Developing a web page: bringing clinics online.

Science.gov (United States)

Peterson, Ronnie; Berns, Susan

2004-01-01

Introducing clinical staff education, along with new policies and procedures, to over 50 different clinical sites can be a challenge. As any staff educator will confess, getting people to attend an educational inservice session can be difficult. Clinical staff request training, but no one has time to attend training sessions. Putting the training along with the policies and other information into "neat" concise packages via the computer and over the company's intranet was the way to go. However, how do you bring the clinics online when some of the clinical staff may still be reluctant to turn on their computers for anything other than to gather laboratory results? Developing an easy, fun, and accessible Web page was the answer. This article outlines the development of the first training Web page at the University of Wisconsin Medical Foundation, Madison, WI.

Upgrade of CERN OP Webtools IRRAD Page

CERN Document Server

Vik, Magnus Bjerke

2017-01-01

CERN Beams Department maintains a website with various tools for the Operations Group, with one of them being specific for the Proton Irradiation Facility (IRRAD). The IRRAD team use the tool to follow up and optimize the operation of the facility. The original version of the tool was difficult to maintain and adding new features to the page was challenging. Thus this summer student project is aimed to upgrade the web page by rewriting the web page with maintainability and flexibility in mind. The new application uses a server--client architecture with a REST API on the back end which is used by the front end to request data for visualization. PHP is used on the back end to implement the API's and Swagger is used to document them. Vue, Semantic UI, Webpack, Node and ECMAScript 5 is used on the fronted to visualize and administrate the data. The result is a new IRRAD operations web application with extended functionality, improved structure and an improved user interface. It includes a new Status Panel page th...

Using Power-Law Degree Distribution to Accelerate PageRank

Directory of Open Access Journals (Sweden)

Zhaoyan Jin

2012-12-01

Full Text Available The PageRank vector of a network is very important, for it can reflect the importance of a Web page in the World Wide Web, or of a people in a social network. However, with the growth of the World Wide Web and social networks, it needs more and more time to compute the PageRank vector of a network. In many real-world applications, the degree and PageRank distributions of these complex networks conform to the Power-Law distribution. This paper utilizes the degree distribution of a network to initialize its PageRank vector, and presents a Power-Law degree distribution accelerating algorithm of PageRank computation. Experiments on four real-world datasets show that the proposed algorithm converges more quickly than the original PageRank algorithm.

A Note on the PageRank of Undirected Graphs

OpenAIRE

2012-01-01

The PageRank is a widely used scoring function of networks in general and of the World Wide Web graph in particular. The PageRank is defined for directed graphs, but in some special cases applications for undirected graphs occur. In the literature it is widely noted that the PageRank for undirected graphs are proportional to the degrees of the vertices of the graph. We prove that statement for a particular personalization vector in the definition of the PageRank, and we also show that in gene...

How Useful are Orthopedic Surgery Residency Web Pages?

Science.gov (United States)

Oladeji, Lasun O; Yu, Jonathan C; Oladeji, Afolayan K; Ponce, Brent A

2015-01-01

Medical students interested in orthopedic surgery residency positions frequently use the Internet as a modality to gather information about individual residency programs. Students often invest a painstaking amount of time and effort in determining programs that they are interested in, and the Internet is central to this process. Numerous studies have concluded that program websites are a valuable resource for residency and fellowship applicants. The purpose of the present study was to provide an update on the web pages of academic orthopedic surgery departments in the United States and to rate their utility in providing information on quality of education, faculty and resident information, environment, and applicant information. We reviewed existing websites for the 156 departments or divisions of orthopedic surgery that are currently accredited for resident education by the Accreditation Council for Graduate Medical Education. Each website was assessed for quality of information regarding quality of education, faculty and resident information, environment, and applicant information. We noted that 152 of the 156 departments (97%) had functioning websites that could be accessed. There was high variability regarding the comprehensiveness of orthopedic residency websites. Most of the orthopedic websites provided information on conference, didactics, and resident rotations. Less than 50% of programs provided information on resident call schedules, resident or faculty research and publications, resident hometowns, or resident salary. There is a lack of consistency regarding the content presented on orthopedic residency websites. As the competition for orthopedic websites continues to increase, applicants flock to the Internet to learn more about orthopedic websites in greater number. A well-constructed website has the potential to increase the caliber of students applying to a said program. Copyright © 2015 Association of Program Directors in Surgery. Published by

Zheng, Hao; Dong, Xiaoshe; Wang, Endong; Chen, Baoke; Zhu, Zhengdong; Liu, Chengzhe

2015-01-01

With the advantage of the reusability property of the virtualization technology, users can reuse various types and versions of existing operating systems and drivers in a virtual machine, so as to customize their application environment. In order to prevent users' virtualization environments being impacted by driver faults in virtual machine, Chariot examines the correctness of driver's write operations by the method of combining a driver's write operation capture and a driver's private access control table. However, this method needs to keep the write permission of shadow page table as read-only, so as to capture isolated driver's write operations through page faults, which adversely affect the performance of the driver. Based on delaying setting frequently used shadow pages' write permissions to read-only, this paper proposes an algorithm using shadow page cache to improve the performance of isolated drivers and carefully study the relationship between the performance of drivers and the size of shadow page cache. Experimental results show that, through the shadow page cache, the performance of isolated drivers can be greatly improved without impacting Chariot's reliability too much.

In this study, the engagement of medical students on anatomy Facebook pages was evaluated in view of their academic performance. High performers contributed to most of the engagements. They also had a particular preference for higher levels of engagement. Although the students were deeply involved in the educational element of the pages, they continued to appreciate the inherent social element. The profound engagement of the high performers indicated a consistency between Facebook use in the educational context and better student performance. At the same time, the deeper engagement of high performers refutes the opinion that Facebook use is a distractor. Instead, it supports the notion that Facebook could be a suitable platform to engage students in an educational context.

Automatic Hidden-Web Table Interpretation by Sibling Page Comparison

Science.gov (United States)

Tao, Cui; Embley, David W.

The longstanding problem of automatic table interpretation still illudes us. Its solution would not only be an aid to table processing applications such as large volume table conversion, but would also be an aid in solving related problems such as information extraction and semi-structured data management. In this paper, we offer a conceptual modeling solution for the common special case in which so-called sibling pages are available. The sibling pages we consider are pages on the hidden web, commonly generated from underlying databases. We compare them to identify and connect nonvarying components (category labels) and varying components (data values). We tested our solution using more than 2,000 tables in source pages from three different domains—car advertisements, molecular biology, and geopolitical information. Experimental results show that the system can successfully identify sibling tables, generate structure patterns, interpret tables using the generated patterns, and automatically adjust the structure patterns, if necessary, as it processes a sequence of hidden-web pages. For these activities, the system was able to achieve an overall F-measure of 94.5%.

Web accessibility: a longitudinal study of college and university home pages in the northwestern United States.

Science.gov (United States)

Thompson, Terrill; Burgstahler, Sheryl; Moore, Elizabeth J

2010-01-01

This article reports on a follow-up assessment to Thompson et al. (Proceedings of The First International Conference on Technology-based Learning with Disability, July 19-20, Dayton, Ohio, USA; 2007. pp 127-136), in which higher education home pages were evaluated over a 5-year period on their accessibility to individuals with disabilities. The purpose of this article is to identify trends in web accessibility and long-term impact of outreach and education. Home pages from 127 higher education institutions in the Northwest were evaluated for accessibility three times over a 6-month period in 2004-2005 (Phase I), and again in 2009 (Phase II). Schools in the study were offered varying degrees of training and/or support on web accessibility during Phase I. Pages were evaluated for accessibility using a set of manual checkpoints developed by the researchers. Over the 5-year period reported in this article, significant positive gains in accessibility were revealed on some measures, but accessibility declined on other measures. The areas of improvement are arguably the more basic, easy-to-implement accessibility features, while the area of decline is keyboard accessibility, which is likely associated with the emergence of dynamic new technologies on web pages. Even on those measures where accessibility is improving, it is still strikingly low. In Phase I of the study, institutions that received extensive training and support were more likely than other institutions to show improved accessibility on the measures where institutions improved overall, but were equally or more likely than others to show a decline on measures where institutions showed an overall decline. In Phase II, there was no significant difference between institutions who had received support earlier in the study, and those who had not. Results suggest that growing numbers of higher education institutions in the Northwest are motivated to add basic accessibility features to their home pages, and that

Characterizing Microseismicity at the Newberry Volcano Geothermal Site using PageRank

Science.gov (United States)

Aguiar, A. C.; Myers, S. C.

2015-12-01

The Newberry Volcano, within the Deschutes National Forest in Oregon, has been designated as a candidate site for the Department of Energy's Frontier Observatory for Research in Geothermal Energy (FORGE) program. This site was stimulated using high-pressure fluid injection during the fall of 2012, which generated several hundred microseismic events. Exploring the spatial and temporal development of microseismicity is key to understanding how subsurface stimulation modifies stress, fractures rock, and increases permeability. We analyze Newberry seismicity using both surface and borehole seismometers from the AltaRock and LLNL seismic networks. For our analysis we adapt PageRank, Google's initial search algorithm, to evaluate microseismicity during the 2012 stimulation. PageRank is a measure of connectivity, where higher ranking represents highly connected windows. In seismic applications connectivity is measured by the cross correlation of 2 time windows recorded on a common seismic station and channel. Aguiar and Beroza (2014) used PageRank based on cross correlation to detect low-frequency earthquakes, which are highly repetitive but difficult to detect. We expand on this application by using PageRank to define signal-correlation topology for micro-earthquakes, including the identification of signals that are connected to the largest number of other signals. We then use this information to create signal families and compare PageRank families to the spatial and temporal proximity of associated earthquakes. Studying signal PageRank will potentially allow us to efficiently group earthquakes with similar physical characteristics, such as focal mechanisms and stress drop. Our ultimate goal is to determine whether changes in the state of stress and/or changes in the generation of subsurface fracture networks can be detected using PageRank topology. This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under

In October last year the Communication Group proposed an interim redesign of the users’ web pages in order to improve the visibility of key news items, events and announcements to the CERN community. The proposed update to the users' page (right), and the current version (left, behind) This proposed redesign was seen as a small step on the way to much wider reforms of the CERN web landscape proposed in the group’s web communication plan.   The results are available here. Some of the key points: - the balance between news / events / announcements and access to links on the users’ pages was not right - many people asked to see a reversal of the order so that links appeared first, news/events/announcements last; - many people felt that we should keep the primary function of the users’ pages as an index to other CERN websites; - many people found the sections of the front page to be poorly delineated; - people do not like scrolling; - there were performance...

Review Pages: Cities, Energy and Mobility

Gennaro Angiello

2015-12-01

Full Text Available Starting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always remaining in the groove of rigorous scientific in-depth analysis. During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it. The last section of the journal is formed by the Review Pages. They have different aims: to inform on the problems, trends and evolutionary processes; to investigate on the paths by highlighting the advanced relationships among apparently distant disciplinary fields; to explore the interaction’s areas, experiences and potential applications; to underline interactions, disciplinary developments but also, if present, defeats and setbacks. Inside the journal the Review Pages have the task of stimulating as much as possible the circulation of ideas and the discovery of new points of view. For this reason the section is founded on a series of basic’s references, required for the identification of new and more advanced interactions. These references are the research, the planning acts, the actions and the applications, analysed and investigated both for their ability to give a systematic response to questions concerning the urban and territorial planning, and for their attention to aspects such as the environmental sustainability and the innovation in the practices. For this purpose the Review Pages are formed by five sections (Web Resources; Books; Laws; Urban Practices; News and Events, each of which examines a specific aspect of the broader information storage of interest for TeMA.

Lugo-Vicente, H

2000-02-01

The Internet, the largest network of connected computers, provides immediate, dynamic, and downloadable information. By re-architecturing the work place and becoming familiar with Internet resources, pediatric surgeons have anticipated the informatics capabilities of this computer-based technology creating a new vision of work and organization in such areas as patient care, teaching, and research. This review aims to highlight how Internet navigational technology can be a useful educational resource in pediatric surgery, examines web pages of interest, and defines ideas of network communication. Basic Internet resources are electronic mail, discussion groups, file transfer, and the Worldwide Web (WWW). Electronic mailing is the most useful resource extending the avenue of learning to an international audience through news or list-servers groups. Pediatric Surgery List Server, the most popular discussion group, is a constant forum for exchange of ideas, difficult cases, consensus on management, and development of our specialty. The WWW provides an all-in-one medium of text, image, sound, and video. Associations, departments, educational sites, organizations, peer-reviewed scientific journals and Medline database web pages of prime interest to pediatric surgeons have been developing at an amazing pace. Future developments of technological advance nurturing our specialty will consist of online journals, telemedicine, international chatting, computer-based training for surgical education, and centralization of cyberspace information into database search sites.

Visual layout has a strong impact on performance and is a critical factor in the design of graphical user interfaces (GUIs) and Web pages. Many design guidelines employed in Web page design were inherited from human performance literature and GUI design studies and practices. However, few studies have investigated the more specific patterns of performance with Web pages that may reflect some differences between Web page and GUI design. We investigated interactions among four visual layout factors in Web page design (quantity of links, alignment, grouping indications, and density) in two experiments: one with pages in Hebrew, entailing right-to-left reading, and the other with English pages, entailing left-to-right reading. Some performance patterns (measured by search times and eye movements) were similar between languages. Performance was particularly poor in pages with many links and variable densities, but it improved with the presence of uniform density. Alignment was not shown to be a performance-enhancing factor. The findings are discussed in terms of the similarities and differences in the impact of layout factors between GUIs and Web pages. Actual or potential applications of this research include specific guidelines for Web page design.

In-degree and pageRank of web pages: Why do they follow similar power laws?

To evaluate the effectiveness of domain highlighting in helping users identify whether Web pages are legitimate or spurious. As a component of the URL, a domain name can be overlooked. Consequently, browsers highlight the domain name to help users identify which Web site they are visiting. Nevertheless, few studies have assessed the effectiveness of domain highlighting, and the only formal study confounded highlighting with instructions to look at the address bar. We conducted two phishing detection experiments. Experiment 1 was run online: Participants judged the legitimacy of Web pages in two phases. In Phase 1, participants were to judge the legitimacy based on any information on the Web page, whereas in Phase 2, they were to focus on the address bar. Whether the domain was highlighted was also varied. Experiment 2 was conducted similarly but with participants in a laboratory setting, which allowed tracking of fixations. Participants differentiated the legitimate and fraudulent Web pages better than chance. There was some benefit of attending to the address bar, but domain highlighting did not provide effective protection against phishing attacks. Analysis of eye-gaze fixation measures was in agreement with the task performance, but heat-map results revealed that participants' visual attention was attracted by the highlighted domains. Failure to detect many fraudulent Web pages even when the domain was highlighted implies that users lacked knowledge of Web page security cues or how to use those cues. Potential applications include development of phishing prevention training incorporating domain highlighting with other methods to help users identify phishing Web pages.

Science Education & Advocacy: Tools to Support Better Education Policies

O'Donnell, Christine; Cunningham, B.; Hehn, J. G.

2014-01-01

Education is strongly affected by federal and local policies, such as testing requirements and program funding, and many scientists and science teachers are increasingly interested in becoming more engaged with the policy process. To address this need, I worked with the American Association of Physics Teachers (AAPT) --- a professional membership society of scientists and science teachers that is dedicated to enhancing the understanding and appreciation of physics through teaching --- to create advocacy tools for its members to use, including one-page leave-behinds, guides for meeting with policymakers, and strategies for framing issues. In addition, I developed a general tutorial to aid AAPT members in developing effective advocacy strategies to support better education policies. This work was done through the Society for Physics Students (SPS) Internship program, which provides a range of opportunities for undergraduates, including research, education and public outreach, and public policy. In this presentation, I summarize these new advocacy tools and their application to astronomy education issues.

Flash-Aware Page Replacement Algorithm

Directory of Open Access Journals (Sweden)

Guangxia Xu

2014-01-01

Full Text Available Due to the limited main memory resource of consumer electronics equipped with NAND flash memory as storage device, an efficient page replacement algorithm called FAPRA is proposed for NAND flash memory in the light of its inherent characteristics. FAPRA introduces an efficient victim page selection scheme taking into account the benefit-to-cost ratio for evicting each victim page candidate and the combined recency and frequency value, as well as the erase count of the block to which each page belongs. Since the dirty victim page often contains clean data that exist in both the main memory and the NAND flash memory based storage device, FAPRA only writes the dirty data within the victim page back to the NAND flash memory based storage device in order to reduce the redundant write operations. We conduct a series of trace-driven simulations and experimental results show that our proposed FAPRA algorithm outperforms the state-of-the-art algorithms in terms of page hit ratio, the number of write operations, runtime, and the degree of wear leveling.

2014-01-01

The booming electronic books (e-books), as an extension to the paper book, are popular with readers. Recently, many efforts are put into the realistic page-turning simulation o f e-book to improve its reading experience. This paper presents a new 3D page-turning simulation approach, which employs piecewise time-dependent cylindrical surfaces to describe the turning page and constructs smooth transition method between time-dependent cylinders. The page-turning animation is produced by sequentially mapping the turning page into the cylinders with different radii and positions. Compared to the previous approaches, our method is able to imitate various effects efficiently and obtains more natural animation of turning page.

Building Interactive Simulations in Web Pages without Programming.

Science.gov (United States)

Mailen Kootsey, J; McAuley, Grant; Bernal, Julie

2005-01-01

A software system is described for building interactive simulations and other numerical calculations in Web pages. The system is based on a new Java-based software architecture named NumberLinX (NLX) that isolates each function required to build the simulation so that a library of reusable objects could be assembled. The NLX objects are integrated into a commercial Web design program for coding-free page construction. The model description is entered through a wizard-like utility program that also functions as a model editor. The complete system permits very rapid construction of interactive simulations without coding. A wide range of applications are possible with the system beyond interactive calculations, including remote data collection and processing and collaboration over a network.

PageRank of integers

Frahm, K M; Shepelyansky, D L; Chepelianskii, A D

2012-01-01

We up a directed network tracing links from a given integer to its divisors and analyze the properties of the Google matrix of this network. The PageRank vector of this matrix is computed numerically and it is shown that its probability is approximately inversely proportional to the PageRank index thus being similar to the Zipf law and the dependence established for the World Wide Web. The spectrum of the Google matrix of integers is characterized by a large gap and a relatively small number of nonzero eigenvalues. A simple semi-analytical expression for the PageRank of integers is derived that allows us to find this vector for matrices of billion size. This network provides a new PageRank order of integers.

Research of Subgraph Estimation Page Rank Algorithm for Web Page Rank

Directory of Open Access Journals (Sweden)

LI Lan-yin

2017-04-01

Full Text Available The traditional PageRank algorithm can not efficiently perform large data Webpage scheduling problem. This paper proposes an accelerated algorithm named topK-Rank，which is based on PageRank on the MapReduce platform. It can find top k nodes efficiently for a given graph without sacrificing accuracy. In order to identify top k nodes，topK-Rank algorithm prunes unnecessary nodes and edges in each iteration to dynamically construct subgraphs，and iteratively estimates lower/upper bounds of PageRank scores through subgraphs. Theoretical analysis shows that this method guarantees result exactness. Experiments show that topK-Rank algorithm can find k nodes much faster than the existing approaches.

Exploiting link structure for web page genre identification

KAUST Repository

Zhu, Jia

2015-07-07

As the World Wide Web develops at an unprecedented pace, identifying web page genre has recently attracted increasing attention because of its importance in web search. A common approach for identifying genre is to use textual features that can be extracted directly from a web page, that is, On-Page features. The extracted features are subsequently inputted into a machine learning algorithm that will perform classification. However, these approaches may be ineffective when the web page contains limited textual information (e.g., the page is full of images). In this study, we address genre identification of web pages under the aforementioned situation. We propose a framework that uses On-Page features while simultaneously considering information in neighboring pages, that is, the pages that are connected to the original page by backward and forward links. We first introduce a graph-based model called GenreSim, which selects an appropriate set of neighboring pages. We then construct a multiple classifier combination module that utilizes information from the selected neighboring pages and On-Page features to improve performance in genre identification. Experiments are conducted on well-known corpora, and favorable results indicate that our proposed framework is effective, particularly in identifying web pages with limited textual information. © 2015 The Author(s)

Artificial intelligence (AI) technology, and in particular expert systems, has shown potential applicability in many areas of operation at the Kennedy Space Center (KSC). In an era of limited resources, the early identification of good expert system applications, and their segregation from inappropriate ones can result in a more efficient use of available NASA resources. On the other hand, the education of students in a highly technical area such as AI requires an extensive hands-on effort. The nature of expert systems is such that proper sample applications for the educational process are difficult to find. A pilot project between NASA-KSC and the University of Central Florida which was designed to simultaneously address the needs of both institutions at a minimum cost. This project, referred to as Expert Systems Prototype Training Project (ESPTP), provided NASA with relatively inexpensive development of initial prototype versions of certain applications. University students likewise benefit by having expertise on a non-trivial problem accessible to them at no cost. Such expertise is indispensible in a hands-on training approach to developing expert systems.

