Bringing Funds of Family Knowledge to school. The Living Morocco Project (“برغملا شيعلا”)

The purpose of the study, grounded in sociocultural theory, is to describe the funds of knowledge of a Moroccan family living in Catalonia (Spain) in order to document how teachers can use these funds of knowledge to make direct links between students' lives and classroom teaching. The funds of knowledge approach is based on a simple premise: regardless of any socio-economical and sociocultural "deficit" that people may or may not have all families accumulate bodies of beliefs, ideas, skills and abilities based on their experiences (in areas such as their occupation or their religion). The challenge consists in connecting these bodies of educational resources with teaching practice in order to connect the curriculum with students' lives. In doing so, qualitative research can be carried out using several techniques such as self portraits, self-definition tasks, assessment of family artefacts, documenting routines through photographs, or the analysis of a person's significant circle. The results in terms of teaching practices illustrate the variety of ways teachers can make connections between home and school in ways that assist learners in their academic development. In this article, we propose using the term funds of identity to complement the concept of funds of knowledge

The induced 2-tuple linguistic generalized OWA operator and its application in linguistic decision making

[spa] Se presenta el operador de media ponderada ordenada generalizada lingüística de 2 tuplas inducida (2-TILGOWA). Es un nuevo operador de agregación que extiende los anteriores modelos a través de utilizar medias generalizadas, variables de ordenación inducidas e información lingüística representada mediante el modelo de las 2 tuplas lingüísticas. Su principal ventaja se encuentra en la posibilidad de incluir a un gran número de operadores de agregación lingüísticos como casos particulares. Por eso, el análisis puede ser visto desde diferentes perspectivas de forma que se obtiene una visión más completa del problema considerado y seleccionar la alternativa que parece estar en mayor concordancia con nuestros intereses o creencias. A continuación se desarrolla una generalización mayor a través de utilizar medias cuasi-aritméticas, obteniéndose el operador Quasi-2-TILOWA. El trabajo finaliza analizando la aplicabilidad del nuevo modelo en un problema de toma de decisiones sobre gestión de la producción.

Leaving the cave in search of life (A Platonic reading of R. Sirera's La caverna (The Cave)

The aim of this article is to show how a contemporary playwright thinks once more of the Platonic image of the cave in order to reflect on the necessary existential journey of men and women as in the case of a Bildungsroman. Sooner or later men and women must abandon the protection that any sort of cavern such as home, the family garden or family itself can offer. In spite of writing from a by no means idealistic or metaphysical point of view, thanks to R. Sirera and to the very applicability of Platonic images, Plato becomes once again a classical reference which is both useful and even unavoidable if one bears in mind the Platonic origin of all the literary caverns.

En torno a los efectos de la edad en el aprendizaje escolar de una lengua extrangera

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.

Heterogeneity, selection and labor market disparities

We study the incentives to acquire skill in a model where heterogeneous firmsand workers interact in a labor market characterized by matching frictions and costlyscreening. When effort in acquiring skill raises both the mean and the variance of theresulting ability distribution, multiple equilibria may arise. In the high-effort equilibrium, heterogeneity in ability is sufficiently large to induce firms to select the bestworkers, thereby confirming the belief that effort is important for finding good jobs.In the low-effort equilibrium, ability is not sufficiently dispersed to justify screening,thereby confirming the belief that effort is not so important. The model has implications for wage inequality, the distribution of firm characteristics, sorting patternsbetween firms and workers, and unemployment rates that can help explaining observedcross-country variation in socio-economic and labor market outcomes.

De la bellesa ornamental a la bellesa comercial : De les relacions entre art i publicitat en l'obra cartellista d'Alphonse Mucha

En aquest treball s'investiga, a través de l'obra d'Alphonse Mucha com autor paradigmàtic de l'Art Nouveau en el context geogràfic del París de finals del segle XIX i principis del XX, la possible influència de la publicitat en la difusió i consolidació de les creences i valors dels grups socials més ben posicionats, i molt especialment en el cas de la dona, ja que l'obra de Mucha està centrada bàsicament en la figura femenina. Així mateix, també es busca esbrinar la intervenció d'aquests grups en la creació d'un camp artístic que alhora faria possible la contemplació estètica de l'anunci comercial, i que esdevindria un element més d'aquesta moderna cultura, capitalista i urbana, de grans transformacions i avenços tecnològics, i que des d'una òptica crítica com la de l'Escola de Frankfurt, estaria 'cosificant' l'individu en nom de la ciència i el progrés, des del moment en què aquest quedaria condemnat al consum il·limitat per tal de satisfer un desig insaciable: l'afany d'emulació de la classe ociosa, o dit d'altra manera, d'aquella que el domina.

