Return Migration in the Ecuadorian and Bolivian population: motivations, strategies and discourses

This article analyses the motivations for return migration among the Ecuadorians and Bolivians who, after living in Spain, returned to their countries of origin during the economic crisis that started in 2008. From the analysis of 22 interviews in-depth which took place in Ecuador and 38 in Bolivia to women, men and young people from migrant families, this decision-making process is shown to be embedded into a gendered dynamics of relationships. Particular detail is given to affective and economic elements that had an influence on the decision to return, as well as to the strategies deployed to project their readjustment back in origin. Males and females occupy differential positions within the family, work and social circle, their expectations being built in a gendered manner. Despite the fact migration has brought women greater economic power within the family group, their reintegration upon return redefines their role as main managers in the household and the dynamics that allow their social reproduction. Men, for their part, aspire to refresh their role as providers in spite of their frail labour position upon return. Social mobility for females is passed on through generations by a strong investment on education for their daughters and sons, while for males this mobility revolves around setting up family businesses and around their demonstrative abilities.

La syndicalisation des travailleurs de l'amiante : le cas d'East-Broughton 1936-1943

Le 22 novembre 1942, un arrêt de travail se produit dans la section dite de l'empochage de la mine d'amiante Québec Asbestos d'East-Broughton. D��s lors il faut se demander si cet arrêt de travail est une grève ou un lock-out, car ce conflit se d��roule pendant une période de crise où le gouvernement interdisait toute grève ou lock-out. A travers ce conflit, on remarque que les mineurs se regroupent pour mettre leurs intérêts en commun. A première vue il est certain que la question primordiale était un rajustement des salaires. Par contre, on peut aussi remarquer que la question de la reconnaissance syndicale prend elle aussi une place importante à l'intérieur de cet arrêt de travail. Donc, mon projet de recherche concerne la syndicalisation dans l'industrie minière et plus particulièrement la syndicalisation des travailleurs de l'amiante: le cas d'East-Broughton 1936-1943. Dans ce travail, il sera question de la formation du Syndicat National Catholique de l'Amiante d'East-Broughton (S.N.C.A.E.B.) et des problèmes rencontrés par ce dernier pour sa reconnaissance par la compagnie Québec Asbestos Corporation. En particulier, j'analyserai les événements qui se sont produits lors du lock-out de ladite mine, fin 1942 et d��but 1943…

The D(D-3)-anyon chain: integrable boundary conditions and excitation spectra

Chains of interacting non-Abelian anyons with local interactions invariant under the action of the Drinfeld double of the dihedral group D-3 are constructed. Formulated as a spin chain the Hamiltonians are generated from commuting transfer matrices of an integrable vertex model for periodic and braided as well as open boundaries. A different anyonic model with the same local Hamiltonian is obtained within the fusion path formulation. This model is shown to be related to an integrable fusion interaction round the face model. Bulk and surface properties of the anyon chain are computed from the Bethe equations for the spin chain. The low-energy effective theories and operator content of the models (in both the spin chain and fusion path formulation) are identified from analytical and numerical studies of the finite-size spectra. For all boundary conditions considered the continuum theory is found to be a product of two conformal field theories. Depending on the coupling constants the factors can be a Z(4) parafermion or a M-(5,M-6) minimal model.

Automated Feedback for 'Fill in the Gap' Programming Exercises

Timely feedback is a vital component in the learning process. It is especially important for beginner students in Information Technology since many have not yet formed an effective internal model of a computer that they can use to construct viable knowledge. Research has shown that learning efficiency is increased if immediate feedback is provided for students. Automatic analysis of student programs has the potential to provide immediate feedback for students and to assist teaching staff in the marking process. This paper describes a “fill in the gap” programming analysis framework which tests students’ solutions and gives feedback on their correctness, detects logic errors and provides hints on how to fix these errors. Currently, the framework is being used with the Environment for Learning to Programming (ELP) system at Queensland University of Technology (QUT); however, the framework can be integrated into any existing online learning environment or programming Integrated Development Environment (IDE)