The pages displayed by the browser are dynamically generated through interaction with a database that collects both data required for the application to work and data related to the courses provided. There are different approaches to developing applications that use databases to store information. The selected approach is based on a modular three-level architecture divided into presentation level, intermediate level, and data level. The LiveLearning platform includes modules to manage multimedia contents and to interface with the streaming server so that the student can access the training contents directly from the platform interfaces. Furthermore, the platform offers its users different modules: Teaching Units, Documents, Forums, and Chats. By appropriately combining these modules, customised training can be devised based on specific requirements. The increasing diffusion of continuous education will reduce the costs of e-learning and make this training method, which helps keep pace with technological progress, more attractive, with significant professional gains for radiologists.

2016-02-01

Facebook has been used in health research, but there is a lack of literature regarding how Facebook may be used to recruit younger adolescents. A Facebook Page was created for an adolescent cohort study on the effects of puberty hormones on well-being and behaviour in early adolescence. Used as a communication tool with existing participants, it also aimed to alert potential participants to the study. The purpose of this paper is to provide a detailed description of the development of the study Facebook Page and present the fan response to the types of posts made on the Page using the Facebook-generated Insights data. Two types of posts were made on the study Facebook Page. The first type was study-related update posts and events. The second was relevant adolescent and family research and current news posts. Observations on the use of and response to the Page were made over 1 year across three phases (phase 1, very low Facebook use; phase 2, high Facebook use; phase 3, low Facebook use). Most Page fans were female (88.6%), with the largest group of fans aged between 35 and 44 years. Study-related update posts with photographs were the most popular. This paper provides a model on which other researchers could base Facebook communication and potential recruitment in the absence of established guidelines.

Finding Specification Pages from the Web

Yoshinaga, Naoki; Torisawa, Kentaro

This paper presents a method of finding a specification page on the Web for a given object (e.g., ``Ch. d'Yquem'') and its class label (e.g., ``wine''). A specification page for an object is a Web page which gives concise attribute-value information about the object (e.g., ``county''-``Sauternes'') in well formatted structures. A simple unsupervised method using layout and symbolic decoration cues was applied to a large number of the Web pages to acquire candidate attributes for each class (e.g., ``county'' for a class ``wine''). We then filter out irrelevant words from the putative attributes through an author-aware scoring function that we called site frequency. We used the acquired attributes to select a representative specification page for a given object from the Web pages retrieved by a normal search engine. Experimental results revealed that our system greatly outperformed the normal search engine in terms of this specification retrieval.

Wikipedia is the largest online encyclopedia with over 40 million articles, and generating 500 million visits per month. The aim of this study is to assess the readability and quality of Wikipedia pages on neurosurgical related topics. We selected the neurosurgical related Wikipedia pages based on the series of online patient information articles that are published by the American Association of Neurological Surgeons (AANS). We assessed readability of Wikipedia pages using five different readability scales (Flesch Reading Ease, Flesch Kincaid Grade Level, Gunning Fog Index, SMOG) Grade level, and Coleman-Liau Index). We used the Center for Disease Control (CDC) Clear Communication Index as well as the DISCERN Instrument to evaluate the quality of each Wikipedia article. We identified a total of fifty-five Wikipedia articles that corresponded with patient information articles published by the AANS. This constitutes 77.46% of the AANS topics. The mean Flesch Kincaid reading ease score for all of the Wikipedia articles we analyzed is 31.10, which indicates that a college-level education is necessary to understand them. In comparison to the readability analysis for the AANS articles, the Wikipedia articles were more difficult to read across every scale. None of the Wikipedia articles meet the CDC criterion for clear communications. Our analyses demonstrated that Wikipedia articles related to neurosurgical topics are associated with higher grade levels for reading and also below the expected levels of clear communications for patients. Collaborative efforts from the neurosurgical community are needed to enhance the readability and quality of Wikipedia pages related to neurosurgery. Copyright © 2018 Elsevier B.V.

Face time: educating face transplant candidates.

Science.gov (United States)

Lamparello, Brooke M; Bueno, Ericka M; Diaz-Siso, Jesus Rodrigo; Sisk, Geoffroy C; Pomahac, Bohdan

2013-01-01

Face transplantation is the innovative application of microsurgery and immunology to restore appearance and function to those with severe facial disfigurements. Our group aims to establish a multidisciplinary education program that can facilitate informed consent and build a strong knowledge base in patients to enhance adherence to medication regimes, recovery, and quality of life. We analyzed handbooks from our institution's solid organ transplant programs to identify topics applicable to face transplant patients. The team identified unique features of face transplantation that warrant comprehensive patient education. We created a 181-page handbook to provide subjects interested in pursuing transplantation with a written source of information on the process and team members and to address concerns they may have. While the handbook covers a wide range of topics, it is easy to understand and visually appealing. Face transplantation has many unique aspects that must be relayed to the patients pursuing this novel therapy. Since candidates lack third-party support groups and programs, the transplant team must provide an extensive educational component to enhance this complex process. As face transplantation continues to develop, programs must create sound education programs that address patients' needs and concerns to facilitate optimal care.

PageRank centrality is used by Google for ranking web-pages to present search result for a user query. Here, we have shown that PageRank value of a vertex also depends on its intrinsic, non-network contribution. If the intrinsic, non-network contributions of the vertices are proportional to their degrees or zeros, then their PageRank centralities become proportion to their degrees. Some simulations and empirical data are used to support our study. In addition, we have shown that localization ...

Microseismic Event Relocation and Focal Mechanism Estimation Based on PageRank Linkage

Science.gov (United States)

Aguiar, A. C.; Myers, S. C.

2017-12-01

Microseismicity associated with enhanced geothermal systems (EGS) is key in understanding how subsurface stimulation can modify stress, fracture rock, and increase permeability. Large numbers of microseismic events are commonly associated with hydroshearing an EGS, making data mining methods useful in their analysis. We focus on PageRank, originally developed as Google's search engine, and subsequently adapted for use in seismology to detect low-frequency earthquakes by linking events directly and indirectly through cross-correlation (Aguiar and Beroza, 2014). We expand on this application by using PageRank to define signal-correlation topology for micro-earthquakes from the Newberry Volcano EGS in Central Oregon, which has been stimulated two times using high-pressure fluid injection. We create PageRank signal families from both data sets and compare these to the spatial and temporal proximity of associated earthquakes. PageRank families are relocated using differential travel times measured by waveform cross-correlation (CC) and the Bayesloc approach (Myers et al., 2007). Prior to relocation events are loosely clustered with events at a distance from the cluster. After relocation, event families are found to be tightly clustered. Indirect linkage of signals using PageRank is a reliable way to increase the number of events confidently determined to be similar, suggesting an efficient and effective grouping of earthquakes with similar physical characteristics (ie. location, focal mechanism, stress drop). We further explore the possibility of using PageRank families to identify events with similar relative phase polarities and estimate focal mechanisms following Shelly et al. (2016) method, where CC measurements are used to determine individual polarities within event clusters. Given a positive result, PageRank might be a useful tool in adaptive approaches to enhance production at well-instrumented geothermal sites. Prepared by LLNL under Contract DE-AC52-07NA27344

STUDENT OPINIONS ON MANAGEMENT OF DISTANCE EDUCATION APPLICATIONS

Directory of Open Access Journals (Sweden)

2014-07-01

Full Text Available Traditional education systems can sometimes become inadequate in the face of technological developments. Individuals, whose educational needs cannot be met by traditional education systems, can tend to search for alternatives and can have different demands in order to meet with these needs. These demands of the individuals can be reciprocated by managements and internet-based education methods, which remove limitations of time and space, provide facilities and equal opportunities, comply with student-centered educational approach and use computer and internet technologies, can be put into practice. Appearing before us sometimes as an alternative to the traditional education and sometimes as a support, these applications began to occupy an important place in the education systems of our era. This study, which was conducted by general survey method in view of this importance, aims to learn opinions of “masters’ students on the efficiency of distance education applications.” Survey of “Distant Education and Technologies Assessment,” developed by Aktas (2008 and adapted to Istanbul sampling by the researcher, was used in order to determine opinions. University students, who are doing masters without thesis at Social Sciences Institute Educational Administration Supervision Planning and Economics Department of Fatih University in 2013-2014 academic years, constitute the study group of the research. All of the students in the study group were reached. As a result of the study, masters’ students believe that “distance education applications” fills a very important void for individuals that experience difficulties especially in time management despite some of its inconveniencies. By looking at the results of the study, it is suggested that measures, which provide further dissemination of distance education application by will improve their technical competencies, should be taken.

The PageRank algorithm enables us to rank the nodes of a network through a specific eigenvector of the Google matrix, using a damping parameter {alpha} Element-Of ]0, 1[. Using extensive numerical simulations of large web networks, with a special accent on British University networks, we determine numerically and analytically the universal features of the PageRank vector at its emergence when {alpha} {yields} 1. The whole network can be divided into a core part and a group of invariant subspaces. For {alpha} {yields} 1, PageRank converges to a universal power-law distribution on the invariant subspaces whose size distribution also follows a universal power law. The convergence of PageRank at {alpha} {yields} 1 is controlled by eigenvalues of the core part of the Google matrix, which are extremely close to unity, leading to large relaxation times as, for example, in spin glasses.

Ren Yichao

2017-01-01

Full Text Available The information we need has some confusing problems such as dispersion and different organizational structure. In addition, because of the existence of unstructured data like natural language and images, extracting local content pages is extremely difficult. In the light of of the problems above, this article will apply a method combined with page structure analysis algorithm and page data extraction algorithm to accomplish the gathering of network data. In this way, the problem that traditional complex extraction model behave poorly when dealing with large-scale data is perfectly solved and the page data extraction efficiency is also boosted to a new level. In the meantime, the article will also make a comparison about pages and content of different types between the methods of DOM structure based on the page and HTML regularities of distribution. After all of those, we may find a more efficient extract method.

Block-accelerated aggregation multigrid for Markov chains with application to PageRank problems

Science.gov (United States)

Shen, Zhao-Li; Huang, Ting-Zhu; Carpentieri, Bruno; Wen, Chun; Gu, Xian-Ming

2018-06-01

Recently, the adaptive algebraic aggregation multigrid method has been proposed for computing stationary distributions of Markov chains. This method updates aggregates on every iterative cycle to keep high accuracies of coarse-level corrections. Accordingly, its fast convergence rate is well guaranteed, but often a large proportion of time is cost by aggregation processes. In this paper, we show that the aggregates on each level in this method can be utilized to transfer the probability equation of that level into a block linear system. Then we propose a Block-Jacobi relaxation that deals with the block system on each level to smooth error. Some theoretical analysis of this technique is presented, meanwhile it is also adapted to solve PageRank problems. The purpose of this technique is to accelerate the adaptive aggregation multigrid method and its variants for solving Markov chains and PageRank problems. It also attempts to shed some light on new solutions for making aggregation processes more cost-effective for aggregation multigrid methods. Numerical experiments are presented to illustrate the effectiveness of this technique.

Full Text Available The objective of this research was to discover the behavior of museum visitors on Facebook fan page in Indonesia based on the user motivation, user expectation, online community involvement, and Facebook fan page of the museum. This research used a quantitative approach to descriptive analysis. The population was the Facebook users who had followed the Facebook fan page of the museum in Indonesia. The samples used were 270 respondents. The researchers distributed the questionnaire to a Facebook group managed by museums or communities. Based on the demographic profile of respondent, the researchers discover that the respondents are highly educated, work as employees or student, and allocate more than Rp500.000,00 per month for traveling expense. Based on social media behavior of the respondents, the respondents are active using Facebook and not aware of the presence of museum in social media. The respondents require museum information, social interaction, and entertainment on Facebook fan page of the museum. Therefore, museum managers must maintain the content quality and perceived usefulness in delivering the information through Facebook. The involvement of cultural community can help people to get honest information about museum through credible opinion from the respondents.

Banner Pages on the New Printing Infrastructure

CERN Multimedia

2006-01-01

Changes to the printing service were announced in CERN Bulletin No. 37-38/2006. In the new infrastructure, the printing of the banner page has been disabled in order to reduce paper consumption. Statistics show that the average print job size is small and the paper savings by not printing the banner page could be up to 20 %. When each printer is moved onto the new infrastructure banner page printing will be disabled. In the case of corridor printers which are shared by several users, the Helpdesk can re-enable banner page printing upon request. We hope ultimately to arrive at a situation where banner page printing is enabled on fewer than 10% of printers registered on the network. You can still print banner pages on printers where it has been centrally disabled by using Linux. Simply add it to your print job on the client side by adding the -o job-sheets option to your lpr command.

Web-based training in German university eye hospitals - Education 2.0?

Science.gov (United States)

Handzel, Daniel M; Hesse, L

2011-01-01

To analyse web-based training in ophthalmology offered by German university eye hospitals. In January 2010 the websites of all 36 German university hospitals were searched for information provided for visitors, students and doctors alike. We evaluated the offer in terms of quantity and quality. All websites could be accessed at the time of the study. 28 pages provided information for students and doctors, one page only for students, three exclusively for doctors. Four pages didn't offer any information for these target groups. The websites offered information on events like congresses or students curricular education, there were also material for download for these events or for other purposes. We found complex e-learning-platforms on 9 pages. These dealt with special ophthalmological topics in a didactic arrangement. In spite of the extensive possibilities offered by the technology of Web 2.0, many conceivable tools were only rarely made available. It was not always possible to determine if the information provided was up-to-date, very often the last actualization of the content was long ago. On one page the date for the last change was stated as 2004. Currently there are 9 functional e-learning-applications offered by German university eye hospitals. Two additional hospitals present links to a project of the German Ophthalmological Society. There was a considerable variation in quantity and quality. No website made use of crediting successful studying, e.g. with CME-points or OSCE-credits. All German university eye hospitals present themselves in the World Wide Web. However, the lack of modern, technical as well as didactical state-of-the-art learning applications is alarming as it leaves an essential medium of today's communication unused.

PageRank without hyperlinks: Reranking with PubMed related article networks for biomedical text retrieval

Directory of Open Access Journals (Sweden)

Lin Jimmy

2008-06-01

Full Text Available Abstract Background Graph analysis algorithms such as PageRank and HITS have been successful in Web environments because they are able to extract important inter-document relationships from manually-created hyperlinks. We consider the application of these techniques to biomedical text retrieval. In the current PubMed® search interface, a MEDLINE® citation is connected to a number of related citations, which are in turn connected to other citations. Thus, a MEDLINE record represents a node in a vast content-similarity network. This article explores the hypothesis that these networks can be exploited for text retrieval, in the same manner as hyperlink graphs on the Web. Results We conducted a number of reranking experiments using the TREC 2005 genomics track test collection in which scores extracted from PageRank and HITS analysis were combined with scores returned by an off-the-shelf retrieval engine. Experiments demonstrate that incorporating PageRank scores yields significant improvements in terms of standard ranked-retrieval metrics. Conclusion The link structure of content-similarity networks can be exploited to improve the effectiveness of information retrieval systems. These results generalize the applicability of graph analysis algorithms to text retrieval in the biomedical domain.

Comparing classical and quantum PageRanks

Loke, T.; Tang, J. W.; Rodriguez, J.; Small, M.; Wang, J. B.

2017-01-01

Following recent developments in quantum PageRanking, we present a comparative analysis of discrete-time and continuous-time quantum-walk-based PageRank algorithms. Relative to classical PageRank and to different extents, the quantum measures better highlight secondary hubs and resolve ranking degeneracy among peripheral nodes for all networks we studied in this paper. For the discrete-time case, we investigated the periodic nature of the walker's probability distribution for a wide range of networks and found that the dominant period does not grow with the size of these networks. Based on this observation, we introduce a new quantum measure using the maximum probabilities of the associated walker during the first couple of periods. This is particularly important, since it leads to a quantum PageRanking scheme that is scalable with respect to network size.

The main goal of Virtual Touch is to facilitate the installation, configuration and programming of different types of technologies, abstracting the creator of educational applications from the technical details involving the use of tangible interfaces and virtual worlds. Therefore, it is specially designed to enable teachers to themselves create educational activities for their students in a simple way, taking into account that teachers generally lack advanced knowledge in computer programming and electronics. The toolkit has been used to develop various educational applications that have been tested in two secondary education high schools in Spain.

Gennaro Angiello

2014-12-01

Full Text Available Starting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always remaining in the groove of rigorous scientific in-depth analysis. During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it. The last section of the journal is formed by the Review Pages. They have different aims: to inform on the problems, trends and evolutionary processes; to investigate on the paths by highlighting the advanced relationships among apparently distant disciplinary fields; to explore the interaction’s areas, experiences and potential applications; to underline interactions, disciplinary developments but also, if present, defeats and setbacks. Inside the journal the Review Pages have the task of stimulating as much as possible the circulation of ideas and the discovery of new points of view. For this reason the section is founded on a series of basic’s references, required for the identification of new and more advanced interactions. These references are the research, the planning acts, the actions and the applications, analysed and investigated both for their ability to give a systematic response to questions concerning the urban and territorial planning, and for their attention to aspects such as the environmental sustainability and the innovation in the practices. For this purpose the Review Pages are formed by five sections (Web Resources; Books; Laws; Urban Practices; News and Events, each of which examines a specific aspect of the broader information storage of interest for TeMA.

As technology advances, mobile devices have gradually turned into wearable devices. Furthermore, virtual reality (VR), augmented reality (AR), and mixed reality (MR) are being increasingly applied in medical fields such as medical education and training, surgical simulation, neurological rehabilitation, psychotherapy, and telemedicine. Research results demonstrate the ability of VR, AR, and MR to ameliorate the inconveniences that are often associated with traditional medical care, reduce incidents of medical malpractice caused by unskilled operations, and reduce the cost of medical education and training. What is more, the application of these technologies has enhanced the effectiveness of medical education and training, raised the level of diagnosis and treatment, improved the doctor-patient relationship, and boosted the efficiency of medical execution. The present study introduces VR, AR, and MR applications in medical practice and education with the aim of helping health professionals better understand the applications and use these technologies to improve the quality of medical care.

An Improved Approach to the PageRank Problems

2013-01-01

Full Text Available We introduce a partition of the web pages particularly suited to the PageRank problems in which the web link graph has a nested block structure. Based on the partition of the web pages, dangling nodes, common nodes, and general nodes, the hyperlink matrix can be reordered to be a more simple block structure. Then based on the parallel computation method, we propose an algorithm for the PageRank problems. In this algorithm, the dimension of the linear system becomes smaller, and the vector for general nodes in each block can be calculated separately in every iteration. Numerical experiments show that this approach speeds up the computation of PageRank.

Klein, David; Myhill, William; Hansen, Linda; Asby, Gary; Michaelson, Susan; Blanck, Peter

2003-01-01

The Americans with Disabilities Act (ADA), and Sections 504 and 508 of the Rehabilitation Act, prohibit discrimination against people with disabilities in all aspects of daily life, including education, work, and access to places of public accommodations. Increasingly, these antidiscrimination laws are used by persons with disabilities to ensure equal access to e-commerce, and to private and public Internet websites. To help assess the impact of the anti-discrimination mandate for educational communities, this study examined 157 website home pages of Iowa public high schools (52% of high schools in Iowa) in terms of their electronic accessibility for persons with disabilities. We predicted that accessibility problems would limit students and others in obtaining information from the web pages as well as limiting ability to navigate to other web pages. Findings show that although many web pages examined included information in accessible formats, none of the home pages met World Wide Web Consortium (W3C) standards for accessibility. The most frequent accessibility problem was lack of alternative text (ALT tags) for graphics. Technical sophistication built into pages was found to reduce accessibility. Implications are discussed for schools and educational institutions, and for laws, policies, and procedures on website accessibility. Copyright 2003 John Wiley & Sons, Ltd.