Gènere i sexoafectivitat segons els adolescents dels usuaris dels centres oberts de la ciutat de Girona

L’objectiu d’aquest treball és conèixer la percepció que tenen els adolescents usuaris dels centres oberts de la ciutat de Girona sobre la sexualitat, l’afectivitat, quins rols de gènere se’n deriven i quines creences els sustenten. El disseny del treball ha estat qualitatiu, observacional, grups de discussió. Pel que fa als subjectes i al mètode, la població seleccionada ha estat de 33 adolescents i joves d’edats compreses entre els 12 i els 22 anys, usuaris de quatre centres oberts de Girona: el centre obert de Taialà, el Centre Obert de Font de la Pólvora (Onyar), el Centre Obert de Santa Eugènia i el Centre Obert del Barri Vell. Es van dur a terme grups de discussió d’una hora de duració sense descans amb d’entre 6 i 8 persones a partir d’un guió format per diversos mites i frases en relació a diversos temes (El festeig, la virginitat, la curiositat pel cos i per la sexualitat, els anticonceptius i les principals fonts d’informació) sobre les que havien de dir si estaven d’acord o no i qui creien que les deia (si un noi o una noia). Sobre els resultats del treball cal dir que s’ha observat la persistència d’algunes creences del model del amor romàntic en relació al rols de gènere com la definició de la dona vinculada a papers de cura i prevenció, una dona que té accés a la sexualitat però segueix estan catalogada per la vivència d’aquesta essent una persona “respectable” o una “puta”, que pren un rol més actiu en la iniciativa però no el l’assertivitat en les relacions; i un home, més impulsiu i sexual. En relació als comportaments sexuals destacar l’embaràs no desitjat com la principal preocupació de les relacions i el desconeixement/confusió entre els mètodes anticonceptius i de barrera disponibles a la xarxa de salut. Apareix la pornografia com a model emergent de relacions sexuals i models de relació entre homes i dones, en contraposició a altres fonts de informació i consulta tradicionals com els amics que segueixen essent la més significativa, la família, els serveis socials i educatius, i Internet. Com a conclusió cal dir que queda palesa la necessitat de incorporar una perspectiva de gènere en la formació curricular dels joves i el fet de seguir replantejant les millors estratègies d’intervenció per una concepció integradora de la sexualitat

Propuesta de programa de prevención de trastornos de la conducta alimentaria y la obesidad dirigido a profesores de educación física de secundaria

En la actual concepción bio-psico-social, los Trastornos del Comportamiento Alimentario (TCA) y la obesidad están plurideterminados por factores biológicos, psicológicos y socioculturales que actúan como elementos perpetuantes en el tiempo. Se pueden modificar actitudes contraproducentes con un programa de prevención multidisciplinar y disminuir de modo significativo la población con riesgo de obesidad y de padecer un TCA. Para ello, es necesario desarrollar dichos programas de prevención, previos a la atención primaria, y la estrategia para lograrlo es la intervención ante factores de riesgo, integrada en un conjunto de actividades de educación para la salud más global. Esta propuesta educativa pretende brindar a los profesores de Educación Física una revisión bibliográfica sobre la dimensión que desde la cultura occidental se tiene de los Trastornos del Comportamiento Alimentario (TCA) y la obesidad, al tiempo que promueve la reflexión sobre las posibilidades de intervención que ofrece la Educación Física desde el ámbito educativo en cuanto a la prevención de la obesidad, de los TCA, y de las conductas de riesgo. La presente propuesta de proyecto de prevención quiere destacar la función que cumplen docentes, tutores y tutoras, como acompañantes de los estudiantes, su posición privilegiada para conocerlos de cerca y estar así atentos a sus vivencias y la posibilidad de identificar oportunamente conductas no saludables en estudiantes que necesiten ciertas pautas para mejorar su estilo de vida, modificar sus habitos, o ser derivados para una atención especializada. Por ese motivo, en esta propuesta educativa se invita a los docentes y tutores a revisar sus convicciones personales y cuestionar la manera de pensar sobre la belleza física y el cuidado corporal. Esta reflexión junto a las pautas metodológicas permitirá abordar el tema de los TCA y la obesidad con tacto, respeto y la atención necesaria frente a los sentimientos de los y las estudiantes que se encuentran en un periodo de cambios importantes y con interrogantes en torno a su identidad e imagen corporal

