Sistema pericial para suporte à decisão na alocação de recursos de emergência

O panorama atual da emergência e socorro de primeira linha em Portugal, carateriza-se por uma grande aposta ao longo dos últimos anos num incremento contínuo da qualidade e da eficiência que estes serviços prestam às populações locais. Com vista à prossecução do objetivo de melhoria contínua dos serviços, foram realizados ao longo dos últimos anos investimentos avultados ao nível dos recursos técnicos e ao nível da contratação e formação de recursos humanos altamente qualificados. Atualmente as instituições que prestam socorro e emergência de primeira linha estão bem dotadas ao nível físico e ao nível humano dos recursos necessários para fazerem face aos mais diversos tipos de ocorrências. Contudo, ao nível dos sistemas de informação de apoio à emergência e socorro de primeira linha, verifica-se uma inadequação (e por vezes inexistência) de sistemas informáticos capazes de suportar convenientemente o atual contexto de exigência e complexidade da emergência e socorro. Foi feita ao longo dos últimos anos, uma forte aposta na melhoria dos recursos físicos e dos recursos humanos encarregues da resposta àsemergência de primeira linha, mas descurou-se a área da gestão e análise da informação sobre as ocorrências, assim como, o delinear de possíveis estratégias de prevenção que uma análise sistematizada da informação sobre as ocorrências possibilita. Nas instituições de emergência e socorro de primeira linha em Portugal (bombeiros, proteção civil municipal, PSP, GNR, polícia municipal), prevalecem ainda hoje os sistemas informáticos apenas para o registo das ocorrências à posteriori e a total inexistência de sistemas de registo de informação e de apoio à decisão na alocação de recursos que operem em tempo real. A generalidade dos sistemas informáticos atualmente existentes nas instituições são unicamente de sistemas de backoffice, que não aproveitam a todas as potencialidades da informação operacional neles armazenada. Verificou-se também, que a geo-localização por via informática dos recursos físicos e de pontos de interesse relevantes em situações críticas é inexistente a este nível. Neste contexto, consideramos ser possível e importante alinhar o nível dos sistemas informáticos das instituições encarregues da emergência e socorro de primeira linha, com o nível dos recursos físicos e humanos que já dispõem atualmente. Dado que a emergência e socorro de primeira linha é um domínio claramente elegível para a aplicação de tecnologias provenientes dos domínios da inteligência artificial (nomeadamente sistemas periciais para apoio à decisão) e da geo-localização, decidimos no âmbito desta tese desenvolver um sistema informático capaz de colmatar muitas das lacunas por nós identificadas ao nível dos sistemas informáticos destas instituições. Pretendemos colocar as suas plataformas informáticas num nível similar ao dos seus recursos físicos e humanos. Assim, foram por nós identificadas duas áreas chave onde a implementação de sistemas informáticos adequados às reais necessidades das instituições podem ter um impacto muito proporcionar uma melhor gestão e otimização dos recursos físicos e humanos. As duas áreas chave por nós identificadas são o suporte à decisão na alocação dos recursos físicos e a geolocalização dos recursos físicos, das ocorrências e dos pontos de interesse. Procurando fornecer uma resposta válida e adequada a estas duas necessidades prementes, foi desenvolvido no âmbito desta tese o sistema CRITICAL DECISIONS. O sistema CRITICAL DECISIONS incorpora um conjunto de funcionalidades típicas de um sistema pericial, para o apoio na decisão de alocação de recursos físicos às ocorrências. A inferência automática dos recursos físicos, assenta num conjunto de regra de inferência armazenadas numa base de conhecimento, em constante crescimento e atualização, com base nas respostas bem sucedidas a ocorrências passadas. Para suprimir as carências aos nível da geo-localização dos recursos físicos, das ocorrências e dos pontos de interesse, o sistema CRITICAL DECISIONS incorpora também um conjunto de funcionalidades de geo-localização. Estas permitem a geo-localização de todos os recursos físicos da instituição, a geo-localização dos locais e as áreas das várias ocorrências, assim como, dos vários tipos de pontos de interesse. O sistema CRITICAL DECISIONS visa ainda suprimir um conjunto de outras carências por nós identificadas, ao nível da gestão documental (planos de emergência, plantas dos edifícios) , da comunicação, da partilha de informação entre as instituições de socorro e emergência locais, da contabilização dos tempos de serviço, entre outros. O sistema CRITICAL DECISIONS é o culminar de um esforço colaborativo e contínuo com várias instituições, responsáveis pela emergência e socorro de primeira linha a nível local. Esperamos com o sistema CRITICAL DECISIONS, dotar estas instituições de uma plataforma informática atual, inovadora, evolutiva, com baixos custos de implementação e de operação, capaz de proporcionar melhorias contínuas e significativas ao nível da qualidade da resposta às ocorrências, das capacidades de prevenção e de uma melhor otimização de todos os tipos de recursos que têm ao dispor.

