This paper analyzes the impact of students' proactivity on academic performance based on a sample from students enrolled in an introductory course of Political Economy at the University of Seville (Spain) in three consecutive courses (2014-2015, 2015-2016 and 2016-2017). Proactivity is measured by several indicators, such as class attendance, case-study oral presentation and its delivery in a foreign language, all of them being non-mandatory activities for students who have participated in the experiment. Specifically, this study aims to assess the impact of a student's proactivity on two academic outcomes: (i) to pass or fail the exam; and (ii) the score obtained. Impact assessment has been performed using a probit and ordered multinomial logit models. The results show that a student's proactivity measured by class attendance and case-study presentation significantly increases the probability of passing the exam, while the impact of using a foreign language seems to be non-significant. In relation to the score obtained, the proactivity measured through the case presentation raises the probability of obtaining a higher mark more than regular class attendance.

“…After that, the token itself is used to obtain further scoped tokens to be used to access to the different services. Nonetheless, the techniques described in the previous study 55 also could be applicable. In such a case, both the network and computation times would be significantly reduced.…”

“…However, in production environments, where the RP must contact a remote IDP, we can expect an average network time between both entities of ≈550 ms, as described in another study. 55 Hence, in production environments, the total time would likely be increased up to ≈1650 ms. Given the expected benefits of integrating OpenStack with ABFAB-based federations in terms of security, usability, and user management simplification, we consider this is a reasonable amount of time as it will hardly be noticed by end users.…”

Identity federations enable users, service providers and identity providers from different organizations to exchange authentication and authorization information in a secure way. In this paper we present a novel identity federation architecture for cloud services based on the integration of a cloud identity management service with an Authentication, Authorization and Accounting (AAA) infrastructure. Specifically we analyse how this type of AAA-based federation can be smoothly integrated into OpenStack, the leading open source cloud software solution, using the IETF Application Bridging for Federated Access Beyond web (ABFAB) specification for authentication and authorization. We provide details of the implementation undertaken in GÉANT s CLASSe project, and show its validation in a real testbed.
