El presente artículo tiene como finalidad analizar si realmente los pueblos indígenas de la Costa Caribe de Nicaragua se han beneficiado del estatus de autonomía en cuanto a lograr un mayor respeto de sus derechos como indígenas. En algunos países en vías de desarrollo se ha tomado en consideración la posibilidad de lograr el desarrollo, crecimiento económico y eliminación de desigualdades a través de procesos de descentralización. En el caso de Nicaragua, este proceso se llevó a cabo para dar respuesta a las necesidades de los pueblos indígenas de la Costa Caribe. Después de muchos años de lucha, los pueblos indígenas de la Costa Caribe o Costa Atlántica lograron su autonomía del gobierno central del país en 1987. El proceso en sí tomó 3 años para dar fruto al Estatuto de Autonomía de las Regiones de la Costa Atlántica de Nicaragua (Ley de Autonomía). Como pueblos con identidades propias, la autonomía fue la forma en que estos pueblos hicieran respetar sus diferencias como poblaciones indígenas. Hasta los años ochenta, ninguna de las Constituciones Políticas del Estado hacía referencia a las poblaciones indígenas del país, ésta población quedaba totalmente excluida. Con la Ley de Autonomía se reconocen las diferencias de los pueblos indígenas de las Costa Caribe y se les da el espacio para que éstos, partiendo de sus necesidades, distintas a las del resto del país, puedan tomar decisiones para satisfacer las necesidades específicas de sus culturas. Para poder analizar esta situación, primero, se desarrollará la historia de la población de la Costa Caribe, explicando la situación de los pueblos indígenas de esta región y su relación o falta de relación con el resto del país. Igualmente, se haré un breve resumen de la historia y la estructura de la autonomía regional, en el cual se indicará las diferentes etapas que se llevaron a cabo durante el proceso de autonomía. Por último, se exponen los desafíos actuales del pueblo indígena en cuanto a su autonomía y la situación de sus derechos después de haber logrado este estatus.

El poeta y ensayista cubano confiesa que la poesía le dio una razón para vivir, y que sigue siendo su gran amor. Aunque difícil de definir, plantea que al ser humano le resulta imposible resistir sin ella: en toda crisis (la enfermedad, la muerte o la guerra), se recurre a la poesía. Las influencias literarias le llegaron de escritores alemanes, franceses y latinoamericanos (sobre todo, de Jorge Luis Borges, José Lezama Lima, Octavio Paz y Alfonso Reyes). El autor cubano destaca los méritos de varios poetas ecuatorianos y latinoamericanos. De Lezama Lima, quien “vivía para la poesía y el espíritu, con apenas unos pesitos”, resalta su sentido coral de la cultura (como construcción colectiva) y de la literatura. Respecto de la Revolución, aun reconociendo que hubo errores, está convencido de que es lo mejor que pudo pasarle a Cuba, no solo porque es la que buscó con insistencia, de Martí a Lezama, sino porque es la que triunfó y sigue adelante, pese al bloqueo económico de medio siglo por parte de la mayor potencia mundial, y de todas las dificultades.

Basado en fuentes primarias (epistolarios), el artículo ofrece una aproximación al proceso de formación de grupos armados irregulares, en la provincia de Manabí, a inicios del siglo XIX, como consecuencia de la disputa por el poder y el control del monopolio de la violencia, en el marco de construcción del nuevo régimen republicano. En esta región periférica del Estado central, la sociedad se torna violenta cuando es presionada tanto por el poder estatal, como por los caudillos locales que pretenden formar parte de las estructuras de poder local por medio del reclutamiento forzoso para engrosar las filas de milicias y grupos armados.

This article explains how the colonial economic system was set up on the what is now the Ecuadorian coast. It also shows how social and precolonial economic forms funcioned and its articulation with the colonial economy. In this geographic zone where merchandise was exchanged and where people mingled and information was shared linking the distant mother country with the viceroyalty, the production and circulation of a wide array of goods provided the cornerstone for crestfallen indigenas societies. The sources provide evidence on the methods used by local rulers, who were essential actors in colonial implantation.

