Salvadoran Migrants in Australia: An Analysis of Transnational Families’ Capability to Care across Borders

In this paper, I focus on the transnational care practices of Salvadoran refugees living in Perth (Western Australia) and who care for their ageing parents who have remained in their home country. The analysis is based on a conceptualization of transnational care as a set of capabilities that include, but are not limited to, mobility, social relations, time allocation, education and knowledge, paid work and communication (Merla and Baldassar, 2011). I focus in particular on the impact of Salvadoran refugees’ difficult access to, and use of, these capabilities on their capacity to fulfil their culturally defined sense of obligation to care for their ageing parents. Results show that extended transnational kinship networks play a major role in helping migrants overcome obstacles to transnational caregiving.     

Classification of biomedical signals for differential diagnosis of Raynaud's phenomenon

This paper discusses a supervised classification approach for the differential diagnosis of Raynaud's phenomenon (RP). The classification of data from healthy subjects and from patients suffering for primary and secondary RP is obtained by means of a set of classifiers derived within the framework of linear discriminant analysis. A set of functional variables and shape measures extracted from rewarming/reperfusion curves are proposed as discriminant features. Since the prediction of group membership is based on a large number of these features, the high dimension/small sample size problem is considered to overcome the singularity problem of the within-group covariance matrix. Results on a data set of 72 subjects demonstrate that a satisfactory classification of the subjects can be achieved through the proposed methodology.
