EVpedia: A community web portal for extracellular vesicles research

Motivation Extracellular vesicles (EVs) are spherical bilayered proteolipids, harboring various bioactive molecules. Due to the complexity of the vesicular nomenclatures and components, online searches for EV-related publications and vesicular components are currently challenging. Results We present an improved version of EVpedia, a public database for EVs research. This community web portal contains a database of publications and vesicular components, identification of orthologous vesicular components, bioinformatic tools and a personalized function. EVpedia includes 6879 publications, 172 080 vesicular components from 263 high-throughput datasets, and has been accessed more than 65 000 times from more than 750 cities. In addition, about 350 members from 73 international research groups have participated in developing EVpedia. This free web-based database might serve as a useful resource to stimulate the emerging field of EV research. Availability and implementation The web site was implemented in PHP, Java, MySQL and Apache, and is freely available at http://evpedia.info.

Do diabetic veterans use the Internet? Self-reported usage, skills, and interest in using My HealtheVet Web portal.

OBJECTIVE: The Veterans Health Administration has developed My HealtheVet (MHV), a Web-based portal that links veterans to their care in the veteran affairs (VA) system. The objective of this study was to measure diabetic veterans' access to and use of the Internet, and their interest in using MHV to help manage their diabetes. MATERIALS AND METHODS: Cross-sectional mailed survey of 201 patients with type 2 diabetes and hemoglobin A(1c) > 8.0% receiving primary care at any of five primary care clinic sites affiliated with a VA tertiary care facility. Main measures included Internet usage, access, and attitudes; computer skills; interest in using the Internet; awareness of and attitudes toward MHV; demographics; and socioeconomic status. RESULTS: A majority of respondents reported having access to the Internet at home. Nearly half of all respondents had searched online for information about diabetes, including some who did not have home Internet access. More than a third obtained "some" or "a lot" of their health-related information online. Forty-one percent reported being "very interested" in using MHV to help track their home blood glucose readings, a third of whom did not have home Internet access. Factors associated with being "very interested" were as follows: having access to the Internet at home (p < 0.001), "a lot/some" trust in the Internet as a source of health information (p = 0.002), lower age (p = 0.03), and some college (p = 0.04). Neither race (p = 0.44) nor income (p = 0.25) was significantly associated with interest in MHV. CONCLUSIONS: This study found that a diverse sample of older VA patients with sub-optimally controlled diabetes had a level of familiarity with and access to the Internet comparable to an age-matched national sample. In addition, there was a high degree of interest in using the Internet to help manage their diabetes.

A lightweight supercomputing web portal for inferring phylogenetic trees

In this paper we describe a lightweight Web portal developed for running computational jobs on a IBM JS21 Bladecenter cluster, ThamesBlue, for inferring and analyzing evolutionary histories. We first discuss the need for leveraging HPC as a enabler for molecular phylogenetics research. We go on to describe how the portal is designed to interface with existing open-source software that is typical of a HPC resource configuration, and how by design this portal is generic enough to be portable to other similarly configured compute clusters, and for other applications.

An ECOOP web portal for visualising and comparing distributed coastal oceanography model and in situ data

As part of a large European coastal operational oceanography project (ECOOP), we have developed a web portal for the display and comparison of model and in situ marine data. The distributed model and in situ datasets are accessed via an Open Geospatial Consortium Web Map Service (WMS) and Web Feature Service (WFS) respectively. These services were developed independently and readily integrated for the purposes of the ECOOP project, illustrating the ease of interoperability resulting from adherence to international standards. The key feature of the portal is the ability to display co-plotted timeseries of the in situ and model data and the quantification of misfits between the two. By using standards-based web technology we allow the user to quickly and easily explore over twenty model data feeds and compare these with dozens of in situ data feeds without being concerned with the low level details of differing file formats or the physical location of the data. Scientific and operational benefits to this work include model validation, quality control of observations, data assimilation and decision support in near real time. In these areas it is essential to be able to bring different data streams together from often disparate locations.

EST-PAC HPC - a web portal for high-throughput EST annotation and protein sequence prediction

Expressed Sequence Tags (ESTs) are short DNA sequences generated by sequencing the transcribed cDNAs coming from a gene expression. They can provide significant functional, structural and evolutionary information and thus are a primary resource for gene discovery. EST annotation basically refers to the analysis of unknown ESTs that can be performed by database similarity search for possible identities and database search for functional prediction of translation products. Such kind of annotation typically consists of a series of repetitive tasks which should be automated, and be customizable and amenable to using distributed computing resources. Furthermore, processing of EST data should be done efficiently using a high performance computing platform. In this paper, we describe an EST annotator, EST-PACHPC, which has been developed for harnessing HPC resources potentially from Grid and Cloud systems for high throughput EST annotations. The performance analysis of EST-PACHPC has shown that it provides substantial performance gain in EST annotation.

Integrating social media tools in a web portal

Benefitting from Web 2.0 features, Social Media allows organisations to be where the users are, creating proximity, talking to them, and knowing what they want. Going viral and word-of-mouth become easier, as these platforms allow us to share, to like, and to use multimedia and convergence – as they can interact with each other, communicating on a large scale. Given that online portals provide for a highly competitive environment, players strive to get more visits, better search rankings, and even aspire to be the homepage for the Web universe. We discuss the integration of Social Media tools in a Web Portal, and explore how using these together may improve the competitiveness of a Web Portal. A large Web Portal was selected to develop this case study. We found that, although for this particular Web Portal conditions were created to accommodate and integrate the chosen Social Media platforms, this was done in an organic and fluid way, with great focus on community construction and less focus on absorptive capacity. Based on the findings of this case study, we propose a dynamic cycle of benefits for integrating Social Media tools in a Web Portal.

