  1. Gulf of Guinea maritime criminality analysis with Geographic Information Systems

    Pacheco, Miguel Bessa
    Over the past few years, the Gulf of Guinea has been increasing its world share of oil production. At the same time, armed robbery and piracy attacks have become a permanent threat to the maritime agents in the region. Oil theft, crew kidnapping for ransom and robbery of crew and ship valuables are the most common outcomes of successful attacks. To better understand the phenomena, a political, economic, social and environmental analysis of the region was perf or med, and a geographic information system was developed to provide a deeper analysis and understanding of the correlation between geographical and scope factors of this criminal activity, considering the period from January 2012 to May 2015. The system integrates the land and maritime boundaries, population, religion, oil/gas platforms,...

  4. Mapping the intellectual capital of cities and regions

    Vairinhos, Valter
    Contemporary cities or regions have complex challenges that require ongoing monitoring enabling intelligent answers in an appropriate period of time. There are many studies that indicate that this monitoring should take into account not only the tangible assets, but also the assets of intellectual capital. Several authors consider that these are the assets that are crucial either in sustainable innovation processes either in the process of developing the necessary reputation for building strong brands, able to attract talented people and investments. Based on the literature review and preliminary studies that compare the metrics for evaluating the intellectual capital of companies with the intellectual capital of...

  5. Comparative Analysis on Country Reputation through Patterns of Intellectual Capital: The case Portugal Versus Romania.

    Vairinhos, Valter
    In the last decade the world economy has undergone numerous transformations that have changed the way we evaluate the assets of organizations, cities and countries. In this context, Intellectual Capital (IC) and Knowledge Management (KM), based on the management of intangible assets, became a factor of differentiation and competitiveness. The way countries are dealing with IC and knowledge management is a decisive factor in their international reputation, which in turn acts as country branding. Country branding is the image of a nation-state and from the link between this image and the success of its economy, corresponding to its competitiveness, its richness, the efficiency of the state...

  6. Leveraging intellectual capital through Lewin’s force field analysis (the case of software development companies)

    Vairinhos, Valter
    This article outlines an original conceptual framework for the strategic management of intellectual capital assets in software development companies, interconnected with force field analysis approach. The framework allows assessing the opinions of the managers from software companies about the impact of both driving and restraining forces on the pillars of intellectual capital. Considering the capacity to adapt to change as one of the most relevant for the companies from knowledge intensive industries, this research uses a sample of 74 software development companies located in Romania to offer valuable insights on foresight capabilities to enable change benefits by managing the driving forces, respectively the restraining forces, at the level of...

  7. Resposta a incidentes de segurança da informação: uma abordagem DOTMLPI-I

    Neves, Paulo Jorge Baptista das; Correia, Fernando Jorge Ribeiro
    O conceito de ciberespaço resulta da interligação das redes de comunicações e de diferentes sistemas de informação à escala global. A abstração deste espaço de comunicações apresenta evidentes vantagens para a sociedade de informação em que vivemos. A sua utilização maciça por indivíduos e organizações fez com que ele se tornasse crítico para as empresas e para o próprio estado, pois a exploração das vulnerabilidades dos diferentes sistemas que o utilizam podem afetar as infraestruturas que prestam serviços críticos à sociedade. Para assegurar a qualidade da informação que nele circula é necessário que existam mecanismos de monitorização permanentes, com capacidade de prevenção e resposta aos incidentes que coloquem em causa a segurança da...

  8. A Marinha Portuguesa em 1914

    Pacheco, Miguel Bessa
    O desenvolvimento industrial do século XIX levou as potências europeias a olhar para os recursos naturais africanos como matéria-prima fundamental para o seu desenvolvimento económico. Portugal mantinha sob a sua soberania diversos territórios em África, desde os séculos XV e XVI, e viu os seus interesses seriamente ameaçados por terceiros. A Conferência de Berlim de 1884-1885 alterou o paradigma da soberania territorial ultramarina,obrigando à ocupação efetiva dos territórios ultramarinos. A ocupação efetiva dos territórios de interesse nacional decorreu num período de grandes dificuldades económico-financeiras.Ainda assim, diversas atividades e missões foram realizadas pela Marinha, no sentido de garantir a defesa dos interesses nacionais, tanto...

