a non-existing unified security risk assessment model that could prevent such risks and vulnerabilities debated. Based on such standardize models, secure web based distributed applications can be easily audited and many vulnerabilities which can appear due to the lack of access to information can be avoided.

    The AIRSAR automated, Web-based data processing and distribution system is an integrated, end-to-end synthetic aperture radar (SAR) processing system. Designed to function under limited resources and rigorous demands, AIRSAR eliminates operational errors and provides for paperless archiving. Also, it provides a yearly tune-up of the processor on flight missions, as well as quality assurance with new radar modes and anomalous data compensation. The software fully integrates a Web-based SAR data-user request subsystem, a data processing system to automatically generate co-registered multi-frequency images from both polarimetric and interferometric data collection modes in 80/40/20 MHz bandwidth, an automated verification quality assurance subsystem, and an automatic data distribution system for use in the remote-sensor community. Features include Survey Automation Processing in which the software can automatically generate a quick-look image from an entire 90-GB SAR raw data 32-MB/s tape overnight without operator intervention. Also, the software allows product ordering and distribution via a Web-based user request system. To make AIRSAR more user friendly, it has been designed to let users search by entering the desired mission flight line (Missions Searching), or to search for any mission flight line by entering the desired latitude and longitude (Map Searching). For precision image automation processing, the software generates the products according to each data processing request stored in the database via a Queue management system. Users are able to have automatic generation of coregistered multi-frequency images as the software generates polarimetric and/or interferometric SAR data processing in ground and/or slant projection according to user processing requests for one of the 12 radar modes.

    Papamichael, Konstantinos; Lai, Judy; Fuller, Daniel; Tariq, Tara

    2002-05-06

    This paper is about a web-based ''virtual lighting simulator,'' which is intended to allow architects and lighting designers to quickly assess the effect of key parameters on the daylighting and lighting performance in various space types. The virtual lighting simulator consists of a web-based interface that allows navigation through a large database of images and data, which were generated through parametric lighting simulations. At its current form, the virtual lighting simulator has two main modules, one for daylighting and one for electric lighting. The daylighting module includes images and data for a small office space, varying most key daylighting parameters, such as window size and orientation, glazing type, surface reflectance, sky conditions, time of the year, etc. The electric lighting module includes images and data for five space types (classroom, small office, large open office, warehouse and small retail), varying key lighting parameters, such as the electric lighting system, surface reflectance, dimming/switching, etc. The computed images include perspectives and plans and are displayed in various formats to support qualitative as well as quantitative assessment. The quantitative information is in the form of iso-contour lines superimposed on the images, as well as false color images and statistical information on work plane illuminance. The qualitative information includes images that are adjusted to account for the sensitivity and adaptation of the human eye. The paper also includes a section on the major technical issues and their resolution.

    2001-01-01

    Tribology design is one of the most important parts of mechanical product design as thestrength design. Unfortunately, because tribology design knowledge is often m ulti-disciplinary,complicated and piecemeal, it is therefore difficult for a mechanical designer to capture the neededtribology design knowledge. The concept of tribology design repository is proposed in this paper totry to address this problem. This paper presents an object-oriented knowledge representation lan-guage based on the modeling of tribology design component and it makes the complicated tribol-ogy knowledge represented has such advantages as inheritance, encapsulation, and consistency.A web-based triblogy design repository is then established and it enables the edition, retrieve,sharing and reuse of corporate tribology design knowledge in the repository from the Internet.

  16. Web Based Video Educational Resources for Surgeons

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available During the last years, video files showing different surgical procedures have become extremely available and popular on the internet. They are available on both free and unrestricted sites, as well as on dedicated sites which control the medical quality of the information. Honest presentation and a minimal video-editing to include information about the procedure are mandatory to achieve a product with a true educational value. The integration of the web-based video educational resources in the continuing medical information system seems to be limited and the true educational impact very difficult to assess. A review of the available literature dedicated on this subject shows that the main challenge is related to the human factor and not to the available technology.

  17. Web-Based Learning - Yes We Can!

    Science.gov (United States)

    Schroeder, Ulrik

    Web-based Learning has become a matter of fact at universities. We are now at the edge of new developments with Web 2.0 applications and social software is radically changing the way of how we communicate and share in social networks. Can we expect an analogous revolution for university education 2.0? I will give some arguments that I rather expect an incremental evolution than a radical change. First, I take a look at current eLearning implementations and organizational frameworks and give an example from RWTH Aachen University. Against the background of cognitive theories the utilization of Web 2.0 applications are promising to strengthen 21st century learning. But methods and tools must be adapted to the context of institutional learning as well as the formal regulations must be adjusted vice versa.

  2. Web-Based Training Applications in Safeguards and Security

    Energy Technology Data Exchange (ETDEWEB)

    Lopez, R.L.

    1999-05-21

    The U.S. Department of Energy (DOE) requires all employees who hold a security clearance and have access to classified information and/or special nuclear material to be trained in the area of Safeguards and Security. Since the advent of the World Wide Web, personnel who are responsible for training have capitalized on this communication medium to develop and deliver Web-based training. Unlike traditional computer based training where the student was required to find a workstation where the training program resided, one of Web-based training strongest advantage is that the training can be delivered right to the workers desk top computer. This paper will address reasons for the driving forces behind the utilization of Web-based training at the Laboratory with a brief explanation of the different types of training conducted. Also discussed briefly is the different types of distance learning used in conjunction with Web-based training. The implementation strategy will be addressed and how the Laboratory utilized a Web-Based Standards Committee to develop standards for Web-based training applications. Web-based problems resulting from little or no communication between training personnel across the Laboratory will be touched on and how this was solved. Also discussed is the development of a ''Virtual Training Center'' where personnel can shop on-line for their training needs. Web-based training programs within the Safeguards and Security arena will be briefly discussed. Specifically, Web-based training in the area of Materials Control and Accountability will be explored. A Web-based example of what a student would experience during a training session is also discussed. A short closing statement of what the future of Web-based Training holds in the future is offered.

    2004-01-01

    Web-based education has been enjoying greater popularity because of its undeniable advantages. It has been seen as a panacea by more and more people in educational field, including language teaching. Based on the realization of the great potential brought by the development of technology, some viewpoints about the relationship among technology, teaching and pedagogy are put forward: firstly, technology is a tool, not a strategy; secondly, pedagogical concerns and theory should drive the way technology is used in education, not the other way around; thirdly, what matters more than technology is how the technology is used for learning, and how it is integrated into the daily classroom scheme so that active engagement in acquisition-oriented work take place; and finally, the change of learning environment inevitably calls for parallel changes in teaching and learning procedures. Available technologies can greatly enhance both student-teacher and student-student interaction and can afford students increased opportunities for self directed learning. To be most effective, technology must be used to support well-planned curricular goals and should involve carefully designed activities providing students with meaningful educational experiences.

  9. Chapter 14: Web-based Tools - WESIX

    Science.gov (United States)

    Krughoff, K. S.; Connolly, A. J.

    We present here the design and features of the Web Enabled Source Identifier with X-Matching (WESIX). With the proliferation of large imaging surveys, it has become increasingly apparent that tasks performed frequently by astronomers need to be made available in a web-aware manner. The reasons for this are twofold: First, it is no longer feasible to work with the complete data sets. Calculations are much more efficient if they can be carried out at the data center where large files can be transferred quickly. Second, exploratory science can be greatly facilitated by combining common tasks into integrated web services. WESIX addresses both of these issues. It is deployable to large data centers where source identification can be carried out at the data source. In addition, WESIX can transparently leverage the capabilities of Open SkyQuery to crossmatch with large catalogs. The result is a web-based service that integrates object detection with the ability to crossmatch against published catalog data. In this chapter we will discuss how WESIX is constructed, its functionality and some example usage. Section 1 will give a brief overview of the architecture of the service. Section 2 will introduce the features of the service through both the web browser and SOAP web service interfaces. Section 3 gives a detailed overview of the web service methods. Section 4 walks through the example client distributed with the software package.

    Full Text Available Technology is advancing at a rapid pace, and what we knew a year ago is likely to no longer apply today. With it, the technology brings new ways of transmitting information, machining and processing, storage and socializing. The continuous development of information technologies contributes more than ever to the increase of access to information for any field of activity, including education. For this reason, education must help young people (pupils and students to collect and select from the sheer volume of information available, to access them and learn how to use them. Therefore, education must constantly adapt to social change; it must pass on the achievements and richness of human experience. At the same time, technology supports didactic activity because it leads learning beyond the classroom, involving all actors in the school community and prepares young people for their profession. Moreover, web tools available for education can yield added benefits, which is why, especially at higher levels of the education system, their integration starts being more obvious and the results are soon to be seen. Moreover, information technologies produce changes in the classic way of learning, thus suffering rapid and profound transformations. In addition, current information technologies offer many types of applications, representing the argument for a new system of providing education and for building knowledge. In this regard, the paper aims to highlight the impact and benefits of current information technologies, particularly web-based, on the educational process.

    Full Text Available This paper presents an approach for classifying students in order to predict their final grade based on features extracted from logged data in an education web-based system. A combination of multiple classifiers leads to a significant improvement in classification performance. Through weighting the feature vectors using a Genetic Algorithm we can optimize the prediction accuracy and get a marked improvement over raw classification. It further shows that when the number of features is few; feature weighting is works better than just feature selection. Many leading educational institutions are working to establish an online teaching and learning presence. Several systems with different capabilities and approaches have been developed to deliver online education in an academic setting. In particular, Michigan State University (MSU has pioneered some of these systems to provide an infrastructure for online instruction. The research presented here was performed on a part of the latest online educational system developed at MSU, the Learning Online Network with Computer-Assisted Personalized Approach (LON-CAPA

    2010-08-01

    Tailoring information to the needs of the learner is an important strategy in contemporary education settings. Web-based learning support, informed by multimedia theory, comprising interactive quizzes, glossaries with audio, short narrated Power Point(R) presentations, animations and digitised video clips were introduced in a first year Bachelor of Nursing biological sciences subject at a university in metropolitan Sydney. All students enrolled in this unit were invited to obtain access to the site and the number of hits to the site was recorded using the student tracking facility available on WebCT, an online course delivery tool adopted widely by many educational institutions and used in this study. Eighty-five percent of students enrolled in the subject accessed the learning support site. Students' perception of the value of a learning support site was assessed using a web-based survey. The survey was completed by 123 participants, representing a response rate of 22%. Three themes emerged from the qualitative data concerning nursing students' perception of the web-based activities: 'enhances my learning', 'study at my own pace', and 'about the activities: what I really liked/disliked'. Web-based interventions, supplementing a traditionally presented nursing science course were perceived by students to be beneficial in both learning and language development. Although students value interactive, multimedia learning they were not ready to completely abandon traditional modes of learning including face-to-face lectures. The findings of this study contribute to an understanding of how web-based resources can be best used to support students' learning in bioscience.

    Gibbon, Carolyn; Currie, Richard

    2008-01-01

    Problem-based learning (PBL) or enquiry-based learning (EBL) methods are frequently used within UK nursing curricula in order to support students in their learning. At the same time students are increasingly using electronic resources for information to support their learning. Following a successful Fund for the Development of Teaching (FDTL-phase 4) award, the Students Online in Nursing Integrated Curricula (SONIC) project ran from 2002 to 2005. This project developed and evaluated web-based resource-enriched scenarios to support students using PBL or EBL. This collaborative project across four institutions also included another six institutions in the evaluations. To facilitate evaluation a workbook was devised enabling data to be obtained from a total of 241 students from across different branches. Evaluations showed that they welcomed the open access and particular resources such as the animations, the hyperlinks, and the self-assessment quizzes. Whilst the evaluations did not ascertain the impact on students' learning, they nevertheless demonstrate that the students themselves regarded the resources as supplemental to, rather than substituting other approaches to learning. The development of these resources took place in nursing departments and interest has been demonstrated by a number of other professions nationally and internationally.

  16. Web Based Tool for Mission Operations Scenarios

    Science.gov (United States)

    Boyles, Carole A.; Bindschadler, Duane L.

    2008-01-01

    A conventional practice for spaceflight projects is to document scenarios in a monolithic Operations Concept document. Such documents can be hundreds of pages long and may require laborious updates. Software development practice utilizes scenarios in the form of smaller, individual use cases, which are often structured and managed using UML. We have developed a process and a web-based scenario tool that utilizes a similar philosophy of smaller, more compact scenarios (but avoids the formality of UML). The need for a scenario process and tool became apparent during the authors' work on a large astrophysics mission. It was noted that every phase of the Mission (e.g., formulation, design, verification and validation, and operations) looked back to scenarios to assess completeness of requirements and design. It was also noted that terminology needed to be clarified and structured to assure communication across all levels of the project. Attempts to manage, communicate, and evolve scenarios at all levels of a project using conventional tools (e.g., Excel) and methods (Scenario Working Group meetings) were not effective given limitations on budget and staffing. The objective of this paper is to document the scenario process and tool created to offer projects a low-cost capability to create, communicate, manage, and evolve scenarios throughout project development. The process and tool have the further benefit of allowing the association of requirements with particular scenarios, establishing and viewing relationships between higher- and lower-level scenarios, and the ability to place all scenarios in a shared context. The resulting structured set of scenarios is widely visible (using a web browser), easily updated, and can be searched according to various criteria including the level (e.g., Project, System, and Team) and Mission Phase. Scenarios are maintained in a web-accessible environment that provides a structured set of scenario fields and allows for maximum

    Portillo, Carmen J; Holzemer, William L; Slaughter, Rob; McGhee, Eva M

    2004-01-01

    Background A primary focus of self-care interventions for chronic illness is the encouragement of an individual's behavior change necessitating knowledge sharing, education, and understanding of the condition. The use of the Internet to deliver Web-based interventions to patients is increasing rapidly. In a 7-year period (1996 to 2003), there was a 12-fold increase in MEDLINE citations for “Web-based therapies.” The use and effectiveness of Web-based interventions to encourage an individual's change in behavior compared to non-Web-based interventions have not been substantially reviewed. Objective This meta-analysis was undertaken to provide further information on patient/client knowledge and behavioral change outcomes after Web-based interventions as compared to outcomes seen after implementation of non-Web-based interventions. Methods The MEDLINE, CINAHL, Cochrane Library, EMBASE, ERIC, and PSYCHInfo databases were searched for relevant citations between the years 1996 and 2003. Identified articles were retrieved, reviewed, and assessed according to established criteria for quality and inclusion/exclusion in the study. Twenty-two articles were deemed appropriate for the study and selected for analysis. Effect sizes were calculated to ascertain a standardized difference between the intervention (Web-based) and control (non-Web-based) groups by applying the appropriate meta-analytic technique. Homogeneity analysis, forest plot review, and sensitivity analyses were performed to ascertain the comparability of the studies. Results Aggregation of participant data revealed a total of 11,754 participants (5,841 women and 5,729 men). The average age of participants was 41.5 years. In those studies reporting attrition rates, the average drop out rate was 21% for both the intervention and control groups. For the five Web-based studies that reported usage statistics, time spent/session/person ranged from 4.5 to 45 minutes. Session logons/person/week ranged from 2

    Zhao, Peng; Lavoie, Jaie; Lavoie, Beau James; Simoes, Eduardo

    2017-01-01

    Background Health care is changing with a new emphasis on patient-centeredness. Fundamental to this transformation is the increasing recognition of patients' role in health care delivery and design. Medical appointment scheduling, as the starting point of most non-urgent health care services, is undergoing major developments to support active involvement of patients. By using the Internet as a medium, patients are given more freedom in decision making about their preferences for the appointments and have improved access. Objective The purpose of this study was to identify the benefits and barriers to implement Web-based medical scheduling discussed in the literature as well as the unmet needs under the current health care environment. Methods In February 2017, MEDLINE was searched through PubMed to identify articles relating to the impacts of Web-based appointment scheduling. Results A total of 36 articles discussing 21 Web-based appointment systems were selected for this review. Most of the practices have positive changes in some metrics after adopting Web-based scheduling, such as reduced no-show rate, decreased staff labor, decreased waiting time, and improved satisfaction, and so on. Cost, flexibility, safety, and integrity are major reasons discouraging providers from switching to Web-based scheduling. Patients’ reluctance to adopt Web-based appointment scheduling is mainly influenced by their past experiences using computers and the Internet as well as their communication preferences. Conclusions Overall, the literature suggests a growing trend for the adoption of Web-based appointment systems. The findings of this review suggest that there are benefits to a variety of patient outcomes from Web-based scheduling interventions with the need for further studies. PMID:28446422

Medical appointment scheduling, as the starting point of most non-urgent health care services, is undergoing major developments to support active involvement of patients. By using the Internet as a medium, patients are given more freedom in decision making about their preferences for the appointments and have improved access. The purpose of this study was to identify the benefits and barriers to implement Web-based medical scheduling discussed in the literature as well as the unmet needs under the current health care environment. In February 2017, MEDLINE was searched through PubMed to identify articles relating to the impacts of Web-based appointment scheduling. A total of 36 articles discussing 21 Web-based appointment systems were selected for this review. Most of the practices have positive changes in some metrics after adopting Web-based scheduling, such as reduced no-show rate, decreased staff labor, decreased waiting time, and improved satisfaction, and so on. Cost, flexibility, safety, and integrity are major reasons discouraging providers from switching to Web-based scheduling. Patients' reluctance to adopt Web-based appointment scheduling is mainly influenced by their past experiences using computers and the Internet as well as their communication preferences. Overall, the literature suggests a growing trend for the adoption of Web-based appointment systems. The findings of this review suggest that there are benefits to a variety of patient outcomes from Web-based scheduling interventions with the need for further studies.

    Participation in biobanking among individuals with familial risk for hereditary cancer (IFRs) and underserved/minority populations is vital for biobanking research. To address gaps in researcher knowledge regarding ethical concerns of these populations, we developed a web-based curriculum. Based on formative research and expert panel assessments, a curriculum and website was developed in an integrative, systematic manner. Researchers were recruited to evaluate the curriculum. Public health graduate students were recruited to pilot test the curriculum. All 14 researchers agreed the curriculum was easy to understand, adequately addressed the domains, and contained appropriate post-test questions. The majority evaluated the dialgoue animations as interesting and valuable. Twenty-two graduate students completed the curriculum, and 77 % improved their overall test score. A web-based curriculum is an acceptable and effective way to provide information to researchers about vulnerable populations' biobanking concerns. Future goals are to incorporate the curriculum with larger organizations.

  9. The Effectiveness of Web-Based Instruction: An Initial Inquiry

    Full Text Available As the use of Web-based instruction increases in the educational and training domains, many people have recognized the importance of evaluating its effects on student outcomes such as learning, performance, and satisfaction. Often, these results are compared to those of conventional classroom instruction in order to determine which method is “better.” However, major differences in technology and presentation rather than instructional content can obscure the true relationship between Web-based instruction and these outcomes. Computer-based instruction (CBI, with more features similar to Web-based instruction, may be a more appropriate benchmark than conventional classroom instruction. Furthermore, there is little consensus as to what variables should be examined or what measures of learning are the most appropriate, making comparisons between studies difficult and inconclusive. In this article, we review the historical findings of CBI as an appropriate benchmark to Web-based instruction. In addition, we review 47 reports of evaluations of Web-based courses in higher education published between 1996 and 2002. A tabulation of the documented findings into eight characteristics is offered, along with our assessments of the experimental designs, effect sizes, and the degree to which the evaluations incorporated features unique to Web-based instruction.

    The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG). 68 refs.

    The aim of the present paper was to study preferences for web based self-administered questionnaires (web SAQs) vs. paper-based self-administered questionnaires (paper SAQs) and to evaluate the feasibility of using web SAQs in patients referred to cardiac, lung, occupational and cancer rehabilitation programs. The patients were approached by mail and given the choice to answer the compulsory SAQs either on paper or on a web-based platform. Hundred and twenty seven out of 183 eligible patients (69.3%) were willing to participate and 126 completed the study. Web SAQs were preferred by 77.7%, and these patients were significantly younger, more often cohabiting and tended to have higher level of education than paper SAQ users. Mean number of data missing per patient was less among the web SAQ users than the paper SAQ users (0.55 vs. 2.15, p questionnaires on internet platforms when internet access is common and available. Implications for Rehabilitation The high acceptability of web-based self-administered questionnaires among rehabilitation patients suggests that internet platforms are suitable tools to collect patient information for rehabilitation units. Web-based modes of patient data collection demonstrate low number of missing data and can therefore improve the quality of data collection from rehabilitation patients. Use of web-based questionnaires considerably reduces administrative costs of data collection in rehabilitation settings compared to traditional pen and paper methods.

    In 2010, our department instituted a nonclinical, administrative rotation in operating room management for anesthesiology residents. Subsequently, we mandated the rotation for all senior anesthesiology residents in 2013. In 2014, under the auspices of the American Society of Anesthesiologists, we developed a web-based module covering the basics of finance, accounting, and operating room management. A multiple-choice test was given to residents at the beginning and end of the rotation, and we compared the mean scores between residents who took the traditional course and residents who took the web-based module. We found no significant difference between the groups of residents, suggesting that the web-based module is as effective as traditional didactics.

  19. Computer-based and web-based radiation safety training

    Energy Technology Data Exchange (ETDEWEB)

    Owen, C., LLNL

    1998-03-01

    The traditional approach to delivering radiation safety training has been to provide a stand-up lecture of the topic, with the possible aid of video, and to repeat the same material periodically. New approaches to meeting training requirements are needed to address the advent of flexible work hours and telecommuting, and to better accommodate individuals learning at their own pace. Computer- based and web-based radiation safety training can provide this alternative. Computer-based and web- based training is an interactive form of learning that the student controls, resulting in enhanced and focused learning at a time most often chosen by the student.

