Abstract
Investments in cross-border electricity interconnections are key for the integration of the European energy market. To analyze policy frameworks for these decisions, we model two settings for the expansion of transmission capacity between two regions, where the volume of investment is agreed upon through either Nash-Coase or Nash bargaining. For each setting we provide fair share cost allocation solutions, respectively with and without compensations. Each region has its own TSO, maximizing social welfare within its geography, and the markets are modeled with linear supply and demand curves, with trade enabled by the interconnection. The results of the application of the models to the Iberian market suggest their ability to estimate realistic values for the capacity of cross-border interconnection between two regions.

Abstract
This article performs an exploratory study of the potential of flow theory and FLIGBY game to contribute to develop entrepreneurship competencies among higher education students. For this purpose, this study considers the use of a focus group consisting of eight students enrolled in the entrepreneurship course in a higher educational institution in Portugal, in which students for two months explored FLIGBY. The results obtained allowed us to conclude that FLIGBY was also suitable to be explored in the context of entrepreneurship classes. Students emphasized the potential of the game to be applied for training of management skills, the recognition of their leadership skills, and the exploration of new approaches to the management challenges. Finally, it should be noted that the benefits offered by FLIGBY were experienced differently by students with professional experience in IT and management fields. Those students emphasized the application of the game to the real world and the potential offered for FLIGBY for allowing students to explore new skills and actions.

Abstract
This study investigates the main motivations, difficulties and good practices in the migration process of software development models from Waterfall to Agile experienced by IT Portuguese companies. For that, we adopted a quantitative methodology based on multiple case studies that allowed us to explore five research questions. In a first step, we propose to identify the main reasons that motivate the companies to adopt Agile development processes and we intend to characterize this migration process. We also explore a set of good practices that can be followed in this migration process and we suggest a set of measures that can be used to assess the success of projects in an Agile environment. Finally, we explore the organizational and management impacts with the introduction of Agile processes.

Abstract
Increasingly social networks are used both in the personal and professional levels, being companies and employees also exposed to the risks posed by them. In this sense, it is relevant to analyze employees' perception of the risks and vulnerabilities posed by the use of social networks in corporate environments. For this purpose, a questionnaire was developed and distributed to 372 employees of small and medium-sized companies that allowed the characterization and analysis of those risks. The results indicate that the security risks are perceived moderately by employees, emphasizing the risk of defamation and cyberbullying as being the most pertinent. On the other hand, the findings indicate that older employees, the existence of lower academic qualifications, and those working in medium-sized companies are more aware of these risks.

Abstract
The paper introduces the Active and Permanent Information System Management Model (MGSI-AP). It results from an investigation that discussed concepts and perspectives about Information Management, positioning it as a transversal and applied area within Information Science, focused on info communicational flow, in a complex institutional context the Portuguese public University and related information services. The University is assumed in a complex and systemic double facet, between the formal organized system and the loosely coupled combinatory system. Here is presented one of the operationalization axes of the performed research and model. It highlights the close connection between Information Management and the area of studies of Information Production, framed by a theoretical-methodological proposal and operational modeling, which converge to an Information Management definition and the design of a Matrix of Components and Variables under analysis.
