Inserción del Ecuador a la Cuenca del Pacífico. ¿Qué debemos esperar del nuevo gobierno? (Tema Central)

La autora sostiene que, a diferencia de los actores asiáticos que se mueven dentro de las políticas definidas por los organismos regionales, los organismos multilaterales latinoamericanos no son tan eficientes para cumplir su rol de interlocutores con el Asia Pacífico. Al diseñar sus políticas exteriores hacia los países asiáticos, Ecuador no debe obnubilarse por la extensión geográfica, la magnitud de su población o las economías de escala. Las oportunidades están en la posibilidad de ofrecer un mercado ampliado hacia la región andina.

¿Integración frente al unilateralismo? La economía política del ALCA (Tema Central)

Romero sostiene que la dinámica del ALCA parece seguir un curso inexorable, en medio de la contemplación de los responsables de las economías latinoamericanas. Salvo contadas excepciones, no existe un debate amplio sobre el proceso, ni una evaluación clara de sus implicaciones. El análisis de las posiciones predominantes en el gobierno y en el congreso norteamericano, expresadas en la discusión de la ""vía rápida"", señalan una clara tendencia hacia el unilateralismo, que puede vaciar de cualquier interés al ALCA. Según el autor, es preciso analizar adecuadamente esas perspectivas, revalorizando los esquemas de integración en América Latina y volver a situar al comercio en el marco de la política de desarrollo.

Criterios de interpretación en la nueva Constitución de Bolivia. Voluntad del constituyente vs. jurisprudencia de la Corte Interamericana de Derechos Humanos (Tema Central)

En este artículo se analizará la posibilidad del Tribunal Constitucional Plurinacional de aplicar, como criterio de interpretación, la jurisprudencia de la Corte Interamericana de Derechos Humanos, de forma preferente a la voluntad del constituyente boliviano como otro criterio de interpretación dispuesto expresamente, a ese efecto se tendrá en cuenta el rol de la interpretación constitucional y su relación con las normas internacionales de derechos humanos, el análisis de la posición jurídica de la jurisprudencia de la Corte Interamericana de Derechos Humanos en el sistema jurídico boliviano, el efecto de la jurisprudencia de la Corte en la protección de derechos humanos, y el análisis de esta jurisprudencia en relación con la voluntad del constituyente como criterios de interpretación.

Una agenda internacional imBRICada: los nuevos caminos y desafíos de la política externa brasileña en el siglo XXI (Tema Central)

Este ensayo, de carácter analítico-descriptivo, pretende transitar entre las grandes líneas de la política exterior brasileña a lo largo de la primera década del siglo XXI, más específicamente durante los dos mandatos de Luiz Inácio Lula Da Silva (2003-2006 y 2007-2010), a fin de identificar en qué medida la agenda internacional brasileña fue afectada desde su categorización como potencia emergente bajo el acrónimo de BRIC (Brasil, Rusia, India y China) en el año 2003. El análisis parte de la premisa de que la política exterior brasileña, a lo largo de la primera década del siglo XXI, está más que nunca, imBRICada. Más allá de un simple juego de palabras, im“BRIC”ar significa dejar en evidencia la forma compleja en la que interactúan las diversas prioridades de la agenda internacional de un país emergente como Brasil, a veces convergiendo, a veces discrepando.

Brasil y la integración sudamericana: algunas claves de interpretación (Tema Central)

El propósito del presente artículo es reflexionar sobre el papel de Brasil en el actual proceso de integración sudamericana. Nuestra tesis es que dicho rol es a la vez causa y consecuencia de dos realidades a las que se refieren el exsecretario de Estado Norteamericano y la excandidata del Partido de los Trabajadores y actual presidenta de Brasil en los epígrafes anteriores, es decir, que Brasil se está convirtiendo en una potencia y que una de las claves de eso es el proceso de internacionalización de las empresas que operan en su territorio. Nos interesa plantear la tesis de que la convergencia de una serie de factores a partir de mediados de la década de 1990 es lo que posibilita que Brasil se haya convertido en el pivote del proceso de integración que, buscando la construcción de un espacio sudamericano integrado como objetivo estratégico, se despliega en varios ámbitos: económico, de infraestructura, político e incluso militar.

