Producción y Productividad Agrícolas en la Isla de Mallorca, 1590-1860

This paper proposes a detailed measurement of the agricultural development of the island of Majorca from the late sixteenth century to the midnineteenth century, with an emphasis on the products which made up the bulk of the island’s agricultural production. The authors have organized most of the existing databases in the island’s archives and have also incorporated quantitative and qualitative material from their own research and that of other colleagues. Due to their quality and regularity, the data are among the richest known for pre-industrial Europe. These sources lead to some conclusions which link with recent debates in European economic history concerning the calculation of economic growth in economies for periods before statistics were kept. The text presents a methodological analysis covering almost 80 per cent of agricultural production of the island of Majorca and leaves conclusions to be supplemented by further studies of the manufacturing and service sectors

Els apareguts i el culte de les ànimes del Purgatori (segles XIV-XVII). Estudi i edició de textos catalans

Report for the scientific sojourn carried out at the Institut National d'Histoire de l'Art (INHA), France, from 2010 to 2012. It has focused on the analysis and editing of tales of human apparitions from the other world belonging to the Catalan culture or referring to it. We have studied and edited different versions of the process of Esperança Alegre (Lleida, 1500) and the Peregrinació del Venturós Pelegrí. These medieval works have been preserved in sources of the late sixteenth century or later. We have located a manuscript of the Esperança Alegre's tale, unknown to us at the beginning of this research (Biblioteca Nacional de España, ms. 1701), which differs from the version of ms. Baluze 238 of the Bibliothèque Nationale de France. The scribe of the ms. 1701 adds several paragraphs where considers the case as a diabolical phantasmagoria. About the Venturós Pelegrí, we have tried to establish firm criteria for the classification of many editions from the seventeenth to nineteenth centuries. We have been looking for printed books in the libràries of the world and we have made several requests for photographic reproductions, in order to classify undated editions by comparing woodcuts and other decorative elements. In the legend of Prince Charles of Viana (1421-1461), the appearances of his ghost are accompanied by rumors of his poisoning and of his sanctity. In addition, we have studied the cycles of masses for the souls in Purgatory linked to the hagiographies of St. Amadour and St. Vincent Ferrer, as well as the appearances described in L'Ànima d’Oliver of Francesc Moner, in the Carmelite chronicles of Father John of St. Joseph (1642-1718) and in some folktales collected from the eighteenth to the twentieth century. All this have allowed us to verify the evolution of certain cultural paradigms since the Middle Ages to the present.

Biopsia percutánea de la interfase protésica: técnica para el aislamiento preoperatorio del microorganismo patógeno en casos de infección periprotésica crónica con aspirado articular “seco”.

El objetivo de este estudio es determinar la valía diagnóstica de una biopsia de interfase protésica (BIP) preoperatoria para aislar la bacteria en casos de infección periprotésica crónica con aspirado articular “seco”. Para ello se realizó una revisión retrospectiva de 24 pacientes. Los resultados de los cultivos de la BIP se compararon con los resultados de los cultivos de las muestras intraoperatorias. La sensibilidad fue de un 88,2%, la especificidad del 100%, el valor predictivo positivo del 100% y el valor predictivo negativo del 77,9%. La eficacia global fue del 91,6%. La BIP resultó una prueba efectiva.

Papel del hierro endovenoso para el manejo de la anemia preoperatoria en cirugía ortopédica mayor dentro de un programa de ahorro de sangre

Objetivos La anemia preoperatoria es frecuente en cirugía ortopédica mayor y es un factor predictivo de transfusión y de peor evolución postoperatoria. El objetivo de este estudio es evaluar la utilidad y seguridad del hierro endovenoso como tratamiento de la anemia preoperatoria y ferropenia en cirugía ortopédica mayor, y valorar la respuesta según el hierro utilizado y/o el tipo de anemia de acuerdo con el algoritmo de actuación de nuestro programa de ahorro de sangre. Material y métodos Análisis retrospectivo de una base de datos prospectiva de los pacientes programados para prótesis total de cadera (PTC) y de rodilla (PTR), en los últimos 5 años. Utilizamos la base de datos online PAS (Programa de Ahorro de Sangre) en www.awge.org que incluye: edad, sexo, peso, ASA, metabolismo del hierro, evolución de la hemoglobina (Hb), efectos adversos y transfusión. Resultados Se incluyeron en el PAS 3.488 pacientes de los cuales 612 (17,5%) presentaban anemia preoperatoria y 169 (27,6%) fueron tratados con hierro endovenoso (HE) De los pacientes tratados con HE (169), 35 recibieron hierro sacarosa (HS) y 134 hierro carboximaltosa (HCM). De acuerdo con el algoritmo de tratamiento, 101 lo recibieron por anemia por déficit de hierro (ADH), 26 por ferropenia sin anemia (DH), 21 por anemia de proceso crónico (APC) y 21 en otros tipos de anemia. El incremento de la Hb fue de 1 ± 09 g/dl en el DH, de 1.7± 1 g/dl en ADH y de 2.1 ± 1 g/dl en APC y otras anemias (P<0.001). El grupo del HCM la adherencia al tratamiento fue superior y necesitaron menos visitas (p<0.001). Los efectos adversos fueron leves y similares en ambos grupos. Conclusiones El hierro endovenoso (HS o HCM) es un tratamiento eficaz y seguro de la anemia preoperatoria en cirugia ortopédica mayor, aunque el HCM tiene la ventaja de conseguir el mismo resultado con sólo una administración.

