La noció d'Espanya a la Catalunya medieval

A partir de la necessitat de conèixer les bases del propi present i d'assolir puntals on arrelar els discursos de futur, ara i adés les diferents col·lectivitats es remeten als orígens, "l'obsessió pels orígens" deia Marc Bloch. I aquests, en una Europa que parla de l'Edat Mitjana com la infantesa de la pròpia identitat, s'aboquen a una època medieval on conflueixen -en el que des de la llunyania de la nostra quotidianitat pot semblar una amalgama poc destriada- tant les realitats gresoladores dels actuals signes d'identitat culrurals, socials i lingüístics, com les projeccions que delerosament hi cerquen les justificacions del present i els condicionants del furur. Així doncs, convé apamar bé l'espai físic i conceptual per definir adientment la realitat existent en aquells moments que han alimentat les arrels d'identitats que, travessant diferents estímuls al llarg de la història, han menat fins als nostres dies.

De la guerra de l'Empordà (1128) a la mortaldat de 1131: gènesi, extensió i extinció d'una fam. Per a una història de les crisis alimentàries a la Catalunya medieval

In the history of food shortages and subsistence crises which affected the Catalan counties during the eleventh and twelfth centuries, the famine of 1129-1131 deserves special mention. Originating in the war of 1128 involving the Empordà and neighboring counties, this famine affected the city of Barcelona and other points of Catalonia (Winter, 1131) and created conditions for the spread of a deadly epidemic (July 1130 -January 1132).

La historia medieval en las escuelas: ¿una visión deformada?

A menudo se acusa a los libros de texto escolares de transmitir una imagen falsa, peyorativa, de la Edad Media. Aunque semejantes reproches puedan parecer nuevos, las protestas contra la hostilidad a la Edad Media, que rechazan el tópico del oscurantismo medieval, han estado a la orden del día durante los dos últimos siglos. Sin embargo, es muy difícil encontrar en los modernos libros de historia nada que justifique la acusación de haber exagerado las tinieblas medievales. En general, los historiadores modernos, tanto liberales como socialistas, han mantenido una opinión favorable de las instituciones y la cultura medievales, llegando incluso a encomiar la obra de la Iglesia como resguardo de la civilización, pero sin ocultar sus aspectos irracionales y reaccionarios. Las acusaciones que Jacques Heers y Jeffrey Burton Russell dirigen contra una presunta falsificación de la historia medieval apuntan explícitamente contra la influencia del darwinismo y el anticlericalismo, lo cual nos pone sobre la pista de sus verdaderas motivaciones ideológicas.

Ideal and reality: do countries adopt and follow recommended procedures in comprehensive multiyear planning guidelines for national immunization programmes?

BACKGROUND: Meticulous steps and procedures are proposed in planning guidelines for the development of comprehensive multiyear plans for national immunization programmes. However, we know very little about whether the real-life experience of those who adopt these guidelines involves following these procedures as expected. Are these steps and procedures followed in practice? We examined the adoption and usage of the guidelines in planning national immunization programmes and assessed whether the recommendations in these guidelines are applied as consistently as intended. METHODS: We gathered information from the national comprehensive multiyear plans developed by 77 low-income countries. For each of the 11 components, we examined how each country applied the four recommended steps of situation analysis, problem prioritization, selection of interventions, and selection of indicators. We then conducted an analysis to determine the patterns of alignment of the comprehensive multiyear plans with those four recommended planning steps. RESULTS: Within the first 3 years following publication of the guidelines, 66 (86%) countries used the tool to develop their comprehensive multiyear plans. The funding conditions attached to the use of these guidelines appeared to influence their rapid adoption and usage. Overall, only 33 (43%) countries fully applied all four recommended planning steps of the guidelines. CONCLUSIONS: Adoption and usage of the guidelines for the development of comprehensive multiyear plans for national immunization programmes were rapid. However, our findings show substantial variation between the proposed planning ideals set out in the guidelines and actual use in practice. A better understanding of factors that influence how recommendations in public health guidelines are applied in practice could contribute to improvements in guidelines design. It could also help adjust strategies used to introduce them into public health programmes, with the ultimate goal of a greater health impact.

Magias y brujerías literarias en la Castilla medieval

El objetivo del presente trabajo es trazar una panorámica sobre algunas de las plasmaciones literarias más relevantes de la magia y de la brujería en las letras castellanas medievales y sobre sus significaciones históricas. Con tal propósito se comentan textos de Don Juan Manuel, Juan Ruiz, Juan de Mena o Garci Rodríguez de Montalvo, entre otros autores de los siglos XIII al XV, y se apuntan algunas coordenadas culturales que reformulan la especificidad del contexto hispánico en su marco europeo.

Opening The Fortress : the work of public gaze on the Swiss asylum reality

The Fortress (La Forteresse) is a 2008 documentary film by Fernand Melgar that reports the Swiss asylum reality from a distant but committed point of view. The documentary describes the life of asylum seekers awaiting in a federal centre the decision to grant them-or not-refugee status. It subtly raises the issue of the role that "textual realities", grasped from the spectator's point of view, play in the production of public discourses. Most of all, it subtly poses the question of the (Swiss) spectator as an actor of the asylum policy, in the context of a semi-direct democracy. After evoking the notion of sensible experience for linking spectatorship to politics, we look at how the documentary invites its model spectator to accept the film's moral premises. Furthermore, focusing on the Swiss public sphere, we deliver an account of the reception by empirical spectators, notably by a group of leftist activists that tend to subvert Melgar's intentions. This two-fold analysis leads us to exhibit that, in a context of discursive struggles, The Fortress generates an original space of deliberation and experience, which appeals to the public to exercise their political agency on asylum policy without being constricted by an antagonist framework.

