Abstract
Entrepreneurship is currently one of the most fundamental economic activities in the 21st century. Entrepreneurship encourages young generations to generate their self-employment and develop key soft-skills that will be useful throughout their professional career. This study aims to present and explore a case study of a higher education institution that adopts FLIGBY as a serious game, which allows students to develop entrepreneurship skills in an immersive way and based on real challenges that can be found in business environments. The findings indicate that FLIGBY offers relevant potentials and new possibilities in the development of management, leadership, and entrepreneurship skills. Furthermore, the game allows the inclusion of summative and formative assessment elements, which are essential in the process of monitoring and analyzing the student's performance.

Abstract
Online booking services for accommodation have gained increasing importance in the tourist services provided by tour operators. However, one of the major difficulties associated with this process is the choice of payment method that may be appropriate to the needs and desires of tourists. In this sense, this study intends to identify the main dimensions that characterize each of the payment methods and, for each of them, seeks to characterize the tourists' perception of the main advantages and limitations associated with them. This study adopts a quantitative analysis methodology through the use of an online survey. A final sample of 238 responses was considered. The data were explored using Stata software and adopting statistical inference methods based on the analysis of variance. The findings allow us to conclude that cash payment is the payment method that simultaneously presents better availability and easiness. However, it is also the most insecure of the considered payment methods. For its part, the debit card is considered the safest method. This study didn't intend to analyze the evolution of these payment methods over time. Furthermore, other emerging payment methods such as NFC, QR codes, mobile wallets have gained recent relevance and may be interesting their inclusion in future studies. The results are mainly relevant for tourism agencies and demonstrate that tourists' perception is conditioned mainly by their age and the number of performed trips.

Abstract
Databases provide an efficient way to store, retrieve and analyze data. Oracle relational database is one of the most popular database management systems that is widely used in a different variety of industries and businesses. Therefore, it is important to guarantee that the database access and data manipulation is optimized for reducing database system response time. This paper intends to analyze the performance and the main optimization techniques (Forall, Returning, and Bulk Collect) that can be adopted for Oracle Relational Databases. The results have shown that the adoption of Forall and Bulk Collect approaches bring significant benefits in terms of execution time. Furthermore, the growth rate of the average execution time is lower for Bulk Collect than Forall. However, adoption of Returning approach doesn't bring significant statistical benefits.

Abstract
Business ideas competitions have gained increasing importance in stimulating entrepreneurial activity mainly among highly qualified graduates. However, the operating model of these competitions is quite heterogeneous, complex and often confusing, since the perception of the merit of each project is assessed differently by each jury member. Therefore, it is important to propose a decision support system that simplifies the evaluation process of competing projects and ensures all the opinions of the jury members are considered and have the same importance. The developed application uses C# and Windows Forms technologies and the AHP method to serialize competing projects according to the individual evaluation of each jury member. The results of the study allowed testing the application considering four scenarios in which the relative importance of each criterion and the performance of each project according to these criteria are changed and evaluated.