Internal medicine resident physicians were surveyed before the launch of a residency-specific Twitter webpage on August 1, 2013, and again 135 days later, to determine their use of the Twitter application and web page, as well as other social media for medical education. Residents at an internal medicine urban academic training program. All residents within our training program were administered web-based surveys. The surveys assessed resident views and their frequency of use of social media for medical education purposes, and consisted of 10 Likert scale questions. Each answer consisted of a datapoint on a 1-5 scale (1=not useful, 3=useful, 5=very useful). The final survey question was open-ended and asked for general comments. Thirty-five of 50 residents (70%) completed the presurvey and 40 (80%) participated in the postsurvey. At baseline, 34 out of 35 residents used social media and nine specifically used Twitter. Twenty-seven (77%) used social media for medical education; however, only three used Twitter for educational purposes. After the establishment of the Twitter page, the percentage of residents using social media for educational purposes increased (34 of 40 residents, 85%), and 22 used Twitter for this purpose (pmedia could be useful as a medical education tool, which slightly increased from 30 out of 35 in the preintervention survey (p=0.01). Residents believe social media could be used for medical education. After we launched a Twitter page

Uniform Page Migration Problem in Euclidean Space

Directory of Open Access Journals (Sweden)

Amanj Khorramian

2016-08-01

Full Text Available The page migration problem in Euclidean space is revisited. In this problem, online requests occur at any location to access a single page located at a server. Every request must be served, and the server has the choice to migrate from its current location to a new location in space. Each service costs the Euclidean distance between the server and request. A migration costs the distance between the former and the new server location, multiplied by the page size. We study the problem in the uniform model, in which the page has size D = 1 . All request locations are not known in advance; however, they are sequentially presented in an online fashion. We design a 2.75 -competitive online algorithm that improves the current best upper bound for the problem with the unit page size. We also provide a lower bound of 2.732 for our algorithm. It was already known that 2.5 is a lower bound for this problem.

2015-08-01

Full Text Available In this paper, we present Virtual Touch, a toolkit that allows the development of educational activities through a mixed reality environment such that, using various tangible elements, the interconnection of a virtual world with the real world is enabled. The main goal of Virtual Touch is to facilitate the installation, configuration and programming of different types of technologies, abstracting the creator of educational applications from the technical details involving the use of tangible interfaces and virtual worlds. Therefore, it is specially designed to enable teachers to themselves create educational activities for their students in a simple way, taking into account that teachers generally lack advanced knowledge in computer programming and electronics. The toolkit has been used to develop various educational applications that have been tested in two secondary education high schools in Spain.

PageRank for low frequency earthquake detection

Science.gov (United States)

Aguiar, A. C.; Beroza, G. C.

2013-12-01

We have analyzed Hi-Net seismic waveform data during the April 2006 tremor episode in the Nankai Trough in SW Japan using the autocorrelation approach of Brown et al. (2008), which detects low frequency earthquakes (LFEs) based on pair-wise waveform matching. We have generalized this to exploit the fact that waveforms may repeat multiple times, on more than just a pair-wise basis. We are working towards developing a sound statistical basis for event detection, but that is complicated by two factors. First, the statistical behavior of the autocorrelations varies between stations. Analyzing one station at a time assures that the detection threshold will only depend on the station being analyzed. Second, the positive detections do not satisfy "closure." That is, if window A correlates with window B, and window B correlates with window C, then window A and window C do not necessarily correlate with one another. We want to evaluate whether or not a linked set of windows are correlated due to chance. To do this, we map our problem on to one that has previously been solved for web search, and apply Google's PageRank algorithm. PageRank is the probability of a 'random surfer' to visit a particular web page; it assigns a ranking for a webpage based on the amount of links associated with that page. For windows of seismic data instead of webpages, the windows with high probabilities suggest likely LFE signals. Once identified, we stack the matched windows to improve the snr and use these stacks as template signals to find other LFEs within continuous data. We compare the results among stations and declare a detection if they are found in a statistically significant number of stations, based on multinomial statistics. We compare our detections using the single-station method to detections found by Shelly et al. (2007) for the April 2006 tremor sequence in Shikoku, Japan. We find strong similarity between the results, as well as many new detections that were not found using

Metadata Schema Used in OCLC Sampled Web Pages

Directory of Open Access Journals (Sweden)

Fei Yu

2005-12-01

Full Text Available The tremendous growth of Web resources has made information organization and retrieval more and more difficult. As one approach to this problem, metadata schemas have been developed to characterize Web resources. However, many questions have been raised about the use of metadata schemas such as which metadata schemas have been used on the Web? How did they describe Web accessible information? What is the distribution of these metadata schemas among Web pages? Do certain schemas dominate the others? To address these issues, this study analyzed 16,383 Web pages with meta tags extracted from 200,000 OCLC sampled Web pages in 2000. It found that only 8.19% Web pages used meta tags; description tags, keyword tags, and Dublin Core tags were the only three schemas used in the Web pages. This article revealed the use of meta tags in terms of their function distribution, syntax characteristics, granularity of the Web pages, and the length distribution and word number distribution of both description and keywords tags.

Matthew F. Pollard

2012-04-01

Full Text Available BackgroundThe use of electronic resources in education, including i-applications used on portable handheld devices, is increasing. Apple® handheld devices are popular, with free applications the most prevalent download form. Many gross anatomy i-applications are available, however no information on the quality of free anatomy products is available. Rating such products could therefore guide product recommendations.AimTo evaluate the quality and range of free iPod® applications that are applicable for tertiary level gross anatomy education.MethodsA search of the iTunes® Application Store with keywords anatomy, free, medical, functional, clinical, gross, and human was performed, with inclusion based on free applications containing human gross anatomy usable for tertiary education purposes. Application specification was noted; each was trialled independently and rated for usability, specification, academic level, and quality (image and programme.ResultsSixty-three applications were identified and eleven met inclusion criteria. Two provided gross anatomy of the entire body, nine examined specific regions or systems. Five were judged introductory in academic level, five intermediate, and one advanced. One application was rated low quality, and four excellent. None were considered difficult to use (six easy, five medium. Application size ranged between 1.2MB and 229MB (mean 27MB.ConclusionsThere are few free i-applications for learning gross anatomy and most concentrate on individual body systems, with the academic level and usability of all products well rated. Results suggest some free I-applications could be suitable adjuncts for gross anatomy education at both an undergraduate and graduate level.

Page Recognition: Quantum Leap In Recognition Technology

Science.gov (United States)

Miller, Larry

1989-07-01

No milestone has proven as elusive as the always-approaching "year of the LAN," but the "year of the scanner" might claim the silver medal. Desktop scanners have been around almost as long as personal computers. And everyone thinks they are used for obvious desktop-publishing and business tasks like scanning business documents, magazine articles and other pages, and translating those words into files your computer understands. But, until now, the reality fell far short of the promise. Because it's true that scanners deliver an accurate image of the page to your computer, but the software to recognize this text has been woefully disappointing. Old optical-character recognition (OCR) software recognized such a limited range of pages as to be virtually useless to real users. (For example, one OCR vendor specified 12-point Courier font from an IBM Selectric typewriter: the same font in 10-point, or from a Diablo printer, was unrecognizable!) Computer dealers have told me the chasm between OCR expectations and reality is so broad and deep that nine out of ten prospects leave their stores in disgust when they learn the limitations. And this is a very important, very unfortunate gap. Because the promise of recognition -- what people want it to do -- carries with it tremendous improvements in our productivity and ability to get tons of written documents into our computers where we can do real work with it. The good news is that a revolutionary new development effort has led to the new technology of "page recognition," which actually does deliver the promise we've always wanted from OCR. I'm sure every reader appreciates the breakthrough represented by the laser printer and page-makeup software, a combination so powerful it created new reasons for buying a computer. A similar breakthrough is happening right now in page recognition: the Macintosh (and, I must admit, other personal computers) equipped with a moderately priced scanner and OmniPage software (from Caere

The content of this project focuses on designing and implementing a new prototype website for the Kennedy Intern Tracking System (KITS). The goal of the new website is to allow the user to search for interns based on several different categories and fields. In hence, making it easier to find a count of interns matching a set of criteria. The KSC office of education is the primary users of KITS, their job is to recruit interns year-round. As a secondary goal, each user will be able to generate a report of their searches onto a portable document format (PDF) me. The results of each search will be set to a limited amount per page. This site will be used for Kennedy Space Center internal purposes only. After the implementations are done, a visual walk through using screen shots will be used to guide the users through all of the different scenarios that are likely to occur when the users are navigating through the site. In addition, a demo of the site will be presented to the KSC Office of Education. JavaScript and JQuery are the languages that will focus on the functionality of the implementation. Hyper Text Markup Language will be used to form the foundation for the body structure of the website. Ruby will be the programming language used to elevate the prototype to a dynamic website and enable the programmer to finish with in an efficient time frame. Cascading Style Sheet will be the language used for the design and styling purposes. Rails is the framework that the new website will be built upon.

Neuroscience: viable applications in education?

Science.gov (United States)

Devonshire, Ian M; Dommett, Eleanor J

2010-08-01

As a relatively young science, neuroscience is still finding its feet in potential collaborations with other disciplines. One such discipline is education, with the field of neuroeducation being on the horizon since the 1960s. However, although its achievements are now growing, the partnership has not been as successful as first hopes suggested it should be. Here the authors discuss the theoretical barriers and potential solutions to this, which have been suggested previously, with particular focus on levels of research in neuroscience and their applicability to education. Moreover, they propose that these theoretical barriers are driven and maintained by practical barriers surrounding common language and research literacy. They propose that by overcoming these practical barriers through appropriate training and shared experience, neuroeducation can reach its full potential.

The aim of this study was to examine the potential of a self-designed Facebook page on Neuroscience, to supplement in-class teaching as a mode of blended learning. Posts were split into multiple choice questions (MCQs), general interest articles, neuroscience-related external links and resources, and lecture notes and PowerPoint presentations. The study was divided into three distinct phases: before, during, and after the Neuroscience block. Student responses were evaluated via a self-developed questionnaire. Grades achieved by students undertaking the block in 2015 and 2014 were recorded, as were the grades achieved by the same cohort in concurrent blocks in the same year of study. Results showed that ~80% of students reported that use of the page enhanced their overall subject knowledge and exam preparation. Highest page activity occurred during the Neuroscience block. Peak activity occurred directly before summative assessments, with MCQ posts having the highest impact. The cohort of students with access to the Facebook page achieved better grades in the block compared with the previous cohort, despite similar average performance in other subjects. We demonstrate the utility of Facebook as a powerful tool for undergraduate education, supplementing in-class teaching, and assisting in exam preparation, potentially increasing average student performance.

2016-10-01

Alzheimer's disease (AD) is the fourth leading cause of death in Puerto Rico. Using multi-media resources and in-person education may be an effective approach to improve knowledge and awareness of AD. The Un Café por el Alzheimer program in Puerto Rico incorporates an education component at coffee shops and a social media campaign using Facebook. The current study evaluates this initiative through an analysis of pre/post education survey results and social media content and use. Surveys contained close-ended and open-ended questions to understand participants' perceptions and knowledge about AD. Post-education surveys also included questions related to program satisfaction. Social media analysis of the Facebook community page examined posts from March 1 to September 30, 2015. Descriptive statistics were used to analyze survey and Facebook data. Four education sessions were conducted with a total of 212 participants. Fifty-one of the participants completed both pre- and post-surveys. Following the education program participants reported improved knowledge of risk and protective factors. All participants reported learning new information from the program. There were a total of 250 posts on the Un Café por el Alzheimer community Facebook page; 168 posts related to AD. The Facebook page reached 294,109 people, with 9963 page likes, 610 comments, 17,780 post clicks, and 3632 shares. There was an average increase of 64.8 % in number of people reached by the Facebook page following the education sessions. The approach of combining social media resources and in-person education is beneficial to increase public awareness of AD and disseminate health information.

An Adaptive Reordered Method for Computing PageRank

Directory of Open Access Journals (Sweden)

Yi-Ming Bu

2013-01-01

Full Text Available We propose an adaptive reordered method to deal with the PageRank problem. It has been shown that one can reorder the hyperlink matrix of PageRank problem to calculate a reduced system and get the full PageRank vector through forward substitutions. This method can provide a speedup for calculating the PageRank vector. We observe that in the existing reordered method, the cost of the recursively reordering procedure could offset the computational reduction brought by minimizing the dimension of linear system. With this observation, we introduce an adaptive reordered method to accelerate the total calculation, in which we terminate the reordering procedure appropriately instead of reordering to the end. Numerical experiments show the effectiveness of this adaptive reordered method.

Methodology of development and students' perceptions of a psychiatry educational smartphone application.

Science.gov (United States)

Zhang, Melvyn W B; Ho, Cyrus S H; Ho, Roger C M

2014-01-01

The usage of Smartphones and smartphone applications in the recent decade has indeed become more prevalent. Previous research has highlighted the lack of critical appraisal of new applications. In addition, previous research has highlighted a method of using just the Internet Browser and a text editor to create an application, but this does not eliminate the challenges faced by clinicians. In addition, even though there has been a high rate of smartphone applications usage and acceptance, it is common knowledge that it would cost clinicians as well as their centers a lot to develop smartphone applications that could be catered to their needs, and help them in their daily educational needs. The objectives of the current research are thus to highlight a cost-effective methodology of development of interactive education smartphone applications, and also to determine whether medical students are receptive towards having smartphone applications and their perspectives with regards to the contents within. In this study, we will elaborate how the Mastering Psychiatry Online Portal and web-based mobile application were developed using HTML5 as the core programming language. The online portal and web-based application was launched in July 2012 and usage data were obtained. Subsequently, a native application was developed, as it was funded by an educational grant and students are recruited after their end of posting clinical examination to fill up a survey questionnaire relating to perspectives. Our initial analytical results showed that since inception to date, for the online portal, there have been a total of 15,803 views, with a total of 2,109 copies of the online textbook being downloaded. As for the online videos, 5,895 viewers have watched the training videos from the start till the end. 722 users have accessed the mobile textbook application. A total of 185 students participated in the perspective survey, with the majority having positive perspectives about the

Functional Multiplex PageRank

Iacovacci, Jacopo; Rahmede, Christoph; Arenas, Alex; Bianconi, Ginestra

2016-10-01

Recently it has been recognized that many complex social, technological and biological networks have a multilayer nature and can be described by multiplex networks. Multiplex networks are formed by a set of nodes connected by links having different connotations forming the different layers of the multiplex. Characterizing the centrality of the nodes in a multiplex network is a challenging task since the centrality of the node naturally depends on the importance associated to links of a certain type. Here we propose to assign to each node of a multiplex network a centrality called Functional Multiplex PageRank that is a function of the weights given to every different pattern of connections (multilinks) existent in the multiplex network between any two nodes. Since multilinks distinguish all the possible ways in which the links in different layers can overlap, the Functional Multiplex PageRank can describe important non-linear effects when large relevance or small relevance is assigned to multilinks with overlap. Here we apply the Functional Page Rank to the multiplex airport networks, to the neuronal network of the nematode C. elegans, and to social collaboration and citation networks between scientists. This analysis reveals important differences existing between the most central nodes of these networks, and the correlations between their so-called pattern to success.

With the rapid development of the World Wide Web, people benefit more and more from the sharing of information. However, Web pages with obscene, harmful, or illegal content can be easily accessed. It is important to recognize such unsuitable, offensive, or pornographic Web pages. In this paper, a novel framework for recognizing pornographic Web pages is described. A C4.5 decision tree is used to divide Web pages, according to content representations, into continuous text pages, discrete text pages, and image pages. These three categories of Web pages are handled, respectively, by a continuous text classifier, a discrete text classifier, and an algorithm that fuses the results from the image classifier and the discrete text classifier. In the continuous text classifier, statistical and semantic features are used to recognize pornographic texts. In the discrete text classifier, the naive Bayes rule is used to calculate the probability that a discrete text is pornographic. In the image classifier, the object's contour-based features are extracted to recognize pornographic images. In the text and image fusion algorithm, the Bayes theory is used to combine the recognition results from images and texts. Experimental results demonstrate that the continuous text classifier outperforms the traditional keyword-statistics-based classifier, the contour-based image classifier outperforms the traditional skin-region-based image classifier, the results obtained by our fusion algorithm outperform those by either of the individual classifiers, and our framework can be adapted to different categories of Web pages.

WebScore: An Effective Page Scoring Approach for Uncertain Web Social Networks

Directory of Open Access Journals (Sweden)

Shaojie Qiao

2011-10-01

Full Text Available To effectively score pages with uncertainty in web social networks, we first proposed a new concept called transition probability matrix and formally defined the uncertainty in web social networks. Second, we proposed a hybrid page scoring algorithm, called WebScore, based on the PageRank algorithm and three centrality measures including degree, betweenness, and closeness. Particularly,WebScore takes into a full consideration of the uncertainty of web social networks by computing the transition probability from one page to another. The basic idea ofWebScore is to: (1 integrate uncertainty into PageRank in order to accurately rank pages, and (2 apply the centrality measures to calculate the importance of pages in web social networks. In order to verify the performance of WebScore, we developed a web social network analysis system which can partition web pages into distinct groups and score them in an effective fashion. Finally, we conducted extensive experiments on real data and the results show that WebScore is effective at scoring uncertain pages with less time deficiency than PageRank and centrality measures based page scoring algorithms.

Galiatsatos, Panagis; Porto-Carreiro, Fernanda; Hayashi, Jennifer; Zakaria, Sammy; Christmas, Colleen

2016-01-01

Background Residents work at variable times and are often unable to attend all scheduled educational sessions. Therefore, new asynchronistic approaches to learning are essential in ensuring exposure to a comprehensive education. Social media tools may be especially useful, because they are accessed at times convenient for the learner. Objective Assess if the use of Twitter for medical education impacts the attitude and behavior of residents toward using social media for medical education. Design Preintervention and postintervention surveys. Internal medicine resident physicians were surveyed before the launch of a residency-specific Twitter webpage on August 1, 2013, and again 135 days later, to determine their use of the Twitter application and web page, as well as other social media for medical education. Participants Residents at an internal medicine urban academic training program. Main Measures All residents within our training program were administered web-based surveys. The surveys assessed resident views and their frequency of use of social media for medical education purposes, and consisted of 10 Likert scale questions. Each answer consisted of a datapoint on a 1–5 scale (1=not useful, 3=useful, 5=very useful). The final survey question was open-ended and asked for general comments. Key Results Thirty-five of 50 residents (70%) completed the presurvey and 40 (80%) participated in the postsurvey. At baseline, 34 out of 35 residents used social media and nine specifically used Twitter. Twenty-seven (77%) used social media for medical education; however, only three used Twitter for educational purposes. After the establishment of the Twitter page, the percentage of residents using social media for educational purposes increased (34 of 40 residents, 85%), and 22 used Twitter for this purpose (pincreased from 11.4 to 60.0% (psocial media could be useful as a medical education tool, which slightly increased from 30 out of 35 in the preintervention survey (p=0

Grahame, Michael; Laberge, Jason; Scialfa, Charles T

2004-01-01

Reaction time, eye movements, and errors were measured during visual search of Web pages to determine age-related differences in performance as a function of link size, link number, link location, and clutter. Participants (15 young adults, M = 23 years; 14 older adults, M = 57 years) searched Web pages for target links that varied from trial to trial. During one half of the trials, links were enlarged from 10-point to 12-point font. Target location was distributed among the left, center, and bottom portions of the screen. Clutter was manipulated according to the percentage of used space, including graphics and text, and the number of potentially distracting nontarget links was varied. Increased link size improved performance, whereas increased clutter and links hampered search, especially for older adults. Results also showed that links located in the left region of the page were found most easily. Actual or potential applications of this research include Web site design to increase usability, particularly for older adults.

Page Oriented Holographic Memories And Optical Pattern Recognition

Science.gov (United States)

Caulfield, H. J.

1987-08-01

In the twenty-two years since VanderLugt's introduction of holographic matched filtering, the intensive research carried out throughout the world has led to no applications in complex environment. This leads one to the suspicion that the VanderLugt filter technique is insufficiently complex to handle truly complex problems. Therefore, it is of great interest to increase the complexity of the VanderLugt filtering operation. We introduce here an approach to the real time filter assembly: use of page oriented holographic memories and optically addressed SLMs to achieve intelligent and fast reprogramming of the filters using a 10 4 to 10 6 stored pattern base.

No Hawking-Page phase transition in three dimensions

International Nuclear Information System (INIS)

Myung, Y.S.

