Welche Praxis nach der postkolonialen Kritik? Human- und physisch-geographische Feldforschung aus übersetzungstheoretischer Perspektive
2018
Abstract. After the postcolonial critique, dealing with the power of speaking and self-reflexivity belong to the great challenges of academic work. In this article, we derive the necessity to accept these challenges from our own projects and discuss their practical consequences as well as the difficulties of integrating them in development studies of human and physical geography. We argue that the propositions of postcolonial theory cannot be transferred in practice without contradictions. Therefore, we try to grasp these contradictions with the concept of translation. From the point of view of Translation Studies, contradictions do not necessarily lead to failure, but they have the potenti…
Emissivity mapping over urban areas using a classification-based approach: Application to the Dual-use European Security IR Experiment (DESIREX)
2012
Abstract In this work a methodology to provide an emissivity map of an urban area is presented. The methodology is applied to the city of Madrid (Spain) using data provided by the Airborne Hyperspectral Scanner (AHS) in 2008. From the data a classification map with twelve different urban materials was created. Each material was then characterized by a different emissivity, whose values were obtained from the application of the TES algorithm to in situ measurements and values extracted from the ASTER spectral library. This new emissivity map could be used as a basis for determining the temperature of the city and to understand the urban heat island effect in terms of spatial distribution and…
Use of geomorphological units to improve drainage network extraction from a DEM
1999
Abstract Drainage networks are one of the main elements characterizing basins, and network topology and geometry form the basis of many hydrological and geomorphological models ( eg Geomorphological Unitary Hydrograph). The identification and manual delineation of channel networks from maps or aerial photographs requires much time and effort. In the last two decades, algorithms and procedures for automated extraction of drainage networks from digital elevation data have been developed and implemented in many specialized software applications. Nevertheless, automatically delineated channel networks do not always show close agreement with manually delineated networks. This paper describes a c…
Rilievo ed elaborazione di dati laser acquisiti con sistemi MMS in un parco urbano
2013
Questo articolo riassume l'esperienza acquisita tra il 2012 e il 2013 dal Dipartimento di Ingegneria Civile, Ambientale, Aerospaziale e dei Materiali dell'Università degli Studi di Palermo per l'indagine integrata del Parco Ninni Cassarà a Palermo, Italia, e la successiva sperimentazione di metodi, strumenti e tecniche basate su ricerche in corso, per quanto riguarda l'acquisizione e l'elaborazione dei dati GNSS e laser Scanner. Il lavoro è stato affrontato al fine di selezionare le tecniche meno costose e veloci da applicare in fase di acquisizione. Dopo la prima monumentazione di sedici punti di controllo distribuiti all'interno del sito e rilevati con ricevitori GNSS, la è stata pianific…
Il ducato di Filippo Maria Visconti, 1412-1447. Economia, politica, cultura
2016
ITALIANO: La dominazione di Filippo Maria Visconti in Lombardia (1412-1447) fu il risultato di un tentativo, solo parzialmente riuscito, di ricomporre i vasti territori gia dominati dal primo duca, Giangaleazzo Visconti. Per trentacinque anni, il terzo duca di Milano governo uno stato ampio, ricco e prospero, ne rafforzo le istituzioni, coltivo alte ambizioni monarchiche e proclamo idee di pace, di concordia e di giustizia. L’uso delle armi e della diplomazia e il serrato confronto con gli attori politici, sociali ed economici del dominio furono gli strumenti adottati per rafforzare e consolidare il dominio ducale. Gli autori di questo volume illustrano i modelli politici sottostanti all’es…
Revista iberoamericana de educación
2012
Título, resumen y palabras clave en español, portugués e inglés Monográfico con el título: "Didáctica de la Lengua y la Literatura" Resumen tomado de la publicación Se centra en la relación didáctica entre la gramática, entendida como reflexión sobre la lengua, y la mejora del uso lingüístico. Para ello, se aborda, en primer lugar, la finalidad de la enseñanza de las lenguas en los currículos escolares y el papel que se atribuye a la reflexión gramatical en ellos. A continuación, se muestra la importancia de las investigaciones sobre la actividad metalingüística de los hablantes para un planteamiento de la gramática en función del uso. Por último, se revisan algunas vías exploradas por la i…
Using Landsat TM and field data to produce maps of predicted bird densities in Latvian farmland
2005
Models of farmland bird population densities established from field surveys were applied to classified satellite data for mapping of predicted bird numbers. The field survey system was based upon point counts of birds and descriptions of their habitat within a 200 m radius. The relationship between birds and habitats was analysed by means of multiple regression analysis. The resulting regression models were coded into classified Landsat Enhanced Thematic Mapper (ETM+) data which had similar land cover/use classes as the field observation data. With the use of a circular 200 m radius moving window approach, simulated maps of predicted bird population densities were produced. The results indi…
Spatio-temporal cluster detection of chickenpox in Valencia, Spain in the period 2008-2012.
2015
Chickenpox is a highly contagious airborne disease caused by <em>Varicella zoster</em>, which affects nearly all non-immune children worldwide with an annual incidence estimated at 80-90 million cases. To analyze the spatiotemporal pattern of the chickenpox incidence in the city of Valencia, Spain two complementary statistical approaches were used. First, we evaluated the existence of clusters and spatio-temporal interaction; secondly, we used this information to find the locations of the spatio-temporal clusters via the space-time permutation model. The first method used detects any aggregation in our data but does not provide the spatial and temporal information. The second me…
Justicia ecológica: la propuesta del Papa Francisco frente a la crisis ambiental
2016
La crisis ecológica ha sido objeto de la atención prioritaria por parte del papa Francisco desde el inicio de su pontificado en 2013 hasta el momento. En mayo de 2015 publicó la Encíclica Laudato si’ sobre el cuidado de la casa común, la primera en el magisterio social de la Iglesia católica íntegramente dedicada a las relaciones del ser humano con la naturaleza. Este trabajo trata de sintetizar los aspectos fundamentales de la enseñanza del papa Francisco sobre la crisis ecológica, que constituye una denuncia profética de la degradación ambiental y la exclusión social que el ser humano está llevando a cabo, y que debe ser combatida con urgencia mediante la conversión personal y la transfor…
