Xanthoria parietina as a biomonitor of airborne heavy metal pollution in forest sites in the North East of Morocco

Xanthoria parietina, common foliose lichen, growing in its natural habitat, was analysed for the concentration of five heavy metals (Fe, Cr, Zn, Pb and Cu) from different forest sites of North East of Morocco (Kenitra, Sidi Boughaba, Mkhinza, Ceinture Verte near Temara city, Skhirate, Bouznika and Mohammedia). The quantification was carried out by inductively coupled plasma - atomic emission spectrometry (ICP-AES). Results were highly significant p<0,001. The concentration of metals is correlated with the vehicular activity and urbanization. The total metal concentration is highest at the Kenitra area, followed by Ceinture Verte site near Temara city, which experience heavy traffic throughout the year. Scanning electron microscopy (SEM) of particulate matter on lichen of Xanthoria parietina was assessed as a complementary technique to wet chemical analysis for source apportionment of airborne contaminant. Analysis revealed high level of Cu, Cr, Zn and Pb in samples near roads.  

Narratives Around Iberian Culture at Valencia Museums and Archaeological Sites: From Official Discourses to Social Perceptions

Museums and archaeological sites are considered the most authoritative places for talking about the past and the heritage from a scientific perspective. In fact, visitors assume their discourses as reliable and indisputable. In spite of that, professionals of archaeology must critically analyse the production of narratives at heritage sites, since they often reflect social, political and identity issues related to the present-day realities. The aim of this paper is to study official and popular discourses about the Iberian culture (Iron Age) collected in museums and archaeological sites from Valencia region.

Biomonitoring of air pollutants by using lichens (Evernia prunastri) in areas between Kenitra and Mohammedia cities in Morocco.

In this study, Evernia prunastri, a lichen growing in its natural habitat in Morocco was analysed for the concentration of five heavy metals (Fe, Pb, Zn, Cu and Cr) from eleven sites between Kenitra and Mohammedia cities. The control site was Dar Essalam, an isolated area with low traffic density and dense vegetation. In the investigated areas, the concentration of heavy metals was correlated with vehicular traffic, industrial activity and urbanization. The total metal concentration was highest in Sidi Yahya, followed by Mohammedia and Bouznika. The coefficient of variation was higher for Pb and lower for Cu, Zn and Fe. The concentrations of most heavy metals in the thalli differed significantly between sites (p<0.01). Principal component analysis (PCA) revealed a significant correlation between heavy metal accumulation and atmospheric purity index. This study demonstrated also that the factors most strongly affecting the lichen flora were traffic density, the petroleum industry and paper factories in these areas. Overall, these results suggest that the index of atmospheric purity and assessment of heavy metals in lichen thalli are good indicators of the air quality at the studied sites.

El apoyo a la investigación en las bibliotecas universitarias españolas

Los cambios sufridos por los modelos de comunicación científica hacen que las bibliotecas universitarias se vean obligadas a dar nuevos servicios. Para adecuarse al investigador los bibliotecarios están desarrollando habilidades, colaborando con cada vez más estamentos y sustentando el acceso abierto. Apoyándose en una lista de posibles servicios, basada en la literatura especializada, este trabajo pretende cuantificar y evaluar el apoyo a la investigación desde las bibliotecas universitarias españolas. El sondeo demuestra la aparición de nuevos servicios e infraestructuras. Pero estas asistencias no suelen sistematizarse, difundirse ni evaluarse. Y, por otra parte, las consecuentes inversiones en personal y TIC han generado una brecha entre universidades

A methodological framework for studying policy coherence for development

The purpose of this article is to develop a methodological framework for analyzing Policy Coherence for Development (PCD). With this goal, we analyze different views of PCD in order to establish a comprehensive approach of Coherence adapted to globalization process. In this context, the article proposes a methodological framework based on four dimensions of analysis in CPD. In each dimen-sion, we set the areas and actors to investigate and we put forward research questions that could be use as a guide for a comprehensive approach to study PCD.

Scientifi c discourses on chronic pain without organic cause Incorporating gender perspective for pain resignifyng-repoliticizing

Chronic pain, without any organic or physical cause (DC), which in psycho-medical terminology is known as fi bromyalgia, (FM), is diagnosed each year to a considerable number of women in capitalistic societies. Our main interest in the following paper is to go in depth in the elaboration of this symptom, its treatment and the psychosocial effects, both in the social order as well as in the lives of the people who suffer from it. Our main goal in the following paper is to look deeper in the elaboration (conceptualization) of this symptom, its treatment and psychological affects, both in the social order as well as in the lives of the people who suffer from it, we are using linked speeches in Spanish magazines publications. The result has been the emergence of three hegemonic discourse positions: One position “scientist”, one “therapeutic of the conformity” position and one “economic and legalistic” position. Each of these has a specifi c feature, but on the whole, is enhanced, producing effects such as the absence of social context to explain the disease; disregard of gender differences in the management and treatment; the instrumentalization of pain to legitimize their practices and the subjection of women to the “psycho-biomedical” paradigm. In that way, a new signifi cance and politicization of the concept of pain is proposed.

Citizenship training in school from the perspective of future primary education teachers

The aim of this paper is to recognize the images that prospective elementary school teachers have about citizenship and citizenship education in school. The qualitative methodology with an ethnographic approach is used for that deep interview of ethnographic kind and analysis of institutional documents, for example, curricula, course syllabus and graduated profi le. The revision of documents helps to a better understanding of discourses. The analysis of the corpus obtained after the application of the paradigm of codifi cation proposed in the established theory. As the principal fi ndings we way point out that the concept of citizens that is common among prospective elementary school teachers is reduced to the school environment because they consider that the promotion of citizenship helps to the incorporation of children to society, thus reproducing a propaedeutic view of education.
