Getting Old Here and There: Opportunities and Pitfalls of Transnational Care Arrangements

This article focuses on challenges of transnational aging and family care among „guest-workers‟ from Italy and Spain. It is based on two qualitative studies on aging in migration and experiences of family care. These migrants‟ situations tend to be socioeconomically underprivileged, yet they have the option to either stay in Switzerland or return to Italy or Spain. Our results show that an additional option is available by combining elements of both national systems of reference. However, these options are often costly and have short-comings which are particularly relevant when ill health conditions demand intensified care. By then, decisions taken within the context of transnational ways of living have far-reaching consequences that affect not only the elderly migrants but also their adult children. The empirical data presented in this article illustrate how specific constellations of caring options emerge from the Swiss „guest-worker‟ migration regime and from transnational practices and choices made in earlier years.

Los franceses en el virreinato del Río de la Plata

El objetivo del presente artículo es estudiar a los franceses en el Virreinato del Río de la Plata desde la óptica de las autoridades coloniales. Se analiza la documentación del gobierno superior, del Cabildo y de la justicia para deducir quiénes eran y cómo fueron vistos y tratados los franceses por los vecinos y por las instituciones coloniales. Hasta al comienzo de la Revolución Francesa la imagen de aquellos era sobre todo, positiva y casi no se conservan en el archivo colonial registros sobre conflictos causados por este grupo en el virreinato. Con la Revolución, no obstante, los franceses se convirtieron en sospechosos y fueron objetivo de medidas de vigilancia, castigo y expulsión.

Citoyenneté, mondialisation et migration internationale : les réfugiés et demandeurs d’asile mexicains à Montréal

Cette recherche s’intéresse à la migration des Mexicains au Canada sous la forme de l’asile, flux migratoire que le Canada a tenté de contrer en resserrant ses frontières. Cette exclusion s’est produite simultanément à celle vécue par les Mexicains vivant ou désirant se rendre aux États-Unis. Ainsi, en Amérique du Nord, dans un contexte de profonde intégration économique, la majorité des Mexicains sont privés d’accès à la mobilité et par conséquent de la possibilité de jouir de droits à travers les frontières. Ce phénomène engendre un régime hiérarchisé de citoyenneté au sein de cet espace. Intimement reliée aux thèmes de l’inclusion / exclusion, la citoyenneté est surtout conceptualisée comme un statut rattaché à l’État ou comme un ensemble de droits dérivant de ce statut. Cette recherche met l’emphase sur de nouvelles manières d’appréhender ce concept, telles la citoyenneté comme un processus hégémonique ou comme une pratique. Ainsi, nous tentons de connaître les raisons pour lesquelles les Mexicains ont demandé l’asile à Montréal (Canada) et de quelles façons ces motifs peuvent être reliés à la citoyenneté. Nous cherchons à vérifier si l’exclusion des Mexicains aux États-Unis a un rôle à jouer dans cette migration. Nous explorons aussi la correspondance entre ce flux migratoire et le concept d’acte de citoyenneté, théorisé par Isin (2008), qui fait référence à une pratique où les individus revendiquent des droits, même s’ils ne possèdent pas le statut de citoyen. Les conclusions de cette recherche nous apprennent que les Mexicains ont demandé l’asile en raison d’une privation de citoyenneté substantielle au Mexique, fortement reliée à la formation de l’espace nord-américain. Par ailleurs, les demandes d’asile sont des conséquences directes de l’exclusion des Mexicains de cet espace. Qui plus est, elles coïncident avec la notion d’« acte de citoyenneté ». Finalement, le résultat de cet acte, qui cherchait l’inclusion et l’acquisition de droits, s’avère mitigé et inégal.

Migration to an a on-line laboatory in mechanical engineering. The case of a cam-follower design practice.

