Trend analysis in two standard growth models
This paper analyzes the trend processes characterized by two standard growth models using simple econometrics. The first model is the basic neoclassical growth model that postulates a deterministic trend for output. The second model is the Uzawa-Lucas model that postulates a stochastic trend for output. The aim is to understand how the different trend processes for output assumed by these two standard growth models determine the ability of each model to explain the observed trend processes of other macroeconomic variables such as consumption and investment. The results show that the two models reproduce the output trend process. Moreover, the results show that the basic growth model captures properly the consumption trend process, but fails in characterizing the investment trend process. The reverse is true for the Uzawa-Lucas model.Uzawa-Lucas model, basic neoclassical growth model, trend process, cointegration
Cyclical Features of Uzawa-Lucas Endogenous Growth Model
This paper analyzes the cyclical properties of a generalized version of Uzawa-Lucas endogenous growth model. We study the dynamic features of different cyclical components of this model characterized by a variety of decomposition methods. The decomposition methods considered can be classified in two groups. On the one hand, we consider three statistical filters: the Hodrick-Prescott filter, the Baxter-King filter and Gonzalo-Granger decomposition. On the other hand, we use four model-based decomposition methods. The latter decomposition procedures share the property that the cyclical components obtained by these methods preserve the log-linear approximation of the Euler-equation restrictions imposed by the agent’s intertemporal optimization problem. The paper shows that both model dynamics and model performance substantially vary across decomposition methods. A parallel exercise is carried out with a standard real business cycle model. The results should help researchers to better understand the performance of Uzawa-Lucas model in relation to standard business cycle models under alternative definitions of the business cycle.endogenous growth, decomposition methods, cyclical features
Instalación de una planta satélite de almacenamiento y regasificación de GNL (previa a la cogeneración)
D’una manera genèrica es dóna el nom de Planta Satèl·lit de GNL al conjunt
d’instal·lacions d’emmagatzemat i regasificació destinades al subministrament de gas
natural per consums locals situats en zones abastades per xarxes de gas natural
canalitzat, i en les que l’abastament s’efectua mitjançant la descà rrega de cisternes que
per via terrestre transporten el GNL des d’una planta d’abastament de major entitat.
En el present projecte no tracta de l’abastament a una població amb gas natural sinó que
tracta del disseny d’una Planta Satèl·lit de GNL amb l’objecte d’abastar a uns motors
amb el fi de produir energia.
El projecte conté una memòria a on es fa una descripció de l’emmagatzemat,
descà rrega, regasificació i de les instal·lacions complementà ries com l’estació de
regulació i mesura (ERM), l’odorització i el sistema de control, a més d’un manual de
funcionament de la planta.
A més de la memòria, es proposa la base de cà lcul per les pèrdues de cà rrega i dià metre
de canonades, un pressupost i un annexa amb plĂ nols i fotografies. Els plĂ nols contenen
una localització, un diagrama de flux del procés i un plà nol de l’ERM i les fotografies
són de cada element que constitueix la instal·lació
Nuevas aportaciones al estudio de la platerĂa vallisoletana y su difusiĂłn en la ciudad de Toro
El estudio en profundidad del centro platero de Toro está arrojando interesantes datos acerca de su vinculaciĂłn con la platerĂa vallisoletana. Las especiales circunstancias que se dieron en la ciudad a lo largo de la Edad Moderna, facilitaron desde fecha temprana la llegada y asentamiento de artĂfices de la provincia de Valladolid y de los propios talleres capitalinos, estableciendo asĂ unas prĂłsperas relaciones entre ambas platerĂas. Más allá de catalogar obras y autores, este artĂculo profundiza en aspectos como la influencia artĂstica, la importaciĂłn de piezas o las repercusiones que para un centro de segundo orden como Toro tuvieron estos vĂnculos. El estudio se completa con la presentaciĂłn de una serie de piezas, en gran nĂşmero inĂ©ditas, punzones y aportes documentales sobre Ă©stas y sobre el trabajo de aquellos artĂfices vallisoletanos en tierras de Zamora.An in-depth study of the silversmith center of Toro is giving us interesting details about his relationship with the silversmith centre of Valladolid. The special circumstances that took place in the city throughout the Modern Age, facilitated from an early date the arrival and settlement of different authors from Valladolid's province and al so from de capital workshops, establishing in this way prosperous relations between both centres. Beyond cataloguing pieces and authors, this article deepens in other aspects like the artistic influence, the importation of pieces or the repercussions that these links had for a second-rate center like Toro. The study is completed with the presentation of several pieces, many of them unpublished, silvermarks and documental contributions about these and the work of those silversmiths of Valladolid in Zamora's lands
The evolution of foreign language learning from a diachronic perspective
The present project offers a linguistic theoretical approach about foreign language teaching methodologies based on English in regard to the importance that English has gained throughout the last decades. This paper portrays a vision of the current situation of English as well as it reviews many different methods of teaching a second or foreign language, paying especial attention to Communicative Language Teaching, analysing from a diachronic perspective their corresponding impact and development. The final aim of this dissertation is to provide a critical review of traditional teaching approaches in order to propose some potential improvements on methodologies teaching English as a foreign language.El presente trabajo brinda una base teĂłrica lingĂĽĂstica sobre diversos tipos de metodologĂa y enseñanza en lenguas extranjeras basándonos en el inglĂ©s debido a la importancia que ha cobrado en las pasadas dĂ©cadas. Este TFG ofrece una visiĂłn de la actual situaciĂłn del inglĂ©s asĂ como de diversos mĂ©todos de enseñanza de un segundo idioma, con especial atenciĂłn al mĂ©todo comunicativo (CLT), analizando desde una perspectiva histĂłrica el impacto de los mismos y su evoluciĂłn. El objetivo final de este trabajo es proyectar una perspectiva crĂtica de estos mĂ©todos de enseñanza con el fin de proponer posibles mejoras respecto a la enseñanza del inglĂ©s como segundo idioma.Departamento de FilologĂa InglesaGrado en Estudios Inglese
