  • The Influence of Relational Capital on Product Innovation Performance at Innovative SMEs
    Publication . Dorrego, Pedro Figueroa; Costa, Ricardo; Fernández, Carlos Fernández-Jardon
    The authors build on the intellectual capital and new product development perspectives to study the influence of relational capital on product innovation performance. An empirical research was conducted, using a questionnaire administered to Portuguese innovative SMEs. The results suggest that relational capital does have a positive effect on product innovation performance. In particular, ”Vertical relationships” stands out as the main relational capital element significantly affecting product innovation at the innovative SMEs level. The existence and proactive management of relationships with customers and suppliers emerge as critical factors to product innovation success. We find our results to be useful for both researchers and practitioners: at the intellectual capital level, we contribute to the ongoing understanding of relational capital’s impact on critical business activities; at the product innovation level, we contribute to the identification of additional critical success factors for new product development. At a time when intellectual capital and product innovation management are both considered to be critical for companies to gain a competitive edge (and even survive) in today’s unstable business environment, this study contributes to acknowledge the relevance of relational capital management on product innovation success at innovative SMEs.

  • Comparison between aerobic power parameters at different time-averaging intervals in swimming: An update
    Publication . Sousa, Ana; Jesus, Kelly; Figueiredo, Pedro; Sousa, Marisa
    Sousa et al. (Open Sports Sci J, 3: 22 – 24, 2010) showed that different time averaging intervals lead to distinct VO2 values in a maximal 200m front crawl effort, evidencing higher VO2 values for breath-by-breath sampling, and differences between this latter data acquisition and all the other less frequent time intervals studied (5, 10, 15 and 20 s). These are interesting outputs in the field of exercise physiology applied to swimming once: (1) VO2 assessment is conducted in a swimming pool with a portable gas analyser which allowed breath-by-breath measurements, and not in a swimming flume with a Douglas bag technique or mixing chamber analyser, as traditionally occurs, and (2) the comparison between different time-averaging intervals used to remove breath-by-breath fluctuations during exercise periods has remained neglected, in sport in general and swimming in particular. Therefore, in the present study, we investigate the influence that different time averaging intervals have in aerobic power related parameters (VO2peak and VO2max). Ten subjects performed 200m front crawl effort at supra-maximal intensities (all-out test) and other ten subjects performed 200m front crawl effort at maximal aerobic intensities (100% of VO2max).The intensity at which the 200m front crawl was performed (supra-maximal and maximal intensities) had a significant effect on VO2peak and VO2max values obtained for each averaging intervals studied.
