International trade and migrant networks: Is It really about qualifications?
2014
Personal characteristics of migrants could help to strengthen the impact of migrant networks on bilateral trade. While most of the attention has been focused on immigrants' educational attainment, this paper focuses on the relevance of the tasks carried out by migrants. Our empirical results confirm that the existence of a large number of foreign-born workers with managerial duties is critical to explain the reduction of transaction costs caused by migrant networks.
Environmentally driven changes in Baltic salmon oxidative status during marine migration.
2020
The fitness and recruitment of fish stocks can be markedly affected by environmental disturbances including global warming, eutrophication and contamination. Understanding the effects of environmental stressors on salmon physiology during marine residence is of a global concern as marine survival has decreased. We present a unique combination of physiological responses - antioxidant defence and oxidative damage biomarkers, stable isotopes and contaminant exposure biomarkers - measured from adult Atlantic salmon (Salmo salar) collected at the Baltic Sea and studied in relation to environmental variables and fitness estimates. The results demonstrate that feeding populations of salmon display…
Infancia migrante y educación trasnacional en la frontera de México-Estados Unidos
2013
[EN] Child and youth migration, along with that of the general population, is not an isolated matter of modern-day. In this article we wish to reference the matter of child and youth migration and the educational consequences derived from this. In the matter that concerns us we intend to convey a vision of the current reality of the cross-country migration in the Mexico-United States border. Examining the variables we have observed, according to the profile of children and youths that migrate back and forth from one neighboring country to another along with the process of inclusion into or exclusion out of the educational system both in Mexico as well as in their neighboring country, as wel…
A vascular perspective on neuronal migration
2015
During CNS development and adult neurogenesis, immature neurons travel from the germinal zones towards their final destination using cellular substrates for their migration. Classically, radial glia and neuronal axons have been shown to act as physical scaffolds to support neuroblast locomotion in processes known as gliophilic and neurophilic migration, respectively (Hatten, 1999; Marin and Rubenstein, 2003; Rakic, 2003). In adulthood, long distance neuronal migration occurs in a glial-independent manner since radial glia cells differentiate into astrocytes after birth. A series of studies highlight a novel mode of neuronal migration that uses blood vessels as scaffolds, the so-called vasop…
Becoming Politically Active: Life Courses and the Formation of Capitals among Young People of Migrant Origin in Finland
2020
This article focuses on the life courses of young people of migrant origin who are active in civic and political fields in Finland. The aim is to analyse, from the micro-level life course perspective, the issues in their lives that have helped them to become active. The article draws on empirical data collected using participatory methods. Four young people of migrant origin participated in the research process and contributed to the data analysis. The theoretical framework consists of Bourdieusian concepts of political habitus and emotional, cultural and social capital. The article shows that participants gained strong emotional capital during their childhood, which laid the groundwork for…
Well-Being without Employment? Promoting the Employability of Refugees
2020
There are more than 25 million refugees in the world. Many of them try to reach the Mediterranean in order to enter Europe. Spain is one of the countries that receive refugees and have to integrate them. Many refugees have experienced persecution in their countries, as well as forced migration, rape, diseases, etc. Their integration requires support and coordination from the government, health services, and social agents. The first step in achieving this integration is getting a job, which is currently an important issue. Thus, we aim to analyze the employability of a specific group of refugees in Spain and then develop and implement an intervention program to improve their employability. O…
E-selectin modulates the malignant properties of T84 colon carcinoma cells.
2002
The extravasation of metastatic cells is regulated by molecular events involving the initial adhesion of tumor cells to the endothelium and subsequently the migration of cells in the host connective tissue. E-selectin on endothelial cells and sialyl Lewis X carbohydrate component on tumor cells are mainly involved in the adhesion of colon carcinoma cells to the endothelium of target organ. Interaction of T84 colon cancer cells to purified E-selectin in vitro caused an increase in the tyrosine phosphorylation of a number of proteins as well as the modulation of cellular properties correlated to the metastatic phenotype. Specifically, E-selectin-stimulated actin reorganization, increased coll…
The German Expellee Organizations: Unity, Division, and Function
2016
In the early twenty-first century, the German expellee organizations (Vertriebenenverbände) are typically portrayed as a united entity, at least in the wider public realm. The dominance of the umbrella group Bund der Vertriebenen (BdV) tends to foster the perception that the German expellee lobby is a homogeneous and cohesive bloc, focused on promoting shared political goals. This has been evident, for instance, in the media coverage of the prolonged controversy about the proposed establishment of a Center Against Expulsions in Berlin, in which the BdV’s statements have generally been taken to represent the expellee movement as a whole.1 But how correct is that interpretation, particularly …
No Entrepreneurship without Opportunity: The Intersection of Return Migration Research and Entrepreneurship Literature
2019
Abstract The article proposes a theoretical discussion at the crossroads of the return migration scholarship with the entrepreneurship research. Its main goal is to build an analytical framework in which entrepreneurial experiences of international return migrants are conceptualized. The fertile theoretical legacy within the study of entrepreneurship along with an idealized view of the positive effects of migration constitute essential premises for understanding the biased outputs of the empirical studies of entrepreneurship upon return to the origin country. Firstly, the article draws on the main lines of theorising opportunities within the Weberian and Schumpeterian theoretical traditions…
Separated Children’s Migration in the Mediterranean Sea. An Ethnohistorical Perspective
2016
In the imaginary of Italian people, the Island of Lampedusa (Italy) has always been considered a paradise destination for summer holidays. The beauty of this small island at the heart of the Mediterranean Sea, far from big harbors and cities, with its rich biodiversity and unspoilt nature, has made it a national and international tourist attraction. However, in recent years its name become associated with scenes of tragic, desperate journeys made by people of different origins trying to reach Europe from North African coasts. This shift exists not only in Italian people’s perception, but also all over the world, as the news related to Lampedusa and other Italian areas affected by this pheno…