El presente trabajo es un análisis teórico de la obra del escritor argentino Macedonio Fernández (1874-1952). El objetivo de esta investigación es analizar la narrativa que presenta en algunos de sus cuentos –“Papeles de Recienvenido” (1929), “Tantalia” (1930), “Cirugía psíquica de extirpación” (1941), “A Fotografiarse” (1944), “Donde Solano Reyes era un vencido y sufría dos derrotas cada día” (1944)– y la teoría literaria que desarrolla en sus ensayos –sobre todo en “Para una teoría del Arte”. Para ello, se ha escogido a lo “imposible” como una categoría pertinente para problematizar la narrativa de Fernández, esto desde la tensión existente entre las categorías de ficción y realidad. En la narrativa macedoniana, la realidad se transforma por la operación de lo ficcional, lo que genera ciertos “imposibles” para una lógica de la realidad, siendo, al mismo tiempo, posibles para una lógica de lo ficcional. Por esta vía, se analizarán los conceptos teóricos propuestos por el autor – Belarte y Autorística– para ahondar y explicitar el lugar que estos tienen dentro de la narrativa que presenta en sus cuentos y para relacionarlos con las categorías que se han detallado. Además, cabe indicar que uno de los alcances de la presente investigación es el diálogo que se establece con la teoría lingüística de Roman Jakobson (1896-1982) y de Émile Benveniste (1902-1976), de quienes se recogen algunas de las propuestas que plantean en sus textos. Macedonio Fernández, aunque ha influenciado el estilo de escritores como Jorge Luis Borges y Julio Cortázar, es un autor poco estudiado en el ámbito académico latinoamericano. En el caso de estudios dentro de nuestro país, según la bibliografía revisada, no se ha hecho una investigación formal sobre la obra de este importante escritor de la vanguardia literaria argentina. Esta es una de las razones por las cuales se ha considerado necesaria la presente propuesta de trabajo.

We examined nest site selection by Puerto Rican Parrots, a secondary cavity nester, at several spatial scales using the nest entrance as the central focal point relative to 20 habitat and spatial variables. The Puerto Rican Parrot is unique in that, since 2001, all known nesting in the wild has occurred in artificial cavities, which also provided us with an opportunity to evaluate nest site selection without confounding effects of the actual nest cavity characteristics. Because of the data limitations imposed by the small population size of this critically endangered endemic species, we employed a distribution-free statistical simulation approach to assess site selection relative to characteristics of used and unused nesting sites. Nest sites selected by Puerto Rican Parrots were characterized by greater horizontal and vertical visibility from the nest entrance, greater density of mature sierra palms, and a more westerly and leeward orientation of nest entrances than unused sites. Our results suggest that nest site selection in this species is an adaptive response to predation pressure, to which the parrots respond by selecting nest sites offering advantages in predator detection and avoidance at all stages of the nesting cycle. We conclude that identifying and replicating the “nest gestalt” of successful nesting sites may facilitate conservation efforts for this and other endangered avian species.

Using topographic data collected by radar interferometry, stereo-photogrammetry, and field survey we have measured the changing surface of Volcan Arenal in Costa Rica over the period from 1980 to 2004. During this time this young volcano has mainly effused basaltic andesite lava, continuing the activity that began in 1968. Explosive products form only a few percent of the volumetric output. We have calculated digital elevation models for the years 1961, 1988 and 1997 and modified existing models for 2000 and 2004. From these we have estimated the volume of lava effused and coupled this with the data presented by an earlier study for 1968-1980. We find that a dense rock equivalent volume of 551 M m(3) was effused from 1968 to 2004. The dense rock equivalent effusion rate fell from about 2 m(3) s(-1) to about 0.1-0.2 m(3) s(-1) over the same period, with an average rate of about 0.5 m(3) s(-1). Between 1980 and 2004, the average effusion rate was 0.36 m(3) s(-1), a similar rate to that measured between 1974 and 1980. There have been two significant deviations from this long-term rate. The effusion rate increased from 1984 to 1991, at the same time as explosivity increased. After a period of moderate effusion rates in the 1990s, the rate fell to lower levels around 1999.

