La incidencia de la actualización del tratado de amistad India-Bután 2007 en las orientaciones en materia de política exterior de Bután. 2007-2014

El interés de este estudio de caso es analizar la incidencia de la actualización del Tratado de Amistad entre India y Bután firmado en 2007 en las disposiciones de política exterior de Bután en el periodo 2007-2014. Este trabajo se enmarca en los conceptos de identidad nacional, tomadores de decisiones, proceso de toma de decisión y análisis de política exterior, a partir de los cuales se pretende comprobar que el tratado de 2007 tuvo principalmente un efecto cristalizador en la política exterior de Bután, manifestado de manera significativa en materia de cooperación internacional, moderada en materia de representación política internacional y muy modesta en materia de apertura económica y comercial.

Brasil: elementos básicos para entender a la superpotencia sudamericana (Tema Central)

El presente estudio apunta a proveerle al lector con elementos para responder a un conjunto de preguntas relevantes para el diseño de una política bilateral Ecuador-Brasil coherente, entre otras: ¿Qué explica el surgimiento de Brasil como una potencia económica global?, ¿Cómo ese exitoso desarrollo económico –y social– ha influido en la política internacional de esta nación?, ¿Cómo podría afectar a Ecuador la creciente influencia internacional de Brasil en algunos de los organismos centrales para la toma de decisiones económicas mundiales, tales como el Grupo de los 20 (G-20), la Organización Mundial del Comercio (OMC) y el Fondo Monetario Internacional (FMI)? A continuación mostraré que esas preguntas no solo se relacionan entre sí, sino que, de hecho, tienen una respuesta común: la economía política del desarrollo brasileño tanto histórico como de los últimos veinte años explica su emergencia económica, los notables cambios en su política exterior en los noventa y la presente década, y los límites y oportunidades de la proyección internacional brasileña en el presente y el futuro más o menos inmediato.

Relaciones comerciales Ecuador-Brasil: un tablero sin alfiles (Tema Central)

Este artículo analiza la relación comercial de Ecuador con Brasil, la cual ha vivido prácticamente tres años de inmovilidad o “tiempo de reposo”, como lo calificó la excanciller ecuatoriana, María Isabel Salvador, el 16 de octubre de 2008, luego que el presidente Rafael Correa expulsara, a través de Decreto Ejecutivo, a la constructora brasileña Norberto Odebrecht.3 La justificación para esta acción fue que aproximadamente a un año de la terminación de los trabajos de Odebrecht en la central hidroeléctrica San Francisco se produjo una serie de daños en la misma, con la consecuente crisis energética. El gobierno del Ecuador responsabilizó al consorcio brasileño de una deficiente labor técnica en la construcción de la central hidroeléctrica lo que ocasionó su paralización por varios meses y la consecuente interrupción de la producción y suministro de energía eléctrica en el territorio ecuatoriano.

The Mystery of Privity: Grand Trunk Railway Company of Canada v Robinson (1915)

This article examines a little known decision of the Judicial Committee of the Privy Council: Grand Trunk Railway Company of Canada v Robinson (1915). The examination is historical and it provides a different insight into the understanding of privity of contract, a doctrine central to contract law. The examination reveals a process of trans-Atlantic legal migration in which English law was applied to resolve an Ontario case. The nature of the resolution is surprising because it appears to conflict with the better known decision of the House of Lords, Dunlop Pneumatic Tyre Company, Limited v Selfridge and Company, Limited, which a similarly constituted panel delivered in the same week. This article argues that there was a greater malleability in the resolution of cases concerned with privity than was thought to have existed. It is also argued that the power of Canadian railway capitalism is a significant factor in understanding the legal resolution of the case. Finally, it the article considers the use of English and American precedents relevant to the case. The application of English precedents to the case led to a resolution not entirely befitting Canadian conditions.

