En aquest treball es presenten les dades referents a la Cova Colomera (Sant Esteve de la Sarga, Pallars Jussà) durant el Neolític cardial final. A partir de diferents sondejos duts a terme des de l'any 2005, s'ha pogut observar la varietat d'usos i funcionalitats del jaciment en moments potencialment sincrònics. Per una banda,una zona on predominen les estructures de caire domètic (fogars, fosses i forats de pal)que ens mostren les dades entorn a l'hàbitat al jaciment; i per altra banda, un gran sector de la cavitat dedicat a l'estabulació dels ramats amb sediments de tipus fumier i probablement també a l'emmagatzematge. Tot això succeix en unes datacions d'entre 6180 +/- 40 i 6020 +/- 510BP. Aquestes dades es contextualitzen amb les d'altres jaciments de la zona pirinenca, un àmbit que sempre ha estat definit en la bibliografia com un espai de pas entre diferents biòtops ecològics, de les plantes fèrtils a les pastures de l'estiu.

N = 1 designs imply repeated registrations of the behaviour of the same experimental unit and the measurements obtained are often few due to time limitations, while they are also likely to be sequentially dependent. The analytical techniques needed to enhance statistical and clinical decision making have to deal with these problems. Different procedures for analysing data from single-case AB designs are discussed, presenting their main features and revising the results reported by previous studies. Randomization tests represent one of the statistical methods that seemed to perform well in terms of controlling false alarm rates. In the experimental part of the study a new simulation approach is used to test the performance of randomization tests and the results suggest that the technique is not always robust against the violation of the independence assumption. Moreover, sensitivity proved to be generally unacceptably low for series lengths equal to 30 and 40. Considering the evidence available, there does not seem to be an optimal technique for single-case data analysis

L"últim mes de maig, al IV Simposi de Filologia Valenciana -en honor de Joan Veny- organitzat pel Departament de Filologia Catalana de la Universitat de València, vaig exposar oralment la meua part en l"homenatge al mestre de Campos. Ecologia i caracterització dels parlars xurros fou el títol que els organitzadors em van proposar, el mateix que vaig servar per a la versió escrita destinada a les actes corresponents. Un parell de mesos després vaig rebre de l"amic Josep Martines l"encàrrec de col·laborar en el present número monogràfic sobre les relacions entre l"aragonès i el català. Encara en premsa aquella contribució sobre aspectes generals dels parlars castellanoaragonesos de l"interior valencià, n"ofereixo ara (desembre de 2000) una altra que pretén desenvolupar algunes qüestions particulars d"aquest món lingüístic de frontera.

Different asymmetries between expansion and contraction (radial motions) have been reported in the literature. Often these patterns have been regarded as implying different channels for each type of radial direction (outward versus inwards) operating at a higher level of visual motion processing. In two experiments (detection and discrimination tasks) we report reaction time asymmetries between expansion and contraction. Power functions were fitted to the data. While an exponent of 0.5 accounted for the expansion data better, a value of unity yielded the best fit for the contraction data. Instead of interpreting these differences as corresponding to different higher order motion detectors, we regard these findings as reflecting the fact that expansion and contraction tap two distinct psychophysical input channels underlying the processing of fast and slow velocities respectively.

This article focuses on the study of the treatment of eroticism in some of the poetic compositions from Francesc Fontanella (1622-1682/3). The paper studies fiften literary epistles whisch Fontanella dedicated to the nuns of the convent of Els Àngels and Jerusalem of Barcelona during the 1640s. It is divided into two parts; to first, the compositions under study are identified and presented briefly, and some issues related to the transmission of these textes are clarified. The second part discusses in detail all erotic references present in text. This analysis, on one hand, allows to present an interpretation of the meaning of the whole story contained in the letters. Moreover, it allows to present a characterization of the erotic vision of Fontanella. This is done by comparing this vision with the usual one at the time of baroque, as well as by analyzing the rhetorical strategies and the representation strategies that the author uses in the treatment of eroticism

Al llarg del segle XVI es produí de manera lenta i heterogènia la progressiva introducció al Principat de les formes artístiques del Renaixement italià. Tradicionalment, a Catalunya, igual que a la resta del territori europeu, havia estat la noblesa, com a estament més proper al poder reial, la principal protagonista en el procés de comitència de les obres de més envergadura, moltes d"elles plantejades amb un sentit àulic que pretenia manifestar el predomini polític i econòmic de què havia gaudit d"antuvi aquest segment de la societat. Tanmateix, amb l"arribada a casa nostra dels nous corrents artístics renaixentistes es produí una certa inflexió en aquesta tendència, i hom pot observar com, a la fi del segle XVI i, sobretot, al llarg del segle XVII, aparegueren en l"escena del mercat artístic alts funcionaris reials, magistrats i juristes que, adherits al modern corrent de pensament humanista, dugueren a terme un important exercici de promoció i finançament d"empreses arquitectòniques, escultòriques i pictòriques seguidores dels preceptes renaixentistes. El present estudi analitza en quins termes es produí aquest relleu de patrocini artístic i repassa alguns casos ben emblemàtics.

