Abstract
LinkedIn is undoubtedly a market leader when it comes to social networks that are aimed for professional use, demonstrating over time that it is a highly valued instrument used by recruiters, as well as a successful way to complement/replace organic recruitment. One of the areas with the most current demand and specific requirements/skills is Information and Communication Technologies (ICT) and, as in all scientific fields, there is a huge focus on recruiting the best candidate in the shortest time possible. The key goals of this article are to understand the relevance of LinkedIn use by an ICT recruiter taking into account the specific requirements/skills often desired by companies, to perceive if ICT students and workers with an updated LinkedIn profile are contacted by recruiters, and comprehend if it is true to say that recruitment via a social network is faster and does not detract from the quality of the hired candidate, compared with organic recruitment. A survey was performed focusing on students and workers in the ICT field and two semi-structured interviews were conducted in a consulting firm as well as in a software house. The results obtained suggest that LinkedIn is an essential recruitment tool for the ICT companies/consulting firms, but it is important to emphasize that most companies combine organic recruitment with LinkedIn recruitment. In our study, 89% of the respondents with an updated LinkedIn account have already been contacted by recruiters, proving that LinkedIn can certainly increase the probability of being hired. © 2019, Springer Nature Switzerland AG.

Abstract
The purpose of this work was to collect information about how technology influences children nowadays, in Portugal, an intermediate technology country in the European Union. The methods used were interviews and questionnaires presented to children (a total of 38 children), parents (15 parents) and teachers (three teachers) in order to find out how they feel about today’s technological devices and how they think they can influence the society of the future, and whether they have a negative or positive impact or both. The methods selected were seen to be the best to obtain the desired answers, because public opinion is assuredly a good way to receive feedback about various contemporary products and phenomena. The conclusion was that every child in the sample owns digital devices and this influences them mostly in a positive way, in the opinion of their parents and teachers. Technology can also influence them in a negative way, but only if used so much that it becomes an addiction, affecting the child’s attention in school, as well as their daily activities. The motivation to do this research study was mainly that one of the authors has four children and can see the profound changes inflicted in them by technology versus older generations and thus an exploratory study into technological change brought on by devices, gadgets and social media was decided upon. © Springer Nature Switzerland AG 2019.

Abstract
Individuals currently spend a considerable part of their day-to-day lives interacting with computer or smartphone screens. This study seeks to contradict this and is based on participant observation during a trip from 16-28 August 2018, to Istanbul and to South Asia. We have found that the role of technology may be a medium which shows that we are similar in many ways, despite being separated by large distances and by language. Observation is essentially a tool to uncover meanings, which a visitor and researcher may see. In particular, in the Maldives, on Meedhoo island, we saw a superior form of living. Harmony was the main element we saw on the island, including between genders, which we saw as being equal, despite what is to be found written in the media about certain cultures and religions. Albeit, Istanbul, in Turkey, revealed a culture that still remains very different from the West.

Abstract
We hear more and more about autonomous vehicles, however, where are we heading with automation? Recently, we have heard about some crashes of autonomous vehicles, which have occurred during trials. Therefore, can this technology be trusted? Equally important, what kind of moral and ethical questions are behind the decisions that a vehicle like this must make? Who should be saved if someone must die, in a car accident? The elderly, or perhaps younger people? Executives or the homeless? People who follow traffic rules, or is that not relevant? This article will start by reviewing some of the ethical questions that have already been raised and results found within the public domain. Then the article proceeds by discussing our survey, administered in Portugal, with 111 answers. For situations which would seemingly lead to an obvious consensus and to a 100% agreement on the matter, we found this to not be the case, as our survey never achieved such polarized results. For example, even when confronted with saving pet animals or children, there was still a split in the choice made (albeit pending heavily towards saving the children). This goes to show how people are different and make different choices in life. Are we superior to animals and do we have a greater right to life than pets? Of course, this is debatable, according to differing values and cultures. Therefore, it follows that much debate should ensue as to how to program autonomous vehicles to behave - in case the loss of life (in whatever form) is at stake. Automation, as such, is thus leading us down ambiguous avenues where grey areas abound and we may simply not know what is best all of the time. Automation is thus making us work harder at being human beings and is bringing us to new levels of rationality - where emotions should also play a big part. The spontaneity and intuitiveness of human decision-making being taken out of the equation (when an accident occurs without automated cars that is how we think) makes many pre-meditated decisions uncertain and unpopular. Profoundly humane issues, which are often culture specific, are thus yet to be discussed.

Abstract
This article serves to show how things are changing when it comes to business and social networking. Nowadays, it is hard to find a business that does not have an account on any social network, and we can safely say that social media is a crucial aspect for any business enterprise - to sell their products, to be seen and, obviously, to make more money. We talk about the possibility to mix innovation, business strategy and social media. To complement this research, we focused our work on a Portuguese start-up - Strain - that intends to prove marketing is changing and that it actually welcomes the change, with social networks at the base of their business. They intend to use online influencers to promote the image of a brand, free of charge, and earn discounts on it. It is, indeed, a win-win situation, where each of the three parts (the company itself, clients and Strain) is a winner one way or the other. © 2019 AISTI.

Abstract
We have sought to understand the current state of the art on smart tourism and on smart cities. Furthermore, we have sought to understand community awareness and the will to embrace innovation, as they are decisive factors to acquire base knowledge and overcome barriers in (soon to be) overpopulated cities and for those who are looking for a limited time culture experience - known as tourists. We live in an age where technology is increasingly present in our lives and provides us solutions to societal problems. Problems such as traffic, infrastructure and natural resources management, or even increasing citizens’ participation in governance, bringing them closer to decision-making. The objective is to understand the current level of people’s knowledge about the impact that technologies have on the society in which we live and their perception of the usefulness in solving these same problems. Therefore, an anonymous questionnaire was carried out (176 valid answers were received), as well as a focus group with two experts on the Smart Cities subject. What future is brought by those who live and breathe technology? Are people willing to accept a paradigm shift?. © Springer Nature Switzerland AG 2019.