Tamaño óptimo de muestra para evaluar el patrón de crecimiento de frutos de naranjo 'Valencia late'

Los modelos de crecimiento de frutos describen la evolución de su tamaño a lo largo del período de desarrollo. Con fines de pronóstico, estos modelos permiten estimar en forma anticipada el tamaño que alcanzarán los frutos al momento de la cosecha. Para lograr estimaciones insesgadas del tamaño de frutos a cosecha es necesario un diseño adecuado de muestreo en la etapa de recolección de datos. El objetivo del presente trabajo fue determinar el tamaño óptimo de muestra, compuesta por árboles (n) y frutos (m), para establecer modelos de crecimiento de frutos de naranjo 'Valencia late', que permitan estimar la distribución de tamaño a la cosecha. Se trabajó con el diámetro ecuatorial de frutos previo a la cosecha, proveniente de dos huertos comerciales ubicados en la provincia de Corrientes, Argentina, durante tres temporadas. Mediante modelos mixtos se estimaron las componentes de varianzas entre árboles y frutos, y posteriormente a partir de dos tipos de metodologías se determinó el tamaño de muestra óptimo. La variabilidad entre frutos fue superior a la variabilidad entre árboles. Para la determinación del patrón de crecimiento de frutos de naranjo 'Valencia late' mediante un muestreo bietápico, se sugiere seleccionar 7 árboles y 30 frutos de cada árbol, para lograr estimaciones del diámetro ecuatorial de frutos con una precisión entre el 2 y 3%.

Lake-level and salinity reconstruction from diatom analyses in Quillagua Formation (Late Neogene, Central Andean Forearc, Northern Chile)

A sedimentary and micropaleontological study of the Quillagua Formation provides a detailed paleohydrological reconstruction of the lacustrine system which occupied the present-day hyperarid Quillagua-Llamara fore-arc Basin (Northern Chile) from lattermost Miocene to Early Pliocene times.

Drumming in immersive virtual reality: the body shapes the way we play

It has been shown that it is possible to generate perceptual illusions of ownership in immersive virtual reality (IVR) over a virtual body seen from first person perspective, in other words over a body that visually substitutes the person's real body. This can occur even when the virtual body is quite different in appearance from the person's real body. However, investigation of the psychological, behavioral and attitudinal consequences of such body transformations remains an interesting problem with much to be discovered. Thirty six Caucasian people participated in a between-groups experiment where they played a West-African Djembe hand drum while immersed in IVR and with a virtual body that substituted their own. The virtual hand drum was registered with a physical drum. They were alongside a virtual character that played a drum in a supporting, accompanying role. In a baseline condition participants were represented only by plainly shaded white hands, so that they were able merely to play. In the experimental condition they were represented either by a casually dressed dark-skinned virtual body (Casual Dark-Skinned - CD) or by a formal suited light-skinned body (Formal Light-Skinned - FL). Although participants of both groups experienced a strong body ownership illusion towards the virtual body, only those with the CD representation showed significant increases in their movement patterns for drumming compared to the baseline condition and compared with those embodied in the FL body. Moreover, the stronger the illusion of body ownership in the CD condition, the greater this behavioral change. A path analysis showed that the observed behavioral changes were a function of the strength of the illusion of body ownership towards the virtual body and its perceived appropriateness for the drumming task. These results demonstrate that full body ownership illusions can lead to substantial behavioral and possibly cognitive changes depending on the appearance of the virtual body. This could be important for many applications such as learning, education, training, psychotherapy and rehabilitation using IVR.

Extending body space in immersive virtual reality: a very long arm illusion

Recent studies have shown that a fake body part can be incorporated into human body representation through synchronous multisensory stimulation on the fake and corresponding real body part- the most famous example being the Rubber Hand Illusion. However, the extent to which gross asymmetries in the fake body can be assimilated remains unknown. Participants experienced, through a head-tracked stereo head-mounted display a virtual body coincident with their real body. There were 5 conditions in a between-groups experiment, with 10 participants per condition. In all conditions there was visuo-motor congruence between the real and virtual dominant arm. In an Incongruent condition (I), where the virtual arm length was equal to the real length, there was visuo-tactile incongruence. In four Congruent conditions there was visuo-tactile congruence, but the virtual arm lengths were either equal to (C1), double (C2), triple (C3) or quadruple (C4) the real ones. Questionnaire scores and defensive withdrawal movements in response to a threat showed that the overall level of ownership was high in both C1 and I, and there was no significant difference between these conditions. Additionally, participants experienced ownership over the virtual arm up to three times the length of the real one, and less strongly at four times the length. The illusion did decline, however, with the length of the virtual arm. In the C2-C4 conditions although a measure of proprioceptive drift positively correlated with virtual arm length, there was no correlation between the drift and ownership of the virtual arm, suggesting different underlying mechanisms between ownership and drift. Overall, these findings extend and enrich previous results that multisensory and sensorimotor information can reconstruct our perception of the body shape, size and symmetry even when this is not consistent with normal body proportions.
