- Otava mental skill for sports 3 - validation and gender invariance for the portuguese versionPublication . Silva, Carlos; Torres, Diana; Louro, Hugo gonçalo Duarte; Borrego, Carla; Batista, MarcoThe aim of the study was to validate the Portuguese version of the Ottawa Mental Skills Assessment Tool (OMSAT 3p) through confirmatory factor analyses of the measurement model, and gender invariance. A total of 524 Portuguese athletes (male and female) aged between 12 and 42 years old, participated in this study (M = 19.21; SD = 5.46). The main results show that the psychometric qualities of the 48-item OMSAT 3 are adequate and that it has acceptable validity, allowing it to assess Foundation Skills (SRMR = 0.042, CFI = 0.999, TLI = 0.998, RMSEA = 0.008 and χ2 /df = 1.46), Psychosomatic Skills (SRMR = 0.056, CFI = 0.979, TLI = 0.975, RMSEA = 0.042 and χ2 /df = 1.93) and Cognitive Skills (SRMR = 0.058, CFI = 0.973, TLI = 0.968, RMSEA = 0.044 and χ2/df =1.99). This version also showed adequate values for configural, metric and scalar invariance by gender (ΔCFI < 0.01) (ΔRMSEA<0,01). The Portuguese version of the OMSAT 3 can be used with reasonable confidence to assess psychological skills in a sports context.

- Predominant technical actions used in the European judo championshipPublication . Batista, Marco; Silva, Carlos; Torres, Diana; Conceição, Ana; Borrego, Carla; Louro, Hugo Gonçalo DuarteJudo is an Olympic combat sport that is divided into male and female weight categories. Each weight category implies significant differences in technical and strategic dimensions, as well as physiological, performance, and body composition among com- petitors. This study aimed to determine the technical actions predominance used by judokas in the European Judo Championship 2021. We observed 398 judo combats, in the various weight categories male and female, disputed in the European Judo Championship 2021. It was used an observation system in accordance with the classification of judo techniques proposed by Kodokan. An observation system was used according to the Kodokan classification of judo techniques. In Nage-Waza combat, there was a predominance leg technique (Ashi-Waza), arm technique (Te-Waza), hip technique (Koshi-Waza), side sacrifice techniques (Yoko-Sutemi-Waza) and frontal sacri- fice techniques (Ma-Sutemi-Waza). When we focused our observation on the effectiveness of applied techniques, we observed more techniques scored with Ippon than Wazari. We can also observe that Shido was the significantly more recurrent punishment during male combats.
- Strategies to improve engineering student’s knowledge of emerging technologiesPublication . Metrôlho, J.C.M.M.; Prior, Stephen; Silva, CarlosThis paper describes some successful experiences within engineering departments where emerging paradigms have been used to improve student’s know-how. This experience has resulted in students with high skills in fields of high acceptance in the employment market and with experience to deal within multi-disciplinary working teams. Aspects of a case study that has involved the collaboration and supervision of staff from institutions of two countries (UK and Portugal) are reported. The work included the programming and application of handheld devices as the human-machine interface. The designed machines are mechatronic devices, to be used in Domotic (Domestic Robotic) tasks. The main focus of this paper involves the pedagogical experience, since the technical features have already been published.
- Virtual student’s zonePublication . Tojo, Gonçalo; Costa, Mónica; Metrôlho, J.C.M.M.; Silva, Carlos; Tavares, AdrianoNowadays the amount of information available on the Internet is immense and so the importance and quality of that information is questioned. Even though the amounts of available information are vast, sometimes the information useful for a specific purpose are limited. The present paper describes the development of a project in a Computer Engineering course based on this reality. The main goal to achieve is the implementation of an educational system to improve the interface between students and tutors, as well as to serve as a mean of communicating and spreading events related to computing to all members of the academic community where it is installed. The system was first built and implemented in one educational Institution but it is now improved based on the collaboration of teaching staff, of two different Portuguese institutions, with experience in teaching, allied to computer Engineering students skills and motivation. The architecture and the main features allowed by the developed system are reported through the several sections of this paper.
- Web application to help students and tutors in engineering courses: a case studyPublication . André, Gonçalo; Costa, Mónica; Metrôlho, J.C.M.M.; Silva, Carlos; Tavares, AdrianoThe present paper describes the development of an application in a Computer Engineering course using open source software tools. The main goal is the implementation of an educational system to improve the interface between students and teachers, as well as to serve as a mean of communication and events spreading related to computing to all members of the academic community where it is installed. In a first stage the system was built and implemented in one educational Institution but it is now improved based on the collaboration of teaching staff, of other Portuguese Engineering Department, allied to computer Engineering students skills and motivation. The architecture, main features, results and future work of the developed system are reported through the sections of this paper.