    2012-07-01

    A Web-based reporting system is essential to report incident events anonymously and confidentially. The purpose of this study was to evaluate a Web-based reporting system in Taiwan. User satisfaction and impact of system use were evaluated through a survey answered by 249 nurses. Incident events reported in paper and electronic systems were collected for comparison purposes. Study variables included system user satisfaction, willingness to report, number of reports, severity of the events, and efficiency of the reporting process. Results revealed that senior nurses were less willing to report events, nurses on internal medicine units had higher satisfaction than others, and lowest satisfaction was related to the time it took to file a report. In addition, the Web-based reporting system was used more often than the paper system. The percentages of events reported were significantly higher in the Web-based system in laboratory, environment/device, and incidents occurring in other units, whereas the proportions of reports involving bedsores and dislocation of endotracheal tubes were decreased. Finally, moderate injury event reporting decreased, whereas minor or minimal injury event reporting increased. The study recommends that the data entry process be simplified and the network system be improved to increase user satisfaction and reporting rates.

    Full Text Available Abstract Background Web-based health behavior change programs can reach large groups of disparate participants and thus they provide promise of becoming important public health tools. Data on participant rurality can complement other demographic measures to deepen our understanding of the success of these programs. Specifically, analysis of participant rurality can inform recruitment and social marketing efforts, and facilitate the targeting and tailoring of program content. Rurality analysis can also help evaluate the effectiveness of interventions across population groupings. Methods We describe how the RUCAs (Rural-Urban Commuting Area Codes methodology can be used to examine results from two Randomized Controlled Trials of Web-based tobacco cessation programs: the ChewFree.com project for smokeless tobacco cessation and the Smokers' Health Improvement Program (SHIP project for smoking cessation. Results Using RUCAs methodology helped to highlight the extent to which both Web-based interventions reached a substantial percentage of rural participants. The ChewFree program was found to have more rural participation which is consistent with the greater prevalence of smokeless tobacco use in rural settings as well as ChewFree's multifaceted recruitment program that specifically targeted rural settings. Conclusion Researchers of Web-based health behavior change programs targeted to the US should routinely include RUCAs as a part of analyzing participant demographics. Researchers in other countries should examine rurality indices germane to their country.

    2008-08-01

    As part of the requirement for terminating the licenses of nuclear power plants or other nuclear facilities, license termination plans or decommissioning plans are submitted by the licensee to the U.S. Nuclear Regulatory Commission (NRC) for review and approval. Decommissioning plans generally refer to the decommissioning of nonreactor facilities, while license termination plans specifically refer to the decommissioning of nuclear reactor facilities. To provide a uniform and consistent review of dose modeling aspects of these plans and to address NRC-wide knowledge management issues, the NRC, in 2006, commissioned Argonne National Laboratory to develop a Web-based training course on reviewing radiological dose assessments for license termination. The course, which had first been developed in 2005 to target specific aspects of the review processes for license termination plans and decommissioning plans, evolved from a live classroom course into a Web-based training course in 2006. The objective of the Web-based training course is to train NRC staff members (who have various relevant job functions and are located at headquarters, regional offices, and site locations) to conduct an effective review of dose modeling in accordance with the latest NRC guidance, including NUREG-1757, Volumes 1 and 2. The exact size of the staff population who will receive the training has not yet been accurately determined but will depend on various factors such as the decommissioning activities at the NRC. This Web-based training course is designed to give NRC staff members modern, flexible access to training. To this end, the course is divided into 16 modules: 9 core modules that deal with basic topics, and 7 advanced modules that deal with complex issues or job-specific topics. The core and advanced modules are tailored to various NRC staff members with different job functions. The Web-based system uses the commercially available software Articulate, which incorporates audio, video

    The growing use of internet and online purchasing among young consumers in Malaysia provides a huge prospect in e-commerce market, specifically for B2C segment. In this market, if E-marketers know the web-based factors affecting online buyers' behaviour, and the effect of these factors on behaviour of online consumers, then they can develop their marketing strategies to convert potential customers into active one, while retaining existing online customers. Review of previous studies related to the online purchasing behaviour in B2C market has point out that the conceptualization and empirical validation of the online purchasing behaviour of Information and Communication Technology (ICT) literate users, or ICT professional, in Malaysia has not been clearly addressed. This paper focuses on (i) web-based factors which online buyers (ICT professional) keep in mind while shopping online; and (ii) the effect of web-based factors on online purchasing behaviour. Based on the extensive literature review, a conceptual framework of 24 items of five factors was constructed to determine web-based factors affecting online purchasing behaviour of ICT professional. Analysis of data was performed based on the 310 questionnaires, which were collected using a stratified random sampling method, from ICT undergraduate students in a public university in Malaysia. The Exploratory factor analysis performed showed that five factors affecting online purchase behaviour are Information Quality, Fulfilment/Reliability/Customer Service, Website Design, Quick and Details, and Privacy/Security. The result of Multiple Regression Analysis indicated that Information Quality, Quick and Details, and Privacy/Security affect positively online purchase behaviour. The results provide a usable model for measuring web-based factors affecting buyers' online purchase behaviour in B2C market, as well as for online shopping companies to focus on the factors that will increase customers' online purchase.

    The Web technologies and Web applications have shown similar high growth rate in terms of daily usages and user acceptance. The Web applications have not only penetrated in the traditional domains such as education and business but have also encroached into areas such as politics, social, lifestyle, and culture. The emergence of Web technologies has enabled Web access even to the person on the move through PDAs or mobile phones that are connected using Wi-Fi, HSDPA, or other communication protocols. These two phenomena are the inducement factors toward the need of building Web-based systems as the supporting tools in fulfilling many mundane activities. In doing this, one of the many focuses in research has been to look at the implementation challenges in building Web-based support systems in different types of environment. This chapter describes the implementation issues in building the community learning framework that can be supported on the Web-based platform. The Community of Practice (CoP) has been chosen as the community learning theory to be the case study and analysis as it challenges the creativity of the architectural design of the Web system in order to capture the presence of learning activities. The details of this chapter describe the characteristics of the CoP to understand the inherent intricacies in modeling in the Web-based environment, the evidences of CoP that need to be traced automatically in a slick manner such that the evidence-capturing process is unobtrusive, and the technologies needed to embrace a full adoption of Web-based support system for the community learning framework.

    Advances in computer and Internet technologies have allowed health care providers to develop, use, and test various types of Web-based interventions for their practice and research. Indeed, an increasing number of Web-based interventions have recently been developed and tested in health care fields. Despite the great potential for Web-based interventions to improve practice and research, little is known about the current status of Web-based interventions, especially those related to menopause. To identify the current status of Web-based interventions used in the field of menopause, a literature review was conducted using multiple databases, with the keywords "online," "Internet," "Web," "intervention," and "menopause." Using these keywords, a total of 18 eligible articles were analyzed to identify the current status of Web-based interventions for menopause. Six themes reflecting the current status of Web-based interventions for menopause were identified: (a) there existed few Web-based intervention studies on menopause; (b) Web-based decision support systems were mainly used; (c) there was a lack of detail on the interventions; (d) there was a lack of guidance on the use of Web-based interventions; (e) counselling was frequently combined with Web-based interventions; and (f) the pros and cons were similar to those of Web-based methods in general. Based on these findings, directions for future Web-based interventions for menopause are provided. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Halic, Tansel; Ahn, Woojin; De, Suvranu

    2013-01-01

    This paper presents a technique for performance optimization of multimodal interactive web-based medical simulation. A web-based simulation framework is promising for easy access and wide dissemination of medical simulation. However, the real-time performance of the simulation highly depends on hardware capability on the client side. Providing consistent simulation in different hardware is critical for reliable medical simulation. This paper proposes a non-linear mixed integer programming model to optimize the performance of visualization and physics computation while considering hardware capability and application specific constraints. The optimization model identifies and parameterizes the rendering and computing capabilities of the client hardware using an exploratory proxy code. The parameters are utilized to determine the optimized simulation conditions including texture sizes, mesh sizes and canvas resolution. The test results show that the optimization model not only achieves a desired frame per second but also resolves visual artifacts due to low performance hardware.

    In this paper, we introduce a Web-based visual analytics framework for democratizing advanced visualization and analysis capabilities pertinent to large-scale earth system simulations. We address significant limitations of present climate data analysis tools such as tightly coupled dependencies, ineffi- cient data movements, complex user interfaces, and static visualizations. Our Web-based visual analytics framework removes critical barriers to the widespread accessibility and adoption of advanced scientific techniques. Using distributed connections to back-end diagnostics, we minimize data movements and leverage HPC platforms. We also mitigate system dependency issues by employing a RESTful interface. Our framework embraces the visual analytics paradigm via new visual navigation techniques for hierarchical parameter spaces, multi-scale representations, and interactive spatio-temporal data mining methods that retain details. Although generalizable to other science domains, the current work focuses on improving exploratory analysis of large-scale Community Land Model (CLM) and Community Atmosphere Model (CAM) simulations.

    Web-based learning systems are one of the most interesting topics in the area of the application of computers to education. Collaborative learning, as an important principle in constructivist learning theory, is an important instruction mode for open and distance learning systems. Through collaborative learning, students can greatly improve their creativity, exploration capability, and social cooperation. This paper used an agent-based coordination mechanism to respond to the requirements of an efficient and motivating learning process. This coordination mechanism is based on a Web-based constructivist collaborative learning system, in which students can learn in groups and interact with each other by several kinds of communication modes to achieve their learning objectives efficiently and actively. In this learning system, artificial agents represent an active part in the collaborative learning process; they can partially replace human instructors during the multi-mode interaction of the students.

    Full Text Available We propose a web-based system for organizing the creation and the interaction in multimedia web-based environments that permit the collaboration among artists, audience, curators and publishers. This system uses a threelevel approach for handling security issues in multimedia projects. Especially, it applies authorization, digital certification and watermarking mechanisms on multimedia content. Authorization mechanism controls users operations in multimedia files based on a set of actions imposed on reallife scenarios. Digital certification mechanism ensures the secure content transfers among users and multimedia content server through Web. Digital watermarking mechanism handles copyright-protection and authentication issues that appear in multimedia systems applying a semantically secure watermark. The strength of our system considers multimedia content not as an atomic digital entity, but as a part of a project with a specific workflow that applies watermarking techniques in all its parts.

  9. Cost reduction for web-based data imputation

    KAUST Repository

    Li, Zhixu

    2014-01-01

    Web-based Data Imputation enables the completion of incomplete data sets by retrieving absent field values from the Web. In particular, complete fields can be used as keywords in imputation queries for absent fields. However, due to the ambiguity of these keywords and the data complexity on the Web, different queries may retrieve different answers to the same absent field value. To decide the most probable right answer to each absent filed value, existing method issues quite a few available imputation queries for each absent value, and then vote on deciding the most probable right answer. As a result, we have to issue a large number of imputation queries for filling all absent values in an incomplete data set, which brings a large overhead. In this paper, we work on reducing the cost of Web-based Data Imputation in two aspects: First, we propose a query execution scheme which can secure the most probable right answer to an absent field value by issuing as few imputation queries as possible. Second, we recognize and prune queries that probably will fail to return any answers a priori. Our extensive experimental evaluation shows that our proposed techniques substantially reduce the cost of Web-based Imputation without hurting its high imputation accuracy. © 2014 Springer International Publishing Switzerland.

Enabling the integration of standard Hypertext Markup Language (HTML programming and RDIS tag programming to create a user-friendly “point-and-click” web-based control mechanism. The integration allows the users to send commands to mobile robot over the Internet. Web-based control enables human to extend his action and intelligence to remote locations. Three mechanisms for web-based controls are developed: Manual remote control, continuous operation event and autonomous navigational control. In the manual remote control the user is fully responsible for the robot action and the robot do not use any sophisticated algorithms. The continuous operation event is the extension of the basic movement of a manual remote control mechanism. In the autonomous navigation control, the user has more flexibility to tell the robot to carry out specific tasks. Using this method, mobile robot can be controlled via the web, from any places connected to the network without constructing specific infrastructures for communication.

    Traditional learning needs to be improved since it does not involve active learning among students. Therefore, in the twenty-first century, the development of internet technology in the learning environment has become the main needs of each student. One of the learning environments to meet the needs of the teaching and learning process is a web-based learning environment. This study aims to identify the characteristics of a web-based learning environment that supports students’ learning needs. The study involved 542 students from fifteen faculties in a public higher education institution in Malaysia. A quantitative method was used to collect the data via a questionnaire survey by randomly. The findings indicate that the characteristics of a web-based learning environment that support students’ needs in the process of learning are online discussion forum, lecture notes, assignments, portfolio, and chat. In conclusion, the students overwhelmingly agreed that online discussion forum is the highest requirement because the tool can provide a space for students and teachers to share knowledge and experiences related to teaching and learning.

    Full Text Available The applications of the Internet-based technologies and the concepts of fuzzy expert systems (FES have created new methods for sharing and distributing knowledge. However, there has been a general lack of investigation in the area of web-based fuzzy expert systems. In this paper, the issues associated with the design, development, and use of web-based applications from a standpoint of the benefits and challenges of development and utilization are investigated. The original theory and concepts in conventional FES are reviewed and a knowledge engineering framework for developing such systems is revised. For a human advisor to have a satisfying performance, expertise is a must. In addition, some of advisory rules are subject to change because of domain knowledge update. The human requests may have linguistic or crisp forms and a conventional expert system (ES is not able to overcome the fuzziness in the problem nature. In this research, a Web-based fuzzy expert system for Common Human Advisor (FES-CHA is developed and implemented to be used as a student advisor at the department‘s web portal.

    2016-01-28

    Fatal opioid overdose is a significant public health concern in the United States. One approach to reducing fatalities is expanding overdose response education to broader audiences. This study examined responses to a web-based overdose education tool. The results of 422 anonymous surveys submitted on www.stopoverdose.org were analyzed for participant demographics, knowledge of opioid overdose recognition and response, and knowledge of Washington's Good Samaritan overdose law. Characteristics, knowledge, and planned behavior of respondents with professional versus personal interest in overdose education were compared. Most respondents were age 35 or older (57%) and female (65%). The mean score on the knowledge quiz for overdose recognition and response items was 16.2 out of 18, and 1.5 out of 2 possible points for items concerning the law. Respondents indicating professional interest were significantly more likely to be 35 or older (p = .001) and to have received prior overdose education (p < .001), but less likely to know someone at risk for opioid overdose (p < .001) or report planning to obtain take-home naloxone (p < .001). No significant differences were found in overdose knowledge scores between groups. Online training may be effective among individuals with professional and personal interest in overdose, as general knowledge scores of overdose response were high among both groups. Lower scores reflecting knowledge of the law suggest that the web-based training may not have adequately presented this information. Overall, results suggest that a web-based platform may be a promising approach to basic overdose education.

  4. Leadership emergence over time in short-lived groups: Integrating expectations states theory with temporal person-perception and self-serving bias.

    Kalish, Yuval; Luria, Gil

    2016-10-01

    Research into leadership emergence typically focuses on the attributes of the emergent leader. By considering also the attributes of perceivers and the passage of time, we develop a more complete theory of leadership emergence in short-lived groups. Using expectation states theory as an overarching theoretical framework, and integrating it with the surface- and deep-level diversity literature and with theories of self-serving biases, we examine the predictors of leadership emergence in short timeframes. We conduct a field study in a military assessment boot camp (a pilot study, n = 60; and a main study, n = 89). We use cross-sectional and longitudinal exponential random graph models to analyze data on participants' abilities and on their perceptions of who, in their respective groups, were "leaders." We find that the criteria by which people perceive leadership in others change over time, from easily noticeable attributes to covert leadership-relevant attributes, and that people also rely on leadership-relevant attributes that they possess at high levels to inform their perceptions of leadership in others. The integration of expectation states theory, attribute salience over time and theories of self-serving bias is needed for a full understanding of leadership emergence in groups, because perceivers' own abilities are instrumental in shaping their perceptions of emergent leadership over time. Theoretical and practical implications are discussed. (PsycINFO Database Record

    To identify, catalog, and critically evaluate Web-based resources for critical care education. A multilevel search strategy was utilized. Literature searches were conducted (from 1996 to September 30, 2010) using OVID-MEDLINE, PubMed, and the Cumulative Index to Nursing and Allied Health Literature with the terms "Web-based learning," "computer-assisted instruction," "e-learning," "critical care," "tutorials," "continuing education," "virtual learning," and "Web-based education." The Web sites of relevant critical care organizations (American College of Chest Physicians, American Society of Anesthesiologists, American Thoracic Society, European Society of Intensive Care Medicine, Society of Critical Care Medicine, World Federation of Societies of Intensive and Critical Care Medicine, American Association of Critical Care Nurses, and World Federation of Critical Care Nurses) were reviewed for the availability of e-learning resources. Finally, Internet searches and e-mail queries to critical care medicine fellowship program directors and members of national and international acute/critical care listserves were conducted to 1) identify the use of and 2) review and critique Web-based resources for critical care education. To ensure credibility of Web site information, Web sites were reviewed by three independent reviewers on the basis of the criteria of authority, objectivity, authenticity, accuracy, timeliness, relevance, and efficiency in conjunction with suggested formats for evaluating Web sites in the medical literature. Literature searches using OVID-MEDLINE, PubMed, and the Cumulative Index to Nursing and Allied Health Literature resulted in >250 citations. Those pertinent to critical care provide examples of the integration of e-learning techniques, the development of specific resources, reports of the use of types of e-learning, including interactive tutorials, case studies, and simulation, and reports of student or learner satisfaction, among other general

    Recent years have seen massive, distributed datasets become the norm in neuroimaging research, and the methodologies used to analyze them have, in response, become more collaborative and exploratory. Tools and infrastructure are continuously being developed and deployed to facilitate research in this context: grid computation platforms to process the data, distributed data stores to house and share them, high-speed networks to move them around and collaborative, often web-based, platforms to provide access to and sometimes manage the entire system. BrainBrowser is a lightweight, high-performance JavaScript visualization library built to provide easy-to-use, powerful, on-demand visualization of remote datasets in this new research environment. BrainBrowser leverages modern web technologies, such as WebGL, HTML5 and Web Workers, to visualize 3D surface and volumetric neuroimaging data in any modern web browser without requiring any browser plugins. It is thus trivial to integrate BrainBrowser into any web-based platform. BrainBrowser is simple enough to produce a basic web-based visualization in a few lines of code, while at the same time being robust enough to create full-featured visualization applications. BrainBrowser can dynamically load the data required for a given visualization, so no network bandwidth needs to be waisted on data that will not be used. BrainBrowser's integration into the standardized web platform also allows users to consider using 3D data visualization in novel ways, such as for data distribution, data sharing and dynamic online publications. BrainBrowser is already being used in two major online platforms, CBRAIN and LORIS, and has been used to make the 1TB MACACC dataset openly accessible.

    Full Text Available Abstract Background There is great concern within health surveillance, on how to grapple with environmental degradation, rapid urbanization, population mobility and growth. The Internet has emerged as an efficient way to share health information, enabling users to access and understand data at their fingertips. Increasingly complex problems in the health field require increasingly sophisticated computer software, distributed computing power, and standardized data sharing. To address this need, Web-based mapping is now emerging as an important tool to enable health practitioners, policy makers, and the public to understand spatial health risks, population health trends and vulnerabilities. Today several web-based health applications generate dynamic maps; however, for people to fully interpret the maps they need data source description and the method used in the data analysis or statistical modeling. For the representation of health information through Web-mapping applications, there still lacks a standard format to accommodate all fixed (such as location and variable (such as age, gender, health outcome, etc indicators in the representation of health information. Furthermore, net-centric computing has not been adequately applied to support flexible health data processing and mapping online. Results The authors of this study designed a HEalth Representation XML (HERXML schema that consists of the semantic (e.g., health activity description, the data sources description, the statistical methodology used for analysis, geometric, and cartographical representations of health data. A case study has been carried on the development of web application and services within the Canadian Geospatial Data Infrastructure (CGDI framework for community health programs of the New Brunswick Lung Association. This study facilitated the online processing, mapping and sharing of health information, with the use of HERXML and Open Geospatial Consortium (OGC services

    There is accumulating evidence that reaction times (RTs) can be used to detect recognition of critical (e.g., crime) information. A limitation of this research base is its reliance upon small samples (average n = 24), and indications of publication bias. To advance RT-based memory detection, we report upon the development of the first web-based memory detection test. Participants in this research (Study1: n = 255; Study2: n = 262) tried to hide 2 high salient (birthday, country of origin) and 2 low salient (favourite colour, favourite animal) autobiographical details. RTs allowed to detect concealed autobiographical information, and this, as predicted, more successfully so than error rates, and for high salient than for low salient items. While much remains to be learned, memory detection 2.0 seems to offer an interesting new platform to efficiently and validly conduct RT-based memory detection research.

    Full Text Available In the traditional deductive approach in teaching any engineering topic, teachers would first expose students to the derivation of the equations that govern the behavior of a physical system and then demonstrate the use of equations through a limited number of textbook examples. This methodology, however, is rarely adequate to unmask the cause-effect and quantitative relationships between the system variables that the equations embody. Web-based simulation, which is the integration of simulation and internet technologies, has the potential to enhance the learning experience by offering an interactive and easily accessible platform for quick and effortless experimentation with physical phenomena.This paper presents the design and development of a web-based platform for teaching basic food engineering phenomena to food technology students. The platform contains a variety of modules (“virtual experiments” covering the topics of mass and energy balances, fluid mechanics and heat transfer. In this paper, the design and development of three modules for mass balances and heat transfer is presented. Each webpage representing an educational module has the following features: visualization of the studied phenomenon through graphs, charts or videos, computation through a mathematical model and experimentation.  The student is allowed to edit key parameters of the phenomenon and observe the effect of these changes on the outputs. Experimentation can be done in a free or guided fashion with a set of prefabricated examples that students can run and self-test their knowledge by answering multiple-choice questions.

