Holocene paleoclimate inferred from salinity histories of adjacent lakes in southwestern Sicily (Italy)

2016

Marked uncertainties persist regarding the climatic evolution of the Mediterranean region during the Holocene. For instance, whether moisture availability gradually decreased, remained relatively constant, or increased during the last 7000 years remains a matter of debate. To assess Holocene limnology, hydrology and moisture dynamics, the coastal lakes Lago Preola and Gorgo Basso, located in southwestern Sicily, were investigated through several stratigraphic analyses of ostracodes, including multivariate analyses of assemblages, transfer functions of salinity, and biochemical analyses of valves (Sr/Ca, δ18O and δ13C). During the early Holocene, the Gorgo Basso and Lago Preola ostracode rec…

From the Ultimate God to the Virtual God: Post-Ontotheological Perspectives on the Divine in Heidegger, Badiou, and Meillassoux

2014

The Heideggerian account of the ontotheological constitution of Western metaphysics has been extremely influential for contemporary philosophy of religion and for philosophical perspectives on theology and the divine. This paper introduces and contrasts two central strategies for approaching the question of the divine in a non- or post-ontotheological manner. The first and more established approach is that of post-Heideggerian hermeneutics and deconstruction, inspired by Heidegger’s suggestion of a “theology without the word ‘being’” and by his later notions of an “ultimate god” and of “divinities” as one of the four axes of the fourfold (Geviert). Here, the divine is no longer articulated …

Toward fast malaria detection by secondary speckle sensing microscopy

2012

Diagnosis of malaria must be rapid, accurate, simple to use, portable and low cost, as suggested by the World Health Organization (WHO). Despite recent efforts, the gold standard remains the light microscopy of a stained blood film. This method can detect low parasitemia and identify different species of Plasmodium. However, it is time consuming, it requires well trained microscopist and good instrumentation to minimize misinterpretation, thus the costs are considerable. Moreover, the equipment cannot be easily transported and installed. In this paper we propose a new technique named "secondary speckle sensing microscopy" ((SM)-M-3) based upon extraction of correlation based statistics of s…

PASSIONATE DESCARTES: A REINTERPRETATION OF THE BODY'S ROLE IN CARTESIAN THOUGHT

2020

Abstract The usual reading of Descartes' “anthropological” perspective classifies it as a radical dualism with a distinction between two substances, mind and body, which experience major interaction difficulties. Through a contextualization of Descartes' physiological and psychological thought as well as through a less fragmented reading of his work, we intend to review this traditional interpretation, thereby showing its distorted character. When we pay attention to passion, a new Descartes’ image as a sort of phenomenal monism appears, which is markedly different from the legendary image typically associated with him, even today.

The non-bilayer lipid MGDG stabilizes the major light-harvesting complex (LHCII) against unfolding.

2017

Abstract In the photosynthetic apparatus of plants a high proportion of LHCII protein is needed to integrate 50% non-bilayer lipid MGDG into the lamellar thylakoid membrane, but whether and how the stability of the protein is also affected is not known. Here we use single-molecule force spectroscopy to map the stability of LHCII against mechanical unfolding along the polypeptide chain as a function of oligomerization state and lipid composition. Comparing unfolding forces between monomeric and trimeric LHCII demonstrates that the stability does not increase significantly upon trimerization but can mainly be correlated with specific contact sites between adjacent monomers. In contrast, unfol…

Nihilism as the absence of goals and its overcoming in be-ing historical thinking

2020

La publicación, desde 1989, de los tratados póstumos sobre la historia del Ser profundiza el sentido del problema del nihilismo en la filosofía de Heidegger. En el presente artículo buscamos demostrar que estos textos (de las Contribuciones a la filosofía a los Cuadernos negros) permiten una nueva perspectiva interpretativa del pensar histórico del Ser: la de ausencia de fines (Zielen) y la búsqueda como fin en sí mismo. Esto nos ayuda a entender mejor tanto el problema del nihilismo en Heidegger, como la forma especial que adopta su solución: la superación del nihilismo en el pensar del Ereignis. Since 1989, the publication of the posthumous works of Heidegger has been deepening the meanin…

El escultor del tiempo: claves de la “filosofía cinematográfica” de Gilles Deleuze

2018

Gilles Deleuze ha ofrecido en sus dos estudios sobre cine —L’image–mouvement y L’image– temps— una de las propuestas más ambiciosas de las últimas décadas en lo que concierne a la relación entre filosofía y cine, hasta el punto de construir una auténtica “filosofía cinematográfica” y de inaugurar, en paralelo a Stanley Cavell, una fructífera línea de investigación filosófica que ha dado en denominarse como “film–philosophy”. Su primera obra se centra, fundamentalmente, en elaborar una metafísica del tiempo inspirada en la filosofía de Henri Bergson, pero utilizando las posibilidades del cine para complementar y trascender las ideas del autor de L’évolution créatice. En su se…

Nietzsche y el mejoramiento humano. Reflexiones en torno a la noción de vida

2017

El presente trabajo expone el diálogo entre nietzsche y la escuela darwinista, destacando el contraste entre dos nociones de «vida» opuestas: vida como lucha por la supervivencia o vida como voluntad de poder. En oposición a la selección natural, que según nietzsche no favorece a los fuertes y poderosos sino a lo mediano y al «gran número», el filósofo alemán idea un proyecto de cría (Züchtung), una formación tanto fisiológica como moral que aspira a una auténtica elevación del ser humano, mediante la superación de las interpretaciones nihilistas y la transvaloración de los valores desde una perspectiva vitalista.

¿Un transhumanismo nietzscheano? Sobre la parcialidad del alegato

2020

espanolEl articulo analiza desde una perspectiva critica las tentativas de interpretar a Nietzsche como un precursor del transhumanismo. Tras una breve contextualizacion del fecundo debate en torno a Nietzsche y el transhumanismo, se evalua el caracter fraccional o parcial del alegato de Stefan Sorgner en favor de un “transhumanismo nietzscheano”. Despues, se investiga la tension entre humanidad, la superacion del ser humano y su cria en los escritos de Nietzsche. Una vez ejecutado este analisis, y sin animo de caer en el anacronismo, se sostiene que Nietzsche anticipa ciertamente un germen de la idea de post-humanidad, en su critica de la cultura humanista y en su invitacion a transformar …