Democracia eletrônica para quem? : Quem são, o que querem e como os cidadãos avaliam o portal da Câmara dos Deputados

A dissertação busca responder em que medida todas as possibilidades de interação ofertadas pelo Portal da Câmara dos Deputados atendem às necessidades de interação política dos cidadãos que utilizam estes novos canais. Quem são os usuários destas novas ferramentas? Qual a avaliação que eles fazem destes novos canais? Qual é a opinião deles sobre as possibilidades de participação eletrônica? O principal aspecto teórico abordado nesta dissertação é a seguinte discussão: a internet replica formas de participação tradicionais ou é realmente capaz de fazer com que mais cidadãos, incluindo aqueles que estão alheios e desinteressados, participem? Essas questões foram direcionadas ao Portal da Câmara dos Deputados do Brasil, que, ao longo dos últimos anos, soube adaptar-se e promover um espaço de amplo acesso a informações legislativas, com capacidade de contato e interação entre o cidadão e o seu representante e é considerado, atualmente, o melhor portal legislativo da América do Sul. A dissertação utilizou duas metodologias distintas. A primeira consistiu em analisar as estatísticas de acesso ao Portal, identificando assim os padrões de acesso: os sites de referência e os caminhos de busca através dos quais se chega ao Portal. A segunda consistiu na condução de um Web Survey para coletar a opinião dos usuários. O questionário aplicado teve como objetivo coletar avaliações das ferramentas disponibilizadas pelo Portal, identificar o perfil dos usuários e compreender-lhes o comportamento político no mundo off-line. Um dos principais achados é o de que a Democracia Eletrônica desenvolvida pelo Portal da Câmara dos Deputados tem servido mais aos profissionais da política que ao cidadão comum. Mas, mesmo assim, o cidadão comum, interessado em buscar participação, contato e interação com os atores políticos, está procurando essas ferramentas on-line. Palavras chaves: Democracia Eletrônica, Câmara dos Deputados, pesquisa on-line, estatísticas de acesso.

Search adaptations and the challenges of the web

Search has become a hot topic in Internet computing, with rival search engines battling to become the de facto Web portal, harnessing search algorithms to wade through information on a scale undreamed of by early information retrieval (IR) pioneers. This article examines how search has matured from its roots in specialized IR systems to become a key foundation of the Web. The authors describe new challenges posed by the Web's scale, and show how search is changing the nature of the Web as much as the Web has changed the nature of search

Fuzzy-neuro web-based multilingual knowledge management

This paper presents new methodology towards the automatic development of multilingual Web portal for multilingual knowledge discovery and management. It aims to provide an efficient and effective framework for selecting and organizing knowledge from voluminous linguistically diverse Web contents. To achieve this, a concept-based approach that incorporates text mining and Web content mining using neural network and fuzzy techniques is proposed. First, a concept-based taxonomy of themes, which will act as the hierarchical backbone of the Web portal, is automatically generated. Second, a concept-based multilingual Web crawler is developed to intelligently harvest relevant multilingual documents from the Web. Finally, a concept-based multilingual text categorization technique is proposed to organize multilingual documents by concepts. As such, correlated multilingual Web documents can be gathered/filtered/organised/ based on their semantic content to facilitate high-performance multilingual information access.

Ampliación de un portal Wordpress para el diseño de cursos basados en la metodología PBL

La metodología PBL propone el aprendizaje basado en problemas. A grandes rasgos sugiere que el estudiante sea el protagonista de su propio aprendizaje mediante el desarrollo de proyectos. Con esa idea, el grupo de innovación educativa DMAE-DIA (Desarrollo de nuevas Metodologías de Aprendizaje/Evaluación del Departamento de Informática Aplicada), comenzó la construcción de un portal web para mostrar los principios de dicha metodología, que permitiese a los usuarios del mismo conocerla y aprender a utilizarla en un entorno colaborativo. El objetivo de este trabajo es ampliar este portal para que los usuarios sean capaces de crear, eliminar y mantener sus propios proyectos para posteriormente utilizarlos como base para su práctica docente. El trabajo se ha planteado siguiendo el paradigma de la orientación a objetos, mediante la metodología UML y siguiendo el ciclo de vida del software y se ha implementado utilizando como base el CMS Wordpress y desarrollando con los lenguajes que más adelante se especificarán. Wordpress por su parte es un sistema de gestión de contenidos dotado de gran potencia que permite, de una manera muy sencilla, construir entornos web con el mínimo esfuerzo. ABSTRACT The PBL methodology proposed problem-based learning. Roughly suggests that the student is the protagonist of their own learning by developing projects. With that, the group of educational innovation DMAE-DIA (Development of new Learning/Assessment methodologies, Department of Applied Computing) began building a web portal to show the principles of this methodology, which would allow users to know and learn to use it in a collaborative environment. The aim of this work is to extend this website so that users are able to create, delete and maintain their own projects for later use as the basis for their teaching practice. The work has been raised following the paradigm of object orientation, by following the UML methodology and software life cycle and has been implemented using as a basis the CMS Wordpress and developed with the languages that will be specified later. Meanwhile Wordpress is a content management system endowed with great power that allows,in a very simple way to build web environments with minimal effort.