Do the most productive firms become exporters? Application of a test for the case of Portugal

Using a longitudinal database (1996-2003) at the plant level, this article aims to shed light on the proposition that most productive domestic firms self-select to export markets. Self-selection and learning by exporting are two non-mutually-exclusive theses that attempt to explain the high correlation between firms’ international trade involvement and their superior performance relative to domestic firms. In general, we find evidence of a self-selection to exports. However, there is significant heterogeneity of sales destinations, firm import status before exporting,and the specificities of the sectors firms belong to.

Which firms are the most innovative? The importance of multinationals and exporters in Portugal

We test the Global Engagement (GE) hypothesis according to which the most globally engaged firms, whether multinationals or exporters, are the most innovative. The test is applied to data from 4815 Portuguese firms for the period 2002–2004 based on the 4th Community Innovation Survey for Portugal. We estimated several Knowledge Production Functions, assuming that knowledge outputs result from the combination of certain knowledge inputs with the flow of ideas coming from the existing stock of knowledge. We found that the more internationally engaged firms create more knowledge output than their domestic counterparts; indeed, the more globalised firms apply more inputs and have the opportunity to use a larger stock of knowledge. Nevertheless, the relative perceived advantage of the more internationally exposed firms is also the result of their globalised nature,and is not directly connected with knowledge inputs or information flows.

Pilot monitoring study of ibuprofen in surface waters of north of Portugal

Ibuprofen is amongst the most worldwide consumed pharmaceuticals. The present work presents the first data in the occurrence of ibuprofen in Portuguese surface waters, focusing in the north area of the country, which is one of the most densely populated areas of Portugal. Analysis of ibuprofen is based on pre-concentration of the analyte with solid phase extraction and subsequent determination with liquid chromatography coupled to fluorescence detection. A total of 42 water samples, including surface waters, landfill leachates,Wastewater Treatment Plant (WWTP), and hospital effluents, were analyzed in order to evaluate the occurrence of ibuprofen in the north of Portugal. In general, the highest concentrations were found in the river mouths and in the estuarine zone. The maximum concentrations found were 48,720 ngL−1 in the landfill leachate, 3,868 ngL−1 in hospital effluent, 616 ngL−1 in WWTP effluent, and 723 ngL−1 in surface waters (Lima river). Environmental risk assessment was evaluated and at the measured concentrations only landfill leachates reveal potential ecotoxicological risk for aquatic organisms. Owing to a high consumption rate of ibuprofen among Portuguese population, as prescribed and nonprescribed medicine, the importance of hospitals, WWTPs, and landfills as sources of entrance of pharmaceuticals in the environment was pointed out. Landfill leachates showed the highest contribution for ibuprofen mass loading into surface waters. On the basis of our findings, more studies are needed as an attempt to assess more vulnerable areas.

