Web 2.0 Goes Mobile: Motivations and Barriers of Mobile Social Networks Use in Spain
2012
Mobile social networking sites have become one of the fastest growing Web 2.0 services worldwide both in developing and developed countries and have a major interest for the information systems research community. This chapter aims to give managers and students insight into the mobile social networking industry and the different drivers and barriers to mobile social networking sites adoption. The chapter’s specific goals are to: (i) Identify consumer segments more likely to adopt mobile social networking services; (ii) Analyze the perceived benefits and barriers that encourage/discourage the adoption of mobile social networking services; (iii) Provide empirical research on the Spanish marke…
Spatial Bayesian Modeling Applied to the Surveys of Xylella fastidiosa in Alicante (Spain) and Apulia (Italy)
2020
The plant-pathogenic bacterium Xylella fastidiosa was first reported in Europe in 2013, in the province of Lecce, Italy, where extensive areas were affected by the olive quick decline syndrome, caused by the subsp. pauca. In Alicante, Spain, almond leaf scorch, caused by X. fastidiosa subsp. multiplex, was detected in 2017. The effects of climatic and spatial factors on the geographic distribution of X. fastidiosa in these two infested regions in Europe were studied. The presence/absence data of X. fastidiosa in the official surveys were analyzed using Bayesian hierarchical models through the integrated nested Laplace approximation (INLA) methodology. Climatic covariates were obtained from …
Modeling the Spatial Distribution of Xylella fastidiosa: A Nonstationary Approach with Dispersal Barriers
2022
Spatial species distribution models often assume isotropy and stationarity, implying that spatial dependence is direction-invariant and uniform throughout the study area. However, these assumptions are violated when dispersal barriers are present. Despite this, the issue of nonstationarity has been little explored in the context of plant health. The objective of this study was to evaluate the influence of barriers in the distribution of Xylella fastidiosa in the demarcated area in Alicante, Spain. Occurrence data from 2018 were analyzed through spatial Bayesian hierarchical models. The stationary model, illustrating a scenario without control interventions or geographical features, was com…
Comparaison de deux méthodes de correction atmosphérique des données thermiques de Landsat TM
1996
The high resolution of Landsat Thematic Mapper (TM) thermal infrared data can be interesting in applications such as energy balance and crop water stress studies. However, surface temperature measurements are strongly affected by atmospheric effects, particularly by water vapour absorption, therefore a correction method is absolutely necessary. The impossibility of applying a split-window equation and the difficulty of having temporarily coincident radiosondes produce a slight use of Landsat TM data to obtain surface temperature. Vidal et al. show that in a zone with homogeneous climatic conditions, atmospheric correction can be evaluated by using energy balance equation and standard meteor…
Global equatorial variability of 850 and 200 hPa zonal winds from rawinsondes between 1963 and 1989
1995
The longitude-height-time variability of 3-month averaged zonal wind anomalies at 850 and 200 hPa over the equatorial area (5{degrees}N-5{degrees}S) is analyzed using a three-dimensional dataset constructed from rawinsonde data (1963-1989). The first mode, closely related to the Southern Oscillation Index, suggests a strong vertical coupling associated with a horizontal out-of-phase pattern between the central/western Pacific and the remainder of the equatorial belt. The vertical coupling appears to be phase-locked to the annual cycle with strongest intensities found over South America and near the maritime continent early in the calendar year and over the Pacific basin and Africa during th…
A case study on the formation and evolution of ice supersaturation in the vicinity of a warm conveyor belt\'s outflow region
2005
A case study is presented on the formation and evolution of an ice-supersaturated region (ISSR) that was detected by a radiosonde in NE Germany at 06:00 UTC 29 November 2000. The ISSR was situated in the vicinity of the outflow region of a warm conveyor belt associated with an intense event of cyclogenesis in the eastern North Atlantic. Using ECMWF analyses and trajectory calculations it is determined when the air parcels became supersaturated and later subsaturated again. In the case considered, the state of air parcel supersaturation can last for longer than 24h. The ISSR was unusually thick: while the mean vertical extension of ISSRs in NE Germany is about 500m, the one investigated here…
Raw material procurement and selection in Southeast Iberia’s early metallurgy
2020
The role of metallurgy in the Copper Age communities of the Iberian Southeast is a recurrent question of archaeological research in western Europe. Based on lead isotope and trace element analyses of archaeometallurgical remains, this paper addresses the territorial organisation of metallurgical production during the Copper Age (3100-2200 cal BC) in the Vera Basin (Almería, Spain), the region with the earliest metallurgical evidence in western Europe. This paper comprises the study of materials from the three main settlements with metallurgical activity in the area (Las Pilas, Santa Bárbara and Almizaraque), as well as some metal objects from these and other sites (La Encantada I, Loma…
La secuencia didáctica: un instrumento para escribir textos en educación infantil
2019
espanolSon muchos los trabajos que muestran preocupacion por la ensenanza de la lengua escrita en los primeros anos escolares. Este tema ha sido motivo de debate durante decadas. Si bien hace algun tiempo el foco de la ensenanza de la escritura inicial se focalizaba en el uso de diferentes metodos (sinteticos o analiticos principalmente), desde hace unas decadas se situa en los planteamientos socioculturales o socioconstructivistas. Se sabe actualmente que uno de los factores clave para el aprendizaje de la escritura es organizar su ensenanza desde una perspectiva funcional. El entorno social y las situaciones comunicativas son, por tanto, ejes fundamentales en la alfabetizacion inicial. Co…

Factores determinantes del desempeño de las alianzas estratégicas: hallazgos en los consorcios del sector cooperativo costarricense
2015
El tema de los acuerdos de cooperación es relevante como una buena práctica en la dirección de empresas, pero al mismo tiempo su aplicación exitosa no es sencilla, y no está exenta de fracaso. Se hace necesario entonces desarrollar esfuerzos como esta investigación, que pretende aportar al conocimiento sobre las alianzas estratégicas, específicamente en relación con los factores conducentes al buen desempeño de las mismas. Empleamos una metodología de investigación con enfoque cuantitativo, en la cual utilizamos ecuaciones estructurales, por medio de la técnica de análisis por mínimos cuadrados parciales, apropiada en etapas iniciales del desarrollo de teorías, cuando un modelo conceptual y…