The impact of outward investments on parent company's employment and skill composition

This paper investigates the impact of outward foreign direct investment (FDI) by Italian multinationals on their total employment and skill composition. Specifically, by comparing data on 108 Italian manufacturing firms that became multinational (for the first time) in the period 1998–2004 with a counterfactual group of 2500 national firms that remained national in the same period, we provide descriptive and econometric evidence that the internationalisation of production activities did not reduce domestic employment in the parent companies neither for investments in developed or developing countries. As far as the skill composition is concerned, results reveal that only firms investing in Central and Eastern European countries experience some skill upgrading relative to firms that remained national.

Nitric oxide regulation of the central aortae of the toad Bufo marinus occurs independently of the endothelium

Nitric oxide (NO) signalling pathways were examined in the lateral aortae and dorsal aorta of the cane toad Bufo marinus. NADPH diaphorase histochemistry and nitric oxide synthase (NOS) immunohistochemistry found no evidence for endothelial NOS in the endothelium of toad aortae, but it could be readily demonstrated in rat aorta that was used as a control. Immunohistochemistry using a specific neural NOS antibody showed the presence of neural NOS immunoreactivity in the perivascular nerves of the aortae. The anatomical data was supported by in vitro organ bath physiology, which demonstrated that the vasodilation mediated by applied acetylcholine (10^-5 mol l^-1) was not dependent on the presence of the vascular endothelium; however, it was significantly reduced in the presence of a neural NOS inhibitor, vinyl-L-NIO (10-4 mol l^-1). In addition, atropine (10^-6 mol l^-1) (a muscarinic receptor inhibitor), L-NNA (10^-4 mol l^-1) (a NOS inhibitor) and ODQ (10^-5 mol l^-1) (an inhibitor of soluble guanylyl cyclase) abolished the vasodilatory effect of applied acetylcholine. In conclusion, we propose that an endothelial NO system is absent in toad aortae and that NO generated by neural NOS in perivascular nerves mediates vasodilation.

Paleoenvironmental analysis of a late-holocene subfossil Coleopteran fauna from Starks, Maine

The Sandy River in central Maine Is flanked along much of its length by low terraces. Approximately 100 kg of sediment from one terrace in Starks, Somerset County, Maine was wet-sieved in the field. Over 1100 subfossil Coleoptera were recovered representing 53 individual species of a total of 99 taxa. Wood associated with the fauna is 2000 +/-80 14C Yr in age (1-16,038). The fauna is dominated by species characteristic of habitats apparent in modern central Maine. The subfossil assemblage is indicative of a wide vartety of environments including open ground (e.g., Harpalus pensylvanicus), dense forest (e.g., pterostichus honestus), aquatic environments (e.g., Gyrinus, Helophorus), riparian environments with sand and gravel substrates (e.g., Bembidion inaequale, Schizogenius lineolatus), and moist, organic-rich terrestrial environments (e.g., Micropeplus sculptus). The ecological requirements for each taxon permit an environmental reconstruction suggesting an area vegetationally, climatically, and ecologically similar to that of the Sandy River today. The lowest terraces apparently represent the modern-day floodplain of the Sandy River. An average sedimentation rate of l.00 to 1.04 mm per year has been inferred based on radiocarbon dates here and elsewhere on the Sandy River. The Coleopteran fauna suggests that sand and gravel were distinctly abundant, and that the aggradation of point bars, as seen today, contributed to the flood history. Lateral bank erosion of the modern Sandy River accelerated after the State of Maine mandated cessation of bar removal in 1975: flood severity has dramatically increased since that time. Implications suggest that mining of the bars may be necessary to minimize future flooding problems.

