Memorias montoneras: metáforas de la guerra en Argentina (Crítica)

La autora lee la novela de Sergio Pollastri desde la perspectiva crítica de las posibilidades e imposibilidades de la reconstrucción de una historia, a partir de este relato testimonial que se mueve en el territorio de la violencia y las armas (la militancia política) y en el de la subjetividad (la poesía, la ficción). Resalta los vínculos entre vida y literatura, que cruzan toda la novela, así, apela a la metáfora para referirse a dos tipos de silencios en las ficciones sobre la violencia revolucionaria: la opción por las armas y la delación bajo tortura. Resalta el rol de la metáfora en este texto que tensa hasta sus límites el género testimonial, y que cobra su mayor fuerza hacia el final: «La revolución es frágil y superficial como una violeta, aquello que la comparación desarrolla es al mismo tiempo lo que amortigua la caída del salto brutal al vacío con el que la novela cierra su enunciación».

Paradojas e incertidumbres de las economías andinas (Coyuntura)

El artículo parte de señalar la contradicción entre un desempeño macroeconómico, generalmente calificado como favorable, de las economías andinas en lo que va del presente siglo, sustentado en mayores tasas de crecimiento del PIB Y en la reducción del ritmo inflacionario, con el significativo agravamiento de la inestabilidad política en la región, que se ha constituido en la zona más conflictiva del continente. Posteriormente, se examina detenidamente el comportamiento de las economías andinas, estableciendo sus limitaciones y sobre todo los elevados niveles de desempleo en todos los países andinos, como factores estructurales que unidos a la crisis de sus instituciones políticas configuran una situación paradójica y muy frágil. En este contexto, la apuesta al TLC que realizan tres de sus miembros, con diversos grados de decisión, significa una seria amenaza para la integración andina y abre serias dudas sobre el balance de costos y beneficios.

Economías andinas: también atrapadas por la crisis (Coyuntura)

Este artículo analiza los principales elementos de las crisis en América Latina y sus expresiones en la Comunidad Andina de Naciones (CAN), enfatizando algunas repercusiones en el proceso de integración andina. El autor señala que los países miembros de la CAN presentan un cuadro de debilidad económica y de fragilidad política cuyas perspectivas parecen prolongarse afectadas por las dificultades que atraviesan otras economías como la norteamericana, europea o japonesa, lo que pone en evidencia el poco éxito del modelo económico imperante. Finalmente analiza el papel y las posibilidades de los mecanismos multilaterales y regionales sobre las economías andinas.

El retrato modernista ecuatoriano: simbolismo, mujer y exotismo en Abelardo (1895), de Eudófilo Álvarez (Dossier: La novela ecuatoriana del siglo XIX)

Abelardo (1895) es una novela enmarcada en el Modernismo literario hispanoamericano tanto por sus influencias del simbolismo francés, como de los planteamientos estéticos del movimiento modernista. El sueño y el influjo de este en la vida terrena del narrador-personaje, la transformación de la imagen de la mujer frágil y virginal en la mujer fatal, el exotismo puesto en la mirada sobre lo indígena, lo campesino y los mitos homéricos, y la representación idealizada de la actitud modernista en el héroe de la novela, son algunos de los rasgos que caracterizan a la obra de Eudófilo Álvarez.

Self-Fulfilling Crises in the Eurozone: An Empirical Test. CEPS Working Document No. 366, 22 June 2012

This paper tests the hypothesis that government bond markets in the eurozone are more fragile and more susceptible to self-fulfilling liquidity crises than in stand-alone countries. We find evidence that a significant part of the surge in the spreads of the PIGS countries (Portugal, Ireland, Greece and Spain) in the eurozone during 2010-11 was disconnected from underlying increases in the debt-to-GDP ratios and fiscal space variables, and was the result of negative self-fulfilling market sentiments that became very strong since the end of 2010. We argue that this can drive member countries of the eurozone into bad equilibria. We also find evidence that after years of neglecting high government debt, investors became increasingly worried about this in the eurozone, and reacted by raising the spreads. No such worries developed in stand-alone countries despite the fact that debt-to-GDP ratios and fiscal space variables were equally high and increasing in these countries.

Beyond retrenchment over Iran: can the EU offer a framework for regional security? CEPS Commentary, 3 September 2012

A new and far-reaching round of sanctions imposed recently on Iran by the EU is starting to hurt the country, its economy and its citizens. Yet Iran’s leadership seems deaf to demands for international weapons inspectors to be allowed unhindered access to its nuclear enrichment facilities. With a regime that is not likely to sway to international and domestic pressure, and in view of the shifting strategic landscape in the Middle East, the question is whether the twin-track approach of sanctions and diplomacy should be kept up, or whether it should make way for an alternative set of policies that could preserve the fragile stability in the wider Middle East and turn a vicious circle into a virtuous one. In this new Commentary, CEPS Senior Research Fellow Steven Blockmans argues that the High Representative of the EU for Foreign Affairs and Security Policy, supported by the European External Action Service, is in a good position to offer a negotiated way out of this seemingly intractable situation.

