Propositions pour une littérature d'investigation
2017
International audience; Le temps semble à l’alliance de la littérature et des sciences sociales. Mais les modalités en sont encore incertaines. Au lieu de considérer l’anthropologie comme une forme de littérature, on peut envisager la littérature comme une enquête. Cette « littérature d’investigation » se donne notamment pour objectif de documenter des formes de vie et de monter des dispositifs rendant compte d’aspects inaperçus de phénomènes sociaux. Elle occupe ainsi une position intermédiaire : elle se ménage à la fois une liberté et une créativité relatives vis-à-vis des protocoles d’enquête propres aux sciences sociales et une certaine méfiance pour un sens trop révérencieux envers la …
Drone images versus terrain images in advertisements: Images’ verticality effects and the mediating role of mental simulation on attitude towards the…
2018
Over the past decade, new techniques have been developed to entice and persuade advertisement viewers. One technique, which has grown in popularity, is the use of drones to capture images within an...
In glacial environments beyond glacial terrains: Human eco-dynamics in late Pleistocene Mediterranean Iberia
2013
The Iberian Peninsula south of the Ebro River enjoyed one of the mildest climates of Pleistocene Europe, but still experienced significant and rapid environmental shifts caused by global climate regimes. We examine the interplay between technological, social, and land-use dynamics as culturally mediated responses to climate change outside the periglacial zone. We combine information from excavated sites across eastern and southeastern Spain with systematic survey data from an intensive study area within this larger region to examine Upper Paleolithic behavioral adaptations to the environmental shifts of the late Pleistocene (late MIS-3 through MIS-2). We define indexes that serve as proxies…
Metamorphic History of Gneiss Terrains
1990
The local metamorphic history is an essential topic in the study of high-grade gneiss terrains. This chapter only deals with those aspects of the metamorphic history that can be studied in the field. We will briefly outline terminology, the methods which can be applied, and the difficulties involved. For more information we refer to textbooks such as Miyashiro (1975), Winkler (1976), Mason (1981), Best (1982), Vernon (1983), Spry (1986), Yardley (1989) and to the references given in the text.
Implementation of non-local boundary layer schemes in the Regional Atmospheric Modeling System and its impact on simulated mesoscale circulations
2016
This paper proposes the implementation of different non-local Planetary Boundary Layer schemes within the Regional Atmospheric Modeling System (RAMS) model. The two selected PBL parameterizations are the Medium-Range Forecast (MRF) PBL and its updated version, known as the Yonsei University (YSU) PBL. YSU is a first-order scheme that uses non-local eddy diffusivity coefficients to compute turbulent fluxes. It is based on the MRF, and improves it with an explicit treatment of the entrainment. With the aim of evaluating the RAMS results for these PBL parameterizations, a series of numerical simulations have been performed and contrasted with the results obtained using the Mellor and Yamada (M…
Sensitivity analysis on the relationship between vegetation growth and multi-polarized radar data
2009
Spatially distributed soil moisture is required for watershed applications such as drought and flood prediction, crop irrigation scheduling, etc. In particular, an accurate assessment of the spatial and temporal variation of soil moisture is necessary to improve the predictive capability of runoff models, and for improving and validating hydrological processes forecasting. In recent years, several models have been developed in order to retrieve soil moisture using RADAR data. However, these models need precise prior knowledge about surface roughness. Within this framework, the present research aims to investigate the capabilities of multi polarimetric RADAR images to overcome the use of in …
Prediction of debris-avalanches and -flows triggered by a tropical storm by using a stochastic approach: An application to the events occurred in Moc…
2019
Abstract Landslides are among the most dangerous natural processes. Debris avalanches and debris flows in particular have often caused casualties and severe damage to infrastructures in a wide range of environments. The assessment of susceptibility to these phenomena may help policy makers in mitigating the associated risk and thus it has attracted special attention in the last decades. In this experiment, we assessed susceptibility to debris-avalanche and -flow landslides by using a stochastic approach. Two different modeling techniques were employed: i) Multivariate Adaptive Regression Splines (MARS) and ii) Logistic Regression (LR). Both MARS and LR allow for calculating the probability …
Assessment of susceptibility to earth-flow landslide using logistic regression and multivariate adaptive regression splines: A case of the Belice Riv…
2015
Abstract In this paper, terrain susceptibility to earth-flow occurrence was evaluated by using geographic information systems (GIS) and two statistical methods: Logistic regression (LR) and multivariate adaptive regression splines (MARS). LR has been already demonstrated to provide reliable predictions of earth-flow occurrence, whereas MARS, as far as we know, has never been used to generate earth-flow susceptibility models. The experiment was carried out in a basin of western Sicily (Italy), which extends for 51 km 2 and is severely affected by earth-flows. In total, we mapped 1376 earth-flows, covering an area of 4.59 km 2 . To explore the effect of pre-failure topography on earth-flow sp…
5-6 gadus vecu bērnu prasmes orientēties apvidū veidošanās pirmsskolas izglītības iestādē
2019
Maģistra darba tēma ir “ 5-6 gadus vecu bērnu prasmes orientēties apvidū veidošanās pirmsskolas izglītības iestādē”. Darba mērķis ir izpētīt 5-6 gadus vecu bērnu prasmes orientēties apvidū veidošanos. Darbs sastāv no 50 lappusēm, 4 nodaļām, kas ietver sevī 7 attēlus, 12 tabulas, izmantotās literatūras sarakstu ar 41 vienību un 2 pielikumus. Gan Skola 2030, gan VISC (Valsts izglītības un satura centrs) veidotajās pirmsskolas izglītības programmās ir minēts, ka, pirmsskolu beidzot, bērnam ir jāprot orientēties telpā un plaknē. Orientēšanās apvidū netiek atsevišķi izdalīta, kaut gan tā ir tikpat svarīga kā orientēšanās telpā un plaknē. 5 – 6 gadi ir vecums, kad bērnus sāk gatavot skolai, kur o…
Validation of daily global solar irradiation images from MSG over Spain
2013
Abstract Daily irradiation images over Spain – area that embraces a highly heterogeneous landscape, climatic conditions and relief – are calculated from the down-welling surface short-wave radiation flux (DSSF) product derived from the MSG SEVIRI images. Their analysis and validation is carried out using two different station networks along the year 2008. The first network covers the peninsular Spain and Balearic islands. A denser one, covering the Catalonian territory and including many stations located in rugged terrain, is found useful to assess the elevation correction to be applied to the images. The statistics from the validation using the first network shows a relative mean bias of a…