Gobernanza Ambiental en América Latina: hacia una agenda de investigación integradora (Tema Central)

América Latina juega un papel importante en relación con la Gobernanza Ambiental. El conocimiento generado por estudios empíricos y teóricos sobre los desafíos ambientales del presente pueden apoyar los renovados esfuerzos de la región por alcanzar un uso de los recursos naturales que sea equitativo y sustentable. A pesar de que los vínculos entre las dimensiones social y ambiental han sido explorados por la academia desde los años noventa, las nuevas tendencias de la Gobernanza Ambiental en América Latina requieren una aproximación analítica comprehensiva. Los autores argumentan que, a fin de potenciar las “perspectivas latinoamericanas” para la solución de los dilemas socioambientales, algunas corrientes de investigación deben juntarse en marcos analíticos integradores que puedan generar complejas preguntas relacionadas con las interacciones a múltiples niveles entre Estado, sociedad civil y actores de mercado.

El control de convencionalidad y la protección del derecho a la propiedad privada a partir de la sentencia del caso Salvador Chiriboga vs. Ecuador (Tema Central)

The contents of this article analyze the right to private property after the decision of the Inter-American Court of Human Rights in the case “Salvador Chiriboga vs. Ecuador”. The author´s concern is the fact that this case represents the most expensive sentence inside the Inter-American protection system due to the violation of the right to private property (art. 21.2 AC); judicial guarantees (art. 8.1 AC) and judicial protection (art. 25.1 CA). This subject has special relevance since Ecuador is facing a judicial reform process and it is necessary to consider that the diffusion of this decision among judges could prevent the commission of the same mistakes; specially, those related to denial of justice as it occurred in the present case study.

La heterogeneidad de la imagen de China en la política exterior latinoamericana. Perspectivas para la concertación de políticas (Tema Central)

The text shows the heterogeneous views of various Latin American countries, like Mexico, Brazil, Argentina, Chile, Colombia and Venezuela, in terms of their analyses of and studies about foreign policy. This paper aims to make clear the different images that China generates as a rising power in the world economy, particularly as a major trade partner of these countries. The goal of this article is to provide elements for analysis about policy coordination vis-àvis China. The central argument states that there should be coordination between regional integration strategies and foreign policies in relation to China. However, these heterogeneous visions can work against that goal as well.

Linking Canadian Harvested Juvenile American Black Ducks to Their Natal Areas Using Stable Isotope (δD, δ13C, and δ15N) Methods

Understanding source-sink dynamics of game birds is essential to harvest and habitat management but acquiring this information is often logistically and financially challenging using traditional methods of population surveys and banding studies. This is especially true for species such as the American Black Duck (Anas rubripes), which have low breeding densities and extensive breeding ranges that necessitate extensive surveys and banding programs across eastern North America. Despite this effort, the contribution of birds fledged from various landscapes and habitat types within specific breeding ranges to regional harvest is largely unknown but remains an important consideration in adaptive harvest management and targeted habitat conservation strategies. We investigated if stable isotope (δD, δ13C, δ15N) could augment our present understanding of connectivity between breeding and harvest areas and so provide information relevant to the two main management strategies for black ducks, harvest and habitat management. We obtained specimens from 200 hatch-year Black Duck wings submitted to the Canadian Wildlife Service Species Composition Survey. Samples were obtained from birds harvested in Western, Central, and Eastern breeding/harvest subregions to provide a sample representative of the range and harvest rate of birds harvested in Canada. We sampled only hatch-year birds to provide an unambiguous and direct link between production and harvest areas. Marine origins were assigned to 12%, 7%, and 5% of birds harvested in the Eastern, Central, and Western subregions, respectively. In contrast, 32%, 9%, and 5% of birds were assigned, respectively, to agricultural origins. All remaining birds were assigned to nonagricultural origins. We portrayed probability of origin using a combination of Bayesian statistical and GIS methods. Placement of most eastern birds was western Nova Scotia, eastern New Brunswick, Prince Edward Island, and southern Newfoundland. Agricultural birds from the Central region were consistent with the Saguenay region of Québec and the eastern claybelt with nonagricultural birds originating in the boreal. Western nonagricultural birds were associated with broad boreal origins from southern James Bay to Lake of the Woods and east to Cochrane, Ontario. Our work shows that the geographic origins, landscape, and habitat associations of hatch-year Black Ducks can be inferred using this technique and we recommend that a broad-scale isotopic study using a large sample of Canadian and US harvested birds be implemented to provide a continental perspective of source-sink population dynamics.

