In this article, Rosa Cabré discusses Marçal¿s novel and illustrates how, according to the author, the desire of love, which is a source of pleasure often accompanied by guilt and distress, can lead to the creation or the illusion of an absolute beauty, like poetry. She explains in what way the mirror and the mask, recurring motifs in Marçal¿s work, symbolise identity and ¿otherness¿ and how these unite the real and the symbolic level. The novel contains an infinite number of mirrors, both external and internal ones, which enable the characters to see themselves reflected. This reflection is linked to feminity and to the possibilities of discovering one¿s own identity.

The article presents and discusses long-run series of per capita GDP and life expectancy for Italy and Spain (1861-2008). After refining the available estimates in order to make them comparable and with the avail of the most up-to-date researches, the main changes in the international economy and in technological and sociobiological regimes are used as analytical frameworks to re-assess the performances of the two countries; then structural breaks are searched for and Granger causality between the two variables is investigated. The long-run convergence notwithstanding, significant cyclical differences between the two countries can be detected: Spain began to modernize later in GDP, with higher volatility in life expectancy until recent decades; by contrast, Italy showed a more stable pattern of life expectancy, following early breaks in per capita GDP, but also a negative GDP break in the last decades. Our series confirm that, whereas at the early stages of development differences in GDP tend to mirror those in life expectancy, this is no longer true at later stages of development, when, if any, there seems to be a negative correlation between GDP and life expectancy: this finding is in line with the thesis of a non-monotonic relation between life expectancy and GDP and is supported by tests of Granger causality.

El propòsit d’aquest estudi és analitzar quin és l’índex d’efectivitat en diferents situacions a pilota aturada (penals, faltes sense barrera i córners) en el futbol platja dins el context d’equips amateurs que participen en els tornejos de Blanes i Tossa de Mar. A l’hora de realitzar-lo he tingut en compte una sèrie de variables, com ara la precisió del colpeig, el tipus de colpeig, la superfície de contacte o la situació inicial de la pilota, és a dir, des d’on provenia la trajectòria inicial d’ aquesta, tot comprovant també com canvien els resultats en funció de la zona i del costat que es realitza el remat. Respecte els resultats, aquests demostren que l’índex d’efectivitat en aquest tipus d’accions és més baix en relació amb altres esports semblants com el futbol i el futbol sala.

L’objectiu del present estudi va consistir en estudiar el percentatge de gols a pilota aturada de la Lliga BBVA i la Premier League, establint el percentatge d’efectivitat de cadascuna d’elles. A més, es volia analitzar la freqüència de les diferents tipus d’accions a pilota aturada i substituir el terme estratègia per accions a pilota aturada. Amb aquest objectiu es van analitzar 80 partits disputats per equips de futbol professional en la temporada 2012-13 de la Lliga BBVA i la Premier League mitjançant l’anàlisi de vídeos. Les variable dependent era la consecució o no del gol, tenint com a variables independents 4 tipus d’accions a pilota aturada: tirs lliures directes, tirs lliures indirectes, córners i penals. Els resultats indiquen un major número de gols provinents d’accions a pilota aturada en la Lliga BBVA que en la Premier League, 29,8% per un 23,4% respectivament. Tot i això, s’ha comprovat com els percentatges d’efectivitat són pràcticament idèntics: 4,54% a la Lliga BBVA i 4,58% a la Premier League. Finalment, s’ha identificat el córner com l’acció que més es produeix en el joc, seguit de les faltes directes, els penals i les faltes indirectes.

L’aprenentatge de la lectoescriptura és complex. Aprendre a llegir i escriure implica dominar moltes habilitats. A l’escola habitualment es treballa de forma mecànica i poc significativa. L’objectiu d’aquest projecte és conèixer si les lletres de confegir de Maria Montessori encara tenen vigència en l’actualitat. En aquest sentit, s’ha valorat el racó on hi ha aquest material, ja existent a l’escola, per posteriorment fer una proposta de millora i desenvolupar-la dins el marc d’una aula de P5. A través d’algunes situacions reals d’aula volem il·lustrar les possibilitats de la nostra proposta. L’experiència realitzada amb infants de l’últim curs d’Educació Infantil indica que treballar el procés de lectoescriptura amb aquest material és una bona eina per atendre a la diversitat existent a les aules actuals.

Neuropathic pain is a clinical manifestation of nerve injury difficult to treat even with potent analgesic compounds. Here, we used different lines of genetically modified mice to clarify the role played by CB2 cannabinoid receptors in the regulation of the central immune responses leading to the development of neuropathic pain. CB2 knock-out mice and wild-type littermates were exposed to sciatic nerve injury, and both genotypes developed a similar hyperalgesia and allodynia in the ipsilateral paw. Most strikingly, knock-outs also developed a contralateral mirror image pain, associated with an enhanced microglial and astrocytic expression in the contralateral spinal horn. In agreement, hyperalgesia, allodynia, and microglial and astrocytic activation induced by sciatic nerve injury were attenuated in transgenic mice overexpressing CB2 receptors. These results demonstrate the crucial role of CB2 cannabinoid receptor in modulating glial activation in response to nerve injury. The enhanced manifestations of neuropathic pain were replicated in irradiated wild-type mice reconstituted with bone marrow cells from CB2 knock-outs, thus demonstrating the implication of the CB2 receptor expressed in hematopoietic cells in the development of neuropathic pain at the spinal cord.

