Shock Transmission Mechanism of the Economic Crisis in East Asia : An Application of International Input-Output Analysis

This paper investigates the impacts of the 2008 economic crisis on industries in East Asia. By using the updated Asian international input-output table for 2008, the paper attempts to identify the transmission mechanism and the magnitude of impact of the crisis on industries in East Asia. The analyses reveal that the crisis significantly affected industrial output of the nine East Asian countries. In particular, the countries which are deeply involved in production networks were affected most seriously. Moreover, the analyses show that the impact was transmitted to East Asian industries considerably through the “triangular trade”, in which China imports parts and components from neighboring East Asian countries and then exports final products to the U.S. and EU markets.

Innovation networks in China, Japan, and Korea : further evidence from U.S. patent data

The growing importance of innovation in economic growth has encouraged the development of innovation capabilities in East Asia, within which China, Japan, and Korea are most important in terms of technological capabilities. Using U.S. patent data, we examine how knowledge networks have developed among these countries. We find that Japan's technological specialization saw gradual changes, but those of Korea and China changed rapidly since 1970s. By the year 2009, technology specialization has become similar across three countries in the sense that the common fields of prominent technology are electronics and semiconductors. Patent citations suggest that technology flows were largest in the electronics technology, pointing to the deepening of innovation networks in these countries. Together with our prior work, the Japanese and U.S. data produce similar conclusions about innovation networks.

A combined measure for quantifying and qualifying the topology preservation of growing self-organizing maps

The Self-OrganizingMap (SOM) is a neural network model that performs an ordered projection of a high dimensional input space in a low-dimensional topological structure. The process in which such mapping is formed is defined by the SOM algorithm, which is a competitive, unsupervised and nonparametric method, since it does not make any assumption about the input data distribution. The feature maps provided by this algorithm have been successfully applied for vector quantization, clustering and high dimensional data visualization processes. However, the initialization of the network topology and the selection of the SOM training parameters are two difficult tasks caused by the unknown distribution of the input signals. A misconfiguration of these parameters can generate a feature map of low-quality, so it is necessary to have some measure of the degree of adaptation of the SOM network to the input data model. The topologypreservation is the most common concept used to implement this measure. Several qualitative and quantitative methods have been proposed for measuring the degree of SOM topologypreservation, particularly using Kohonen's model. In this work, two methods for measuring the topologypreservation of the Growing Cell Structures (GCSs) model are proposed: the topographic function and the topology preserving map

Realización de Mapa Estratégico de Ruido de las Carreteras de la Red del Estado (A-3 - zona Campus Sur de la U.P.M.)

En cumplimiento de la Directiva 2002/49/CE en lo referente a carreteras, se han llevado a cabo en España, en el año 2007, los mapas estratégicos de ruido (MER) de los grandes ejes viarios de más de 6 millones de vehículos / año (datos 2006). En esta categoría se encuentra la carretera A-3 a su paso por el Campus Sur de la U.P.M. De acuerdo con el pliego de prescripciones técnicas, estos MER se dividen en fase A o de estudio básico y fase B o de estudio de detalle. En el proyecto denominado “Realización de Mapa Estratégico de Ruido de las carreteras de la Red del Estado (A-3 - Zona Campus sur de la U.P.M.)” se muestran los resultados de información pública de fase A del Mapa Estratégico de Ruido (MER) para la carretera A-3 en la Comunidad de Madrid. Teniendo en cuenta dichos resultados y la no elección del Campus Sur en la fase B (detalle) de dicho MER; en el presente proyecto se realiza el Mapa Estratégico de fase B del Campus Sur de la U.P.M. para el gran ejes viarios (A-3), de cumplimiento de la Directiva 2002/49/CE y siguiendo las indicaciones del pliego de prescripciones técnicas para esta primera fase de entregas de 2007 y utilizando para ello Sistemas de Información Geográfica (SIG). Se justifica, según los resultados obtenidos, si hubiera sido necesaria su inclusión en esta fase de estudio. Una vez establecidas las diferencias entre Mapa Estratégico de Ruido (MER) y Mapa de Ruido (MR), se analizan los diversos criterios técnicos que debe tomar un consultor acústico durante la realización de un MER y cómo estos pueden afectar al resultado final siendo todos ellos válidos pero creando una falta de homogeneidad entre los diferentes MER según el autor del estudio. Se describen las diferentes acciones que se están tomando tras la entrega de 2007 para intentar solucionar este problema de cara a las nuevas entregas. ABSTRACT: The environmental Noise Directive 2002/49/EC has clear requirements to Member States in terms of Strategic Noise Maps according to roads. So, have been carried out in Spain, in 2007, Strategic Noise Maps of the major roads which have more than six million vehicle passages a year (2006 data) where the A-3 road near “Campus Sur U.P.M.” is included. In accord with the statement of technical requirements, these Strategic Noise Maps are divided into A phase (Basic study) and B phase (detailed study). The present project by the name of "Implementation of Strategic Noise Map of Spanish Roads (A-3 – Campus Sur U.P.M. area)" shows the results of Strategic Noise Map for the A-3 in the Community of Madrid (A phase, public information – EGRA project Spanish Ministry of Transport). According to de study results and the not election of “Campus Sur” to B phase (detail), in this project has been made the B phase of Strategic Map in compliance with Directive 2002/49/EC, following the technical requirements specifications for the first phase of deliveries (2007) and using Geographic Information Systems (GIS) to carry on them. Is justified, in accordance with the results, if it was necessary to include “Campus Sur” in this B phase of study. Once established the differences between Strategic Noise Map and Noise Map, the present project examines the technical criteria that must take an acoustic consultant for the realization of a Strategic Map and how these criteria could affect the quality of the final results being all of them valid but it generate a lack of homogeneity between the different Strategic Noise Map by the author of the study. There wasn’t so much experience in Spain in the methodology proposed by the European Noise Directive. The actions that are being taken after delivery of 2007 to try to solve this problem and get harmonized the results among the whole network for the new deliveries each five years are shown at the present project.