    2007-01-01

    Advanced Tool Integration Environment (ATIE) is the name of both a software system and a Web-based environment created by the system for maintaining an archive of legacy software and expertise involved in developing the legacy software. ATIE can also be used in modifying legacy software and developing new software. The information that can be encapsulated in ATIE includes experts documentation, input and output data of tests cases, source code, and compilation scripts. All of this information is available within a common environment and retained in a database for ease of access and recovery by use of powerful search engines. ATIE also accommodates the embedment of supporting software that users require for their work, and even enables access to supporting commercial-off-the-shelf (COTS) software within the flow of the experts work. The flow of work can be captured by saving the sequence of computer programs that the expert uses. A user gains access to ATIE via a Web browser. A modern Web-based graphical user interface promotes efficiency in the retrieval, execution, and modification of legacy code. Thus, ATIE saves time and money in the support of new and pre-existing programs.

    2017-07-01

    To facilitate progress in climate change adaptation policy and practice, it is important not only to ensure the production of accurate, comprehensive and relevant information, but also the easy, timely and affordable access to it. This can contribute to better-informed decisions and improve the design and implementation of adaptation policies and other relevant initiatives. Web-based platforms can play an important role in communicating and distributing data, information and knowledge that become constantly available, reaching out to a large group of potential users. Indeed in the last decade there has been an extensive increase in the number of platforms developed for this purpose in many fields including climate change adaptation. This short paper concentrates on the web-based adaptation platforms developed in Europe. It provides an overview of the recently emerged landscape, examines the basic characteristics of a set of platforms that operate at national, transnational and European level, and discusses some of the key challenges related to their development, maintenance and overall management. Findings presented in this short paper are discussed in greater detailed in the Technical Report of the European Environment Agency Overview of climate change adaptation platforms in Europe.

    Full Text Available The rapid advance of Information Communication Technology [ICT] has enabled Higher Education Institutions to reach out and educate students transcending the barriers of time and space. This technology supports structured, web-based learning activities, and provides diverse multilingual and multicultural settings and also facilities for self assessment. Structured collaboration, in the conventionaleducation system, has proven itself a successful and powerful learning method. Online learners do not enjoy the same collaborative benefits as face-to-face learners because the technology provides no guidance or direction during the online discussion sessions. This paper presents a Web Based Learning Environment [WBLE] from the perspective of social computing to bring collaborative learning benefits to online learners. The paper also highlights how the deployment of social computing tools can support the creation of an open and socially shared information space for better collaboration among the learners. With Social Network Analysis [SNA] techniques, collaboration among twenty learners is explored and metrics such as in-degree, out-degree and Betweenness and collaborative network mapping are presented.

    2014-11-01

    In engineering courses with very specific learning objectives, such as fluid mechanics and thermodynamics, it is conventional to reinforce concepts and principles with problem-solving assignments and to measure success in problem solving as an indicator of student achievement. While the modern-day ease of copying and searching for online solutions can undermine the value of traditional assignments, web-based technologies also provide opportunities to generate individualized well-posed problems with an infinite number of different combinations of initial/final/boundary conditions, so that the probability of any two students being assigned identical problems in a course is vanishingly small. Such problems can be designed and programmed to be: single or multiple-step, self-grading, allow students single or multiple attempts; provide feedback when incorrect; selectable according to difficulty; incorporated within gaming packages; etc. In this talk, we discuss the use of a homework/exam generating program of this kind in a single-semester course, within a web-based client-server system that ensures secure operation.

    Full Text Available The population of students all over the world is growing without a proportionate increase in teaching/learning resources/infrastructure. There is also much quest for learning in an environment that provides equal opportunities to all learners. The need to provide an equal opportunity learning environment that will hitherto improve the system of education globally has therefore become imperative. Based on our findings, a mathematical model Web-based Virtual Classroom system (WebVCS was developed to provide a viable medium through which sound education can be offered in tertiary institutions that can carter for varieties of learners irrespective of their abilities, dispositions and geographical locations. Our system model is developed based on active learning approach that adopts blended learning theory (Constructivist-Cognivist learning approach, incorporating e-pedagogy that supports collaboration among participants in the web-based Virtual learning environment. The key objects used in creating the WebVCS model are: Courses, Students, Instructors and Learning performances. Our system model sets a framework for developers of virtual classrooms and successful implementation of the model leads to students learning by interacting with their peers resulting in the construction of knowledge.

    Full Text Available It might be said that attitudes impact success directly in web-based teaching and timely and appropriate fulfillment of learners’ expectations bear utmost significance for their success. From this perspective a properly designed web supported teaching application can provide positive contribution as well to learners’ attitudes towards web supported teaching and internet. Based on this premise, the objective of present research is to explore the effects of different interaction types in web-based teaching setting on the attitudes of learners towards web-based teaching and internet. An experimental pattern with pretest-posttest control group was used in the study. Study group of research consists of 77 students. Research data have been compiled via Attitude towards Internet Scale (α=0,77 and Attitude towards Web-based Learning Scale (α=0,86. In one of the experimental groups, synchronous web-based training interaction and in the other group asynchronous web-based training interaction and in the control group learner-content only interaction has been provided. In data analysis; standard deviation, arithmetical means, one-way variance analysis and LSD tests have been employed. As a result: Web-based training applications with synchronous interaction, compared to web-based training application with learner-content only interaction, have significantly higher contribution on learners’ attitudes towards web-based teaching. In Web-based teaching settings different types of interaction have no effect on learners’ attitudes towards internet which may be attributed to the fact that learners’ attitudes towards internet were already in quite high levels prior to the procedure.

    2000-01-01

    Virtual Reality offers great potential for surgical training--yet is typically limited by the dedicated and expensive equipment required. Web-based VR has the potential to offer a much cheaper alternative, in which simulations of fundamental techniques are downloaded from a server to run within a web browser. The equipment requirement is modest--an Internet-connected PC or small workstation--and the simulation can be accessed worldwide. In a collaboration between computer scientists and neurosurgeons, we have studied the use of web-based VR to train neurosurgeons in Percutaneous Rhizotomy--a treatment for the intractable facial pain which occurs in trigeminal neuralgia. This involves the insertion of a needle so as to puncture the foramen ovale, and lesion the nerve. Our simulation uses VRML to provide a 3D visualization environment, but the work immediately exposes a key limitation of VRML for surgical simulation. VRML does not support collision detection between objects--only between viewpoint and object. Thus collision between needle and skull cannot be detected and fed back to the trainee. We have developed a novel solution in which the training simulation has linked views: a normal view, plus a view as seen from the tip of the needle. Collision detection is captured in the needle view, and fed back to the viewer. A happy consequence of this approach has been the chance to aid the trainee with this additional view from needle tip, which helps locate the foramen ovale. The technology to achieve this is Java software communicating with the VRML worlds through the External Authoring Interface (EAI). The training simulator is available on the Web, with accompanying tutorial on its use. A major advantage of web-based VR is that the techniques generalize to a whole range of surgical simulations. Thus we have been able to use exactly the same approach as described above for neurosurgery, to develop a shoulder arthroscopy simulator--where again collision detection, and

    In this era of shrinking federal budgets in the USA we need to dramatically improve our efficiency in the spacecraft engineering design process. We have come up with a method which captures much of the experts' expertise in a dataflow design graph: Seamlessly connectable set of local and remote design tools; Seamlessly connectable web based design tools; and Web browser interface to the developing spacecraft design. We have recently completed our first web browser interface and demonstrated its utility in the design of an aeroshell using design tools located at web sites at three NASA facilities. Multiple design engineers and managers are now able to interrogate the design engine simultaneously and find out what the design looks like at any point in the design cycle, what its parameters are, and how it reacts to adverse space environments.

    1998-01-01

    In today's competitive environment, both industry and government agencies are under pressure to reduce the time and cost of multidisciplinary design projects. New tools have been introduced to assist in this process by facilitating the integration of and communication among diverse disciplinary codes. One such tool, a framework for multidisciplinary computational environments, is defined as a hardware and software architecture that enables integration, execution, and communication among diverse disciplinary processes. An examination of current frameworks reveals weaknesses in various areas, such as sequencing, displaying, monitoring, and controlling the design process. The objective of this research is to explore how Web technology, integrated with an existing framework, can improve these areas of weakness. This paper describes a Web-based system that optimizes and controls the execution sequence of design processes; and monitors the project status and results. The three-stage evolution of the system with increasingly complex problems demonstrates the feasibility of this approach.

    The paper addresses Medical Hand Drawing Management System architecture and implementation. In the system, we developed four modules: hand drawing management module; patient medical records query module; hand drawing editing and upload module; hand drawing query module. The system adapts windows-based applications and encompasses web pages by ASP.NET hosting mechanism under web services platforms. The hand drawings implemented as files are stored in a FTP server. The file names with associated data, e.g. patient identification, drawing physician, access rights, etc. are reposited in a database. The modules can be conveniently embedded, integrated into any system. Therefore, the system possesses the hand drawing features to support daily medical operations, effectively improve healthcare qualities as well. Moreover, the system includes the printing capability to achieve a complete, computerized medical document process. In summary, the system allows web-based applications to facilitate the graphic processes for healthcare operations.

    Biomedical ontologies are often very large and complex. Only a subset of the ontology may be needed for a specified application or community. For ontology end users, it is desirable to have community-based labels rather than the labels generated by ontology developers. Ontodog is a web-based system that can generate an ontology subset based on Excel input, and support generation of an ontology community view, which is defined as the whole or a subset of the source ontology with user-specified annotations including user-preferred labels. Ontodog allows users to easily generate community views with minimal ontology knowledge and no programming skills or installation required. Currently >100 ontologies including all OBO Foundry ontologies are available to generate the views based on user needs. We demonstrate the application of Ontodog for the generation of community views using the Ontology for Biomedical Investigations as the source ontology.

    2007-06-01

    This paper introduced a SQL level approach to resolve global spatial query in Web based heterogeneous distributed spatial database environment. The main prohibit of this SQL level approach was its widespread compatibility and standardization. Firstly, a SQL based Equivalent Distributed Program (EDP) was introduced to express distributed spatial processing transactions. Then global resource directories for virtual global view describing were discussed to organize information that resolving need. The contents of global resource directories included data storage directory, hosts directory and working status directory. With these mechanisms, relational algebra expression equivalence principles were utilized to resolve global spatial queries to EDPs. Finally, several samples were presented to show the process of resolving. This approach was suitable to all sorts of distributed computing environments either centralized such as CORBA or decentralized such as P2P computing platforms.

    Full Text Available Pre- and postcourse assessment has become a very important tool for education research in physics and other areas. The web offers an attractive alternative to in-class paper administration, but concerns about web-based administration include reliability due to changes in medium, student compliance rates, and test security, both question leakage and utilization of web resources. An investigation was carried out in introductory astronomy courses comparing pre- and postcourse administration of assessments using the web and on paper. Overall no difference was seen in performance due to the medium. Compliance rates fluctuated greatly, and factors that seemed to produce higher rates are identified. Notably, email reminders increased compliance by 20%. Most of the 559 students complied with requests to not copy, print, or save questions nor use web resources; about 1% did copy some question text and around 2% frequently used other windows or applications while completing the assessment.

    2016-02-01

    Full Text Available The use of the internet as a medium of dissemination of information to stakeholders is increasingly gaining grounds. This study extends existing literature on web disclosures by investigating the characteristics that predict the extent of web-based disclosures. In this study, corporate websites of top Nigerian firms are used as sources of data, while a regression analysis is employed to examine the extent of prediction. Results indicate that the firm size and industry type are significant determinants of web disclosures. However, other firm traits such as ownership dispersion and financial performance do not significantly explain the extent of internet disclosures. The study recommends that a regulatory template for corporate web disclosures be put in place by government regardless of the size or industry classification of the firm. This is with a view to considerably reduce agency conflicts arising from information asymmetry in publicly listed firms in Nigeria.

    The Compact Muon Solenoid (CMS) is a large and complex general purpose experiment at the CERN Large Hadron Collider (LHC), built and maintained by many collaborators from around the world. Efficient operation of the detector requires widespread and timely access to a broad range of monitoring and status information. To this end the Web Based Monitoring (WBM) system was developed to present data to users located anywhere from many underlying heterogeneous sources, from real time messaging systems to relational databases. This system provides the power to combine and correlate data in both graphical and tabular formats of interest to the experimenters, including data such as beam conditions, luminosity, trigger rates, detector conditions, and many others, allowing for flexibility on the user side. This paper describes the WBM system architecture and describes how the system was used during the first major data taking run of the LHC.

    Brain volume calculations are crucial in modern medical research, especially in the study of neurodevelopmental disorders. In this paper, we present an algorithm for calculating two classifications of brain volume, total brain volume (TBV) and intracranial volume (ICV). Our algorithm takes MRI data as input, performs several preprocessing and intermediate steps, and then returns each of the two calculated volumes. To simplify this process and make our algorithm publicly accessible to anyone, we have created a web-based interface that allows users to upload their own MRI data and calculate the TBV and ICV for the given data. This interface provides a simple and efficient method for calculating these two classifications of brain volume, and it also removes the need for the user to download or install any applications.

    It is often cumbersome to reuse or share web-based materials developed for a particular course. The LON-CAPA project based at Michigan State University is being supported by an Information Technology Research grant from the National Science Foundation (as well as other means) to investigate means of improving resource sharing and reuseability. The LON-CAPA (Learning Online Network with Computer-Assisted Personalized Approach) combines the CAPA assessment engine (homework, quizzes, exams) with a full course delivery system. The system is being piloted at Michigan State and several other institutions. The Ohio University Department of Physics and Astronomy will begin using the system beginning Winter 2002. I will discuss the basic concepts and capabilities of the LON-CAPA system. Background information on the system can be found at the URL: http://www.lon-capa.org.

    The Compact Muon Solenoid is a large a complex general purpose experiment at the CERN Large Hadron Collider (LHC), built and maintained by many collaborators from around the world. Efficient operation of the detector requires widespread and timely access to a broad range of monitoring and status information. To the end the Web Based Monitoring (WBM) system was developed to present data to users located anywhere from many underlying heterogeneous sources, from real time messaging systems to relational databases. This system provides the power to combine and correlate data in both graphical and tabular formats of interest to the experimenters, including data such as beam conditions, luminosity, trigger rates, detector conditions, and many others, allowing for flexibility on the user’s side. This paper describes the WBM system architecture and describes how the system has been used from the beginning of data taking until now (Run1 and Run 2).

    Moynihan, Gary P.

    2004-02-01

    Pollution prevention is a complex task. Many small foundries lack the in-house expertise to perform these tasks. Expert systems are a type of computer information system that incorporates artificial intelligence. As noted in the literature, they provide a means of automating specialized expertise. This approach may be further leveraged by implementing the expert system on the internet (or world-wide web). This will allow distribution of the expertise to a variety of geographically-dispersed foundries. The purpose of this research is to develop a prototype web-based expert system to support pollution prevention for the foundry industry. The prototype system identifies potential emissions for a specified process, and also provides recommendations for the prevention of these contaminants. The system is viewed as an initial step toward assisting the foundry industry in better meeting government pollution regulations, as well as improving operating efficiencies within these companies.

    2013-01-01

    Cathode Strip Chambers (CSC) are gas detectors in Compact Muon Solenoid (CMS) experiment that can determine paths of muons accurately. The data taken from the chambers are digital data and usually saved to files. Sometimes we need graphical representation of the data to analyze some files. A software had been developed to comply the needs, but it had limitations, didn't meet some specifications, and few major drawbacks. Hence, a new version of the software is developed to overcome its limitations, drawbacks, and also to meet the all specifications. Besides that, there are also additional features added to the new version software to help users analyze data. The new version software is a web-based application, which is different from the desktop-based application of the old version software. In the end, response in CSC Online Systems weekly meeting (12/08/13) for this application was positive, so this application should be maintained and developed in future.

    Full Text Available Pre- and postcourse assessment has become a very important tool for education research in physics and other areas. The web offers an attractive alternative to in-class paper administration, but concerns about web-based administration include reliability due to changes in medium, student compliance rates, and test security, both question leakage and utilization of web resources. An investigation was carried out in introductory astronomy courses comparing pre- and postcourse administration of assessments using the web and on paper. Overall no difference was seen in performance due to the medium. Compliance rates fluctuated greatly, and factors that seemed to produce higher rates are identified. Notably, email reminders increased compliance by 20%. Most of the 559 students complied with requests to not copy, print, or save questions nor use web resources; about 1% did copy some question text and around 2% frequently used other windows or applications while completing the assessment.

    Web-based-remote (WBR) intervention is a new approach that incorporates smart control technology and modern medicine to monitor patient compliance. It is based on computer control and communication technology. This study is to explore the benefits of WBR psychological intervention for cancer treatment. 128 patients diagnosed with cancer by Pathology Department of our hospital between 1 February 2013 and 1 August 2013 were included. Patients were randomly assigned to intervention and control group (n = 64). The Questionnaire-Core 30 (QLQ-C30) was used for the survey. Intervention group received WBR psychological intervention in addition to regular clinical follow-up care. Control group only received regular clinical follow-up care. The QLQ-C30 score was significantly better in the intervention group than the control group when the intervention and control groups were followed for three months. In conclusion, WBR psychological intervention substantially improves the quality of life in patients during cancer treatment.

    Full Text Available Web Based Instruction (WBI possesses great potential for delivering e-learning solutions into Lower Economically Disadvantaged Countries (LEDCs and organizations with virtual networks of employees spread across the globe. However, these e-learning solutions are not without cross-cultural challenges. In order to adequately utilize these resources, it is imperative that developers and organizations understand how to address differences in norms, preferences and values of culturally diverse individuals when designing WBI. When instruction does not effectively address student needs, users can be distracted, or even discouraged, from completing instruction and quite possibly reject the technology through which the instruction is delivered. The purpose of this paper is to present an examination of cross cultural challenges in implementing WBI, through a discussion of Hofstede’s (1980 cultural dimensions, cultural technology perceptions, language barriers and user needs. The paper concludes with a discussion the implications of WBI and future trends in WBI design.

    Full Text Available The availability of geospatial data sets is exploding. New satellites, aerial platforms, video feeds, global positioning system tagged digital photos, and traditional GIS information are dramatically increasing across the globe. These raw materials need to be dynamically processed, combined and correlated to generate value added information products to answer a wide range of questions. This article provides an overview of OMAR web based geospatial processing. OMAR is part of the Open Source Software Image Map project under the Open Source Geospatial Foundation. The primary contributors of OSSIM make their livings by providing professional services to US Government agencies and programs. OMAR provides one example that open source software solutions are increasingly being deployed in US government agencies. We will also summarize the capabilities of OMAR and its plans for near term development.

  4. Web bases for sl(3) are not dual canonical

    1997-01-01

    We compare two natural bases for the invariant space of a tensor product of irreducible representations of A2, or sl(3). One basis is the web basis, defined from a skein theory called the combinatorial A2 spider. The other basis is the dual canonical basis, the dual of the basis defined by Lusztig and Kashiwara. For sl(2) or A1, the web bases have been discovered many times and were recently shown to be dual canonical by Frenkel and Khovanov. We prove that for sl(3), the two bases eventually diverge even though they agree in many small cases. The first disagreement comes in the invariant space Inv((V^+ tensor V^+ tensor V^- tensor V^-)^{tensor 3)), where V^+ and V^- are the two 3-dimensional representations of sl(3); if the tensor factors are listed in the indicated order, only 511 of the 512 invariant basis vectors coincide.

    2013-04-01

    The present paper describes the design and the deployment of an instrumentation system enabling the energy monitoring of a building in a smart-grid context. The system is based on a network of wireless low power IPv6 sensors. Ambient temperature and electrical power for heating are measured. The management, storage, visualisation and treatment of the data is done through a web-based application that can be deployed as an online web service. The same web-based framework enables the acquisition of distant measured data such as those coming from a nearby weather station. On-site sensor and weather station data are then adequately treated based on inverse identification methods. The algorithms aim at determining the parameters of a numerical model suitable for a short-time horizon prediction of indoor climate. The model is based on standard multi-zone modelling assumptions and takes into account solar, airflow and conductive transfers. It was specially designed to render accurately inertia effects that are used in a demand-response strategy. All the hardware or software technologies that are used in the system are open and low cost so that they comply with the constraints of on-site deployment in buildings. The measured data as well as the model predictions can be accessed ubiquously through the web. This feature enables to consider a wide range of energy management applications at the disctrict, city or national level. The entire system has been deployed and tested in an experimental office building in Angers, France. It demonstrates the potential of ICT technologies to enable remotely controlled monitoring and surveillance in real time.

