La recerca sobre la diversitat lingüística aportada per la immigració a Catalunya topa amb diversos problemes. En aquest article se¿n repassen alguns: el caràcter de constructe cultural del concepte de llengua, les ideologies lingüístiques tant d¿investigadors com de parlants, que sovint oculten el propi coneixement lingüístic i la poca coherència entre dades quantitatives estadísticament adequades o els mecanismes que esbiaixen les entrevistes.

Aquest article és fruit de la recerca duta a terme en el marc del projecte conjunt REDICE08, PID08, PID09 'Com motivar, com adequar l"avaluació continuada i com mesurar el treball a les assignatures de Matemàtiques' durant els cursos 2008 2009 i 2009-2010. El projecte aborda temes relacionats amb els resultats de les enquestes sobre l"actuació docent del professorat a l"ensenyament de Matemàtiques de la Universitat de Barcelona (UB), en què l"alumnat posa de manifest, en general, un baixa motivació del professorat i un elevat volum de feina en les assignatures. Com a resultat de l"estudi i de la pràctica docent en les assignatures involucrades en el projecte citat abans, es desprèn que la motivació de l"alumnat s"aconsegueix sumant esforços en diferents direccions: d"una banda, cal una tria adequada i una bona comunicació dels continguts, que fomenti el diàleg amb l"alumnat; d"altra banda, cal que l"avaluació continuada presenti un esglaonament progressiu en la dificultat de les activitats no presencials i una atenció continuada a l"alumnat mentre les duu a terme. Finalment, cal quantificar la dedicació de l"alumnat a les diferents activitats no presencials, ja que serveix de gran ajuda al professorat a l"hora d"adequar-les a la dedicació requerida, i ponderar les diferents activitats d"avaluació acreditativa en la qualificació de forma proporcional a aquesta dedicació. La motivació pren molta força com a element clau que cal tenir en compte en el bon desenvolupament de la docència universitària. L"alumnat motivat respon amb una més gran dedicació, cosa que comporta la integració de l"alumnat en les assignatures, millors resultats acadèmics i una millor motivació del professorat. Aquest cicle de motivació es va realimentant i va produint efectes molt positius tant en el professorat com en l"alumnat. Una consideració final és que el camí per millorar la docència a Matemàtiques és, segurament, llarg. Tot i així, les reflexions i les actuacions fetes per un nombre considerable de professors de diferents disciplines i departaments de la Facultat de Matemàtiques són experiències que segurament serviran en moltes assignatures de Matemàtiques i d"altres ensenyaments.

The correlation between the species composition of pasture communities and soil properties in Plana de Vic has been studied using two multivariate methods, Correspondence Analysis (CA) for the vegetation data and Principal Component Analysis (PCA) for the soil data. To analyse the pastures, we took 144 vegetation relevés (comprising 201 species) that have been classified into 10 phytocoenological communities elsewhere. Most of these communities are almost entirely built up by perennials, ranging from xerophilous, clearly Mediterranean, to mesophilous, related to medium-European pastures, but a few occurring in shallow soils are dominated by therophytes. As for the soil properties, we analysed texture, pH, depth, bulk density, organic matter, C/N ratio and the carbonates content of 25 samples, correspondingto representative relevés of the communities studied.

On the basis of two parallel data sets refering to phenological events in open scrubs and pastures at two sites (Balaguer and Vic), the authors present a comprehensive report of the phenology of these Mediterranean communities. Four main phenophases (vegetative growth, flowering, fruiting and resting) were recorded monthly in 11 communities over 15 months. The results allow comparisons to be drawn between localities and communities, both at community and species levels, and to consider the effects of contemporary climatic data. This yielded useful information on general trends and on the particular responses of each community type to their corresponding constraints.

La recerca que es presenta té com a objectiu enfocar una de les arrels de la manca de rendiment laboral dels treballadors: la formació que han rebut, en particular aquells que han seguit una trajectòria universitària. Per dur-ho a terme s"ha valorat l"encaix entre el marc didàctic i les competències que s"exigeixen als alumnes a l"hora d"incorporar-se al mercat de treball. S"ha partit d"una enquesta a persones acabades de llicenciar de la Facultat d"Economia de la Universitat de Barcelona, a docents d"aquesta mateixa Facultat i a empresaris. A partir dels resultats obtinguts s"ha fet una anàlisi de la situació dels joves treballadors en termes de competències instrumentals, interpersonals i professionals, centrada exclusivament en la percepció dels empresaris. Segons les conclusions, una planificació de la docència més centrada en l"estudiant, des del punt de vista de la seva formació integral, pot contribuir de forma essencial a incrementar la seva futura productivitat laboral.

