Abstract
The challenge of creating user experiences involves a panoply of multidisciplinary competences in terms of knowing tools, processes and the business itself. This study intends to identify and synthesize the main approaches and principles adopted by web design and e-business companies to create immersive user experiences. In order to achieve this objective, the authors conducted six semistructured interviews with web design and e-business companies. They highlight that companies adopt specific-device design, responsive design and adaptive design approaches. Companies considered fundamental to attend technology life-cycle, heterogeneity of technologies and devices, identification of customer needs, relevance of test phase, scalability of applications, and accessibility and usability issues. Additionally, the customer experience testing is considered a key element to measure user experiences and companies expect that business and technological dimensions will be two key factors with future impact in their business.

Abstract
Responsive design allows software developers to build a Web page that can dynamically adapt to the size of the devices. This development philosophy enables the rendering of Web pages in a fast and optimized way, ensuring a good user experience on mobile devices, tablet and desktop. In the scope of this study, we intend to explore the main advantages and limitations associated with responsive Web design. We adopted a quantitative approach based on a questionnaire filled by 181 professionals in the industry that allowed us to identify the reasons that lead software developers to the adoption of the responsive design and also address the limitations felt by them. The results obtained indicate that offering a good user experience and increasing accessibility stands out as being the most important advantages. On the other hand, the main limitations include the compatibility with older Web browsers, the higher loading time and the difficulties in optimizing user experience. Finally, it was found that the perception of the advantages and limitations of responsive design is distinct for professionals with more professional experience in the field and for freelancer developers. © 2017, Fernando Almeida and José Monteiro.

Abstract
Abstract   The teaching of entrepreneurship is currently a fundamental pillar in the construction of social responsibility with strong impact on the future economic development of society. The use of serious games in the entrepreneurship field is a way of encouraging students' motivation to become entrepreneurs and develop their skills in the field. In this paper, we describe the experience of using a serious game in the entrepreneurship field in the context of the classroom. For that, we adopt a quantitative research technique based on a survey research to measure the different characteristics experienced by higher education students when using serious games in the classroom to learn entrepreneurship. The students have multidisciplinary competences, coming from courses with strong emphasis in the area of management and technology. The use of the serious game allowed students to develop skills mainly in terms of innovation, leadership, strategic thinking, problem solving, business launch and risk management. On the other side, there were no significant benefits in terms of accounting skills, compliance with regulations, interpersonal, communication, and self-control and discipline. Keywords: entrepreneurship, serious games, higher education, game based learning, gamification.

Abstract
Web 4.0 is a new evolution of the Web paradigm based on multiple models, technologies and social relationships. The concept of Web 4.0 is not totally clear and unanimous in literature, because it is composed by several dimensions. In this sense, this study uses a systematic review approach to clarify the concept of Web 4.0 and explore its various dimensions, analyzing if they have elements in common. The findings indicate that the number of studies published from 2009 to 2017 on this field significantly increased, having reached a peak in 2014. Furthermore, we identified five dimensions associated with the Web 4.0 paradigm, in which the terms “pervasive computing” and “ubiquitous computing” are the most widely used in the literature. On the other side, terms such as “Web 4.0”, “symbiotic Web” and “Web social computing” are not often used.
