Purpose – The purpose of this research is to present a brief overview of some proposals for portal quality models. In addition, a comparative study is carried out to determine the similarities and differences of these models. Design/methodology/approach – In order to compare the different portal quality models, their main characteristics were analysed as well as the different dimensions proposed in each model. Findings – As a result, several similarities and differences have been established among the portal quality models. For example, the dimensions present in all the models are navigation, representation, personalization and intrinsic data quality. This means that, as expected, it was found that researchers pay special attention to visual aspects. Practical implications – The comparison attempts to determine which aspects are important for the quality of a web portal, and also to clarify which proposal is the most broadly relevant. The paper also identifies, where necessary, what features must be added in order to ensure that all aspects related to web portal quality are considered. Originality/value – This work tries to identify a portal quality model that can be used to gauge portal quality levels. The model could also be used where there is a low quality level for a particular dimension, giving some guidelines for improving the weaker aspects.

    • "It is important to note that while web usage statistics provide a quantitative indication of knowledge access, monitoring usage patterns does not infer evidence-informed decision making in public health. Performance evaluation models that help to measure how portals are assisting in knowledge management activity [37,38] are still in development and no one model has been shown to be superior. Dobbin et al. [20] found that organisations with a high research culture responded best to the use of a KEP in combination with tailored and targeted messages, whereas organisations with a low research culture responded best to a knowledge broker in terms of facilitating the implementation of public health policies and programs.

    ABSTRACT: Background Knowledge exchange portals are emerging as web tools that can help facilitate knowledge management in public health. We conducted a review to better understand the nature of these portals and their contribution to knowledge management in public health, with the aim of informing future development of portals in this field. Methods A systematic literature search was conducted of the peer-reviewed and grey literature to identify articles that described the design, development or evaluation of Knowledge Exchange Portals KEPs in the public health field. The content of the articles was analysed, interpreted and synthesised in light of the objectives of the review. Results The systematic search yielded 2223 articles, of which fifteen were deemed eligible for review, including eight case studies, six evaluation studies and one commentary article. Knowledge exchange portals mainly included design features to support knowledge access and creation, but formative evaluation studies examining user needs suggested collaborative features supporting knowledge exchange would also be useful. Overall web usage statistics revealed increasing use of some of these portals over time; however difficulties remain in retaining users. There is some evidence to suggest that the use of a knowledge exchange portal in combination with tailored and targeted messaging can increase the use of evidence in policy and program decision making at the organisational level. Conclusions Knowledge exchange portals can be a platform for providing integrated access to relevant content and resources in one location, for sharing and distributing information and for bringing people together for knowledge exchange. However more performance evaluation studies are needed to determine how they can best support evidence-informed decision making in public health.

    • "Hasta ahora, el énfasis de la comunidad de Calidad del Software ha estado puesto en la valoración de la Calidad Interna y Externa de los productos software (véase [1] [2] [3] [6] [8] [10] [11], principalmente porque estas dos vistas están definidas de forma más precisa en la literatura, se pueden identificar más fácilmente y, por tanto, son más fáciles de evaluar. Esta relación entre la Calidad Externa y en Uso de los productos software parece estar basada en la presunción de que tener un producto con una alta calidad (externa) garantiza un producto con una alta Calidad en Uso.

    ABSTRACT: Proposals to improve the quality of software products have traditionally focused on improving the Internal or External Quality (regardless of the possible contexts of use) based on the idea that a good External Quality (within the meaning of ISO/IEC 9126) guarantees a good Quality in Use. This paper presents another way, moving the focus toward the Quality in Use as a significant/decisive element to design high quality software products for specific users or to select the product that better fulfills the client requirements. Our proposal is to analyze the relationships between External Quality and Quality in Use to determine the external quality subcharacteristics which are really significant to ensure the required quality level of a product in a specified context of use. The aim is to avoid unnecessary costs or irrelevant characteristics for the end user which unnecessarily raise the cost and effort of product development. We propose Bayesian Networks to model these relationships and provide a method to define them in a measurable way. As an example of using the proposed method we focused on the domain of software components to analyze their Quality in Use.

    • "A common extension of the service quality discussion is to consider the quality of e-services or online services (Zeithaml et al., 2000, 2002; Parasuraman et al., 2005). However, much of this literature is concentrated on the technical aspects of quality in e-services, such as website design and availability of information (Moraga et al., 2006). Furthermore, most of the studies adopt an e-commerce context. "

    ABSTRACT: Virtual communities are an increasingly popular way to conduct business over the Internet. However, from the service provider's point of view they pose special challenges. In particular, unless the provider itself engages in content or service provision, the service relies entirely on its members for provision of services. The members should thus be seen as resources for service provision. This type of networked service production system implies challenges in terms of service quality management and, subsequently, value creation for community members. This paper explores these issues by revisiting service marketing and service operations literature on service quality. Our analysis of the literature indicates that firms facilitating virtual communities need to ensure the quality of their service by not only ensuring technical quality but also by nurturing the social aspects of the community that have an impact on the willingness of community members to provide service to each other.
