    Testing Intra-Industry Trade Between Portugal and Spain [1990-1996]

    Get PDF
    This paper shows how, in the period 1990-1996, economic integration between the two Iberian economies has deepened through intra-industry trade. The enquiry was led at the level of the main forty traded products. In this context, several tests have been made. Our analysis combines first the application of the Grubel and Lloyd index of the main forty products and the marginal intra-industry trade of Brulhart, and Brulhart and Elliot. On the basis of these indexes we defined our criterion for the selection of the competitive cluster of Portugal throughout the period. We have also considered the global intra-industry trade, in nominal and real terms, according to the method of Greenaway et al. In econometric terms we have tried to know which is the relation between the intra-industry trade index and the marginal intra-industry trade at the level of the main forty products, the results however were not unequivocal. The same is true as far as concerns the relation between the intra-industry trade index and the net export position at the level of the same products. Despite the fact that some attempts have been inconclusive, knowledge about Iberian trade has developed in a field essential to its upgrading, and the way is open for further research.intra-industry trade; marginal intra-industry trade; competitive cluster; net export position.

    Acute Kidney Injury in the Intensive Care Unit

    Get PDF
    Acute kidney injury (AKI) is defined as an abrupt decrease in glomerular filtration rate (GFR). Incidence varies from 20% to as high as 70% in critically ill patients. Classically, AKI has been divided into three broad pathophysiologic categories: prerenal AKI, intrinsic AKI, and postrenal (obstructive) AKI. The clinical manifestations of AKI vary among a wide range of symptoms and metabolic abnormalities. A sudden decrease in GFR will result in rising concentrations of solutes in the blood, which are normally excreted by the kidneys. Recently, new urinary and serum biomarkers have gained a place in the diagnosis, classification, and prognosis prediction of AKI. The best treatment for AKI is prevention. Patients with prerenal azotemia should have intravascular volume deficits corrected and cardiac function optimized. Obstructive (postrenal) kidney disease is treated by mechanical relief of the block. The primary management of acute interstitial nephritis is discontinuation of the inciting agent. Renal replacement therapy (RRT) has emerged as a supportive mechanism rather than just as a lifesaving measure. Continuous techniques are preferable in treating critically ill patients, although every modality has its benefits, indications, and contraindications

    Tendo por objectivo a avaliação dos efeitos de alguns retardadores de crescimento no desenvolvimento vegetativo de citrinos ornamentais, para posterior utilização pelos viveiristas, foi estudado o efeito da aplicação, por pulverização, de quatro retardadores de crescimento a diferentes concentrações, sobre duas espécies do género Fortunella sp. ( F. margarita [ Lour. ] Swing. e F. Obovata Tan. ). Estudámos o efeito da daminozida a 5600, 7500 e 9400 ppm; paclobutrazol a 180, 240 e 300 ppm; CCC a 1050, 1400 e 1750 ppm e dikegulac a 3000, 4000 e 5000 ppm. O desenvolvimento vegetativo das plantas foi observado ao longo de dois ciclos de crescimento, sendo medidos os seguintes parâmetros: comprimento do ramo médio, comprimento final dos entrenós, comprimento e largura do limbo da folha média, número de folhas do ramo. Calculou-se o comprimento final do ramo e a relação comprimento/largura da folha. O primeiro crescimento não apresentou diferenças significativas em relação à testemunha, possivelmente, devido à aplicação tardia dos produtos. No segundo crescimento, as plantas tratadas com paclobutrazol foram significativamente menores, com menores entrenós e folhas mais arredondadas e mais verdes, não se verificando diferenças entre as concentrações. Tanto a daminozida como o CCC, não reduziram de forma significativa o crescimento das plantas tratadas, enquanto o dikegulac se mostrou altamente fitotóxico, nas concentrações utilizadas.info:eu-repo/semantics/publishedVersio

    DevSecOps metrics

    DevSecOps is an emerging paradigm that breaks the Security Team Silo into the DevOps Methodology and adds security practices to the Software Development Cycle (SDL). Security practices in SDL are important to avoid data breaches, guarantee compliance with the law and is an obligation to protect customers data. This study aims to identify metrics teams can use to measure the effectiveness of DevSecOps methodology implementation inside organizations. To that end, we performed a Multivocal Literature Review (MLR), where we reviewed a selection of grey literature. Several metrics purposed by professionals to monitor DevSecOps were identified and listed.info:eu-repo/semantics/acceptedVersio

    A data-driven network approach for characterization of political parties’ ideology dynamics

    This is the final published version. Available from SpringerOpen via the DOI in this record.All datasets used in this work are freely available at http://www.tse.jus.br/eleicoes/estatisticas/(in Portuguese). Intermediary files and code are available upon request to the corresponding author.Political ideology is a major social phenomena that plays a crucial role in the formation and dynamics of ideologically-aligned social groups. This alignment gives rise to some of the most powerful social structures in modern democracies, the political parties. Due to the influence and importance of political parties in society, estimating their ideology is an active topic in political science research. However ideology is a very subjective phenomena and existing quantitative methods for ideology estimation are susceptible to a variety estimation issues, specially when applied in multi-partisan systems. In this work, we developed a data-driven network model for political ideology estimation based on partisan relationships established from party-switching politicians. The model is applied to the Brazilian case and yields results consistent with existing literature in the Brazilian political scenario while addressing data scarcity issues in existing methodologies.Science Without Borders program (CAPES, Brazil)National Science Foundation (NSF)Army Research Offic

    An IT service management literature review: Challenges, benefits, opportunities and implementation practices

    Get PDF
    Information technology (IT) service management is considered a collection of frameworks that support organizations managing services. The implementation of these kinds of frameworks is constantly increasing in the IT service provider domain. The main objective is to define and manage IT services through its life cycle. However, from observing the literature, scarcely any research exists describing the main concepts of ITSM. Many organizations still struggle in several contexts in this domain, mainly during implementation. This research aims to develop a reference study detailing the main concepts related with ITSM. Thus, a systematic literature review is performed. In total, 47 articles were selected from top journals and conferences. The benefits, challenges, opportunities, and practices for ITSM implementation were extracted, critically analysed, and then discussed.info:eu-repo/semantics/publishedVersio

    Safe Crossover of Neural Networks Through Neuron Alignment

    Full text link
    One of the main and largely unexplored challenges in evolving the weights of neural networks using genetic algorithms is to find a sensible crossover operation between parent networks. Indeed, naive crossover leads to functionally damaged offspring that do not retain information from the parents. This is because neural networks are invariant to permutations of neurons, giving rise to multiple ways of representing the same solution. This is often referred to as the competing conventions problem. In this paper, we propose a two-step safe crossover(SC) operator. First, the neurons of the parents are functionally aligned by computing how well they correlate, and only then are the parents recombined. We compare two ways of measuring relationships between neurons: Pairwise Correlation (PwC) and Canonical Correlation Analysis (CCA). We test our safe crossover operators (SC-PwC and SC-CCA) on MNIST and CIFAR-10 by performing arithmetic crossover on the weights of feed-forward neural network pairs. We show that it effectively transmits information from parents to offspring and significantly improves upon naive crossover. Our method is computationally fast,can serve as a way to explore the fitness landscape more efficiently and makes safe crossover a potentially promising operator in future neuroevolution research and applications