Planning under partial observability by classical replanning: theory and experiments

Planning with partial observability can be formulated as a non-deterministic search problem in belief space. The problem is harder than classical planning as keeping track of beliefs is harder than keeping track of states, and searching for action policies is harder than searching for action sequences. In this work, we develop a framework for partial observability that avoids these limitations and leads to a planner that scales up to larger problems. For this, the class of problems is restricted to those in which 1) the non-unary clauses representing the uncertainty about the initial situation are nvariant, and 2) variables that are hidden in the initial situation do not appear in the body of conditional effects, which are all assumed to be deterministic. We show that such problems can be translated in linear time into equivalent fully observable non-deterministic planning problems, and that an slight extension of this translation renders the problem solvable by means of classical planners. The whole approach is sound and complete provided that in addition, the state-space is connected. Experiments are also reported.

El rol del paciente experto en el tratamiento de las adicciones: una propuesta para paliar las altas tasas de abandono prematuro en comunidades terapéuticas

El objetivo de este estudio recae en cómo y de qué forma el ex adicto a sustancias alteradoras del ánimo (E-ASAA), cursando por el estadio de mantenimiento, puede ejercer el rol de asesor y promotor de salud, como “Paciente Experto”, conjuntamente con los profesionales especializados en drogodependencias. Paralelamente este “cómo y de qué forma” viene a dar respuesta a una necesidad existente en las Comunidades Terapéuticas, a saber, reducir las Altas Voluntarias (AV) de los residentes recién incorporados y tras su Alta Terapéutica (AT). Sin embargo, se requiere de una investigación de tipo cualitativo para determinar los factores desencadenantes que inducen a esta prevalencia de AV y recaídas post-AT. Los resultados extraídos de la investigación a informantes clave muestran como existe un deficitario asesoramiento pre-entrada y acompañamiento post-AT. El E-ASAA, debidamente formado, podría dar respuesta a estas demandas asistenciales, mejorando así la completa reinserción de los usuarios de CCTT. La Propuesta del Proyecto “Mi amigo de Comunidad” integra este conocimiento aportando soluciones.

Com influencia la pràctica Dalcroze en l'estimulacio de les diferents capacitats dels infants

Aquest treball consta d’un procés d’investigació en el qual hi podem trobar la corroboració de la pregunta inicial sobre com influencia la pràctica Dalcroze en l’estimulació de les diferents capacitats dels infants. Aquest mètode consisteix en estimular la coordinació i la maduresa personal de l’infant i està basat en el moviment i la percepció del ritme. Basant-me en el què diuen alguns autors i pedagogs s’han comprovat les hipòtesis a partir d’una investigació. Per poder investigar aquest fet s’han realitzat una sèrie d’observacions de diferents sessions de música amb infants de tres a set anys de dues escoles diferents. En una de les escoles, en la qual s’ha estat investigant, els alumnes fan música a partir del mètode Dalcroze i a l’altre escola no. A partir de les observacions de totes les sessions de música s’ha analitzat i comparat les dues maneres de treballar la música i les capacitats que es poden desenvolupar treballant la música d’una manera vivencial i dinàmica. Per fer la part pràctica s’ha utilitzant una metodologia qualitativa la qual investiga si a partir de la rítmica Dalcroze es poden estimular les diferents capacitats dels infants. Les dades han estat recollides en una graella d’observació on hi ha transcrita cada una de les sessions de música de les dues escoles, també han estat recollides a partir de les gravacions de totes les sessions i dues entrevistes realitzades a les professores de música. A partir d’aquí ha començat el procés d’investigació i anàlisi.
