    Output and inflation responses to credit shocks: are there threshold effects in the euro area?

    Get PDF
    This paper investigates whether output and inflation respond asymmetrically to credit shocks in the euro area. The methodology, based on a non-linear VAR system, follows work by Balke (2000) for the US. The results reveal evidence of threshold effects related to credit conditions in the economy. Consistent with this finding, the impulse responses show some signs of asymmetric responses over the lending cycle.

    Aggregate loans to the euro area private sector

    Get PDF
    This paper provides new evidence on the behaviour of euro area aggregate loans to the private sector. Using a sample covering the last twenty years, a cointegrating vector linking the real stock of loans to a small set of domestic macroeconomic variables is found. Besides real GDP and prices, this set includes a new measure of the cost of loans obtained as a weighted average of bank lending rates. The results are overall encouraging, though the recursive estimates of the long-run parameters suggest that in 2000 some disturbances, probably of a temporary nature, affected the system. The study then addresses the issue of the leading indicator properties of loans. It finds that the deviations of the real stock of loans from the equilibrium level implied by the model seem to contain information on future changes in inflation, though not on its level.

    Modelling the demand for loans to the private sector in the euro area

    Get PDF
    This paper studies the determinants of loans to the private sector in the euro area. Using the Johansen methodology, the study identifies one cointegrating relationship linking real loans, GDP and interest rates. This relationship implies that in the long-run real loans are positively related to real GDP and negatively to real short-term and long-term interest rates. Both the signs and the magnitude of the coefficients suggest that the cointegrating vector describes a long-run demand equation. The short-run dynamics of the demand for euro area real loans is subsequently modelled by means of a Vector Error Correction Model (VECM). A number of specification tests performed on the VECM produce satisfactory results, with tests of stability of the model parameters showing no signs of structural breaks during the sample period (1980 Q1 - 1999 Q2). All of this suggests that developments in real loans to the private sector in the euro area can be reasonably explained by the model JEL Classification: C32, C51

    Get PDF
    In this chapter we discuss recent developments and challenges in European media and communication policy, focussing on the period since the 2008 global financial crisis. We are especially interested in the implications of the financial crisis and its political repercussions nationally (austerity measures and cuts to public services as well as growing anti-politics sentiments and widespread dissatisfaction with free-market capitalism and representative democracy) for media and communication policy, understood here in a broad sense, so to include all electronic communications, such as the Internet, mobile communications, social media etc. Our overarching concern is with the implications of developments in media and communication policy for the democratic functions of the media in Europe

    Anais do II SeminĂĄrio SeminĂĄrio Estadual PIBID do ParanĂĄ: tecendo saberes / organizado por Dulcyene Maria Ribeiro e Catarina Costa Fernandes — Foz do Iguaçu: Unioeste; Unila, 2014Tendo em vista que muitos alunos tĂȘm dificuldade de resolver equaçÔes quadrĂĄticas utilizando fĂłrmulas matemĂĄticas nĂłs, futuros professores, devemos buscar outras formas de resolução para alterar esse quadro na educação bĂĄsica do Brasil, buscando novos conceitos e implantando-os dentro das escolas para tentar melhorar o ensino, e mostrar aos alunos que a matemĂĄtica nĂŁo Ă© monĂłtona e cheias de formulas complicadas. HĂĄ vĂĄrias resoluçÔes que deviriam ser mais trabalhadas em sala de aula, como o mĂ©todo de completar quadrados, o conceito geomĂ©trico tambĂ©m deve ser mais abordado no ensino mĂ©dio do paĂ­s. Existem vĂĄrios tipos de resoluçÔes que nos permitem solucionar equaçÔes do segundo grau, por exemplo, utilizando formas geomĂ©tricas que ajudam a compreender os problemas, esse artigo vai relatar uma dessas formas aplicada em sala de aula, e como foi a recepção do aluno com esse mĂ©todo diferenciado de aprendizage

    Reduction of pollutants emissions on si engines : accomplishments with efficiency increase

    Get PDF
    This paper presents an experimental study aiming to identify the means to minimize the reduction of the overall performance of a gasoline engine when employing the Exhaust- Gas Recirculation (EGR) technique that reduces NOx emissions. The increase of the compression ratio and turbocharging was evaluated as a mean to recover the original performance. The formation of pollutants and the engine performance were verified at full and partial loads. The results show that the combination of exhaust gas recirculation with turbocharger or through an increase of the compression ratio enhance the relation between the engine performance and the emission of NO. However, the turbocharger seemed to be more sensitive to the negative effects of the EGR technology

    Tracking Dengue Epidemics using Twitter Content Classification and Topic Modelling

