Floristic affinities between the somali and the mediterranean regions
1988
The phytogeographical connections between Somalia and the Mediterranean Region were analyzed. 99 families and about 300 genera turned out to be common to the two areas, representing 67 per cent of the families and 32 per cent of the genera in the whole Somali flora. If considering only the flora of the northern portion of Somalia, these values respectively reach 76 per cent of the families and 40 per cent of the genera. Furthermore several species are common to the two areas, some showing continuous distribution between eastern Africa and the Mediterranean Region, while others have strongly disjunct distribution.
Mobilités géographiques étudiantes et qualifications des territoires : quelques disparités régionales
2003
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 surtout comme territoire de revendications et d'actions.Or, les situations régionales liées aux popul; 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 surtout co…
DETERMINANTS OF EDUCATIONAL ADVANCEMENT OF RURAL AREAS IN POLAND
2017
The article is an aimed attempt at the diagnosis and evaluation of the educational level (character) of rural population in Poland perceived as educational advancement as well as of its environment (background). Growing importance of education in improving professional opportunities, changing educational aspirations and parents’ support as well as positive internal migration trends were emphasised. Rural regions are still lagging behind urban areas, though optimistic characteristics indicate receding stigmatisation and marginalisation of the Polish country with internal migration of young and educated individuals, including affluent ones (potential luxury goods buyers), to rural area…
Social representations of latin american immigrants about immigration, care and elderly caregivers
2013
Ageing in Spain has increased considerably and elderly people often find themselves in a situation of great dependence. Facing this situation, many have had the support of immigrant caregivers from Latin America. This research had the purpose to know the social representations (SR) of these caregivers, living in Valencia (Spain), about immigration, care and elderly care. It involved the participation of 35 immigrants who responded the Word Association Test and a socio-demographic questionnaire. The results revealed that the SR on immigration reflect "nostalgia", care was represented by "help", and care for the elderly by "respect". It is concluded that the SR allow understanding the symboli…
Meta-Analysis of Mitochondrial DNA Reveals Several Population Bottlenecks during Worldwide Migrations of Cattle
2014
Several studies have investigated the differentiation of mitochondrial DNA in Eurasian, African and American cattle as well as archaeological bovine material. A global survey of these studies shows that haplogroup distributions are more stable in time than in space. All major migrations of cattle have shifted the haplogroup distributions considerably with a reduction of the number of haplogroups and/or an expansion of haplotypes that are rare or absent in the ancestral populations. The most extreme case is the almost exclusive colonization of Africa by the T1 haplogroup, which is rare in Southwest Asian cattle. In contrast, ancient samples invariably show continuity with present-day cattle …
Gli Albanesi in Istria (secc. XV-XVIII)
2020
Albanian emigration was a historic phenomenon which extended over a long period, and of which different countries of the inter-Adriatic area were the final destination. Besides different regions in present-day Italy, Istria as well constituted a destination. The Albanians arrived there at the end of the 15th century. According to documents from archives, the Istrian settlement displays the connotations of similar migrations – though the latter were much more complex – across the Italian peninsula. Documents reflect the common organisational skills of various groups of migrants.
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…

Border Maps. (Counter-)cartographies of the Mediterranean
2020
Negli ultimi decenni il Mediterraneo è stato progressivamente tra- sformato in una frontiera liquida, uno spazio in cui le tecnologie di governo della mobilità si imprimono violentemente sui corpi di coloro i quali cercano di raggiungere l’Europa. Nonostante la rap- presentazione di flussi ed eventi migratori rappresenti una sfida per la cartografia e la sua geometria statica di confine, numerosi sono i tentativi recenti di utilizzo del linguaggio cartografico per rappre- sentare quel che accade alle frontiere meridionali d’Europa, specie nell’ambito della cartografia critica e radicale. Questo intervento si propone di esplorare la relazione fra eventi migratori e pratiche di (counter-)mapp…
