We provide robust and compelling evidence of the marked impact of tertiary education on the economic growth of less developed countries and of its the relatively smaller impact on the growth of developed ones. Our results argue in favor of the accumulation of high skill levels especially in technologically under-developed countries and, contrary to common wisdom, independently of the fact that these economies might initially produce lower-technology goods or perform technology imitation. Our results are robust to the different measures used in proxying human capital and to the adjustments made for cross-country differences in the quality of education. Country-specific institutional quality, as well as other indicators including legal origin, religious fractionalization and openness to trade have been used to control for the robustness of the results. These factors are also shown to speed up technology convergence thereby confirming previous empirical studies. Our estimates tackle problems of endogeneity by adopting a variety of techniques, including instrumental variables -for both panel and cross-section analyses- and the two-step efficient dynamics system GMM.

Global wind patterns influence dispersal and migration processes of aerial organisms, propagules and particles, which ultimately could determine the dynamics of colonizations, invasions or spread of pathogens. However, studying how wind-mediated movements actually happen has been hampered so far by the lack of high resolution global wind data as well as the impossibility to track aerial movements. Using concurrent data on winds and actual pathways of a tracked seabird, here we show that oceanic winds define spatiotemporal pathways and barriers for large-scale aerial movements. We obtained wind data from NASA SeaWinds scatterometer to calculate wind cost (impedance) models reflecting the resistance to the aerial movement near the ocean surface. We also tracked the movements of a model organism, the Cory's shearwater (Calonectris diomedea), a pelagic bird known to perform long distance migrations. Cost models revealed that distant areas can be connected through"wind highways" that do not match the shortest great circle routes. Bird routes closely followed the low-cost"wind-highways" linking breeding and wintering areas. In addition, we found that a potential barrier, the near surface westerlies in the Atlantic sector of the Intertropical Convergence Zone (ITCZ), temporally hindered meridional trans-equatorial movements. Once the westerlies vanished, birds crossed the ITCZ to their winter quarters. This study provides a novel approach to investigate wind-mediated movements in oceanic environments and shows that large-scale migration and dispersal processes over the oceans can be largely driven by spatiotemporal wind patterns.

With this paper we build a two-region model where both innovation and imitation are performed. In particular imitation takes the form of technological spillovers that lagging regions may exploit given certain human capital conditions. We show how the high skill content of each region’s workforce (rather than the average human capital stock) is crucial to determine convergence towards the income level of the leader region and to exploit the technological spillovers coming from the frontier. The same applies to bureaucratic/institutional quality which are conductive to higher growth in the long run. We test successfully our theoretical result over Spanish regions for the period between 1960 and 1997. We exploit system GMM estimators which allow us to correctly deal with endogeneity problems and small sample bias.

We examine the trajectories of the real unit labour costs (RULCs) in a selection of Eurozone economies. Strong asymmetries in the convergence process of the RULCs and its components —real wages, capital intensity, and technology— are uncovered through decomposition and cluster analyses. In the last three decades, the PIIGS (Portugal, Ireland, Italy, Greece, and Spain) succeeded in reducing their RULCs by more than their northern partners. With the exception of Ireland, however, technological progress was weak; it was through capital intensification that periphery economies gained efficiency and competitiveness. Cluster heterogeneity, and lack of robustness in cluster composition, is a reflection of the difficulties in achieving real convergence and, by extension, nominal convergence. We conclude by outlining technology as the key convergence factor, and call for a renewed attention to real convergence indicators to strengthen the process of European integration.

Los nuevos hábitos de consumo de medios en el marco de la convergencia digital están propiciando un cambio en las estrategias de los medios de comunicación. Mientras unos usuarios siguen prefiriendo la radio, la televisión y la prensa tradicional para informarse otros participan de la experiencia digital en internet (blogs, redes sociales...) y dispositivos móviles, etc. En este panorama es complicado precisar dónde nace y termina el contenido o hasta qué punto es la participación del usuario quien (re) construye la información; así los contenidos mutan y se diluyen en varios soportes. En este contexto, la prensa local también vive las consecuencias del nuevo paradigma y asume los retos del reacomodo del sector ante la nueva realidad. Esta comunicación presenta las conclusiones del estudio cualitativo con entrevistas en profundidad a los responsables de medios locales en Cataluña sobre sus usuarios, contenidos y soportes en el marco de la convergencia digital.

La investigació es centra en la visió dels mitjans de proximitat i el consum de d’aquests mitjans en el marc de la convergència digital a Catalunya. No és cap misteri l’aparició de nous hàbits de consum de continguts dels mitjans de comunicació nous i vells, on uns prefereixen, la premsa, la televisió i la ràdio, i d’altres amplien l’experiència i/o prefereixen la consulta de portals web, xarxes socials o continguts per internet a través de, dispositius mòbils, consoles de vídeojocs, etc. La recerca esta està dividida en dos grans blocs: per una banda, un estudi qualitatiu amb entrevistes en profunditat als responsables de mitjans comarcals sobre la seva visió com mitjà, i la seva trajectòria, i sobre els propis lectors, radiooients, i seguidors, ; i per l’altra banda, un quantitatiu mitjançant a partir d’una enquesta online a residents a Catalunya sobre el consum de mitjans. Les conclusions mostren una radiografia de l’actual ecosistema mediàtic a Catalunya.