2005-01-01

We investigate whether or not the Hawking-Page phase transition is possible to occur in three dimensions. Starting with the simplest class of Lanczos-Lovelock action, thermodynamic behavior of all AdS-type black holes without charge falls into two classes: Schwarzschild-AdS black holes in even dimensions and Chern-Simons black holes in odd dimensions. The former class can provide the Hawking-Page transition between Schwarzschild-AdS black holes and thermal AdS space. On the other hand, the latter class is exceptional and thus the Hawking-Page transition is hard to occur. In three dimensions, a second-order phase transition might occur between the non-rotating BTZ black hole and the massless BTZ black hole (thermal AdS space), instead of the first-order Hawking-Page transition between the non-rotating BTZ black hole and thermal AdS space

Application of Learning Theories on Medical Imaging Education

Directory of Open Access Journals (Sweden)

Osama A. Mabrouk Kheiralla

2018-05-01

Full Text Available The main objective of the education process is that student must learn well rather than the educators to teach well. If radiologists get involved in the process of medical education, it is important for them to do it through sound knowledge of how students learn. Researches have proved that most of the teachers in the field of medical education including diagnostic imaging are actually doctors or technicians, who didn’t have an opportunity to study the basics of learning. Mostly they have gained their knowledge through watching other educators, and they mostly rely on their personal skills and experience in doing their job. This will hinder them from conveying knowledge in an effective and scientific way, and they will find themselves lagging away behind the latest advances in the field of medical education and educational research, which will lead to negative cognitive outcomes among learners. This article presents an overview of three of the most influential basic theories of learning, upon which many teachers rely in their practical applications, which must be considered by radiologist who act as medical educators.

Complementing anatomy education using three-dimensional anatomy mobile software applications on tablet computers.

Science.gov (United States)

Lewis, T L; Burnett, B; Tunstall, R G; Abrahams, P H

2014-04-01

Anatomy has traditionally been a cornerstone of medical education, which has been taught via dissection and didactic lectures. The rising prevalence of mobile tablet technology means medical software applications ("apps") play an increasingly important role in medical education. The applications highlighted in this article will aid anatomical educators to identify which are the most useful in clinical, academic, and educational environments. These have been systematically identified by downloading all applications with keywords related to anatomy and then carrying out qualitative assessment. Novel anatomy applications from developers such as Visible Body, 3D4Medical, and Pocket Anatomy allow students to visualize and manipulate complex anatomical structures using detailed 3D models. They often contain additional content including clinical correlations and a range of media from instructional videos to interactive quiz functions. The strength of tablet technology lies in its ability to consolidate and present anatomical information to the user in the most appropriate manner for their learning style. The only question mark remains over the level of detail and accuracy of these applications. Innovative medical educators who embrace tablet technology will find that anatomy applications serve as a useful learning tool when used in conjunction with existing teaching setups.

Representin' in cyberspace: sexual scripts, self-definition, and hip hop culture in Black American adolescent girls' home pages.

Science.gov (United States)

Stokes, Carla E

2007-01-01

Despite the importance of media in the lives of girls, sexuality researchers have largely overlooked how Black American adolescent girls engage with media to construct sexual self-definitions and explore their emerging sexuality. This study investigated sexual scripts, self-definition, and hip hop culture in internet home pages constructed by Black girls aged 14-17 years residing in southern states in the USA. Although some girls in the sample constructed sexual self-representations that mirrored sexual scripts portrayed in the media, hip hop, and youth cyberculture, others resisted stereotypical representations of Black female sexuality. This paper discusses the dominant sexual scripts that emerged from in-depth analysis of 27 home pages constructed by girls residing in Georgia. The focus is on 'Freaks', 'Virgins', 'Down-Ass Chicks/Bitches', 'Pimpettes', and Resisters. Findings suggest that a one-size-fits-all approach to sexuality education may fail to address key contextual issues of relevance to girls and young women. Innovative sexuality and media education strategies that respond to the significance of media in the lives of Black American girls and young women are needed.

Gennaro Angiello

2016-12-01

Full Text Available Starting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always remaining in the groove of rigorous scientific in-depth analysis. During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it. The last section of the journal is formed by the Review Pages. They have different aims: to inform on the problems, trends and evolutionary processes; to investigate on the paths by highlighting the advanced relationships among apparently distant disciplinary fields; to explore the interaction’s areas, experiences and potential applications; to underline interactions, disciplinary developments but also, if present, defeats and setbacks. Inside the journal the Review Pages have the task of stimulating as much as possible the circulation of ideas and the discovery of new points of view. For this reason the section is founded on a series of basic’s references, required for the identification of new and more advanced interactions. These references are the research, the planning acts, the actions and the applications, analysed and investigated both for their ability to give a systematic response to questions concerning the urban and territorial planning, and for their attention to aspects such as the environmental sustainability and the innovation in the practices. For this purpose the Review Pages are formed by five sections (Web Resources; Books; Laws; Urban Practices; News and Events, each of which examines a specific aspect of the broader information storage of interest for TeMA.

O'Donovan, Peter; Agarwala, Aseem; Hertzmann, Aaron

2014-08-01

This paper presents an approach for automatically creating graphic design layouts using a new energy-based model derived from design principles. The model includes several new algorithms for analyzing graphic designs, including the prediction of perceived importance, alignment detection, and hierarchical segmentation. Given the model, we use optimization to synthesize new layouts for a variety of single-page graphic designs. Model parameters are learned with Nonlinear Inverse Optimization (NIO) from a small number of example layouts. To demonstrate our approach, we show results for applications including generating design layouts in various styles, retargeting designs to new sizes, and improving existing designs. We also compare our automatic results with designs created using crowdsourcing and show that our approach performs slightly better than novice designers.

Much has been written about the pros and cons of column-orientation as a means to speed up read-mostly analytic workloads in relational databases. In this paper we try to dissect the primitive mechanisms of a database that help express the coherence of tuples and present a novel way of organizing relational data in order to exploit the advantages of both, the row-oriented and the column-oriented world. As we go, we break with yet another bad habit of databases, namely the equal granularity of reads and writes which leads us to the introduction of consecutive clusters of disk pages called super-pages.

2011-02-01

Enormous and constantly increasing quantity of biological information is represented in metabolic and in protein interaction network databases. Most of these data are freely accessible through large public depositories. The robust analysis of these resources needs novel technologies, being developed today. Here we demonstrate a technique, originating from the PageRank computation for the World Wide Web, for analyzing large interaction networks. The method is fast, scalable and robust, and its capabilities are demonstrated on metabolic network data of the tuberculosis bacterium and the proteomics analysis of the blood of melanoma patients. The Perl script for computing the personalized PageRank in protein networks is available for non-profit research applications (together with sample input files) at the address: http://uratim.com/pp.zip.

The key words were “comparative effectiveness research,” “education,” “patient outcomes,” “effectiveness,” “cost-effectiveness,” and “efficiency.” All selected literatures were initially scrutinized by the principal investigator in terms of scientific rigor and then synthesized on an ongoing basis. CER methodologies in nursing research were presented to be significant in terms of enabling the distinctiveness of the nursing profession to stand out. Three CER methodologies applicable to nursing research—a Pragmatic Clinical Trial, Observational Comparative Effectiveness Research and Cost Effectiveness Research—revealed each of their distinguishable strengths and weaknesses compared to the Randomized Controlled Trial. For ethical considerations, the importance of ensuring “equipoise” was identified. Lastly, in a head to head comparison of two nursing education programs, a single blind, randomized crossover study design was proposed as a type of Pragmatic Clinical Trial utilizing cost-utility analysis. A mixed method Analysis of Covariance and a Doubly Multivariate Repeated Analysis of Covariance were suggested as relevant statistical analyses. Considering that CER is still inchoate in nursing research and nurse scientists’ endeavors to address the gap are urgent, this study is compelling in that it proposed a rigorous CER design not only directly applicable to nursing education, but also to other disciplines in education.

We show that in order to determine the Google PageRank for

Enhancing the Ranking of a Web Page in the Ocean of Data

2013-10-01

Full Text Available In today's world, web is considered as ocean of data and information (like text, videos, multimedia etc. consisting of millions and millions of web pages in which web pages are linked with each other like a tree. It is often argued that, especially considering the dynamic of the internet, too much time has passed since the scientific work on PageRank, as that it still could be the basis for the ranking methods of the Google search engine. There is no doubt that within the past years most likely many changes, adjustments and modifications regarding the ranking methods of Google have taken place, but PageRank was absolutely crucial for Google's success, so that at least the fundamental concept behind PageRank should still be constitutive. This paper describes the components which affects the ranking of the web pages and helps in increasing the popularity of web site. By adapting these factors website developers can increase their site's page rank and within the PageRank concept, considering the rank of a document is given by the rank of those documents which link to it. Their rank again is given by the rank of documents which link to them. The PageRank of a document is always determined recursively by the PageRank of other documents.

Multiplex PageRank.

Directory of Open Access Journals (Sweden)

Full Text Available Many complex systems can be described as multiplex networks in which the same nodes can interact with one another in different layers, thus forming a set of interacting and co-evolving networks. Examples of such multiplex systems are social networks where people are involved in different types of relationships and interact through various forms of communication media. The ranking of nodes in multiplex networks is one of the most pressing and challenging tasks that research on complex networks is currently facing. When pairs of nodes can be connected through multiple links and in multiple layers, the ranking of nodes should necessarily reflect the importance of nodes in one layer as well as their importance in other interdependent layers. In this paper, we draw on the idea of biased random walks to define the Multiplex PageRank centrality measure in which the effects of the interplay between networks on the centrality of nodes are directly taken into account. In particular, depending on the intensity of the interaction between layers, we define the Additive, Multiplicative, Combined, and Neutral versions of Multiplex PageRank, and show how each version reflects the extent to which the importance of a node in one layer affects the importance the node can gain in another layer. We discuss these measures and apply them to an online multiplex social network. Findings indicate that taking the multiplex nature of the network into account helps uncover the emergence of rankings of nodes that differ from the rankings obtained from one single layer. Results provide support in favor of the salience of multiplex centrality measures, like Multiplex PageRank, for assessing the prominence of nodes embedded in multiple interacting networks, and for shedding a new light on structural properties that would otherwise remain undetected if each of the interacting networks were analyzed in isolation.

PAGE is a software package, written in BASIC language, to perform gamma spectra analysis. It was developed to be used in a high-purity intrinsic germanium detector-multichannel analyser-PC microcomputer system. The analysis program of PAGE package accomplishes functions as follows: peak location; gamma nuclides identification; activity determination. Standard nuclides sources were used to calibrate the system. To perform the efficiency x energy calibration a logarithmic fit was applied. Analysis of nuclides with overlapping peaks is allowed by PAGE program. PAGE has additional auxiliary programs for: building and list of isotopic nuclear data libraries; data acquisition from multichannel analyser; spectrum display with automatic area and FWHM determinations. This software is to be applied in analytical process control where time response is a very important parameter. PAGE takes ca. 1.5 minutes to analyse a complex spectrum from a 4096 channels MCA.

PageRank, HITS and a unified framework for link analysis

Energy Technology Data Exchange (ETDEWEB)

Ding, Chris; He, Xiaofeng; Husbands, Parry; Zha, Hongyuan; Simon, Horst

2001-10-01

Two popular webpage ranking algorithms are HITS and PageRank. HITS emphasizes mutual reinforcement between authority and hub webpages, while PageRank emphasizes hyperlink weight normalization and web surfing based on random walk models. We systematically generalize/combine these concepts into a unified framework. The ranking framework contains a large algorithm space; HITS and PageRank are two extreme ends in this space. We study several normalized ranking algorithms which are intermediate between HITS and PageRank, and obtain closed-form solutions. We show that, to first order approximation, all ranking algorithms in this framework, including PageRank and HITS, lead to same ranking which is highly correlated with ranking by indegree. These results support the notion that in web resource ranking indegree and outdegree are of fundamental importance. Rankings of webgraphs of different sizes and queries are presented to illustrate our analysis.

2016-02-01

Full Text Available Most of the ideas on service quality stem from the West. The massive developments in research in the West are undeniable of their importance. This leads to the generation and development of new ideas. These ideas were subsequently channeled to developing countries. Ideas obtained were then formulated and used by these developing countries in order to obtain better approach in channeling service quality. There are ample to be learnt from the service quality model, SERVQUAL which attain high acceptance in the West. Service quality in the education system is important to guarantee the effectiveness and quality of education. Effective and quality education will be able to offer quality graduates, which will contribute to the development of the nation. This paper will discuss the application of the SERVQUAL model into the education environment.

Chih, Wen-Hai; Hsu, Li-Chun; Wang, Kai-Yu; Lin, Kuan-Yu

2014-01-01

Using the dual mediation hypothesis, this study investigates the role of interestingness (the power of attracting or holding one's attention) attitude towards the news, in the formation of Facebook Fan Page users' electronic word-of-mouth intentions. A total of 599 Facebook fan page users in Taiwan were recruited and structural equation modeling (SEM) was used to test the research hypotheses. The results show that both perceived news entertainment and informativeness positively influence interestingness attitude towards the news. Interestingness attitude towards the news subsequently influences hedonism and utilitarianism attitudes towards the Fan Page, which then influence eWOM intentions. Interestingness attitude towards the news plays a more important role than hedonism and utilitarianism attitudes in generating electronic word-of-mouth intentions. Based on the findings, the implications and future research suggestions are provided.

Socorro Students Translate NRAO Web Pages Into Spanish

Science.gov (United States)

2002-07-01

Six Socorro High School students are spending their summer working at the National Radio Astronomy Observatory (NRAO) on a unique project that gives them experience in language translation, World Wide Web design, and technical communication. Under the project, called "Un puente a los cielos," the students are translating many of NRAO's Web pages on astronomy into Spanish. "These students are using their bilingual skills to help us make basic information about astronomy and radio telescopes available to the Spanish-speaking community," said Kristy Dyer, who works at NRAO as a National Science Foundation postdoctoral fellow and who developed the project and obtained funding for it from the National Aeronautics and Space Administration. The students are: Daniel Acosta, 16; Rossellys Amarante, 15; Sandra Cano, 16; Joel Gonzalez, 16; Angelica Hernandez, 16; and Cecilia Lopez, 16. The translation project, a joint effort of NRAO and the NM Tech physics department, also includes Zammaya Moreno, a teacher from Ecuador, Robyn Harrison, NRAO's education officer, and NRAO computer specialist Allan Poindexter. The students are translating NRAO Web pages aimed at the general public. These pages cover the basics of radio astronomy and frequently-asked questions about NRAO and the scientific research done with NRAO's telescopes. "Writing about science for non-technical audiences has to be done carefully. Scientific concepts must be presented in terms that are understandable to non-scientists but also that remain scientifically accurate," Dyer said. "When translating this type of writing from one language to another, we need to preserve both the understandability and the accuracy," she added. For that reason, Dyer recruited 14 Spanish-speaking astronomers from Argentina, Mexico and the U.S. to help verify the scientific accuracy of the Spanish translations. The astronomers will review the translations. The project is giving the students a broad range of experience. "They are

[The Application of Information and Communication Technology (ICT) in Nursing Education].

Chiou, Shwu-Fen; Su, Hsiu-Chuan; Huang, Ean-Wen

2017-12-01

With the rapid development of information and communication technologies (ICT) in the 21st century, all walks of life have experienced disruptive changes, including the healthcare profession. Although nurses represent the largest number of professionals in medical institutions, it is doubtful whether nurses possess sufficient capabilities to face challenges in this era of rapid medical informatization. Currently, the courses necessary to cultivate information literacy in nursing students are insufficient in Taiwan, and traditional instruction methods are largely adopted as nursing teaching strategies. Additionally, most teachers hold a passive attitude towards the application of ICT in teaching. On the contrary, ICT have been integrated into nursing education in many countries around the world for nearly 20 years, achieving good levels of teaching efficacy. Reflecting the Taiwan government's promotion of digital learning projects, academic circles in various fields have also started to gradually integrate ICT into teaching. Nursing educators in Taiwan have much to reference and to learn from these disparate integration experiences. Therefore, this article introduces the concepts of integration of ICT into teaching, the current status of the application of ICT in international nursing education, and the issues faced during this application as a reference for nursing education in Taiwan in order to promote the integration of ICT into nursing education.

Applications of the Cambridge Structural Database in chemical education1

Battle, Gary M.; Ferrence, Gregory M.; Allen, Frank H.

2010-01-01

The Cambridge Structural Database (CSD) is a vast and ever growing compendium of accurate three-dimensional structures that has massive chemical diversity across organic and metal–organic compounds. For these reasons, the CSD is finding significant uses in chemical education, and these applications are reviewed. As part of the teaching initiative of the Cambridge Crystallographic Data Centre (CCDC), a teaching subset of more than 500 CSD structures has been created that illustrate key chemical concepts, and a number of teaching modules have been devised that make use of this subset in a teaching environment. All of this material is freely available from the CCDC website, and the subset can be freely viewed and interrogated using WebCSD, an internet application for searching and displaying CSD information content. In some cases, however, the complete CSD System is required for specific educational applications, and some examples of these more extensive teaching modules are also discussed. The educational value of visualizing real three-dimensional structures, and of handling real experimental results, is stressed throughout. PMID:20877495

Modelling Safe Interface Interactions in Web Applications

Science.gov (United States)

Brambilla, Marco; Cabot, Jordi; Grossniklaus, Michael

Current Web applications embed sophisticated user interfaces and business logic. The original interaction paradigm of the Web based on static content pages that are browsed by hyperlinks is, therefore, not valid anymore. In this paper, we advocate a paradigm shift for browsers and Web applications, that improves the management of user interaction and browsing history. Pages are replaced by States as basic navigation nodes, and Back/Forward navigation along the browsing history is replaced by a full-fledged interactive application paradigm, supporting transactions at the interface level and featuring Undo/Redo capabilities. This new paradigm offers a safer and more precise interaction model, protecting the user from unexpected behaviours of the applications and the browser.

Smart photodetector arrays for error control in page-oriented optical memory

Science.gov (United States)

Schaffer, Maureen Elizabeth

1998-12-01

Page-oriented optical memories (POMs) have been proposed to meet high speed, high capacity storage requirements for input/output intensive computer applications. This technology offers the capability for storage and retrieval of optical data in two-dimensional pages resulting in high throughput data rates. Since currently measured raw bit error rates for these systems fall several orders of magnitude short of industry requirements for binary data storage, powerful error control codes must be adopted. These codes must be designed to take advantage of the two-dimensional memory output. In addition, POMs require an optoelectronic interface to transfer the optical data pages to one or more electronic host systems. Conventional charge coupled device (CCD) arrays can receive optical data in parallel, but the relatively slow serial electronic output of these devices creates a system bottleneck thereby eliminating the POM advantage of high transfer rates. Also, CCD arrays are "unintelligent" interfaces in that they offer little data processing capabilities. The optical data page can be received by two-dimensional arrays of "smart" photo-detector elements that replace conventional CCD arrays. These smart photodetector arrays (SPAs) can perform fast parallel data decoding and error control, thereby providing an efficient optoelectronic interface between the memory and the electronic computer. This approach optimizes the computer memory system by combining the massive parallelism and high speed of optics with the diverse functionality, low cost, and local interconnection efficiency of electronics. In this dissertation we examine the design of smart photodetector arrays for use as the optoelectronic interface for page-oriented optical memory. We review options and technologies for SPA fabrication, develop SPA requirements, and determine SPA scalability constraints with respect to pixel complexity, electrical power dissipation, and optical power limits. Next, we examine data

Gennaro Angiello

2016-03-01

Full Text Available Starting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always remaining in the groove of rigorous scientific in-depth analysis. During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it. The last section of the journal is formed by the Review Pages. They have different aims: to inform on the problems, trends and evolutionary processes; to investigate on the paths by highlighting the advanced relationships among apparently distant disciplinary fields; to explore the interaction’s areas, experiences and potential applications; to underline interactions, disciplinary developments but also, if present, defeats and setbacks. Inside the journal the Review Pages have the task of stimulating as much as possible the circulation of ideas and the discovery of new points of view. For this reason the section is founded on a series of basic’s references, required for the identification of new and more advanced interactions. These references are the research, the planning acts, the actions and the applications, analysed and investigated both for their ability to give a systematic response to questions concerning the urban and territorial planning, and for their attention to aspects such as the environmental sustainability and the innovation in the practices. For this purpose the Review Pages are formed by five sections (Web Resources; Books; Laws; Urban Practices; News and Events, each of which examines a specific aspect of the broader information storage of interest for TeMA

EFNEP graduates' perspectives on social media to supplement nutrition education: focus group findings from active users.

2014-01-01

To identify ways to effectively use social media to communicate nutrition-related information to low-income populations. The authors conducted 4 focus groups with female Expanded Food and Nutrition Education Program graduates who used social media at least twice a week (n = 26 total). Transcripts were analyzed using the constant comparative method to identify key themes. For participants, page content, page maintenance, and networking opportunities with others were important aspects of a nutrition education social media page. Trust emerged as a central theme, because participants expressed a need for reliable information from known, credible sources and safe places to share ideas. Using social media to provide nutrition-related messages may be an effective way to encourage sustained positive behavior changes resulting from educational programming and to engage participants beyond class time. Establishing the trustworthiness of the social media site is essential to its use among low-income participants. Copyright © 2014 Society for Nutrition Education and Behavior.

