Non-linear adjustment of import prices in the European Union

This paper focuses on the non-linear adjustment of import prices in national currency to shocks in exchange rates and foreign prices measured in the exporters' currency of products originating outside the euro area and imported into European Union countries (EU-15). The paper looks at three different types of non-linearities: a) non-proportional adjustment (the size of the adjustment grows more than proportionally with the size of the misalignments); b) asymmetric adjustment to cost-increasing and cost-decreasing shocks, and c) the existence of thresholds in the size of misalignments below which no adjustment takes place. There is evidence of more than proportional adjustment towards long-run equilibrium in manufacturing industries. In these industries, the adjustment is faster the further away current import prices are from their implied long-run equilibrium. In contrast, a proportional linear adjustment cannot be rejected for some other imports (especially within agricultural and commodity imports). There is also strong evidence of asymmetry in the adjustment to long-run equilibrium. Deviations from long-run equilibrium due to exchange rate appreciations of the home currency result in a faster adjustment than those caused by a home currency depreciation. Finally, we also find that adjustment takes place in the industries in our sample only when deviations are above certain thresholds and that these thresholds tend to be somewhat smaller for manufacturing industries than for commodities.exchange rate adjustment; monetary union;

Business Cycles and Macroeconomic Policy Coordination in Mercosur

Abstract: The paper analyzes cyclical comovements in the Mercosur area differentiating idiosyncratic from common shocks. In the Mercosur (or any region for that matter) shocks can be country-specific, affecting only one country or a specific set of countries (for example, a weather-related shock, a domestic policy shock); or they can be common to the entire region (for example, a change in the conditions in international capital markets or a world recession). Propagation mechanisms, in turn, are important because a shock that was initially country-specific, originating in one country, might eventually spillover to others. We build on the unobserved component approach to decompose the Mercosur countries’ real GDP (seasonally adjusted) uctuations into these three components and compare them with previous results. The main findings in the paper are: first, common factors originating in impulses stemming from changes in investor’s sentiment are relevant to explaining regional output comovements and the spillover effects between neighbors are significant. Second, volatility matters, and matters especially in the case of recent regional agreements. Supply shocks in Mercosur countries tend to be larger than in the US and European countries. Third, finance matters for both volatility and output/price dynamics. Accelerator effects may be important in explaining some features of the output/price dynamics that the standard models based on vector autoregression techniques are unable to account forBusiness cycle, Comovement, Mercosur, OCA, Policy coordination

3D Well-composed Polyhedral Complexes

A binary three-dimensional (3D) image $I$ is well-composed if the boundary surface of its continuous analog is a 2D manifold. Since 3D images are not often well-composed, there are several voxel-based methods ("repairing" algorithms) for turning them into well-composed ones but these methods either do not guarantee the topological equivalence between the original image and its corresponding well-composed one or involve sub-sampling the whole image. In this paper, we present a method to locally "repair" the cubical complex $Q(I)$ (embedded in $\mathbb{R}^3$) associated to $I$ to obtain a polyhedral complex $P(I)$ homotopy equivalent to $Q(I)$ such that the boundary of every connected component of $P(I)$ is a 2D manifold. The reparation is performed via a new codification system for $P(I)$ under the form of a 3D grayscale image that allows an efficient access to cells and their faces

The changes to accounting education and accounting educators as a result of changes in the Spanish University system : a case study using an institutional theory approach

Accounting education is part of the wider system of higher education provision that in many individual countries has been the subject of an increasing rate of change but it is unclear to what extent these external changes have influenced the delivery of accounting education. The paper uses an institutional theory approach (Meyer & Rowan, 1977; DiMaggio & Powell, 1983; Powell & DiMaggio, 1991) to analyse the pressures exerted by the external institutional constituents on the Spanish higher education system in order to implement the European Higher Education Area. Specifically, the paper analyses the changes caused by these pressures on accounting education, as well as the reactions and behaviours of accounting educators to those changes. It is based on a longitudinal case study at the Department of Accounting of the University of Seville. The case study uses multiple sources including interviews, participant observation, informal discussions and documents. The results evidence the importance of coercive isomorphism on the structuring of the Spanish university system, some factors that have hindered the development of the normative isomorphism in accounting education, and the relevance of regulatory legitimacy to academic career prospects of accounting educators

