Enfermeiras Portuguesas na Alemanha. Análise de factores de influência nos processos de emigração e de integração

Devido às alterações demográficas na UE, o recrutamento de profissionais de saúde torna-se para muitos países uma estratégia para enfrentar situações emergentes de escassez neste sector. A experiência da falta de enfermeiros no serviço de saúde alemão e o crescente desemprego de jovens enfermeiros em Portugal deu início ao recrutamento por parte da Alemanha de enfermeiros portugueses. Esta investigação qualitativa pretendeu examinar os motivos individuais das enfermeiras que levaram a esta emigração e mostrar os processos de integração, ao nível social e profissional na Alemanha. O fio condutor da análise deste processo migratório, é o foco no papel das redes sociais e no recrutamento pelos empregadores alemães. Através da análise qualitativa de conteúdo das entrevistas realizadas com as enfermeiras portuguesas na Alemanha, confirmou-se que, ao lado de considerações económicas e profissionais, é especialmente o momento no ciclo de vida e o apoio da família no país de origem, os responsáveis pelo surgimento desta emigração. Em relação à escolha do país de destino, foram as relações sociais dos migrantes, nomeadamente a emigração dentro de um grupo de enfermeiros e a confiança transmitida pelo recrutamento directo dos empregadores que influenciaram fortemente a decisão. O contacto social no país de destino é determinado pela inserção em redes sociais com colegas compatriotas, disponibilizando capital social em forma de apoio emocional, mas ao mesmo tempo dificultando com a concentração na língua materna a criação de ligações fortes com a sociedade alemã. Face à integração profissional observaram-se certas práticas institucionais de recrutamento nomeadamente o investimento na aquisição da língua, como fundamentas pela satisfação profissional dos migrantes no país de destino.

Return Migration, Self-Selection and Entrepreneurship in Mozambique

Does return migration affect entrepreneurship? This question has important implications for the debate on the economic development effects of migration for origin countries. The existing literature has, however, not addressed how the estimation of the impact of return migration on entrepreneurship is affected by double unobservable migrant self-selection, both at the initial outward migration and at the final inward return migration stages. This paper uses a representative household survey conducted in Mozambique in order to address this research question. We exploit variation provided by displacement caused by civil war in Mozambique, as well as social unrest and other shocks in migrant destination countries. The results lend support to negative unobservable self-selection at both and each of the initial and return stages of migration, which results in an under-estimation of the effects of return migration on entrepreneurial outcomes when using a ‘naïve’ estimator not controlling for self-selection. Indeed, ‘naïve’ estimates point to a 13 pp increase in the probability of owning a business when there is a return migrant in the household relative to non-migrants only, whereas excluding the double effect of unobservable self-selection, this effect becomes significantly larger - between 24 pp and 29 pp, depending on the method of estimation and source of variation used.

Productivity gains from migration: An analysis of Cape Verdean return migrants

Are return migrants more productive than non-migrants? If so, is it a causal effect or simply self-selection? Existing literature has not reached a consensus on the role of return migration for origin countries. To answer these research questions, an empirical analysis was performed based on household data collected in Cape Verde. One of the most common identification problems in the migration literature is the presence of migrant self-selection. In order to disentangle potential selection bias, we use instrumental variable estimation using variation provided by unemployment rates in migrant destination countries, which is compared with OLS and Nearest Neighbor Matching (NNM) methods. The results using the instrumental variable approach provide evidence of labour income gains due to return migration, while OLS underestimates the coefficient of interest. This bias points towards negative self-selection of return migrants on unobserved characteristics, although the different estimates cannot be distinguished statistically. Interestingly, migration duration and occupational changes after migration do not seem to influence post-migration income. There is weak evidence that return migrants from the United States have higher income gains caused by migration than the ones who returned from Portugal.

Microfluidics: a new look at cell migration analysis

This thesis explores the development and employment of microfluidic devices as a tool for studying the effect of the surrounding environment on embryonic stem cells during the migration phenomena. Different single-cell microchips were designed and manufactured to study mouse embryonic fibroblasts (MEFs) migration towards an environmental variation (increase of serum concentration in the culture medium) that was expected to function as a motility stimuli. Considering the experimental, cells were injected into the microchips chambers and individually isolated by dedicated cell traps with view to a single-cell analysis. Once fribroblasts were attached to the surface, culture medium with an increased serum level was subsequently injected in an adjacent chamber to promote the formation of a serum concentration gradient. The gradient established between the chambers could be sensed by the fibroblasts and thus triggered the cells mobilization towards and in the direction of the richer serum medium. Additionally, the experiment allowed the observation of MEFs’ structural reorganization when migrating through micro-tunnels containing widths below the cell size, suggesting a cytoskeleton rearrangement on account of the nutritional stimulus introduced. Furthermore, results indicate that fibronectin promotes MEFs adhesion to the substrate and that MEFs migration is characterized as haptotactic.

A wave of change: Labor market and social security impacts of the EU refugee inflow

The recent massive inflow of refugees to the European Union (EU) raises a number of unanswered questions on the economic impact of this phenomenon. To examine these questions, we constructed an overlapping-generations model that describes the evolution of the skill premium and of the welfare benefit level in relevant European countries, in the aftermath of an inflow of asylum-seekers. In our simulation, relative wages of skilled workers increase between 8% and 11% in the period of the inflow; their subsequent time path is dependent on the initial skill premium. The entry of migrants creates a fiscal surplus of about 8%, which can finance higher welfare benefits in the subsequent periods. These effects are weaker in a scenario where refugees do not fully integrate into the labor market.
