Estudio comparativo de conocimientos y percepciones ambientales sobre la Reserva de la Biosfera de Sian Ka'an entre estudiantes de primaria de comunidades maya, México

El estudio analiza y compara las percepciones y conocimientos ambientales que estudiantes de primaria del municipio maya de Felipe Carrillo Puerto tienen sobre la vecina Reserva de la Biósfera de Sian Ka’an (RBSK) en términos de biodiversidad, con el fin de evaluar y elaborar programas de Educación Ambiental (EA) dirigidos a promover la protección de este espacio natural. Se analizan dibujos, cuestionarios y encuestas recogidos en tres comunidades maya que difieren en su proximidad a la RBSK y en su nivel de urbanización. Los resultados indican que los niños en general desconocen la RBSK y la biodiversidad de la zona. Para aumentar el conocimiento ambiental de los alumnos se propone potenciar el conocimiento vivencial, mantener la lengua y cultura maya y el contacto de ésta con la naturaleza y potenciar la afinidad del maestro por la temática ambiental y por la RBSK.

Multilateralismo y minilateralismo en el orden regional de Asia oriental : un análisis de las conversaciones a seis bandas

Esta memoria parte del estudio de la teoría de las Relaciones Internacionales, seguido de un análisis del regionalismo en el Este asiático, así como del multilateralismo y del minilateralismo como modus operandi en las relaciones internacionales y su desarrollo específico en el Noreste asiático, o Asia oriental. Todo ello se ha examinado con el fin de poder aprehender la dinámica internacional de la segunda crisis nuclear con Corea del Norte, así como proveer con un mayor entendimiento sobre las conversaciones a seis bandas (6PT), como ejemplo de foro de negociación minilateral creado ad hoc con el fin de buscar una solución al problema norcoreano. Hemos procedido al examen del pensamiento estratégico de los diferentes países que conforman las 6PT, así como al estudio de los intereses, acuerdos y desacuerdos de cada uno de ellos en la mesa de negociaciones con el objetivo de intentar comprender el porqué de su aparente fracaso a la hora de solucionar dicha crisis nuclear. Finalmente, hemos procedido a un estudio de la comunidad del Noreste asiático y del marco de seguridad existente en la región, así como de las perspectivas para la institucionalización de las conversaciones a seis bandas para poder comprender si, desarrollado como organización multilateral, este foro podría favorecer la estabilidad en la región, la cooperación regional y con ello una mayor integración.

Geomorphological method in the elaboration of hazard maps for flash-floods in the municipality of Jucuarán (El Salvador)

This work deals with the elaboration of flood hazard maps. These maps reflect the areas prone to floods based on the effects of Hurricane Mitch in the Municipality of Jucuarán of El Salvador. Stream channels located in the coastal range in the SE of El Salvador flow into the Pacific Ocean and generate alluvial fans. Communities often inhabit these fans can be affected by floods. The geomorphology of these stream basins is associated with small areas, steep slopes, well developed regolite and extensive deforestation. These features play a key role in the generation of flash-floods. This zone lacks comprehensive rainfall data and gauging stations. The most detailed topographic maps are on a scale of 1:25 000. Given that the scale was not sufficiently detailed, we used aerial photographs enlarged to the scale of 1:8000. The effects of Hurricane Mitch mapped on these photographs were regarded as the reference event. Flood maps have a dual purpose (1) community emergency plans, (2) regional land use planning carried out by local authorities. The geomorphological method is based on mapping the geomorphological evidence (alluvial fans, preferential stream channels, erosion and sedimentation, man-made terraces). Following the interpretation of the photographs this information was validated on the field and complemented by eyewitness reports such as the height of water and flow typology. In addition, community workshops were organized to obtain information about the evolution and the impact of the phenomena. The superimposition of this information enables us to obtain a comprehensive geomorphological map. Another aim of the study was the calculation of the peak discharge using the Manning and the paleohydraulic methods and estimates based on geomorphologic criterion. The results were compared with those obtained using the rational method. Significant differences in the order of magnitude of the calculated discharges were noted. The rational method underestimated the results owing to short and discontinuous periods of rainfall data with the result that probabilistic equations cannot be applied. The Manning method yields a wide range of results because of its dependence on the roughness coefficient. The paleohydraulic method yielded higher values than the rational and Manning methods. However, it should be pointed out that it is possible that bigger boulders could have been moved had they existed. These discharge values are lower than those obtained by the geomorphological estimates, i.e. much closer to reality. The flood hazard maps were derived from the comprehensive geomorphological map. Three categories of hazard were established (very high, high and moderate) using flood energy, water height and velocity flow deduced from geomorphological and eyewitness reports.