  13. Implementation of MEWMA Control Chart in Equipment Condition Monitoring

    Lampreia, Suzana Paula Gomes Fernando da SIlva; Vairinhos, Valter; Requeijo, José Gomes; Dias, J. M.
    The progressive degradation of presently operating electro-mechanical systems is a certain future fact. To minimize losses, maintenance costs and eventual replacements, condition monitoring should be applied to critical equipment (Condition Based Maintenance – CBM). The state of equipment can be predicted at any moment using statistical methods to analyze condition monitoring data. In this paper, collected data are vibration values, obtained at p points (p = 4 for instance) of an experimental equipment, forming p variables. When independence condition does not hold, it is suggested modeling data with Auto-Regressive Integrated Moving Average (ARIMA) models, and using the residues of the estimated model for Phase I. In Phase...

    Lampreia, Suzana Paula Gomes Fernando da Silva; Vairinhos, Valter; Lobo, Victor J. A. S.; Parreira, Rui; Requeijo, José Gomes
    The use of a Ship Maintenance Management System is fundamental for the good performance of equipments and the entire platform. Over the systematic maintenance, the opportunistic maintenance is a concept that aims to minimize outages and costs preventing undesirable failures. To implement this kind of maintenance statistical methodologies must be used. The Cumulative Sum charts have a very good performance applied to processes control in quality control. We proposed the use of Modified Cumulative Sum control charts to equipment maintenance.The data under study are observations of cooling water and oil temperatures from a diesel generator. In the first phase, we will apply...

  15. Control Charts Limits Flexibility Based on the Equipment Conditions

    Lampreia, Suzana Paula Gomes Fernando da Silva; Vairinhos, Valter; Lobo, Victor J. A. S.; Parreira, Rui; Requeijo, José Gomes
    Condition Based Maintenance became an important development in industrial and transport equipment maintenance efforts. Many statistical methodologies have been applied in this area. These methodologies are usually applied off-line: after the data is collected. We propose an online, real-time condition monitoring system based on a modified control chart, applied to engine parameters. These charts should be flexible enough and its control limits should reflect the equipment state, the manufacturer specifications and onboard meteorological conditions. In this study we will develop a methodology to specify flexible chart control limits. The experimental equipment is a combined diesel or gas propulsion system. Two phases...

  17. Collaborative Method to Develop an Enterprise Architecture in a Public Institution

    Roboredo, Nuno Paulo Rocha
    The growth of organizational complexity degrades business processes efficiency. Enterprise Architecture (EA) is an instrument to manage organizational complexity, through the improvement of organizational self-awareness. EA improves alignment between business and IT to ensure the business value of IT, and enables rationalization of organizational resources. However, depending of organizational culture and characteristics, there are several issues hindering the EA development within an organization. Actual frameworks, like TOGAF, require a significant number of skilled human resources (HR), which some organizations, like public institutions, cannot assign to EA activities. Our research goal is to provide an EA capability to public institutions, enabling these institutions to take advantage of EA benefits. Public institution contexts and stakeholder concerns...

  18. The Expanded Cognitive Task Load Index (NASA-TLX) applied to Team Decision-Making in Emergency Preparedness Simulation

    Marques, Mário Simões; Coelho, Denis A.; Filipe, João N. O.; Nunes, Isabel Maria Lopes
    The study demonstrates the use of the expanded TLX instrument (Helton, Funke & Knott, 2014) for cognitive and team-related workload self-assessment of 38 participants, solving the UNISDR – ONU stop disasters game simulation. Subjectsin one group (GF; n=30) performed group decision-making without prior individual practice on the simulation. A subset of GF participants (n=6) subsequently reiterated the simulation alone, reassessing their cognitive workload. Another group (IF; n=8) individually performed the simulation and reiterated it in groups. Most GFparticipants, moving from group to singly conditions, reported decreasing physicaland temporal demands, unchanged self-assessed performance, and increased mentaldemands, effort and frustration. IF participants incurred...