    1999-01-01

    Full Text Available This paper presents a project of Web-based Distance Learning support system. The system has been built based on the Internet and World Wide Web facility. The system could be accessed with a web browser which is directed to a certain web server address so that students can do learning process just like in the real situation, such as student admissions, taking course materials, syllabus, assignments, students grades, class discussions through web, and doing online quizzes. Students could also join collaboration works by giving opinions, feedback and student produced paper/web which can be shared to the entire learning community. Therefore, it will build a collaborative learning environment where lectures together with students make constructive knowledge databases for entire learning community. This system has been developed based on Active Server Pages (ASP technology from Microsoft which is embedded in a web server. Web pages reside in a web server which is connected to an SQL Database Server. Database server is used to store structured data such as lectures/students personal information, course lists, syllabus and its descriptions, announcement texts from lecturers, commentaries for discussion forum, student's study evaluations, scores for each assignment, quizzes for each course, assignments text from lectures, assignments which are collected by students and students contribution/materials. This system has been maintained by an administrator for maintaining and developing web pages using HTML. The administrator also does ASP scripts programming to convert web pages into active server pages. Lectures and students could contribute some course materials and share their ideas through their web browser. This web-based collaborative learning system gives the students more active role in the information gathering and learning process, making the distance students feel part of a learning community, therefore increasing motivation, comprehension and

    Ethical leadership is important for developing ethical healthcare practice. However, there is little research-based knowledge on how to stimulate and educate for ethical leadership. The aim was to develop and investigate the feasibility of a 6-week web-based, ethical leadership educational programme and learn from participants' experience. Training programme and research design: A training programme was developed consisting of (1) a practice part, where the participating middle managers developed and ran an ethics project in their own departments aiming at enhancing the ethical mindfulness of the organizational culture, and (2) a web-based reflection part, including online reflections and coaching while executing the ethics project. Focus group interviews were used to explore the participants' experiences with and the feasibility of the training. Participants and research context: Nine middle managers were recruited from a part-time master's programme in leadership in Oslo, Norway. The research context was the participating leaders' work situation during the 6 weeks of training. Ethical considerations: Participation was voluntary, data anonymized and the confidentiality of the participating leaders/students and their institutions maintained. No patient or medical information was involved. Eight of the nine recruited leaders completed the programme. They evaluated the training programme as efficient and supportive, with the written, situational feedback/coaching as the most important element, enhancing reflection and motivation, counteracting a feeling of loneliness and promoting the execution of change. The findings seem consistent with the basic assumptions behind the educational design, based partly on e-health research, feedback studies and organizational ethics methodology, partly on theories on workplace learning, reflection, recognition and motivation. The training programme seems feasible. It should be adjusted according to participants' proposals and tested

    BACKGROUND To meet the demands of delivering the Foundation programme across a geographically diverse country, two web based systems (ePortfolio and eLearning) were developed to promote accessibility to training material and assessment tools on standardised platforms. This study evaluated the use of both tools throughout an entire academic year. METHODS All Scottish Foundation trainees' online learning and assessment data in 2007/08 were analysed, providing a national breakdown of post specialty, completion rates of mandatory assessments (including summary analysis of anonymised scores), and trainees' use of non-mandatory learning tools. Independent verification of competence data was sought from Deaneries. RESULTS There were high levels of engagement with both the ePortfolio (75-97% assessment completion) and eLearning systems (89-98% induction course completion), and the majority of trainees completed all required elements. There was extensive use of ePortfolio beyond mandatory levels for recording of learning events, including almost 20 000 personal learning records submitted by second year trainees. There was evidence that ePortfolio was used to record achievement of clinical competence rather than to track improvements towards competence (median workplace based assessment scores were 'high' or 'very high'). Online learning modules received positive feedback and its flexible format suited the trainees' working environment. External verification of formal assessment data revealed good correlation with locally stored outcomes, both indicating approximately 99% programme completion rates. CONCLUSIONS Core components of the Foundation programme have been delivered successfully to thousands of trainees across Scotland using web based systems to deliver and support education and assessment. There is great potential for further exploration of this carefully managed, rich dataset at individual, regional, and national levels to inform the future of medical education.

    2014-12-01

    There are many Earth science projects and data systems being developed at the Jet Propulsion Laboratory, California Institute of Technology (JPL) that require the use of Geographic Information Systems (GIS). Three in particular are: (1) the JPL Airborne Snow Observatory (ASO) that measures the amount of water being generated from snow melt in mountains; (2) the Regional Climate Model Evaluation System (RCMES) that compares climate model outputs with remote sensing datasets in the context of model evaluation and the Intergovernmental Panel on Climate Change and for the U.S. National Climate Assessment and; (3) the JPL Snow Server that produces a snow and ice climatology for the Western US and Alaska, for the U.S. National Climate Assessment. Each of these three examples and all other earth science projects are strongly in need of having GIS and geoprocessing capabilities to process, visualize, manage and store GeoSpatial data. Beside some open source GIS libraries and some software like ArcGIS there are comparatively few open source, web-based and easy to use application that are capable of doing GIS processing and visualization. To address this, we present GISCube, an open source web-based GIS application that can store, visualize and process GIS and GeoSpatial data. GISCube is powered by Geothon, an open source python GIS cookbook. Geothon has a variety of Geoprocessing tools such data conversion, processing, spatial analysis and data management tools. GISCube has the capability of supporting a variety of well known GIS data formats in both vector and raster formats, and the system is being expanded to support NASA's and scientific data formats such as netCDF and HDF files. In this talk, we demonstrate how Earth science and other projects can benefit by using GISCube and Geothon, its current goals and our future work in the area.

    Full Text Available

    Can the three concepts of Neutralization Techniques, Moral Disengagement, and Secondary Self-Serving Cognitive Distortions be conceived theoretically and empirically
    as capturing the same cognitive processes and thus be measured with one single scale of Moral Neutralization? First, we show how the different approaches overlap conceptually. Second, in Study 1, we verify that four scales derived from the three conceptions of Moral Neutralization are correlated in such a way that they can be conceived as measuring the same phenomenon. Third, building on the results of Study 1, we derive a unified scale of Moral Neutralization which specifically focuses on the neutralization of aggression and test it in a large general population sample of preadolescents (Study 2. Confirmatory factor analyses suggest a good internal consistency and acceptable cross-gender factorial invariance. Correlation analyses with related behavioral and cognitive constructs corroborate the scale’s criterion and convergent validity. In the final section we present a possible integration of Moral Neutralization in a broader framework of crime causation.

    Acceptance and Commitment Therapy (ACT) has been demonstrated to be effective in reducing depressive symptoms. However, little is known how and for whom therapeutic change occurs, specifically in web-based interventions. This study focuses on the mediators, moderators and predictors of change during a web-based ACT intervention. Data from 236 adults from the general population with mild to moderate depressive symptoms, randomized to either web-based ACT (n = 82) or one of two control conditions (web-based Expressive Writing (EW; n = 67) and a waiting list (n = 87)), were analysed. Single and multiple mediation analyses, and exploratory linear regression analyses were performed using PROCESS and linear regression analyses, to examine mediators, moderators and predictors on pre- to post- and follow-up treatment change of depressive symptoms. The treatment effect of ACT versus the waiting list was mediated by psychological flexibility and two mindfulness facets. The treatment effect of ACT versus EW was not significantly mediated. The moderator analyses demonstrated that the effects of web-based ACT did not vary according to baseline patient characteristics when compared to both control groups. However, higher baseline depressive symptoms and positive mental health and lower baseline anxiety were identified as predictors of outcome across all conditions. Similar results are found for follow-up. The findings of this study corroborate the evidence that psychological flexibility and mindfulness are distinct process mechanisms that mediate the effects of web-based ACT intervention. The results indicate that there are no restrictions to the allocation of web-based ACT intervention and that web-based ACT can work for different subpopulations. Netherlands Trial Register NTR2736 .

    2012-04-01

    As part of the research done in the European project SafeLand "Living with landslide risk in Europe: Assessment, effects of global change, and risk management strategies", a compendium of structural and non-structural mitigation measures for different landslide types in Europe was prepared, and the measures were assembled into a web-based "toolbox". Emphasis was placed on providing a rational and flexible framework applicable to existing and future mitigation measures. The purpose of web-based toolbox is to assist decision-making and to guide the user in the choice of the most appropriate mitigation measures. The mitigation measures were classified into three categories, describing whether the mitigation measures addressed the landslide hazard, the vulnerability or the elements at risk themselves. The measures considered include structural measures reducing hazard and non-structural mitigation measures, reducing either the hazard or the consequences (or vulnerability and exposure of elements at risk). The structural measures include surface protection and control of surface erosion; measures modifying the slope geometry and/or mass distribution; measures modifying surface water regime - surface drainage; measures mo¬difying groundwater regime - deep drainage; measured modifying the mechanical charac¬teristics of unstable mass; transfer of loads to more competent strata; retaining structures (to modify slope geometry and/or to transfer stress to compe¬tent layer); deviating the path of landslide debris; dissipating the energy of debris flows; and arresting and containing landslide debris or rock fall. The non-structural mitigation measures, reducing either the hazard or the consequences: early warning systems; restricting or discouraging construction activities; increasing resistance or coping capacity of elements at risk; relocation of elements at risk; sharing of risk through insurance. The measures are described in the toolbox with fact sheets providing a

    Keyword vocabularies are used to tag and to identify data of science data repositories. Such vocabularies consist of controlled terms and the appropriate concepts, such as GCMD1 keywords or the ESPAS2 keyword ontology. The Semantic Web-based mash-up of domain-specific, cross- or even trans-domain vocabularies provides unique capabilities in the network of appropriate data resources. Based on a collaboration between GFZ3, the FHP4, the WDC for Geomagnetism5 and the NICT6 we developed the concept of a vocabulary broker for inter- and trans-disciplinary data detection and integration. Our prototype of the Semantic Web-based vocabulary broker uses OSF7 for the mash-up of geo and space research vocabularies, such as GCMD keywords, ESPAS keyword ontology and SPASE8 keyword vocabulary. The vocabulary broker starts the search with "free" keywords or terms of a specific vocabulary scheme. The vocabulary broker almost automatically connects the different science data repositories which are tagged by terms of the aforementioned vocabularies. Therefore the mash-up of the SKOS9 based vocabularies with appropriate metadata from different domains can be realized by addressing LOD10 resources or virtual SPARQL11 endpoints which maps relational structures into the RDF format12. In order to demonstrate such a mash-up approach in real life, we installed and use a D2RQ13 server for the integration of IUGONET14 data which are managed by a relational database. The OSF based vocabulary broker and the D2RQ platform are installed at virtual LINUX machines at the Kyoto University. The vocabulary broker meets the standard of a main component of the WDS15 knowledge network.

  14. Web-based Video Annotation and its Applications

    Science.gov (United States)

    Yamamoto, Daisuke; Nagao, Katashi

    In this paper, we developed a Web-based video annotation system, named iVAS (intelligent Video Annotation Server). Audiences can associate any video content on the Internet with annotations. The system analyzes video content in order to acquire cut/shot information and color histograms. And it also automatically generates a Web page for editing annotations. Then, audiences can create annotation data by two methods. The first one helps the users to create text data such as person/object names, scene descriptions, and comments interactively. The second method facilitates the users associating any video fragments with their subjective impression by just clicking a mouse button. The generated annotation data are accumulated and managed by an XML database connected with iVAS. We also developed some application systems based on annotations such as video retrieval, video simplification, and video-content-based community support. One of the major advantages of our approach is easy integration of hand-coded and automatically-generated (such as color histograms and cut/shot information) annotations. Additionally, since our annotation system is open for public, we must consider some reliability or correctness of annotation data. We also developed an automatic evaluation method of annotation reliability using the users' feedback. In the future, these fundamental technologies will contribute to the formation of new communities centered around video content.

  15. TAGmapper: a web-based tool for mapping SAGE tags.

    Bala, P; Georgantas, Robert W; Sudhir, D; Suresh, M; Shanker, K; Vrushabendra, B M; Civin, Curt I; Pandey, Akhilesh

    2005-12-30

    Serial Analysis of Gene Expression (SAGE) is an important means of obtaining quantitative information about expression of genes in different samples. Short SAGE tags are 10 nucleotides long and often contain enough information to uniquely identify the gene(s) corresponding to the tag. We have observed, however, that the currently available resources are not adequate for accurate mapping of all SAGE tags to genes. Here, we describe development of a web-based tool called TAGmapper (http://tagmapper.ibioinformatics.org), which provides a comprehensive and accurate mapping of SAGE tags to genes. We were able to map SAGE tags accurately in several instances where two other popular resources, SAGEmap (http://www.ncbi.nlm.nih.gov/projects/SAGE/) and SAGE Genie (http://cgap.nci.nih.gov/SAGE), provided incorrect or no assignment of tags to genes. Finally, we experimentally determined the expression of a subset of genes assigned by TAGmapper using DNA microarrays and/or quantitative PCR to confirm the reliability of the gene mappings. We anticipate that TAGmapper will be a useful tool in functional genomic approaches by providing accurate identification of genes in SAGE experiments.

Two formal evaluations were conducted in 2009 and 2010 using key informant interviews, usability interviews, focus groups, an online survey, and readability and suitability assessment tools. These methods provided users' perspectives on the overall design, content, and literacy demands of the website as well as valuable feedback on their interaction with the website. The authors subsequently redesigned Community Connect to Research, making significant improvements on the basis of what they learned from the evaluation. The second evaluation revealed that the redesign addressed many issues found in the first evaluation and identified additional areas of possible improvement. Overall, both evaluations suggested that participants believed that the website was useful and valuable, indicating that Community Connect to Research is a health information resource that provides patients and families with accessible, relevant, and high-quality information. Regular formal evaluation is an essential tool for effective ongoing enhancement of health information resources meant for the public.

    A great deal of ocean sensor observation data exists, for a wide range of marine disciplines, derived from in situ and remote observing platforms, in real-time, near-real-time and delayed mode. Ocean monitoring is routinely completed using sensors and instruments. Standardization is the key requirement for exchanging information about ocean sensors and sensor data and for comparing and combining information from different sensor networks. One or more sensors are often physically integrated into a single ocean `instrument' device, which often brings in many challenges related to diverse sensor data formats, parameters units, different spatiotemporal resolution, application domains, data quality and sensors protocols. To face these challenges requires the standardization efforts aiming at facilitating the so-called Sensor Web, which making it easy to provide public access to sensor data and metadata information. In this paper, a Marine Sensor Web, based on SOA and EDA and integrating the MBARI's PUCK protocol, IEEE 1451 and OGC SWE 2.0, is illustrated with a five-layer architecture. The Web Service layer and Event Process layer are illustrated in detail with an actual example. The demo study has demonstrated that a standard-based system can be built to access sensors and marine instruments distributed globally using common Web browsers for monitoring the environment and oceanic conditions besides marine sensor data on the Web, this framework of Marine Sensor Web can also play an important role in many other domains' information integration.

    Full Text Available The semantic web is the forthcoming technology in the world of search engine. It becomes mainly focused towards the search which is more meaningful rather than the syntactic search prevailing now. This proposed work concerns about the semantic search with respect to the educational domain. In this paper, we propose semantic web based efficient search using ontology and mathematical model that takes into account the misleading, unmatched kind of service information, lack of relevant domain knowledge and the wrong service queries. To solve these issues in this framework is designed to make three major contributions, which are ontology knowledge base, Natural Language Processing (NLP techniques and search model. Ontology knowledge base is to store domain specific service ontologies and service description entity (SDE metadata. The search model is to retrieve SDE metadata as efficient for Education lenders, which include mathematical model. The Natural language processing techniques for spell-check and synonym based search. The results are retrieved and stored in an ontology, which in terms prevents the data redundancy. The results are more accurate to search, sensitive to spell check and synonymous context. This paper reduces the user’s time and complexity in finding for the correct results of his/her search text and our model provides more accurate results. A series of experiments are conducted in order to respectively evaluate the mechanism and the employed mathematical model.

    2014-09-01

    Full Text Available The paper deals with design of a web-based system for Computer-Aided Manufacturing (CAM. Remote applications and databases located in the "private cloud" are proposed to be the basis of such system. The suggested approach contains: service - oriented architecture, using web applications and web services as modules, multi-agent technologies for implementation of information exchange functions between the components of the system and the usage of PDM - system for managing technology projects within the CAM. The proposed architecture involves CAM conversion into the corporate information system that will provide coordinated functioning of subsystems based on a common information space, as well as parallelize collective work on technology projects and be able to provide effective control of production planning. A system has been developed within this architecture which gives the possibility for a rather simple technological subsystems connect to the system and implementation of their interaction. The system makes it possible to produce CAM configuration for a particular company on the set of developed subsystems and databases specifying appropriate access rights for employees of the company. The proposed approach simplifies maintenance of software and information support for CAM subsystems due to their central location in the data center. The results can be used as a basis for CAM design and testing within the learning process for development and modernization of the system algorithms, and then can be tested in the extended enterprise.

    Traditionally, telemedicine systems have been designed to improve access to care by allowing physicians to consult a specialist about a case without sending the patient to another location, which may be difficult or time-consuming to reach. The cost of the equipment and network bandwidth needed for this consultation has restricted telemedicine use to contact between physicians instead of between patients and physicians. Recently, however, the wide availability of Internet connectivity and client and server software for e- mail, world wide web, and conferencing has made low-cost telemedicine applications feasible. In this work, we present a web-based system for asynchronous multimedia messaging between shoulder replacement surgery patients at home and their surgeons. A web browser plug-in was developed to simplify the process of capturing video and transferring it to a web site. The video capture plug-in can be used as a template to construct a plug-in that captures and transfers any type of data to a web server. For example, readings from home biosensor instruments (e.g., blood glucose meters and spirometers) that can be connected to a computing platform can be transferred to a home telemedicine web site. Both patients and doctors can access this web site to monitor progress longitudinally. The system has been tested with 3 subjects for the past 7 weeks, and we plan to continue testing in the foreseeable future.

    The present study aims to evaluate the quality of web-based information on gambling and to investigate potential content quality indicators. The following key words: gambling, pathological gambling, excessive gambling, gambling problem and gambling addiction were entered into two popular search engines: Google and Yahoo. Websites were assessed with a standardized proforma designed to rate sites on the basis of "accountability", "presentation", "interactivity", "readability" and "content quality". "Health on the Net" (HON) quality label, and DISCERN scale scores aiding people without content expertise to assess quality of written health publication were used to verify their efficiency as quality indicators. Of the 200 links identified, 75 websites were included. The results of the study indicate low scores on each of the measures. A composite global score appeared as a good content quality indicator. While gambling-related education websites for patients are common, their global quality is poor. There is a need for useful evidence-based information about gambling on the web. As the phenomenon has greatly increased, it could be relevant for Internet sites to improve their content by using global score as a quality indicator.

    Weng, Y. H.; Sun, F. S.

    2014-12-01

    A web-based field data management system has been designed and developed to allow field geologists to store, organize, manage, and share field data online. System requirements were analyzed and clearly defined first regarding what data are to be stored, who the potential users are, and what system functions are needed in order to deliver the right data in the right way to the right user. A 3-tiered architecture was adopted to create this secure, scalable system that consists of a web browser at the front end while a database at the back end and a functional logic server in the middle. Specifically, HTML, CSS, and JavaScript were used to implement the user interface in the front-end tier, the Apache web server runs PHP scripts, and MySQL to server is used for the back-end database. The system accepts various types of field information, including image, audio, video, numeric, and text. It allows users to select data and populate them on either Google Earth or Google Maps for the examination of the spatial relations. It also makes the sharing of field data easy by converting them into XML format that is both human-readable and machine-readable, and thus ready for reuse.

    2012-02-01

    Full Text Available Abstract Systematic reviews have become increasingly critical to informing healthcare policy; however, they remain a time-consuming and labor-intensive activity. The extraction of data from constituent studies comprises a significant portion of this effort, an activity which is often needlessly duplicated, such as when attempting to update a previously conducted review or in reviews of overlapping topics. In order to address these inefficiencies, and to improve the speed and quality of healthcare policy- and decision-making, we have initiated the development of the Systematic Review Data Repository, an open collaborative Web-based repository of systematic review data. As envisioned, this resource would serve as both a central archive and data extraction tool, shared among and freely accessible to organizations producing systematic reviews worldwide. A suite of easy-to-use software tools with a Web frontend would enable researchers to seamlessly search for and incorporate previously deposited data into their own reviews, as well as contribute their own. In developing this resource, we identified a number of technical and non-technical challenges, as well as devised a number of potential solutions, including proposals for systems and software tools to assure data quality, stratify and control user access effectively and flexibly accommodate all manner of study data, as well as means by which to govern and foster adoption of this new resource. Herein we provide an account of the rationale and development of the Systematic Review Data Repository thus far, as well as outline its future trajectory.

    The rate of performance improvements of the LHC at CERN has had a strong influence on the characteristics of the monitoring tools developed for the experiments. We present some of the latest additions to the suite of Web Based Monitoring services for the CMS experiment, and explore the aspects that address the roughly 20-fold increase in peak instantaneous luminosity over the course of 2011. One of these user-friendly tools allows collaborators to easily view, and make correlations among, accelerator configuration information such as bunch patterns, measured quantities such as intensities, vacuum pressures, and background conditions, as well as derived quantities such as luminosity and the number of simultaneous interactions per beam crossing. An additional tool summarizes the daily, weekly, and yearly luminosity and efficiency. Finally, we discuss a trigger cross section and rate fitting service that uses data from previous runs to validate current running conditions, as well as to serve as a predictive extrapolation tool for developing triggers for higher luminosity running.

    Full Text Available Web browsers are provided with complex information space where the volume of information available to them is huge. There comes the Recommender system which effectively recommends web pages that are related to the current webpage, to provide the user with further customized reading material. To enhance the performance of the recommender systems, we include an elegant proposed web based recommendation system; Truth Discovery based Content and Collaborative RECommender (TDCCREC which is capable of addressing scalability. Existing approaches such as Learning automata deals with usage and navigational patterns of users. On the other hand, Weighted Association Rule is applied for recommending web pages by assigning weights to each page in all the transactions. Both of them have their own disadvantages. The websites recommended by the search engines have no guarantee for information correctness and often delivers conflicting information. To solve them, content based filtering and collaborative filtering techniques are introduced for recommending web pages to the active user along with the trustworthiness of the website and confidence of facts which outperforms the existing methods. Our results show how the proposed recommender system performs better in predicting the next request of web users.