Human capital as a factor of growth and employment at the regional level. The case of Spain

We use statistical techniques to quantify the effects of school attainment on individual wages, participation rates and employment probabilities in Spain, and to measure the contribution of education to labour productivity at the regional level. These estimates are then combined with data on private and public expenditure on education and with information on taxes and social benefits to construct measures of the private and social returns to schooling, to explore the effects of public policies on private incentives to invest in human capital, and to analyse the long-term effects of schooling on public finances. The results are used, together with estimates of the returns to alternative assets, to draw some tentative conclusions regarding the adequacy of the aggregate investment patterns observed in the regions of Spain, and to identify changes in the design of national and EU cohesion and growth policies that may help enhance their effectiveness.

Personal redistribution and the regional allocation of public investment

How should an equity-motivated policy-marker allocate public capital (infrastructure) across regions. Should it aim at reducing interregional differences in per capita output, or at maximizing total output? Such a normative question is examined in a model where the policy-marker is exclusively concerned about personal inequality and has access to two policy instruments. (i) a personal tax-transfer system (taxation is distortionary), and (ii) the regional allocation of public investment. I show that the case for public investment as a significant instrument for interpersonal redistribution is rather weak. In the most favorable case, when the tax code is constrained to be uniform across regions, it is optimal to distort the allocation of public investment in favor of the poor regions, but only to a limited extent. The reason is that poor individuals are relatively more sensitive to public trans fers, which are maximized by allocating public investment efficiently. If! the tax code can vary across regions then the optimal policy may involve an allocation of public investment distorted in favor of the rich regions.

On the regional impact of public capital formation in Spain

The objective of this paper is to investigate, in a methodologically consistent manner, the regional effects of public capital formation and the possible existence of regional spillover effects in Spain. The empirical results are based on VAR estimates at both the aggregate and regional levels using output, employment, and private capital, as well as different measures of public capital. Empirical results suggest that public capital affects output positively at the aggregate level as well as in all but one region. For most regions, the effects of public capital installed in the region itself are important but the spillover effects induced from public capital installed elsewhere are also very important. In fact, the spillover effects account for over half of the total effects of public capital formation in Spain. Furthermore, these spillover effects have a clear geographical pattern in that they tend to be more important in the peripheral regions of the country. We also find that relative to their share of the Spanish output, the biggest beneficiaries of public capital formation are the largest regions in the country. This suggests that public capital formation has contributed to concentration of output in these regions. Finally, in terms of the effects of public capital formation on the private inputs we find that both private capital and employment are affected positively at the aggregate level as well as for most of the regions. Nevertheless, the effects on private capital seem to be larger. Also, the spillover effects are very important for private capital but not for employment. This reflects a great degree of dynamism and mobility in the capital markets as opposed to the labor markets.

Regional decomposition of CO2 emissions in the world: a cluster analysis

The purpose of this paper is to study the possible differences among countries as CO2 emitters and to examine the underlying causes of these differences. The starting point of the analysis is the Kaya identity, which allows us to break down per capita emissions in four components: an index of carbon intensity, transformation efficiency, energy intensity and social wealth. Through a cluster analysis we have identified five groups of countries with different behavior according to these four factors. One significant finding is that these groups are stable for the period analyzed. This suggests that a study based on these components can characterize quite accurately the polluting behavior of individual countries, that is to say, the classification found in the analysis could be used in other studies which look to study the behavior of countries in terms of CO2 emissions in homogeneous groups. In this sense, it supposes an advance over the traditional regional or rich-poor countries classifications .

Regional income inequalities in Europe: an updated measurement and some decomposition results

In this paper well-known summary inequality indexes are used to explore interregional income inequalities in Europe. In particular, we mainly employ Theils’population-weighted index because of its appealing properties. Two decomposition analysis are applied. First, regional inequalities are decomposed by regional subgroups (countries). Second, intertemporal inequality changes are separated into income and population changes. The main results can be summarized as follows. First, data confirm a reduction in crossregional inequality during 1982-97. Second, this reduction is basically due to real convergence among countries. Third, currently the greater part of European interregional disparities is within-country by nature, which introduce an important challenge for the European policy. Fourth, inequality changes are due mainly to income variations, population changes playing a minor role.

Knowledge, networks of cities and growth in regional urban systems

The objective of this paper is to measure the impact of different kinds of knowledge and external economies on urban growth in an intraregional context. The main hypothesis is that knowledge leads to growth, and that this knowledge is related to the existence of agglomeration and network externalities in cities. We develop a three-tage methodology: first, we measure the amount and growth of knowledge in cities using the OCDE (2003) classification and employment data; second, we identify the spatial structure of the area of analysis (networks of cities); third, we combine the Glaeser - Henderson - De Lucio models with spatial econometric specifications in order to contrast the existence of spatially static (agglomeration) and spatially dynamic (network) external economies in an urban growth model. Results suggest that higher growth rates are associated to higher levels of technology and knowledge. The growth of the different kinds of knowledge is related to local and spatial factors (agglomeration and network externalities) and each knowledge intensity shows a particular response to these factors. These results have implications for policy design, since we can forecast and intervene on local knowledge development paths.

