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.

¿Eran cuidadanos los afrodescendientes libres en las sociedades esclavistas?: Cuba, Brasil y Estados Unidos en el siglo XIX (Estudios)

Se analiza el tema del estatus de los afrodescendientes libres en las sociedades esclavistas más pobladas de América, desde el punto de vista de los derechos políticos y sociales de súbditos y ciudadanos. Con la carta de libertad, los antiguos esclavos y sus descendientes libres adquirieron teóricamente los mismos derechos y obligaciones que la población blanca eurodescendiente. Sin embargo, por razones de “seguridad pública” y de “mantención del orden establecido”, en la práctica, se establecieron restricciones y privilegios para mantener la distancia social entre blancos y afrodescendientes. Desde una perspectiva comparada se estudian Brasil, Cuba y los Estados Unidos, las tres sociedades esclavistas más notorias en América durante el siglo XIX, y se examina este proceso tomando como objetos de análisis los derechos de libre movimiento, el acceso a la enseñanza superior, el sufragio y la propiedad.

Portuñol salvaje: arte licuafronteras y tensiones contemporáneas (Dossier: Literaturas de la integración, el Sur y su diversidad)

Pensar, escribir, cantar, vivir entre idiomas. Producir conocimiento desde zonas limítrofes, desde lugares y desde memorias y saberes múltiples. En este texto se busca indagar los sentidos que se insinúan en un conjunto de prácticas artísticas (literarias, visuales, musicales) que se gestan en torno a lo que se ha bautizado como portuñol salvaje. Para ello, luego de una caracterización del portuñol, se busca evidenciar la recurrencia de un gesto artístico que deviene producción de conocimiento. Se plantea que, consideradas en conjunto y a partir del contexto geocultural en el que surgen, dichas prácticas constituyen un fecundo aporte para comprender una serie de aspectos sociales, culturales, económicos y políticos de nuestras sociedades.

Los orígenes jurídicos del sistema político imperial español y su influencia en las Américas (Estudios)

Este ensayo examina la naturaleza jurídica y política del imperio español en América y sus orígenes medievales. Con el fin de ofrecer un nuevo enfoque para estudiar la relación entre España y sus posesiones americanas, este trabajo propone una revisión de la tradición jurídica española. El estudio de la evolución de los conceptos de soberanía, representación y jurisdicción permite dilucidar los elementos constitutivos de las relaciones entre las diversas entidades políticas como mecanismo de comprensión del desarrollo de la cultura política de América Latina. De acuerdo a las características del sistema jurídico político en la época virreinal, la dispensación de la justicia y la práctica judicial constituyeron el eje de las relaciones entre la autoridad imperial y sus periferias. El artículo sostiene que la práctica judicial estuvo llena de sentido político y se convirtió en un medio de inclusión y representación.

En busca de tinterillos. Intermediarios en el mundo indígena ecuatoriano durante el siglo XX (Debates)

Este artículo aborda el papel de los abogados semiprofesionales, conocidos como tinterillos, en las comunidades indígenas de la sierra ecuatoriana, a partir de mediados del siglo XIX, quienes adquirieron una presencia aparentemente ubicua en las comunidades rurales del Ecuador. Muchas veces los tinterillos fueron parte de las élites locales con algo de educación. Inspiraban respeto entre los indígenas (quienes, en su mayoría, eran analfabetos) debido a su habilidad a manejar documentos escritos. Estos intermediarios comúnmente explotaron su posición privilegiada para su propio beneficio económico, social y político. Sin embargo, los indígenas llegaron a depender del apoyo de los tinterillos para denunciar ante el gobierno los abusos de los terratenientes. En ocasiones, en lugar de sentirse impotentes o víctimas, los indígenas aprendieron a negociar sus relaciones con esos intermediarios para su beneficio. El estudio de los tinterillos permite examinar las relaciones de poder que se negociaron entre diferentes culturas y a través de profundas divisiones de clase.

Entre el cine boliviano de los años sesenta y la novela indigenista: un caso de transculturación estética andina (Estudios)

El artículo es un ejercicio de historia cultural que explora la conflictiva relación entre la obra cinematográfica del realizador boliviano Jorge Sanjinés y del grupo Ukamau, desarrollada en los años setenta, y la novela indigenista andina escrita varias décadas antes, en relación a la problemática de la representación del indígena y de su lugar en la comunidad nacional. En esta perspectiva, el trabajo analiza la compleja interacción entre cultura letrada, cinematografía y construcción nacional en Bolivia. El estudio considera el contexto histórico modernizador emprendido por la revolución de 1952 y los ulteriores momentos de este proceso político y social fundamental de ese país andino, situando los desafíos estéticos y políticos que la obra de Jorge Sanjinés debió enfrentar.