McDonough, Brianna; Felter, Elizabeth; Downes, Amia; Trauth, Jeanette

2015-04-01

Pregnant and postpartum women have special needs during public health emergencies but often have inadequate levels of disaster preparedness. Thus, improving maternal emergency preparedness is a public health priority. More research is needed to identify the strengths and weaknesses of various approaches to how preparedness information is communicated to these women. A sample of web pages from the Centers for Disease Control and Prevention intended to address the preparedness needs of pregnant and postpartum populations was examined for suitability for this audience. Five of the 7 web pages examined were considered adequate. One web page was considered not suitable and one the raters split between not suitable and adequate. None of the resources examined were considered superior. If these resources are considered some of the best available to pregnant and postpartum women, more work is needed to improve the suitability of educational resources, especially for audiences with low literacy and low incomes.

Poisson statistics of PageRank probabilities of Twitter and Wikipedia networks

Science.gov (United States)

Frahm, Klaus M.; Shepelyansky, Dima L.

2014-04-01

We use the methods of quantum chaos and Random Matrix Theory for analysis of statistical fluctuations of PageRank probabilities in directed networks. In this approach the effective energy levels are given by a logarithm of PageRank probability at a given node. After the standard energy level unfolding procedure we establish that the nearest spacing distribution of PageRank probabilities is described by the Poisson law typical for integrable quantum systems. Our studies are done for the Twitter network and three networks of Wikipedia editions in English, French and German. We argue that due to absence of level repulsion the PageRank order of nearby nodes can be easily interchanged. The obtained Poisson law implies that the nearby PageRank probabilities fluctuate as random independent variables.

How the Facebook Arabic Page “We Are All Khaled Said” Helped Promote the Egyptian Revolution

Directory of Open Access Journals (Sweden)

Kara Alaimo

2015-09-01

Full Text Available This study analyzes how the owner of the Facebook Arabic page “We Are All Khaled Said” both catalyzed and took advantage of opportunities in the Egyptian political climate in order to help promote the country’s 2011 revolution. Using a content analysis of posts on the Facebook page before and throughout the Egyptian revolution, the case study finds that the owner of the page, Wael Ghonim, served as a long-term trainer or coach, educating his online followers about the abuses of Egyptian President Hosni Mubarak’s regime and helping them gradually become more comfortable with political activism, so that when a triggering event—the Tunisian revolution—occurred, he was able to move his followers into the streets to protest. Two other particularly successful tactics were utilized by Ghonim: He capitalized on a powerful personal story—that of a young man brutally killed by the police—in order to elicit emotion and help others identify with the cause, and he used lofty rhetoric to convince his followers that their actions could actually make a difference. The case study disproves Gladwell’s (2010 claim that social media is a platform for shallow and networked interactions, finding both that the grievances and ideas shared on this page were remarkably substantive and that the movement was not a network but rather a hierarchy, led by Ghonim until his imprisonment. The study suggests that social media is a more powerful platform for promoting political change than previously appreciated and offers important lessons for political activists.

Automatic comic page image understanding based on edge segment analysis

Science.gov (United States)

Liu, Dong; Wang, Yongtao; Tang, Zhi; Li, Luyuan; Gao, Liangcai

2013-12-01

Comic page image understanding aims to analyse the layout of the comic page images by detecting the storyboards and identifying the reading order automatically. It is the key technique to produce the digital comic documents suitable for reading on mobile devices. In this paper, we propose a novel comic page image understanding method based on edge segment analysis. First, we propose an efficient edge point chaining method to extract Canny edge segments (i.e., contiguous chains of Canny edge points) from the input comic page image; second, we propose a top-down scheme to detect line segments within each obtained edge segment; third, we develop a novel method to detect the storyboards by selecting the border lines and further identify the reading order of these storyboards. The proposed method is performed on a data set consisting of 2000 comic page images from ten printed comic series. The experimental results demonstrate that the proposed method achieves satisfactory results on different comics and outperforms the existing methods.

Engström, Christopher; Silvestrov, Sergei

2017-01-01

PageRank was initially developed by S. Brinn and L. Page in 1998 to rank homepages on the Internet using the stationary distribution of a Markov chain created using the web graph. Due to the large size of the web graph and many other real world networks fast methods to calculate PageRank is needed and even if the original way of calculating PageRank using a Power iterations is rather fast, many other approaches have been made to improve the speed further. In this paper we will consider the problem of recalculating PageRank of a changing network where the PageRank of a previous version of the network is known. In particular we will consider the special case of adding or removing edges to a single vertex in the graph or graph component.

Block models and personalized PageRank.

Science.gov (United States)

Kloumann, Isabel M; Ugander, Johan; Kleinberg, Jon

2017-01-03

Methods for ranking the importance of nodes in a network have a rich history in machine learning and across domains that analyze structured data. Recent work has evaluated these methods through the "seed set expansion problem": given a subset [Formula: see text] of nodes from a community of interest in an underlying graph, can we reliably identify the rest of the community? We start from the observation that the most widely used techniques for this problem, personalized PageRank and heat kernel methods, operate in the space of "landing probabilities" of a random walk rooted at the seed set, ranking nodes according to weighted sums of landing probabilities of different length walks. Both schemes, however, lack an a priori relationship to the seed set objective. In this work, we develop a principled framework for evaluating ranking methods by studying seed set expansion applied to the stochastic block model. We derive the optimal gradient for separating the landing probabilities of two classes in a stochastic block model and find, surprisingly, that under reasonable assumptions the gradient is asymptotically equivalent to personalized PageRank for a specific choice of the PageRank parameter [Formula: see text] that depends on the block model parameters. This connection provides a formal motivation for the success of personalized PageRank in seed set expansion and node ranking generally. We use this connection to propose more advanced techniques incorporating higher moments of landing probabilities; our advanced methods exhibit greatly improved performance, despite being simple linear classification rules, and are even competitive with belief propagation.

Educational Applications on the World Wide Web: An Example Using Amphion

Science.gov (United States)

Friedman, Jane

1998-01-01

There is a great deal of excitement about using the internet and the World Wide Web in education. There are such exciting possibilities and there is a wealth and variety of material up on the web. There are however many problems, problems of access and resources, problems of quality -- for every excellent resource there are many poor ones, and there are insufficiently explored problems of teacher training and motivation. For example, Wiesenmayer and Meadows report on a study of 347 West Virginia science teachers. These teachers were enrolled in a week-long summer workshop to introduce them to the internet and its educational potential. The teachers were asked to review science sites as to overall quality and then about their usefulness in their own classrooms. The teachers were enthusiastic about the web, and gave two-thirds of the sites high ratings, and essentially all the rest average ratings. But alarmingly, over 80% of these sites were viewed as having no direct applicability in the teacher's own classroom. This summer I was assigned to work on the Amphion project in the Automated Software Engineering Group under the leadership of Michael Lowry. I wished to find educational applications of the Amphion system, which in its current implementation can be used to create fortran programs and animations using the SPICE libraries created by the NAIF group at JPL. I wished to find an application which provided real added educational value, which was in line with educational curriculum standards and which would serve a documented need of the educational community. The application selected was teaching about the causes of the seasons -- at the approximately the fourth, fifth, sixth grade level. This topic was chosen because it is in line with national curriculum standards. The fourth, fifth, sixth grade level was selected to coincide with the grade level served by the Ames Aerospace Encounter, which services 10,000 children a year on field trips. The hope is that

Improving Interdisciplinary Provider Communication Through a Unified Paging System.

Heidemann, Lauren; Petrilli, Christopher; Gupta, Ashwin; Campbell, Ian; Thompson, Maureen; Cinti, Sandro; Stewart, David A

2016-06-01

Interdisciplinary communication at a Veterans Affairs (VA) academic teaching hospital is largely dependent on alphanumeric paging, which has limitations as a result of one-way communication and lack of reliable physician identification. Adverse patient outcomes related to difficulty contacting the correct consulting provider in a timely manner have been reported. House officers were surveyed on the level of satisfaction with the current VA communication system and the rate of perceived adverse patient outcomes caused by potential delays within this system. Respondents were then asked to identify the ideal paging system. These results were used to develop and deploy a new Web site. A postimplementation survey was repeated 1 year later. This study was conducted as a quality improvement project. House officer satisfaction with the preintervention system was 3%. The majority used more than four modalities to identify consultants, with 59% stating that word of mouth was a typical source. The preferred mode of paging was the university hospital paging system, a Web-based program that is used at the partnering academic institution. Following integration of VA consulting services within the university hospital paging system, the level of satisfaction improved to 87%. Significant decreases were seen in perceived adverse patient outcomes (from 16% to 2%), delays in patient care (from 90% to 16%), and extended hospitalizations (from 46% to 4%). Our study demonstrates significant improvement in physician satisfaction with a newly implemented paging system that was associated with a decreased perceived number of adverse patient events and delays in care.

This study investigates the effects of picture amount on subjective evaluation. The experiment herein adopted two variables to define picture amount: column ratio and picture size. Six column ratios were employed: 7:93,15:85, 24:76, 33:67, 41:59, and 50:50. Five picture sizes were examined: 140 x 81, 220 x 127, 300 x 173, 380 x 219, and 460 x 266 pixels. The experiment implemented a within-subject design; 104 participants were asked to evaluate 30 web page layouts. Repeated measurements revealed that the column ratio and picture size have significant effects on preference, balance, and dynamic feel. The results indicated the most appropriate picture amount for display: column ratios of 15:85 and 24:76, and picture sizes of 220 x 127, 300 x 173, and 380 x 219. The research findings can serve as the basis for the application of design guidelines for future web page interface design.

Fish is an important causative material of food allergy. Although the allergenicity of fish is considered to correlate with the content of parvalbumin, the major fish allergen, available information about the parvalbumin content in fish is limited. In this study, a simple and reliable quantification method for fish parvalbumin by SDS-PAGE was first established. Application of the SDS-PAGE method to 22 species of fish revealed a marked variation in parvalbumin content among fish. Furthermore, the parvalbumin content was found to be higher in dorsal white muscle than in ventral white muscle, in rostral part of white muscle than in caudal part of white muscle and in white muscle than in dark muscle. IgE reactivity of fish was roughly proportional to parvalbumin content. Interestingly, large-sized migratory fish, such as salmon, swordfish and tuna, were commonly very low in both parvalbumin content and IgE reactivity. Copyright © 2015 Elsevier Ltd.

SurveyWiz and factorWiz: JavaScript Web pages that make HTML forms for research on the Internet.

Science.gov (United States)

Birnbaum, M H

2000-05-01

SurveyWiz and factorWiz are Web pages that act as wizards to create HTML forms that enable one to collect data via the Web. SurveyWiz allows the user to enter survey questions or personality test items with a mixture of text boxes and scales of radio buttons. One can add demographic questions of age, sex, education, and nationality with the push of a button. FactorWiz creates the HTML for within-subjects, two-factor designs as large as 9 x 9, or higher order factorial designs up to 81 cells. The user enters levels of the row and column factors, which can be text, images, or other multimedia. FactorWiz generates the stimulus combinations, randomizes their order, and creates the page. In both programs HTML is displayed in a window, and the user copies it to a text editor to save it. When uploaded to a Web server and supported by a CGI script, the created Web pages allow data to be collected, coded, and saved on the server. These programs are intended to assist researchers and students in quickly creating studies that can be administered via the Web.

2015-01-01

Learning theories are the main guide for educational systems planning in the classroom and clinical training included in nursing. The teachers by knowing the general principles of these theories can use their knowledge more effectively according to various learning situations. In this study, Eric, Medline, and Cochrane databases were used for articles in English and for the Persian literature, Magiran, Iran doc, Iran medex, and Sid databases were used with the help of keywords including social cognitive learning, learning theory, behavioral theory, cognitive theory, constructive theory, and nursing education. The search period was considered from 1990 to 2012. Some related books were also studied about each method, its original vision, the founders, practical application of the training theory, especially training of nursing and its strengths and weaknesses. Behaviorists believe that learning is a change in an observable behavior and it happens when the communication occurs between the two events, a stimulus and a response. Among the applications of this approach is the influence on the learner's emotional reactions. Among the theories of this approach, Thorndike and Skinner works are subject to review and critique. Cognitive psychologists unlike the behaviorists believe that learning is an internal process objective and they focus on thinking, understanding, organizing, and consciousness. Fundamentalists believe that learners should be equipped with the skills of inquiry and problem solving in order to learn by the discovery and process of information. Among this group, we will pay attention to analyze Wertheimer, Brunner, Ausubel theories, Ganyeh information processing model, in addition to its applications in nursing education. Humanists in learning pay attention to the feelings and experiences. Carl Rogers support the retention of learning-centered approach and he is believed to a semantic continuum.

Quality of drug information on the World Wide Web and strategies to improve pages with poor information quality. An intervention study on pages about sildenafil.

Science.gov (United States)

Martin-Facklam, Meret; Kostrzewa, Michael; Martin, Peter; Haefeli, Walter E

2004-01-01

The generally poor quality of health information on the world wide web (WWW) has caused preventable adverse outcomes. Quality management of information on the internet is therefore critical given its widespread use. In order to develop strategies for the safe use of drugs, we scored general and content quality of pages about sildenafil and performed an intervention to improve their quality. The internet was searched with Yahoo and AltaVista for pages about sildenafil and 303 pages were included. For assessment of content quality a score based on accuracy and completeness of essential drug information was assigned. For assessment of general quality, four criteria were evaluated and their association with high content quality was determined by multivariate logistic regression analysis. The pages were randomly allocated to either control or intervention group. Evaluation took place before, as well as 7 and 22 weeks after an intervention which consisted of two letters with individualized feedback information on the respective page which were sent electronically to the address mentioned on the page. Providing references to scientific publications or prescribing information was significantly associated with high content quality (odds ratio: 8.2, 95% CI 3.2, 20.5). The intervention had no influence on general or content quality. To prevent adverse outcomes caused by misinformation on the WWW individualized feedback to the address mentioned on the page was ineffective. It is currently probably the most straight-forward approach to inform lay persons about indicators of high information quality, i.e. the provision of references.

Gender Prototype Representation in Media: Case Study of Hamshahri’s Events Page

Directory of Open Access Journals (Sweden)

Heshmat Sadat Moini Far

2009-11-01

Full Text Available Besides family and education system, media also affects on the socializing process. What media represent is mutually affected and affective with culture. However, there are some times when media’s effect on society is especially important. For example, people with restricted social interactions would spend more time watching TV; thus what they watch not only entertains, but also has educational effects on them, this is the same for journals with habitual readers. Reviewing Hamshahri’s events page, this study attempts to study social construction of gender prototypes. Applying gender role theory and theory of gender sociability, this study would offer a hybrid model. As results show, men are more inclined to commit a crime, and women are usually the object of crimes. The most sensible prototype is that men are represented as “aggressive and raper”, while women are the victims. Described prototypes are both descriptive and normative.

Network and User-Perceived Performance of Web Page Retrievals

Science.gov (United States)

Kruse, Hans; Allman, Mark; Mallasch, Paul

1998-01-01

The development of the HTTP protocol has been driven by the need to improve the network performance of the protocol by allowing the efficient retrieval of multiple parts of a web page without the need for multiple simultaneous TCP connections between a client and a server. We suggest that the retrieval of multiple page elements sequentially over a single TCP connection may result in a degradation of the perceived performance experienced by the user. We attempt to quantify this perceived degradation through the use of a model which combines a web retrieval simulation and an analytical model of TCP operation. Starting with the current HTTP/l.1 specification, we first suggest a client@side heuristic to improve the perceived transfer performance. We show that the perceived speed of the page retrieval can be increased without sacrificing data transfer efficiency. We then propose a new client/server extension to the HTTP/l.1 protocol to allow for the interleaving of page element retrievals. We finally address the issue of the display of advertisements on web pages, and in particular suggest a number of mechanisms which can make efficient use of IP multicast to send advertisements to a number of clients within the same network.

The objective of the present study was to evaluate the quality of general health information in Spanish language web pages, and the official Regional Services web pages from the different Autonomous Regions. It is a cross-sectional study. We have used a previously validated questionnaire to study the present state of the health information on Internet for a lay-user point of view. By mean of PageRank (Google®), we obtained a group of webs, including a total of 65 health web pages. We applied some exclusion criteria, and finally obtained a total of 36 webs. We also analyzed the official web pages from the different Health Services in Spain (19 webs), making a total of 54 health web pages. In the light of our data, we observed that, the quality of the general information health web pages was generally rather low, especially regarding the information quality. Not one page reached the maximum score (19 points). The mean score of the web pages was of 9.8±2.8. In conclusion, to avoid the problems arising from the lack of quality, health professionals should design advertising campaigns and other media to teach the lay-user how to evaluate the information quality.

Kootsey, J Mailen; Siriphongs, Daniel; McAuley, Grant

2004-01-01

A new Web software architecture, NumberLinX (NLX), has been integrated into a commercial Web design program to produce a drag-and-drop environment for building interactive simulations. NLX is a library of reusable objects written in Java, including input, output, calculation, and control objects. The NLX objects were added to the palette of available objects in the Web design program to be selected and dropped on a page. Inserting an object in a Web page is accomplished by adding a template block of HTML code to the page file. HTML parameters in the block must be set to user-supplied values, so the HTML code is generated dynamically, based on user entries in a popup form. Implementing the object inspector for each object permits the user to edit object attributes in a form window. Except for model definition, the combination of the NLX architecture and the Web design program permits construction of interactive simulation pages without writing or inspecting code.

Ranking nodes in growing networks: When PageRank fails.

PageRank is arguably the most popular ranking algorithm which is being applied in real systems ranging from information to biological and infrastructure networks. Despite its outstanding popularity and broad use in different areas of science, the relation between the algorithm's efficacy and properties of the network on which it acts has not yet been fully understood. We study here PageRank's performance on a network model supported by real data, and show that realistic temporal effects make PageRank fail in individuating the most valuable nodes for a broad range of model parameters. Results on real data are in qualitative agreement with our model-based findings. This failure of PageRank reveals that the static approach to information filtering is inappropriate for a broad class of growing systems, and suggest that time-dependent algorithms that are based on the temporal linking patterns of these systems are needed to better rank the nodes.

Educational and Scientific Applications of the \\itTime Navigator}

Science.gov (United States)

Cole, M.; Snow, J. T.; Slatt, R. M.

2001-05-01

Several recent conferences have noted the need to focus on the evolving interface between research and education at all levels of science, mathematics, engineering, and technology education. This interface, which is a distinguishing feature of graduate education in the U.S., is increasingly in demand at the undergraduate and K-12 levels, particularly in the earth sciences. In this talk, we present a new database for earth systems science and will explore applications to K-12 and undergraduate education, as well as the scientific and graduate role. The University of Oklahoma, College of Geosciences is in the process of acquiring the \\itTime Navigator}, a multi-disciplinary, multimedia database, which will form the core asset of the Center for Earth Systems Science. The Center, whose mission is to further the understanding of the dynamic Earth within both the academic and the general public communities, will serve as a portal for research, information, and education for scientists and educators. \\itTime Navigator} was developed over a period of some twenty years by the noted British geoscience author, Ron Redfern, in connection with the recently published, \\itOrigins, the evolution of continents, oceans and life}, the third in a series of books for the educated layperson. Over the years \\itTime Navigator} has evolved into an interactive, multimedia database displaying much of the significant geological, paleontological, climatological, and tectonic events from the latest Proterozoic (750 MYA) through to the present. The focus is mainly on the Western Hemisphere and events associated with the coalescence and breakup of Pangea and the evolution of the earth into its present form. \\itOrigins} will be available as early as Fall 2001 as an interactive electronic book for the general, scientifically-literate public. While electronic books are unlikely to replace traditional print books, the format does allow non-linear exploration of content. We believe that the

The application of wiki technology in medical education.

Science.gov (United States)

Rasmussen, Andrew; Lewis, Melanie; White, Jonathan

2013-01-01

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

Continuing medical education effect on physician knowledge application and psychomotor skills: effectiveness of continuing medical education: American College of Chest Physicians Evidence-Based Educational Guidelines.

Science.gov (United States)

O'Neil, Kevin M; Addrizzo-Harris, Doreen J

2009-03-01

Recommendations for optimizing continuing medical education (CME) effectiveness in improving physician application of knowledge and psychomotor skills are needed to guide the development of processes that effect physician change and improve patient care. The guideline panel reviewed evidence tables and a comprehensive review of the effectiveness of CME developed by The Johns Hopkins Evidence-based Practice Center for the Agency for Healthcare Research and Quality (AHRQ Evidence Report). The panel considered studies relevant to the effect of CME on physician knowledge application and psychomotor skill development. From the 136 studies identified in the systematic review, 15 articles, 12 addressing physician application of knowledge and 3 addressing psychomotor skills, were identified and reviewed. Recommendations for optimizing CME were developed using the American College of Chest Physicians guideline grading system. The preponderance of evidence demonstrated improvement in physician application of knowledge with CME. The quality of evidence did not allow specific recommendations regarding optimal media or educational techniques or the effectiveness of CME in improving psychomotor skills. CME is effective in improving physician application of knowledge. Multiple exposures and longer durations of CME are recommended to optimize educational outcomes.