The Employment Precariousness Scale (EPRES): psychometric properties of a new tool for epidemiological studies among waged and salaried workers

Background: Despite the fact that labour market flexibility has resulted in an expansion of precarious employment in industrialized countries, to date there is limited empirical evidence about its health consequences. The Employment Precariousness Scale (EPRES) is a newly developed, theory-based, multidimensional questionnaire specifically devised for epidemiological studies among waged and salaried workers. Objective: To assess acceptability, reliability and construct validity of EPRES in a sample of waged and salaried workers in Spain. Methods: Cross-sectional study, using a sub-sample of 6.968 temporary and permanent workers from a population-based survey carried out in 2004-2005. The survey questionnaire was interviewer administered and included the six EPRES subscales, measures of the psychosocial work environment (COPSOQ ISTAS21), and perceived general and mental health (SF-36). Results: A high response rate to all EPRES items indicated good acceptability; Cronbach’s alpha coefficients, over 0.70 for all subscales and the global score, demonstrated good internal consistency reliability; exploratory factor analysis using principal axis analysis and varimax rotation confirmed the six-subscale structure and the theoretical allocation of all items. Patterns across known groups and correlation coefficients with psychosocial work environment measures and perceived health demonstrated the expected relations, providing evidence of construct validity. Conclusions: Our results provide evidence in support of the psychometric properties of EPRES, which appears to be a promising tool for the measurement of employment precariousness in public health research.

Association between GIS-based exposure to urban air pollution during pregnancy and birth weight in the INMA Sabadell Cohort

Background: There is growing evidence that traffic-related air pollution reduces birth weight. Improving exposure assessment is a key issue to advance in this research area.Objective: We investigated the effect of prenatal exposure to traffic-related air pollution via geographic information system (GIS) models on birth weight in 570 newborns from the INMA (Environment and Childhood) Sabadell cohort.Methods: We estimated pregnancy and trimester-specific exposures to nitrogen dioxide and aromatic hydrocarbons [benzene, toluene, ethylbenzene, m/p-xylene, and o-xylene (BTEX)] by using temporally adjusted land-use regression (LUR) models. We built models for NO2 and BTEX using four and three 1-week measurement campaigns, respectively, at 57 locations. We assessed the relationship between prenatal air pollution exposure and birth weight with linear regression models. We performed sensitivity analyses considering time spent at home and time spent in nonresidential outdoor environments during pregnancy.Results: In the overall cohort, neither NO2 nor BTEX exposure was significantly associated with birth weight in any of the exposure periods. When considering only women who spent < 2 hr/day in nonresidential outdoor environments, the estimated reductions in birth weight associated with an interquartile range increase in BTEX exposure levels were 77 g [95% confidence interval (CI), 7–146 g] and 102 g (95% CI, 28–176 g) for exposures during the whole pregnancy and the second trimester, respectively. The effects of NO2 exposure were less clear in this subset.Conclusions: The association of BTEX with reduced birth weight underscores the negative role of vehicle exhaust pollutants in reproductive health. Time–activity patterns during pregnancy complement GIS-based models in exposure assessment.

Genetic characterization of the ABO blood group in Neandertals

Background: The high polymorphism rate in the human ABO blood group gene seems to be related to susceptibility to different pathogens. It has been estimated that all genetic variation underlying the human ABO alleles appeared along the human lineage, after the divergence from the chimpanzee lineage. A paleogenetic analysis of the ABO blood group gene in Neandertals allows us to directly test for the presence of the ABO alleles in these extinct humans. Results: We have analysed two male Neandertals that were retrieved under controlled conditions at the El Sidron site in Asturias (Spain) and that appeared to be almost free of modern human DNA contamination. We find a human specific diagnostic deletion for blood group O (O01 haplotype) in both Neandertal individuals. Conclusion: These results suggest that the genetic change responsible for the O blood group in humans predates the human and Neandertal divergence. A potential selective event associated with the emergence of the O allele may have therefore occurred after humans separated from their common ancestor with chimpanzees and before the human-Neandertal population divergence.

