Abstract
This paper analyses the internationalisation of SMEs highlighting the importance of social network analysis (SNA) to display the main categories involved in SME internationalisation research. Methodologically, the paper uses a systematic review of the literature as a departure point to select the main papers on the internationalisation of SMEs and uses SNA to illustrate the main categories that have been used by researchers to identify how sectoral studies (manufacturing vs. service firms and single vs. multiple industry) have evolved and to identify the geographical origins of the papers carried out on SME internationalisation. This study is useful for researchers and academic community alike as it embeds the three main categories found (internationalisation theories, international strategy and performance) using SNA methodology.

Abstract
The data volume in organizations has grown at an ever-increasing rate and part of it is associated with the operation of the network infrastructure used to support systems and applications. Given the importance of this infrastructure for organizations and the large amount of data that their operation originates, it is fundamental to manage and monitor it so that it can perform well. The previous concern is transversal to higher education institutions, where the research team assumed as important the development of a BI/SSBI system for the Informatics and Communications Services of the institution where it operates (UTAD), which allows the managing of all data volume; that enables it to be transformed into information and knowledge, which are fundamental resources to support decision-making processes. The purpose of this article is to demonstrate the usefulness of a BI/SSBI system in the described context, therefore a system of this type is presented, along with the adopted technologies, the performed tests and the obtained results. © 2018, Springer International Publishing AG, part of Springer Nature.

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.
