Genome-wide scan for selection signatures reveals novel insights into the adaptive capacity in local North African cattle
2020
International audience; Natural-driven selection is supposed to have left detectable signatures on the genome of North African cattle which are often characterized by the fixation of genetic variants associated with traits under selection pressure and/or an outstanding genetic differentiation with other populations at particular loci. Here, we investigate the population genetic structure and we provide a first outline of potential selection signatures in North African cattle using single nucleotide polymorphism genotyping data. After comparing our data to African, European and indicine cattle populations, we identified 36 genomic regions using three extended haplotype homozygosity statistic…

El acceso de los hijos de inmigrantes a la Educación Superior en España ¿una cuestión de origen étnico o de origen social?
2021
El presente trabajo se enmarca dentro de los estudios sobre la Dimensión Social de la Educación Superior (DOES). En él se estudia el peso que la posición socioeconómica tiene en el acceso a la Educación Superior de las segundas generaciones en España. Para ello analizamos la probabilidad de que los estudiantes con antecedentes migratorios y diferentes orígenes socioeconómicos realizaran estudios terciarios durante la segunda década del siglo XXI en contraste con la población autóctona de nuevo ingreso. En nuestros resultados encontramos diferencias significativas en el acceso a la universidad entre los jóvenes con edades comprendidas entre los 18 y 21 años, pertenecientes a las segundas gen…
Importation and Trade of African Pottery in the Ancient Ecclesia Carinensis During the Late Roman Age
2015
The territory of Carini, on the northwest coast of Sicily, 30 km from Palermo, is often mentioned by ancient sources. According Thucydides in this area was located the ancient Hykkara. Itinerarium Antonini recalls the statio of Hykkara along the via Valeria. This route in Late Antiquity became very important for the deportatio ad aquam of the agricoltural products. Gregorius Magnus in the epistles (VI century A.D.) mentions a diocese of Karines, as witnessed alike by the acts of synods to 782. The archaeological excavations, still ongoing, in the Early Christian cemetery nearby the little modern town of Villagrazia di Carini have revealed the presence of a strong Christian community. The se…
Moors and Saracens in Europe: estimating the medieval North African male legacy in southern Europe.
2009
To investigate the male genetic legacy of the Arab rule in southern Europe during medieval times, we focused on specific Northwest African haplogroups and identified evolutionary close STR-defined haplotypes in Iberia, Sicily and the Italian peninsula. Our results point to a higher recent Northwest African contribution in Iberia and Sicily in agreement with historical data, southern Italian regions known to have experienced long-term Arab presence also show an enrichment of Northwest African types. The forensic and genomic implications of these findings are discussed.
Migration Control in the Mediterranean Grenzsaum: Reading Ratzel in the Strait of Sicily
2014
Migration controls are more and more transforming borders. In this regard, this paper is a border case study focusing on the Strait of Sicily. It analyzes the border regime between Italy and its North African neighboring countries Tunisia and Libya from the point of view of the transformations of territorial borders in space and time. It provides an inventory of border control measures and instruments, and analyzes the way they actually work. The evolution of policies and practices of migration controls results in transformations of territorial borders not only in terms of their location (inward and outward flexibilization of the border) but also in terms of their shape (from boundary lines…
Profetismo político, milenarismo y creencias mesiánicas en el último periodo del reinado de Fernando el Católico (1500-1516)
2019
This study analyzes the presence of messianic and millennial beliefs in the last period of Ferdinand the Catholic?s reign. For this and after a brief state of the art, we analyze the use of the Christian prophecy of the millennium in speeches and memorials arising from the war in Naples, the North African campaign and the Pisan schism.
On the occurrence of the silverstripe blaasop Lagocephalus sceleratus (Gmelin, 1789) along the Libyan coast
2012
Five individuals of Lagocephalus sceleratus were caught by trammel and gill nets off Ain Al Ghazala, Libya (approximately 32°09'N − 23°15'E) between 15 and 25 m depth in September 2010. Our findings represent the first record of this toxic species from Libya and provide further evidence of its occurrence along North African coasts.
The access and success in the different higher education tracks in France for female and male youths of North African backgrounds
2016
International audience; Despite their preference for selective vocational programmes, many youths of North African backgrounds, including female youths, are diverted toward academic university programmes. To what extent do successful or unsuccessful applications to a chosen programme determine higher education outcomes and transition to work, particularly for female North African youths? Our results show that unemployment is higher for drop-outs for both North African men and women compared to their French counterparts.
Sphenoid sinus mucocele : an unusual complication of head and neck irradiation in a North African woman
2019
Mucocele is a common benign lesion otherwise rarely located in the sphenoid sinus. Some complications after head and neck irradiation have been described in the literature until now. To our knowledge, this is the first report of a sphenoid sinus mucocele in a North African patient treated some years before with radiotherapy for a nasopharyngeal carcinoma (NPC). We extend the literature review about this infrequent finding, of which head and neck surgeons should be aware. Key words:Mucocele, sphenoid sinus mucocele, nasopharyngeal carcinoma, radiotherapy, North African.