Forest fires in Northern region of Portugal: impact on PM levels

Every year European citizens become victims of devastating fires, which are especially disastrous for Southern European countries. Apart from the numerous health and economic consequences, fires generate hazardous pollutants that are introduced into the environment, thus representing serious risks for public health. In that regard, particulate matter (PM) is of amajor concern. Thus, the objectives of thisworkwere to characterize the trend of forest fire occurrences and burnt area during the period of 2005 and 2010 and to study the influence of forest fires on levels of particulatematter PM10 and PM2.5. In 2010, 22,026 forest fires occurred in Portugal. The northern region was the most affected by forest fires, with 27% of occurrences in Oporto district. The annual means of PM10 and PM2.5 concentrations at two urban background sites were 25±14 μg m−3 and 8.2±4.9 μg m−3, and 17±13 μg m−3 and 7.3±5.9 μg m−3, respectively. At both sites the highest levels of PMfractionswere observed during July and August of 2010, corresponding to the periods when majority (66%) of forest fires occurred. Furthermore, PM10 daily limit at the two sites was exceeded during 20 and 5 days, respectively; 56%, and respectively 60% of those exceedances occurred during the forest fire season. Considering that the risks of forest fire ignition and severity are enhanced with elevated temperatures, the climate change might increase the environmental impacts of forest fires.

Evaluation of atmospheric deposition and patterns of polycyclic aromatic hydrocarbons in façades of historic monuments of Oporto (Portugal)

Atmospheric pollution by motor vehicles is considered a relevant source of damage to architectural heritage. Thus the aim of this work was to assess the atmospheric depositions and patterns of polycyclic aromatic hydrocarbons (PAHs) in façades of historical monuments. Eighteen PAHs (16 PAHs considered by US EPA as priority pollutants, dibenzo[a,l]pyrene and benzo[j]fluoranthene) were determined in thin black layers collected from façades of two historical monuments: Hospital Santo António and Lapa Church (Oporto, Portugal). Scanning electron microscopy (SEM) was used for morphological and elemental characterisation of thin black layers; PAHs were quantified by microwave-assisted extraction combined with liquid chromatography (MAE-LC). The thickness of thin black layers were 80–110 μm and they contained significant levels of iron, sulfur, calcium and phosphorus. Total concentrations of 18 PAHs ranged from 7.74 to 147.92 ng/g (mean of 45.52 ng/g) in thin black layers of Hospital Santo António, giving a range three times lower than at Lapa Church (5.44– 429.26 ng/g; mean of 110.25 ng/g); four to six rings compounds accounted at both monuments approximately for 80–85% of ΣPAHs. The diagnostic ratios showed that traffic emissions were significant source of PAHs in thin black layers. Composition profiles of PAHs in thin black layers of both monuments were similar to those of ambient air, thus showing that air pollution has a significant impact on the conditions and stone decay of historical building façades. The obtained results confirm that historical monuments in urban areas act as passive repositories for air pollutants present in the surrounding atmosphere.

Perspectives on access to in vitro fertilization in Portugal

OBJECTIVE: To analyze users' reasons for choosing in vitro fertilization treatment in public or private services and to identify their suggestions for improving fertility treatment. METHODS: A qualitative study using an interpretative approach was conducted. Fifteen semi-structured interviews were conducted with patients undergoing in vitro fertilization treatment (nine women, one man and five couples) at home or at their workplace in the districts of Viana do Castelo, Braga, Porto and Lisbon, Portugal, between July 2005 and February 2006. RESULTS: Users evaluated access to in vitro fertilization treatment in public and private services based mainly on their individual experiences and called for more access to less costly, faster and friendlier care with suitable facilities, appropriate time management and caring medical providers. These perceptions were also associated with views on the need for fighting stigmatization of infertility, protecting children's rights and guaranteeing sustainability of health care system. Interviewees sought to balance reduced waiting time and more attentive care with costs involved. The choice of services depended on the users' purchase power and place of residence and availability of attentive care. CONCLUSIONS: Current national policies on in vitro fertilization treatment meet user's demands of promoting access to, and quality, availability and affordability of in vitro fertilization treatment. However, their focus on legal regulation and technical-scientific aspects contrasts with the users' emphasis on reimbursement, insurance coverage and focus on emotional aspects of the treatment. The study showed these policies should ensure insurance coverage, participation of user representatives in the National Council for Assisted Reproductive Technology, promotion of infertility research and certification of fertility laboratories.

