  • Leadership and organizational innovation in the third sector: A systematic literature review
    Publication . Adro, Francisco José Nave do; Leitão, João
    The impact of the global recession has served to increase pressure on non-profit organizations resources. Executive leadership is an essential component of the success of these institutions. The two-fold purpose of this article is to provide a state-of-the-art overview about the existing literature on leadership and organizational innovation in the third sector, as well as to identify research gaps leading to a research model, which can be used in further empirical research. For this, we used the collection of existing literature in the Web of Science. The 144 articles selected in the database were analysed using the VOSviewer software. Results show a concern with the renewal of management bodies and a lack of qualified leaders. This study contributes to the construction of an action agenda leading to the establishment of new leadership and organizational innovation model for the third sector.

  • Application of an Unmanned Aircraft System in Search and Rescue Missions
    Publication . Santos, Luís Eduardo da Costa; Silva, Jorge Miguel dos Reis; Ribeiro, Pedro Alexandre Maia
    It is known that the quickness and effectiveness of Search and Rescue (SAR) missions are crucial to their success. This study has the purpose of understanding how the application of an Unmanned Aircraft System (UAS) in SAR missions, could bring improved outcomes and be an added value to the procedures that are already performed by SAR teams. In this study, the results were obtained by performing a series of field trials, based on the recreation of real SAR scenarios and the implementation of an operational plan proposal, with recordings of time lapses at different phases of the operation. The reports of the real scenarios were provided by the teams of the Grupo de Intervenção, Proteção e Socorro (GIPS), who are under the command of the Unidade de Intervenção (UI), specialized in this type of missions. Both GIPS and UI are dependent on Tenente General Comandante Geral of the Guarda Nacional Republicana (GNR). A survey developed by the National Aeronautics and Space Administration (NASA) was also applied at the end of each trial in order to evaluate the workload index of the participants in the trials. Throughout this research, conclusions are obtained taking into account the difference of an UAS operation between day and night periods, the improvements to the current procedures, but also the limitations of this system, such as the measures that should be taken when this system is applied in SAR missions. Conclusions were also based on the replies to the surveys. The focus of this case study was the use of an UAS in SAR missions performed in a mountain environment, well known by its adverse weather conditions. This study proved that, under these kinds of conditions, the use of the UAS was not always possible due to their own limitations and the validation of the proposed operational plan was obtained.