In soccer, dead-ball moves are those in which the ball is returned to play from a stationary position following an interruption of play. The aim of this study was to analyse the effectiveness of one such dead-ball move, namely corner kicks, and to identify the key variables that determine the success of a shot or header following a corner, thereby enabling a model of successful corner kicks to be proposed. We recorded 554 corner kicks performed during the 2010 World Cup in South Africa and carried out a univariate, bivariate and multivariate analysis of the data. The results indicated that corners were of limited effectiveness in terms of the success of subsequent shots or headers. The analysis also revealed a series of variables that were significantly related to one another, and this enabled us to propose an explanatory model. Although this model had limited explanatory power, it nonetheless helps to understand the execution of corner kicks in practical terms.

This article introduces a new interface for T-Coffee, a consistency-based multiple sequence alignment program. This interface provides an easy and intuitive access to the most popular functionality of the package. These include the default T-Coffee mode for protein and nucleic acid sequences, the M-Coffee mode that allows combining the output of any other aligners, and template-based modes of T-Coffee that deliver high accuracy alignments while using structural or homology derived templates. These three available template modes are Expresso for the alignment of protein with a known 3D-Structure, R-Coffee to align RNA sequences with conserved secondary structures and PSI-Coffee to accurately align distantly related sequences using homology extension. The new server benefits from recent improvements of the T-Coffee algorithm and can align up to 150 sequences as long as 10 000 residues and is available from both http://www.tcoffee.org and its main mirror http://tcoffee.crg.cat.

En aquest article em referiré molt sumàriament a la fi lologia del dinou, mirant de relacionar-la amb tot el joc de paraules en Lewis Carrol, per tal d'establir-hi una trama correcta de (dis)continuïtats. El meu objectiu és considerar el Jabberwocky de Humpty Dumpty en el context de la feina i les descobertes de la moderna fi lologia. F. A. Wolf i J. Grimm condensen bona cosa dels experiments radicals i les troballes que tingueren lloc en aquells moments, que podríem contrastar amb les aventures textuals d'Alícia a l'altra banda de l'espill. Els llibres de l'altra banda necessiten intèrprets i cerquen la versió correcta, original, de la mateixa manera que la interpretació dels mots depèn d'un mètode fi able. Segurament Lewis Carroll com a jove fi lòleg era capaç de jugar bé amb aquelles troballes, entre un món que s'acabava i un altre que començava.

The emergence of chirality in enantioselective autocatalysis for compounds unable to transform according to the Frank-like reaction network is discussed with respect to the controversial limited enantioselectivity (LES) model composed of coupled enantioselective and non-enantioselective autocatalyses. The LES model cannot lead to spontaneous mirror symmetry breaking (SMSB) either in closed systems with a homogeneous temperature distribution or in closed systems with a stationary non-uniform temperature distribution. However, simulations of chemical kinetics in a two-compartment model demonstrate that SMSB may occur if both autocatalytic reactions are spatially separated at different temperatures in different compartments but coupled under the action of a continuous internal flow. In such conditions, the system can evolve, for certain reaction and system parameters, toward a chiral stationary state; that is, the system is able to reach a bifurcation point leading to SMSB. Numerical simulations in which reasonable chemical parameters have been used suggest that an adequate scenario for such a SMSB would be that of abyssal hydrothermal vents, by virtue of the typical temperature gradients found there and the role of inorganic solids mediating chemical reactions in an enzyme-like role.

[spa] A través de las siguientes páginas nos adentraremos en la diferencia abismal de dos sistemas de protección del empleo, España y Dinamarca, producto de una concepción y evolución distinta del Estado del bienestar surgido tras la Gran Depresión de los años 30 y la II Guerra Mundial. Las políticas de empleo danesas gozan de una gran estabilidad y eficacia desde la década de 1990. España, por el contrario, tiene una amalgama de políticas desordenada y caótica que pone su acento en los incentivos a la contratación. Mirarse en el espejo danés, de vez en cuando, es una buena idea.

The ability to recognize a shape is linked to figure-ground (FG) organization. Cell preferences appear to be correlated across contrast-polarity reversals and mirror reversals of polygon displays, but not so much across FG reversals. Here we present a network structure which explains both shape-coding by simulated IT cells and suppression of responses to FG reversed stimuli. In our model FG segregation is achieved before shape discrimination, which is itself evidenced by the difference in spiking onsets of a pair of output cells. The studied example also includes feature extraction and illustrates a classification of binary images depending on the dominance of vertical or horizontal borders.

Quan el 1602 els diputats ordenen una nova visura de les obres d'ampliació del Palau de la Generalitat, s'està de fet qüestionant la primitiva traça de Pere Blai. Hom posa en joc tot un seguit de categories, d'acord amb un nou estil visual d'arrel renaixentista que prima la mirada. En són requeriments: els costos econòmics, la visualització de l'edifici –valor de la imatge d'acord amb una intencionada representació del poder civil– i la seva individualització en el teixit urbà –d'aquí, el propòsit d'alliberar l'espai d'una plaça. El Memorial de 1603 s'insereix en una llarga i intricada seqüència. El document, d'interès pel cabal intrínsec d'informació projectual i constructiva, ho és també per a l'exegesi del model clàssic, del seu grau de comprensió i utilització al llindar del segle XVII en l'àmbit del Principat

Els humans som uns imitadors excel·lents. Som capaços d'imitar els moviments dels altres, les seves expressions i també els seus sentiments. Aquesta és la base de la literatura, la poesia, la música i el teatre, manifestacions culturals cent per cent humanes que ens fan vibrar com si allò que llegim, escoltem o veiem ho estiguéssim vivint realment nosaltres, en un procés d'imitació mental que fa que ens hi sentim reflectits [...].