Full Text Available Page tagging is one of the most important facilities for increasing the accuracy of information retrieval in the web. Tags are simple pieces of data that usually consist of one or several words, and briefly describe a page. Tags provide useful information about a page and can be used for boosting the accuracy of searching, document clustering, and result grouping. The most accurate solution to page tagging is using human experts. However, when the number of pages is large, humans cannot be used, and some automatic solutions should be used instead. We propose a solution called PerTag which can automatically tag a set of Persian web pages. PerTag is based on n-gram models and uses the tf-idf method plus some effective Persian language rules to select proper tags for each web page. Since our target is huge sets of web pages, PerTag is built on top of the MapReduce distributed computing framework. We used a set of more than 500 million Persian web pages during our experiments, and extracted tags for each page using a cluster of 40 machines. The experimental results show that PerTag is both fast and accurate

Full Text Available Employment of applicants of pharmaceutical higher education has both positive and negative impact on the quality of educational services provided by institutions, especially in terms of knowledge and skills acquired by student. Objective is to study peculiarities of higher education employment, full-time training, and features driving them to conclude labor agreements. Materials and methods. During the study, we used juridical and comparative legal methods of analysis. Results. The study has defined the following features of the employment of applicants of higher education in the health care institutions, pharmaceutical enterprises and organizations. The current legislation provides the applicants of higher education enrolled in HEIs for full-time training with a right to make a free choice of the field of study, profession, type of occupation and work. The relationship developed between an applicant and higher education institutions are not to be regarded as an employment relationship. The working under the items of labor agreement for person who combine it with the full-time education is not a part or combination or sharing, and is considered the main place of job. Thus, it stipulates maintenance of records book of the employed worker according to the general procedure. An applicant of higher education has discretion to choose working hours (full- or part-time working day, full- or part-time working week with taking into consideration the HEIs schedule and only in the free time. When full-time operating in frameworks of collective agreement at enterprise, institution, or organization, having accounted peculiarities of operation, non-standardized working day for some positions can be set. The current legislation stipulates possibility of employment for persons without higher pharmaceutical education to the health care institutions on the clearly defined positions. Conclusions.The country authority has created and is providing favorable

2017-01-01

Full Text Available This research aims to find negative and positive aspects within the transported education system thanks to the teachers’ evaluation for the application of transported education. The research is a qualitative research. Interview form was used in order to collect the data. Teachers were asked 6 questions in the form. The research was carried out in Kaynarca in Sakarya. It was implemented on 20 teachers at 2 schools. It is concluded that transported education enables considerably equal opportunities. There are much more opportunities in the school to which transportion is realized and this application enhances the students’ success in the school. However, drivers should be given seminars and courses because their communication skills are quite inefficient. It is also concluded that transported children get tired because of the fact that they spend too much time in the school bus and this affects negatively the children’s performances at school. Moreover , family-teacher communication weakens through time.

BACKGROUND: Practice audit is an important component of continuing professional development that may more readily be undertaken if it were less complex. This qualitative study assessed the use of personal digital assistants to facilitate data collection and review. METHODS: Personal digital assistants programmed with standard questionnaires related to upper gastrointestinal endoscopies (Practice Audit in Gastroenterology-Endoscopy [‘PAGE-Endo’]) and colonoscopies (PAGE-Colonoscopy [‘PAGE-Colo’]) were provided to Canadian gastroenterologists, surgeons and internists. Over a three-week audit period, participants recorded indications, and the expected (E) and reported (R) findings for each procedure. Thereafter, participants recorded compliance with reporting, the ease of use and value of the PAGE program, and their willingness to perform another audit. RESULTS: Over 15 to 18 months, 173 participants completed PAGE-Endo (6168 procedures) and 111 completed PAGE-Colo (4776 procedures). Most respondents noted that PAGE was easy to use (99%), beneficial (88% to 95%), and that they were willing undertake another audit (92% to 95%). In PAGE-Endo, alarm features were prevalent (55%), but major reported findings were less common than expected: esophagitis (E 29.9%, R 14.8%), esophageal stricture (E 8.3%, R 3.6%), gastric ulcer (E 17.0%, R 4.7%), gastric cancer (E 4.3%, R 1.0%) and duodenal ulcer (E 11.5%, R 5.7%). In PAGE-Colo, more colonoscopies were performed for symptom investigation (55%) than for screening (25%) or surveillance (20%). There were marked interprovincial variations with respect to sedation, biopsies and technical aspects of colonoscopy. CONCLUSION: Secure, real-time data entry with review of aggregate and individual data in the PAGE program provided an acceptable, straightforward methodology for accredited practice audit activities. PAGE has considerable potential for continuing professional development in gastroenterology and other specialties

The purpose of this study is to assess the utility of CT paging arteriography with a multidetector-row CT as a replacement for conventional angiography in the evaluation of splanchnic arterial anomalies. Sixty-three patients underwent CT paging arteriography with a multidetector-row CT. In the 56 patients with conventional angiographic correlation, there was only one minor disagreement with CT paging arteriography. In the 7 patients who underwent IVDSA (intra venous digital subtraction angiography), CT paging arteriography defined four hepatic arterial anomalies which could not be depicted by IVDSA. In conclusion, CT paging arteriography provides noninvasive means to identify splanchnic arterial anomalies. (author)

Handzel, D M

2012-06-01

The use of the internet is becoming more and more important in every aspect of daily life, also in professional education. Online education and face-to-face learning have proven to be equally efficient. The aim of this study is to evaluate the amount of online education in the German-speaking internet 2011. The terms "ophthalmology", "online-education", "continuing medical education" and "CME" (partly in German language) were searched by an internet-search engine. The first 100 pages were visited. Pages were evaluated in respect of quality and quantity, authorship and possible influence of sponsors. Only 9 of the first 100 hits had an actual offer for ophthalmology. Nearly all of these were websites of ophthalmological scientific journals. The content represented the same educational format (pictures and text) as in the print issue. CME-certified online education can be found in Germany as offspring of print issues only. The content is identical with educational texts in the print issues. An enlargement of the offer, which uses the possibilities of modern internet technology is highly probable. This estimation is supported by the growing use of the internet and developments on English-speaking websites for online-education. © Georg Thieme Verlag KG Stuttgart · New York.

Lai, William Y. Y.; Lane, Trevor; Jones, Alison

2009-01-01

Background Medical news that appears on newspaper front pages is intended to reach a wide audience, but how this type of medical news is prepared and distributed has not been systematically researched. We thus quantified the level of visibility achieved by front-page medical stories in the United States and analyzed their news sources. Methodology Using the online resource Newseum, we investigated front-page newspaper coverage of four prominent medical stories, and a high-profile non-medical news story as a control, reported in the US in 2007. Two characteristics were quantified by two raters: which newspaper titles carried each target front-page story (interrater agreement, >96%; kappa, >0.92) and the news sources of each target story (interrater agreement, >94%; kappa, >0.91). National rankings of the top 200 US newspapers by audited circulation were used to quantify the extent of coverage as the proportion of the total circulation of ranked newspapers in Newseum. Findings In total, 1630 front pages were searched. Each medical story appeared on the front pages of 85 to 117 (67.5%–78.7%) ranked newspaper titles that had a cumulative daily circulation of 23.1 to 33.4 million, or 61.8% to 88.4% of all newspapers. In contrast, the non-medical story achieved front-page coverage in 152 (99.3%) newspaper titles with a total circulation of 41.0 million, or 99.8% of all newspapers. Front-page medical stories varied in their sources, but the Washington Post, Los Angeles Times, New York Times and the Associated Press together supplied 61.7% of the total coverage of target front-page medical stories. Conclusion Front-page coverage of medical news from different sources is more accurately revealed by analysis of circulation counts rather than of newspaper titles. Journals wishing to widen knowledge of research news and organizations with important health announcements should target at least the four dominant media organizations identified in this study.

Measuring consistency of web page design and its effects on performance and satisfaction.

Science.gov (United States)

Ozok, A A; Salvendy, G

2000-04-01

This study examines the methods for measuring the consistency levels of web pages and the effect of consistency on the performance and satisfaction of the world-wide web (WWW) user. For clarification, a home page is referred to as a single page that is the default page of a web site on the WWW. A web page refers to a single screen that indicates a specific address on the WWW. This study has tested a series of web pages that were mostly hyperlinked. Therefore, the term 'web page' has been adopted for the nomenclature while referring to the objects of which the features were tested. It was hypothesized that participants would perform better and be more satisfied using web pages that have consistent rather than inconsistent interface design; that the overall consistency level of an interface design would significantly correlate with the three elements of consistency, physical, communicational and conceptual consistency; and that physical and communicational consistencies would interact with each other. The hypotheses were tested in a four-group, between-subject design, with 10 participants in each group. The results partially support the hypothesis regarding error rate, but not regarding satisfaction and performance time. The results also support the hypothesis that each of the three elements of consistency significantly contribute to the overall consistency of a web page, and that physical and communicational consistencies interact with each other, while conceptual consistency does not interact with them.

Bucksch, Jens; Kolip, Petra; Deitermann, Bernhilde

2004-01-01

The present study was designed to analyse Web pages of German gynaecologists with regard to postmenopausal hormone therapy (HT). There is a growing body of evidence, that the overall health risks of HT exceed the benefits. Making one's own informed choice has become a central concern for menopausal women. The Internet is an important source of health information, but the quality is often dubious. The study focused on the analysis of basic criteria such as last modification date and quality of the HT information content. The results of the Women's Health Initiative Study (WHI) were used as a benchmark. We searched for relevant Web pages by entering a combination of key words (9 x 13 = 117) into the search engine www.google.de. Each Web page was analysed using a standardized questionnaire. The basic criteria and the quality of content on each Web page were separately categorized by two evaluators. Disagreements were resolved by discussion. Of the 97 websites identified, basic criteria were not met by the majority. For example, the modification date was displayed by only 23 (23.7%) Web pages. The quality of content of most Web pages regarding HT was inaccurate and incomplete. Whilst only nine (9.3%) took up a balanced position, 66 (68%) recommended HT without any restrictions. In 22 cases the recommendation was indistinct and none of the sites refused HT. With regard to basic criteria, there was no difference between HT-recommending Web pages and sites with balanced position. Evidence-based information resulting from the WHI trial was insufficiently represented on gynaecologists' Web pages. Because of the growing number of consumers looking online for health information, the danger of obtaining harmful information has to be minimized. Web pages of gynaecologists do not appear to be recommendable for women because they do not provide recent evidence-based findings about HT.

This paper discusses the application of electronic media to documents, specifically Safety Analysis Reports (SARs), prepared for Environmental Restoration and Waste Management (ER ampersand WM) programs being conducted for the Department of Energy (DOE) at the Idaho National Engineering Laboratory (INEL). Efforts are underway to upgrade our document system using electronic format. To satisfy external requirements (DOE, State, and Federal), ER ampersand WM programs generate a complement of internal requirements documents including a SAR and Technical Safety Requirements along with procedures and training materials. Of interest, is the volume of information and the difficulty in handling it. A recently prepared ER ampersand WM SAR consists of 1,000 pages of text and graphics; supporting references add 10,000 pages. Other programmatic requirements documents consist of an estimated 5,000 pages plus references

Creating a Facebook Page for the Seismological Society of America

Science.gov (United States)

Newman, S. B.

2009-12-01

In August, 2009 I created a Facebook “fan” page for the Seismological Society of America. We had been exploring cost-effective options for providing forums for two-way communication for some months. We knew that a number of larger technical societies had invested significant sums of money to create customized social networking sites but that a small society would need to use existing low-cost software options. The first thing I discovered when I began to set up the fan page was that an unofficial SSA Facebook group already existed, established by Steven J. Gibbons, a member in Norway. Steven had done an excellent job of posting material about SSA. Partly because of the existing group, the official SSA fan page gained fans rapidly. We began by posting information about our own activities and then added links to activities in the broader geoscience community. While much of this material also appeared on our website and in our publication, Seismological Research Letters (SRL), the tone on the FB page is different. It is less formal with more emphasis on photos and links to other sites, including our own. Fans who are active on FB see the posts as part of their social network and do not need to take the initiative to go to the SSA site. Although the goal was to provide a forum for two-way communication, our initial experience was that people were clearly reading the page but not contributing content. This appears to be case with fan pages of sister geoscience societies. FB offers some demographic information to fan site administrators. In an initial review of the demographics it appeared that fans were younger than the overall demographics of the Society. It appeared that a few of the fans are not members or even scientists. Open questions are: what content will be most useful to fans? How will the existence of the page benefit the membership as a whole? Will the page ultimately encourage two-way communication as hoped? Web 2.0 is generating a series of new

Near-Duplicate Web Page Detection: An Efficient Approach Using Clustering, Sentence Feature and Fingerprinting

2013-02-01

Full Text Available Duplicate and near-duplicate web pages are the chief concerns for web search engines. In reality, they incur enormous space to store the indexes, ultimately slowing down and increasing the cost of serving results. A variety of techniques have been developed to identify pairs of web pages that are aldquo;similarardquo; to each other. The problem of finding near-duplicate web pages has been a subject of research in the database and web-search communities for some years. In order to identify the near duplicate web pages, we make use of sentence level features along with fingerprinting method. When a large number of web documents are in consideration for the detection of web pages, then at first, we use K-mode clustering and subsequently sentence feature and fingerprint comparison is used. Using these steps, we exactly identify the near duplicate web pages in an efficient manner. The experimentation is carried out on the web page collections and the results ensured the efficiency of the proposed approach in detecting the near duplicate web pages.

Review Pages: Planning for Livable and Safe Cities: Energy, Pollution and the Degradation of the Urban Environment

2016-08-01

Full Text Available Starting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always remaining in the groove of rigorous scientific in-depth analysis. During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it. The last section of the journal is formed by the Review Pages. They have different aims: to inform on the problems, trends and evolutionary processes; to investigate on the paths by highlighting the advanced relationships among apparently distant disciplinary fields; to explore the interaction’s areas, experiences and potential applications; to underline interactions, disciplinary developments but also, if present, defeats and setbacks. Inside the journal the Review Pages have the task of stimulating as much as possible the circulation of ideas and the discovery of new points of view. For this reason the section is founded on a series of basic’s references, required for the identification of new and more advanced interactions. These references are the research, the planning acts, the actions and the applications, analysed and investigated both for their ability to give a systematic response to questions concerning the urban and territorial planning, and for their attention to aspects such as the environmental sustainability and the innovation in the practices. For this purpose the Review Pages are formed by five sections (Web Resources; Books; Laws; Urban Practices; News and Events, each of which examines a specific aspect of the broader information storage of interest for TeMA

An Optimization Model for Product Placement on Product Listing Pages

Directory of Open Access Journals (Sweden)

Yan-Kwang Chen

2014-01-01

Full Text Available The design of product listing pages is a key component of Website design because it has significant influence on the sales volume on a Website. This study focuses on product placement in designing product listing pages. Product placement concerns how venders of online stores place their products over the product listing pages for maximization of profit. This problem is very similar to the offline shelf management problem. Since product information sources on a Web page are typically communicated through the text and image, visual stimuli such as color, shape, size, and spatial arrangement often have an effect on the visual attention of online shoppers and, in turn, influence their eventual purchase decisions. In view of the above, this study synthesizes the visual attention literature and theory of shelf-space allocation to develop a mathematical programming model with genetic algorithms for finding optimal solutions to the focused issue. The validity of the model is illustrated with example problems.

A Temporal Locality-Aware Page-Mapped Flash Translation Layer

Energy Technology Data Exchange (ETDEWEB)

Kim, Youngjae [ORNL; Gupta, Aayush [IBM Corporation, Almaden Research Center; Urgaonkar, Bhuvan [Pennsylvania State University

2013-01-01

The poor performance of random writes has been a cause of major concern which needs to be addressed to better utilize the potential of flash in enterprise-scale environments. We examine one of the important causes of this poor performance: the design of the flash translation layer (FTL) which performs the virtual-to-physical address translations and hides the erase-before-write characteristics of flash. We propose a complete paradigm shift in the design of the core FTL engine from the existing techniques with our Demand-Based Flash Translation Layer (DFTL) which selectively caches page- level address mappings. Our experimental evaluation using FlashSim with realistic enterprise-scale workloads endorses the utility of DFTL in enterprise-scale storage systems by demonstrating: 1) improved performance, 2) reduced garbage collection overhead and 3) better overload behavior compared with hybrid FTL schemes which are the most popular implementation methods. For example, a predominantly random-write dominant I/O trace from an OLTP application running at a large financial institution shows a 78% improvement in average response time (due to a 3-fold reduction in operations of the garbage collector), compared with the hybrid FTL scheme. Even for the well-known read-dominant TPC-H benchmark, for which DFTL introduces additional overheads, we improve system response time by 56%. Moreover, interestingly, when write-back cache on DFTL-based SSD is enabled, DFTL even outperforms the page-based FTL scheme, improving their response time by 72% in Financial trace.

Beyond the electronic textbook model: software techniques to make on-line educational content dynamic.

Science.gov (United States)

Frank, M S; Dreyer, K

2001-06-01

We describe a working software technology that enables educators to incorporate their expertise and teaching style into highly interactive and Socratic educational material for distribution on the world wide web. A graphically oriented interactive authoring system was developed to enable the computer novice to create and store within a database his or her domain expertise in the form of electronic knowledge. The authoring system supports and facilitates the input and integration of several types of content, including free-form, stylized text, miniature and full-sized images, audio, and interactive questions with immediate feedback. The system enables the choreography and sequencing of these entities for display within a web page as well as the sequencing of entire web pages within a case-based or thematic presentation. Images or segments of text can be hyperlinked with point-and-click to other entities such as adjunctive web pages, audio, or other images, cases, or electronic chapters. Miniature (thumbnail) images are automatically linked to their full-sized counterparts. The authoring system contains a graphically oriented word processor, an image editor, and capabilities to automatically invoke and use external image-editing software such as Photoshop. The system works in both local area network (LAN) and internet-centric environments. An internal metalanguage (invisible to the author but stored with the content) was invented to represent the choreographic directives that specify the interactive delivery of the content on the world wide web. A database schema was developed to objectify and store both this electronic knowledge and its associated choreographic metalanguage. A database engine was combined with page-rendering algorithms in order to retrieve content from the database and deliver it on the web in a Socratic style, assess the recipient's current fund of knowledge, and provide immediate feedback, thus stimulating in-person interaction with a human expert

[The application of creative thinking teaching in nursing education].

Science.gov (United States)

Ku, Ya-Lie; Chang, Ching-Feng; Kuo, Chien-Lin; Sheu, Sheila

2010-04-01

Nursing education is increasingly expected to cultivate nursing student creative abilities in line with general Ministry of Education promotion of greater creativity within education and the greater leeway for creativity won domestically for nurses by professional nursing organizations. Creative thinking has been named by education experts in the United States as the third most important goal of nursing education. However, nursing students in Taiwan have been shown to test lower in terms of creativity than students enrolled in business management. Leaders in nursing education should consider methods by which to improve the creative thinking capabilities of nursing students. Articles in the literature indicate that courses in creative studies are concentrated in the field of education, with few designed specifically for nursing. The teaching of constructing creative thinking is particularly weak in the nursing field. The purpose of this article was to review literature on education and nursing in order to explore current definitions, teaching strategies, and evaluation approaches related to creativity, and to develop a foundation for teaching creativity in nursing. The authors hope that an appropriate creative thinking course for nursing students may be constructed by referencing guidance provided in this in order to further cultivate creative thinking abilities in nursing students that will facilitate their application of creative thinking in their future clinical practicum.

PageRank as a method to rank biomedical literature by importance.

Science.gov (United States)

Yates, Elliot J; Dixon, Louise C

2015-01-01

Optimal ranking of literature importance is vital in overcoming article overload. Existing ranking methods are typically based on raw citation counts, giving a sum of 'inbound' links with no consideration of citation importance. PageRank, an algorithm originally developed for ranking webpages at the search engine, Google, could potentially be adapted to bibliometrics to quantify the relative importance weightings of a citation network. This article seeks to validate such an approach on the freely available, PubMed Central open access subset (PMC-OAS) of biomedical literature. On-demand cloud computing infrastructure was used to extract a citation network from over 600,000 full-text PMC-OAS articles. PageRanks and citation counts were calculated for each node in this network. PageRank is highly correlated with citation count (R = 0.905, P PageRank can be trivially computed on commodity cluster hardware and is linearly correlated with citation count. Given its putative benefits in quantifying relative importance, we suggest it may enrich the citation network, thereby overcoming the existing inadequacy of citation counts alone. We thus suggest PageRank as a feasible supplement to, or replacement of, existing bibliometric ranking methods.

