- Contributions for best practices in social recruitment: pilot study in the Northern Region of PortugalPublication . Silva, Marlene; Gomes, RuiRecruitment is based on a conglomerate of techniques and procedures put in place to attract qualified. The recruitment process has suffered changes, becoming even more sophisticated, involving a whole organisation and a whole community. A new source of recruitment has emerged with the use of online social networks using facilitators in its development and usage, allowing the search for candidates to be fast, cheap and "global". In Portugal, the information available and studies conducted into this phenomenon are still irrelevant, with little reported on the importance of online social recruitment. The purpose of this article is to contribute to what is understood by the professional process of recruitment through online social media by recruitment companies in the Northern Region of Portugal, analysing the use of online media by recruitment professionals, facilitator support tools and the associated best practices.
- A New ROV Design: Issues on Low Drag and Mechanical SymmetryPublication . Gomes, Rui; Fraga, Sérgio; Sousa, Alexandre; Fraga, Sérgio Loureiro; Martins, Alfredo; Sousa, J. Borges de; Pereira, Fernando LoboThis paper reports the design of a new remotely operated underwater vehicle (ROV), which has been developed at the Underwater Systems and Technology Laboratory (USTL) - University of Porto. This design is contextualized on the KOS project (Kits for underwater operations). The main issues addressed here concern directional drag minimization, symmetry, optimized thruster positioning, stability and layout of ROV components. This design is aimed at optimizing ROV performance for a set of different operational scenarios. This is achieved through modular configurations which are optimized for each different scenario.
- Perceptions of music students about the effects of loud music and protective practicesPublication . Rodrigues, Matilde; Silva, Mariana; Silva, Paula; Gomes, Rui; Prior, Ana; Ignacio, OctavioAs with professional musicians, also students can be exposed to dangerous sound pressure levels in the course of their academic activity, which can result in hearing damages. However, there are very few studies focused on the problem of music students’ exposure to loud music, particularly about the students’ perceptions and behaviours. In view of this, this study attempts to analyse the perceptions of the students about loud music risks, as well as to characterize their preventive behaviours and health effects. To analyse this issue, a questionnaire was developed and applied to music students of a secondary school. 123 students participated in the study. The results showed that most of students perceive ensemble classes and group study as noisy. However, several students assessed the sound levels in the different classes and in the additional study as low or moderate. Brass and percussion were identified as the noisiest instruments and strings were perceived as producing low and moderate sound pressure levels. The results also showed that only a part of the students were concerned with the health effects related to the exposure to high sound levels and the majority reported do not use hearing protection, since they never tried to use it or they seen it as non-necessary. The findings of this study showed that music students are not entirely aware of the risks associated with the exposure to high noise levels in the course of their practice and a strategy to improve protective behaviours need to be implemented in the music schools.
