"A collection of articles on the use of analytical methods in studies concerning geospatial analysis and data integration for cultural heritage evaluation. This volume is presented as a collection of self-contained articles providing easy access to suit the requirements and interests of individual readers. In order to be self-contained, each article is prefaced by a general introduction which briefly provides the theoretical principles and the general background of the discussed methods or techniques."--Publisher's website

El ODS4 procura garantizar la educación inclusiva, pero alcanzar este objetivo es problemático frente a la homogeneización biocultural. Examinamos el rol de la educación en la homogeneización, al promover una representación sesgada de la biodiversidad, según un análisis del contenido visual de los textos escolares en la educación básica de México y Chile. Los resultados muestran sesgos taxonómicos a partir de un limitado corpus de imágenes que no representan la biodiversidad singular. En México registramos 2,5 animales por cada planta mostrada, de los cuales el 74% fueron registros de especies nativas. En Chile, la proporción animal y vegetal fue de aproximadamente 1:1, de los cuales el 68% fueron registros de especies exóticas. Discutimos estos sesgos respecto a una transformación educativa que sirva mejor a la Agenda 2030.

AbstractThis paper explores how research advisory groups can be a vehicle for youth activism. It draws on our experiences with young activists, aged 15–26 years, in India and Brazil, who were advisors on a research project focused on youth livelihoods in cities. These young people played a vital role in supporting youth researchers, identifying research themes and developing engagement and advocacy strategies. Through this paper, we explore how the Youth Expert Group advisory model evolved differently in each location and examine how these were shaped by the context, the 'adult' research team and the youth activists themselves. A critically reflexive response in intergenerational partnership is essential to support youth activists in research activities.

So far no effective field applicable therapeutic strategy exists to combat the severe diseases associated to X. fastidiosa. Therefore, various experimental applications to seek for a sustainable approach for the mitigation of the impact of the infections on olive trees were explored. In 2015-2016, four field trials were set in the infected area in southern Italy: (i) trial 1 consisted of an olive grove with medium to high incidence of disease symptoms; (ii) trials 2 and 3 consisted of olive groves with very low incidence of infected and symptomatic trees and (iii) trial 4 was a new plantation with 3-years old Xylella-free olive plants. Applications included (i) different elicitors of plant resistance (fosetyl aluminium, acibenzolar-S-methyl, COS-OGA, σ–β Hairpin proteins, cerevisanae) and (ii) Nacetylcysteine (NAC), a mucolytic agent previously showed to have a beneficial impact in reducing symptoms associated to X. fastidiosa in citrus (1). Periodic surveys included (i) sampling for laboratory tests to determine the incidence of the infections; (ii) symptom scoring using 0-5 empirical scale of severity. The overall results showed that only the treatments with NAC, through endotherapy and/or complexed to organic substances added to the soil, determined a noticeable amelioration of the symptoms. None of the elicitors produced any measurable positive impact on the diseased trees. These preliminary encouraging results, prompted for further targeted experiments currently ongoing. ; Acknowledgment This work has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement N. 635646 "Pest Organisms Threatening Europe POnTE" and from the Project T.A.P.A.S.S.