La excepción argentina. Construcción del Estado y de la Iglesia en el siglo XIX (Estudios)

Around 1930, Argentina was one of the richest, most dynamic and modern countries in Latin America and, at the same time, the only one on the continent that had not separated Church from State. This observation can be summed up and singled out among the many hypotheses during the last decades that have permitted the questioning of the most schematic, linear and teleological reports concerning the secularization process. This article puts forward a report concerning the double process of state and ecclesiastical construction in Argentina in the Nineteenth Century. Its purpose is to suggest keys for understanding said report that permit the comprehension of special features concerning the type of laicism that Argentina adopted at the beginning of the Twentieth Century.

Las implicaciones políticas de la relación China-América Latina: el Consenso Asiático como red de poder global y el caso brasileño (Tema Central)

This paper analyzes the People’s Republic of China economic and political ascendance in the 21st century, focusing on the evolution of its sui géneris economic development model and its significance for the relationship between China and the developing countries of the peripheral ‘Global South.’ The objective of this article is to analyze the relationship between China and Latin America in the 21st century, characterizing it as a new Center-periphery global power network based on trade and investment, which is often referred to as the ‘Asian Consensus’. The article will give special attention to the Brazilian case.

Incorporating Legacy Soil pH Databases into Digital Soil Maps

Soil data and reliable soil maps are imperative for environmental management. conservation and policy. Data from historical point surveys, e.g. experiment site data and farmers fields can serve this purpose. However, legacy soil information is not necessarily collected for spatial analysis and mapping such that the data may not have immediately useful geo-references. Methods are required to utilise these historical soil databases so that we can produce quantitative maps of soil propel-ties to assess spatial and temporal trends but also to assess where future sampling is required. This paper discusses two such databases: the Representative Soil Sampling Scheme which has monitored the agricultural soil in England and Wales from 1969 to 2003 (between 400 and 900 bulked soil samples were taken annually from different agricultural fields); and the former State Chemistry Laboratory, Victoria, Australia where between 1973 and 1994 approximately 80,000 soil samples were submitted for analysis by farmers. Previous statistical analyses have been performed using administrative regions (with sharp boundaries) for both databases, which are largely unrelated to natural features. For a more detailed spatial analysis that call be linked to climate and terrain attributes, gradual variation of these soil properties should be described. Geostatistical techniques such as ordinary kriging are suited to this. This paper describes the format of the databases and initial approaches as to how they can be used for digital soil mapping. For this paper we have selected soil pH to illustrate the analyses for both databases.

Assessment of a climate model to reproduce rainfall variability and extremes over Southern Africa

It is increasingly accepted that any possible climate change will not only have an influence on mean climate but may also significantly alter climatic variability. A change in the distribution and magnitude of extreme rainfall events (associated with changing variability), such as droughts or flooding, may have a far greater impact on human and natural systems than a changing mean. This issue is of particular importance for environmentally vulnerable regions such as southern Africa. The sub-continent is considered especially vulnerable to and ill-equipped (in terms of adaptation) for extreme events, due to a number of factors including extensive poverty, famine, disease and political instability. Rainfall variability and the identification of rainfall extremes is a function of scale, so high spatial and temporal resolution data are preferred to identify extreme events and accurately predict future variability. The majority of previous climate model verification studies have compared model output with observational data at monthly timescales. In this research, the assessment of ability of a state of the art climate model to simulate climate at daily timescales is carried out using satellite-derived rainfall data from the Microwave Infrared Rainfall Algorithm (MIRA). This dataset covers the period from 1993 to 2002 and the whole of southern Africa at a spatial resolution of 0.1° longitude/latitude. This paper concentrates primarily on the ability of the model to simulate the spatial and temporal patterns of present-day rainfall variability over southern Africa and is not intended to discuss possible future changes in climate as these have been documented elsewhere. Simulations of current climate from the UKMeteorological Office Hadley Centre’s climate model, in both regional and global mode, are firstly compared to the MIRA dataset at daily timescales. Secondly, the ability of the model to reproduce daily rainfall extremes is assessed, again by a comparison with extremes from the MIRA dataset. The results suggest that the model reproduces the number and spatial distribution of rainfall extremes with some accuracy, but that mean rainfall and rainfall variability is underestimated (over-estimated) over wet (dry) regions of southern Africa.

Political instability and the persistence of religion in Greece: the policy implications of the cultural defence paradigm

This paper examines the implications of ‘cultural defence’ in the nature of democracy and the stability of the political system in Greece. It focuses on the Greek Orthodox Church’s maintenance of power and political relevance by virtue of its strong link to national identity. We argue that the inhibition of secularization in Greece as a result of cultural defence has significant policy implications, especially in times of crises, when the role of nationalism as a cohesive factor against perceived threats is intensified. The paper further explores three policy/politics areas: (1) political orientation; (2) religious pluralism; and (3) education.

