To date, the knowledge and use of ICT (Information and Communication Technologies) has become an almost essential requirement when someone wants to find employment in our society. For this reason, this study aims to analyze the importance that students of the Faculty of Business Studies and Tourism of the University of Huelva (Spain) give to the acquisition of ICT skills for their future professional performance and the domain they have over them (achieved throughout their years of learning). This research is developed through a questionnaire completed by 90 students of the Faculty and concludes that in general they give these ICT skills the importance that they deserve and that their domain goes in parallel (except for some skills that show formative need), even being able to observe that in the majority of cases the dominion of these skills is tied to the importance that they give them.

Many factors can influence decision-making, and if you wish to know which are the most influential factors in a decision, they must be classified by their degrees of influence. This study seeks to determine the most influential factors in the decision of hotels to accept and implement the Internet of Things in their services through a literary review and a causal study carried out on experts in technology and hotels. The methodology involves the use of fuzzy cognitive maps and the FCMappers tool. The results obtained show that the following factors are among the most influential (in order of relevance): the perceived reliability of the technology, the relative advantage it gives, the level of top management support, compatibility, customer pressure, information systems provider support, security, business partner pressure, characteristics of the leader or manager, government pressure or incentives, pressure from competitors, technological organizational readiness, complexity, size of the company, and the perceived cost.

The acquisition of skills in ICT (Information and Communication Technologies) has a relevant role in the training programs of educational institutions, since these skills are among the most demanded when companies decide to look for workers. For this reason, this study aims to analyze the training in ICT skills that the students of the Faculty of Business Sciences and Tourism of the University of Huelva (Spain) possess according to their professors and the importance that these professors give to their acquisition for the future professional performance of their students, and observe if these two variables differ from the opinion of the students, to know if corrective measures should be taken in the training programs when transmitting said skills. This research is carried out through a questionnaire carried out to 46 professors of said Faculty and concludes that, in general, the study plans have been able to promote the learning of these ICT skills and to relativize the acquisition of these for the future job performance of their students.

Many of the tools used for virtual teaching during the pandemic had not been used previously, but they could continue to be used when traditional teaching returns. For this reason, this study focused on locating the key motivational factors for the possible continuation of the use of one of these tools, videoconferencing, to carry out tutorials in Spanish universities as a complement to face-to-face tutorials. For this, a literary review was conducted to obtain a list of motivational factors that may influence teachers to continuing using it, and a causal study was performed with university professors (through fuzzy cognitive maps) to identify the causal relationships among these factors and classify them by their relevance in making a decision. The most influential factors are intention, attitude and perceived compatibility with how tutorials are given, and the negative factors include quality management and trust.