Caminhos que estruturam cidades: redes técnicas de transporte sobre trilhos e a conformação intra-urbana de Natal

The railroad, from 1870 and on, becomes an usual complaining in the press s and politician elite s speeches, especially because of Natal s geographic isolation. The implantation of two railroads in the capital territory Estrada de Ferro de Natal a Nova Cruz, afterwards part of Great Western Railway Company network, and Estrada de Ferro Central do Rio Grande do Norte had serious implications in the urban environment. While railroad s structures were already consolidated, other transportation mechanisms were being implanted in the first decades of the 20th century, such as trams lines, which, by the way, was a transport modal that also used rails as a dislocation meaning. Considering these questions, we may ask: how come railroads and tramways demands, roads and buildings had influenced the internal organization of Natal? We work with the general hypothesis that the influence of technical networks, composed by tramways and railroads, over Natal s urban space happened in a diversified way, sometimes consolidating social aspects in certain areas, sometimes improving the occupation of others. The impact over the city s territory also happens in a diversified way between the buildings/railroad s complexes and the pathways. The different scale of the train in comparison to the trams velocity, size, noise level, flow, among others is also a cause to the different consequences in urban environment. The main objective of this work is to understand the role of circulation technical networks in the construction process of urban space in Natal, as a way to contribute to the urban historiography about the subject. The time frame adopted, between 1881 and 1937, marks the time path of railroads and tramways in Rio Grande do Norte: 1881 is the year of railroad s first section inauguration from Natal to São José do Mipibu as well of the railroad complex in the Republic Square in Natal; the year of 1937 marks the beginning of tramways declination process in the city. At this time railroads and tramways had to face more intensively the competition of motor vehicles. The theory reference adopted is based on concepts and analysis of authors, such as Flávio Villaça and Roberto Lobato Corrêa references to the concepts of urban structure , localization and accessibility and Gabriel Dupuy to explain the concept of urban technical networks . These references reveal the conflict of different realities in the urban universe interests and values which is an important factor about the construction of urban space. The information sources used were from two distinctive natures: primary, journals of the time studied and official government reports, and secondary, based on other works about the subject. It was also used by this study iconographic source, especially images from the data base of the research group História da Cidade, do Território e do Urbanismo .

Custo de energia elétrica em cultura do feijoeiro irrigado por pivô central, afetado pelo manejo da irrigação e sistemas de cultivo

O objetivo deste trabalho foi analisar o consumo e o custo de energia elétrica em cultura do feijoeiro irrigado por pivô central, cultivar IAC-Carioca, submetida a dois manejos de irrigação: TENS - tensiometria; TCA - balanço hídrico-climatológico, baseado no tanque Classe A; e dois sistemas de cultivo em Latossolo Vermelho: PD - plantio direto; PC - plantio convencional, no ano de 2002. A pesquisa foi desenvolvida na Área Demonstrativa e Experimental de Irrigação - ADEI da FCAV/UNESP, Câmpus de Jaboticabal - SP. O consumo de energia elétrica do sistema de irrigação foi monitorado, e seu custo, analisado para dois grupos tarifários: A e B, sendo os preços do kWh dos sistemas tarifários de energia elétrica obtidos na CPFL (Companhia Paulista de Força e Luz). Os tratamentos em que o manejo da irrigação foi realizado pelo método do tanque Classe A, ocasionaram os maiores consumos e custos de energia elétrica, em relação aos tratamentos em que o manejo foi realizado por tensiometria; entre os sistemas de plantio, não foram observadas diferenças. A tarifa Horo-Sazonal (verde e/ou azul), com desconto, foi a melhor opção para os quatro tratamentos.

The Redistribution of Property Rights, Corporate Governance and Company Restructuring after Privatisation"

The project covered the main issues of privatisation, corporate governance and company restructuring after privatisation in Hungary and in the Russian Republic, together with a summary of the broader picture of company-level changes in Central and Eastern Europe, discussing the issues of micro-financial restructuring in the Czech Republic, Hungary, Poland and Slovakia. The two countries selected as the focus of research can be regarded as the two most widely differing cases of the economic transformation in Central and Eastern Europe. Hungary began its transition very early in 1989, while Russia was very late in doing so. Hungary first implemented a series of institutional and systemic reforms before stabilising its public finances, while Russia has struggled with financial stabilisation for years without great success. Company restructuring and the introduction of new forms of governance only began in Russia in the mid-1990s. Hungary opted for "traditional" western methods of privatisation and invited a large amount of foreign direct investment (FDI) while in Russia the bulk of state-owned property was privatised either by free distribution or by a strange blend of ESOP-MBO schemes. FDI in Russia remained modest because of the high risk and uncertainty surrounding economic transactions there. Hungary was a forerunner in privatising public utilities, while Russia has moved cautiously in this area. The group's studies show that the Hungarian economy is now over the "transformation recession" and its economic success is largely due to its successful privatisation and to the dominant participation of foreign investors in company take-overs and in the restructuring process. The study of Russia provides a comprehensive account of the main factors in the so-far modest results in Russian privatisation and economic transformation.