Children's sociospatial (re)production of disability within primary school playgrounds

There is a contemporary shift in the institutional context of 'disabled' children's education in the United Kingdom from segregated special to mainstream schools. This change is tied to wider deinstitutionalised or reinstitutionalised geographies of disabled people, fragile globalised educational 'inclusion' agendas, and broader concerns about social cohesiveness. Although coeducating children is expected to transform negative representations of (dis)ability in future society, there are few detailed explorations of how children's everyday sociospatial practices (re)produce or transform dominant representations of (dis)ability. With this in mind, children's contextual and shifting performances of (dis)ability in two case study school playground (recreational) spaces are explored. The findings demonstrate that children with mind-body differences are variously (dis)abled, in comparison with sociospatially shifting norms of ability, which have body, learning, and emotional-social facets. The discussion therefore places an emphasis on the need to incorporate 'intellectual' and 'emotional' differences more fully into geographical studies of disability and identity. The paper has wider resonance for transformative expectations placed on colocating children with a variety of 'axes of difference' (such as gender, 'race, ethnicity, and social class) in schools.

The need for sustainable remediation

Humanity requires healthy soil in order to flourish. Soil is central to food production, the regulation of greenhouse gases, recreational areas such as parks and sports fields and the creation of an environment pleasing to the eye. But soil is fragile and easily damaged by uninformed management or accidents. One type of damage is contamination by chemicals that provide the lifestyles to which the developed world has become accustomed. Traditional soil "clean-up" has entailed either simple disposal or isolation of contaminated soil. Clearly this is not sustainable. Modern remedial techniques apply mineralogical and geochemical knowledge to clean up contaminated soil and make it good for reuse, rather than simply discarding this precious and finite resource.

NATO, Britain, France and the FRG: Nuclear Strategies and Forces for Europe, 1949-2000

This is vol. I of my two-volume study of the nuclear strategies/strategy preferences of NATO collectively, and individually of Britain, France, and West Germany in the Cold War. It shows that NATO strategy was a fragile compromise, and that these three countries, all within range of Soviet medium/intermediate range nuclear missiles and thus with less geostrategic difference than in previous military threat contexts, had wildly divergent strategies/preferences which cannot be explained merely by geography. It raises the question of what made them so different, addressed in Volume II "Nuclear Mentalities" (q.v.)

Britain as a global power in the twentieth century

This chapter examines the extent to which Britain's status as a global power in the twentieth century was underpinned by the existence of its empire. It suggests that, in a military sense, empire represented an uncertain resource. While the mobilization of the empire in the two world wars was ultimately crucial to British victory, its latent power in the years leading to those conflicts was poorly appreciated, not least by UK policy‐makers themselves. As such, it had limited value as a deterrent to Britain's enemies. Furthermore, the process of mobilizing the empire for war placed an almost intolerable strain on the fragile structures of imperial control. Britain's continuing aspirations to play the role of a global power following post‐war decolonization reflect the extent to which its overseas interests had always transcended the formal boundaries of empire. Meanwhile the Anglo‐American alliance provided Britain with a degree of security that its empire had never offered.

Harnessing the ancestors: mutuality, uncertainty and ritual practice in the Eastern Cape Province, South Africa

In the Eastern Cape Province of South Africa, chronic economic uncertainty has seen social relations stretched to breaking point. Informants speak of a 'war between men and women'. While grinding poverty, death in the shape of the 'axe' (HIV/AIDS) and suspicion stalk the land, and the project of building the umzi (homestead) falters, hope for the future and with it, trust between people, leaches away. One response to such uncertainty is a turn to ritual. Through a nearly relentless schedule of ritual activity which invokes the ancestors and the Christian deity in various forms, Xhosa people attempt to dam up trust, secure ongoing investment in the rural homestead and sustain ties of reciprocity both among rural people and between them and their urban kin. It is also through the staging of these rituals that women, acting together and in support of each other, are increasingly assertive – often in the face of a violent, rearguard opposition from men - in their efforts to exercise agency over the differentiated, fragmented and fragile social and economic relationships within their homesteads and across their villages.