Dispersion Experiments in Central London: The 2007 DAPPLE project

In the event of a release of toxic gas in the center of London, the emergency services would need to determine quickly the extent of the area contaminated. The transport of pollutants by turbulent flow within the complex street and building architecture of cities is not straightforward, and we might wonder whether it is at all possible to make a scientifically-reasoned decision. Here we describe recent progress from a major UK project, ‘Dispersion of Air Pollution and its Penetration into the Local Environment’ (DAPPLE, www.dapple.org.uk). In DAPPLE, we focus on the movement of airborne pollutants in cities by developing a greater understanding of atmospheric flow and dispersion within urban street networks. In particular, we carried out full-scale dispersion experiments in central London (UK) during 2003, 2004, 2007, and 2008 to address the extent of the dispersion of tracers following their release at street level. These measurements complemented previous studies because (i) our focus was on dispersion within the first kilometer from the source, when most of the material was expected to remain within the street network rather than being mixed into the boundary layer aloft, (ii) measurements were made under a wide variety of meteorological conditions, and (iii) central London represents a European, rather than North American, city geometry. Interpretation of the results from the full-scale experiments was supported by extensive numerical and wind tunnel modeling, which allowed more detailed analysis under idealized and controlled conditions. In this article, we review the full-scale DAPPLE methodologies and show early results from the analysis of the 2007 field campaign data.

Seasonal pattern of regional carbon balance in the central Rocky Mountains from surface and airborne measurements

[1] High-elevation forests represent a large fraction of potential carbon uptake in North America, but this uptake is not well constrained by observations. Additionally, forests in the Rocky Mountains have recently been severely damaged by drought, fire, and insect outbreaks, which have been quantified at local scales but not assessed in terms of carbon uptake at regional scales. The Airborne Carbon in the Mountains Experiment was carried out in 2007 partly to assess carbon uptake in western U.S. mountain ecosystems. The magnitude and seasonal change of carbon uptake were quantified by (1) paired upwind-downwind airborne CO2 observations applied in a boundary layer budget, (2) a spatially explicit ecosystem model constrained using remote sensing and flux tower observations, and (3) a downscaled global tracer transport inversion. Top-down approaches had mean carbon uptake equivalent to flux tower observations at a subalpine forest, while the ecosystem model showed less. The techniques disagreed on temporal evolution. Regional carbon uptake was greatest in the early summer immediately following snowmelt and tended to lessen as the region experienced dry summer conditions. This reduction was more pronounced in the airborne budget and inversion than in flux tower or upscaling, possibly related to lower snow water availability in forests sampled by the aircraft, which were lower in elevation than the tower site. Changes in vegetative greenness associated with insect outbreaks were detected using satellite reflectance observations, but impacts on regional carbon cycling were unclear, highlighting the need to better quantify this emerging disturbance effect on montane forest carbon cycling.

‘New World and Old Europe: American Screen Images of Britain and France‘

Contrary to the dearly held belief by Britons that among the nations of the world, they are the favourites of the Americans, Holliwood movies show that even today, judging by the accents of "baddies", the English incarnate the arch-enemy. French villains come a close second. Britain and France are the reactionary, corrupt "old Europe" from whom the Americans tried to cut away ever since 1775, and it is actually the Central-East European countries who as "new Europe" enjoy greater popularity as bearers of hope.