Computer-based applications aimed at youth and adults with intellectual disability for the development of support areas

Directory of Open Access Journals (Sweden)

Maria Esther BAÑOS GARCÍA

2018-03-01

Full Text Available The use of Information and Communication Technologies is widely spread in all fields, including education. In the case of young people and adults with intellectual disabilities, it seems obvious that applications should serve to improve those supports to provide in the different functional areas. In this manuscript, 56 computer applications, in English and/or in Spanish, have been found by means of the search and study of reviews, scientific articles and web pages. Then, its connection with the support areas was evaluated by identifying the link for each computer application with each of the nine support areas. The findings confirm that the digital divide continues to increase and, in some cases, the treatment of the proposed activities promoting a childlike picture of this group is maintained. We found a low level of awareness of the support areas among developers and an imbalance in the applications, since some areas have great coverage while others have a residual presence. Promoting the consideration of the support areas among developers and further training for both educators and youth and adults with intellectual disabilities in order to reach a more productive use of ICT is recommended.

What’s New? Deploying a Library New Titles Page with Minimal Programming

Directory of Open Access Journals (Sweden)

John Meyerhofer

2017-01-01

Full Text Available With a new titles web page, a library has a place to show faculty, students, and staff the items they are purchasing for their community. However, many times heavy programing knowledge and/or a LAMP stack (Linux, Apache, MySQL, PHP or APIs separate a library’s data from making a new titles web page a reality. Without IT staff, a new titles page can become nearly impossible or not worth the effort. Here we will demonstrate how a small liberal arts college took its acquisition data and combined it with a Google Sheet, HTML, and a little JavaScript to create a new titles web page that was dynamic and engaging to its users.

Formal telestroke training for neurovascular fellows (NVFs) is necessary because of growing use of telestroke technologies in the management of acute ischemic stroke; yet, educational approaches and training benchmarks are not formalized. Time between telestroke consultant page and tissue-type plasminogen activator administration (page-to-needle time, PTNT) can provide an objective measure of proficiency. We compared PTNT between NVFs and neurovascular attendings (NVAs) and evaluated changes in PTNT with experience. We identified suspected acute ischemic stroke patients in our telestroke registry from July 2013 to December 2015 who received tissue-type plasminogen activator. Using multivariable quantile regression, we estimated the difference and 95% confidence interval in median PTNT between NVFs and NVAs. We also report the coefficient of change in PTNT over increasing number of telestroke consults. NVFs evaluated 53.7% of 618 tissue-type plasminogen activator cases over telestroke. NVAs had significantly shorter PTNT compared with NVFs, with a difference in median PTNT of -9 minutes (95% confidence interval, -12.3 to -5.7). This difference persisted when adjusted for relative tissue-type plasminogen activator contraindications. For each additional telestroke consult, PTNT decreased by 0.07 minutes for NVFs or NVAs ( P =0.02 and importance of integrating telestroke training into supervised neurovascular fellowships to increase proficiency prior to independent practice and suggest that PTNT can be a benchmark for tracking proficiency. © 2017 American Heart Association, Inc.

"I didn't know her, but…": parasocial mourning of mediated deaths on Facebook RIP pages

Science.gov (United States)

Klastrup, Lisbeth

2015-04-01

This article examines the use of six Danish "Rest in Peace" or (RIP) memorial pages. The article focuses on the relation between news media and RIP page use, in relation to general communicative practices on these pages. Based on an analysis of press coverage of the deaths of six young people and a close analysis of 1,015 comments extracted from the RIP pages created to memorialize them, it is shown that their deaths attracted considerable media attention, as did the RIP pages themselves. Comment activity seem to reflect the news stories in the way the commenters refer to the context of death and the emotional distress they experience, but mainly comments on the RIP pages are conventional expressions of sympathy and "RIP" wishes. The article concludes that public RIP pages might be understood as virtual spontaneous shrines, affording an emerging practice of "RIP-ing."

Education has become a key component of any society since it is the means by which humanity functions and governs itself. It allows individuals to appropriately integrate into a given community. For this reason, new ways of interaction between students and educational contents are emerging in order to improve the quality of education. In this context, devices such as computers, smartphones, or electronic tablets represent new ways of accessing educational resources which do not limit students to their usage merely inside the classroom since these devices are available anywhere. Nowadays, television has become one of these technological tools able to support the teaching-learning process through documentary films or movies, among others. However, two main issues appear. First, some of these educational contents are not those needed by a professor since information is restricted, and second, the development of TV-based applications requires an integrative approach involving the support of several specialists in education who provide the guidelines needed to build high-quality contents, as well as application designers and developers who are able to deliver the educational applications demanded by students. This work presents a system called AthenaTV to generate android-based educational applications for TV. AthenaTV takes into account the 10-foot design scheme used by Google to develop interfaces based on interface design patterns established in Google TV, and it is based on the android development guidelines and HTML5 standard.

Evolving the Design of a Mobile Application to Support Transition to Tertiary Education

Directory of Open Access Journals (Sweden)

Yu Zhao

2017-11-01

Full Text Available Students’ transition to tertiary education plays a critical role in their overall post-secondary experience. Even though educational institutions have designed and implemented various transition support programs, most of them still struggle to collect detailed information and provide tailored and timely support to students. With the high adoption rate of smart phones among university students, mobile applications can be used as a platform to provide personalized support throughout the transition, which has the potential to address the shortcomings of existing programs. Moreover, the use of mobile applications to support the transition to tertiary education can benefit from emerging techniques to design applications to support individuals through transition processes. In this paper, we present the design and development process of myUniMate, a mobile application that allows students to track and reflect on information from multiple aspects of their university lives. The paper describes the user-centered design approach used in the design, the implementation process, and how the initial version evolved based on our previous study. We conducted a 4-week field trial with first year university students to validate our design.

An Evaluation of Contraception Education and Health Promotion Applications for Patients.

Science.gov (United States)

Lunde, Britt; Perry, Rachel; Sridhar, Aparna; Chen, Katherine T

Patients use mobile applications (apps) to obtain information about health, including contraception. Providers and health educators may also use apps designed for patients to aid in patient education during the clinical encounter or recommend apps for patient use. Individuals may have a difficult time remaining updated on the number and quality of available apps. The objective of this study is to identify and evaluate contraception apps for patient education and health promotion, so that providers and health educators may recommend accurate apps to patients. We systematically searched the Apple iTunes Store using contraception search terms. A master list of apps was created and the apps were divided into categories and subcategories according to intended audience and purpose. Contraception apps for patient education and health promotion were selected and also checked for availability in the Google Play Store. We evaluated these identified apps using an adapted APPLICATIONS scoring system. Forty-eight apps were identified from the original search. Nineteen of these were excluded because they did not open on an iPhone or iPad, were no longer available, or did not contain educational material on contraception. We excluded 11 additional apps that contained inaccurate information. We evaluated 18 apps. The mean score was 10.6 out of 17 possible points with a range of 7 to 15 points. Many apps provide contraception information for patients, but some apps are inaccurate. Few apps provide comprehensive information on all available methods, including effectiveness, side effects, and contraindications. Copyright © 2016 Jacobs Institute of Women's Health.

Full Text Available The relevance of local knowledge in cultural heritage is by now acknowledged. It helps to determine many community-based projects by identifying the material to be digitally maintained in multimedia collections provided by communities of volunteers, rather than for-profit businesses or government entities. Considering that the search and browsing of texts, images, video, and 3D models related to places is more essential than using a simple text-based search, an interactive multimedia map was implemented in this study. The map, which is loaded on a single HyperText Markup Language (HTML page using AJAX (Asynchronous JavaScript and XML, with a client-side control mechanism utilising jQuery components that are both freely available and ad-hoc developed, is updated according to user interaction. To simplify the publication of geo-referenced information, the application stores all the data in a Geographic JavaScript Object Notation (GeoJSON file rather than in a database. The multimedia contents—associated with the selected Points of Interest (PoIs—can be selected through text search and list browsing as well as by viewing their previews one by one in a sequence all together in a scrolling window (respectively: “Table”, “Folder”, and “Tile” functions. PoIs—visualised on the map with multi-shape markers using a set of unambiguous colours—can be filtered through their categories and types, accessibility status and timeline, thus improving the system usability. The map functions are illustrated using data collected in a Comenius project. Notes on the application software and architecture are also presented in this paper.

The Application of Crowd Sourcing in Educational Activities

Directory of Open Access Journals (Sweden)

Monika Skaržauskaitė

2012-07-01

Full Text Available Purpose—This paper analyses the role of crowdsourcing use in educational activities. In recent decades, the rapid growth of innovative Internet-based information and communication technologies created a new field of opportunities for educational organizations to reach their goals. Crowdsourcing, as defined by Jeff Howe (2006, is the act of taking a job traditionally performed by a designated employee and outsourcing it to an undefined, generally large group of people in the form of an open call. The newness of the term indicates that there is not significant literature on the subject of how this operating method is utilized in educational activities. The objective of this paper therefore is to take an exploratory look at how educational organizations are using crowdsourcing as part of their activities at the present time, and to suggest how the practice of crowdsourcing may spread to other educational activities as time goes on.Design/methodology/approach—The paper presents a conceptual model of crowdsourcing application in educational activities. The model is supported by analysis and synthesis of scientific literature and case studies.Findings—Analysis of literature and case studies allowed the creation of a conceptual model which shows the use of crowdsourcing in educational and supporting tasks of organizations. This tool will be helpful for future research on the subject, since it provides a framework of the analysis.Research limitations/implications—The model presented here is a conceptual model and needs to be validated empirically.Practical implications—For practical purposes, the variables proposed in the model would provide a more comprehensive framework for the assessment of crowdsourcing use in education activities and work as a guide for crowdsourcing strategies.Originality/Value—Although the relevant literature consists of many partial and indirect insights and indications in the direction as conceived by the model, the

PageFocus: Using paradata to detect and prevent cheating on online achievement tests.

Science.gov (United States)

Diedenhofen, Birk; Musch, Jochen

2017-08-01

Cheating threatens the validity of unproctored online achievement tests. To address this problem, we developed PageFocus, a JavaScript that detects when participants abandon test pages by switching to another window or browser tab. In a first study, we aimed at testing whether PageFocus could detect and prevent cheating. We asked 115 lab and 186 online participants to complete a knowledge test comprising items that were difficult to answer but easy to look up on the Internet. Half of the participants were invited to look up the solutions, which significantly increased their test scores. The PageFocus script detected test takers who abandoned the test page with very high sensitivity and specificity, and successfully reduced cheating by generating a popup message that asked participants not to cheat. In a second study, 510 online participants completed a knowledge test comprising items that could easily be looked up and a reasoning task involving matrices that were impossible to look up. In a first group, a performance-related monetary reward was promised to the top scorers; in a second group, participants took part in a lottery that provided performance-unrelated rewards; and in a third group, no incentive was offered. PageFocus revealed that participants cheated more when performance-related incentives were offered. As expected, however, this effect was limited to items that could easily be looked up. We recommend that PageFocus be routinely employed to detect and prevent cheating on online achievement tests.

Earth Science Data and Applications for K-16 Education from the NASA Langley Atmospheric Science Data Center

Science.gov (United States)

Phelps, C. S.; Chambers, L. H.; Alston, E. J.; Moore, S. W.; Oots, P. C.

2005-05-01

NASA's Science Mission Directorate aims to stimulate public interest in Earth system science and to encourage young scholars to consider careers in science, technology, engineering and mathematics. NASA's Atmospheric Science Data Center (ASDC) at Langley Research Center houses over 700 data sets related to Earth's radiation budget, clouds, aerosols and tropospheric chemistry that are being produced to increase academic understanding of the natural and anthropogenic perturbations that influence global climate change. However, barriers still exist in the use of these actual satellite observations by educators in the classroom to supplement the educational process. Thus, NASA is sponsoring the "Mentoring and inquirY using NASA Data on Atmospheric and earth science for Teachers and Amateurs" (MY NASA DATA) project to systematically support educational activities by reducing the ASDC data holdings to `microsets' that can be easily accessible and explored by the K-16 educators and students.

2016-03-25

Biomedical science, especially biomaterials, is an expanding field in medicine. Universities are being challenged to gain the best students for a later academic career. Pre-university assessment of pupils has become crucial to reach this aim. Blended learning is an emerging paradigm for science education even though it has not yet been rigorously assessed, especially in the pupil/undergraduate situation. The aim of the study was to develop and preliminarily test a blended-learning system in biomedicine for university applicants. An internet-based blended-learning module in material science was developed in close collaboration between a university (Biomaterials Department, Dresden TU), a German Gymnasium and an internationally oriented medical college (IMC®, Münster). Forty pre-university students were taught by this learning module composed of school education and internet-based knowledge transfer and involved in the evaluation of the utility of this learning tool. Finally, the students took first-year university examinations in order to evaluate the success of this kind of education. The internet-based blended-learning module as a combination of e-learning tutorials and live online lectures which was applied in phase 3 of this study was developed on the basis of the findings of both pre-university studies. The results of the learning behavior regarding the number of invokes and the dwell time of the individual pages of the pre-university learning material, the results of the online evaluation and the results of the pre-phase examination were successively used to optimize the next phase. At the end of the pre-university learning, seven of eight participants were able to pass the first-year university examination followed by nationally accepted credit award. Internet-based blended-learning module proved to be suitable to prepare students for biomedical university education while also giving them the possibility to assess their qualifications for studying

The LHCb is one of the main detectors of Large Hadron Collider, where physicists and scientists work together on high precision measurements of matter-antimatter asymmetries and searches for rare and forbidden decays, with the aim of discovering new and unexpected forces. The work does not only consist of analyzing data collected from experiments but also in publishing the results of those analyses. The LHCb publications are gathered on LHCb publications page to maximize their availability to both LHCb members and to the high energy community. In this project a new database system was implemented for LHCb publications page. This will help to improve access to research papers for scientists and better integration with current CERN library website and others.

Discovering urban mobility patterns with PageRank based traffic modeling and prediction

Science.gov (United States)

Wang, Minjie; Yang, Su; Sun, Yi; Gao, Jun

2017-11-01

Urban transportation system can be viewed as complex network with time-varying traffic flows as links to connect adjacent regions as networked nodes. By computing urban traffic evolution on such temporal complex network with PageRank, it is found that for most regions, there exists a linear relation between the traffic congestion measure at present time and the PageRank value of the last time. Since the PageRank measure of a region does result from the mutual interactions of the whole network, it implies that the traffic state of a local region does not evolve independently but is affected by the evolution of the whole network. As a result, the PageRank values can act as signatures in predicting upcoming traffic congestions. We observe the aforementioned laws experimentally based on the trajectory data of 12000 taxies in Beijing city for one month.

La double-page chez Hirohiko Araki : l’ubris faite norme

Directory of Open Access Journals (Sweden)

Aurélien Pigeat

2011-03-01

Full Text Available Le style d’Araki se caractérise par un usage massif de la double-page, loin de l’usage ponctuel que l’on trouve habituellement dans les shonen. Elle témoigne d’une forme d’ubris qui se fait norme de composition c’est-à-dire qu’elle érige le principe de débordement en règle de structuration de l’action et des planches Elle est ainsi la marque de la démesure d’un auteur qui, sous l’apparence du manga populaire, et à travers les codes de ce dernier, élabore une œuvre d’une puissance et d’une sophistication rares..

Pour appréhender ce phénomène, il nous faut d’abord observer concrètement l’usage que fait Hirohiko Araki de la double-page, les lieux du récit que celle-ci investit, la fréquence de ses manifestations, et la manière dont elle caractérise les différentes parties de la saga Jojo’s bizarre Adventure. L’ubris de la double-page met alors particulièrement en relief deux éléments centraux de la poétique d’Hirohiko Araki : le corps et le temps.  La double-page apparaît comme la réponse matérielle à ces corps qui débordent de la page classique, qui éclatent ou se dispersent de telle sorte que l’auteur doit étendre les limites de ce cadre pour les représenter. Le temps entre lui en scène à travers le détail : la double-page devient le règne d’un détail sur lequel le lecteur passe trop vite et auquel le héros accorde toute son attention. Enfin, la double-page possède chez Hirohiko Araki une dimension proprement esthétique que révèle clairement l’usage presque absolu qui en est fait dans la septième partie de Jojo’s bizarre Adventure, Steel Ball Run, et dans le volume Rohan au Louvre, même si l’on peut la deviner déjà auparavant. La double-page est un moment où l’énigme se présente au héros, se met en mouvement ou se trouve élucidée. Le règne de l’ubris s’affirme là, dans ces doubles-pages qui n’en sont finalement plus, dans cette

Suzuki, Lalita K; Beale, Ivan L

2006-01-01

The content of personal Web home pages created by adolescents with cancer is a new source of information about this population of potential benefit to oncology nurses and psychologists. Individual Internet elements found on 21 home pages created by youths with cancer (14-22 years old) were rated for cancer-related self-presentation, information dissemination, and interpersonal connection. Examples of adolescents' online narratives were also recorded. Adolescents with cancer used various Internet elements on their home pages for cancer-related self-presentation (eg, welcome messages, essays, personal history and diary pages, news articles, and poetry), information dissemination (e.g., through personal interest pages, multimedia presentations, lists, charts, and hyperlinks), and interpersonal connection (eg, guestbook entries). Results suggest that various elements found on personal home pages are being used by a limited number of young patients with cancer for self-expression, information access, and contact with peers.

in real-time via the Seismographs in Schools API. This API allows anyone to extract data, re-purpose it, and display it in various ways. This gives educators the ability to build applications on top of the IRIS Seismographs in Schools Website and also lowers the barrier for teachers who want to create their own regional school seismology networks. Recent seismic data are also provided to general audiences via our museum displays. Millions of people have interacted with IRIS/USGS museum displays, many of them at the American Museum of Natural History in New York and the Smithsonian Institution National Museum of Natural History in Washington, D.C. However, a growing number of people explore seismological concepts and near real-time data through our newest display, the Active Earth Display (AED). The AED is a smaller, more flexible version of the museum display, and is now in use at universities and visitor centers throughout the US. Served via a web browser, the display is customizable and the software is available to anyone who applies via the IRIS E&O web pages. Touch screens provide an interactive experience and new content continues to be developed, including new sets of pages focusing on the Cascadia and Basin and Range regions.

A scrutiny of the educational value of EFL mobile learning applications

Directory of Open Access Journals (Sweden)

Cristina Calle Martínez

2014-08-01

Full Text Available Mobile learning is without any doubt the next step in the evolution of educational technology as it offers modern methods of support to the process of learning through the use of mobile instruments. However, although there are a huge number of educational applications in the market at the moment, the educational value of many of them is rather questionable. The final aim of the SO-CALL-ME ((Social Ontology-based Cognitively Augmented Language Learning Mobile Environment (FFI 2011-29829 research project is to design and create EFL mobile applications that successfully combine technical skills and a solid pedagogy. In this light, the present study is the third phase of a line of research which started in 2012. In the first phase 67 MALL applications in the context of EFL were assessed by means of a rubric not on their technical features but on their pedagogic goals. The results gave us an idea of the qualities and limitations of the apps examined. In the second phase, a quality guide was created as the basis for a more elaborate evaluation rubric. Out of the EFL apps previously analyzed with the first rubric, we chose four that fulfilled the features considered most important for the apps to be developed in a final stage of the research project. In the third phase, a rubric was used to evaluate the linguistic adequacy of EFL apps for listening. The present study offers the evaluation of a higher number of apps using the rubrics created in phases 2 and 3 in order to corroborate the first impressions as a final step before using the quality guide for the creation of EFL applications.

