Abstract
Information technology has become one of the core elements of electronic government (e-Government) and should figure prominently in future governance. E-Government services, through electronic means, should provide a more cost-effective and convenient way for citizens to interact with government, however their adoption is still far from a satisfactory level. The study herein has examined research on the adoption of e-Government services. Using data obtained from previous research, this article identifies the variables that contribute to the adoption of e-Government by citizens and the model created is presented. Overall, this study concludes that e-Government has been adopted by many governments, but it is still at an early stage, and there are still barriers to its more widespread adoption in society.

Publication
Electronic Commerce Research and Applications

Abstract
The incredible numbers associated with social network sites makes technology a very attractive element in the eyes of organizations. Despite this, the existing scholarly literature does not demonstrate sufficient knowledge on how firms should adopt and use these technologies. With this lack in mind, a study was conducted aiming to understand what might be the determinants with the most influence on the SNS adoption process at firm level. the study was performed making use of a mixed methodology approach. In order to achieve an initial list of variables that might have a significant level of relative importance (RI) to the adoption of SNS, a Delphi study was designed and executed through the inclusion of 25 experts in the IT/IS area. From the Delphi results, a proposal for an adoption model that characterized the adoption of SNS at firm level was designed and validated through an empirical study. This empirical approach revealed that the proposed model explained 65% of variation in SNS adoption at firm level. The active involvement of top management, the alignment of the SNS plan with the firm's business plan, the existence of competitive pressures, and the use of SNS for gaining competitive advantages are the determinants with the most influence on technology adoption by firms.

Web accessibility - From the evaluation and analysis to the implementation - The anoGov/PEPPOL case

Authors

Publication
Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)

Abstract
The XXI Century society has developed a drive for Information and the Web, as one of the extremely important technologies of our times, represents the main channel to access it. As a result of this, one can perceive that the Web, and the inherent websites, must be accessible to all, in order to maintain the imperative social equality. Despite the legal requirements to the Portuguese Web content accessibility levels, in effect since 1999, the existent studies that focused on assessing those same levels of accessibility reported that the Portuguese websites, in their majority, were not compliant with the existent standards. In mid-2007 we started, within our research group and in partnership with both UMIC - Knowledge Society Agency and APDSI - Association for the Promotion and Development of the Information Society, a Web accessibility barometer. The goal of this barometer has been assessing the accessibility levels of the Portuguese websites, creating recommendations - for both the organizations and the civil society - towards the improvement of the referred websites, and publicly presenting the achieved results. One of the Portuguese enterprises that is adopting the accessibility standards into its public procurement platform anoGov is ANO. This company established a research project alongside UTAD University in order to achieve technical know-how and good practices that allowed them to develop accessible and usable Web content. © 2013 Springer-Verlag Berlin Heidelberg.

Advances in Intelligent Systems and Computing

Abstract
With the rapid growth in the use of digital platforms for the dissemination and expansion of a company’s business reach, it is vitally important that startup firms are firmly aware of the options when deciding whether to adopt a particular technology because they often have low resource availability, which reduces their margin for error. In order to help these companies to adopt Digital Marketing in a more secure way by knowing the most relevant factors that they can find as concerns the adoption of technologies, this study will analyze the factors that influence the adoption of technology, identifying them initially through the systematic literature review of similar scientific works. © Springer International Publishing AG 2018.

PROCEEDINGS OF THE 2014 9TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI 2014)

Abstract
In general, managers have different opinions from those advocated by CIOs in relation to Information Systems, especially with regard to their importance and value to the business as well as in terms of investment needs. Here, we discuss and study new approaches to methods and tools for assessing the relative importance of each information system for business, focusing on the insurance companies. We applied the CRUDi Framework that introduces new key indicators for better decision support and to identify investment priorities, presenting results regarding the relative importance of each process to support the business strategy. The main contributions of this work are the CRUDi Framework Case Study of application in an insurance company, as a tool to improve alignment between business and IS strategies and the discussion of the achieved results.