The European Higher Education Area (EHEA) has leaded to a change in the way the subjects are taught. One of the more important aspects of the EHEA is to support the autonomous study of the students. Taking into account this new approach, the virtual laboratory of the subject Mechanisms of the Aeronautical studies at the Technical University of Madrid is being migrated to an on-line scheme. This virtual laboratory consist on two practices: the design of cam-follower mechanisms and the design of trains of gears. Both practices are software applications that, in the current situation, need to be installed on each computer and the students carry out the practice at the computer classroom of the school under the supervision of a teacher. During this year the design of cam-follower mechanisms practice has been moved to a web application using Java and the Google Development Toolkit. In this practice the students has to design and study the running of a cam to perform a specific displacement diagram with a selected follower taking into account that the mechanism must be able to work properly at high speed regime. The practice has maintained its objectives in the new platform but to take advantage of the new methodology and try to avoid the inconveniences that the previous version had shown. Once the new practice has been ready, a pilot study has been carried out to compare both approaches: on-line and in-lab. This paper shows the adaptation of the cam and follower practice to an on-line methodology. Both practices are described and the changes that has been done to the initial one are shown. They are compared and the weak and strong points of each one are analyzed. Finally we explain the pilot study carried out, the students impression and the results obtained.

Understandings of transnational families in debates on Migration and development

International migration sets in motion a range of significant transnational processes that connect countries and people. How migration interacts with development and how policies might promote and enhance such interactions have, since the turn of the millennium, gained attention on the international agenda. The recognition that transnational practices connect migrants and their families across sending and receiving societies forms part of this debate. The ways in which policy debate employs and understands transnational family ties nevertheless remain underexplored. This article sets out to discern the understandings of the family in two (often intermingled) debates concerned with transnational interactions: The largely state and policydriven discourse on the potential benefits of migration on economic development, and the largely academic transnational family literature focusing on issues of care and the micro-politics of gender and generation. Emphasizing the relation between diverse migration-development dynamics and specific family positions, we ask whether an analytical point of departure in respective transnational motherhood, fatherhood or childhood is linked to emphasizing certain outcomes. We conclude by sketching important strands of inclusions and exclusions of family matters in policy discourse and suggest ways to better integrate a transnational family perspective in global migration-development policy.

Cross-shore transport in a daily varying upwelling regime: A case study of barnacle larvae on the southwestern Iberian coast.

With favored offshore and downstream advection, the question of which physical mechanism may promote onshore transport of larvae in upwelling systems is of central interest. We have conducted a semi-realistic high resolution (0.25 km) numerical study of Lagrangian transports across the inner-shelf under upwelling-favorable wind forcing conditions, focusing on the shelf area of the Southwestern Portuguese coast, in the lee of Cape Sines. We add our findings to several years of biological observations of C. montagui, a planktonic species with higher recruitment during the upwelling peak timely with the daylight flood. Simulations cover a fifteen days period during the summer of 2006. We focused on Spring and Neap tide periods and observed upfront differences between simulations and the in situ observa- tions. However, the model is capable of representing the main dynamics of the region, namely the re- petitive character of the inner-shelf currents. We find that the cross-shore flow varies significantly in the daily cycle, and locally within a scale of a few kilometers in association with local topography and the presence of the cape. We consider the region immediately in the lee of the cape to be an upwelling shadow where the larvae became retained, and found that tidally tied migration proves beneficial for successful recruitment during the spring tides period. Our work suggested that the wind is not the only mechanism responsible for the daily variability of the cross-shore exchange. However, its sharp reversal at midday is critical for the advection of larvae towards the coast.

Ankhd1 Silencing Inhibits Stathmin 1 Activity, Cell Proliferation And Migration Of Leukemia Cells.