Picariello, Gianluca; De Martino, Alessandra; Mamone, Gianfranco; Ferranti, Pasquale; Addeo, Francesco; Faccia, Michele; Spagnamusso, Salvatore; Di Luccia, Aldo

2006-03-20

In the present study, an alternative procedure for two-dimensional (2D) electrophoretic analysis in proteomic investigation of the most represented basic muscle water-soluble proteins is suggested. Our method consists of Acetic acid-Urea-Triton polyacrylamide gel (AUT-PAGE) analysis in the first dimension and standard sodium dodecyl sulphate polyacrylamide gel (SDS-PAGE) in the second dimension. Although standard two-dimensional Immobilized pH Gradient-Sodium Dodecyl-Sulphate (2D IPG-SDS) gel electrophoresis has been successfully used to study these proteins, most of the water-soluble proteins are spread on the alkaline part of the 2D map and are poorly focused. Furthermore, the similarity in their molecular weights impairs resolution of the classical approach. The addition of Triton X-100, a non-ionic detergent, into the gel induces a differential electrophoretic mobility of proteins as a result of the formation of mixed micelles between the detergent and the hydrophobic moieties of polypeptides, separating basic proteins with a criterion similar to reversed phase chromatography based on their hydrophobicity. The acid pH induces positive net charges, increasing with the isoelectric point of proteins, thus allowing enhanced resolution in the separation. By using 2D AUT-PAGE/SDS electrophoresis approach to separate water-soluble proteins from fresh pork and from dry-cured products, we could spread proteins over a greater area, achieving a greater resolution than that obtained by IPG in the pH range 3-10 and 6-11. Sarcoplasmic proteins undergoing proteolysis during the ripening of products were identified by Matrix Assisted Laser Desorption/Ionization-Time of Flight (MALDI-ToF) mass spectrometry peptide mass fingerprinting in a easier and more effective way. Two-dimensional AUT-PAGE/SDS electrophoresis has allowed to simplify separation of sarcoplasmic protein mixtures making this technique suitable in the defining of quality of dry-cured pork products by immediate

The Application of Crowd Sourcing in Educational Activities

Directory of Open Access Journals (Sweden)

Monika Skaržauskaitė

2013-01-01

Full Text Available Purpose—This paper analyses the role of crowdsourcing use in educational activities. In recent decades, the rapid growth of innovative Internet-based information and communication technologies created a new field of opportunities for educational organizations to reach their goals. Crowdsourcing, as defined by Jeff Howe (2006, is the act of taking a job traditionally performed by a designated employee and outsourcing it to an undefined, generally large group of people in the form of an open call. The newness of the term indicates that there is not significant literature on the subject of how this operating method is utilized in educational activities. The objective of this paper therefore is to take an exploratory look at how educational organizations are using crowdsourcing as part of their activities at the present time, and to suggest how the practice of crowdsourcing may spread to other educational activities as time goes on. Design/methodology/approach—The paper presents a conceptual model of crowdsourcing application in educational activities. The model is supported by analysis and synthesis of scientific literature and case studies. Findings—Analysis of literature and case studies allowed the creation of a conceptual model which shows the use of crowdsourcing in educational and supporting tasks of organizations. This tool will be helpful for future research on the subject, since it provides a framework of the analysis. Research limitations/implications—The model presented here is a conceptual model and needs to be validated empirically. Practical implications—For practical purposes, the variables proposed in the model would provide a more comprehensive framework for the assessment of crowdsourcing use in education activities and work as a guide for crowdsourcing strategies. Originality/Value—Although the relevant literature consists of many partial and indirect insights and indications in the direction as conceived by the model

Deaf or hard-of-hearing children experience difficulties in learning health principles. But technology has significantly improved their ability to learn. The challenge in e-learning is to design attractive applications while having an educational aspect. The aims of this study were to determine the pedagogical effectiveness of a health education application for deaf and hard of hearing students in elementary schools, and to investigate the student's perceptions in different educational grades about the educational effectiveness of the text, graphics, video clips, and animation in the application. The study design was quasi experimental and was conducted in Mashhad in 2016. Study population were deaf or hard-of-hearing students in elementary schools. The intervention included health application training to deaf and hard-of-hearing students in Mashhad. A questionnaire was used for data gathering. The pedagogical effectiveness was determined by measuring the modified Adapted Pedagogical Index. This index was created based on the characteristics of the application and study population. Statistical analysis was performed using the Kruskal-Wallis and Mann-Whitney tests with Bonferroni adjustment by SPSS 22. Eighty-two students participated in the intervention. The value of modified Adapted Pedagogical Index was 0.669, indicating that the application was effective. The results of Kruskal-Wallis H and Mann-Whitney U test showed significant differences in different educational grades. (pinformation technology can improve the education of deaf and hard-of-hearing students. Modified Adapted Pedagogical Index can be used for evaluation of non-interactive applications for elementary school children who are deaf or hard of hearing.

This mechanism is based on a simple and well-known initiative in the field of the health-related web, the HONcode. The Resource Description Framework (RDF) format and the Dublin Core Metadata Element Set were used to formalize these metadata. The model of trust proposed is based on a quality model for health-related web pages that has been tested in practice over a period of thirteen years. Our model has been explored in the context of a project to develop a research tool that automatically detects the occurrence of quality criteria in health-related web pages.

Identification of Malicious Web Pages by Inductive Learning

Science.gov (United States)

Liu, Peishun; Wang, Xuefang

Malicious web pages are an increasing threat to current computer systems in recent years. Traditional anti-virus techniques focus typically on detection of the static signatures of Malware and are ineffective against these new threats because they cannot deal with zero-day attacks. In this paper, a novel classification method for detecting malicious web pages is presented. This method is generalization and specialization of attack pattern based on inductive learning, which can be used for updating and expanding knowledge database. The attack pattern is established from an example and generalized by inductive learning, which can be used to detect unknown attacks whose behavior is similar to the example.

Online information can influence attitudes toward vaccination. The aim of the present study was to provide a systematic evaluation of the search engine ranking, quality, and content of Web pages that are critical versus noncritical of human papillomavirus (HPV) vaccination. We identified HPV vaccine-related Web pages with the Google search engine by entering 20 terms. We then assessed each Web page for critical versus noncritical bias and for the following quality indicators: authorship disclosure, source disclosure, attribution of at least one reference, currency, exclusion of testimonial accounts, and readability level less than ninth grade. We also determined Web page comprehensiveness in terms of mention of 14 HPV vaccine-relevant topics. Twenty searches yielded 116 unique Web pages. HPV vaccine-critical Web pages comprised roughly a third of the top, top 5- and top 10-ranking Web pages. The prevalence of HPV vaccine-critical Web pages was higher for queries that included term modifiers in addition to root terms. Compared with noncritical Web pages, Web pages critical of HPV vaccine overall had a lower quality score than those with a noncritical bias (p engine queries despite being of lower quality and less comprehensive than noncritical Web pages.

Web pages: What can you see in a single fixation?

Science.gov (United States)

Jahanian, Ali; Keshvari, Shaiyan; Rosenholtz, Ruth

2018-01-01

Research in human vision suggests that in a single fixation, humans can extract a significant amount of information from a natural scene, e.g. the semantic category, spatial layout, and object identities. This ability is useful, for example, for quickly determining location, navigating around obstacles, detecting threats, and guiding eye movements to gather more information. In this paper, we ask a new question: What can we see at a glance at a web page - an artificial yet complex "real world" stimulus? Is it possible to notice the type of website, or where the relevant elements are, with only a glimpse? We find that observers, fixating at the center of a web page shown for only 120 milliseconds, are well above chance at classifying the page into one of ten categories. Furthermore, this ability is supported in part by text that they can read at a glance. Users can also understand the spatial layout well enough to reliably localize the menu bar and to detect ads, even though the latter are often camouflaged among other graphical elements. We discuss the parallels between web page gist and scene gist, and the implications of our findings for both vision science and human-computer interaction.

Bera, Maitreyee

2017-10-16

The U.S. Geological Survey (USGS), in cooperation with the DuPage County Stormwater Management Department, maintains a database of hourly meteorological and hydrologic data for use in a near real-time streamflow simulation system. This system is used in the management and operation of reservoirs and other flood-control structures in the West Branch DuPage River watershed in DuPage County, Illinois. The majority of the precipitation data are collected from a tipping-bucket rain-gage network located in and near DuPage County. The other meteorological data (air temperature, dewpoint temperature, wind speed, and solar radiation) are collected at Argonne National Laboratory in Argonne, Ill. Potential evapotranspiration is computed from the meteorological data using the computer program LXPET (Lamoreux Potential Evapotranspiration). The hydrologic data (water-surface elevation [stage] and discharge) are collected at U.S.Geological Survey streamflow-gaging stations in and around DuPage County. These data are stored in a Watershed Data Management (WDM) database.This report describes a version of the WDM database that is quality-assured and quality-controlled annually to ensure datasets are complete and accurate. This database is named WBDR13.WDM. It contains data from January 1, 2007, through September 30, 2013. Each precipitation dataset may have time periods of inaccurate data. This report describes the methods used to estimate the data for the periods of missing, erroneous, or snowfall-affected data and thereby improve the accuracy of these data. The other meteorological datasets are described in detail in Over and others (2010), and the hydrologic datasets in the database are fully described in the online USGS annual water data reports for Illinois (U.S. Geological Survey, 2016) and, therefore, are described in less detail than the precipitation datasets in this report.

Does content affect whether users remember that Web pages were hyperlinked?

Science.gov (United States)

Jones, Keith S; Ballew, Timothy V; Probst, C Adam

2008-10-01

We determined whether memory for hyperlinks improved when they represented relations between the contents of the Web pages. J. S. Farris (2003) found that memory for hyperlinks improved when they represented relations between the contents of the Web pages. However, Farris's (2003) participants could have used their knowledge of site content to answer questions about relations that were instantiated via the site's content and its hyperlinks. In Experiment 1, users navigated a Web site and then answered questions about relations that were instantiated only via content, only via hyperlinks, and via content and hyperlinks. Unlike Farris (2003), we split the latter into two sets. One asked whether certain content elements were related, and the other asked whether certain Web pages were hyperlinked. Experiment 2 replicated Experiment 1 with one modification: The questions that were asked about relations instantiated via content and hyperlinks were changed so that each question's wrong answer was also related to the question's target. Memory for hyperlinks improved when they represented relations instantiated within the content of the Web pages. This was true when (a) questions about content and hyperlinks were separated (Experiment 1) and (b) each question's wrong answer was also related to the question's target (Experiment 2). The accuracy of users' mental representations of local architecture depended on whether hyperlinks were related to the site's content. Designers who want users to remember hyperlinks should associate those hyperlinks with content that reflects the relation between the contents on the Web pages.

Rajput, A.Q.K.; Shaikh, M.Z.; Khanzada, T.J.S.

2003-01-01

Holographic environment is based on high-equipped Multimedia information systems. These are based on the evolving powers of computers to handle huge volume of information. Holographic environment is a simulated environment that allows the user to touch and interact with projections, which are derived from the distant real environment. A new communications technology is being developed that will facilitate to interact inside a simulated environment, even if you are thousands of miles apart. This is done with enhancing the electro-holography, which is the computer based generation of diffraction fringes from 3D input data and the display of the reconstructed object in real-time. This research paper presents the design and development of holographic environment for reduction of distances in business and educational applications. The Holographic Environment development with the use of multimedia information systems is discussed. In Particular the characteristics of holographic data and the current research results in the area of real time holographic display systems are spanned. The Technical components of holographic system are also encountered. Finally, issues of improvement in efficiency of Holographic Environments by compression of data are presented along with its utilization for educational and business applications. (author)

Digital libraries and World Wide Web sites and page persistence.

Directory of Open Access Journals (Sweden)

Wallace Koehler

1999-01-01

Full Text Available Web pages and Web sites, some argue, can either be collected as elements of digital or hybrid libraries, or, as others would have it, the WWW is itself a library. We begin with the assumption that Web pages and Web sites can be collected and categorized. The paper explores the proposition that the WWW constitutes a library. We conclude that the Web is not a digital library. However, its component parts can be aggregated and included as parts of digital library collections. These, in turn, can be incorporated into "hybrid libraries." These are libraries with both traditional and digital collections. Material on the Web can be organized and managed. Native documents can be collected in situ, disseminated, distributed, catalogueed, indexed, controlled, in traditional library fashion. The Web therefore is not a library, but material for library collections is selected from the Web. That said, the Web and its component parts are dynamic. Web documents undergo two kinds of change. The first type, the type addressed in this paper, is "persistence" or the existence or disappearance of Web pages and sites, or in a word the lifecycle of Web documents. "Intermittence" is a variant of persistence, and is defined as the disappearance but reappearance of Web documents. At any given time, about five percent of Web pages are intermittent, which is to say they are gone but will return. Over time a Web collection erodes. Based on a 120-week longitudinal study of a sample of Web documents, it appears that the half-life of a Web page is somewhat less than two years and the half-life of a Web site is somewhat more than two years. That is to say, an unweeded Web document collection created two years ago would contain the same number of URLs, but only half of those URLs point to content. The second type of change Web documents experience is change in Web page or Web site content. Again based on the Web document samples, very nearly all Web pages and sites undergo some

Calibrating page sized Gafchromic EBT3 films

International Nuclear Information System (INIS)

Crijns, W.; Maes, F.; Heide, U. A. van der; Van den Heuvel, F.

2013-01-01

Purpose: The purpose is the development of a novel calibration method for dosimetry with Gafchromic EBT3 films. The method should be applicable for pretreatment verification of volumetric modulated arc, and intensity modulated radiotherapy. Because the exposed area on film can be large for such treatments, lateral scan errors must be taken into account. The correction for the lateral scan effect is obtained from the calibration data itself. Methods: In this work, the film measurements were modeled using their relative scan values (Transmittance, T). Inside the transmittance domain a linear combination and a parabolic lateral scan correction described the observed transmittance values. The linear combination model, combined a monomer transmittance state (T 0 ) and a polymer transmittance state (T ∞ ) of the film. The dose domain was associated with the observed effects in the transmittance domain through a rational calibration function. On the calibration film only simple static fields were applied and page sized films were used for calibration and measurements (treatment verification). Four different calibration setups were considered and compared with respect to dose estimation accuracy. The first (I) used a calibration table from 32 regions of interest (ROIs) spread on 4 calibration films, the second (II) used 16 ROIs spread on 2 calibration films, the third (III), and fourth (IV) used 8 ROIs spread on a single calibration film. The calibration tables of the setups I, II, and IV contained eight dose levels delivered to different positions on the films, while for setup III only four dose levels were applied. Validation was performed by irradiating film strips with known doses at two different time points over the course of a week. Accuracy of the dose response and the lateral effect correction was estimated using the dose difference and the root mean squared error (RMSE), respectively. Results: A calibration based on two films was the optimal balance between

Going, going, still there: using the WebCite service to permanently archive cited web pages.

Science.gov (United States)

Eysenbach, Gunther; Trudel, Mathieu

2005-12-30

Scholars are increasingly citing electronic "web references" which are not preserved in libraries or full text archives. WebCite is a new standard for citing web references. To "webcite" a document involves archiving the cited Web page through www.webcitation.org and citing the WebCite permalink instead of (or in addition to) the unstable live Web page. This journal has amended its "instructions for authors" accordingly, asking authors to archive cited Web pages before submitting a manuscript. Almost 200 other journals are already using the system. We discuss the rationale for WebCite, its technology, and how scholars, editors, and publishers can benefit from the service. Citing scholars initiate an archiving process of all cited Web references, ideally before they submit a manuscript. Authors of online documents and websites which are expected to be cited by others can ensure that their work is permanently available by creating an archived copy using WebCite and providing the citation information including the WebCite link on their Web document(s). Editors should ask their authors to cache all cited Web addresses (Uniform Resource Locators, or URLs) "prospectively" before submitting their manuscripts to their journal. Editors and publishers should also instruct their copyeditors to cache cited Web material if the author has not done so already. Finally, WebCite can process publisher submitted "citing articles" (submitted for example as eXtensible Markup Language [XML] documents) to automatically archive all cited Web pages shortly before or on publication. Finally, WebCite can act as a focussed crawler, caching retrospectively references of already published articles. Copyright issues are addressed by honouring respective Internet standards (robot exclusion files, no-cache and no-archive tags). Long-term preservation is ensured by agreements with libraries and digital preservation organizations. The resulting WebCite Index may also have applications for research

“I didn't know her, but…”: parasocial mourning of mediated deaths on Facebook RIP pages

DEFF Research Database (Denmark)

Klastrup, Lisbeth

2015-01-01

This article examines the use of six Danish “Rest in Peace” or (RIP) memorial pages. The article focuses on the relation between news media and RIP page use, in relation to general communicative practices on these pages. Based on an analysis of press coverage of the deaths of six young people...... and a close analysis of 1,015 comments extracted from the RIP pages created to memorialize them, it is shown that their deaths attracted considerable media attention, as did the RIP pages themselves. Comment activity seem to reflect the news stories in the way the commenters refer to the context of death...... and the emotional distress they experience, but mainly comments on the RIP pages are conventional expressions of sympathy and “RIP” wishes. The article concludes that public RIP pages might be understood as virtual spontaneous shrines, affording an emerging practice of “RIP-ing.”...

Intention to continue using Facebook fan pages from the perspective of social capital theory.

Science.gov (United States)

Lin, Kuan-Yu; Lu, Hsi-Peng

2011-10-01

Social network sites enable users to express themselves, establish ties, and develop and maintain social relationships. Recently, many companies have begun using social media identity (e.g., Facebook fan pages) to enhance brand attractiveness, and social network sites have evolved into social utility networks, thereby creating a number of promising business opportunities. To this end, the operators of fan pages need to be aware of the factors motivating users to continue their patronization of such pages. This study set out to identify these motivating factors from the point of view of social capital. This study employed structural equation modeling to investigate a research model based on a survey of 327 fan pages users. This study discovered that ties related to social interaction (structural dimension), shared values (cognitive dimension), and trust (relational dimension) play important roles in users' continued intention to use Facebook fan pages. Finally, this study discusses the implications of these findings and offers directions for future research.

Document representations for classification of short web-page descriptions

Directory of Open Access Journals (Sweden)

Radovanović Miloš

2008-01-01

Full Text Available Motivated by applying Text Categorization to classification of Web search results, this paper describes an extensive experimental study of the impact of bag-of- words document representations on the performance of five major classifiers - Naïve Bayes, SVM, Voted Perceptron, kNN and C4.5. The texts, representing short Web-page descriptions sorted into a large hierarchy of topics, are taken from the dmoz Open Directory Web-page ontology, and classifiers are trained to automatically determine the topics which may be relevant to a previously unseen Web-page. Different transformations of input data: stemming, normalization, logtf and idf, together with dimensionality reduction, are found to have a statistically significant improving or degrading effect on classification performance measured by classical metrics - accuracy, precision, recall, F1 and F2. The emphasis of the study is not on determining the best document representation which corresponds to each classifier, but rather on describing the effects of every individual transformation on classification, together with their mutual relationships. .

One major criterion for the success of this technology has always been the education and training of competent personnel in all sectors of nuclear development and application. The high level of competence and know-how reached must be maintained in the future. Qualified personnel is required for running existing plants, building new nuclear power plants - at present especially in Japan and Korea - and for all activities associated with supply and waste management, decommissioning, and for all applications of nuclear technology above and beyond energy generation. The number of university graduates in the OECD countries is decreasing alarmingly, among other reasons because of the diminished attractiveness of these courses as a consequence of the reduced number of nuclear engineering courses offered in curricula. A broad-based program of disseminating basic information in nuclear technology in university curricula is urgently required. In industry, internal advanced and in-career training measures and programs are offered to ensure broad-based qualification as well as specialization in nuclear subjects of the staff, as demands are rising and flexibility is required of all staff members. This development implies that governments in particular are called upon to ensure, by long-term planning, that nuclear competence is preserved in science and research, in industry and applications, as part of their areas of responsibility and competence.

The increased popularity of the web has caused the inclusion of huge amount of information to the web, and as a result of this explosive information growth, automated web page classification systems are needed to improve search engines' performance. Web pages have a large number of features such as HTML/XML tags, URLs, hyperlinks, and text contents that should be considered during an automated classification process. The aim of this study is to reduce the number of features to be used to improve runtime and accuracy of the classification of web pages. In this study, we used an ant colony optimization (ACO) algorithm to select the best features, and then we applied the well-known C4.5, naive Bayes, and k nearest neighbor classifiers to assign class labels to web pages. We used the WebKB and Conference datasets in our experiments, and we showed that using the ACO for feature selection improves both accuracy and runtime performance of classification. We also showed that the proposed ACO based algorithm can select better features with respect to the well-known information gain and chi square feature selection methods.

Application of Project Portfolio Management

Pankowska, Malgorzata

The main goal of the chapter is the presentation of the application project portfolio management approach to support development of e-Municipality and public administration information systems. The models of how people publish and utilize information on the web have been transformed continually. Instead of simply viewing on static web pages, users publish their own content through blogs and photo- and video-sharing slides. Analysed in this chapter, ICT (Information Communication Technology) projects for municipalities cover the mixture of the static web pages, e-Government information systems, and Wikis. So, for the management of the ICT projects' mixtures the portfolio project management approach is proposed.