  8. Web Based Homework for CAPA in General Education Astronomy Courses

    Science.gov (United States)

    Robertson, T. H.

    2002-12-01

    Qualitative questions in astronomy have been developed to operate under the CAPA web-based homework system. Multiple versions of similar questions and software randomization are used to create different homework sets for each student. The questions are grouped by concept and subject to create more challenging activities from relatively simple questions. These questions have been used for three semesters in five sections of ASTRO 100 which enrolled a total of 500 students over the past two years. Student surveys consistently indicate that they like the system and believe that it helps them to learn. Cognitive measures in the form of exam and course grades do not demonstrate statistically significant improvement in sections which have used the new homework system. This is due in part to a conscious effort to create exam questions which focus on content understanding and not memorization and the persistent student habit of studying for exams by memorizing homework. Differences have been identified between female and male students in terms of completion rates and performance on homework, quiz and exam scores. This work was supported in part by funding from the George and Frances Ball Fund for Academic Excellence and the 21st Century Fund for Faculty Development.

    2015-08-01

    Practical training for the future use of the African VLBI Network (AVN) or any VLBI experiment starts by understanding the basic principles of radio observations and radio interferometry. The aim of this project is to build a basic interferometer that could be used remotely via a web interface from any country on the African continent. This should turn out as a much less expensive and much more efficient way to train AVN researchers from SKA partner countries to the principles of radio astronomy and to interferometric data analysis. The idea is based on the very successful EUHOU (European Hands-On Universe) already very successful in Europe. The former EUHOU manager, Dr Yannick Liebert, arrived for a 3 years postdoc with Prof Claude Carignan at the University of Cape Town to implement the same project on the African continent (AHI: African Hands-on Interferometry). Besides the use of AHI for the AVN researchers, this web-based system could be used be any undergraduate program on radio astronomical techniques across the African continent as the EUHOU is used all across Europe.

    2013-01-01

    We created a general framework for analysts to store and view data in a way that removes the boundaries created by operating systems, programming languages, and proximity. With the advent of HTML5 and CSS3 with JavaScript the distribution of information is limited to only those who lack a browser. We created a framework based on the methodology: one server, one web based application. Additional benefits are increased opportunities for collaboration. Today the idea of a group in a single room is antiquated. Groups will communicate and collaborate with others from other universities, organizations, as well as other continents across times zones. There are many varieties of data gathering and condition-monitoring software available as well as companies who specialize in customizing software to individual applications. One single group will depend on multiple languages, environments, and computers to oversee recording and collaborating with one another in a single lab. The heterogeneous nature of the system creates challenges for seamless exchange of data and ideas between members. To address these limitations we designed a framework to allow users seamless accessibility to their data. Our framework was deployed using the data feed on the NASA Ames' planetary rover testbed. Our paper demonstrates the process and implementation we followed on the rover.

    Full Text Available The application of web-based technologies in developing the knowledge network for planning and development is the topic of this paper. Despite the fact that the web phenomenon is relatively new in the profession and not yet entirely explored, there is evidence which suggests that e-services are amongst the most rapidly growing sectors in the profession today. Numerous e-technologies for planning purposes have already been developed, and often fully integrated into the planning practice. This paper explores the state of the art in the field, and discusses the way the e-based alternative could be utilized in everyday planning practice. At the outset, the existing know-how is presented, followed by the assessment of the tools against the principles of a good planning practice. The challenges to the alternative are highlighted in the last section, and debated vis-à-vis the observed benefits. Implications for concrete planning practice are at the heart of the overall discussion.

    2000-10-01

    With a wide range of student abilities in a class, it is difficult to effectively teach and stimulate all students. A series of web based tutorials was designed to help weaker students and stretch the stronger students. The tutorials consist of a series of HTML web pages with embedded Java applets. This combination is particularly powerful for providing interactive demonstrations because any textual content may be easily provided within the web page. The applet is able to be a compete working program that dynamically illustrates the concept, or provides a working environment for the student to experiment and work through their solution. The applet is dynamic, and responds to the student through both mouse clicks and keyboard entry. These allow the student to adjust parameters, make selections, and affect the way the program is run or information is displayed. Such interaction allows each applet to provide a mini demonstration or experiment to help the student understand a particular concept or technique. The approach taken is illustrated with a tutorial that dynamically shows the relationships between a truth table, Karnaugh amp, logic circuit and Boolean algebra representations of a logic function, and dramatically illustrates the effect of minimization on the resultant circuit. Use of the tutorial has resulted in significant benefits, particularly with weaker students.

    Full Text Available Web based interventions (WBIs have been developed for various health conditions. These include interventions for various psychoactive substance use disorders including tobacco and alcohol. Tobacco use has remained the single largest preventable cause of global mortality and morbidity for many years. It is responsible for around 6 million deaths annually world-wide. Ironically, most of the tobacco users reside in resource poor low and middle-income countries. The article reviews the existing literature on WBIs for management of tobacco use. The literature search was performed using MedLine, PubMed, PsycINFO, Embase and Cochrane Review for relevant English language articles published from 1998 up to 2013. There is limited support for effectiveness of WBIs for managing tobacco use among adolescents. Although most of the trials among adults found WBIs to be more effective at short term follow-up (a few days to weeks, the benefits failed to extend beyond 3 months in most of the studies. All but one interventions studied in a randomized controlled trial is for smoking forms.

    Full Text Available Introduction. Incidents of road rage are on a rise in India, but the literature is lacking in the aspect. There is an increasing realization of possibility of effective web based interventions to deliver public health related messages. Objective. The aim was to quantitatively evaluate risk factors among motor vehicle drivers using an internet based survey. Methods. Facebook users were evaluated using Life Orientation Test-Revised (LOT-R and Driving Anger Scale (DAS. Results. An adequate response rate of 65.9% and satisfactory reliability with sizable correlation were obtained for both scales. Age was found to be positively correlated to LOT-R scores (r=0.21; P=0.02 and negatively correlated to DAS scores (r=-0.19; P=0.03. Years of education were correlated to LOT-R scores (r=0.26; P=0.005 but not DAS scores (r=-0.14; P=0.11. LOT-R scores did not correlate to DAS scores. Conclusion. There is high prevalence of anger amongst drivers in India particularly among younger males. A short web survey formatted in easy to use question language can result in a feasible conduction of an online survey.

    2015-12-01

    Geocoding - the process of finding position based on descriptive data such as address or postal code - is considered as one of the most commonly used spatial analyses. Many online map providers such as Google Maps, Bing Maps and Yahoo Maps present geocoding as one of their basic capabilities. Despite the diversity of geocoding services, users usually face some limitations when they use available online geocoding services. In existing geocoding services, proximity and nearness concept is not modelled appropriately as well as these services search address only by address matching based on descriptive data. In addition there are also some limitations in display searching results. Resolving these limitations can enhance efficiency of the existing geocoding services. This paper proposes the idea of integrating fuzzy technique with geocoding process to resolve these limitations. In order to implement the proposed method, a web-based system is designed. In proposed method, nearness to places is defined by fuzzy membership functions and multiple fuzzy distance maps are created. Then these fuzzy distance maps are integrated using fuzzy overlay technique for obtain the results. Proposed methods provides different capabilities for users such as ability to search multi-part addresses, searching places based on their location, non-point representation of results as well as displaying search results based on their priority.

    2017-02-01

    Spatial data fusion plays an important role for spatial information retrieval from disconnected data sources and is thus a precondition for comprehensive and consistent decision making. In particular on the Web, it can help to combine spatial data from the variety of existing, but distributed sources, e.g. as provided by Spatial Data Infrastructure (SDI). However, standardized spatial data processing on the Web still lacks broad acceptance beyond the scientific domain. This article describes a formalization and service-based implementation of the spatial data fusion process. The formalization builds on a set theoretic description of the considered domain and derives a number of possible fusion objectives. Geoprocessing patterns are used to describe commonly used sub-routines of the fusion process and therefore support the workflow composition. The implementation is based on open standards and comprises a Web-client, several geoprocessing services and a fusion engine to support the Web-based compilation and execution of spatial data fusion workflows in an ad hoc manner.

  1. Opportunities for web-based indicators in environmental sciences.

    Full Text Available This paper proposes a set of web-based indicators for quantifying and ranking the relevance of terms related to key-issues in Ecology and Sustainability Science. Search engines that operate in different contexts (e.g. global, social, scientific are considered as web information carriers (WICs and are able to analyse; (i relevance on different levels: global web, individual/personal sphere, on-line news, and culture/science; (ii time trends of relevance; (iii relevance of keywords for environmental governance. For the purposes of this study, several indicators and specific indices (relational indices and dynamic indices were applied to a test-set of 24 keywords. Outputs consistently show that traditional study topics in environmental sciences such as water and air have remained the most quantitatively relevant keywords, while interest in systemic issues (i.e. ecosystem and landscape has grown over the last 20 years. Nowadays, the relevance of new concepts such as resilience and ecosystem services is increasing, but the actual ability of these concepts to influence environmental governance needs to be further studied and understood. The proposed approach, which is based on intuitive and easily replicable procedures, can support the decision-making processes related to environmental governance.

    Since the completion of the Saccharomyces cerevisiae genome sequencing project in 1996, the genomes of over 80 fungal species have been sequenced or are currently being sequenced. Resulting data provide opportunities for studying and comparing fungal biology and evolution at the genome level. To support such studies, the Comparative Fungal Genomics Platform (CFGP; http://cfgp.snu.ac.kr), a web-based multifunctional informatics workbench, was developed. The CFGP comprises three layers, including the basal layer, middleware and the user interface. The data warehouse in the basal layer contains standardized genome sequences of 65 fungal species. The middleware processes queries via six analysis tools, including BLAST, ClustalW, InterProScan, SignalP 3.0, PSORT II and a newly developed tool named BLASTMatrix. The BLASTMatrix permits the identification and visualization of genes homologous to a query across multiple species. The Data-driven User Interface (DUI) of the CFGP was built on a new concept of pre-collecting data and post-executing analysis instead of the 'fill-in-the-form-and-press-SUBMIT' user interfaces utilized by most bioinformatics sites. A tool termed Favorite, which supports the management of encapsulated sequence data and provides a personalized data repository to users, is another novel feature in the DUI.

  3. Web-Based Requesting and Scheduling Use of Facilities

    2010-01-01

    Automated User's Training Operations Facility Utilization Request (AutoFUR) is prototype software that administers a Web-based system for requesting and allocating facilities and equipment for astronaut-training classes in conjunction with scheduling the classes. AutoFUR also has potential for similar use in such applications as scheduling flight-simulation equipment and instructors in commercial airplane-pilot training, managing preventive- maintenance facilities, and scheduling operating rooms, doctors, nurses, and medical equipment for surgery. Whereas requesting and allocation of facilities was previously a manual process that entailed examination of documents (including paper drawings) from different sources, AutoFUR partly automates the process and makes all of the relevant information available via the requester s computer. By use of AutoFUR, an instructor can fill out a facility-utilization request (FUR) form on line, consult the applicable flight manifest(s) to determine what equipment is needed and where it should be placed in the training facility, reserve the corresponding hardware listed in a training-hardware inventory database, search for alternative hardware if necessary, submit the FUR for processing, and cause paper forms to be printed. Auto-FUR also maintains a searchable archive of prior FURs.

    Three web-based learning modules for introductory undergraduate astronomy courses are available at Indiana University Bloomington. The NovaSearch module allows students to view images of the core of the Andromeda Galaxy to discover novae and monitor their light curves. The Proper Pair module allows students to examine proper motion and parallax data from Hipparcos to determine if pairs of stars close together on the sky are true binary star systems. A third module, Astronomy in Color, allows students to produce color images using multi-wavelength data. The pedagogical goals of these curriculum materials are to teach that science is a process of discovery, not just a body of knowledge, to increase positive attitudes towards science by engaging students in discovery, and to motivate students towards pursuing STEM careers by giving students an opportunity to develop skills such as critical thinking, teamwork, and task focus that are important in any career path. The learning modules may be accessed at www.astro.indiana.edu/catyp/rbseu The development of these curriculum modules has been funded by the national Science Foundation through grant DUE-0618441.

  5. A web-based approach to data imputation

    KAUST Repository

    Li, Zhixu

    2013-10-24

    In this paper, we present WebPut, a prototype system that adopts a novel web-based approach to the data imputation problem. Towards this, Webput utilizes the available information in an incomplete database in conjunction with the data consistency principle. Moreover, WebPut extends effective Information Extraction (IE) methods for the purpose of formulating web search queries that are capable of effectively retrieving missing values with high accuracy. WebPut employs a confidence-based scheme that efficiently leverages our suite of data imputation queries to automatically select the most effective imputation query for each missing value. A greedy iterative algorithm is proposed to schedule the imputation order of the different missing values in a database, and in turn the issuing of their corresponding imputation queries, for improving the accuracy and efficiency of WebPut. Moreover, several optimization techniques are also proposed to reduce the cost of estimating the confidence of imputation queries at both the tuple-level and the database-level. Experiments based on several real-world data collections demonstrate not only the effectiveness of WebPut compared to existing approaches, but also the efficiency of our proposed algorithms and optimization techniques. © 2013 Springer Science+Business Media New York.

    Full Text Available When personal photo collections get large retrieval of specific photos or sets of photos becomes difficult mainly due to the fairly primitive means by which they are organised. Commercial photo handling systems help but often have only elementary searching features. In this paper, we describe an interactive web-based photo retrieval system that enables personal digital photo users to accomplish photo browsing by using multimodal interaction. This system not only enables users to use mouse click input modalities but also speech input modality to browse their personal digital photos in the World Wide Web (WWW environment. The prototype system and it architecture utilise web technology which was built using web programming scripting (JavaScript, XHTML, ASP, XML based mark-up language and image database in order to achieve its objective. All prototype programs and data files including the user’s photo repository, profiles, dialogues, grammars, prompt, and retrieval engine are stored and located in the web server. Our approach also consists of human-computer speech dialogue based on photo browsing of image content by four main categories (Who? What? When? and Where?. Our user study with 20 digital photo users showed that the participants reacted positively to their experience with the system interactions.

    This study examined the effects of a Web-based teaching method (versus a traditional lecture method) on undergraduate nursing students' learning of electrocardiography (ECG). The Web-based learning program was developed by the authors and implemented for 4 weeks. The study used a pretest-posttest experimental design. A total of 105 senior nursing students were recruited at a university in Korea. Fifty-four students were assigned to an experimental group in 2002, and 51 were assigned to a control group in 2003. Knowledge about ECG among students in the Web-based group was significantly lower than that of students in the control group (p ECG recordings was significantly higher among students in the Web-based group (p learning. The self-directed, Web-based ECG learning program appears to be effective in helping nursing students to interpret ECG recordings.

    United States students' science test scores are low, especially in problem solving, and traditional science instruction could be improved. Consequently, visual thinking, constructing science structures, and problem solving in a web-based environment may be valuable strategies for improving science learning. This ethnographic study examined the science learning of fifteen fourth grade students in an after school computer club involving diverse students at an inner city school. The investigation was done from the perspective of the students, and it described the processes of visual thinking, web page construction, and problem solving in a web-based environment. The study utilized informal group interviews, field notes, Visual Learning Logs, and student web pages, and incorporated a Standards-Based Rubric which evaluated students' performance on eight science and technology standards. The Visual Learning Logs were drawings done on the computer to represent science concepts related to the Food Chain. Students used the internet to search for information on a plant or animal of their choice. Next, students used this internet information, with the information from their Visual Learning Logs, to make web pages on their plant or animal. Later, students linked their web pages to form Science Structures. Finally, students linked their Science Structures with the structures of other students, and used these linked structures as models for solving problems. Further, during informal group interviews, students answered questions about visual thinking, problem solving, and science concepts. The results of this study showed clearly that (1) making visual representations helped students understand science knowledge, (2) making links between web pages helped students construct Science Knowledge Structures, and (3) students themselves said that visual thinking helped them learn science. In addition, this study found that when using Visual Learning Logs, the main overall ideas of the

    1999-12-01

    I have written an astronomical image processing and analysis program designed to run over the internet in a Java-compatible web browser. The program, Sky Image Processor (SIP), is accessible at the SIP webpage (http://www.phys.vt.edu/SIP). Since nothing is installed on the user's machine, there is no need to download upgrades; the latest version of the program is always instantly available. Furthermore, the Java programming language is designed to work on any computer platform (any machine and operating system). The program could be used with students in web-based instruction or in a computer laboratory setting; it may also be of use in some research or outreach applications. While SIP is similar to other image processing programs, it is unique in some important respects. For example, SIP can load images from the user's machine or from the Web. An instructor can put images on a web server for students to load and analyze on their own personal computer. Or, the instructor can inform the students of images to load from any other web server. Furthermore, since SIP was written with students in mind, the philosophy is to present the user with the most basic tools necessary to process and analyze astronomical images. Images can be combined (by addition, subtraction, multiplication, or division), multiplied by a constant, smoothed, cropped, flipped, rotated, and so on. Statistics can be gathered for pixels within a box drawn by the user. Basic tools are available for gathering data from an image which can be used for performing simple differential photometry, or astrometry. Therefore, students can learn how astronomical image processing works. Since SIP is not part of a commercial CCD camera package, the program is written to handle the most common denominator image file, the FITS format.

    Earth science educators need interactive tools to engage and enable students to better understand how Earth systems work over geologic time scales. The evolution of landforms is ripe for interactive, inquiry-based learning exercises because landforms exist all around us. The Web-based Interactive Landform Simulation Model - Grand Canyon (WILSIM-GC, http://serc.carleton.edu/landform/) is a continuation and upgrade of the simple cellular automata (CA) rule-based model (WILSIM-CA, http://www.niu.edu/landform/) that can be accessed from anywhere with an Internet connection. Major improvements in WILSIM-GC include adopting a physically based model and the latest Java technology. The physically based model is incorporated to illustrate the fluvial processes involved in land-sculpting pertaining to the development and evolution of one of the most famous landforms on Earth: the Grand Canyon. It is hoped that this focus on a famous and specific landscape will attract greater student interest and provide opportunities for students to learn not only how different processes interact to form the landform we observe today, but also how models and data are used together to enhance our understanding of the processes involved. The latest development in Java technology (such as Java OpenGL for access to ubiquitous fast graphics hardware, Trusted Applet for file input and output, and multithreaded ability to take advantage of modern multi-core CPUs) are incorporated into building WILSIM-GC and active, standards-aligned curricula materials guided by educational psychology theory on science learning will be developed to accompany the model. This project is funded NSF-TUES program.

    Electronic surveys are convenient, cost effective, and increasingly popular tools for collecting information. While the online platform allows researchers to recruit and enroll more participants, there is an increased risk of participant dropout in Web-based research. Often, these dropout trends are simply reported, adjusted for, or ignored altogether. To propose a conceptual framework that analyzes respondent attrition and demonstrates the utility of these methods with existing survey data. First, we suggest visualization of attrition trends using bar charts and survival curves. Next, we propose a generalized linear mixed model (GLMM) to detect or confirm significant attrition points. Finally, we suggest applications of existing statistical methods to investigate the effect of internal survey characteristics and patient characteristics on dropout. In order to apply this framework, we conducted a case study; a seventeen-item Informed Decision-Making (IDM) module addressing how and why patients make decisions about cancer screening. Using the framework, we were able to find significant attrition points at Questions 4, 6, 7, and 9, and were also able to identify participant responses and characteristics associated with dropout at these points and overall. When these methods were applied to survey data, significant attrition trends were revealed, both visually and empirically, that can inspire researchers to investigate the factors associated with survey dropout, address whether survey completion is associated with health outcomes, and compare attrition patterns between groups. The framework can be used to extract information beyond simple responses, can be useful during survey development, and can help determine the external validity of survey results.

