Predicting depositional areas of landslide susceptibility comparing four datasets extracted from landslide area: a case of study after rainfall-induc…
Hurricane Ida and low-pressure system 96E crossed Central American countries in 2009. However, in El Salvador, the torrential rainfalls caused many flooding and landslides. As a result, over 200 causalities and the destruction of several villages, and bridges occurred along the mountain slopes. The remote analysis allowed us to prepare an inventory of landslides that occurred after the Hurricane in a basin located in the northern part of Ilopango Caldera. Five groups of data sets were created using selected pixels of each landslide area in order to evaluate the capacity to predict the lowest and the entire landslide area. Multivariate Adaptive Regression Splines (MARS) were employed to mode…
Emprendimiento en personas con discapacidad. Un diagnóstico a través de la técnica de grupo nominal
2018
The aim of this work is to identify the dimensions and aspects that foster and / or restrict the entrepreneurial action of disabled people from a qualitative methodological perspective. The analysis was carried out by means of the nominal group technique. As a result of the analysis, this work proposes, through the work done with disabled people, a set of interventions that will reduce barriers and foster the entrepreneurship of such vulnerable group
Mapping Susceptibility to Debris Flows Triggered by Tropical Storms: A Case Study of the San Vicente Volcano Area (El Salvador, CA)
2021
In this study, an inventory of storm-triggered debris flows performed in the area of the San Vicente volcano (El Salvador, CA) was used to calibrate predictive models and prepare a landslide susceptibility map. The storm event struck the area in November 2009 as the result of the simultaneous action of low-pressure system 96E and Hurricane Ida. Multivariate Adaptive Regression Splines (MARS) was employed to model the relationships between a set of environmental variables and the locations of the debris flows. Validation of the models was performed by splitting 100 random samples of event and non-event 10 m pixels into training and test subsets. The validation results revealed an excellent (…
Evaluation of debris flow susceptibility in El Salvador (CA): a comparison between Multivariate Adaptive Regression Splines (MARS) and Binary Logisti…
2018
In the studies of landslide susceptibility assessment, which have been developed in recent years, statistical methods have increasingly been applied. Among all, the BLR (Binary Logistic Regression) certainly finds a more extensive application while MARS (Multivariate Adaptive Regression Splines), despite the good performance and the innovation of the strategies of analysis, only recently began to be employed as a statistical tool for predicting landslide occurrence. The purpose of this research was to evaluate the predictive performance and identify possible drawbacks of the two statistical techniques mentioned above, focusing in particular on the prediction of debris flows. To this aim, an…
Economic Theory and its History
2016
This collection of essays is a tribute to Neri Salvadori, the man and scholar, teacher and friend, whom the scientific community owes important works in the tradition of Piero Sraffa’s revival of the classical economists’ approach to the problems of value, income distribution, capital accumulation, technical progress, scarce natural resources, economic development and growth. The essays in this book have all been freshly written and contain original work with novel ideas in the areas mentioned.
Introduction
2016
This collection of essays is a tribute to Neri Salvadori, the man and scholar, teacher and friend, whom the scientific community owes important works in the tradition of Piero Sraffa’s revival of the classical economists’ approach to the problems of value, income distribution, capital accumulation, technical progress, scarce natural resources, economic development and growth. The essays in this book have all been freshly written and contain original work with novel ideas in the areas mentioned. In this introduction we first summarize briefly Neri Salvadori’s academic career, his work and his intellectual and organisational activities and then provide a short overview of the essays collected…
Predicting the landslides triggered by the 2009 96E/Ida tropical storms in the Ilopango caldera area (El Salvador, CA): optimizing MARS-based model b…
2019
The main topic of this research was to evaluate the effect in the performance of stochastic landslide susceptibility models, produced by differences between the triggering events of the calibration and validation datasets. In the Caldera Ilopango area (El Salvador), MARS (multivariate adaptive regression splines)-based susceptibility modeling was applied using a set of physical–environmental predictors and two remotely recognized landslide inventories: one dated at 2003 (1503 landslides), which was the result of a normal rainfall season, and one which was produced by the combined effect of the Ida hurricane and the 96E tropical depression in 2009 (2237 landslides). Both the event inventorie…
Il Salvador si avvia a pianificare città e territori: un’esperienza pilota partecipativa a Santa Marta, a partire da un lungo lavoro psicologico
2015
Gli autori descrivono un caso di cooperazione allo sviluppo iniziato nel 2008 come intervento di Psicologi nel mondo, continuato anno dopo anno, generatore di una esperienza di pianificazione partecipativa a cura del Politecnico di Torino nel 2014. Le riflessioni teoriche sul rapporto interdisciplinare tra psicologia e pianificazione si ancorano a un caso studio locale, la piccola comunità di Santa Marta, mentre il Salvador spinge verso la pianificazione città e territori. The authors describe a case of cooperation that began in 2008 as an intervention of Psicologi nel mondo, continued year after year, generating an experience of participatory planning carried out by the Politecnico di Tori…
