La ruptura de una economía moral y las deslegitimación de las deudas hipotecarias

In Spain, during the recent housing bubble, purchasing a home seemed the most advantageous strategy to access housing, and there was a wide social consensus about the unavoidability of mortgage indebtedness. However, such consensus has been challenged by the financial and real-estate crisis. The victims of home repossessions have been affected by the transgression of several principles, such as the fair compensation for effort and sacrifice, the prioritisation of basic needs over financial commitments, the possibility of a second chance for over-indebted people, or the State's responsibility to guarantee its citizens' livelihood. Such principles may be understood as part of a moral economy, and their transgression has resulted in the emergence of a social movement, the Plataforma de Afectados por la Hipoteca (PAH), that is questioning the legitimacy of mortgage debts. The article reflects on the extent to which the perception of over-indebtedness and evictions as unfair situations can have an effect on the reproduction of the political-economic system, insofar the latter is perceived as able or unable to repair injustice.

Chondrogenic Differentiation Alters the Immunosuppressive Property of Bone Marrow-Derived Mesenchymal Stem Cells, and the Effect is Partially due to the Upregulated Expression of B7 Molecules

To investigate the immunosuppressive properties of mesenchymal stem cells (MSCs), in the present study we examined the immunogenicity of undifferentiated and tri-lineage (chondrocytes, osteoblasts and adipocytes) differentiated rat bone marrow-derived MSCs under xenogeneic conditions. After chondrogenic-differentiation, rat bone marrow-derived MSCs stimulated human peripheral blood monocyte-derived DCs (hDCs), leading to 8- and 4-fold higher lymphocyte proliferation and cytotoxicity than that of undifferentiated MSCs. The Chondrogenic-differentiated MSCs were chemotactic to hDCs in Dunn chamber chemotaxis system and were rosetted by hDCs inrosette assays. Flow cytometry analysis revealed that chondrogenic-differentiated MSCs had promoted hDCs maturation causing higher CD83 expression in hDCs, whereas undifferentiated MSCs, osteogenic-and adipogenic-differentiated MSCs showed inhibitory effect on hDCs maturation. The co-stimulatory molecules B7 were up-regulated only in the chondrogenic-differentiated MSCs. After blocking B7 molecules with specific monoclonal antibodies in the chondrogenic-differentiated MSCs, CD83 expression of co-cultured hDCs was greatly reduced. In conclusion, chondrogenic differentiation may increase the immunogenicity of MSCs, leading to stimulation of DCs. The up-regulated expression of B7 molecules on the chondrogenic differentiated MSCs may be partially responsible for this event.

Discourses on Modernization in the Employment Public Services: Towards a New Form of Governance?

The “crisis of the social issue” in the EU has led to a certain consensus in the need to renew the organizational and institutional model of public administration. The core of the reform implies important administrative changes in most of the European welfare states. Those changes are inspired on theories such as the new public management, management by objectives or partnership. Such changes involve both semantic (“sharing responsibilities”, “effective costs”, or the substitution of “citizen under an administration” by “consumer”) and political (predominance of scattered forms of power and the individualization of responsibilities) transformations which operate in the framework of individuals and State relations. The paradigms of activation and flexicurity have been central in this public administration modernization project. This commitment with new forms of governance of social issues has important consequences for the political and moral foundations of social cohesion, and the Spanish case is not an exception. This paper aims at looking at those representations of “modernization” (as they appear in debates about the employment services restructuring policies) in detail as well as providing references to the trajectory of such reforms of public services since the early eighties to the beginning of the crisis.

Prueba de inmigración y márgenes legales del desencuentro. Políticas públicas, prácticas sociales y construcción de la persona

La redacción de las directrices y los procedimientos administrativos que hacen virtualmente posible la inmigración, contribuye a construir no sólo los itinerarios sino también el imaginario social sobre la alteridad. El principal objetivo del artículo es poner de relieve –mediante el análisis discursivo de las Hojas informativas publicadas en la WEB del Ministerio de Empleo y Seguridad Social- cómo la construcción social del emigrante/inmigrante y el proyecto migratorio topan con unas representaciones y envites, instituidos y refrendados  en y por la propia formulación de la reglamentación, pero no del todo explícitos. Entendiendo el texto como una acción que genera otras acciones, se examinan las consecuencias que tiene sobre la practica social de los inmigrantes. En suma, se trata  de vislumbrar los elementos (terminología, fórmulas, esquemas y prácticas inducidas) que van constituyendo al inmigrante como agente social subordinado a micro-procesos y relaciones que se le escapan en gran parte (en contra de las apariencias que parecieran sugerir lo contrario) y van marcando su propia capacidad de acción. En conclusión y retomando la distinción entre principio de diferencia y principio de indiferencia sugerida por Foucault, se muestra que mientras el primero rige las clausulas generales, el segundo articula las específicas.

E-Commerce Innovations in the Personal Tax System of the United Kingdom

This study finds evidence that attempts to reduce costs and error rates in the Inland Revenue through the use of e-commerce technology are flawed. While it is technically possible to write software that will record tax data, and then transmit it to the Inland Revenue, there is little demand for this service. The key finding is that the tax system is so complex that many people are unable to complete their own tax returns. This complexity cannot be overcome by well-designed software. The recommendation is to encourage the use of agents to assist taxpayers or simplify the tax system. The Inland Revenue is interested in saving administrative costs and errors by encouraging electronic submission of tax returns. To achieve these objectives, given the raw data it would seem clear that the focus should be on facilitating the work of agents.

Characterization and Modeling of the Indoor Radio Channel at 868 MHz for a Mobile Bodyworn Wireless Personal Area Network

This letter reports the statistical characterization and modeling of the indoor radio channel for a mobile wireless personal area network operating at 868 MHz. Line of sight (LOS) and non-LOS conditions were considered for three environments: anechoic chamber, open office area and hallway. Overall, the Nakagami-m cdf best described fading for bodyworn operation in 60% of all measured channels in anechoic chamber and open office area environments. The Nakagami distribution was also found to provide a good description of Rician distributed channels which predominated in the hallway. Multipath played an important role in channel statistics with the mean recorded m value being reduced from 7.8 in the anechoic chamber to 1.3 in both the open office area and hallway.