On codes, matroids, and secure multiparty computation from linear secret-sharing schemes

Error-correcting codes and matroids have been widely used in the study of ordinary secret sharing schemes. In this paper, the connections between codes, matroids, and a special class of secret sharing schemes, namely, multiplicative linear secret sharing schemes (LSSSs), are studied. Such schemes are known to enable multiparty computation protocols secure against general (nonthreshold) adversaries.Two open problems related to the complexity of multiplicative LSSSs are considered in this paper. The first one deals with strongly multiplicative LSSSs. As opposed to the case of multiplicative LSSSs, it is not known whether there is an efficient method to transform an LSSS into a strongly multiplicative LSSS for the same access structure with a polynomial increase of the complexity. A property of strongly multiplicative LSSSs that could be useful in solving this problem is proved. Namely, using a suitable generalization of the well-known Berlekamp–Welch decoder, it is shown that all strongly multiplicative LSSSs enable efficient reconstruction of a shared secret in the presence of malicious faults. The second one is to characterize the access structures of ideal multiplicative LSSSs. Specifically, the considered open problem is to determine whether all self-dual vector space access structures are in this situation. By the aforementioned connection, this in fact constitutes an open problem about matroid theory, since it can be restated in terms of representability of identically self-dual matroids by self-dual codes. A new concept is introduced, the flat-partition, that provides a useful classification of identically self-dual matroids. Uniform identically self-dual matroids, which are known to be representable by self-dual codes, form one of the classes. It is proved that this property also holds for the family of matroids that, in a natural way, is the next class in the above classification: the identically self-dual bipartite matroids.

La terminología hoy: replanteamiento o diversificación

Cet article présente d’abord le panorama actuel de la terminologie du point de vue théorique, quise caractérise aujourd’hui par une grande diversité d’approches comme résultat de l’apparition de nouvelles nécessités au cours des dernières années, qui ont abouti à des usages terminologiques aussi très diverses. Comme réponse à cette nouvelle situation, les auteurs présentent une esquisse d’une proposition pour unenouvelle conception de la terminologie, qui essai d’intégrer des apports du côté linguistique, cognitive et sociale; cette nouvelle approche théorique présente aussi des conséquences importantes sur le planméthodologique et pratique.

La terminologia i la traducció, una interrelació en evolució

La interrelació entre traducció i terminologia es pot descriure des de diferents perspectives. La primera és el paper de la terminologia com a eina cognitiva en l'adquisició del coneixement especialitzat per part del traductor. La segona es refereix a la necessitat permanent de crear nous recursos terminogràfics i actualitzar-ne els existents, pensats per i per a a traductors competents i autònoms en la gestió de la terminologia. És lícit, doncs, considerar el traductor no només usuari de terminologia, sinó també, agent actiu en terminologia.

Representar l’univers referencial: estratègies per a la visibilitat dels processos de socialització a la universitat

Sota el nom d’Univers de la Comunicació Audiovisual definim un projecte que té, com a element més significatiu, la representació visual d’un mapa conceptual format per les referències (autors, obres i conceptes) que tant el professorat com l’alumnat hem considerat més significatives del nostre camp d’estudi. L’ Univers... es defineix també com un espai a internet on podem trobar, a més del mapa conceptual, un espais de debat i un conjunt defitxes que interrelacionen el mapa amb les assignatures dels estudis.El projecte busca apropar i potenciar la participació de l’alumnat en el reconeixement ila lectura crítica del seu autors, obres i conceptes de referència, donant visibilitat al procés ifent-lo públic. Des de l’Univers... proposem una nova aproximació a la competència general descrita com a capacitat crítica de naturalesa multidisciplinària que doti a l’alumnat de capacitat derecerca acadèmica i aplicada. Entenem aquesta capacitació crítica com un procés que vadesenvolupant l’alumnat durant tot el grau. Procés que suposa, en una dimensió individual, assolir objectius com el reconeixement, localització i configuració d’un marc referencial propi, i que permet, en la seva dimensió col·lectiva, participar en la definició i concreció d’un marccomú. Amb aquesta aproximació busquem ubicar les competències generals en el centre del procés de socialització que suposa l’etapa de formació universitària, dotant-les d’un entorn propi que, alhora, es relaciona amb l’espai de les assignatures. El projecte Univers... ha estat desenvolupat pel Deganat i la Unitat de Suport a la Innovació Docent dels Estudis de Comunicació Audiovisual de la Universitat Pompeu Fabra durant el curs acadèmic 2006/2007.

Coupling digital and physical worlds in an AR magic show performance: lessons learned

“Magic for a Pixeloscope” is a one hour show conceived to berepresented in a theater scenario that merges mixed and augmented reality (MR/AR) and full-body interaction with classical magic to create new tricks. The show was conceived by an interdisciplinary team composed by a magician, twointeraction designers, a theater director and a stage designer. Themagician uses custom based hardware and software to createnew illusions which are a starting point to explore new languagefor magical expression. In this paper we introduce a conceptualframework used to inform the design of different tricks; weexplore the design and production of some tricks included in theshow and we describe the feedback received on the world premiere and some of the conclusions obtained.