    Full text link
    Detecting and preventing outbreaks of mosquito-borne diseases such as Dengue and Zika in Brasil and other tropical regions has long been a priority for governments in affected areas. Streaming social media content, such as Twitter, is increasingly being used for health vigilance applications such as flu detection. However, previous work has not addressed the complexity of drastic seasonal changes on Twitter content across multiple epidemic outbreaks. In order to address this gap, this paper contrasts two complementary approaches to detecting Twitter content that is relevant for Dengue outbreak detection, namely supervised classification and unsupervised clustering using topic modelling. Each approach has benefits and shortcomings. Our classifier achieves a prediction accuracy of about 80\% based on a small training set of about 1,000 instances, but the need for manual annotation makes it hard to track seasonal changes in the nature of the epidemics, such as the emergence of new types of virus in certain geographical locations. In contrast, LDA-based topic modelling scales well, generating cohesive and well-separated clusters from larger samples. While clusters can be easily re-generated following changes in epidemics, however, this approach makes it hard to clearly segregate relevant tweets into well-defined clusters.Comment: Procs.

    Trabalho de ConclusĂŁo de Curso (Graduação)Klebsiella pneumoniae tem sido caracterizado como causador de doenças e responsĂĄvel isua resistĂȘncia aos antibiĂłticos. Este trabalho como objetivo caracterizar amostras clĂ­nicas de Klebsiella pneumoniae quanto Ă  produção de enzimas do tipo KPC. Foram avaliados 30 isolados em 28 pacientes, em um hospital mineiro, no perĂ­odo de 2013 a 2015. As amostras foram isoladas e recuperadas para realização da tĂ©cnica de PCR para detecção do gene blaKPC. Foi demonstrado maior associação da Diabetes tipo Mellitus com infecção por K. pneumoniae, na Unidade de Terapia Intensiva, bem como maior resistĂȘncia frente a Tobramicina, Ticarcilina + Ácido ClavulĂąnico, fora da UTI. Foi confirmada a presença do gene blaKPC em 92,8% das amostras. A pesquisa demonstrou ainda que a maior parte dos isolados Ă© resistente a pelo menos um antimicrobiano de cada classe, com exceção de Polimixina B. Por isso sĂŁo necessĂĄrios estudos que monitorem a evolução clonal destes microrganismos no ambiente hospitalar, nĂŁo somente em K. pneumoniae, mas em todos os outros com emergĂȘncia a multirresistĂȘncia

    Trabalho de conclusĂŁo de curso (graduação)—Universidade de BrasĂ­lia, Faculdade de CiĂȘncias da SaĂșde, Departamento de FarmĂĄcia, 2020.A Leucemia LinfoblĂĄstica Aguda (LLA) Ă© uma neoplasia maligna que afeta a linhagem progenitora de linfĂłcitos e carece de marcadores laboratoriais para melhor estratificação prognĂłstica. A famĂ­lia PDLIM Ă© uma famĂ­lia de proteĂ­nas de andaime (scaffold proteins) com os domĂ­nios PDZ e LIM em sua estrutura e Ă© composta por seis membros no genoma humano, sendo estes PDLIM1, PDLIM2, PDLIM3, PDLIM4, PDLIM5 e PDLIM7. Existem evidĂȘncias da relação entre os membros dessa famĂ­lia e alguns tipos de cĂąnceres sĂłlidos e hematolĂłgicos da linhagem mieloide. Por isso, neste trabalho o objetivo foi comparar o padrĂŁo de expressĂŁo dos membros dessa famĂ­lia em cĂ©lulas obtidas da medula Ăłssea (MO) de indivĂ­duos saudĂĄveis e em amostras de indivĂ­duos subdivididos em oito tipos de LLA. AlĂ©m disso, discutir o possĂ­vel papel da famĂ­lia PDLIM na fisiopatologia dessa doença. Interessantemente, os pacientes com LLA apresentam expressĂŁo reduzida dos genes PDLIM1, PDLIM4 e PDLIM5. NĂŁo encontramos diferença de expressĂŁo dos genes PDLIM2, PDLIM3 e PDLIM7 entre as amostras leucĂȘmicas e controle. Importante destacar que para alguns tipos de cĂąncer existem apontamentos para uma possĂ­vel função de PDLIM como gene supressor tumoral. Acreditamos que essa função possa ocorrer tambĂ©m na LLA e destacamos que a LLA t(1:19) Ă© o subtipo leucĂȘmico que mais sofre influĂȘncia da famĂ­lia PDLIM, tendo em vista que todos os genes analisados (exceção de PDLIM 7) estĂŁo com expressĂŁo reduzida nesses pacientes. Mais estudos sĂŁo necessĂĄrios para validar nossa anĂĄlise e descrever funcionalmente o papel dessa famĂ­lia na LLA
