Missatges autoreferencials dels actors del ritual de l'Id-al-ad·ha

L'article analitza la celebració de l'Id-al-ad·ha o "festa del sacrifici", ritual protagonitzat per la comunitat de musulmans el desè dia del mes de dhu-al-hijja. Es parteix d'exemples etnogràfics procedents del context de la diàspora musulmana al Tarragonès i de la societat emiral mauritana. El fenomen s'analitza des dels rols que els actors exerceixen en el ritual. L'argumentació vol subratllar la idea que tot ritual s'inscriu en un context social específic del qual n'és producte alhora que modulador, per mitjà del que Roy Rappaport anomena "missatges autoreferencials". Això no exclou l'existència d'un conjunt de denominadors comuns o "missatges canònics" entre les diverses pràctiques rituals referides.

Family impact in intellectual disability, severe mental health disorders and mental health disorders in ID. A comparison

Family impact (or family burden) is a concept born in the field of mental health that has successfully been exported to the ambit of intellectual disability (ID). However, differences in family impact associated with severe mental health disorders (schizophrenia), to ID or to mental health problems in ID should be expected. Seventy-two adults with intellectual disability clients of the Carmen Pardo-Valcarce Foundation's sheltered workshops and vocational employment programmes in Madrid (Spain), 203 adults diagnosed with schizophrenia from four Spanish Community Mental Health Services (Barcelona, Madrid, Granada and Navarra) and 90 adults with mental health problems in ID (MH-ID) from the Parc Sanitari Sant Joan de Déu Health Care Site in Sant Boi de Llobregat, Barcelona (Spain) were asked to participate in the present study along with their main caregivers. Family impact experienced by caregivers was assessed with the ECFOS-II/SOFBI-II scale (Entrevista de Carga Familiar Objetiva y Subjetiva/Objective and Subjective Family Burden Interview). In global terms, results showed that the higher family impact was found between caregivers to people with MH-ID. The interaction of both conditions (ID and mental health problems) results in a higher degree of burden on families than when both conditions are presented separately. There was also an impact in caregivers to people with schizophrenia, this impact being higher than the one detected in caregivers to people with intellectual disability. Needs of caregivers to people with disability should be addressed specifically in order to effectively support families.

Id Gene regulation and function in the prosensory domains of the chicken inner ear: a link between Bmp Signaling and Atoh1

Bone morphogenetic proteins (Bmps) regulate the expression of the proneural gene Atoh1 and the generation of hair cells in the developing inner ear. The present work explored the role of Inhibitor of Differentiation genes (Id1-3) in this process. The results show that Id genes are expressed in the prosensory domains of the otic vesicle, along with Bmp4 and Bmp7. Those domains exhibit high levels of the phosphorylated form of Bmp-responding R-Smads (P-Smad1,5,8), and of Bmp-dependent Smad transcriptional activity as shown by the BRE-tk-EGFP reporter. Increased Bmp signaling induces the expression of Id1-3 along with the inhibition of Atoh1. Conversely, the Bmp antagonist Noggin or the Bmp-receptor inhibitor Dorsomorphin elicit opposite effects, indicating that Bmp signaling is necessary for Id expression and Atoh1 regulation in the otocyst. The forced expression of Id3 is sufficient to reduce Atoh1 expression and to prevent the expression of hair cell differentiation markers. Together, these results suggest that Ids are part of the machinery that mediates the regulation of hair cell differentiation exerted by Bmps. In agreement with that, during hair cell differentiation Bmp4 expression, P-Smad1,5,8 levels and Id expression are downregulated from hair cells. However, Ids are also downregulated from the supporting cells which contrarily to hair cells exhibit high levels of Bmp4 expression, P-Smad1,5,8, and BRE-tk-EGFP activity, suggesting that in these cells Ids escape from Bmp/Smad signaling. The differential regulation of Ids in time and space may underlie the multiple functions of Bmp signaling during sensory organ development.

Las condiciones de reproducción de la unidad familiar campesina en la Catalunya Nova: las "Terres de Lleida"

El trabajo intenta evaluar la dimensión mínima de la tierra que debiera poseer la unidad familiar campesina para garantizar su reproducción en el marco histórico de la etapa final de la Edad Moderna. Geográficamente, el trabajo se refiere a las tierras del interior llano catalán, que experimentaron durante el siglo XVIII un notable proceso de colonización agraria para atender los déficits cerealísticos del litoral catalán. Dado que la mayor parte del campesinado no disfruta de explotaciones viables económicamente, se analizan las estrategias campesinas encaminadas a la obtención de ingresos complementarios. Estas, lejos de situarse en actividades no agrarias, tienen una estrecha relación con la agricultura y con el aprovechamiento de los recursos naturales.

Author Rights vs Self-Archiving in Spanish Scientific Journals

The paper analyzes publishers" copyright policies and self-archiving conditions of Spanish scientific journals. Data are extracted from the directory DULCINEA that contains information of 1318 Spanish journals, of which 775 (61%) allow some form of self-archiving to be about 60% of the post-print version and allowing them 87% of the deposit of the version of record. In 72% of journals the deposit can be performed immediately after publication and in 16% after article acceptance. 72% of the journals are freely available without charge to the user this figure raises up to 86% if free access after an embargo is considered. Only 18% of the journals use Creative Commons licenses. The adoption of different open access journals model in Spain is favorable, however there is still a high percentage of journals (39%) that do not provide any information about authors and publishers rights and that difficult or inhibits reuse of published articles.