Legal and political regulation of higher education in Portugal: an evolutionary perspective on the current policy issues and the problem of order

The higher education system in Europe is currently under stress and the debates over its reform and future are gaining momentum. Now that, for most countries, we are in a time for change, in the overall society and the whole education system, the legal and political dimensions have gained prominence, which has not been followed by a more integrative approach of the problem of order, its reform and the issue of regulation, beyond the typical static and classical cost-benefit analyses. The two classical approaches for studying (and for designing the policy measures of) the problem of the reform of the higher education system - the cost-benefit analysis and the legal scholarship description - have to be integrated. This is the argument of our paper that the very integration of economic and legal approaches, what Warren Samuels called the legal-economic nexus, is meaningful and necessary, especially if we want to address the problem of order (as formulated by Joseph Spengler) and the overall regulation of the system. On the one hand, and without neglecting the interest and insights gained from the cost-benefit analysis, or other approaches of value for money assessment, we will focus our study on the legal, social and political aspects of the regulation of the higher education system and its reform in Portugal. On the other hand, the economic and financial problems have to be taken into account, but in a more inclusive way with regard to the indirect and other socio-economic costs not contemplated in traditional or standard assessments of policies for the tertiary education sector. In the first section of the paper, we will discuss the theoretical and conceptual underpinning of our analysis, focusing on the evolutionary approach, the role of critical institutions, the legal-economic nexus and the problem of order. All these elements are related to the institutional tradition, from Veblen and Commons to Spengler and Samuels. The second section states the problem of regulation in the higher education system and the issue of policy formulation for tackling the problem. The current situation is clearly one of crisis with the expansion of the cohorts of young students coming to an end and the recurrent scandals in private institutions. In the last decade, after a protracted period of extension or expansion of the system, i. e., the continuous growth of students, universities and other institutions are competing harder to gain students and have seen their financial situation at risk. It seems that we are entering a period of radical uncertainty, higher competition and a new configuration that is slowly building up is the growth in intensity, which means upgrading the quality of the higher learning and getting more involvement in vocational training and life-long learning. With this change, and along with other deep ones in the Portuguese society and economy, the current regulation has shown signs of maladjustment. The third section consists of our conclusions on the current issue of regulation and policy challenge. First, we underline the importance of an evolutionary approach to a process of change that is essentially dynamic. A special attention will be given to the issues related to an evolutionary construe of policy analysis and formulation. Second, the integration of law and economics, through the notion of legal economic nexus, allows us to better define the issues of regulation and the concrete problems that the universities are facing. One aspect is the instability of the political measures regarding the public administration and on which the higher education system depends financially, legally and institutionally, to say the least. A corollary is the lack of clear strategy in the policy reforms. Third, our research criticizes several studies, such as the one made by the OECD in late 2006 for the Ministry of Science, Technology and Higher Education, for being too static and neglecting fundamental aspects of regulation such as the logic of actors, groups and organizations who are major players in the system. Finally, simply changing the legal rules will not necessary per se change the behaviors that the authorities want to change. By this, we mean that it is not only remiss of the policy maker to ignore some of the critical issues of regulation, namely the continuous non-respect by academic management and administrative bodies of universities of the legal rules that were once promulgated. Changing the rules does not change the problem, especially without the necessary debates form the different relevant quarters that make up the higher education system. The issues of social interaction remain as intact. Our treatment of the matter will be organized in the following way. In the first section, the theoretical principles are developed in order to be able to study more adequately the higher education transformation with a modest evolutionary theory and a legal and economic nexus of the interactions of the system and the policy challenges. After describing, in the second section, the recent evolution and current working of the higher education in Portugal, we will analyze the legal framework and the current regulatory practices and problems in light of the theoretical framework adopted. We will end with some conclusions on the current problems of regulation and the policy measures that are discusses in recent years.

