    Airport Competition and Aviation Network Evolution: an Exploratory Study on Continental Portugal
    ( 2011) Jorge Pinho de Sousa ; Edgar Ramiro Jimenez ; João Claro
    This work describes an exploratory study to examine the evolution of the aviation network of three airports in continental Portugal - Lisbon, Faro and Porto - between 2001 and 2010. Our main goal is to evaluate the influence that decisions taken in a given airport have over decisions made in other airports in the network. Additionally, the research shows the relationship between airport competition and the changes occurring in the aviation network during the period of study. A conceptual framework on airport competition is also presented in order to define the ways in which airports compete and the relationships between them. We evaluate the degree of concentration of the aviation network using the Network Concentration Index (NC). Similarly, we analyse planning documents produced by the operator of the airports, to assess how aware they are on airport competition and on the strategies proposed for their airports.

    Developing training applications for hydrogen emergency response training
    ( 2019) Pinto,D ; Bruno Miguel Peixoto ; Goncalves,G ; Miguel Correia Melo ; Vasco Amorim ; Maximino Bessa ; 6184 ; 5095 ; 5408 ; 7926
    Virtual Reality (VR) has been evolving over the years, becoming more and more accessible, in a wide area of applications. One of these areas where VR can have a major impact is training and certification. Hydrogen vehicles are becoming a reality and first responders still lack proper tools and resources to train emergency responses for the purpose. VR can play here a crucial role in ensuring a proper hydrogen emergency response training due to the advantages associated with VR training programs such as resource optimization, repeatability, and replicability. This paper proposes using VR for hydrogen emergency response training by developing a solution composed of three components: tutorial mode, training mode, and certification mode. A usability study is further conducted to evaluate its usability and user satisfaction. The results show that the use of this application regards usability and user satisfaction were extremely positive. © 2019 IEEE.

    ENTREPRENEURIAL POTENTIAL IN ENGINEERING AND BUSINESS COURSES - WHY WORRY NOW?
    ( 2008) Aurora Teixeira
    In this paper we analyze the magnitude of this propensity in engineering and economics/business courses. The reason for such focus is that traditionally these courses are viewed as the ones concentrating individuals that are more likely to create new ventures. The empirical results, based on a large-scale survey of 2430 final-year students, reveal that no statistical difference exists in entrepreneurial potential of economics/business and engineering students, and that these two latter groups have lower entrepreneurial potential than students from other courses. This result proves to be quite unfortunate given the focus that previous studies have placed on these two majors, and the fact that a substantial part of entrepreneurial education is undertaken in business and engineering schools.

    HUMAN CAPITAL, TRADE AND LONG-RUN PRODUCTIVITY. TESTING THE TECHNOLOGICAL
    ( 2007) Natércia Fortuna ; Aurora Teixeira
    An important characteristic of the role of foreign trade in the technological catch-up of countries is the complementary nature of technological change and human capital formation. Education is likely to have a crucial impact on total factor productivity because it determines the capacity of an economy to adopt and to implement efficiently technology from abroad. However, the role of human capital as a pre requisite for technology absorption although theoretically acknowledged has been empirically neglected. Empirical studies in this domain do not clearly test the mechanisms through which trade affects total factor productivity of a given country. Using cointegration techniques, we demonstrate that the interaction between human capital and machinery imports is the most critical determinant of Portuguese long-run total factor productivity.

    An introductory course on Decision Support Systems based on solving small management problems
    ( 2012) Jorge Pinho de Sousa ; João Claro
    In this paper we describe our experience in teaching an introductory course on Decision Support Systems to students with quite heterogeneous backgrounds and often with a low quantitative education. This course was designed based on 'active learning' principles and is structured around the resolution of small management problems. Some years of experience have shown the potential of this approach, with an average excellent performance of the students.

