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.

Abstract
The recognition of emotions in spoken words is one of the most important aspects in human communication and social relationships. Traditional approaches to the study of vocal emotional recognition involve instructing listeners to choose which one of several words describing emotion categories best characterize linguistically neutral utterances or vocalizations uttered by actors portraying various emotional states. To this end, generic experiment control software is usually used, which has some disadvantages. In this paper, we present a system that digitalizes the whole process involved in understanding how people perceive and understand vocal emotions, improving data collection, processing and analysis. Moreover, this system provides a new group of features that allows a more comprehensive characterization of the behavioral dimension underlying vocal emotional recognition. In this paper we describe this system and analyze the relationship between emotional perception, gender, age and Human-Computer Interaction.

Abstract
The smart places are vulnerable with corrupted or compromised data, with the false integration of new devices, and devices with firmware versions inconsistent. These risks worsen with the increasing volume and diversity of data, devices, infrastructures and users connected to the Web. The systematic review of the literature were selected 190 documents, which reveals the growing interest on the theme of blockchain technology with the publication of 14 documents in 2014 to about 100 already in 2017. The articles focused on the areas bitcoin (about 40%), IoT (about 30%), financial (about 15%), cryptocurrencies, electronic government (about 12%), smart contracts, smart cities, business (with about 10% each) and health (about 5%). This perspective confirms the generic model study data supported in blockchain technology for smart places, especially when applied to smart cities and the specific field of the mobility ecosystem, with the use of the new concepts of the application of blockchain in IoT, smart contracts and e-governance. © 2018, Springer International Publishing AG, part of Springer Nature.

Abstract
Millennials interact with technology like no other generation before them and this is affecting how they want to be taught in higher education and how they want to lead and expect to be led in organizations, after graduating. Though stating that they want to be enlightened in academia, some qualitative comments from millennials indicate the opposite, namely that they want to be prepared but also to be kept naive as to what business really entails. This is expected to help keep motivation levels high, as motivation is seen to be the key element to success in life. Millennials expect also to be led authentically and to be treated as valued human beings. This is in contrast to the current autocratic leadership profile found predominantly in Portuguese organizations, at the time of writing. This study had a sample of one hundred and eleven millennial students who answered a survey on attitudes towards leadership and their desired approach to higher education. Three interviews with seasoned executives were also performed, to establish a contrast and see other perspectives. With this research, we conclude that we may be in the presence of a hard working millennial generation, contrary to previous research findings which has indicated that they are lazy. Finally, information technology (IT) is a precious partner in class, in particular Padlet.com, Moodle, and online News Forums, as well as the challenge to create original videos about course content. Future research should focus on how technology has made society more transparent with employees wanting more democratic leaders in times when hierarchies are seen to hinder rather than aid productivity levels.
