- Filmes (Ir)refletidosPublication . Pereira, Ana Catarina; Nogueira, LuísFilmes (Ir)refletidos propõe uma dúzia de textos de investigadores/as de diversas áreas dos estudos fílmicos, os quais propõem variadas abordagens, tendo como mote comum as relações entre o cinema e a filosofia, o qual suscitou as jornadas realizadas na UBI em 2017, que estiveram na origem da presente edição. A pluralidade de perspetivas e propostas é acompanhada pela multiplicidade temática, pela individualidade estilística e pela variedade de obras e cineastas estudados, os quais vão de Van Sant a Hitchcock, de Bergman a Kubrick, de Tocha a Farhadi, de Scorsese a Brakhage. Incidindo ou partindo de domínios tão diferentes como a ética ou a fenomenologia, a estética ou a epistemologia, os estudos queer ou as teorias dos cineastas, e adotando discursos que podem ir do epistolar ao ensaístico, cada texto oferece um caminho singular para pensar o cinema – e, por isso, o livro se revela de uma grande abertura –, mas articulando-se com os demais no domínio circunscrito da reflexão filosófica – e, desse modo, encontra a sua coerência.
- Pacing behaviour of players in team sports: Influence of match status manipulation and task duration knowledgePublication . Ferraz, Ricardo; Gonçalves, Bruno; Coutinho, Diogo; Marinho, Daniel; Sampaio, Jaime; Marques, MCThe study aimed to identify the influence of prior knowledge of exercise duration associated with initial information about momentary match status (losing or winning) on the pacing behaviour displayed during soccer game-based activities. Twenty semi-professional male players participated in four game scenarios divided in two sessions. In the first game scenario, players were not informed about the time duration or initial match status. In the second, players were only informed they would be required to play a small-sided game for 12 minutes. In the third, players were told they would play a small-sided game for 12 minutes and that one of the teams was winning 2 to 0. Finally, in the fourth game scenario, players were instructed they would play a small-sided game for 12 minutes and the score lines used at the start of the previous game scenario were reversed. The results showed a tendency for the unknown task duration to elicit greater physical responses in all studied variables, compared with knowing the task duration. Knowing the task duration and starting the game winning or losing did not affect the players' activity profile between the two conditions. Thus, during small-sided soccer games, knowledge (or not) about the exercise duration alters the pacing behaviour of the players. Moreover, short and undisclosed-length exercise durations resulted in the adoption of more aggressive pacing strategies, characterised by higher initial exercise intensities. Furthermore, previous information on match status does not seem to interfere with pacing patterns if the players are aware of the exercise duration. Coaches may use knowledge of exercise duration to manipulate the small-sided games' demands.
- A Satisfação dos Utentes da Consulta Externa num Hospital PúblicoPublication . Almeida, Anabela; Amorim, J. P.A satisfação é um componente importante na prestação de cuidados de saúde de qualidade. A satisfação é uma experiência multifactorial e multidimensional sendo por isso difícil definir critérios concretos que conduzam a uma melhoria dos indica- dores de satisfação dos utilizadores dos cuidados de saúde. Nos últimos anos, a satisfação tem sido um hot topic em diversos sectores nomea- damente no da saúde. Apesar de intensa pesquisa os fatores preditivos que melhor se correlacionam com a satisfação e preferência dos utentes ainda se encontram mal esclarecidos. [...]
- Entrepreneurship Education and Training as Facilitators of Regional Development: A Systematic Literature ReviewPublication . Galvão, Anderson Rei; Ferreira, João José de Matos; Marques, CarlaPurpose - The purpose of this paper is to provide insights of a systematic literature review (SLR) of the entrepreneurship education and training as facilitators of regional development. Current and future trends in the field are identified. Design/methodology/approach – The paper offers an SLR on the entrepreneurship education and training and advances through a comprehensive bibliometric analysis comprising the period 1973-2016. To collect data, only articles published in scientific journals were used in the SCOPUS database. Findings – The results highlight that both training and entrepreneurship education can be a strong strategic tool for regional development, and that it is important for entities such as academia, government and business to cooperate towards the same goal in order to strengthen the entrepreneurial intention of society. Findings reveal three clusters as trends of literature: entrepreneurial universities, entrepreneurial spirit and process of business creation. Originality/value – This paper contributes to fill the gap in terms of SLR on the importance of entrepreneurship education and training for regional development conducted by a bibliometric analysis. Keywords Entrepreneurship, Regional development, Bibliometric analysis, Systematic literature review, Education and training, Entrepreneurial universities
- Permeable pavements – green infrastructures as a flood mitigation measurePublication . Afonso, Márcia Isabel Lopes; Almeida, Marisa S. Dinis; Fael, Cristina Maria SenaPermeable asphalt pavements have been one of the solutions used to increase the permeability of road pavements given the growing urbanization and climate change. The high porosity and permeability of surface layers with PA (porous asphalt) mixtures allows the water infiltration and, consequently, reduces superficial runoff and contributes to the recharge of underground aquifers. However, the infiltration capacity may be impaired by clogged pores with sediments. The double layer porous asphalt (DLPA) was developed to mitigate this effect. This is a key issue in the pavements’ service life. Information on the clogging processes in these layers is not yet well characterized. The study was carried out using a rainfall simulator in order to generate design storm events with a known intensity and duration. The experimental methodology adopted took into account different phases of evaluation of the infiltration capacity with two clogging cycles (500 and 1000 g m-2). The DLPA infiltration capacity was evaluated in the different phases after different precipitation events (100, 200 and 300 mm h-1). The results showed that, in general, the double layer porous asphalt has the capacity to drain the water, even after clogging and with lower voids content. The infiltration capacity was partially restored when subjected to simple maintenance.

- “Less is more”: Simplifying point clouds to improve grasping performancePublication . Lopes, Vasco; Alexandre, Luís; Fernandes, MiguelObject grasping is a task that humans do without major concerns. This results from self learning and by observing of other skilled humans doing such task with previous information. However, grasping novel objects in unknown positions for a robot is a complex task which encounters many problems, such as sub-optimal performance rates and the time consumption. In this paper we present a method that complements the state-of-the-art grasping algorithms with two segmentation steps, the first one which removes the largest planar surface in the point cloud of the world before the grasp detector receives them and the second one that complements this segmentation with another segmentation that calculates where the object is located and segments the point cloud by executing a crop around the object. The proposed method significantly improves the grasping success rate (100% improvement over the baseline approach) and simultaneously is able to reduce the time consumption by 23%.
- p53 as the Focus of Gene Therapy: Past, Present and FuturePublication . Valente, Joana; Queiroz, João; Sousa, FaniSeveral gene deviations can be responsible for triggering oncogenic processes. However, mutations in tumour suppressor genes are usually more associated to malignant diseases, with p53 being one of the most affected and studied element. p53 is implicated in a number of known cellular functions, including DNA damage repair, cell cycle arrest in G1/S and G2/M and apoptosis, being an interesting target for cancer treatment.
