La crisi financera actual ha posat de manifest les conseqüències de no tractar correctament les fallides de mercat en el sector bancari. Aquestes fallides de mercat, que són un element intrínsec de la pròpia activitat bancària, són un element imprescindible per entendre els desequilibris que han desencadenat crisi.El treball analitza una de les fallides de mercat del sector bancari que més incidència ha tingut en el desenvolupament de la crisi financera actual: la asimetria informativa. L’objectiu de l’estudi és identificar els problemes de selecció adversa i risc moral que es van produir en els anys previs a la crisi bancaria i fer-ne unanàlisi detallat.La hipòtesi del treball és que la asimetria informativa impedeix al sector bancari assolir un equilibri Paretoeficient en absència d'una regulació adequada.Per donar una resposta satisfactòria a la nostra hipòtesi, cal demostrar que la multitud de distorsions que la asimetria informativa va generar tingueren un impacte significatiu en el desenvolupament de la crisi. Amb aquest objectiu, volem mostrar quines han estat les causes i conseqüències d'aquestes distorsions, per què s'han produït i com s’haguessin pogut evitar en un entorn de regulació adequada.L'estructura del treball és la següent: en primer lloc oferim el context històric que ha motivat aquest treball, és a dir, una breu explicació sobre les causes i conseqüències de la crisi econòmica, establint paral·lelismes amb els casos de asimetria informativa que tractem. En segon lloc, analitzem el paper que ha tingut laasimetria informativa en la crisi actual i les raons que ens indiquen que el seu impacte ha estat fonamentalpel desenvolupament de la crisi. En tercer lloc, oferim dos models econòmics, un d’ells d’elaboració pròpia, amb l'objectiu de, no només identificar els diversos problemes de asimetria informativa transcorreguts anteriorment a la crisi bancària, sinó també per donar-hi una resposta econòmicament viable i satisfactòria.En quart lloc, exposem les mesures reguladores que considerem que poden solucionar els diferents casos de asimetria informativa analitzats. Finalment, oferim les conclusions més rellevants del treball.

La inserció laboral és l'accés al mercat laboral, al món del treball, entenent per tal la consecució d'un treball. Des d"aquesta perspectiva s'entendria la inserció laboral com un fet puntual (Fernández, 1988; Figuera i Bisquerra, 1992; Pérez Escoda, 1996), en referència al «fet d'aconseguir una ocupació en un moment determinat, és a dir, un contracte laboral. La inserció laboral inclou tant la incorporació de la persona a un lloc de treball com el seu manteniment. Actualment, dintre de la problemàtica de l'atur i de la inserció, cal tenir en compte ambdós factors, ja que, a més de la dificultat per trobar un treball, l'altre gran problema resideix en la capacitat per mantenir-ho» (Romero et al., 2004).

The purpose of this article is to treat a currently much debated issue, the effects of age on second language learning. To do so, we contrast data collected by our research team from over one thousand seven hundred young and adult learners with four popular beliefs or generalizations, which, while deeply rooted in this society, are not always corroborated by our data.Two of these generalizations about Second Language Acquisition (languages spoken in the social context) seem to be widely accepted: a) older children, adolescents and adults are quicker and more efficient at the first stages of learning than are younger learners; b) in a natural context children with an early start are more liable to attain higher levels of proficiency. However, in the context of Foreign Language Acquisition, the context in which we collect the data, this second generalization is difficult to verify due to the low number of instructional hours (a maximum of some 800 hours) and the lower levels of language exposure time provided. The design of our research project has allowed us to study differences observed with respect to the age of onset (ranging from 2 to 18+), but in this article we focus on students who began English instruction at the age of 8 (LOGSE Educational System) and those who began at the age of 11 (EGB). We have collected data from both groups after a period of 200 (Time 1) and 416 instructional hours (Time 2), and we are currently collecting data after a period of 726 instructional hours (Time 3). We have designed and administered a variety of tests: tests on English production and reception, both oral and written, and within both academic and communicative oriented approaches, on the learners' L1 (Spanish and Catalan), as well as a questionnaire eliciting personal and sociolinguistic information. The questions we address and the relevant empirical evidence are as follows: 1. "For young children, learning languages is a game. They enjoy it more than adults."Our data demonstrate that the situation is not quite so. Firstly, both at the levels of Primary and Secondary education (ranging from 70.5% in 11-year-olds to 89% in 14-year-olds) students have a positive attitude towards learning English. Secondly, there is a difference between the two groups with respect to the factors they cite as responsible for their motivation to learn English: the younger students cite intrinsic factors, such as the games they play, the methodology used and the teacher, whereas the older students cite extrinsic factors, such as the role of their knowledge of English in the achievement of their future professional goals. 2 ."Young children have more resources to learn languages." Here our data suggest just the opposite. The ability to employ learning strategies (actions or steps used) increases with age. Older learners' strategies are more varied and cognitively more complex. In contrast, younger learners depend more on their interlocutor and external resources and therefore have a lower level of autonomy in their learning. 3. "Young children don't talk much but understand a lot"This third generalization does seem to be confirmed, at least to a certain extent, by our data in relation to the analysis of differences due to the age factor and productive use of the target language. As seen above, the comparably slower progress of the younger learners is confirmed. Our analysis of interpersonal receptive abilities demonstrates as well the advantage of the older learners. Nevertheless, with respect to passive receptive activities (for example, simple recognition of words or sentences) no great differences are observed. Statistical analyses suggest that in this test, in contrast to the others analyzed, the dominance of the subjects' L1s (reflecting a cognitive capacity that grows with age) has no significant influence on the learning process. 4. "The sooner they begin, the better their results will be in written language"This is not either completely confirmed in our research. First of all, we perceive that certain compensatory strategies disappear only with age, but not with the number of instructional hours. Secondly, given an identical number of instructional hours, the older subjects obtain better results. With respect to our analysis of data from subjects of the same age (12 years old) but with a different number of instructional hours (200 and 416 respectively, as they began at the ages of 11 and 8), we observe that those who began earlier excel only in the area of lexical fluency. In conclusion, the superior rate of older learners appears to be due to their higher level of cognitive development, a factor which allows them to benefit more from formal or explicit instruction in the school context. Younger learners, however, do not benefit from the quantity and quality of linguistic exposure typical of a natural acquisition context in which they would be allowed to make use of implicit learning abilities. It seems clear, then, that the initiative in this country to begin foreign language instruction earlier will have positive effects only if it occurs in combination with either higher levels of exposure time to the foreign language, or, alternatively, with its use as the language of instruction in other areas of the curriculum.

