Revisiting the Epipalaeolithic-Neolithic Transition in the Extreme NW of Africa : The Latest Results of the Chronological Sequence of the Cave of Kaf…

2021

[EN] This study focuses on the chronostratigraphic sequence of the Cave of Kaf Taht el-Ghar (Dar Ben Karrich, Tétouan, Morocco) excavated in 2012 in the framework of the AGRIWESTMED research project. The broad sequence reveals a series of occupations ranging from the Pleistocene (Moroccan Aterian) to recent historical times. Our research identifies a rich Early Neolithic phase (sixth millennium cal BC) containing the earliest pottery and domesticated animal and plant remains in the western Maghreb. However, this Early Neolithic level is not an immediate successor of the last traces of the Epipalaeolithic hunter-gatherer occupation, which started at the end of the Younger Dryas (10,900–9700 …

Alu insertion polymorphisms in the African Sahel and the origin of Fulani pastoralists.

2017

The origin of Western African pastoralism, represented today by the Fulani nomads, has been a highly debated issue for the past decades, and has not yet been conclusively resolved.This study focused on Alu polymorphisms in sedentary and nomadic populations across the African Sahel to investigate patterns of diversity that can complement the existing results and contribute to resolving issues concerning the origin of West African pastoralism.A new dataset of 21 Alu biallelic markers covering a substantial part of the African Sahel has been analysed jointly with several published North African populations.Interestingly, with regard to Alu variation, the relationship of Fulani pastoralists to …

First report of the rare tooth fungus Hericium erinaceus in North African temperate forests

2018

The rare fungus Hericium erinaceus (Bull.) Pers. was collected from temperate forests in northwestern Tunisia and described for the first time in Africa. In this paper, we report data about the distribution, ecology, morphology and molecular identification of H. erinaceus. Collected data may help expand our knowledge on this critically endangered rare species worldwide.

Chemical characterization of organic residues on Late Roman amphorae from shipwrecks off the coast of Marsala (Trapani, Italy)

2021

Abstract Organic residues were extracted from thirty-three different types of Roman and Late Antique amphorae retrieved from underwater contexts in the custody of the Archaeological Museum “Baglio Anselmi” of Marsala in Sicily. The samples were analysed using GC-MS and 1H NMR, finding biomarkers of plant oils (including saturated and unsaturated fatty acids, alcohols and alkanes present in plant waxes) were identified in seven samples. The biomarkers for Pinaceae spp., used for making pitch, were identified in one sample. The results obtained shed light on the function of different types of North African amphorae, traditionally interpreted as containers for olive oil, wine and fish sauce, p…

XRF and LA-ICP-MS studies of gold and silver artefacts from a 12–13th century CE tumulus in Senegal: Implications for the medieval African gold trade

2019

Abstract Silver and gold artefacts from a 12–13th c. CE tumulus in Senegal were recently analysed by means of XRF and LA-ICP-MS. The identification of major, minor and trace elements allowed gaining a rare insight into the composition of precious metals circulating in that part of Africa in medieval times. The results show that all objects were made of polymetallic alloys. Comparisons with analyses from other West African as well as North African and European silver and gold artefacts suggest that the metal from the studied objects most probably originate from outside West Africa. At least in the case of the gold artefacts, this is quite surprising, as we expected to come across pure West A…

The relationship between communication apprehension and linguistic fluency: an analysis of North African and Russian immigrants in France

2013

North African and Russian immigrants in France were recruited (334) to complete a survey investigating the relationships between communication apprehension (CA) and linguistic fluency. Correlation analysis revealed a negative relationship between linguistic fluency in the dominant language and CA, meaning individuals who are fluent in the dominant language tend to be less apprehensive. Moreover, independent samples t-tests revealed Russian immigrants score higher on CA than do North African immigrants. Theoretical implications regarding the importance of studying Islam, linguistic fluency, and cultural adaptation are presented.

La participación en asociaciones de los inmigrantes africanos. Vías de interpretación del distanciamiento asociativo

2013

This article is focused on the reasons for non-participation of African population in immigrant associations. To understand this question, we conducted semi-structured interviews with persons who decided consciously no to participate in associations and organizations that worked with immigrants. All this work was developed in Catalonia, Valencia and Navarra, from a multilocal research perspective. We interpret the associative detachment, as a voluntary distancing based on the absence of information, lack of time, disenchantment, proprietorship activism, passively waiting, or because they are the only user population. Nevertheless, there are other factors of greater significance, as the poli…

Educational Inequalities of the Second GenerationIn France and in the United States: school careers and attainment

2009

09025; Document de travail. Rapport pour la Nuffield Foundation. 34 p.; This paper aims to compare the educational outcomes of the second generation in France and in the United States and therefore to shape the patterns of educational inequality in both countries. The comparison is focused on children from two groups: North Africans in France and Mexicans in the US (compared to French born families and White third generation). By using two longitudinal datasets, the National Educational Panel Survey (Panel 95) of the French Ministry of Education and the National Longitudinal Study of Adolescent Health (Add Health), we examine their educational aspiration, careers and attainment in secondary…
