Abstract
This work results from an exhaustive characterization of the practices of E-commerce through the use of a questionnaire to small and medium enterprises of Tras-os-Montes and Alto Douro in Portugal, seeking to identify and promote the use of this technology in order to obtain competitive advantages.

Abstract
The research team measured the enterprise web accessibility levels of the Forbes 250 largest enterprises using the fully automatic accessibility evaluation tool Sortsite, and presented the compliance of the evaluated websites to WCAG 1.0, WCAG 2.0 and Section 508 accessibility levels. Given the recent attention to organizational leaders having ethical duties towards their dedicated employees, we propose that 'societal citizenship behaviour' concerns ethical duties of organizational leaders towards society in general and in particular to those who have less means to assert their needs. In effect, we found enterprise website accessibility levels to be in need of significant improvement. An interpretation of a positive path forward to better enterprise website accessibility levels is put forth based on a focus-group interaction and using BNML-a novel Business Narrative Modelling Language.

Abstract
Currently, Virtual Worlds technology is used for educational purposes in a cross-disciplinary way. However, particularly in formal learning institutions, its widespread adoption is far from being a reality due a broad range of technological challenges. This paper addresses identity federation systems as possible solutions to some of the interoperability, security and user management problems. Our major goal is to present what systems, architectures and standards are standing out, how the research area is moving toward identity federation, and why educational institutions need to address it. We consider identity, privacy, security-assurance, and interoperability as main concerns within our analysis, in order to interconnect digital identities with physical identities, and create a unique federated identity system that can act independently from the service in use. Thus, VWs technologies will be able to scale and evolve independently without compromising user's identity.

Abstract
This paper describes a proposal to develop a Tourism Recommendation System based in Users and Points-of-Interest (POI) functionality/accessibility levels. The focus is to evaluate if user’s physical and psychological functionality levels can perform an important role in recommendation results accuracy. This work also aims to show the importance of POI classification (accessibility levels are related with each POI ability to receive tourists with certain levels of physical and psychological issues), through the definition of a different model regarding their accessibility and other characteristics. © Springer International Publishing AG 2018.

Abstract
Organizations are increasingly concerned with process optimization, thus aiming on gaining competitive advantages in the market. Inherent to any business, company or institution there is a constant document creation, manipulation and treatment flow. In many cases a real bureaucratic chaos. These processes involve great efforts in terms of human resources and are highly susceptible to errors. Sousacamp is a group of companies in the agrifood area that are geographically distributed throughout the Iberian Peninsula. Given that the group companies buy and sell from each other, the paper volume inherent to documenting these transactions is significantly high. This paper presents a documental integration strategy supported on the development of an application using ASP, .NET and C#

Abstract
The academy can and should have a major role in the promotion of software accessibility. To try to clarify a number of empirical arguments and certainties regarding the usage of accessible, but not assistive, software, the answers to a survey given to 15 blind or low vision people are depicted. To demonstrate how under addressed this topic is by the academy an experiment was made, and its results are portrayed. The novel contribution that this paper offers is the relation between relevant accessibility documentation to its appropriate type of user interface, which is intended to encourage the introduction of the topic of software accessibility implementation. Also, a proposal for a first slide, regarding accessibility implementation in software meant to be shown to software engineering students, who should produce accessible software in their future, is presented. As a conclusion, some insights are given and new possible research avenues are depicted.
