Implementation of space satellite remote sensing programs in developing countries (Ecuador)
The current state of space satellite remote sensing programs in developing countries is discussed. Sensors being utilized and results obtained are described. Requirements are presented for the research of resources in developing countries. It is recommended that a work procedure be developed for the use of satellite remote sensing data tailored to the necessities of the different countries
The Study of Islamic Origins in the Last Four Decades: Controversies and Perspectives
Virtually no scholar doubts that the so-called Deuteronomist –‘Second
Law’- history, included in the biblical corpus to configure some of the
main books that compose it, was written during the Babylonian exile and
subsequently revised. And this doubt does not take place because the historicalcritical study of the biblical text, as well as the historical analysis of the
corresponding period, have come to show that the compilation and definitive
writing of the historical books of the Bible took place in a much later time than
the dogmatically established. A similar historical-critical method is also applied
today to the study of the Qur’anic texts, although with much less follow-up and
still surrounded by a series of narrative stereotypes associated with Islamic
dogma but which among many scholars is no less dogmatic.Prácticamente ningún estudioso duda de que la llamada historia
deuteronomista o “de la segunda Ley”, incluida en el corpus bíblico para
configurar algunos de los principales libros que lo componen, fue redactada
durante el exilio babilónico y revisada posteriormente. Y no se produce esa duda
porque el estudio histórico-crítico del texto bíblico, así como el análisis histórico
del periodo correspondiente, han venido a mostrar, que la compilación y definitiva
puesta por escrito de los libros históricos de la Biblia tuvo lugar en una época
mucho más tardía de lo dogmáticamente establecido. Pues bien, similar método
histórico-crítico se aplica hoy en día también al estudio del texto coránico, si
bien con mucho menor seguimiento y aún rodeado de una serie de estereotipos
narrativos asociados al dogma islámico pero que entre numerosos estudiosos no
es menos dogmático
Univocismo y monadología en el pensamiento iraní postaviceniano. La prosecución filosófica del Irfan de Ibn al-Arabi en la obra de Sadrá Sirázi.
Las nociones de "uno" y de "múltiple" han sido, históricamente, objeto de tratamiento, a la vez, filosófico y teológico. En el contexto de la filosofía islámica oriental, y en el marco de su vertiente más específicamente neoplatónica, el "Príncipe de los Teósofos", Sadrá Sirázi (ob. 1050/1640), estudia ambas desde una perspectiva ontológica y distanciándose del enfoque consignado al respecto por los filósofos peripatéticos del Islam. Adaptando y continuando, de un lado, la gnosis de 1km aI-'Arabi, y, de otro, la sabiduria iluminativa de Sohravardi, MollA Sadrá discute la distinción aviceniana entre un Ser Necesario y una multiplicidad de seres posibles, así como la posibilidad de considerar accidental la realidad de la existencia. Basado en la eoimplicación de tres conceptos fundamentales: i~álat al-wu9ñd (prioridad del ser), i,vahdat al-wu9i2d (unidad del ser) y tagkik (diferenciación y gradación intensiva del ser), el univocismo monadológico de 5adrá puede, por otra parte, permitirnos reevaluar ciertas cuestiones filosóficas que pugnan por ser examinadas hoy a una nueva luz

Shaping plasmon beams via the controlled illumination of finite-size plasmonic crystals
Plasmonic crystals provide many passive and active optical functionalities, including enhanced sensing, optical nonlinearities, light extraction from LEDs and coupling to and from subwavelength waveguides. Here we study, both experimentally and numerically, the coherent control of SPP beam excitation in finite size plasmonic crystals under focussed illumination. The correct combination of the illuminating spot size, its position relative to the plasmonic crystal, wavelength and polarisation enables the efficient shaping and directionality of SPP beam launching. We show that under strongly focussed illumination, the illuminated part of the crystal acts as an antenna, launching surface plasmon waves which are subsequently filtered by the surrounding periodic lattice. Changing the illumination conditions provides rich opportunities to engineer the SPP emission pattern. This offers an alternative technique to actively modulate and control plasmonic signals, either via micro- and nano-electromechanical switches or with electro- and all-optical beam steering which have direct implications for the development of new integrated nanophotonic devices, such as plasmonic couplers and switches and on-chip signal demultiplexing. This approach can be generalised to all kinds of surface waves, either for the coupling and discrimination of light in planar dielectric waveguides or the generation and control of non-diffractive SPP beams
Metaphoric Recursiveness and Ternary Ontology: Another Look at the Language and Worldview of the Yaminahua
My purpose in this paper is, first, to explore metaphorical recursiveness in Yaminahua, i.e. the latter’s folding of the common binary structure: {(x) things + (y) words} into the threefold scheme: (A) things + (B) external analogies + (C) internal metaphors, as displaying a multi-iconic semiotic system of the type: A ≈ [B] ≈ C, which is finally reduced to a twofold indexical system: A ← [B], contra Graham Townsley’s dismissal of semiotic theory as being of no relevance in contrast to cognitive construction. And, secondly, to show that within the traditional Yaminahua worldview animism, totemism, and analogism, which Philippe Descola has famously described as alternative ontologies, not only coexist but also structurally intertwined in a complex ternary system supportive, on the one hand, of the basal binary logic characteristic of most Amazonian ontologies, and correlative, on the other hand, to the fourfold intersecting structure that has traditionally made possible the integration of all the Yaminahua people into the four dimensions of space, time, society, and the cosmos
From Worlds of Possibles to Possible Worlds: Or, Dionysus and Apollo after Nihilism
Is it possible to simultaneously escape the regime of authoritarian overdetermination distinctive of all modern totalitarianisms and the regime of anarchic underdetermination characteristic, in turn, of all hypermodern nihilisms? To what extent is Nietzsche’s philosophy responsible for having transformed such conceptual polarity in a frozen dichotomy? And to what extent are Heidegger and Deleuze, despite their differences, responsible for having rendered it all the more inescapable with their subtractive thought, which tends to privilege the possible over being? How, then, should we fancy the Otherwise – the otherwise of today’s unworld? Dionysus and Apollo, this paper argues, provide a tool for it in their quality of conceptual personae through whose interplay “elicitation” and “containment” (Roy Wagner) regain their lost reciprocity against any Subject/Object divide. It thus combines a philosophy-of-mythology approach with a neo-structuralist critique of contemporary thought in dialogue with current anthropological theory in an attempt to figure out the minimal structure of any worlding process. Additionally, it engages in a discussion on the nature and limits of cosmopolitics vis-à-vis nihilism’s accomplishment and it underlines the benefits of embracing a rigorously extra-modern type of logic, neither machinic nor demonstrative nor illuminative, but chiastic
