Carlo Ginzburg. Cuando el historiador amoneda un símbolo
2020
Resumen En este artículo pretendemos analizar la trayectoria, la contribución, los resultados y la influencia de un historiador de renombre mundial, Carlo Ginzburg. La suya es una investigación de largo recorrido, cuya influencia se ha dado no sólo en esta rama del saber, sino también en muy distintos ámbitos de las humanidades, de las ciencias, de las artes. Carlo Ginzburg ha sido reconocido e identificado principalmente a partir de dos logros historiográficos: la microhistoria y El queso y los gusanos. Por un lado, se le ve como el máximo representante de la microhistoria, la corriente de origen italiano que se expande principalmente en los años ochenta del siglo XX. Por otro lado, a este…
Una realidad social escindida: Las memorias de las peras y las manzanas en el Chile reciente
2014
Forty years after the military coup that bloodied Chile during the years of military dictatorship, the country is still splitted with a society which is still in a traumatic situation. In this paper we have worked with audio-visual sources, which we call Video Format Documents (VFD), produced from the sixties onwards. This article is based on sources that allow us a deeper understanding of the society in which they were produced; a society −as it is said by a character of one of the most successful films in Chile−, divided into pears and apples.
De los detalles al todo: historia cultural y biografías globales
2013
Este artículo aborda algunas de las nuevas direcciones de la historia cultural. En particular, los trabajos de algunos estudiosos que emplean una perspectiva global. Esa elección plantea algunos problemas, sobre todo los relativos a las aparentes contradicciones entre la tradicional mirada micro, que ha sido característica de la historia cultural más significativa, y la macro, en la que acostumbraba a primar el análisis económico o político. ¿Cómo analizar un individuo desde una perspectiva global? Utilizando principalmente las reflexiones de Peter Burke o Natalie Zemon Davis, el artículo expone que esa preocupación es un asunto actual, propio de una época de interconexión acelerada, que re…
¿Que Historia de España Enseñar?
2005
España representa mucho más que un término para designar un lugar en el mapa o una mera “superestructura” política sustentada en exclusiva por ideas y voluntades. Producto cultural humano, resulta por encima de todo un hecho histórico colectivo, de larga duración, contingente, variable, complejo y problemático, de una entidad y trascendencia que llegan hasta nuestros días. Al igual que cualquier otro hecho histórico, requiere de la historia para entenderlo en sus distintas dimensiones. Por ello, nada tiene de extraño que la historia de España sea a partir de cierta edad una materia básica del currículo de los estudiantes en la enseñanza secundaria obligatoria y continúe como tal en los dist…
The United Citizens Organization: Public-private partnerships in global governance
2020
Abstract Can Public-Private Partnerships be applied to global affairs and governance? This paper reviews the existing relations between public and private global actors. I argue that current international politics is largely an outcome of these relations. Although for the foreseeable future the role of traditional nation-states on the global scene should not be dismissed, they come under the constant pressure of different private actors, particularly of MNCs and NGOs. If this is the case, the question of global responsibility must be raised. It has been the traditional role of governments to stand for such societal values as security and prosperity, and be responsible for their citizens. Wi…
Documentação digital da arte rupestre: apresentação e avaliação do método em dois sítios de Monte Alegre, Amazônia, Brasil
2013
Um dos aspectos mais importantes no estudo da arte rupestre é a documentação. No Brasil, são raros os trabalhos que apresentam os métodos e as técnicas empregados na documentação deste tipo de vestígio arqueológico. Grande parte dos estudos publicados no país está voltada para a classificação, a terminologia, as definições crono-estilísticas, interpretações e comparações entre conjuntos gráficos. Atualmente, a fotografia digital e os programas de manipulação de imagem constituem ferramentas de grande utilidade e precisão para a documentação da arte rupestre. Este artigo apresenta os resultados da aplicação do método do decalque digital na Amazônia, desenvolvido pelo Departamento de Arqueolo…
Neoclassical growth, manufacturing agglomeration, and terms of trade
2007
This paper presents an integrated view of economic growth, development traps, and economic geography. We explain why there is income convergence among some countries (neoclassical regime) and income divergence among others (poverty trap regime). Income convergence (divergence) and manufacturing industry diffusion (agglomeration) are re-enforcing each other in a cumulative process. Moreover, trade openness may trigger a catch-up process of an economy that is stuck in a \"poverty trap\". This catch-up is characterized by an increase in the investment-to-GDP ratio and an improvement of the terms of trade. A new dynamic welfare gain of trade liberalization is identified, which is likely to be l…
Physical characterization of alginate-Pluronic F127 gel for endoluminal NABDs delivery
2014
Here we focus the attention on the physical characteristics of a highly biocompatible hydrogel made up of crosslinked alginate and Pluronic F127 (PF127). This is a composite polymeric blend we propose for artery endoluminal delivery of an emerging class of molecules named nucleic acid based drugs (NABDs). The physical characterization of our composite gel, i.e. mesh size distribution and PF127-alginate mutual organization after crosslinking, can significantly determine the NABDs release kinetics. Thus, to explore these aspects, different technical approaches, i.e. rheology, low/high field NMR and TEM, were used. While rheology provided information at the macroscopic and nano-level, the othe…
X-ray Tomography of One-forms with Partial Data
2021
If the integrals of a one-form over all lines meeting a small open set vanish and the form is closed in this set, then the one-form is exact in the whole Euclidean space. We obtain a unique continuation result for the normal operator of the X-ray transform of one-forms, and this leads to one of our two proofs of the partial data result. Our proofs apply to compactly supported covector-valued distributions.
On Radon Transforms on Tori
2014
We show injectivity of the X-ray transform and the $d$-plane Radon transform for distributions on the $n$-torus, lowering the regularity assumption in the recent work by Abouelaz and Rouvi\`ere. We also show solenoidal injectivity of the X-ray transform on the $n$-torus for tensor fields of any order, allowing the tensors to have distribution valued coefficients. These imply new injectivity results for the periodic broken ray transform on cubes of any dimension.