Master's in autonomous systems: an overview of the robotics curriculum and outcomes at ISEP, Portugal

Robotics research in Portugal is increasing every year, but few students embrace it as one of their first choices for study. Until recently, job offers for engineers were plentiful, and those looking for a degree in science and technology would avoid areas considered to be demanding, like robotics. At the undergraduate level, robotics programs are still competing for a place in the classical engineering graduate curricula. Innovative and dynamic Master’s programs may offer the solution to this gap. The Master’s degree in autonomous systems at the Instituto Superior de Engenharia do Porto (ISEP), Porto, Portugal, was designed to provide a solid training in robotics and has been showing interesting results, mainly due to differences in course structure and the context in which students are welcomed to study and work

Adaptação transcultural Portugal-Brasil do Inventário de Burnout de Maslach para estudantes

OBJETIVO: Realizar a adaptação transcultural da versão em português do Inventário de Burnout de Maslach para estudantes e investigar sua confiabilidade, validade e invariância transcultural. MÉTODOS: A validação de face envolveu participação de equipe multidisciplinar. Foi realizada validação de conteúdo. A versão em português foi preenchida em 2009, pela internet, por 958 estudantes universitários brasileiros e 556 portugueses da zona urbana. Realizou-se análise fatorial confirmatória utilizando-se como índices de ajustamento o χ²/df, o comparative fit index (CFI), goodness of fit index (GFI) e o root mean square error of approximation (RMSEA). Para verificação da estabilidade da solução fatorial conforme a versão original em inglês, realizou-se validação cruzada em 2/3 da amostra total e replicada no 1/3 restante. A validade convergente foi estimada pela variância extraída média e confiabilidade composta. Avaliou-se a validade discriminante e a consistência interna foi estimada pelo coeficiente alfa de Cronbach. A validade concorrente foi estimada por análise correlacional da versão em português e dos escores médios do Inventário de Burnout de Copenhague; a divergente foi comparada à Escala de Depressão de Beck. Foi avaliada a invariância do modelo entre a amostra brasileira e a portuguesa. RESULTADOS: O modelo trifatorial de Exaustão, Descrença e Eficácia apresentou ajustamento adequado (χ²/df = 8,498; CFI = 0,916; GFI = 0,902; RMSEA = 0,086). A estrutura fatorial foi estável (λ: χ²dif = 11,383, p = 0,50; Cov: χ²dif = 6,479, p = 0,372; Resíduos: χ²dif = 21,514, p = 0,121). Observou-se adequada validade convergente (VEM = 0,45;0,64, CC = 0,82;0,88), discriminante (ρ² = 0,06;0,33) e consistência interna (α = 0,83;0,88). A validade concorrente da versão em português com o Inventário de Copenhague foi adequada (r = 0,21;0,74). A avaliação da validade divergente do instrumento foi prejudicada pela aproximação do conceito teórico das dimensões Exaustão e Descrença da versão em português com a Escala de Beck. Não se observou invariância do instrumento entre as amostras brasileiras e portuguesas (λ:χ²dif = 84,768, p < 0,001; Cov: χ²dif = 129,206, p < 0,001; Resíduos: χ²dif = 518,760, p < 0,001). CONCLUSÕES: A versão em português do Inventário de Burnout de Maslach para estudantes apresentou adequada confiabilidade e validade, mas sua estrutura fatorial não foi invariante entre os países, apontando ausência de estabilidade transcultural.
