Abstract
The impact of the digital revolution has influenced society significantly in many ways, including with Artificial Intelligence (AI). The advantages and disadvantages of AI and what can be and should be done in order to influence that in a positive way are discussed. The study is based on interviews (ten) and survey answers (from 100 respondents). The survey results show that there is a general concern about the impact of AI in the future (the negative impact on work and related to a general loss of control). Furthermore, more than 50% of the answers lead to the thought that "Humans will learn to use the power of computers to improve their own skills and be ahead of AI". As concerns the interviews, it was interesting to realize that practical courses, such as students studying engineering, were the ones who were afraid of AI instead of the social ones. This may be because the engineering students are the ones who know more about AI so they better realize the possible implications of AI on their future jobs. Another possible reason is that non-engineering students believe that human sensibility needed in their fields of study is more difficult to reproduce by AI machines than technical skills present in other fields of study/jobs.

Abstract
This article was written to study and understand how social networks have changed the way we perceive and create relationships. The exponential increase of social media (SM) has become not only convenient, but also a common habit. It has changed people’s habits and brought a new way of being since the technology era arrived. Although there are several advantages in using these social networks, the uncontrolled use and abuse can be alarming, thus the importance of this research. There are plenty of papers related to the impact of social media on adolescent behaviour and on young people’s academic performance. However, this paper aims to examine the facts and provides a comparison of the effect of social media use between different age sectors: adolescents (between 10 and 17 years old), young adults (18–30), adults (31–45), older adults (46–65) and seniors (+66). In order to explore this issue, an online survey was developed. Using a sample of 358 participants, social media use was analysed by age sectors, focusing on the dependence, habits, the reasons/motivations for people to have these accounts, and how different generations perceive the future of social media. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020.

Abstract
Current European Union legislation demands that websites that use web cookies to extract information about the personal preferences of Internet users request their permission to obtain such data. Widespread misinformation about web cookies threatens users’ feelings of security while leading also to a lack of privacy problems due to the need to accept cookies. However, not accepting cookies raises functionality issues on websites, and the value created by companies is not optimized. This article reviewed the existing literature and conducted a survey (with 102 valid responses) to understand Internet users’ behaviour in terms of fear of accepting cookies and the benefit generated by cookies to users. We conclude that the trade-off between security and performance of websites portrayed in the literature is illusory and is mainly due to the lack of information about cookies by users. We also conclude that there is a paradox: although most users feel insecure, they eventually accept cookies to simplify their online browsing. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020.

Abstract
We live in an age of constant technological evolution where we witness an increasing need for adaptation, in view of market challenges. These transformations create interactions between human beings and machines. This article is a case study based on qualitative and quantitative research, which approaches the implementation of a robotized system in a retail convenience shop, at a petrol station. The main objective was to focus on understanding the applicability of this type of system in a shop, as well as to ascertain its future in the short, medium and long term. Field research performed involved a personal interview with an executive at the Portuguese firm PRIO Energy – the Director of Research, Development and Innovation. The essence of the interview was to enquire about the robot experiment and to understand how innovation occurs, and where the ideas come from. Two other firm employees were also contacted for their testimonials on the project – the convenience store manager and the project innovation manager. Light was shed on which phases the innovation project went through. Finally, the authors has access to the results of a consumer survey involving 210 customers, who interacted with the robot station during its test phase. While not all feedback was good, namely some consumers are concerned that robots will be replacing humans in the workplace, leading to unemployment; the vast majority of the 210 survey respondents saw the experience as positive and one which they would repeat in the future. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020.

Abstract
At an estimated annual growth rate of 13.74%, the global health informatics market can reach $123 billion, by 2025, figures that exemplify the development trends of an ever-growing industry. The authors decided to collect data from the general public through an anonymous survey on the subject of health informatics. This survey was developed on Google Forms and later sent to multiple recipients by email and shared on social networks. A total of 165 people, aged 16 to 81 years old, participated in this survey. 98.8% of the respondents consider response time in health a determining factor. 97.6% of the survey participants consider that it is possible to make more accurate and viable clinical diagnoses using health informatics. Furthermore, according to our survey, people do not mind mortgaging their personal data (which is known from the outset for its incalculable value) because they know that, in return, they will benefit from better living conditions. Three experts were also interviewed and according to one of them, one of the biggest challenges in health informatics is “understanding and detecting diseases long before they happen”. This interviewee also stressed the importance of artificial intelligence “in helping people to improve their health through indicators that alert and recommend certain habits and influence the improvement of people’s quality of life”. Finally, the emphasis needs to be on eliminating health costs and facilitating life for people with chronic diseases. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020.

Abstract
Portugal is a country with a large coastal extension and a fishing and sea tradition which place it on the top of fresh, salty and deep-frozen fish consumption in the European Union. The incapacity by consumers to evaluate the degree of freshness and quality of fish for consumption may cause health problems, such as food poisoning, hence the preference of consumers for deep-frozen products instead of healthier fish that is sold fresh. In this project we intend to contribute to an improvement in the evaluation by the final consumer of the quality of fresh fish sold to them through creating a reference table of fish degradation (at this experimental stage for mackerel and sardine) and the development of a mobile application allowing, in a near future, for users to determine the rate of freshness of fish they wish to acquire. The reference table creation is based on the degradation/dehydration of the fish’s eye as well as a respective coloration (opaqueness), which changes according to the time since the fish was caught. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020.
