Abstract
The current technological and social Era in which our society lives, provides for the necessary background in order for Social Networks Sites (SNS) to be considered an essential and very relevant tool not only for individual social interaction, but also for firms to perform business activities. By analyzing the existent literature on the SNS adoption at firm level, the authors perceived the existence of a knowledge gap on this topic, thus creating the need for a SNS related literature review. In this paper, we present a systematic literature review on the SNS topic, mainly focusing the efforts towards the adoption of this technology at firm level. Some final considerations on future research are also presented in the final section of the article.

The current paper describes an accessibility evaluation that aimed to test the Portuguese enterprises websites. Has the presented results state, the evaluated websites accessibility levels are significantly bad, but the majority of the detected errors are not very complex from a technological point-of-view.

Abstract
The need and benefits of digital accessibility are evident and, with the current ubiquitous trends, the profits are hugely potentiated. However, the fast evolution is instigating some issues in this area's accessibility. To understand the conceivable impact of these issues' tenacity in society, general accessibility features are explained as a reasonable application for all parties. Nevertheless, the potential of ubiquitous computation in order to promote social integration of citizens with impairments is focused and elucidated. The benefits of applying so much effort on accessibility as well as on usability is asserted and related to universal design. Hence, in order to promote a more universal applications development, the mobile operating systems available in the market, which are more plausible to be chosen and used by people with impairments, are scrutinized and shown from a standpoint of a developer that has accessibility and usability concerns. The paper leads to the conclusions that ubiquitous computation may have power to nullify impairments but, to be assistive, several issues regarding the devices and the operating system that runs on them have to be taken in mind and considered.

Abstract
The alignment of information systems with the business goals of an organisation, although a topic of great importance, is not always properly valued or taken into consideration. In general, managers have different opinions to chief information officers (CIOs) in relation to IS, especially with regard to their importance and value to the business and also 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 to business, focusing on the financial sector including banks and insurance companies. We suggest the introduction of new key indicators for better decision support and to identify investment priorities, and present results regarding the relative importance of each process to support the business strategy. The primary goal for the inherent research project is to analyse the main problems and difficulties encountered by IS and IT managers, featuring different players and how they relate. The main contributions of this work are the CRUDi framework as a tool to improve alignment between business and IS strategies and the CRUDi survey and its results qualifying the financial sector's opinion regarding the relative importance of processes and investments.

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.
