A public-professional web-bridge for vaccines and vaccination: User concerns about vaccine safety

Vacunas.org (http://www.vacunas.org), a website founded by the Spanish Association of Vaccinology offers a personalized service called Ask the Expert, which answers any questions posed by the public or health professionals about vaccines and vaccination. The aim of this study was to analyze the factors associated with questions on vaccination safety and determine the characteristics of questioners and the type of question asked during the period 2008–2010. A total of 1341 questions were finally included in the analysis. Of those, 30% were related to vaccine safety. Questions about pregnant women had 5.01 higher odds of asking about safety (95% CI 2.82–8.93) than people not belonging to any risk group. Older questioners (>50 years) were less likely to ask about vaccine safety compared to younger questioners (OR: 0.44, 95% CI 0.25–0.76). Questions made after vaccination or related to influenza (including H1N1) or travel vaccines were also associated with a higher likelihood of asking about vaccine safety. These results identify risk groups (pregnant women), population groups (older people) and some vaccines (travel and influenza vaccines, including H1N1) where greater efforts to provide improved, more-tailored vaccine information in general and on the Internet are required.

Análisis de software de analítica web para medir uso de recursos y servicios electrónicos de bibliotecas universitarias

Las bibliotecas universitarias recopilan, de manera rutinaria estadísticas sobre el uso de sus colecciones impresas y de la actividad in situ. Paralelamente y de manera sostenida, han ido incorporando recursos y servicios electrónicos, lo que ha motivado la elaboración de normas internacionales que definen indicadores que permiten medir su uso, no obstante contar con un software estándar es aún un asunto pendiente. Por otro lado, para medir la actividad de un sitio web existen varios programas gratuitos y de código abierto. Este trabajo tiene como objetivo determinar si los softwares de analítica web gratuitos para sitios web AWStats, Google Analytics y Piwik, pueden utilizarse para evaluar el uso de recursos y servicios electrónicos, conforme a los indicadores propuestos por las normas ANSI/NISO Z39.7-2013, ISO 2789:2003, ISO 20983:2003, BS ISO 11620:2008, EMIS, Counter e ICOLC. Para tales efectos, fueron utilizados para realizar el análisis de esta investigación sitio web y el catálogo en línea de la Biblioteca Florentino Ameghino, Biblioteca Central de la Facultad de Ciencias Naturales y Museo de la Universidad Nacional de la Plata, Argentina. Los resultados reflejan las características de los indicadores, el software y el caso de estudio. Estas características son abordadas en las conclusiones con el fin de darle contexto y perspectiva a la respuesta de la pregunta de si es viable medir el uso de recursos y servicios electrónicos de una biblioteca universitaria por medio de programas estadísticos para sitios web

Web-based screening and brief intervention for hazardous drinking: a double-blind randomized controlled trial

Background Strong evidence exists for the efficacy of screening and brief intervention for reducing hazardous drinking. However, problems have been highlighted with respect to its implementation in health-care systems, not least of which is a reluctance of some doctors to discuss alcohol proactively with their patients. Aims To determine the efficacy of a novel web-based screening and brief intervention (e-SBI) to reduce hazardous drinking. Design A double-blind randomized controlled trial. Setting A university student health service. Participants A total of 16 7 students (17-26 years) were recruited in the reception area and completed a 3-minute web-based screen including the Alcohol Use Disorder Identifiation Test (AUDIT) questionnaire. Of these, 112 tested positive, and 104 (52 females) who consented to follow-up were included in the trial. Measurements Drinking frequency, typical occasion quantity, total volume, heavy episode frequency (females > 80 g ethanol, males > 120 g ethanol), number of personal problems, an academic problems score. Intervention Participants were randomized to 10-15 minutes of web-based assessment and personalized feedback on their drinking (intervention, n = 5 1) or to a leaflet-only control group (n = 5 3). Findings Mean baseline AUDIT scores for control and intervention groups were 16.6 (SD = 6.0) and 16.6 (SD = 5.7). At 6 weeks, participants receiving e-SBI reported significantly lower total consumption (geometric mean ratio = 0.74; 9 5 % confidence interval: 0.56-0.96), lower heavy episode frequency (0.63; 0.42-0.92) and fewer personal problems (0.70; 0.54-0.91). At 6 months personal problems remained lower (0.76; 0.60-0.97), although consumption did not differ significantly. At 6 months, academic problems were lower in the intervention group relative to controls (0.72; 0.51-1.02). Conclusions e-SBI reduced hazardous drinking among university students, to an extent similar to that found for practitioner-delivered brief interventions in the general population. e-SBI offers promise as a strategy to reduce alcohol-related harm in a way that is non-intrusive, appealing to the target group, and capable of being incorporated into primary care. Research is required to replicate the findings, to determine the duration of intervention effects, and to investigate the mechanisms by which the intervention operates.

Towards more personalized web: Extraction and integration of dynamic content from the Web

Information and content integration are believed to be a possible solution to the problem of information overload in the Internet. The article is an overview of a simple solution for integration of information and content on the Web. Previous approaches to content extraction and integration are discussed, followed by introduction of a novel technology to deal with the problems, based on XML processing. The article includes lessons learned from solving issues of changing webpage layout, incompatibility with HTML standards and multiplicity of the results returned. The method adopting relative XPath queries over DOM tree proves to be more robust than previous approaches to Web information integration. Furthermore, the prototype implementation demonstrates the simplicity that enables non-professional users to easily adopt this approach in their day-to-day information management routines.

Web wrapper validation

Web wrapper extracts data from HTML document. The accuracy and quality of the information extracted by web wrapper relies on the structure of the HTML document. If an HTML document is changed, the web wrapper may or may not function correctly. This paper presents an Adjacency-Weight method to be used in the web wrapper extraction process or in a wrapper self-maintenance mechanism to validate web wrappers. The algorithm and data structures are illustrated by some intuitive examples.

UncertWeb processing service:making models easer to access on the web

Models are central tools for modern scientists and decision makers, and there are many existing frameworks to support their creation, execution and composition. Many frameworks are based on proprietary interfaces, and do not lend themselves to the integration of models from diverse disciplines. Web based systems, or systems based on web services, such as Taverna and Kepler, allow composition of models based on standard web service technologies. At the same time the Open Geospatial Consortium has been developing their own service stack, which includes the Web Processing Service, designed to facilitate the executing of geospatial processing - including complex environmental models. The current Open Geospatial Consortium service stack employs Extensible Markup Language as a default data exchange standard, and widely-used encodings such as JavaScript Object Notation can often only be used when incorporated with Extensible Markup Language. Similarly, no successful engagement of the Web Processing Service standard with the well-supported technologies of Simple Object Access Protocol and Web Services Description Language has been seen. In this paper we propose a pure Simple Object Access Protocol/Web Services Description Language processing service which addresses some of the issues with the Web Processing Service specication and brings us closer to achieving a degree of interoperability between geospatial models, and thus realising the vision of a useful 'model web'.
