Disciplines and thematics of scientific research in police training (1988-2012)
2014
Purpose – The purpose of this paper is to analyze the disciplines and thematic study of scientific production in police training over the period 1988-2012. Design/methodology/approach – Introduction and homogenization of keywords and assigning of descriptors to documents, thematic categorization of journals and, analysis of indicators of productivity and relationship of descriptors and thematic areas has been the used methodology. Findings – Totally, 59 different descriptors of a total of 585 assigned to the 182 articles that were published in 95 journals belonging into 20 different subject areas have been identified. The most frequent descriptors are “skills,” “management development” and…

Land surface temperature retrieval from LANDSAT TM 5
2004
In this paper, three methods to retrieve the land surface temperature (LST) from thermal infrared data supplied by band 6 of the Thematic Mapper (TM) sensor onboard the Landsat 5 satellite are compared. The first of them lies on the estimation of the land surface temperature from the radiative transfer equation using in situ radiosounding data. The others two are the mono-window algorithm developed by Qin et al. [International Journal of Remote Sensing 22 (2001) 3719] and the single-channel algorithm developed by Jime´nez-Mun˜oz and Sobrino [Journal of Geophysical Research 108 (2003)]. The land surface emissivity (LSE) values needed in order to apply these methods have been estimated from a…
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 …
Enhancing visual literacy through interpretation of photo-genres: toward a genre typology of journalistic photographs
2016
ABSTRACTAlthough genre is one of the most extensively employed concepts in various disciplines, only a few attempts have been made to classify images in the press, providing either a palette of thematic categories similar to those of photography competitions or theory-based classifications, which often ignore certain types of photographs. In addition, no studies have suggested the genre typology as a tool for the interpretation of journalistic photographs. Based on a literature review and visual material analysis from the Polish daily Gazeta Wyborcza, this study compiles a typology that sets out four photo-genres: news photography, reportage photography, portrait photography and illustrativ…

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…
Multitemporal Unmixing of Medium-Spatial-Resolution Satellite Images: A Case Study Using MERIS Images for Land-Cover Mapping
2011
Data from current medium-spatial-resolution imaging spectroradiometers are used for land-cover mapping and land-cover change detection at regional to global scales. However, few landscapes are homogeneous at these scales, and this creates the so-called mixed-pixel problem. In this context, this study explores the use of the linear spectral mixture model to extract subpixel land-cover composition from medium-spatial-resolution data. In particular, a time series of MEdium Resolution Imaging Spectrometer (MERIS) full-resolution (FR; pixel size of 300 m) images acquired over The Netherlands is used to illustrate this study. The Netherlands was selected because of the following: 1) the fragmenta…
Vineyard design supported by GPS application
2021
The innovative technologies of precision agriculture offer nowadays new applications in line with the needs of the wine sector. In hillside viticulture, within the same plot there are areas with different physical and chemical characteristics (lying, pH, active limestone, nutrients, etc.). This variability consequently influences the vigor of the vine which translates into a different production per single plant in terms of both yield and quality of the grapes. The aim of this study was to realize geo-referenced thematic maps by GPS application on a hilly plot covering about 6 hectares to be planted in a hedgerow trained vineyard for the production of quality grapes. The experimental tests …