    In the future, the training of competent dentists will need to take advantage of up-to-date digital technologies and learning practices. In order to accomplish this, the following goals should be considered: i) the design of 'customizable' web-based curriculum matrices that accommodate the training philosophies and resources of individual dental schools; ii) the development of digital instructional modules that can be incorporated or downloaded into specific parts of a curriculum; iii) the establishment of an e-consortium, which provides peer view and guidance in the design of teaching modules, and which is responsible for the storage, maintenance, and distribution of teaching modules within the consortium; iv) the development of central human and physical resources at each dental school to enable the seamless delivery of instructional modules in a variety of learning environments; and v) the assessment and provision of ICT training to students and faculty with respect to the use of computers and related digital technologies and educational software programmes. These goals should lead to the creation of a 'virtual dental school'. Within this project summative and formative evaluations should be performed during both the production and development of teaching material (e-learning material) and the learning process. During the learning process the following aspects should be measured and evaluated: i) students' behaviour; and ii) effectiveness, retention and the transfer of e-learned material into the clinical situation. To obtain evidence of the efficacy of e-learning material a certain amount of research has to be done in the near future. It is suggested that all parameters currently known have to be implemented during the development of a learning programme. Previous workers have evaluated the following elements with e-learning: i) planning, ii) programming and technical development, iii) learning behaviours, iv) learning outcomes of both the programme and the

The burden of obsessive compulsive disorder (OCD may lead persons with diagnosed or undiagnosed OCD, and their relatives, to search for good quality information on the Web. This study aimed to evaluate the quality of Web-based information on English-language sites dealing with OCD and to compare the quality of websites found through a general and a medically specialized search engine. Methods: Keywords related to OCD were entered into Google and OmniMedicalSearch. Websites were assessed on the basis of accountability, interactivity, readability, and content quality. The "Health on the Net" (HON quality label and the Brief DISCERN scale score were used as possible content quality indicators. Of the 235 links identified, 53 websites were analyzed. Results: The content quality of the OCD websites examined was relatively good. The use of a specialized search engine did not offer an advantage in finding websites with better content quality. A score ≥16 on the Brief DISCERN scale is associated with better content quality. Conclusion: This study shows the acceptability of the content quality of OCD websites. There is no advantage in searching for information with a specialized search engine rather than a general one. Practical implications: The Internet offers a number of high quality OCD websites. It remains critical, however, to have a provider–patient talk about the information found on the Web. Keywords: Internet, quality indicators, anxiety disorders, OCD, search engine

    2017-04-01

    The first version of web-based system for automatic aftershock hazard assessment is available at http://afcast.org/afcast. The system software downloads earthquake data every 2 hours from ANSS Comprehensive Earthquake Catalog (ComCat, http://earthquake.usgs.gov/data/comcat/) provided on-line by USGS. Currently the system is aimed to assess hazard of aftershocks of M5.5+ after earthquakes of M6.5+. The access to the system is unlimited to the registered users only. First, the system estimates in quasi real time mode an area where strong aftershocks are expected. This area is modeled by an ellipse and stadium (the locus of distances from a line segment not exceeding a given value), both centered and oriented according to the main shock rupture, estimated using epicenters of the first 12 hours aftershocks. The sizes of the areas are controlled by q part of earthquakes for 12 hours after the mainshock from the enclosed circle with radius of 0.03x10^M/2. The chosen q-values are based on retrospective (1980-2015) analysis of the error diagram and imply three forecasting strategies: "soft", "neutral" and "hard". The "soft" strategy minimizes false alarms at a reasonable rate of failures to predict. The "hard" strategy, in contrary, minimizes the rate of failures to predict at a reasonable area of alarms. The "neutral" strategy equalizes errors of two types. Three concentric ellipses or stadiums may serve as benchmarks for the choice corresponding to specific hazard reduction measures between the three strategies. Next, the system will estimate the period and magnitude of the strongest aftershock expected inside the alarm area. This research was carried out at the expense of the Russian Science Foundation (Project No. 16-17-00093).

    2009-12-01

    ANDRILL has embraced the web as a platform for facilitating collaboration and communicating science with educators, students and researchers alike. Two recent ANDRILL education and outreach projects, Project Circle 2008 and the Climate Change Student Summit, brought together classrooms from around the world to participate in cutting edge science. A large component of each project was the online collaboration achieved through project websites, blogs, and the GroupHub--a secure online environment where students could meet to send messages, exchange presentations and pictures, and even chat live. These technologies enabled students from different countries and time zones to connect and participate in a shared 'conversation' about climate change research. ANDRILL has also developed several interactive, web-based visualizations to make scientific drilling data more engaging and accessible to the science community and the public. Each visualization is designed around three core concepts that enable the Web 2.0 platform, namely, that they are: (1) customizable - a user can customize the visualization to display the exact data she is interested in; (2) linkable - each view in the visualization has a distinct URL that the user can share with her friends via sites like Facebook and Twitter; and (3) mashable - the user can take the visualization, mash it up with data from other sites or her own research, and embed it in her blog or website. The web offers an ideal environment for visualization and collaboration because it requires no special software and works across all computer platforms, which allows organizations and research projects to engage much larger audiences. In this presentation we will describe past challenges and successes, as well as future plans.

    Most centers utilize phone or written surveys to screen candidates who self-refer to be living kidney donors. To increase efficiency and reduce resource utilization, we developed a web-based application to screen kidney donor candidates. The aim of this study was to evaluate the use of this web-based application. Method and time of referral were tabulated and descriptive statistics summarized demographic characteristics. Time series analyses evaluated use over time. Between January 1, 2011 and March 31, 2012, 1200 candidates self-referred to be living kidney donors at our center. Eight hundred one candidates (67%) completed the web-based survey and 399 (33%) completed a phone survey. Thirty-nine percent of donors accessed the application on nights and weekends. Postimplementation of the web-based application, there was a statistically significant increase (p web-based application as opposed to telephone contact. Also, there was a significant increase (p = 0.025) in the total number of self-referrals post-implementation from 61 to 116 per month. An interactive web-based application is an effective strategy for the initial screening of donor candidates. The web-based application increased the ability to interface with donors, process them efficiently and ultimately increased donor self-referral at our center. © Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.

    A discussion of the application of metadata, paradata and embedded data in web-based survey research, using two completed Delphi surveys as examples. Metadata, paradata and embedded data use in web-based Delphi surveys has not been described in the literature. The rapid evolution and widespread use of online survey methods imply that paper-based Delphi methods will likely become obsolete. Commercially available web-based survey tools offer a convenient and affordable means of conducting Delphi research. Researchers and ethics committees may be unaware of the benefits and risks of using metadata in web-based surveys. Discussion paper. Two web-based, three-round Delphi surveys were conducted sequentially between August 2014 - January 2015 and April - May 2016. Their aims were to validate the Australian nurse practitioner metaspecialties and their respective clinical practice standards. Our discussion paper is supported by researcher experience and data obtained from conducting both web-based Delphi surveys. Researchers and ethics committees should consider the benefits and risks of metadata use in web-based survey methods. Web-based Delphi research using paradata and embedded data may introduce efficiencies that improve individual participant survey experiences and reduce attrition across iterations. Use of embedded data allows the efficient conduct of multiple simultaneous Delphi surveys across a shorter timeframe than traditional survey methods. The use of metadata, paradata and embedded data appears to improve response rates, identify bias and give possible explanation for apparent outlier responses, providing an efficient method of conducting web-based Delphi surveys. © 2017 John Wiley & Sons Ltd.

    A recombinant vector vaccine uses an attenuated virus, bacterium, or parasite as the carrier to express a heterologous antigen(s). Many recombinant vaccine vectors and related vaccines have been developed and extensively investigated. To compare and better understand recombinant vectors and vaccines, we have generated Vaxvec (http://www.violinet.org/vaxvec), the first web-based database that stores various recombinant vaccine vectors and those experimentally verified vaccines that use these vectors. Vaxvec has now included 59 vaccine vectors that have been used in 196 recombinant vector vaccines against 66 pathogens and cancers. These vectors are classified to 41 viral vectors, 15 bacterial vectors, 1 parasitic vector, and 1 fungal vector. The most commonly used viral vaccine vectors are double-stranded DNA viruses, including herpesviruses, adenoviruses, and poxviruses. For example, Vaxvec includes 63 poxvirus-based recombinant vaccines for over 20 pathogens and cancers. Vaxvec collects 30 recombinant vector influenza vaccines that use 17 recombinant vectors and were experimentally tested in 7 animal models. In addition, over 60 protective antigens used in recombinant vector vaccines are annotated and analyzed. User-friendly web-interfaces are available for querying various data in Vaxvec. To support data exchange, the information of vaccine vectors, vaccines, and related information is stored in the Vaccine Ontology (VO). Vaxvec is a timely and vital source of vaccine vector database and facilitates efficient vaccine vector research and development.

    Using educational technology does not necessarily make medical education more effective. There are many different kinds of technology available to the contemporary medical teacher and what constitutes effective use may depend on the technology, the learning situation and many other factors. Web-based multimedia instruction (WBMI) provides learners with self-directed independent learning opportunities based on didactic material enhanced with multimedia features such as video and animations. WBMI may be used to replace other didactic events (e.g. lectures) or it may be provided in addition to other learning opportunities. Clinical educators looking to use WBMI need to make sure that it will meet both their learners' needs and the program's needs, and it has to align to the contexts in which it is used. The following 12 tips have been developed to help guide faculty through some of the key features of the effective use of WBMI in clinical teaching programs. These tips are based on more than a decade developing, using and appraising WBMI in support of surgical clerkship education across the USA and beyond and they are intended both to inform individual uses of WBMI in clinical training and to guide the strategic use of WBMI in clinical clerkship curricula.

    OceanBrowser is a web-based visualization tool for gridded oceanographic data sets. Those data sets are typically four-dimensional (longitude, latitude, depth and time). OceanBrowser allows one to visualize horizontal sections at a given depth and time to examine the horizontal distribution of a given variable. It also offers the possibility to display the results on an arbitrary vertical section. To study the evolution of the variable in time, the horizontal and vertical sections can also be animated. Vertical section can be generated by using a fixed distance from coast or fixed ocean depth. The user can customize the plot by changing the color-map, the range of the color-bar, the type of the plot (linearly interpolated color, simple contours, filled contours) and download the current view as a simple image or as Keyhole Markup Language (KML) file for visualization in applications such as Google Earth. The data products can also be accessed as NetCDF files and through OPeNDAP. Third-party layers from a web map service can also be integrated. OceanBrowser is used in the frame of the SeaDataNet project (http://gher-diva.phys.ulg.ac.be/web-vis/) and EMODNET Chemistry (http://oceanbrowser.net/emodnet/) to distribute gridded data sets interpolated from in situ observation using DIVA (Data-Interpolating Variational Analysis).

  7. A web-based system for the integrated water management

    2003-04-01

    The success of complexity theory has posed new challenges also in the environmental resources management. From the complexity point of view, in fact, the environment has to be considered as a system with numerous parts interrelated each other by strongly and no-linear feedback relationships. In this perspective, when an action is performed its results become difficult to control. Therefore, to construct and to select the most suitable alternatives for environmental resources management, an holistic approach has to be adopted. In water resources management domain, increasing interest is posed to the integrated management, in which the total system of biotic and a-biotic elements of certain water environment is taken into account. Our contribution moves from the idea that the term integrated has to be referred also to human agents which take decisions influencing the water environment. In other words, Integrated Water Management (IWM) considers how different action affect, and can reinforce, each other and it promotes the coordinated development and management of water, land and related resources. The IWM stresses the interrelationships among the actions at different types, working at different levels of influence, coordinating stakeholders' actions. The coordination requires an appropriate information level about the strategies used by each stakeholder. To improve the information flow inside a watershed and therefore the coordination among agents, a web-based system is proposed. It could be defined as an electronic agora where a set of stakeholders can be involved both in information exchange and in conflicts resolution. More in detail, to improve the coordination process, the proposed system allows the stakeholders to find someone with similar or conflicting interests to collaborate with; to make contact with selected people; to build a common understanding (that is the identification of a common goal, the negotiation about the way this goal should be reached); to

    It is well recognized that the need of sharing ocean data among non-specialized users is constantly increasing. Initiatives that are built upon international standards will contribute to simplify data processing and dissemination, improve user-accessibility also through web browsers, facilitate the sharing of information across the integrated network of ocean observing systems; and ultimately provide a better understanding of the ocean functioning. The SCHeMA (Integrated in Situ Chemical MApping probe) Project is developing an open and modular sensing solution for autonomous in situ high resolution mapping of a wide range of anthropogenic and natural chemical compounds coupled to master bio-physicochemical parameters (www.schema-ocean.eu). The SCHeMA web system is designed to ensure user-friendly data discovery, access and download as well as interoperability with other projects through a dedicated interface that implements the Global Earth Observation System of Systems - Common Infrastructure (GCI) recommendations and the international Open Geospatial Consortium - Sensor Web Enablement (OGC-SWE) standards. This approach will insure data accessibility in compliance with major European Directives and recommendations. Being modular, the system allows the plug-and-play of commercially available probes as well as new sensor probess under development within the project. The access to the network of monitoring probes is provided via a web-based system interface that, being implemented as a SOS (Sensor Observation Service), is providing standard interoperability and access tosensor observations systems through O&M standard - as well as sensor descriptions - encoded in Sensor Model Language (SensorML). The use of common vocabularies in all metadatabases and data formats, to describe data in an already harmonized and common standard is a prerequisite towards consistency and interoperability. Therefore, the SCHeMA SOS has adopted the SeaVox common vocabularies populated by

  9. Web-based Academic Roadmaps for Careers in the Geosciences

    Science.gov (United States)

    To a greater extent than most science programs, geology is underrepresented in K-12 curricula and the media. Thus potential majors have scant knowledge of academic requirements and career trajectories, and their idea of what geologists do--if they have one at all--is outdated. We have addressed these concerns by developing a dynamic, web-based academic roadmap for current and prospective students, their families, and others who are contemplating careers in the geosciences. The goals of this visually attractive "educational pathway" are to not only improve student recruitment and retention, but to empower student learning by creating better communication and advising tools that can render our undergraduate program transparent for learners and their families. Although we have developed academic roadmaps for four environmental and life science programs at the University of Rhode Island, we focus here on the roadmap for the geosciences, which illustrates educational pathways along the academic and early-career continuum for current and potential (i.e., high school) students who are considering the earth sciences. In essence, the Geosciences Academic Roadmap is a "one-stop'" portal to the discipline. It includes user- friendly information about our curriculum, outcomes (which at URI are tightly linked to performance in courses and the major), extracurricular activities (e.g., field camp, internships), careers, graduate programs, and training. In the presentation of this material extensive use is made of streaming video, interviews with students and earth scientists, and links to other relevant sites. Moreover, through the use of "Hot Topics", particular attention is made to insure that examples of geoscience activities are not only of relevance to today's students, but show geologists using the modern methods of the discipline in exciting ways. Although this is a "work-in-progress", evaluation of the sites, by high school through graduate students, has been strongly

  10. Phased development of a web-based PACS viewer

    The Web browser is an excellent environment for the rapid development of an effective and inexpensive PACS viewer. In this paper we will share our experience in developing a browser-based viewer, from the inception and prototype stages to its current state of maturity. There are many operational advantages to a browser-based viewer, even when native viewers already exist in the system (with multiple and/or high resolution screens): (1) It can be used on existing personal workstations throughout the hospital. (2) It is easy to make the service available from physician's homes. (3) The viewer is extremely portable and platform independent. There is a wide variety of means available for implementing the browser- based viewer. Each file sent to the client by the server can perform some end-user or client/server interaction. These means range from HTML (for HyperText Markup Language) files, through Java Script, to Java applets. Some data types may also invoke plug-in code in the client, although this would reduce the portability of the viewer, it would provide the needed efficiency in critical places. On the server side the range of means is also very rich: (1) A set of files: html, Java Script, Java applets, etc. (2) Extensions of the server via cgi-bin programs, (3) Extensions of the server via servlets, (4) Any other helper application residing and working with the server to access the DICOM archive. The viewer architecture consists of two basic parts: The first part performs query and navigation through the DICOM archive image folders. The second part does the image access and display. While the first part deals with low data traffic, it involves many database transactions. The second part is simple as far as access transactions are concerned, but requires much more data traffic and display functions. Our web-based viewer has gone through three development stages characterized by the complexity of the means and tools employed on both client and server sides.

    Full Text Available The shift of information form that is more technological oriented has encouraged EFL teachers to develop their students’ literacy skill. This study used web based resources in order to motivate EFL learning and develop students’ digital literacy. In conducting this study, twenty students were involved. The data were collected by means of questionnaires consisting of five aspects; students’ self-efficacy, learning challenge, learning curiosity, learning involvement and recognition for digital learning. The results of the study show that students are motivated by the use of web-based resources in EFL learning with more appropriate and authentic materials. However, some considerations are needed to be taken into account in selecting the suitable web-based resources. Using web based resources can be an alternative to help the students be motivated in developing their digital literacy learning.

    2009-08-01

    Continuing professional education is essential for nurses to update their clinical skills and knowledge to meet the complex demands of current patient care. Compared to traditional in-class continuing education, a web-based learning system is efficient for nurses with a three shift-working schedule and is timely to deliver knowledge about newly emerging epidemics such as Severe Acute Respiratory Syndrome. Many studies reveal the advantages of various web-based learning systems but seldom evaluate them from the perspective of quality. This study develops an instrument to assess the quality of a web-based learning system for nurses' continuing education based on the quality dimensions of a mature information systems success model. The research results show that all indicators of the instrument provide a fit to the quality measurement of a web-based learning system and have high reliability and validity. Based on the research findings, implications and limitations are discussed.

    Web-based synoptic reporting has been successfully integrated into diverse fields of pathology, improving efficiency and reducing typographic errors. Coagulation is a challenging field for practicing pathologists and pathologists-in-training alike. To develop a Web-based program that can expedite the generation of a individualized interpretive report for a variety of coagulation tests. We developed a Web-based synoptic reporting system composed of 119 coagulation report templates and 38 thromboelastography (TEG) report templates covering a wide range of findings. Our institution implemented this reporting system in July 2011; it is currently used by pathology residents and attending pathologists. Feedback from the users of these reports have been overwhelmingly positive. Surveys note the time saved and reduced errors. Our easily accessible, user-friendly, Web-based synoptic reporting system for coagulation is a valuable asset to our laboratory services.

    Although web-based interventions for promoting health and health-related behavior can be effective, poor adherence is a common issue that needs to be addressed. Technology as a means to communicate the content in web-based interventions has been neglected in research. Indeed, technology is often seen as a black-box, a mere tool that has no effect or value and serves only as a vehicle to deliver intervention content. In this paper we examine technology from a holistic perspective. We see it as a vital and inseparable aspect of web-based interventions to help explain and understand adherence. This study aims to review the literature on web-based health interventions to investigate whether intervention characteristics and persuasive design affect adherence to a web-based intervention. We conducted a systematic review of studies into web-based health interventions. Per intervention, intervention characteristics, persuasive technology elements and adherence were coded. We performed a multiple regression analysis to investigate whether these variables could predict adherence. We included 101 articles on 83 interventions. The typical web-based intervention is meant to be used once a week, is modular in set-up, is updated once a week, lasts for 10 weeks, includes interaction with the system and a counselor and peers on the web, includes some persuasive technology elements, and about 50% of the participants adhere to the intervention. Regarding persuasive technology, we see that primary task support elements are most commonly employed (mean 2.9 out of a possible 7.0). Dialogue support and social support are less commonly employed (mean 1.5 and 1.2 out of a possible 7.0, respectively). When comparing the interventions of the different health care areas, we find significant differences in intended usage (p=.004), setup (pdesign a web-based intervention to which patients are more likely to adhere.

    The Internet is becoming the preferred place to find information. Millions of people go online in search of health and medical information. Likewise, the demand for Web-based courses is growing. This paper presents the development, utilization, and evaluation of a Web-based e-learning course for nursing students, entitled Integration of Pathophysiology into Pharmacology. The pathophysiology component included cardiovascular, respiratory, central nervous and immune system diseases, while the pharmacology component was developed based on 150 commonly used drugs. One hundred and nineteen Year 1 nursing students took part in the course. The Web-based e-learning course materials were uploaded to a WebCT for students' self-directed learning and attempts to pass two scheduled online quizzes. At the end of the semester, students were given a questionnaire to measure the e-learning experience. Their experience in the e-learning course was a positive one. Students stated that they were able to understand rather than memorize the subject content, and develop their problem solving and critical thinking abilities. Online quizzes yielded satisfactory results. In the focus group interview, students indicated that they appreciated the time flexibility and convenience associated with Web-based learning, and also made good suggestions for enhancing Web-based learning. The Web-based approach is promising for teaching and learning pathophysiology and pharmacology for nurses and other healthcare professionals.

    There is a great concern on how to build up an interoperable health information system of public health and health information technology within the development of public information and health surveillance programme. Technically, some major issues remain regarding to health data visualization, spatial processing of health data, health information dissemination, data sharing and the access of local communities to health information. In combination with GIS, we propose a technical framework for web-based health data visualization and spatial analysis. Data was collected from open map-servers and geocoded by open data kit package and data geocoding tools. The Web-based system is designed based on Open-source frameworks and libraries. The system provides Web-based analyst tool for pattern detection through three spatial tests: Nearest neighbour, K function, and Spatial Autocorrelation. The result is a web-based GIS, through which end users can detect disease patterns via selecting area, spatial test parameters and contribute to managers and decision makers. The end users can be health practitioners, educators, local communities, health sector authorities and decision makers. This web-based system allows for the improvement of health related services to public sector users as well as citizens in a secure manner. The combination of spatial statistics and web-based GIS can be a solution that helps empower health practitioners in direct and specific intersectional actions, thus provide for better analysis, control and decision-making.

  11. Evolution of Web-Based Applications Using Domain-Specific Markup Languages

    2000-11-01

    Full Text Available The lifecycle of Web-based applications is characterized by frequent changes to content, user interface, and functionality. Updating content, improving the services provided to users, drives further development of a Web-based application. The major goal for the success of a Web-based application becomes therefore its evolution. Though, development and maintenance of Web-based applications suffers from the underlying document-based implementation model. A disciplined evolution of Web based applications requires the application of software engineering practice for systematic further development and reuse of software artifacts. In this contribution we suggest to adopt the component paradigm to development and evolution of Web-based applications. The approach is based on a dedicated component technology and component-software architecture. It allows abstracting from many technical aspects related to the Web as an application platform by introducing domain specific markup languages. These languages allow the description of services, which represent domain components in our Web-component-software approach. Domain experts with limited knowledge of technical details can therefore describe application functionality and the evolution of orthogonal aspects of the application can be de-coupled. The whole approach is based on XML to achieve the necessary standardization and economic efficiency for the use in real world projects.

  12. A changing landscape: web-based methods for dietary assessment in adolescents.

    Storey, Kate E

    2015-09-01

    Adolescents' dietary intake is an important determinant of health and well-being and is influenced by a complex interaction of environmental, social, psychological, and physiological factors. The complexity of the adolescent diet makes its assessment prone to error, which has prompted researchers and clinicians to turn to technology to reduce this error. Previous reviews have been conducted regarding the use of technology in dietary assessment for adults; however, there are no known reviews for adolescents. Therefore, the purpose of this review is to describe the practical considerations for web-based dietary assessment methods and to evaluate recent evidence on their validity and implications. There are numerous web-based dietary assessment methods that are available, valid, and reliable for use in the adolescent population. Web-based methods include both native and web-based applications (or 'apps'), and have been developed for use as food records, 24-h dietary recalls, and food frequency questionnaires. Web-based methods provide an efficient, cost-effective and practical solution to assess dietary intake; they are less burdensome to respondents and reduce errors and bias. Furthermore, adolescents are technologically savvy and often prefer the use of technology. Web-based methods should be considered when assessing adolescents' dietary intake.