La Inversión española en el extranjero (1993-2005). Origen regional: análisis y evolución

A nivel mundial, en las últimas tres décadas, la inversión directa ha experimentado un desarrollo espectacular. Los datos de la UNCTAD muestran como, entre 1970 y 2005, los flujos de inversión emitida crecieron más de un quinientos por cien. A pesar que, para el conjunto del periodo estos incrementos inversión fueron continuados, hay que diferenciar cuatro etapas. Hasta principios de los ochenta, el volumen no era excesivamente elevado, pero las tasas de incremento mostraban una tendencia cada vez mayor en el desarrollo de la inversión a nivel mundial. Entre mediados de los ochenta y noventa, los flujos empezaron a crecer de forma más notable y sostenida. El boom inversor se produjo, sobretodo, a partir de los cuatro últimos años del siglo veinte, cuando la inversión creció a un ritmo espectacular; con tasas de incremento anual que en algunos años (como el de 1999) rozaron el sesenta por ciento. Tras el inicio del siglo XXI, la inversión directa se ralentizó. Entre los años 2001 y 2005 las salidas de capital disminuyeron y, aunque se mantuvieron en niveles ciertamente altos en comparación con el conjunto del periodo, fueron sensiblemente más bajos que los registrados a finales de la década de los noventa. El incremento general de este tipo de movimientos internacionales de capital, iniciado, sobretodo, a partir de la década de los ochenta y eclosionado a mediados de los noventa tuvo origen en un contexto de progresiva y paulatina liberalización de las relaciones económicas a nivel mundial; en transformaciones institucionales de gran calado en prácticamente todas las economías del mundo, y en un contexto de fuerte crecimiento económico impulsado, en gran parte, por el desarrollo tecnológico de la llamada "nueva economía".

Guía para el diseño e implementación de un master en accesibilidad universal. La aplicación del diseño para todos en entornos, productos y servicios

Esta Guía nace con la intención de impulsar en esta situación poco favorable el desarrollo del mencionado curso de postgrado en la universidad española. En ese sentido, pretende ser un recurso a utilizar por el profesorado universitario y el grupo de expertos en accesibilidad que constituya el futuro equipo docente de esta iniciativa formativa, como punto de partida para el necesario proceso de concreción curricular que tendrán que realizar. Queremos destacar aquí que esta guía no se concibe, por tanto, como el programa de un Master en accesibilidad Universal, aunque incluye a modo de ejemplo una propuesta concreta, sino como un conjunto de recursos a utilizar para elaborarlo, respetando así el principio de autonomía universitaria y docente en el que creemos firmemente.

Inversión en infraestructuras, crecimiento y convergencia regional

This paper presents estimates of the contribution of infrastructure investment to the growth of output and employment in Spain and its regions and investigates the impact of this factor on the process of regional convergence in income per capita during the period 1965-2004.

Trans-Atlantic Pedagogy for Teaching Pre-Service Teachers ICT: Bringing forward cultural issues

Projecte de recerca elaborat a partir d’una estada a la Universitat de Toronto, Canadà, des d’octubre del 2006 a febrer del 2007. El projecte Barchito és un projecte Interrnacional que va involucrar tres universitats: La Universitat Autònoma de Barcelona, la Universitat de Toronto (Canadà) i la Universitat de Roosevelt (USA). El seu objectiu principal era posar en contacte estudiants de les tres universitats (de tres cursos diferents) per discutir al voltant de temes com ara l'ensenyament/aprenentatge i elements culturals de cada país. Aquest projecte presenta la natura de l'experiència des de la visió dels participants: alumnat i professorat. Superant diferències inicials de llengua, els participants van aprendre d'altra cultura, van aprendre sobre altres maneres d'ensenyar i van aprendre, en definitiva, sobre ells mateixos. L'eina d'aprenentatge col.laboratiu els va ajudar a sobrepassar el context immediat, emprant per això, l'eina tecnològica anomenada: Knowledge Forum.

El Orden regional de Asia oriental en materia de seguridad

El trabajo analiza los procesos de gestación y evolución del orden regional de Asia oriental en materia de seguridad, así como la estructura normativa del mismo. En estos procesos las iniciativas bilaterales de los Estados tradicionalmente han jugado un papel determinante. Las últimas dos décadas, no obstante, han sido testigo del creciente peso de otros actores no estatales en el marco del llamado second track y del impulso de iniciativas multilaterales. En cuanto a la estructura de este orden, por otra parte, ésta se compone de unos principios y normas constitucionales y de unas instituciones fundamentales que delimitan un orden diferente de y compatible con el orden internacional actual.