En l’actual context de la societat de la informació, les noves tecnologies de la comunicació i, específicament, el fenomen d’Internet, adquireixen una importància rellevant en tots els sectors socials i fan replantejar la comunicació de masses. Les característiques que ofereixen els mitjans digitals (multimedialitat, hipertextualitat, interactivitat) comporten una nova forma d’estructurar i llegir la informació. Així, capçaleres i periodistes s’han d’actualitzar en la producció de la informació i en la seva transmissió, i l’usuari ha d’aprendre noves formes de lectura per adaptar-se al nou paradigma comunicacional. D’altra banda, la societat del benestar en què vivim reclama cada cop més als mitjans de comunicació generals i també específicament als digitals que parlin de temes de salut. Aquests mitjans esdevenen fonts principals d’aquest tipus d’informació, després del metge, per a la gestió autònoma de la pròpia salut. És a partir d’aquesta convergència de mitjans digitals, periodisme i salut, de la necessitat d’explorar la situació actual i del desig d’aportar coneixements per a la millora de la pràctica professional del periodisme, que es desenvolupa el treball que es presenta en aquesta memòria. El projecte que es presenta és una anàlisi restrospectiva i descriptiva de les notícies de salut que es produeixen durant un mes als diaris digitals que publiquen en llengua catalana: El Periódico de Catalunya, l’Avui, i LaMalla.net.

The work presented here describes a part of the experience carried out during the last two academic years in a course called New Technologies Applied to Education within the Teacher Training Studies of the Faculty of Education Sciences and Psychology of the University of Girona. It is a project that involves students working on a proposal closely related to their future professional lives. In it they simulate their intervention in a school staff meeting at which the introduction of ICT into the curriculum is being discussed. This proposal is presented in a WebQuest format. Various individual and group tasks allow the students to acquire knowledge about educational programmes and resources available on the web and to discuss their possible teaching applications in the context of a specific school situation, leading to an analysis of the curricular implications associated with the educational use of the ICT from the teacher’s perspective. During the last two academic years assessments by both the students and the teaching staff have been gathered in order to redesign the proposal and calculate the time necessary for the development of each task following the ECTS system. This proposal, although formulated within the context of current degree programmes, implies a way of working guided by the plans of European convergence (ECTS). In the future it is hoped to establish an interdisciplinary proposal focusing on various subjects of the degree leading to the development of some of the capabilities established in our university’s degree courses in Early Childhood and Primary Teacher Training following the plans of European convergence (ECTS)

Durante el último medio siglo se ha producido un movimiento constante de aproximación entre las economías que hoy forman la Unión Europea. Tan sólo algunas escasas y pasajeras vacilaciones han enturbiado un proceso que ha sido intenso y persistente. El fenómeno en sí mismo ha constituido la mejor confirmación de la teoría del crecimiento neoclásica, según la cual, cuando un conjunto de economías con rasgos estructurales relativamente similares inicia un proceso de integración, es de esperar un movimiento de convergencia entre sus niveles de renta per cápita. Sin embargo, la experiencia de este pasado inmediato contrasta con momentos más remotos en el tiempo, en los cuales el incremento de intercambios entre las economías europeas no se tradujo en absoluto en una aproximación mutua. A lo largo del medio siglo anterior a la Primera Guerra Mundial, a pesar de la intensa profundización en sus relaciones, las economías europeas adolecieron de una marcada incapacidad para converger entre sí. La economía española, en concreto, mantuvo inalterada su distancia relativa con respecto a los países más desarrollados de Europa y fue incapaz de adelantarse mínimamente en la carrera del crecimiento.

L'Espai Europeu d'Educació Superior s'ha convertit en un repte, un desafiament que implica assolir una convergència de titulacions universitàries equivalents. Per això es requereix una modificació del tradicional ensenyament, en el nostre cas, de la psicologia. En aquest article s'examina l'ensenyament de la psicologia al Institute of Psychological Sciences de la Universitat de Leeds (metodologia docent; avaluació i contingut curricular)

This work considers communicative intention as the basis for rhe analysis of rhe communicative phenomenon in natural contexts. It also aims to reconcile the traditions that analyse human communication today. The convergence with the referential-ecological approach (Boada and Forns, 1989; 1997) has dealt with a number of important problems that the classic referential approach was unable to address. Its system of categories includes new variables, in addition to the classic referential variables. The cornmunicative intention is taken into account, albeit implicitly. Using a conciliatory approach, the study aims to study the intentional dimension in greater depth. The speech act theory (Searle, 1969; 1975) is used to categorize the cornrnunicative exchanges arnong a sarnple of 28 individuals and presents a certain complirnentariety with data from other traditions