Culex pipiens development is greatly influenced by native bacteria and exogenous yeast

Culex pipiens is the most cosmopolitan mosquito of the Pipiens Assemblage. By studying the nature of interactions between this species and microorganisms common to its breeding environment we can unravel important pitfalls encountered during development. We tested the survival rate of larval stages, pupae and adults of a Cx. pipiens colony exposed to a variety of microorganisms in laboratory conditions and assessed the transmission to offspring (F1) by those organisms that secured development up to adulthood. Three complementary experiments were designed to: 1) explore the nutritional value of yeasts and other microorganisms during Cx. pipiens development; 2) elucidate the transstadial transmission of yeast to the host offspring; and 3) to examine the relevance of all these microorganisms in female choice for oviposition-substratum. The yeast Saccharomyces cerevisiae proved to be the most nutritional diet, but despite showing the highest survival rates, vertical transmission to F1 was never confirmed. In addition, during the oviposition trials, none of the gravid females was attracted to the yeast substratum. Notably, the two native bacterial strains, Klebsiella sp. and Aeromonas sp., were the preferred oviposition media, the same two bacteria that managed to feed neonates until molting into 2nd instar larvae. Our results not only suggest that Klebsiella sp. or Aeromonas sp. serve as attractants for oviposition habitat selection, but also nurture the most fragile instar, L1, to assure molting into a more resilient stage, L2, while yeast proves to be the most supportive diet for completing development. These experiments unearthed survival traits that might be considered in the future development of strategies of Cx. pipiens control. These studies can be extended to other members of the Pipiens Assemblage

Histologic Evaluation of the Buccal and Lingual Bone Plates in Anterior Dog Teeth: Possible Influence on Implant Dentistry

Background: Recent studies in animals have shown pronounced resorption of buccal bone plate after immediate implantation. The sectioning of experimental material for histologic evaluation of the bone plates could provide valuable information about the possible effect of bone exposure in periodontal and implant surgeries. Methods: Twenty-four incisors were collected from dogs. After decalcification, the blocks were immersed in paraffin and bucco-lingual histologic sections were examined under light microscope. Some sections were reserved for immunohistochemical analysis. Results: The bone density, the width of the bone plates, and the percentage of vessels presented in the periodontal ligament and periosteum were analyzed in the buccal and lingual bone plates, which were divided corono-apically into thirds. The buccal bone plates showed statistically higher bone density compared to the lingual bone plates in the coronal thirds. The width of both bone plates increased from the coronal to the apical third, but all the buccal thirds were significantly thinner compared to the lingual thirds. No statistically significant differences were found between the bone plates for the percentage of area occupied by the blood vessels in the periodontal ligament or periosteum. Conclusion: It is reasonable to conclude that the higher bone density, represented by the lower number of marrow spaces, in association with the thinner aspect of the buccal bone plates made them more fragile to absorb compared to the lingual bone plates, especially during mucoperiosteal procedures.

The search for primordial quark nuggets among near Earth asteroids

Primordial Quark Nuggets, remnants of the quark-hadron phase transition, may be hiding most of the baryon number in superdense chunks have been discussed for years always from the theoretical point of view. While they seemed originally fragile at intermediate cosmological temperatures, it became increasingly clear that they may survive due to a variety of effects affecting their evaporation (surface and volume) rates. A search of these objects have never been attempted to elucidate their existence. We discuss in this note how to search directly for cosmological fossil nuggets among the small asteroids approaching Earth. `Asteroids` with a high visible-to-infrared flux ratio, constant lightcurves and devoid of spectral features are signals of an actual possible nugget nature. A viable search of very definite primordial quark nugget features can be conducted as a spinoff of the ongoing/forthcoming NEAs observation programmes.

Consequences of Simulated Loss of Open Cerrado Areas to Bird Functional Diversity

Over the past 35 years, more than two thirds of the Cerrado`s original expanse has been taken by agriculture. Even if some attempts have been made to conserve closed cerrado physiognomies, open cerrado physiognomies, richer in species and more fragile, have been systematically ignored. These open physiognomies are used by almost half of the Cerrado bird species, many of which being endemics. Using data from 11 surveys carried out in Cerrado landscapes, we asked what would happen to bird functional diversity if open cerrado species became extinct. Open cerrado birds would be able to keep on average 59% of the functional diversity. If they became extinct, on average 27% of the functional diversity would be lost. In this case, the remaining functional diversity would be lower than what would be expected by chance in five sites. Although many functions were shared by both open cerrado and forest species, there was some degree of complementarity between them, highlighted by the decrease in functional diversity when the former became extinct. Destruction of open cerrado physiognomies would lead to a habitat simplification, decrease in bird functional diversity, and, ultimately, to a considerable impact on community functioning. Thus, open cerrado physiognomies must receive much more conservation attention than they are currently receiving, because they maintain a high bird functional diversity that would otherwise be considerably diminished Were open cerrado species to become extinct.
