SIG des Merveilles: analysing rock art distribution with a web cartographic platform

L. Costa, F. Djindjian, F. Giligny (eds.), Actes des 3èmes Journées d'Informatique et Archéologie de Paris, JIAP 2012International audienceThe Vallée des Merveilles (Valley of Marvels), in the Mercantour National Park (France), is a major place for studying the late Neolithic Age until the beginning of the Bronze Age: since the early 20th century, more than 4000 engraved rocks have been listed, representing 40,000 carvings. The Laboratoire Départemental du Lazaret has been studying these engravings for more than forty years: a large database describes the whole rocks and figures and is still filled with new findings. But such a large amount of data from a vast archaeological site needs efficient tools for its study, such as mapping the location of the rocks. Many improvements regarding the study of the carvings and their spatial distribution were made possible by the development of a web GIS: consulting the data is made easier and clearer with a web-mapping platform and specific tools. Filtering for choosing the data to display and automatically generated maps allow an overall view of the spatial distribution of the Marvels' engravings. Using both the IGN's Geoportal data and cartographic web libraries produced an efficient and complete web service for consulting and analyzing the engraved rocks of the Valley of Marvels. This one can be used for any area in the Mercantour Park, as long as new data are added to the databases

Design thinking, system thinking, Grounded Theory, and system dynamics modeling - An integrative methodology for social sciences and humanities

This paper concerns design thinking (Lawson, 1980), system thinking (systems theory) (von Bertalanffy, 1968), and system dynamics modeling as methodological platforms for analyzing large amounts of qualitative data and transforming it into quantitative mode. The aims of this article are to present an integral (mixed) research process including the design thinking process - a solution oriented approach applicable in the social sciences and humanities which enables to reveal causality in research on societal and behavioral issues. This integral approach is illustrated by an empirical pilot study from art/design-educational environment. © 2018 Eva Šviráková, Gabriel Bianchi, published by De Gruyter.Slovak research agency VEGA [2/0027/17

Demonios e imaginación en Giordano Bruno

With Giordano Bruno (1548-1600) we attend the recovery of Neoplatonic and Hermetic doctrines that lead to an animistic and dynamic understanding of nature, as well as an exaltation of man as who knows and acts on the world. In the context of a living and animated universe, Bruno needs mediations in the space between, on the one hand, the finite nature of man and, on the other hand, the infinite divinity explained in nature to support the magic theory of his Latin work. Accurately, the existence of demons in Neoplatonic systems comes to fulfill that purpose. I maintain that there is continuity between the demonological doctrine that Bruno presents in his Latin work and the metaphysics and cosmology of his Italian dialogues. This continuity is verified in the presence of two important philosophical categories of Bruneian thought which is in the demonology of De magia naturali (1590): the imagination and bonds. Thus, firstly, I will inquire about the reception of Neoplatonic doctrine in the demonology of the 15th and 16th centuries, from which Bruno develops the theoretical and philosophical framework of his demonological doctrine. Secondly, I will analyze the nature and function of the demons in De magia naturali and their relationship with the imagination and bonds in the Nolan philosophy.Con Giordano Bruno (1548-1600) asistimos a la recuperación de doctrinas neoplatónicas y herméticas que conducen a una comprensión animista y dinámica de la naturaleza, así como a una exaltación del hombre en tanto conoce y actúa sobre el mundo. En el contexto de un universo vivo y animado, Bruno necesita mediaciones en el espacio que hay entre, por un lado, la naturaleza finita del hombre y, por el otro, la divinidad infinita explicada en la naturaleza para fundamentar la teoría mágica de sus obras latinas. Precisamente, la existencia de los demonios en los sistemas neoplatónicos viene a cumplir con este propósito. Sostenemos que existe una continuidad entre la doctrina demonológica que Bruno presenta en su obra latina y la metafísica y cosmología de sus diálogos italianos. Esta continuidad se verifica en la presencia de dos categorías filosóficas importantes del pensamiento bruniano presente en la demonología del De magia naturali (1590): imaginación y vínculos. Así pues, en primer lugar, indagaremos la recepción de la doctrina neoplatónica en la demonología de los siglos XV y XVI, a partir de la cual Bruno desarrolla el marco teórico y filosófico de su doctrina demonológica. En segundo lugar, estudiaremos la naturaleza y función de los demonios en el De magia naturali y su relación con la imaginación y los vínculos en la filosofía del Nolano