La puntuación ha evolucionado a lo largo de la historia, no solo en cuanto al número de signos, sino también con respecto a su función de guía en la (re)presentación y el procesamiento del texto. El objetivo del presente artículo es discutir la pragmática de la puntuación en los principales modos de comunicación mediada por ordenador. Mi propuesta consiste en considerar que las nuevas formas escritas de interacción mediada por ordenador situadas en el polo de la inmediatez comunicativa han dado lugar a un particular sistema de puntuación metarrepresentativa que compite con los códigos de puntuación tanto retórico como gramatical.

The paper discusses the problem of the literary genre of the Crónica sarracina from a peninsular and european points of view. It is considerer through the prism of a new kind of fiction, related to history and an incipient realism, which grows up along the 15th century. Moreover, it reveals new fragments inspired by Pedro de Corral from the catalan version of Seneca’s tragedies and from the Libro de los doce sabios

In the current study, we evaluated various robust statistical methods for comparing two independent groups. Two scenarios for simulation were generated: one of equality and another of population mean differences. In each of the scenarios, 33 experimental conditions were used as a function of sample size, standard deviation and asymmetry. For each condition, 5000 replications per group were generated. The results obtained by this study show an adequate type error I rate but not a high power for the confidence intervals. In general, for the two scenarios studied (mean population differences and not mean population differences) in the different conditions analysed, the Mann-Whitney U-test demonstrated strong performance, and a little worse the t-test of Yuen-Welch.

Se entrenó a unas ratas a encontrar una plataforma invisible definida por una configuración de dos objetos en la mitad de los ensayos y por una segunda configuración de dos objetos en la otra mitad. Los objetos estaban espaciados alrededor del borde de la piscina. Las dos configuraciones se presentaron con la misma frecuencia cada día, entremezcladas semi-al azar. En el Experimento 1, las configuraciones de las ratas fueron A y B (configuración 1), y B y C (configuración 2). B era un objeto común a ambas configuraciones. Al final de esta fase los animales recibieron ensayos de prueba en los que se colocaba a una rata en la piscina sin la plataforma y se registraba el tiempo que pasaba en el cuadrante de la plataforma. Los animales tuvieron ensayos de prueba con las configuraciones del entrenamiento, con los objetos por separado, y con una nueva configuración, A y C (una prueba de integración). Tanto ante las configuraciones del entrenamiento como en presencia de B, las ratas pasaron una cantidad de tiempo sustancial buscando la plataforma en el cuadrante de la plataforma; no se obtuvo ningún otro efecto en las otras pruebas. En el Experimento 2 se introdujeron varios cambios metodológicos y se replicaron los principales resultados del Experimento 1. Concluimos que tras un entrenamiento configuracional como el empleado, la navegación de las ratas hacia una plataforma invisible estuvo controlada por un aprendizaje elemental, por B.

Rodrigo, Chamizo, McLaren, & Mackintosh (1997) demonstrated the blocking effect in a navigational task using a swimming pool: rats initially trained to use three landmarks (ABC) to find an invisible platform learned less about a fourth landmark (X) added later than did rats trained from the outset with these four landmarks (ABCX). The aim of the experiment reported here was to demonstrate unblocking using a similar procedure as in the previous work. Three groups of rats were initially trained to find an invisible platfom in the presence of three landmarks: ABC for the Blocking and Unblocking groups and LMN for the Control group. Then, all animals were trained to find the platform in the presence of four landmarks, ABCX. In this second training, unlike animals in the Blocking group to which only a new landmark (X) was added in comparison to the first training, the animals in the Unblocking group also had a change in the platform position. In the Control group, both the four landmarks and the platform position were totally new at the beginning of this second training. As in Rodrigo et al. (1997) a blocking effect was found: rats in the Blocking group learned less with respect to the added landmark (X) than did animals in the Control group. However, rats in the Unblocking group learned about the added landmark (X) as well as did animals in the Control group. The results are interpreted as an unblocking effect due to a change in the platform position between the two phases of training, similarly to what is normal in classical conditioning experiments, in which a change in the conditions of reinforcement between the two training phases of a blocking design produce an attenuation or elimination of this effect. These results are explained within an error-correcting connectionist account of spatial navigation (McLaren, 2002).
