Abstract
Filter-bank Multicarrier Modulation (FBMC) is a 5G waveform candidate with improved spectral efficiency and out-of-band emissions performance compared to OFDM. To address the challenge of designing flexible hardware infrastructures for future wireless communications, this paper presents a dynamically reconfigurable FPGA-based Frequency Spreading FBMC (FS-FBMC) baseband modulator. Based on a detailed modulator datapath analysis, the proposed architecture combines static multi-mode modules with dynamic partial reconfiguration (DPR) to achieve a flexible and evolvable system. Results show that our design is resource-efficient, due to hardware virtualization. Moreover, low-latency reconfiguration of static multimode modules combined with ICAP overclocking results in submillisecond reconfiguration times which are viable in the context of flexible communication systems, such as Cognitive Radios.

Abstract
The diffusion and adoption of e-participation contributes to better democracy and more participative societies. Nevertheless, despite the potential benefits of e-participation, the level of citizen satisfaction regarding the use of e-participation and its effects on the continued intention to use have not been widely assessed yet in the literature. This article proposes a conceptual model that integrates the DeLone & McLean success model, that assesses the citizen satisfaction regarding the perception of the e-participation system quality; the expectation-confirmation model for the continued intention to use, which evaluates satisfaction based on the confirmation of ex-post experience on e-participation use and the perceived usefulness; and the dimensions of sense of place, which play a moderator role between the citizen satisfaction and the e-participation use. © 2018, Springer International Publishing AG, part of Springer Nature.

Abstract
This chapter analyzes the challenges faced by a glass bottle manufacturer when incorporating the research, development, and innovation (RDI) standards into the firm's integrated management systems. Based on a case study, this chapter explores how the firm managed to incorporate the new standards into the already set of integrated management system based on the ISO 9001, ISO 14001, and OHSAS 18001 standards that the firm has managed to internalize in its continuous improvement process. In order to incorporate this new RDI management system, the firm developed a set of three procedures that involve an ideas management and opportunity evaluation procedure, a production knowledge interface management procedure, and an RDI project management system. These three procedures are now internalized as part of the integrated management system. © 2018, IGI Global.

Abstract
The large amount of Recommender System algorithms makes the selection of the most suitable algorithm for a new dataset a difficult task. Metalearning has been successfully used to deal with this problem. It works by mapping dataset characteristics with the predictive performance obtained by a set of algorithms. The models built on this data are capable of predicting the best algorithm for a new dataset. However, typical approaches try only to predict the best algorithm, overlooking the performance of others. This study focus on the use of Metalearning to select the best ranking of CF algorithms for a new recommendation dataset. The contribution lies in the formalization and experimental validation of using Label Ranking to select a ranked list of algorithms. The experimental procedure proves the superior performance of the proposed approach regarding both ranking accuracy and impact on the baselevel performance. Furthermore, it draws and compares the knowledge regarding metafeature importance for both classification and Label Ranking tasks in order to provide guidelines for the design of algorithms in the Recommender System community.

Abstract
This study follows an interpretivist approach and showcases five testimonials of technology usage in everyday life, in Rio de Janeiro, Brazil; the research also brings forward the perspectives of 31 other Brazilian citizens. The informants are Brazilian Master's level students who were on an exchange program to Portugal, at a major Portuguese university. Brazil, and in particular Rio de Janeiro, the focus of this study, are seen to have talented people and to be also open to technology - on the developing side as well as on the user side. Trust issues still exist - concerning e-commerce - and may indeed be pervasive in society. Brazil is currently undergoing a profound social and economic crisis, which it is trying to recover from. Indeed, the general lack of safety and security felt in Rio de Janeiro may even be a reason for the popularity of home and work deliveries - so that citizens will not have to travel - with travel constituting an additional risk which many may prefer to avoid. Thus, technology (a diverse set of apps) may be serving an additional purpose - that of ensuring security in daily life in Brazil.

Abstract
The Portuguese footwear industry is aware that success in the value chain is directly tied to information sharing and the development of collaborative networks, which are consequences of the constant rapid market changes. In this paper a state-of-the-art of the Portuguese footwear sector is presented, giving special focus to the cluster of Felgueiras and the good practices that are applied to it. Next, B2B and eCommerce domains will be discussed, as well as the good practices and information systems that support them. Afterwards, a list of functional and non-functional requirements, which have been validated and prioritized using a case studies approach, will be presented. Finally, it will be presented a non-functional prototype for an eC-B2B platform for the footwear sector.