On the Iwasawa-Taniguchi effect of radio-quiet AGN

The existence of an anti-correlation between the Equivalent Width (EW) of the neutral narrow core of the iron Kalpha emission line and the 2-10 keV luminosity (the so-called `X-ray Baldwin' or `Iwasawa-Taniguchi' effect) has been debated in the last years. We aim at testing this claim on the largest catalogue of radio quiet AGN high-quality X-ray spectra ever published. The final sample comprises 157 objects. We search for a relation of the iron line EW not only with the X-ray luminosity, but also with the Black Hole mass, the Eddington ratio and the cosmological distance. The data presented here were analyzed homogeneously, all spectra are from the same instrument and with high Signal-to-Noise Ratio. A linear censored fit on the EW versus 2-10 keV luminosity is highly significant and yields $\log(EW_{Fe}) = (1.73\pm0.03) + (-0.17\pm0.03) \log(L_{X,44})$, where $EW_{Fe}$ is the EW of the neutral iron Kalpha line in eV and $L_{x,44}$ is the 2-10 keV X-ray luminosity in units of $10^{44}$ erg s$^{-1}$. The anti-correlation with the Eddington ratio is also very significant, while no dependence of the iron EW on the BH mass is apparent.Comment: 4 pages, 4 figures, accepted for publication in Astronomy and Astrophysics Letter

Soberanía y estado de excepción en la polémica entre Walter Benjamin y Carl Schmitt

El propósito de este trabajo es presentar el debate entre dos autores, el filósofo Walter Benjamin y el jurista alemán Carl Schmitt, sobre dos conceptos que serán centrales en la teoría política contemporánea: el poder soberano y el estado de excepción. Para cumplir con nuestro propósito, nos basaremos en el desarrollo del tema que hace Giorgio Agamben en Estado de excepción (2003), quien rastrea los comienzos de este debate en el escrito benjaminiano Para una crítica de la violencia (1921), pasando por La Dictadura (1921) y Teología Política (1922) de Schmitt, hasta la obra sobre el Trauerspiel (1928) y las Tesis Sobre el concepto de la historia (1939-1940) de Benjamin.The purpose of this work is to present the debate between two authors, the philosopher Walter Benjamin and the German jurist Carl Schmitt, on two concepts that will be central to contemporary political theory: Sovereign Power and the State of Exception. To fulfill our purpose, we will follow the development of theme in Giorgio Agamben’s State of Exception (2003), who traces the beginnings of this debate in Benjamin’s Critique of Violence (1921), through Dictatorship (1921) and Political Theology (1922) by Schmitt, to the work on the Benjamin’s Trauerspiel (1928) and Theses On the Concept of History (1939-1940).Fil: Bianchi, Agustín Gabriel.

Impacto da geração solar fotovoltaica no preço de liquidação das diferenças em base horária

A implementação do Preço de Liquidação das Diferenças (PLD) em base horária está prevista para o mês de janeiro de 2021. Essa mudança é motivada principalmente pela crescente presença das fontes intermitentes de geração na matriz energética e pretende trazer modernidade ao Setor Elétrico Brasileiro, garantindo uma remuneração mais adequada ao novo padrão de geração de energia no Brasil. Nesse novo cenário de precificação, a fonte de geração solar fotovoltaica possui destaque devido ao seu período de maior injeção de potência corresponder ao período de maior consumo de energia no país. Esse fato aliado ao potencial que o Brasil possui devido a sua posição solar vantajosa sugere um aumento na participação da fonte solar fotovoltaica no parque de geração de energia brasileiro. Tendo isso em vista, este trabalho busca realizar uma análise exploratória sobre o impacto da geração solar fotovoltaica na formação do PLD em base horária. Analisando os padrões do PLD horário, da curva de carga sistêmica e da geração solar fotovoltaica de maneira qualitativa, este trabalho proporciona uma maior compreensão sobre a dinâmica do preço horário.The implementation of the Difference Settlement Price (PLD, of the Portuguese Preço de Liquidação das Diferenças) on an hourly basis is scheduled for January 2021. This change is mainly motivated by the increasing presence of intermittent sources of generation in the energy matrix and aims to bring modernity to the Brazilian Electric Sector, guaranteeing a remuneration best suited to the new energy generation standard in Brazil. In this new pricing scenario, the source of photovoltaic solar generation stands out due to its period of greatest power injection corresponding to the period of greatest energy consumption in the country. This fact, combined with the potential that Brazil has due to its advantageous solar position, suggests an increase in the participation of the photovoltaic solar source in the Brazilian power generation park. With this in mind, this paper seeks to carry out an exploratory analysis on the impact of solar photovoltaic generation on the formation of PLD on an hourly basis. Analyzing the patterns of the hourly PLD, the systemic load curve and solar photovoltaic generation in a qualitative way, this paper provides a greater understanding of the dynamics of the hourly price
