    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.

    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.

    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.

    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.

    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

    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.

    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.