E-PUR: An Energy-Efficient Processing Unit for Recurrent Neural Networks

Recurrent Neural Networks (RNNs) are a key technology for emerging applications such as automatic speech recognition, machine translation or image description. Long Short Term Memory (LSTM) networks are the most successful RNN implementation, as they can learn long term dependencies to achieve high accuracy. Unfortunately, the recurrent nature of LSTM networks significantly constrains the amount of parallelism and, hence, multicore CPUs and many-core GPUs exhibit poor efficiency for RNN inference. In this paper, we present E-PUR, an energy-efficient processing unit tailored to the requirements of LSTM computation. The main goal of E-PUR is to support large recurrent neural networks for low-power mobile devices. E-PUR provides an efficient hardware implementation of LSTM networks that is flexible to support diverse applications. One of its main novelties is a technique that we call Maximizing Weight Locality (MWL), which improves the temporal locality of the memory accesses for fetching the synaptic weights, reducing the memory requirements by a large extent. Our experimental results show that E-PUR achieves real-time performance for different LSTM networks, while reducing energy consumption by orders of magnitude with respect to general-purpose processors and GPUs, and it requires a very small chip area. Compared to a modern mobile SoC, an NVIDIA Tegra X1, E-PUR provides an average energy reduction of 92x

HOW ARE THE FORMAL AND INFORMAL ONLINE SUPPORTS OF MENTAL HEALTH ACCESSIBLE FOR REFUGEES AND THEIR CHILDREN IN CANADA?

Refugees fleeing from extreme human rights violations are highly vulnerable and predisposed to a variety of mental health illnesses. The issue that this study addresses are the barriers refugees encounter when navigating mental health resources in Canada. Across the literature it has been found that refugees tend to underutilize mental health resources for a variety of reasons despite their poor mental health outcomes. Some factors of underutilization include, linguistic, religious, cultural, and economic (Chaze et al., 2015). To address this problem, the purpose of this study will be to evaluate the online accessibility of available resources. A content analysis on the Ontario and British Columbia settlement websites was conducted. This paper will address the following research questions: (1) What are the formal and informal support channels for the mental health of refugees? (2) What services are provided by these supports to serve the mental health of refugees? and (3) What are the online barriers refugees may face when navigating these websites? This data led to the following themes: Government versus NGOs, Type of Services Offered, and Online Barriers. These themes are useful to understand the gaps in the literature that indicate refugees underutilize mental health resources. Furthermore, it will provide insight as to why refugees may undergo hardship when navigating mental health websites

Structure, kinetic characterization and subcellular localization of the two ribulose 5-phosphate epimerase isoenzymes from Trypanosoma cruzi

The enzyme of the pentose phosphate pathway (PPP) ribulose-5-phosphate-epimerase (RPE) is encoded by two genes present in the genome of Trypanosoma cruzi CL Brener clone: TcRPE1 and TcRPE2. Despite high sequence similarity at the amino acid residue level, the recombinant isoenzymes show a strikingly different kinetics. Whereas TcRPE2 follows a typical michaelian behavior, TcRPE1 shows a complex kinetic pattern, displaying a biphasic curve, suggesting the coexistence of -at least-two kinetically different molecular forms. Regarding the subcellular localization in epimastigotes, whereas TcRPE1 is a cytosolic enzyme, TcRPE2 is localized in glycosomes. To our knowledge, TcRPE2 is the first PPP isoenzyme that is exclusively localized in glycosomes. Over-expression of TcRPE1, but not of TcRPE2, significantly reduces the parasite doubling time in vitro, as compared with wild type epimastigotes. Both TcRPEs represent single domain proteins exhibiting the classical α/β TIM-barrel fold, as expected for enzymes with this activity. With regard to the architecture of the active site, all the important amino acid residues for catalysis -with the exception of M58- are also present in both TcRPEs models. The superimposition of the binding pocket of both isoenzyme models shows that they adopt essentially identical positions in the active site with a residue specific RMSD < 2Å, with the sole exception of S12, which displays a large deviation (residue specific RMSD: 11.07 A). Studies on the quaternary arrangement of these isoenzymes reveal that both are present in a mixture of various oligomeric species made up of an even number of molecules, probably pointing to the dimer as their minimal functional unit. This multiplicity of oligomeric species has not been reported for any of the other RPEs studied so far and it might bear implications for the regulation of TcRPEs activity, although further investigation will be necessary to unravel the physiological significance of these structural findings.Fil: Gonzalez, Soledad Natalia.