En este trabajo se presentan los resultados derivados de la interpretacón de 320 estaciones gravimétricas realizadas sobre el diapiro de Cardona con el objetivo de obtener información sobre su geometría tridimensional. Para obtener una distribución tridimensional de la masa salina que explique las anomalías observadas se ha aplicado un método iterativo de ajustes sucesivos basado en un algoritmo de inversión automática. Esta metodología ha mostrado ser muy rápida, fácil de usar y con suficiente poder de resolución para perfilar no sólo la geometría del cuerpo salino, sino también la de estructuras similares. El diapiro salino de Cardona presenta un mínimo gravimétrico relacionado con el anticlinal de Pins-Cardona que se prolonga hacia el SW. El análisis cualitativo de la anomalía residual permite apreciar que el diapiro muestra una cierta vergencia hacia sur con un flanco sureste subvertical y un flanco noroeste con pendientes más suaves.

The age at which school children begin instruction in the foreign language has been brought forward on two main grounds: (1) young children are better language learners than older children, and (2) bilingualism brings cognitive advantages to children. Both statements are critically analysed in this paper. First of all, recent research findings show that the advantage that younger learners show in a naturalistic language learning situation (or through school immersion) disappears in a formal language learning situation with very limited exposure to the target language. Secondly, the positive effects on cognitive development that have been revealed through research correspond to situations of balanced bilingualism, that is, situations in which children have a high command of the two languages. In contrast, children¿s command of the foreign language in our context is very limited and hence far from the situation of balanced bilingualism (or trilingualism) that is said to bring positive cognitive effects.

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.

Objective: To examine whether drawing is useful in the detection of problems of psychosocial adaptation in children and adolescents with type 1 diabetes (T1D) and in improving communication with health professionals. Methods: We performed an exploratory descriptive study in 199 children and adolescents with T1D aged 413 years. The participants were asked to render a drawing on a suggested topic. The variables analyzed were related to the drawing and to clinical and sociodemographic data. Results: Most participants showed evidence of having a well-balanced personality, but there were also signs of affective or psychosocial difficulties. Conclusion: Drawing is a useful technique by which to identify children"s and adolescents" feelings and possible problems in adapting to T1D, as well as to gain information directly from the children themselves. Future studies should delimit the possibilities of this technique in clinical practice in greater detail.

Hasta no hace demasiados años, la naturaleza y la biología eran de los pocos fenómenos que proporcionaban seguridad debido a su estabilidad. En la actualidad estos procesos están cambiando rápidamente y el imaginario social se debe adaptar. Objetivo. El objetivo de este trabajo consiste en conocer la opinión de los jóvenes sobre la reproducción asistida (captar las representaciones ideológicas, valores, y creencias). Diseño y metodología: Se han realizado cinco grupos de discusión de seis jóvenes cada uno. La información generada en la investigación se ha presentado en forma de texto narrativo y posteriormente se ha realizado su análisis siguiendo el esquema propuesto de Miles y Huberman. (1994). Resultados: Se han establecido seis categorías que han emergido de los discursos, y finalmente se han analizado en un mapa de significados. Conclusiones: La tecnología reproductiva puede facilitar cambios en el territorio familiar y sobretodo en el femenino, al promover a partir de su reflexión cambios en las construcciones culturales de las personas. Sería conveniente establecer programas educativos en los que se informara sobre las estadísticas de infertilidad y sus causas, así como las técnicas de reproducción asistida que se pueden utilizar; éxitos, fracasos, y complicaciones, pues existe desconocimiento y confusión en sus futuros usuarios.

Des d'una perspectiva moderna, l'acolliment familiar és un recurs social que implica atorgar la guarda d'un menor a una persona o nucli familiar, amb l'obligació de cuidar-lo, alimentar-lo i educarlo per un temps, amb la finalitat d' integrar-lo en una vida familiar que substitueixi o complementi temporalment la seva natural (Llei 37/1991, Generalitat de Catalunya). L'acolliment familiar s'ha obert i adaptat a les necessitats actuals deis nen/es i joves, unes necessitats com més va més complexes. En aquest sentit, avui en dia parlem de diverses modalitats d'acolliment: amb previsió de retorn; sense previsió de retorn o/i preadoptiu. Cada una d'aquestes modalitats permetra respondre a les diverses situacions deis infants i de les seves famílies. Pero per garantir l'interés del menor i desenvolupar una bona practica de l'acolliment familiar cal tenir ben estructurades les diverses fases que composen un programa d'acolliments familiars.