    Within academic settings, students experience varied emotions and interest towards learning. Although both emotions and interest can increase students' likelihood to engage in traditional learning, little is known about the influence of emotions and interest in learning activities in a web-based learning environment (WBLE). This study examined how emotions experienced while using a WBLE, students' interest towards the course topic and interest towards web-based learning are associated with collaborative visible and non-collaborative invisible activities and 'lurking' in the WBLE. Participants were 99 Finnish university students from five web-based courses. All the students enrolled in the courses filled out pre- and post-test questionnaires of interest, and repeatedly completed an on-line questionnaire on emotions experienced while using the WBLE during the courses. The fluctuation of emotional reactions was positively associated with both visible collaborative and invisible non-collaborative activities in the WBLE. Further, interest towards the web-based learning was positively associated with invisible activity. The results also demonstrated that students not actively participating in the collaborative activities (i.e. lurkers) had more negative emotional experiences during the courses than other students. The results highlight the distinct impacts that emotions and interest have on different web-based learning activities and that they should be considered when designing web-based courses.

    Web-based distance learning is considered a promising approach to replace or supplement conventional nursing instruction. However, no systematic review has been seen to explore the effect of web-based distance education in nursing. To examine the efficacy of the web-based distance education for nursing students and employed nurses. A systematic review of randomized controlled studies was undertaken. Multiple search strategies were performed in PubMed and Embase until July 2012. Two reviewers independently selected trials, conducted quality critical appraisal, and extracted the data from the included studies. Nine randomized controlled trials met inclusion criteria, among which five studies were rated as A quality level, and the other four studies as B quality level. The results showed that web-based distance learning has produced equivalent or better effects in knowledge acquisition. For nursing skill performance, four studies revealed a positive role for the new teaching mode, and one study showed a negative viewpoint. This review also demonstrated that participants generally accepted web-based education with high satisfaction rates. Two studies reported a more positive trend for self-efficacy in performing nursing skills in the experiment group compared with control group. Some negative feedbacks were also expressed. Web-based education has encouraging effects in improving both participants' knowledge and skills performance, and in enhancing self-efficacy in performing nursing skills, with a high satisfaction rate expressed by participants. More rigorous experimental studies are advocated. © 2013 The Authors. International Nursing Review © 2013 International Council of Nurses.

    Screening toddlers for autism spectrum disorder (ASD) with the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) has been shown to lower age of diagnosis by 2 years. In order to streamline ASD screening, research is exploring the use of web-based screening during well-child checkups. The current study examined implementation of the web-based M-CHAT-R in an urban pediatric clinic in Atlanta, Georgia. Toddlers (N = 2557; 87% African American) were screened during well-child visits (Mage = 22.43 months, SD = 3.65). Using the web-based version resulted in a 58.5% increase in the number of cases screened per month. A similar proportion of toddlers in each modality screened positive (P = .43), but significantly fewer children were missing "Follow-up" in the web-based administration (P web-based screening in underserved populations. Future research is necessary to understand factors that facilitate successful implementation of web-based ASD screening.

    We determined the Web-based configurations that are applied to teach medical and veterinary communication skills, evaluated their effectiveness, and suggested future educational directions for Web-based communication teaching in veterinary education. We performed a systematic search of CAB Abstracts, MEDLINE, Scopus, and ERIC limited to articles published in English between 2000 and 2012. The review focused on medical or veterinary undergraduate to clinical- or residency-level students. We selected studies for which the study population was randomized to the Web-based learning (WBL) intervention with a post-test comparison with another WBL or non-WBL method and that reported at least one empirical outcome. Two independent reviewers completed relevancy screening, data extraction, and synthesis of results using Kirkpatrick and Kirkpatrick's framework. The search retrieved 1,583 articles, and 10 met the final inclusion criteria. We identified no published articles on Web based communication platforms in veterinary medicine; however, publications summarized from human medicine demonstrated that WBL provides a potentially reliable and valid approach for teaching and assessing communication skills. Student feedback on the use of virtual patients for teaching clinical communication skills has been positive,though evidence has suggested that practice with virtual patients prompted lower relation-building responses.Empirical outcomes indicate that WBL is a viable method for expanding the approach to teaching history taking and possibly to additional tasks of the veterinary medical interview.

    Cities are like living entities, needing a continuous throughput of resources and energy for survival and growth, creating waste in the process. This paper documents the Bangalore Urban Mapping Project: an initiative that uses this metabolic concept [1],[2]. to inform comprehensive planning in the rapidly growing software capital of Bangalore city in India. Focusing on demographic growth, and water supply and consumption in its first phase, a web-based geo-portal has been developed for two purposes - interactive information communication and delivery, and online planning in the water supply sector. The application, titled Bangalore Urban Mapping Project (BUMP) is built on a free and open source web GIS stack consisting of a Postgis database, PHP, OpenLayers, and Apache Web Server deployed on a 64-bit Ubuntu Linux server platform. The interactive planning portion of the application allows BUMP users to build, run and visualize demographic growth, water supply, and growth scenarios on the browser. Application logic is written in PHP to connect the many components of the interactive application, which is available on the BUMP website (http://www.seimapping.org/bump/index.php). It relies on AJAX to fetch layer data from the server and render the layer using OpenLayers on the fly. This allows users to view multiple layers at the same time without refreshing the page. Data is packed in GeoJSON format and is compressed to reduce traffic. The information communication portion of the application provides thematic representation of each of twenty different map layers, graphical and tabular summaries of demographic and water data that are presented dynamically using Javascript libraries including the Google Chart API. The application also uses other common Javascript libraries/plug-ins, like jQuery, jQuery UI, qTip, to ease the development and to ensure cross-browser compatibility. The planning portion of the platform allows the user to interact with a scenario explorer

    , who can use it to prepare their lessons, retrieve information and organize the didactic material in order to support their lessons. We think it important to use a user centered "psychology" based on UM: we have to know the needs and expectations of the students. Our intent is to use usability tests not just to prove the site effectiveness and clearness, but also to investigate aesthetical preferences of children and young people. Physics, mathematics, chemistry are just some of the difficult learning fields connected with space technologies. Space culture is a potentially never-ending field, and our scope will be to lead students by hand in this universe of knowledge. This paper will present MARS activities in the framework of the above methodologies aimed at implementing a web based approach to integrate space culture and education. The activities are already in progress and some results will be presented in the final paper.

    2002-09-01

    Medical students are presented with unique challenges when they care for patients with limited English proficiency. Students must learn a complex set of skills needed to care for patients across cultural and language barriers and to understand the impact of their own attitudes and beliefs about caring for these patients. We developed and piloted a multimedia interactive Web-based module aimed at teaching students effective strategies for working with interpreters and diverse patient populations, and at raising their awareness of important legal, ethical, and cultural issues. First the learner completes a 37-multiple-choice-question (MCQ) pre-test that assesses attitudes, factual knowledge, and ability to analyze written clinical scenarios relevant to the module's content. Learners are then shown a series of professionally produced video vignettes, which reflect diverse patient populations, interpreters, and effectiveness of interpretation strategies (e.g., a Russian-speaking woman with chest pain whose daughter interprets, a medical student interpreting for a Chinese-speaking man using herbal medication, a Haitian woman told of an abnormal mammogram through a trained simultaneous interpreter). In each case, learners submit short answers to on-screen questions analyzing the effectiveness of the interpretation strategies demonstrated. Immediate feedback is given comparing student responses with those of experts. At any time during the module, the learners may view video commentary by legal, ethics, and cultural experts, or access a glossary and Web site links. Students conclude the module by again taking the MCQ test. A final screen compares their pre- and post-MCQ test responses and shows best answers, allowing them to assess their learning. The learners also complete a survey, providing personal cultural information and feedback on the module. All 160 first-year medical students completed the module and evaluated its effectiveness this year. On average, students

    2012-12-01

    Digital, field and virtual Semantic Web-based education (SWBE) of geological mapping requires the construction of a set of searchable, reusable, and interoperable digital learning objects (LO) for learners, teachers, and authors. These self-contained units of learning may be text, image, or audio, describing, for example, how to calculate the true dip of a layer from two structural contours or find the apparent dip along a line of section. A collection of multi-media LOs can be integrated, through domain and task ontologies, with mapping-related learning activities and Web services, for example, to search for the description of lithostratigraphic units in an area, or plotting orientation data on stereonet. Domain ontologies (e.g., GeologicStructure, Lithostratigraphy, Rock) represent knowledge in formal languages (RDF, OWL) by explicitly specifying concepts, relations, and theories involved in geological mapping. These ontologies are used by task ontologies that formalize the semantics of computational tasks (e.g., measuring the true thickness of a formation) and activities (e.g., construction of cross section) for all actors to solve specific problems (making map, instruction, learning support, authoring). A SWBE system for geological mapping should also involve ontologies to formalize teaching strategy (pedagogical styles), learner model (e.g., for student performance, personalization of learning), interface (entry points for activities of all actors), communication (exchange of messages among different components and actors), and educational Web services (for interoperability). In this ontology-based environment, actors interact with the LOs through educational servers, that manage (reuse, edit, delete, store) ontologies, and through tools which communicate with Web services to collect resources and links to other tools. Digital geological mapping involves a location-based, spatial organization of geological elements in a set of GIS thematic layers. Each layer

    Mazzarella, J. M.; NED Team

    The NASA/IPAC Extragalactic Database (NED) is a thematic, web-based research facility in widespread use by scientists, educators, space missions, and observatory operations for observation planning, data analysis, discovery, and publication of research about objects beyond our Milky Way galaxy. NED is a portal into a systematic fusion of data from hundreds of sky surveys and tens of thousands of research publications. The contents and services span the entire electromagnetic spectrum from gamma rays through radio frequencies, and are continuously updated to reflect the current literature and releases of large-scale sky survey catalogs. NED has been on the Internet since 1990, growing in content, automation and services with the evolution of information technology. NED is the world's largest database of crossidentified extragalactic objects. As of December 2006, the system contains approximately 10 million objects and 15 million multi-wavelength cross-IDs. Over 4 thousand catalogs and published lists covering the entire electromagnetic spectrum have had their objects cross-identified or associated, with fundamental data parameters federated for convenient queries and retrieval. This chapter describes the interoperability of NED services with other components of the Virtual Observatory (VO). Section 1 is a brief overview of the primary NED web services. Section 2 provides a tutorial for using NED services currently available through the NVO Registry. The "name resolver" provides VO portals and related internet services with celestial coordinates for objects specified by catalog identifier (name); any alias can be queried because this service is based on the source cross-IDs established by NED. All major services have been updated to provide output in VOTable (XML) format that can be accessed directly from the NED web interface or using the NVO registry. These include access to images via SIAP, Cone- Search queries, and services providing fundamental, multi

    2016-01-01

    Background The adolescent and early adult years are periods of peak prevalence and incidence for most mental disorders. Despite the rapid expansion of Web-based mental health care, and increasing evidence of its effectiveness, there is little research investigating the characteristics of young people who access Web-based mental health care. headspace, Australia’s national youth mental health foundation, is ideally placed to explore differences between young people who seek Web-based mental health care and in-person mental health care as it offers both service modes for young people, and collects corresponding data from each service type. Objective The objective of this study was to provide a comprehensive profile of young people seeking Web-based mental health care through eheadspace (the headspace Web-based counseling platform), and to compare this with the profile of those accessing help in-person through a headspace center. Methods Demographic and clinical presentation data were collected from all eheadspace clients aged 12 to 25 years (the headspace target age range) who received their first counseling session between November 1, 2014 and April 30, 2015 via online chat or email (n=3414). These Web-based clients were compared with all headspace clients aged 12 to 25 who received their first center-based counseling service between October 1, 2014 and March 31, 2015 (n=20,015). Results More eheadspace than headspace center clients were female (78.1% compared with 59.1%), and they tended to be older. A higher percentage of eheadspace clients presented with high or very high levels of psychological distress (86.6% compared with 73.2%), but they were at an earlier stage of illness on other indicators of clinical presentation compared with center clients. Conclusions The findings of this study suggest that eheadspace is reaching a unique client group who may not otherwise seek help or who might wait longer before seeking help if in-person mental health support was

    Mindfulness-based interventions (MBIs) are becoming increasingly popular for helping people with physical health conditions. Expanding from traditional face-to-face program delivery, there is growing interest in Web-based application of MBIs, though Web-based MBIs for people with physical health conditions specifically have not been thoroughly reviewed to date. The objective of this paper was to review Web-based MBIs for people with physical health conditions and to examine all outcomes reported (eg, efficacy or effectiveness for physical changes or psychological changes; feasibility). Databases PubMed, PsycINFO, Science Direct, CINAHL Plus, and Web of Science were searched. Full-text English papers that described any Web-based MBI, examining any outcome, for people with chronic physical health conditions were included. Randomized, nonrandomized, controlled, and uncontrolled trials were all included. Extracted data included intervention characteristics, population characteristics, outcomes, and quality indicators. Intervention characteristics (eg, synchronicity and guidance) were examined as potential factors related to study outcomes. Of 435 publications screened, 19 published papers describing 16 studies were included. They examined Web-based MBIs for people with cancer, chronic pain or fibromyalgia, irritable bowel syndrome (IBS), epilepsy, heart disease, tinnitus, and acquired brain injury. Overall, most studies reported positive effects of Web-based MBIs compared with usual care on a variety of outcomes including pain acceptance, coping measures, and depressive symptoms. There were mixed results regarding the effectiveness of Web-based MBIs compared with active control treatment conditions such as cognitive behavioral therapy. Condition-specific symptoms (eg, cancer-related fatigue and IBS symptoms) targeted by treatment had the largest effect size improvements following MBIs. Results are inconclusive regarding physical variables. Preliminary evidence suggests

    Uniformity testing is performed daily to ensure adequate camera performance before clinical use. The aim of this study is to assess the reliability of Beth Israel Deaconess Medical Center's locally built, centralized, Web-based uniformity analysis system by examining the differences between manufacturer and Web-based National Electrical Manufacturers Association integral uniformity calculations measured in the useful field of view (FOV) and the central FOV. Manufacturer and Web-based integral uniformity calculations measured in the useful FOV and the central FOV were recorded over a 30-d period for 4 cameras from 3 different manufacturers. These data were then statistically analyzed. The differences between the uniformity calculations were computed, in addition to the means and the SDs of these differences for each head of each camera. There was a correlation between the manufacturer and Web-based integral uniformity calculations in the useful FOV and the central FOV over the 30-d period. The average differences between the manufacturer and Web-based useful FOV calculations ranged from -0.30 to 0.099, with SD ranging from 0.092 to 0.32. For the central FOV calculations, the average differences ranged from -0.163 to 0.055, with SD ranging from 0.074 to 0.24. Most of the uniformity calculations computed by this centralized Web-based uniformity analysis system are comparable to the manufacturers' calculations, suggesting that this system is reasonably reliable and effective. This finding is important because centralized Web-based uniformity analysis systems are advantageous in that they test camera performance in the same manner regardless of the manufacturer.

    The purpose of this study was to explore the relationships between job characteristics (job demands, job control and social support) and nurses' attitudes toward web-based continuing learning. A total of 221 in-service nurses from hospitals in Taiwan were surveyed. The Attitudes toward Web-based Continuing Learning Survey (AWCL) was employed as the outcome variables, and the Chinese version Job Characteristic Questionnaire (C-JCQ) was administered to assess the predictors for explaining the nurses' attitudes toward web-based continuing learning. To examine the relationships among these variables, hierarchical regression was conducted. The results of the regression analysis revealed that job control and social support positively associated with nurses' attitudes toward web-based continuing learning. However, the relationship of job demands to such learning was not significant. Moreover, a significant demands×job control interaction was found, but the job demands×social support interaction had no significant relationships with attitudes toward web-based continuing learning.

    This study explored gender differences on university students' attitudes toward Web-based learning in Taiwan. A Web-based Learning Attitude Survey (WLAS) was developed. The WLAS consisted of five scales, including access, social structure, content, pedagogy, and community relationship toward Web-based learning. By using an online survey, this study gathered the responses of 1,866 Taiwanese university students (940 males and 926 females) whose ages ranged from 18 to 23. The results showed significant gender differences in the aspects of social structure, content, and community relationship involved in Web-based learning. Interestingly, although females might consider the Internet a masculine-dominated technology, they displayed more favorable attitudes than males did regarding the impacts of socioeconomic status (the social structure scale) on students' performance of Web-based learning. Moreover, females possessed more positive attitudes than males toward the helpfulness and variety of the content for Web learning. However, they did not think the virtual interaction on the Internet could develop adequate teacher-student and peer relationships (the community relationship scale). Some follow-up interviews were also conducted with selected students, and the implications derived from this study were discussed.

    The Internet is becoming a preferred place to find information. Millions of people go online in the search of health and medical information. Likewise, the demand for Web-based courses grows. This article presents the development, utilization and evaluation of a web-based pharmacology course for nursing students. The course was developed based on 150 commonly used drugs. There were 110 year 1 nursing students took part in the course. After attending six hours face to face lecture of pharmacology over three weeks, students were invited to complete a questionnaire (pre-test) about learning pharmacology. The course materials were then uploaded to a WebCT for student's self-directed learning and attempts to pass two scheduled online quizzes. At the end of the semester, students were given the same questionnaire (post-test). There were a significant increase in the understanding compared with memorizing the subject content, the development of problem solving ability in learning pharmacology and becoming an independent learner (p ,0.05). Online quizzes yielded satisfactory results. In the focused group interview, students appreciated the time flexibility and convenience associated with web-based learning, also, they had made good suggestions in enhancing web-based learning. Web-based approach is promising for teaching and learning pharmacology for nurses and other health-care professionals.

    Full Text Available An HMI, or Human-Machine Interface, is a software allowing users to communicate with a machine or automation system. It usually serves as a display section in SCADA (Supervisory Control and Data Acquisition system for device monitoring and control. In this papper, a 3D Web-based HMI with WebGL (Web-based Graphics Library rendering performance is presented. The main purpose of this work is to attempt to reduce the limitations of traditional 3D web HMI using the advantage of WebGL. To evaluate the performance, frame rate and frame time metrics were used. The results showed 3D Web-based HMI can maintain the frame rate 60FPS for #cube=0.5K/0.8K, 30FPS for #cube=1.1K/1.6K when it was run on Internet Explorer and Chrome respectively. Moreover, the study found that 3D Web-based HMI using WebGL contains similar frame time in each frame even though the numbers of cubes are up to 5K. This indicated stuttering incurred less in the proposed 3D Web-based HMI compared to the chosen commercial HMI product.

    This review sought to determine what is currently known about the focus, form, and efficacy of web-based interventions that aim to support the well-being of workers and enable them to manage their work-related stress. A scoping review of the literature as this relates to web-based interventions for the management of work-related stress and supporting the psychological well-being of workers was conducted. Forty-eight web-based interventions were identified and reviewed, the majority of which (n = 37) were "individual" -focused and utilized cognitive-behavioral techniques, relaxation exercises, mindfulness, or cognitive behavior therapy. Most interventions identified were provided via a website (n = 34) and were atheoretical in nature. There is some low-to-moderate quality evidence that "individual" -focused interventions are effective for supporting employee well-being and managing their work-related stress. There are few web-based interventions that target "organizational" or "individual/organization" interface factors, and there is limited support for their efficacy. A clear gap appears to exist between work-stress theory and its application in the design and development of web-based interventions for the management of work-related stress.

    Full Text Available In the paper the problem of using effective web-based technologies and tools in teaching choreography in British higher education institutions has been discussed. Researches on the usage of web-based technologies and tools for practical dance courses in choreographers’ professional training at British higher education institutions by such British scholars as L. Bracey, J. Buckroyd, J. Butterworth, B. Cohen, A. Green Gilbert, R. Lakes, L. Lavender, G. Morris, S. Popat, J. Smith-Autard, E. Warburton, D. Watson and others have been studied. The list of web-based technologies and tools used to improve the educational process, inspire and encourage both teachers and students to develop their critical thinking and reveal their potential has been presented. The most common of them have been characterized. They are: The Dance Designer, Wholodance, The Choreographer’s Notebook, Multimodal Video Annotator and DanceForms. It has been found out that one of the possible ways how to overcome the problems while incorporating web-based technologies and tools into the traditional system of education and teaching choreography, in particular, is the balanced combination of web-technologies and tools with a participative approach to teacher-student interaction. It has been concluded that web-based technologies and tools can be categorized as motivational methods appealing to students’ cognitive, emotional and behavioural engagement characterized by such attributes as innovation, easy usage and sharing, content control, motivational appeal, etc.

    The Internet has changed the way in which we gather and interpret information. Although books were once the exclusive bearers of data, knowledge is now only a keystroke away. The Internet has also facilitated the synthesis of new knowledge. Specifically, it has become a tool through which medical research is conducted. A review of the literature reveals that in the past year, over 100 medical publications have been based on Web-based survey data alone. Because of emerging Internet technologies, Web-based surveys can now be launched with little computer knowledge. They may also be self-administered, eliminating personnel requirements. Ultimately, an investigator may build, implement, and analyze survey results with speed and efficiency, obviating the need for mass mailings and data processing. All of these qualities have rendered telephone and mail-based surveys virtually obsolete. Despite these capabilities, Web-based survey techniques are not without their limitations, namely, recall and response biases. When used properly, however, Web-based surveys can greatly simplify the research process. This article discusses the implications of Web-based surveys and provides guidelines for their effective design and distribution.

