Heat fluxes and surface radiation measurements from Samoylov Island, Lena Delta, Siberia, October 2007 to March 2008

In this study, we present the winter time surface energy balance at a polygonal tundra site in northern Siberia based on independent measurements of the net radiation, the sensible heat flux and the ground heat flux from two winter seasons. The latent heat flux is inferred from measurements of the atmospheric turbulence characteristics and a model approach. The long-wave radiation is found to be the dominant factor in the surface energy balance. The radiative losses are balanced to about 60 % by the ground heat flux and almost 40 % by the sensible heat fluxes, whereas the contribution of the latent heat flux is small. The main controlling factors of the surface energy budget are the snow cover, the cloudiness and the soil temperature gradient. Large spatial differences in the surface energy balance are observed between tundra soils and a small pond. The ground heat flux released at a freezing pond is by a factor of two higher compared to the freezing soil, whereas large differences in net radiation between the pond and soil are only observed at the end of the winter period. Differences in the surface energy balance between the two winter seasons are found to be related to differences in snow depth and cloud cover which strongly affect the temperature evolution and the freeze-up at the investigated pond.

Perspectives on gender, migration and transnational work: joint work of social reproduction and care in Southern Europe

This paper presents the "state of the art" and some of the main issues discussed in relation to the topic of transnational migration and reproductive work in southern Europe. We start doing a genealogy of the complex theoretical development leading to the consolidation of the research program, linking consideration of gender with transnational migration and transformation of work and ways of survival, thus making the production aspects as reproductive, in a context of globalization. The analysis of the process of multiscale reconfiguration of social reproduction and care, with particular attention to its present global dimension is presented, pointing to the turning point of this line of research that would have taken place with the beginning of this century, with the rise notions such as "global care chains" (Hochschild, 2001), or "care drain" (Ehrenreich and Hochschild, 2013). Also, the role of this new agency, now composed in many cases women who migrate to other countries or continents, precisely to address these reproductive activities, is recognized. Finally, reference is made to some of the new conceptual and theoretical developments in this area.

The trace in the skin in an Art Therapy Workshop

We present the experience of a brief Art Therapy Workshop conducted with a group of women with dermatological conditions, conducted at the Hospital General Universitario Reina Sofía of Murcia. We will focus on one of the patients, recognizing the importance of group relationships for therapy. The main objective was to establish a link between emotions and experiences of patients and their own body, specifically their skin condition. Thus, personal, family and social will constitute the basis on which these emotions and experiences are embedded. The relationships and their status as mothers are guides for the therapeutic work carried out.

Ficción y documentación en "Hombre sin nombre" (2006), de Suso de ToroFicción y documentación en Hombre sin nombre (2006), de Suso de Toro

Hombre sin nombre pertenece a la modalidad de novela histórica que ambienta su relato en la Guerra Civil española, integrada en el proceso de recuperación de la “Memoria Histórica” impulsado precisamente en 2006; el trabajo se basa en la consulta y manejo de la rica documentación (bibliográfica, hemerográfica, testimonial, policial, judicial...) utilizada por el autor para construir su ficción narrativa.

El color en los códices prehispánicos del México Central: identificación material, cualidad plástica y valor estético

Este artículo investiga algunos de los valores plásticos y estéticos que presidieron la selección y la preparación de las materias colorantes empleadas para iluminar los códices creados por los nahuas del México Central durante el Posclásico Tardío. Estos códices son interesantes porque análisis arqueométricos y exámenes codicológicos recientes han permitido conocer la materialidad de su capa pictórica, así como las características formales y el comportamiento de los colores en estas obras. Uno de los aportes trascendentales de estos estudios ha sido averiguar que la paleta cromática que sirvió para pintar los códices del México Central era principalmente de origen orgánico, lo que contrasta con la naturaleza de los pigmentos detectados en restos de pintura mural y en esculturas creadas por los nahuas que son sobre todo minerales. El objetivo de este artículo es reflexionar sobre las razones de esas diferencias y demostrar que el uso de los colorantes orgánicos en los códices respondía a un fin plástico específico que concordaba con el canon estético imperante en la sociedad náhuatl.

El proceso de la elaboración de los códices "Borgia" y "Vaticano B" basado en su estudio codicológico

El objetivo de este artículo es presentar las observaciones realizadas durante la consulta de los originales de los códices Borgia (Borg. Mess. 1) y Vaticano B (Vat. Lat. 3773) en la Biblioteca Apostólica Vaticana en 2014. Este estudio codicológico, aunque a la fuerza parcial, dado que fue realizado solamente por medio de una observación directa, revela nuevos datos acerca de la elaboración de los manuscritos prehispánicos, tanto en la preparación de la piel como soporte como en los procedimientos aplicados a la hora de trazar las imágenes y corregir las equivocaciones.