    Rekindle dynamics: validating the pressure on wildland fire suppression resources and implications for fire management in Portugal.
    ( 2012) João Claro ; Abilio Pereira Pacheco ; Tiago Oliveira
    Rekindles can represent a high burden on wildland fire suppression resources, but despite the relevance of this phenomenon in Portugal, related research is still scarce. Seeking to contribute to address this gap, the purpose of this study was to organize and provide an overview of the problem of rekindles in Portugal, and to verify whether evidence exists that the high proportion of rekindles in Portugal is related to the double duty of Portuguese firefighters to perform initial attack and mop-up operations. Our study included informal meetings, formal recorded interviews, dispatch centre visits, actual rekindle observation, and an analysis of the National Forest Authority database. From the study of genealogies of rekindles, we concluded that 17.2% additional forest fires (rekindles in successive generations) had their origin in only 7.4% of primary fires. Through linear regression analysis, we found that their proportions increase in days with more occurrences, preliminarily sup

    A review essay on child well-being measurement: uncovering the paths for future research.
    ( 2011) Liliana Fernandes ; Américo Mendes ; Aurora Teixeira
    The research on indicators on the state of child well-being is a growing field and one that has experienced several changes through time. Due to the growing supply of data on children, and in order to facilitate conclusions and tracking trends, researchers have been led to develop child well-being summary indexes. Several proposals have already been presented. In the present work, we critically review the most prominent summary child well-being indexes recently constructed, the Index of Child and Youth Well-Being in the United States, the Child Well-being Index for the European Union, the Microdata Child Well-Being Index, and the Deprivation Index. The examination is carried out according to the contributions and innovations the indexes have brought to the field. A critical assessment of the methods used in the construction of the indexes is made and their main limitations identified. Accordingly, some future lines of research to improve child well-being measurement through summary indexes are put forward.

    Simulation analysis of a wildfire suppression system
    ( 2012) Tiago Oliveira ; Abilio Pereira Pacheco ; João Claro
    Rekindles and false alarms are unusually high in the Portuguese wildfire management system, representing a high burden on suppression resources in particular, and fire management resources in general. In 20,049 occurrences that the suppression system handled in the summer of 2010, 12.5% were false alarms and 15.0% were rekindles. We present a discrete-event simulation model of a wildfire suppression system, designed to analyze the joint impact of primary fires, rekindles and false alarms on system performance. The work contributes to fill a research gap concerning that impact, and features a novel application of simulation to suppression systems, as screening tools to support more holistic analyses. The model was implemented in ®ARENA, and used for a study of a Portuguese district. We found that reducing false alarms and rekindles to benchmark values would significantly reduce pressure on firefighting teams, enabling more effective suppression operations.

    SPIN-UP - creating an Entrepreneurship Coaching and Training Program for University Spin-Offs
    ( 2012) Marko Torkkeli ; Sanna Tomperi ; Dariusz Tzmrielak ; Milton Sousa ; Gonçalo Meireles ; Manuel Au-Yong Oliveira ; João José Ferreira ; Alexandra Xavier ; José Carlos Caldeira ; Marina van Geenhuizen ; Qing Ye ; Arthur Tolsma ; Pekka Salmi
    This SPIN-UP project has been funded with support from the European Commission and is a study involving research performed in 4 countries: Finland, the Netherlands, Poland, and Portugal. The SPIN-UP research question is: What sort of entrepreneurship training and coaching program will contribute to the development of key entrepreneurial skills, both technical and behavioural, essential to enable and leverage university spin-off (USO) growth? The aim of the SPIN-UP study was to picture key entrepreneurial skills and their contribution to the performance of university spin-off firms, as well as missing skills, in order to develop an effective training and coaching program. USO, entrepreneurial firms that bring university knowledge to market, do not traditionally grow very much and we sought to contribute to a countering of this trend. To avoid a large differentiation in firm age, firm age limits were set at 2 years (lower limit) and 10 years (higher limit). 10 years was however used flexibly, particularly in those sectors where development and bringing products to market goes relatively slowly, like in the medical life sciences and material (nano) science (15 years used as the maximum in these cases). The research to date has involved a total of 64 interviews and questionnaires in the four countries mentioned above. The preliminary comparative analysis revealed that the four countries studied show somewhat different skill sets, meaning that we may still be in a World where diff

    Supply Chain Strategy in High-Tech Start-ups
    ( 2012) João Claro ; Ana Cristina Barros
    Supply chain management is recognized as an important source of competitive advantage, but has mostly been studied in mature companies, and almost neglected for start-ups. We contribute to address this gap in understanding the role of supply chain strategy in start-ups, with an exploratory multiple case study of three high-tech manufacturing new ventures. Our results suggest that high-tech start-ups exploit supply chain management related competitive advantages, and their strategic choices evolve as the new ventures develop from a start-up phase to a scale-up phase.
