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.

Abstract
The evolution of technology, and mainly the evolution of the Internet, has improved the way business is done. Nowadays, most services are offered through a website or through an app, as it is much more convenient and suitable for the customer. This business transformation made it possible to get a faster and cheaper service, and companies had to adapt to the change, in order to fulfill customers’ requirements. In this context, this paper relates to this digital transformation, focusing on a case study about Netflix, a former DVD rental company and currently an online streaming leader. We aimed to understand Netflix’s behavior alongside this digital wave. Thus, we performed a survey, which had 74 answers, mainly from Portugal, but also from Spain, Belgium, Italy, Turkey, Georgia and Malaysia. Of the people who answered the survey, 90.1% were stream consumers, but only 59.1% had premium TV channels. From those 90.1%, 58.3% also said that they watched streams between two and four times per week, but the majority of premium TV channel subscribers (63.8%) replied that they watch TV less than twice in a week. We see a trend in which the traditional TV industry is in decline and streaming as a service has increased in popularity. Consumer habits are changing, and people are getting used to the digitalization era. Netflix is also confirmed in our survey as the market leader of the entertainment distribution business, as stated in the literature, and the biggest strength of this platform is its content. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
Social media platforms have been increasingly used by companies, over the past few years, in order to make their recruitment and selection process more efficient. The aim is to gather more data about the applicants’ competences and personality traits, assuring that they are hiring the right candidates. Nevertheless, this method may be controversial since it can lead to different legal and ethical issues such as discrimination and invasion of privacy. Additionally, some problems may arise regarding the validity and fairness of the information found in such platforms. As Facebook is the most frequently used social platform among students and recently employed workers, we chose it as the main focus of our survey (which had 212 answers), in order to understand the applicants’ point of view about this subject. The main conclusions were that the majority of the respondents affirmed being aware of this practice, despite not agreeing with it; and, also, they do not believe that this is a good tool to evaluate their potential. Finally, our participants’ answers also led us to conclude that there could be contradictions regarding their judgement about the accessing of personal information by firms on Facebook. 76,9% of our respondents affirmed that they usually assess the profile of people who send them friend requests. Our respondents consider the use of Facebook during the selection process as being unethical, even though they assess others’ profiles and search for information themselves. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.
