The term Big Data is being used widely by companies and researchers who consider your relevant functionalities or applications to create value and business innovation. However, some questions arise about what is this phenomenon and, more precisely, how it occurs and under what conditions it can create value and innovation in business. In our view, the lack of depth related to the principles involved in Big Data and the very absence of a conceptual definition, made it difficult to answer these questions that have been the basis for our research. To answer these questions we did a bibliometric study and extensive literature review. The bibliometric studies were realized based in articles and citation of Web of Knowledge database. The main result of our research is the providing a conceptual definition for the term Big Data. Also, we propose which principles discovered can contribute with other researches that intend value creation by Big Data. Finally we propose see the value creation through Big Data using the Resource Based View as the main theory used for discuss that theme.

A liderança vem sendo estudada há muitos e muitos anos, porém o foco desses estudos sempre esteve no líder em si. Nosso trabalho investiga o que há além do líder. O objetivo foi verificar como o comportamento do líder pode influenciar a comunicação de seus colaboradores em microempresas. Para atingir esse objetivo fizemos um estudo quantitativo sobre as redes sociais dos líderes e de seus seguidores em duas empresas do estado de São Paulo. Como principal resultado desse estudo, propomos que um líder que concentra as decisões de uma empresa em sua imagem, cria um centro comunicacional pequeno e pode provocar uma baixa comunicação entre a sua equipe. O líder que delega as decisões entre sua equipe, tende a possuir um centro comunicacional maior e sua equipe passa a se comunicar com maior densidade. Palavras-chave: Liderança; redes sociais; comunicação organizacional.
ABSTRACTLeadership has been studied for many, many years, but without focus on the leader itself. Our work investigates what is beyond the leader. The objective was to verify how the behavior of the leader can influence a communication of its collaborators. For a quantitative goal on social networks of leaders and their followers in two small companies. As the main result of this study, we propose that a leader who consumes the decision of a company in his image, creates a small communication center and can cause low communication between his team. The leader who delegates decisions to his team has a larger communicational center and his team communicates more strongly.