ANKHD1 is highly expressed in human acute leukemia cells and potentially regulates multiple cellular functions through its ankyrin-repeat domains. In order to identify interaction partners of the ANKHD1 protein and its role in leukemia cells, we performed a yeast two-hybrid system screen and identified SIVA, a cellular protein known to be involved in proapoptotic signaling pathways. The interaction between ANKHD1 and SIVA was confirmed by co-imunoprecipitation assays. Using human leukemia cell models and lentivirus-mediated shRNA approaches, we showed that ANKHD1 and SIVA proteins have opposing effects. While it is known that SIVA silencing promotes Stathmin 1 activation, increased cell migration and xenograft tumor growth, we showed that ANKHD1 silencing leads to Stathmin 1 inactivation, reduced cell migration and xenograft tumor growth, likely through the inhibition of SIVA/Stathmin 1 association. In addition, we observed that ANKHD1 knockdown decreases cell proliferation, without modulating apoptosis of leukemia cells, while SIVA has a proapoptotic function in U937 cells, but does not modulate proliferation in vitro. Results indicate that ANKHD1 binds to SIVA and has an important role in inducing leukemia cell proliferation and migration via the Stathmin 1 pathway. ANKHD1 may be an oncogene and participate in the leukemia cell phenotype.

Variabilidade do regime de monções sobre o Brasil: o clima presente e projeções para um cenário com 2xCO2 usando o modelo MIROC

Este trabalho investiga a variabilidade do Sistema de Monções da América do Sul (SMAS) sobre o Brasil com particular interesse na região do cerrado brasileiro. O início, final e total de precipitação durante as monções de verão são examinados utilizando estimativas de precipitação por satélite (pêntadas) do Global Precipitation Climatology Project (GPCP) entre 1979-2004. Analogamente, as características do regime de monção simuladas pelo modelo climático global acoplado MIROC (Model for interdisciplinary Research on Climate) do IPCC (Intergovernmental Panel for Climate Change) são examinadas em dois cenários distintos: o clima do século XX (1981-2000) e o clima em uma condição com o dobro da concentração atual de CO2 (2xCO2) na atmosfera (2061-2080). Mostra-se que a variabilidade espacial do início da monção de verão sobre o cerrado na simulação do clima do século XX pelo MIROC corresponde bem às observações. Além disso, há indicação de uma mudança das caudas da distribuição sazonal da precipitação no Cerrado para um cenário com 2xCO2, comparativamente com o clima presente. Este resultado sugere uma mudança na probabilidade de ocorrência de eventos extremos (secos ou úmidos) em um cenário com 2xCO2 sobre o cerrado, o que de acordo com o MIROC, indica uma maior exposição da região às conseqüências de possíveis mudanças climáticas resultantes do aumento de gases de efeito estufa.

Brasil e brasileiros: notas sobre modelagem de significados políticos na crise do Antigo Regime português na América

Partindo da análise do significado político de Brasil e de brasileiro em documentos escritos por colonos em meados dos setecentos, o artigo aponta para a importância analítica do caráter desviante de variantes americanas da matriz societária portuguesa de tipo Ancien Régime. Trabalhando com os conceitos de memória e experiência, sustenta-se nele a idéia de que, por se tornarem assimétricas, as estruturas nacionais portuguesas dos dois hemisférios também se tornaram irredutíveis a um mesmo enquadramento constitucional quando da instauração da conjuntura revolucionária do final dos anos vinte do século XIX.

Paracoccidioides brasilinsis-Induced Migration of Dendritic Cells and Subsequent T-Cell Activation in the Lung-Draining Lymph Nodes

Paracoccidioidomycosis is a mycotic disease caused by a dimorphic fungus, Paracoccidioides brasiliensis (Pb), that starts with inhalation of the fungus; thus, lung cells such as DC are part of the first line of defense against this microorganism. Migration of DC to the lymph nodes is the first step in initiating T cell responses. The mechanisms involved in resistance to Pb infection are poorly understood, but it is likely that DC play a pivotal role in the induction of effector T cells that control Pb infection. In this study, we showed that after Pb Infection, an important modification of lung DC receptor expression occurred. We observed an increased expression of CCR7 and CD103 on lung DC after infection, as well as MHC-II. After Pb infection, bone marrow-derived DC as well lung DC, migrate to lymph nodes. Migration of lung DC could represent an important mechanism of pathogenesis during PCM infection. In resume our data showed that Pb induced DC migration. Furthermore, we demonstrated that bone marrow-derived DC stimulated by Pb migrate to the lymph nodes and activate a T helper (Th) response. To the best of our knowledge, this is the first reported data showing that Pb induces migration of DC and activate a T helper (Th) response.