    Because of the complexity of modern product design, the web-based collaborative product design aroused considerable attention of manufacturers in the last few years with the development of Internet technology. But it is still hardly achievable due to the difficulty to share product knowledge from different designers and systems. In this paper, we firstly create an ontology-based product model, which consists of PPR (Product, Process and Resource) concept models and PPR characteristic models, to describe product knowledge. Afterwards, how to represent the model in XML is discussed in detail. Then the mechanism of product knowledge collection and integration from different application systems based on interface agents is introduced. At last, a web-based open-architecture product knowledge integrating and sharing prototype system AD-HUB is developed. An example is also given and it shows that the theory discussed in this paper is efficient to represent and integrate product knowledge in web-based collaborative design processes.

    This paper presents the results of two surveys analyzing the usage of and the systems available for web-based media at European universities, and how the teachers can be motivated to increase their usage of such materials in their teaching practice. The surveys were carried out April-May 2009 among...... the EUNIS member universities and include responses from more than 30 different universities in Europe. The surveys show that 93 % of the universities have systems for supporting the use of web-based media in teaching practice, but looking at the diversity in implemented systems, no technical solution seems...... obvious. The surveys also show that many teachers are already using web-based media in their teaching practice and by addressing some of their teaching circumstances it would be possible to increase the usage even further. Based on these results the paper presents five initiatives to motivate the teachers...

    Full Text Available The purpose of this paper is to measure and compare the effectiveness of a Web-based course delivery system to a traditional course delivery system. The results indicate that a web-based course is effective and equivalent to a traditional classroom environment. As with the implementation of all new technologies, there are some pros and cons that should be considered. The significant pro is the element of convenience which eliminates the constrictive boundaries of space and time. The most notable con involves the impersonal nature of the online environment. Overall, we found the web-based course delivery system to be very successful in terms of learning outcomes and student satisfaction.

    This study examined the effects of an asynchronous Web-based supplementary learning program on the performance of nursing students' basic nursing skills. A posttest quasi-experimental design was used. Students in the intervention group (n = 62) were given login information to access the online program, while the control group (n = 99) was not. Data from both groups were collected before and 4 weeks after the intervention. An objective assessment of basic nursing skills was used to evaluate the level of skill demonstrated by the participants. Results indicate that the Web-based supplementary learning program is effective at strengthening students' basic nursing skills (P = .002). The findings also reveal that students in the intervention group showed higher-than-average satisfaction with the supplementary program (mean, 3.80 [SD, 0.81]). Thus, this Web-based program offers a learning opportunity for nursing students to enhance their skills beyond their formal lectures.

    Luaces, Miguel R.; Pedreira, Oscar; Places, Ángeles S.; Seco, Diego

    We present in this paper the architecture and some implementation details of a web-based version of a Trivial game. Our implementation achieves such a high degree of interactivity between the players that they perceive the game as being played in real-time. More importantly, no plug-in or applet is used in the architecture of the system. These properties are achieved by means of a carefully designed architecture that uses AJAX (Asynchronous JavaScript and XML) for data exchange. Using this approach, it is possible to develop any type of web-based collaborative software with few load on the web server. In the paper, we analyze traditional architectures for web-based applications and we show how our approach overcomes their limitations. Furthermore, we proof the efficiency of our approach by means of an empirical comparison.

    2001-01-01

    Full Text Available Efficient delivery of relevant product information is increasingly becoming the central basis of competition between firms. The interface design represents the central component for successful information delivery to consumers. However, interface design for web-based information systems is probably more an art than a science at this point in time. Much research is needed to understand properties of an effective interface for electronic commerce. This paper develops a framework identifying the relationship between user factors, the role of the user interface and overall system success for web-based electronic commerce. The paper argues that web-based systems for electronic commerce have some similar properties to decision support systems (DSS and adapts an established DSS framework to the electronic commerce domain. Based on a limited amount of research studying web browser interface design, the framework identifies areas of research needed and outlines possible relationships between consumer characteristics, interface design attributes and measures of overall system success.

    This paper describes a technically driven, collaborative approach to assessing the function of problem behavior using web-based technology. A case example is provided to illustrate the process used in this pilot project. A school team conducted a functional analysis with a child who demonstrated challenging behaviors in a preschool setting. Behavior analysts at a university setting provided the school team with initial workshop trainings, on-site visits, e-mail and phone communication, as well as live web-based feedback on functional analysis sessions. The school personnel implemented the functional analysis with high fidelity and scored the data reliably. Outcomes of the project suggest that there is great potential for collaboration via the use of web-based technologies for ongoing assessment and development of effective interventions. However, an empirical evaluation of this model should be conducted before wide-scale adoption is recommended.

    The objective of this study was to understand perceptions of the usability and value of web-based patient portals among parents of children with a chronic condition (diabetes, juvenile idiopathic arthritis, and cystic fibrosis). The design was a cross-sectional telephone survey with semistructured interviews and was conducted at a tertiary children's hospital. Parent ratings of their experiences with and the value of a web-based portal and reasons for not using the portal were ascertained. Most parents agreed that the portal information was accurate, timely, and useful. Confidentiality and seeing worrisome health-related information about their child was not a major concern, and parents felt that the portal helped to improve their understanding of and ability to manage their child's condition. In conclusion, the results of this study support the notion that web-based patient portals have the potential to be a useful tool for parents of children with a chronic disease.

    Moring, Camilla; Schreiber, Trine

    The paper describes and discusses a two step analysis for evaluating web based information literacy tutorials in educational practice. In a recent evaluation project the authors used the analysis to examine three web based tutorials developed by three different academic libraries in Norway. Firstly......, each web-based tutorial is analyzed as a communicative act by looking at how it argues for its purpose, how it is rhetorically organized and the interpretative repertoires used. Secondly, the tutorial is analyzed as a tool that users form opinions about while using it, and therefore the second part...... of the analysis focuses on user reception and meaning negotiation. In combination the two different analyses strengthen the evaluation of how web-tutorials as communicative acts become meaningful to users, and how this meaning is negotiated in relation to an educational practice. This approach can be recommended...

    Full Text Available According to many recent studies the effect of learning style on academic performance has been found to be significant and mismatch between teaching and learning styles causes learning failure and frustration. Thus balancing the teaching style and the students' learning style is very important. When emphasizing the individual learning processes, web-based learning offers a good opportunity for differentiating ways of learning. So far the aim of this study is to describe different learners (categorized by cognitive learning styles and their learning processes in relation to their learning outcomes and perceptions of learning experience on a web-based course. The results of the study showed that there were different kinds of learners, who utilized and experienced the learning material differently. The students varied both in their cognitive learning styles and in their learning processes, but not in the learning results, measured by grades. As an implication, some recommendations were presented for developing the web-based learning environment.

    Full Text Available The growth of communication technology in the last decade has prompted researchers to develop web based learning systems for various types of applications. The entities involved in the development of such systems are learners, instructors, system designers, administrators to name a few. With varying nature of applications and entities involved, the task of evaluating these web based learning systems appears quite challenging. The present study uses factor analysis to develop an assessment model for evaluating the web based learning systems developed by the authors. The analysis is performed on a data set derived by applying a survey instrument on a set of 140 learners using these systems. These learners ranked 20 items used for evaluation in order of their perceived degree of importance. It was found that the most important dimension was learning outcome which coincides with the general outcome of any mode of learning.

    Full Text Available With the invention of World Wide Web in 1992, delivery of distance education via internet and emergency of web-based classrooms have rapidly gained acceptance as an alternative and supplement to traditional face to face classroom instruction (Alavi, Yoo & Vogel, 1997; Rahm & Reed, 1997, which represents a paradigm shift challenging all traditionally accepted assumptions concerning dynamics of classroom management. Classroom is highly complicated environment with its features of multi-dimensionality, simultaneity, immediacy, unpredictability, publicness and history. And web based classroom is more complicated than traditional classroom because the web technology is added. Students’ views are considered by many researchers as one of the critical and valid source data in evaluating the teaching effectiveness and learning settings. The purpose of this study is to find out views of pre-service teachers about web based classroom management. With qualitative research method, particularly descriptive technique 20 pre-service teachers’ views were evaluated. Research findings revealed that students defined web-based classroom management with extra workloads of the students thus effectiveness is associated with students’ roles. Guiding/mentoring on technical issues, on the field knowledge, classroom interaction were defined by the students as the essential leadership roles of teachers. Concerning interaction while student to course content/material interaction was perceived as satisfactory, level of student to student interaction was reported as low. Web-based instruction itself and being free form time and place emerged as motivating factors. Besides, discipline is identified within the responsibility of students and accessing information without time/place limitation was perceived as advantageous side of web based classroom.

    Background Most programs addressing psychosocial concerns of cancer survivors are in-person programs that are expensive to deliver, have limited availability, and seldom deal with caregivers’ concerns. Objective This study examined the feasibility of translating an efficacious nurse-delivered program (FOCUS Program) for patients and their caregivers to a tailored, dyadic web-based format. Specific aims were to: (i) test the preliminary effects of the web-based intervention on patient and caregiver outcomes, (ii) examine participants’ program satisfaction, and (iii) determine the feasibility of using a web-based delivery format. Intervention/Methods A Phase II feasibility study was conducted with cancer patients (lung, breast, colorectal, prostate) and their family caregivers (N=38 dyads). The web-based intervention provided information and support tailored to the unique characteristics of each patient, caregiver, and their dyadic relationship. Primary outcomes were emotional distress and quality of life (QOL). Secondary outcomes were benefits of illness/caregiving, communication, support, and self-efficacy. Analyses included descriptive statistics and repeated measures ANOVA. Results Dyads had a significant decrease in emotional distress, increase in QOL, and perceived more benefits of illness/caregiving. Caregivers also had significant improvement in self-efficacy. There were no changes in communication. Participants were satisfied with program usability, but recommended additional content. Conclusions It was possible to translate a clinician-delivered program to a web-based format that was easy to use and had positive effects on dyadic outcomes. Implications for Practice The web-based program is a promising way to provide psychosocial care to more patients and caregivers using fewer personnel. It needs further testing in a larger RCT.

    Full Text Available Abstract Background Long waiting times for registration to see a doctor is problematic in China, especially in tertiary hospitals. To address this issue, a web-based appointment system was developed for the Xijing hospital. The aim of this study was to investigate the efficacy of the web-based appointment system in the registration service for outpatients. Methods Data from the web-based appointment system in Xijing hospital from January to December 2010 were collected using a stratified random sampling method, from which participants were randomly selected for a telephone interview asking for detailed information on using the system. Patients who registered through registration windows were randomly selected as a comparison group, and completed a questionnaire on-site. Results A total of 5641 patients using the online booking service were available for data analysis. Of them, 500 were randomly selected, and 369 (73.8% completed a telephone interview. Of the 500 patients using the usual queuing method who were randomly selected for inclusion in the study, responses were obtained from 463, a response rate of 92.6%. Between the two registration methods, there were significant differences in age, degree of satisfaction, and total waiting time (P P > 0.05. Being ignorant of online registration, not trusting the internet, and a lack of ability to use a computer were three main reasons given for not using the web-based appointment system. The overall proportion of non-attendance was 14.4% for those using the web-based appointment system, and the non-attendance rate was significantly different among different hospital departments, day of the week, and time of the day (P Conclusion Compared to the usual queuing method, the web-based appointment system could significantly increase patient's satisfaction with registration and reduce total waiting time effectively. However, further improvements are needed for broad use of the system.

    Discover Our Earth is a web-based system designed for classroom use, allowing access and display of geospatial data sets . It is an education and outreach module built as part of Cornell University's Geoscience Information System, originally constructed as a tool for geophysical research (http://atlas.geo.cornell.edu). Discover Our Earth has been used in university, high school and middle school classrooms. Working with real data is a powerful tool for helping students learn scientific principles, content, and the processes of scientific inquiry. In order to give students access to data that is otherwise difficult to work with, Discover Our Earth is comprised of several elements. The central component is a Java applet called QUEST (Quick Use Earth Study Tool). QUEST allows students to query and display data from three data sets selected from the 100+ housed within the Information System. Any attribute of earthquake, volcano, or topographic data can be selected and displayed, and multiple data sets can be overlain on each other, or on assorted background images (such as a geographic base map, age of the sea floor etc). Each image is saved in the QUEST history window, allowing students to compare multiple selections, or to animate a series of images as a "filmstrip." In order to help students better understand their results, the QUEST applet is supported by several other components. There are guides for both teacher and student. The student guide gives step-by-step instructions for a series of problems, and suggests others that will help students answer questions of local and global interest. The teacher guide provides background material, context, and answers to the student exercises. There are animations and 3-D visualizations that allow students to better interpret their maps. Additionally, there are interactive experiments on topics such as continental drift, isostasy, viscosity, that allow students to explore the physics that underlie the processes they are

    Background Although web-based interventions for promoting health and health-related behavior can be effective, poor adherence is a common issue that needs to be addressed. Technology as a means to communicate the content in web-based interventions has been neglected in research. Indeed, technology is often seen as a black-box, a mere tool that has no effect or value and serves only as a vehicle to deliver intervention content. In this paper we examine technology from a holistic perspective. We see it as a vital and inseparable aspect of web-based interventions to help explain and understand adherence. Objective This study aims to review the literature on web-based health interventions to investigate whether intervention characteristics and persuasive design affect adherence to a web-based intervention. Methods We conducted a systematic review of studies into web-based health interventions. Per intervention, intervention characteristics, persuasive technology elements and adherence were coded. We performed a multiple regression analysis to investigate whether these variables could predict adherence. Results We included 101 articles on 83 interventions. The typical web-based intervention is meant to be used once a week, is modular in set-up, is updated once a week, lasts for 10 weeks, includes interaction with the system and a counselor and peers on the web, includes some persuasive technology elements, and about 50% of the participants adhere to the intervention. Regarding persuasive technology, we see that primary task support elements are most commonly employed (mean 2.9 out of a possible 7.0). Dialogue support and social support are less commonly employed (mean 1.5 and 1.2 out of a possible 7.0, respectively). When comparing the interventions of the different health care areas, we find significant differences in intended usage (p = .004), setup (p persuasive technology elements, a substantial amount of variance in adherence can be explained.

    For the growing proportion of elders globally, aging-related illnesses are primary causes of morbidity causing reliance on family members for support in the community. Family caregivers experience poorer physical and mental health than their non-caregiving counterparts. Web-based interventions can provide accessible support to family caregivers to offset declines in their health and well-being. Existing reviews focused on web-based interventions for caregivers have been limited to single illness populations and have mostly focused on the efficacy of the interventions. We therefore have limited insight into how web-based interventions for family caregiver have been developed, implemented and evaluated across aging-related illness. To describe: a) theoretical underpinnings of the literature; b) development, content and delivery of web-based interventions; c) caregiver usage of web-based interventions; d) caregiver experience with web-based interventions and e) impact of web-based interventions on caregivers' health outcomes. We followed Arksey and O'Malley's methodological framework for conducting scoping reviews which entails setting research questions, selecting relevant studies, charting the data and synthesizing the results in a report. Fifty-three publications representing 32 unique web-based interventions were included. Over half of the interventions were targeted at dementia caregivers, with the rest targeting caregivers to the stroke, cancer, diabetes and general frailty populations. Studies used theory across the intervention trajectory. Interventions aimed to improve a range of health outcomes for caregivers through static and interactive delivery methods Caregivers were satisfied with the usability and accessibility of the websites but usage was generally low and declined over time. Depression and caregiver burden were the most common outcomes evaluated. The interventions ranged in their impact on health and social outcomes but reductions in perception of

    Objective long-term health monitoring can improve the clinical management of several medical conditions ranging from cardiopulmonary diseases to motor disorders. In this paper, we present our work toward the development of a home-monitoring system. The system is currently used to monitor patients with Parkinson's disease who experience severe motor fluctuations. Monitoring is achieved using wireless wearable sensors whose data are relayed to a remote clinical site via a web-based application. The work herein presented shows that wearable sensors combined with a web-based application provide reliable quantitative information that can be used for clinical decision making.

    This systematic review and meta-analysis investigated whether using web-based nursing educational programs increases a participant's knowledge and clinical performance. We performed a meta-analysis of studies published between January 2000 and July 2016 and identified through RISS, CINAHL, ProQuest Central, Embase, the Cochrane Library, and PubMed. Eleven studies were eligible for inclusion in this analysis. The results of the meta-analysis demonstrated significant differences not only for the overall effect but also specifically for blended programs and short (2 weeks or 4 weeks) intervention periods. To present more evidence supporting the effectiveness of web-based nursing educational programs, further research is warranted.

    This chapter provides an example of a Web-based support system (WSS) used to streamline trade procedures, prevent potential security threats, and reduce tax-related fraud in cross-border trade. The architecture is based on a service-oriented architecture that includes smart seals and Web services. We discuss the implications and suggest further enhancements to demonstrate how such systems can move toward a Web-based decision support system with the support of data mining methods. We provide a concrete example of how data mining can help to analyze the vast amount of data collected while monitoring the container movements along its supply chain.

    The demonstration of patient case reports in the course of a clinical round is an essential part of teaching medicine and dentistry. However, suitable live patients with particular problems are not always available at a time when teaching is taking place. This project therefore had the objective of establishing a web-based, virtual e-learning concept for demonstrating case reports independent of time and place, with the possibility of an interactive examination, diagnosis, and interdisciplinary therapy decision making for medical and dental students. Anonymized case reports of diseases in the oral and maxillofacial region and the interdisciplinary treatment were digitized and prepared in a web-based format. The technical aspect was based on connecting flash modules with videos and animation, and monitoring through HTML and Javascript. Due to the modular concept and the programming used, the learning environment was independent of platform and open. Independent formats (.swf, .avi, .mpeg, etc.) were integrated into the individual modules. According to a hierarchic decision system, the user was guided interactively to the diagnosis through a differential diagnostic exclusion process. Sound was digitized and integrated in mp3 compressed form in the 3D models for lip-synchronous speech output. The speech output was connected with a virtual 3D tutor that acted in an advisory capacity in reaching a diagnosis and determining therapy. Further sources of information and literature with abstracts or pdf files of the subject-related publications were inserted to ensure that the teaching was objective. To conclude the virtual clinical round, a check on learning success was conducted in the form of a multimedia multiple choice test.

    Patients making treatment decisions require understandable evidence-based information. However, evidence on graphical presentation of benefits and side-effects of medical treatments is not conclusive. The study evaluated a new space-saving format, CLARIFIG (clarifying risk figures), aiming to facilitate accuracy of comprehension. CLARIFIG displays groups of patients with and without treatment benefits as coloured sectors of a proportional bar graph representing in total 100 patients. Supplementary icons indicate the corresponding group's actual condition. The study used an application showing effects of immunotherapy intended to slow disease progression in multiple sclerosis (MS). In a four-arm web-based randomized controlled trial, CLARIFIG was compared to the reference standard, multifigure pictographs (MFP), regarding comprehension (primary outcome) and processing time. Both formats were presented as static and animated versions. People with MS were recruited through the website of the German MS society. Six hundred and eighty-two patients were randomized and analysed for the primary end point. There were no differences in comprehension rates (MFPstatic =46%, CLARIFIGstatic =44%; P=.59; MFPanimated =23%, CLARIFIGanimated =30%; P=.134). Processing time for CLARIFIG was shorter only in the animated version (MFPstatic =162 seconds, CLARIFIGstatic =155 seconds; P=.653; MFPanimated =286 seconds, CLARIFIGanimated =189 seconds; P≤.001). However, both animated versions caused more wrong answers and longer processing time than static presentation (MFPstatic vs animated : P≤.001/.001, CLARIFIGstatic vs animated : P=.027/.017). Comprehension of the new format is comparable to MFP. CLARIFIG has the potential to simplify presentation in more complex contexts such as comparison of several treatment options in patient decision aids, but further studies are needed. © 2016 The Authors.

    Human immune system is as important in keeping the body healthy as the brain in supporting the intelligence. However, the traditional models of the human immune system are built on the mathematics equations, which are not easy for students to understand. To help the students to understand the immune systems, a web-based e-learning approach with virtual lab is designed for the intelligent system control course by using new intelligent educational technology. Comparing the traditional graduate educational model within the classroom, the web-based e-learning with the virtual lab shows the higher inspiration in guiding the graduate students to think independently and innovatively, as the students said. It has been found that this web-based immune e-learning system with the online virtual lab is useful for teaching the graduate students to understand the immune systems in an easier way and design their simulations more creatively and cooperatively. The teaching practice shows that the optimum web-based e-learning system can be used to increase the learning effectiveness of the students.

    This paper presents a feature-rich web-based system used for biomedical education at the undergraduate level. With the powerful groupware features provided by the wiki system, the instructors are able to establish a community-centered mentoring environment that capitalizes on local expertise to create a sense of online collaborative learning among students. The web-based infrastructure can help the instructors effectively organize and coordinate student research projects, and the groupware features may support the interactive activities, such as interpersonal communications and data sharing. The groupware features also provide the web-based system with a wide range of additional ways of organizing collaboratively developed materials, which makes it become an effective tool for online active learning. Students are able to learn the ability to work effectively in teams, with an improvement of project management, design collaboration, and technical writing skills. With the fruitful outcomes in recent years, it is positively thought that the web-based collaborative learning environment can perform an excellent shift away from the conventional instructor-centered teaching to community- centered collaborative learning in the undergraduate education.