From 1997 onward, the strobilurin fungicide azoxystrobin was widely used in the main banana-production zone in Costa Rica against Mycosphaerella fijiensis var. difformis causing black Sigatoka of banana. By 2000, isolates of M. fijiensis with resistance to the quinolene oxidase inhibitor fungicides were common on some farms in the area. The cause was a single point mutation from glycine to alanine in the fungal target protein, cytochrome b gene. An amplification refractory mutation system Scorpion quantitative polymerase chain reaction assay was developed and used to determine the frequency of G 143A allele in samples of M. fijiensis. Two hierarchical surveys of spatial variability, in 2001 and 2002,found no significant variation in frequency on spatial scales <10 in. This allowed the frequency of G143A alleles on a farm to be estimated efficiently by averaging single samples taken at two fixed locations. The frequency of G 143A allele in bulk samples from I I farms throughout Costa Rica was determined at 2-month intervals. There was no direct relationship between the number of spray applications and the frequency of G143A on individual farms. Instead, the frequency converged toward regional averages, presumably due to the large-scale mixing of ascospores dispersed by wind. Using trap plants in an area remote from the main producing area, immigration of resistant ascospores was detected as far as 6 km away both with and against the prevailing wind.

This article examines how conventional studio production strategies were active in the construction of political meaning in the 1974 television play 'Absolute Beginners' written by Trevor Griffiths. Produced for the BBC anthology series Fall of Eagles, the play dramatises Lenin's involvement with the Russian Social Democratic Workers Party (RSDWP) and explores the contradictions between personal ethics and political necessity. Through close textual analysis and contextual discussion of other plays in the series, this piece demonstrates how shot patterns and spatial and performative devices in 'Absolute Beginners' supported the drama's socialist-humanist themes. Drawing on existing writing about the studio mode, it argues that the qualities of intimacy and presentational distance that it engendered were highly appropriate for the personal and the political dialectic in 'Absolute Beginners'. While using authorship as a convenient category for referring to the coherence of Griffiths' thematic concerns and dramatic structure during this period, the article complicates notions of the television dramatist as author by arguing for the importance of visual style and showing how 'ordinary' studio form was operational in the play's political meanings.

In many lower-income countries, the establishment of marine protected areas (MPAs) involves significant opportunity costs for artisanal fishers, reflected in changes in how they allocate their labor in response to the MPA. The resource economics literature rarely addresses such labor allocation decisions of artisanal fishers and how, in turn, these contribute to the impact of MPAs on fish stocks, yield, and income. This paper develops a spatial bio-economic model of a fishery adjacent to a village of people who allocate their labor between fishing and on-shore wage opportunities to establish a spatial Nash equilibrium at a steady state fish stock in response to various locations for no-take zone MPAs and managed access MPAs. Villagers’ fishing location decisions are based on distance costs, fishing returns, and wages. Here, the MPA location determines its impact on fish stocks, fish yield, and villager income due to distance costs, congestion, and fish dispersal. Incorporating wage labor opportunities into the framework allows examination of the MPA’s impact on rural incomes, with results determining that win-wins between yield and stocks occur in very different MPA locations than do win-wins between income and stocks. Similarly, villagers in a high-wage setting face a lower burden from MPAs than do those in low-wage settings. Motivated by issues of central importance in Tanzania and Costa Rica, we impose various policies on this fishery – location specific no-take zones, increasing on-shore wages, and restricting MPA access to a subset of villagers – to analyze the impact of an MPA on fish stocks and rural incomes in such settings.

Tropical forests have been subject to intense hunting of medium and large frugivores that are important in dispersing large-seeded species. It has been hypothesized that in areas with extinction or low abundance of medium and large-bodied animals the density of small rodents may increase. Therefore, this increment in the density of small rodents may compensate for the absence or low abundance of medium and large frugivores on seed removal and seed dispersal. Here, we fill up this gap in the literature by determining if seed removal, seed dispersal, and seed predation by small rodents (spiny rats, Trinomys inheringi and squirrels, Sciurus ingrami) are maintained in defaunated areas. We accessed seed removal, seed dispersal, seed predation, and seedling recruitment of an endemic Atlantic rainforest palm, Astrocaryum aculeatissimum, in a gradient of abundance of agoutis. We found that seed removal, scatter hoarding, and seed predation increase with the abundance of agoutis. In contrast, the proportion of dispersed but non-cached seeds decreased with the abundance of agoutis. We did not find any effect of the abundance of agoutis on seed dispersal distance, but we did find a positive trend on the density of seedlings. We concluded that small rodents do not compensate the low abundance of agoutis on seed removal, scatter hoarding, and seed predation of this palm tree. Moreover, areas in which agoutis are already extinct did not present any seed removal or scatter hoarding, not even by small rodents. This study emphasizes both the importance of agoutis in dispersing seeds of A. aculeatissimum and the collapse in seed dispersal of this palm in areas where agoutis are already extinct.