Political culture and corporate homicide liability in the UK and Europe

This chapter outlines recent developments in the emergence within Europe of systems of criminal law designed to hold corporate bodies liable where they cause the deaths of workers or members of the public. These changes point to the emergence of a new, more punitive, legal culture in relation to corporate crime. At the same time, however, there is evidence to suggest that this punitive culture is not uniform; different national jurisdictions reflect it to differing degrees. The chapter explores the degree to which the UK’s willingness to criminalise work-related deaths is mirrored elsewhere in Europe, and identifies some factors that might account for variations in this regard. In particular, attention is paid to the influence that social and political culture have on practices in this area. It is written as part of a research handbook on corporate crime in Europe, so has an eye on a more generalist audience in some regards.

Changes in fire regimes since the Last Glacial Maximum: an assessment based on a global synthesis and analysis of charcoal data

Fire activity has varied globally and continuously since the last glacial maximum (LGM) in response to long-term changes in global climate and shorter-term regional changes in climate, vegetation, and human land use. We have synthesized sedimentary charcoal records of biomass burning since the LGM and present global maps showing changes in fire activity for time slices during the past 21,000 years (as differences in charcoal accumulation values compared to pre-industrial). There is strong broad-scale coherence in fire activity after the LGM, but spatial heterogeneity in the signals increases thereafter. In North America, Europe and southern South America, charcoal records indicate less-than-present fire activity during the deglacial period, from 21,000 to ∼11,000 cal yr BP. In contrast, the tropical latitudes of South America and Africa show greater-than-present fire activity from ∼19,000 to ∼17,000 cal yr BP and most sites from Indochina and Australia show greater-than-present fire activity from 16,000 to ∼13,000 cal yr BP. Many sites indicate greater-than-present or near-present activity during the Holocene with the exception of eastern North America and eastern Asia from 8,000 to ∼3,000 cal yr BP, Indonesia and Australia from 11,000 to 4,000 cal yr BP, and southern South America from 6,000 to 3,000 cal yr BP where fire activity was less than present. Regional coherence in the patterns of change in fire activity was evident throughout the post-glacial period. These complex patterns can largely be explained in terms of large-scale climate controls modulated by local changes in vegetation and fuel load

Global patterns of plant root colonization intensity by mycorrhizal fungi explained by climate and soil chemistry

Aim Most vascular plants on Earth form mycorrhizae, a symbiotic relationship between plants and fungi. Despite the broad recognition of the importance of mycorrhizae for global carbon and nutrient cycling, we do not know how soil and climate variables relate to the intensity of colonization of plant roots by mycorrhizal fungi. Here we quantify the global patterns of these relationships. Location Global. Methods Data on plant root colonization intensities by the two dominant types of mycorrhizal fungi world-wide, arbuscular (4887 plant species in 233 sites) and ectomycorrhizal fungi (125 plant species in 92 sites), were compiled from published studies. Data for climatic and soil factors were extracted from global datasets. For a given mycorrhizal type, we calculated at each site the mean root colonization intensity by mycorrhizal fungi across all potentially mycorrhizal plant species found at the site, and subjected these data to generalized additive model regression analysis with environmental factors as predictor variables. Results We show for the first time that at the global scale the intensity of plant root colonization by arbuscular mycorrhizal fungi strongly relates to warm-season temperature, frost periods and soil carbon-to-nitrogen ratio, and is highest at sites featuring continental climates with mild summers and a high availability of soil nitrogen. In contrast, the intensity of ectomycorrhizal infection in plant roots is related to soil acidity, soil carbon-to-nitrogen ratio and seasonality of precipitation, and is highest at sites with acidic soils and relatively constant precipitation levels. Main conclusions We provide the first quantitative global maps of intensity of mycorrhizal colonization based on environmental drivers, and suggest that environmental changes will affect distinct types of mycorrhizae differently. Future analyses of the potential effects of environmental change on global carbon and nutrient cycling via mycorrhizal pathways will need to take into account the relationships discovered in this study.

A comparison between large-scale irregularities and scintillations in the polar ionosphere

A comparison tool has been developed by mapping the global GPS total electron content (TEC) and large coverage of ionospheric scintillations together on the geomagnetic latitude/magnetic local time coordinates. Using this tool, a comparison between large-scale ionospheric irregularities and scintillations are pursued during a geomagnetic storm. Irregularities, such as storm enhanced density (SED), middle-latitude trough and polar cap patches, are clearly identified from the TEC maps. At the edges of these irregularities, clear scintillations appeared but their behaviors were different. Phase scintillations (σsub{φ}) were almost always larger than amplitude scintillations (S4) at the edges of these irregularities, associated with bursty flows or flow reversals with large density gradients. An unexpected scintillation feature appeared inside the modeled auroral oval where S4 were much larger than σsub{φ}, most likely caused by particle precipitations around the exiting polar cap patches.