Aquest treball és un aprofundiment teòric sobre la mort en la realitat actual i un anàlisi de com es tractada des del Treball Social. La mort forma part de la vida i vivim en una societat on hi ha la percepció de que es fa negació de la mateixa. A través d'aquest projecte he volgut esbrinar si aquest fet, es veu reflexat en els recursos amb els que els/les treballadors/es socials fan la seva tasca amb persones properes a la mort. La visió de la mort en l’actualitat té moltes definicions i també està lligada al fet de com s'ha viscut al llarg de la història

Este trabajo constituye una aproximación al vibrato en el violín desde diversos puntos de vista. En primer lugar, abordaremos la cuestión histórica: cuándo aparece el vibrato, cómo evoluciona a lo largo de la historia y por qué se ha convertido en un recurso tan explotado hoy en día. A continuación, trataremos el vibrato como un fenómeno acústico y describiremos sus principales parámetros de estudio. Por último, plantearemos el aspecto puramente técnico del vibrato, aportando ejercicios para su correcto desarrollo. El objetivo final no es sólo conocer con mayor profundidad la historia y las características de este recurso, sino también entender su funcionamiento técnico y qué método de estudio se ha de seguir para sacar el máximo partido de él. La metodología del trabajo se basa en la lectura y puesta en práctica del legado de diversos violinistas y pedagogos que han tratado el tema a lo largo de la historia.

En el presente trabajo se diseñan tres modelos DEA a partir de un sistema de producción cuyos componentes están colocados en un arreglo en serie que se integran verticalmente hacia adelante. El primer modelo busca optimizar los beneficios del sistema agregado, así como la mejora de los mismos en cada uno de los subsistemas. En el segundo de los modelos, además del objetivo anterior, se incluyen restricciones de transferencia de los recursos específicos asociados a cada subsistema, y en el tercer modelo se estima el intervalo de variación para los precios de transferencia de los inputs intermedios entre ambos subsistemas. Los modelos han sido programados y simulados en el software GAMS a partir de datos generados por una función de producción Cobb-Douglas para los inputs intermedios y los outputs finales.

Este trabajo explora la formación de grupos estratégicos en el Sector Bancario Español, a partir de una definición alternativa de grupo estratégico (GE). Un GE se define como un conjunto de empresas capaces de responder del mismo modo a perturbaciones. La capacidad de respuesta, o capacidad de adaptar la estrategia competitiva, se define a partir de las relaciones marginales (RM) entre las variables estratégicas (la pendiente de la frontera en un punto), y sirve de base para examinar la presencia de barreras a la movilidad. El Análisis Envolvente de Datos (DEA) es la herramienta utilizada para el cómputo de las RM, aunque su uso genera dos problemas que son solucionados en este trabajo; la multiplicidad de RM para las empresas situadas en la frontera (líderes estratégicos), y la imposibilidad de encontrar RM para las empresas situadas por debajo de la misma (seguidores estratégicos).