In many mammals social organization promotes genetic structuring, which can be influenced by the dispersal pattern of the species. We analyzed the population genetic structure and dispersal of white-lipped peccaries (Tayassu pecan) from the Pantanal, Brazil. We genotyped 100 individuals at 7 microsatellite loci from 2 adjacent locations with no obvious geographic barrier between them. We found a significant but low F(ST) value, and the Bayesian analysis indicated a unique cluster. No significant differences were observed between mean assignment indices of resident males and females from both locations, and the probability of being born at the location sampled of > 30% of the individuals analyzed was lower than average. Mean relatedness between resident female, male, and opposite-sex pairs was not statistically different in both locations. These results suggest a low degree of genetic differentiation between the locations analyzed, and dispersal by both sexes (contrary to the predicted male-biased dispersal of most mammalian species).

Objective: It was the aim of this study to evaluate whether chronic pain in athletes is related to performance, measured by the maximum oxygen consumption and production of hormones and cytokines. Methods: Fifty-five athletes with a mean age of 31.9 +/- 4.2 years engaged in regular competition and showing no symptoms of acute inflammation, particularly fever, were studied. They were divided into 2 subgroups according to the occurrence of pain. Plasma concentrations of adrenaline, noradrenaline, cortisol, prolactin, growth hormone and dopamine were measured by radioimmunoassay, and the production of the cytokines interleukin (IL)-1, IL-2, IL-4, IL-6, tumor necrosis factor-alpha, interferon-alpha and prostaglandin E-2 by whole-blood culture. Maximal oxygen consumption was determined during an incremental treadmill test. Results: There was no change in the concentration of stress hormones, but the athletes with chronic pain showed a reduction in maximum oxygen consumption (22%) and total consumption at the anaerobic threshold (25%), as well as increased cytokine production. Increases of 2.7-, 8.1-, 1.7- and 3.7-fold were observed for IL-1, IL-2, tumor necrosis factor-alpha and interferon-alpha, respectively. Conclusions: Our data show that athletes with chronic pain have enhanced production of proinflammatory cytokines and lipid mediators and reduced performance in the ergospirometric test.

Samples of Araucaria area soil from Parana state, Brazil, were separated by particle size fractionation and investigated by electron paramagnetic resonance (EPR) in X-Band of 9.5 GHz at room temperature and 77K, infra-red spectroscopy and X-ray diffractometry. The paramagnetic species in the soil samples were identified by comparison with EPR spectra of some minerals studied recently by our group, several soil types and/or soil components investigated in the literature. The value of g = 2.1 (Delta H = 85 mT) indicated the presence of ferrihydrite. Hematite was identified by g = 2.1 (Delta H = 100 mT) and g = 4.3 for Fe(3+) lines of the concentrated dominium and diluted dominium. Kaolinite was identified by IR and EPR with the resonance at g = 4.3 attributed to Fe(3+) ions in isolated sites of tetrahedral and octahedral symmetry with rhombic distortion. The resonances at g = 3.7 and g = 4.9 were attributed to Fe(3+) in more highly symmetrical environment than rhombic symmetry, but not in axial symmetry. Three signals around g = 2 were attributed to radiation defects, plus additional resonances at g = 2.8 and 9.0. Signals less intense than those at g = 2.1, 3.7, and 6.5, observed for clear grains of soil, were attributed to presence of Fe(3+) in quartz which was identified by IR and XDR. (C) 2011 Elsevier B.V.
