Abstract
Virtual reality (VR) potential to isolate users from the real world while producing a rich virtual environment where users act similarly to how they would, in reality, is still being investigated in several fields. In this work, we investigated the effects of product contextualisation and gender under an immersive VR application where users can explore in-depth a commercial product with a hands-on experience. An experimental between-subjects study was performed with 38 participants between 18 and 28 years. The product tested consisted of a double-door refrigerator equipped with a touchscreen. Two independent variables were studied: Context (the refrigerator was filled with food products and placed in a kitchen), Neutral Context (empty refrigerator displayed in an empty white room), and Gender (Female and Male). As for the dependent variables, we considered how clarified users felt about the product functionalities, its size, the extent users remember details and characteristics of the refrigerator, and the user's subjective workload. The evidence shows that contextualisation and gender have no impact on any dependent variables. Therefore, we concluded that presenting a product in its context does not benefit significantly benefit it. Thus, opting for a neutral context would be preferable to save computational costs and human resources necessary to build and run the higher complexity environments required to contextualise the product.

O processo de revisão sistemática de literatura em investigação continua a apresentar-se como um processo com um elevado custo de recursos humanos e de tempo. Com vista em otimizar este processo pretende-se estudar a performance da ferramenta de pesquisa Cognitive Search da Microsoft que contem funcionalidades de inteligência artificial (IA). Neste trabalho foi implementada uma solução de pesquisa, i.e., parametrização do serviço de pesquisa, que produz uma classificação de relevância dos artigos científicos. Uma análise qualitativa aos artigos científicos foi efetuada para analisar a performance da solução de pesquisa e habilidades de inteligência artificial da ferramenta. O tema da revisão sistemática é “how is artificial intelligence (AI) being used in Higher Education (HE) today, involving tree dimensions: learning with AI, learning about AI and learning for AI”.;The systematic review process of research literature continues to be a very time and human resource expensive process. With the objective of optimizing this process we intend to study the performance of Microsoft Cognitive Search service which contains artificial intelligence capabilities. In this work the search service tool was configured and parameterized (search solution) to produce a classification ranking of the research articles. These were manually analysed to infer on the performance of the search solution. The topic of the systematic review is “how is artificial intelligence (AI) being used in Higher Education (HE) today, involving tree dimensions: learning with AI, learning about AI and learning for AI”.

Abstract
This chapter aims to contribute to a better understanding of the role of websites in business internationalization by exploring how website overall objectives and their coherence with website strategies support website internationalization effectiveness. It provides empirical evidence on the experiences of Portuguese companies shared by 20 managers of large companies and SMEs of various activity sectors. Results show the importance of a clear website strategy (e.g., clear objectives and coherent tactics) for an effective role in internationalization. Findings also confirm that, while many managers are skeptic about the effectiveness of websites as an internationalization touchpoint, namely due to sector characteristics (e.g., type of customers, type of products/services), the website is perceived as an essential tool for reaching, attracting, and involving international customers, supporting other communication instruments such as participating in international fairs and sales force.

Abstract
Social media is one of the greatest achievements of technological evolution. Nowadays, we have the world in our hands, just a click away. But if, on one hand, the community saw social media as a progressive tool, strict governments saw them as a threat to their regime. China was one of the countries that imposed a highly repressive strategy which blocked foreign content, therefore, websites like Google, YouTube and Facebook are blocked, and Chinese netizens can only access government approved websites. Surrounded by this Firewall, the Chinese are kept complacent towards the government's decisions and are held back from speaking against it. From this situation, we began wondering the extent of our opinion permeability towards social networks in the West. We set a parallelism between two different situations but, in a way, complementary. Is our political opinion shaped by the content we see on social networks? Is there a strategy being applied to purposefully guide our opinion? This was the focal point of our survey which was applied to a Portuguese sample. A survey was created on Google Forms where both individuals' perspectives were assessed. The research sample was a convenience sample, which included 160 answers. Most participants (66%) said they considered that social networks serve as a mechanism for disseminating political ideologies. Moreover, 49.38% believe that social networks can have an impact on real-life decisions regarding the political sphere. Through a careful analysis of the data, we concluded that people seem to be aware of the magnitude that social media has had in politics lately, and they are, in general, responsible commentators who, most often, look for a second source of information. Notably, we have become somewhat intolerable to the opinions of others because we have closed ourselves in our own communities, in the content that our algorithm chooses for us and in a way, we are, as the Chinese, restricted to a digital bubble of information alongside with others who share the same political beliefs.
