Cloud-based interactive susceptibility modeling of gully erosion in Google Earth Engine
2022
The gully erosion susceptibility literature is largely dominated by contributions focused on model comparison. This has led to prioritize certain aspects and leave others underdeveloped as compared to other natural hazard applications. For instance, in gully erosion data-driven modeling most studies use different platforms when it comes to data management, modeling and conversion into predictive maps. This in turn has limited the scope to catchment-scales. In this manuscript, we opt to propose a tool where the whole modeling procedure is unified within the same cloud computing system, allowing one to get rid of potential errors caused by input/output operations but also to extend the study …
Parenting Styles and Children’s Emotional Development during the First Grade: The Moderating Role of Child Temperament
2015
This study investigated the associations between parenting styles (affection, behavioral control, and psychological control) and children’s emotional development (emotion expression) during the first grade of primary school, and the moderating role of children’s temperament (easy, difficult, and inhibited) in these associations. Mothers and fathers of 152 children responded to a questionnaire concerning their parenting styles and their child’s temperament at the beginning of their child’s first grade (Time 1). They also filled in a structured diary questionnaire concerning their child’s negative and positive emotions over seven successive days (diary) at the beginning (Time 1) and at the en…
Improving transferability strategies for debris flow susceptibility assessment: Application to the Saponara and Itala catchments (Messina, Italy)
2017
Abstract Debris flows can be described as rapid gravity-induced mass movements controlled by topography that are usually triggered as a consequence of storm rainfalls. One of the problems when dealing with debris flow recognition is that the eroded surface is usually very shallow and it can be masked by vegetation or fast weathering as early as one-two years after a landslide has occurred. For this reason, even areas that are highly susceptible to debris flow might suffer of a lack of reliable landslide inventories. However, these inventories are necessary for susceptibility assessment. Model transferability, which is based on calibrating a susceptibility model in a training area in order t…
Social withdrawal in children moderates the association between parenting styles and the children's own socioemotional development.
2014
Background: Social withdrawal in early childhood is a risk factor for later socioemotional difficulties. This study examined the joint effects of children’s social withdrawal and mothers’ and fathers’ parenting styles on children’s socioemotional development. Based on diatheses-stress, vantage sensitivity, and differential susceptibility models, socially withdrawn children were assumed to be more prone to parental influences than others. Methods: Teachers rated 314 children on prosocial skills, and internalizing and externalizing behaviors at three points in time between grades 1–3. Mothers (n = 279) and fathers (n = 182) filled in questionnaires measuring their affection, and their behavio…
A GIS-based approach for gully erosion susceptibility modelling: a test in Sicily, Italy
2013
The aim of this study is to analyze the susceptibility conditions to gully erosion phenomena in the Magazzolo River basin and to test a method that allows for driving the factors selection. The study area is one of the largest (225 km2) watershed of southern Sicily and it is mostly characterized by gentle slopes carved into clayey and evaporitic sediments, except for the northern sector where carbonatic rocks give rise to steep slopes. In order to obtain a quantitative evaluation of gully erosion susceptibility, statistical relationships between the spatial distributions of gullies affecting the area and a set of twelve environmental variables were analyzed. Stereoscopic analysis of aerial …
The joint effects of parenting styles and the child's temperamental characteristics in children's social-emotional development
2016
This research examined the joint effects of parenting and the temperamental characteristics of children on their social-emotional development during their early school years. Three studies, focusing on different aspects of social-emotional development as well as on different temperamental characteristics, were carried out. The first study investigated the extent to which mothers' and fathers' parenting styles differently impact their children's social-emotional development, based on the children's tendency to show signs of social withdrawal. The second study focused on the different impacts of parenting styles on children's emotional expression, depending on the children's temperament type.…
Factor selection procedures in a Google Earthtm aided landslide susceptibility model: application to the Beiro river basin (Spain)
2011
A procedure to select the controlling factors connected to the slope instability has been defined. It allowed to assess the landslide susceptibility in the Rio Beiro basin (about 10 km2) over the north-eastern area of the city of Granada (Spain). Field and remote (Google EarthTM) recognition techniques allowed to generate a landslide inventory consisting in 127 phenomena. Univariate tests, using both association coefficients and validation results of single parameter susceptibility models, allowed to select among 15 controlling factors the ones that resulted as good predictor variables; these have been combined for unique conditions analysis and susceptibility maps were finally prepared. In…