Experimental Determination of Salinity, Temperature, Growth, and Metabolic Effects on Shell Isotope Chemistry of Mytilus edulis Collected from Maine and Greenland

To study the effects of temperature, salinity, and life processes (growth rates, size, metabolic effects, and physiological/ genetic effects) on newly precipitated bivalve carbonate, we quantified shell isotopic chemistry of adult and juvenile animals of the intertidal bivalve Mytilus edulis (Blue mussel) collected alive from western Greenland and the central Gulf of Maine and cultured them under controlled conditions. Data for juvenile and adult M. edulis bivalves cultured in this study, and previously by Wanamaker et al. (2006), yielded statistically identical paleotemperature relationships. On the basis of these experiments we have developed a species-specific paleotemperature equation for the bivalve M. edulis [T degrees C = 16.28 (+/- 0.10) -4.57 (+/- 0.15) {delta(18)O(c) VPBD - delta(18)O(w) VSMOW} + 0.06 (+/- 0.06) {delta(18)O(c) VPBD - delta(18)O(w) VSMOW}(2); r(2) = 0.99; N = 323; p < 0.0001]. Compared to the Kim and O'Neil (1997) inorganic calcite equation, M. edulis deposits its shell in isotope equilibrium (delta(18)O(calcite)) with ambient water. Carbon isotopes (delta(13)C(calcite)) from sampled shells were substantially more negative than predicted values, indicating an uptake of metabolic carbon into shell carbonate, and delta(13)C(calcite) disequilibrium increased with increasing salinity. Sampled shells of M. edulis showed no significant trends in delta(18)O(calcite) based on size, cultured growth rates, or geographic collection location, suggesting that vital effects do not affect delta(18)O(calcite) in M. edulis. The broad modern and paleogeographic distribution of this bivalve, its abundance during the Holocene, and the lack of an intraspecies physiologic isotope effect demonstrated here make it an ideal nearshore paleoceanographic proxy throughout much of the North Atlantic Ocean.

Response of a First-Order Stream in Maine to Short-Term In-Stream Acidification

An experimental short-term acidification with HCl at a first-order stream in central Maine, USA was used to study processes controlling the changes in stream chemistry and to assess the ability of stream substrate to buffer pH. The streambed exerted a strong buffering capacity against pH change by ion exchange during the 6-hour acidification. Streambed substrates had substantial cation and anion exchange capacity in the pH range of 4.1 to 6.5. The ion exchange for cations and SO42- were rapid and reversible. The speed of release of cations from stream substrates was Na1+ > Ca2+ > Mg2+ > Aln+ > Be2+, perhaps relating to charge density of these cations. Ca2+ desorption dominated neutralisation of excess H+ for the first 2 hr. As the reservoir of exchangeable Ca diminished, desorption land possibly dissolution) of Al3+ became the dominant neutralising mechanism. The exchangeable land possibly soluble) reservoir of Al was not depleted during the 6-hour acidification. Sulphate adsorption during the acidification reduced the concentration of SO42- in stream water by as much as 20 mu eq L-1 (from 70 mu eq L-1). Desorption of SO42- and adsorption of base cat ions after the artificial acidification resulted in a prolongation of the pH depression. The streambed had the capacity to buffer stream water chemistry significantly during an acidifying event affecting the entire upstream catchment.
