UNC-52/perlecan affects gonadal leader cell migrations in C. elegans hermaphrodites through alterations in growth factor signaling.
2003
0012-1606 doi: DOI: 10.1016/S0012-1606(03)00014-9; The unc-52 gene of Claenorhabditis elegans encodes a homologue of the basement membrane heparan sulfate proteoglycan perlecan. Viable alleles reduce the abundance of UNC-52 in late larval stages and increase the frequency of distal tip cell (DTC) migration defects caused by mutations disrupting the UNC-6/netrin guidance system. These unc-52 alleles do not cause circumferential DTC migration defects in an otherwise wild-type genetic background. The effects of unc-52 mutations on DTC migrations are distinct from effects on myofilament organization and can be partially suppressed by mutations in several genes encoding growth factor-like molecu…
Impact of the COVID-19 Pandemic on the Legal Migrant in Poland, Portugal, Latvia, and Belgium
2021
Purpose: The article aims to analyze the impact of the COVID-19 pandemic about legal migrants in selected European Union countries amidst the tighter restrictions and travel constraints introduced worldwide. Design/Methodology/Approach: The article uses data and source analysis and a modeling method to demonstrate the extrapolation of migration trends. Findings: The employed methodology enabled the authors to establish that in Poland, Portugal, Latvia, and Belgium, measures were taken to respond to the COVID-19 pandemic in the context of legal migrants residing on their territories during the introduction of the movement restrictions. Practical Implications: According to the authors, the ex…
Les migrations des étudiants francs-comtois vers les universités limitrophes
2001
La mobilité géographique des étudiants est un phénomène d'intérêt régional. Pourquoi va t-on étudier dans telle université, pour la qualité ou l' originalité de ses formations, pour la richesse culturelle de la ville qui l'héberge?
Mobilités géographiques étudiantes : quelles disparités régionales
2005
Rapport; Depuis les lois de décentralisation, depuis le dernier plan de redéploiement « Université 2 000 », le niveau régional a acquis une nouvelle légitimité non seulement en tant que niveau d'observation des structurations de l'offre de formation supérieure et des marchés de l'emploi mais aussi et surtoutcomme territoire de revendications et d'actions.Or, les situations régionales liées aux populations jeunes, qu'il s'agisse des bacheliers, des étudiants inscrits à l'Université ou des diplômés accédant àun premier emploi, apparaissent extrêmement contrastées. Par la mobilisation de nombreuses sources d'informations, par leurs traitementssystématiques et cartographiques, l'approche simult…
Mobilités étudiantes et territoires universitaires : vers une uniformisation des pratiques ?
2005
Since French Society enters the so-called "Economy of knowledge", migrations of young people, especially these concerning students, are of most interest. Despite the fact that it could help to understand University as a system and ways regions can evolve, the study of students' migrations was not yet done. A set of results highlights first the main role of French capital region. It also shows main changes in migrations of students following vocational training in University. At least, it reveals that architectures of students' migrations look like these of migrations of the whole French population.

Contra l'alteritat. L'erosió de la dicotomia jo/altre a «La pell de la frontera» (2016), de Francesc Serés
2018
En aquest article em propòs reflexionar sobre la recerca de mecanismes de representació literària de la diferència cultural i econòmica que es proposen erosionar la separació que justifica la dicotomia jo/altre. Ho faré a partir de l'estudi d'un cas concret: el volum La pell de la frontera (2014) de Francesc Serés. Aquest llibre contribuí a difondre la situació desesperada de molts migrants, així com també a denunciar la desatenció institucional davant d'uns canvis socials, econòmics i demogràfics que han modificat d'arrel la composició de molts pobles del Baix Cinca i del Segrià. En la meva lectura partiré de la hipòtesi que la representació dels objectes emprats i dels escenaris ruïnosos …
Fare rotta verso nuove terre: la diaspora greco-albanese della prima età moderna
2021
The contribution aims to frame the diasporic phenomenon of the 15th-16th centuries of the Balkan populations from areas roughly corresponding today to Albania and Greece, reading it according to a plurality of levels and intertwining that characterize the Mediterranean modern age history. Specifically, the paper summarizes the most recent reflections on the subject and focuses on the reasons that triggered the migration flows and on the historiographical narration over the centuries.
The spread of steppe and Iranian-related ancestry in the islands of the western Mediterranean
2020
Steppe-pastoralist-related ancestry reached Central Europe by at least 2500 bc, whereas Iranian farmer-related ancestry was present in Aegean Europe by at least 1900 bc. However, the spread of these ancestries into the western Mediterranean, where they have contributed to many populations that live today, remains poorly understood. Here, we generated genome-wide ancient-DNA data from the Balearic Islands, Sicily and Sardinia, increasing the number of individuals with reported data from 5 to 66. The oldest individual from the Balearic Islands (~2400 bc) carried ancestry from steppe pastoralists that probably derived from west-to-east migration from Iberia, although two later Balearic individ…
