Interpretació amb baixó de les Lamentacions a la Mallorca dels segles XVIII i XIX

Aquest treball es centra en les lamentacions de Setmana Santa escrites a Mallorca durant els segles XVIII i XIX i el possible ús del baixó en la seva execució. La recerca sobretot te un objectiu pràctic: aquest estudi permetrà fer una proposta d’interpretació amb el baixó d’una de les lamentacions monòdiques trobada a la Catedral de Mallorca a partir de les informacions que es desprenen d’aquest i d’altres contextos similars.

De Francisco a Marco Antonio Aldana pasando por Gaspar

It is traditionally considered that the «Aldana», whom Gaspar Gil Polo praises at the end of his «Canto de Turia» (1564), was Francisco de Aldana, the «divino». It is nonetheless more probable that it was in fact rather the Valencian poet, Marco Antonio Aldana, almost forgotten today, but very much in the public eye within the cultivated circles of the end of the sixteenth century Valencia

Reduction of the Ant Mandible Gap Range After Biotic Homogenization Caused by an Ant Invasion (Hymenoptera: Formicidae)

After most of the native ant species are displaced by the Argentine ant invasion, it is probable that some ecological processes carried out by natives are not replaced. In some cases this could be due to a morphological difference between the Argentine ant and the displaced native ants. The significant decrease in ant richness after the invasion (only two species detected in the invaded zones vs. 25 species in surrounding non-invaded zones) implies a drastic reduction in the ant mandible gap range (the mandible gap spectra of all the ant species in a community) in the invaded zones. This reduction could explain why some roles that were previously carried out by the displaced native species are not performed by the invasive species. This could be due to a functional inability to carry out these activities. The mandible gap waspositively correlated with the ant body mass in the 26 ant species considered. The functional inability hypothesis could be applied to other invasive ants as well as to the Argentine ant

Comprehension of passives in Persian speaking children with ASD : an investigation of grammar in autism

Most research on the underlying causes of social and communicative impairment in autism spectrum disorders (ASD) has been devoted to pragmatic aspects of language. The present research is exploring the syntactic knowledge as a probable underlying mechanism of language deficit in ASD. Three groups comprising high-functioning ASD, low-functioning ASD, and typically developing 5-year-old Persian-speaking children were tested on comprehension of passive sentences. Results suggest that while low-functioning children with ASD might be impaired in the area of grammar, high-functioning children with ASD are not. The new results are compared to those of two recent studies on comprehension of passives in Greek-speaking and English-speaking subjects with ASD (Perovic et al., 2007; Terzi, et al., to appear).

La población infantil de Barcelona (1898-1961): una evaluación de su estado nutricional a partir de estadísticas antropométricas

En los ejercicios de evaluación de la denominada “penalización urbana”, la mortalidad infantil y juvenil suele ser uno o de los indicadores más habituales. Disponer de indicadores relativos a sus condiciones de salud es más difícil. Una opción son los datos antropométricos. Este tipo de información abunda para las poblaciones adultas –especialmente las masculinas enroladas en los ejércitos- pero es más escasa para las infantiles. El propósito de este trabajo es contribuir al conocimiento de las condiciones de salud de este grupo de la población barcelonesa durante algo más de la primera mitad del siglo XX, a partir del estudio de un conjunto de 9 estadísticas antropométricas publicadas entre 1900 y 1961. A través de una reconstrucción estadística, mediante el empleo de las Tablas de Crecimiento de la población infantil española elaboradas por M. Hernández, E Sánchez y B.Sobradillo en 1995, se han estandarizado las tallas y comparado los Indices de Masa Corporal calculados a partir de las medidas publicadas. Los principales resultados son: a) La presencia de diferentes pautas en las trayectorias seculares de crecimiento de niños y niñas. El crecimiento de las tallas entre los niños fue de 1,09 cm por decenio entre 1898 y 1945 y de 1,40 entre 1945 y 1961. Mientras que en el caso de las niñas entre 1898 y 1945 fue de 0,14 cm por decenio para aumentar a 2,18 entre 1945 y 1981. b) Las diferencias sociales en los indicadores antropométricos persisten a lo largo del periodo estudiado c) Los porcentajes de población infantil con probable malnutrición se situaron en torno al 24 por ciento para las generaciones nacidas entre 1885 y 1940, para ir descendiendo de forma irreversible en las nacidas a partir de 1950. De este modo en la década años setenta del siglo XX no parece existir evidencia de tal estado en la población infantil barcelonesa.

Effects of cobalt-chromium everolimus eluting stents or bare metal stent on fatal and non-fatal cardiovascular events: patient level meta-analysis

Objectives: To examine the safety and effectiveness of cobalt-chromium everolimus eluting stents compared with bare metal stents. Design: Individual patient data meta-analysis of randomised controlled trials. Cox proportional regression models stratified by trial, containing random effects, were used to assess the impact of stent type on outcomes. Hazard ratios with 95% confidence interval for outcomes were reported. Data sources and study selection: Medline, Embase, the Cochrane Central Register of Controlled Trials. Randomised controlled trials that compared cobalt-chromium everolimus eluting stents with bare metal stents were selected. The principal investigators whose trials met the inclusion criteria provided data for individual patients. Primary outcomes: The primary outcome was cardiac mortality. Secondary endpoints were myocardial infarction, definite stent thrombosis, definite or probable stent thrombosis, target vessel revascularisation, and all cause death. Results: The search yielded five randomised controlled trials, comprising 4896 participants. Compared with patients receiving bare metal stents, participants receiving cobalt-chromium everolimus eluting stents had a significant reduction of cardiac mortality (hazard ratio 0.67, 95% confidence interval 0.49 to 0.91; P=0.01), myocardial infarction (0.71, 0.55 to 0.92; P=0.01), definite stent thrombosis (0.41, 0.22 to 0.76; P=0.005), definite or probable stent thrombosis (0.48, 0.31 to 0.73; P<0.001), and target vessel revascularisation (0.29, 0.20 to 0.41; P<0.001) at a median follow-up of 720 days. There was no significant difference in all cause death between groups (0.83, 0.65 to 1.06; P=0.14). Findings remained unchanged at multivariable regression after adjustment for the acuity of clinical syndrome (for instance, acute coronary syndrome v stable coronary artery disease), diabetes mellitus, female sex, use of glycoprotein IIb/IIIa inhibitors, and up to one year v longer duration treatment with dual antiplatelets. Conclusions: This meta-analysis offers evidence that compared with bare metal stents the use of cobalt-chromium everolimus eluting stents improves global cardiovascular outcomes including cardiac survival, myocardial infarction, and overall stent thrombosis.

Tropezando dos veces con la misma piedra: Quiebra de autopistas de peaje y costes para contribuyentes y usuarios

Este trabajo analiza la distribución de los riesgos en los contratos de colaboración público-privada en el sector de las autopistas de peaje y cuáles han sido las garantías otorgadas a lo largo del tiempo. Aunque se observa una mejor identificación y distribución de algunos riesgos progreso tecnológico y demanda, y un cambio en la asignación de garantías financieras, existen aún numerosos aspectos que dificultan el devenir de la industria. El declive general del tráfico aforado en todas las autopistas de peaje como consecuencia de la crisis, la construcción de vías alternativas y los costosos procesos expropiatorios de distintas concesionarias han generado importantes pérdidas en las nuevas concesiones, hasta el momento parcialmente sufragadas mediante recursos públicos. El debate sobre la solución a la crisis del sector sigue abierto, incluyendo un probable proceso de nacionalización.
