El tema de la mort continua essent el tema més tabú en la nostra societat . Ni a les famílies, ni als alumnes, ni a l’escola en parlem. I quan esdevé una mort, a part de totes les emocions que ens afloren, no sabem ni com viure-la ni com ajudar a viure-la per elaborar un procés de dol correcte. Aquí trobareu una exposició teòrica del concepte de la mort i del dol que té la societat actual, així com un breu repàs al llarg de la història i les cultures. S’hi exposa com perceben la mort els infants i les característiques dels processos de dol que elaboren en les diferents etapes, fent especial esment a l’edat de 5 a 8 anys, etapa del CI de l’Educació Primària a l’escola. També hi podeu trobar l’eix central del treball, una proposta d’activitats per a treballar i reflexionar sobre la mort a l’aula de CI, que pretén ajudar a preparar als infants per afrontar les pèrdues i trencar el concepte de mort com a tabú

Aquest Treball Final de Grau aporta els resultats d’un estudi sobre els efectes i condicionats que suposa pel rendiment acadèmic dels alumnes de cicle superior de primària el divorci o la separació dels seus progenitors. Ens trobem davant l’augment del nombre de trencaments familiars, que ha esdevingut un fenomen clarament observable en la societat, es tracta d’un fenomen complex, en el qual entren en joc nombroses variables. I el trencament també suposa conseqüències socials, en primer lloc, pels fills/es. En una primera part ens endinsem en les aportacions i teories que han defensat diversos experts al llarg del temps sobre aquest fet. En una segona part es presenten les conclusions i els acords extrets de diverses entrevistes amb mestres d’una escola local en relació a la possible vinculació entre trencament familiar i rendiment acadèmic. I, per últim, s’acaben comparat les visions dels autors teòrics amb les aportacions i visions dels educadors professionals; per arribar a les principals conclusions que, no es pot generalitzar els efectes negatius de la ruptura, cal veure també les possibilitats positives del moment i, per últim, destacar que la manera amb la qual la família s'afronta a la ruptura té una importància crucial a l'hora de determinar l'impacte d'aquesta la ruptura en els fills.

Els coneixements previs són el punt de partida per a construir un coneixement de forma significativa. Cal analitzar-los i tenir consciència dels models mentals dels infants per a poder fer un canvi conceptual que ens porti del coneixement intuïtiu al coneixement científic. És per això que aquesta investigació fa un anàlisi d’aquests coneixements en el contingut d’astronomia. El mètode de recollir les dades és fa a través d’una entrevista a 10 nens i nenes de 6 a 7 anys d’una escola pública de Sabadell. Les dades interpretades es representen en taules i gràfics. Els resultats ens demostren que l’experiència pròpia fa que els infants construeixin els seus propis models mentals.

In this paper we will find a continuous of periodic orbits passing near infinity for a class of polynomial vector fields in R3. We consider polynomial vector fields that are invariant under a symmetry with respect to a plane and that possess a “generalized heteroclinic loop” formed by two singular points e+ and e− at infinity and their invariant manifolds � and . � is an invariant manifold of dimension 1 formed by an orbit going from e− to e+, � is contained in R3 and is transversal to . is an invariant manifold of dimension 2 at infinity. In fact, is the 2–dimensional sphere at infinity in the Poincar´e compactification minus the singular points e+ and e−. The main tool for proving the existence of such periodic orbits is the construction of a Poincar´e map along the generalized heteroclinic loop together with the symmetry with respect to .

In this paper we consider vector fields in R3 that are invariant under a suitable symmetry and that posses a “generalized heteroclinic loop” L formed by two singular points (e+ and e −) and their invariant manifolds: one of dimension 2 (a sphere minus the points e+ and e −) and one of dimension 1 (the open diameter of the sphere having endpoints e+ and e −). In particular, we analyze the dynamics of the vector field near the heteroclinic loop L by means of a convenient Poincar´e map, and we prove the existence of infinitely many symmetric periodic orbits near L. We also study two families of vector fields satisfying this dynamics. The first one is a class of quadratic polynomial vector fields in R3, and the second one is the charged rhomboidal four body problem.

La paraula desigualtat en salut és un terme amb molt ressò els últims anys, i un tema d’actualitat que ha desembocat en el desenvolupament d’estratègies de salut pública en diversos països. La desigualtat en salut té el seu origen en les desigualtats polítiques, econòmiques i socials que existeixen en la societat. Fa referència a les diferents oportunitats i recursos relacionats amb la salut que tenen les persones en relació a la classe social, gènere, ètnia o territori. Per tant, el concepte de desigualtat en salut té una dimensió ètica i moral. Es refereix a diferències en salut innecessàries, inevitable, injustes i intolerables. Assolir la equitat en salut equivaldria a donar oportunitat a tots els individus i a tots els col·lectius de desenvolupar la seva salut. En la majoria de països del món, incloent Espanya, s’ha evidenciat l’existència de desigualtats en matèria de salut pel que fa a l’accés als serveis de salut dels col·lectius més desafavorits.

Anàlisi de les interaccions, a nivell neuronal, que tenen lloc durant el desenvolupament embrionari entre el receptor Unc5B (receptor present a la membrana) i les proteïnes Netrin-1 i FLRT3 (fibronectin and leucine-rich transmembrane proteins). La interacció entre aquest receptor i Netrin-1 ha estat profundament estudiada fins al moment, de manera que es coneix que aquesta promou una repulsió en la guia d’axons durant el desenvolupament embrionari. A més, la interacció està implicada en la senyalització per a diferents processos com l’angiogènesi i la supervivència cel·lular. Per altra banda, la interacció entre neurones Unc5B positives i FLRT3, promou un retard en la migració de les neurones. Diversos estudis demostren que aquest retard en la migració està relacionat amb certes patologies mentals.

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.

Al llarg de l’article hem presentat quina és la situació actual de la intervenció dels professionals a Primària, des del punt de vista de la diversitat cultural, la diversitat funcional, la diversitat en els processos d’aprenentatge, la relació família-escola, la inexistència d’assessorament professional en molts centres, la realitat dels docents en relació a la seva activitat i la metodologia a les aules. Aquests set plantejaments ens han permès elaborar unes propostes de futur centrades en la intervenció, per part del psicopedagog, en la prevenció inespecífi ca, la intervenció en l’avaluació a Primària, la intervenció en la diversitat funcional i la intervenció en la relació entre la família i l’escola…, amb la fi nalitat de mostrar que els canvis són possibles.

Conduziu-se um experimento no período de junho 1998 a dezembro de 2000 na Escola de Agronomia da Universidade Federal da Bahia, em Cruz das Almas, em um Latossolo Amarelo álico coeso para avaliar o impacto do manejo de práticas melhoradoras sobre as propriedades físicas desses solos e a produtividade do mamoeiro. Os tratamentos foram: 1- capina em área total; 2- grade nas entrelinhas e herbicida nas linhas de plantio; 3- capina em área total + subsolagem; 4- subsolagem + feijão-de-porco (Canavalia ensiformis) nas ruas da cultura; 5- Subsolagem + crotalária (Crotalaria juncea) nas ruas da cultura; 6- subsolagem + caupi (Vigna uguiculata) nas ruas da cultura; 7- subsolagem + calagem + gesso agrícola e feijão-de-porco nas ruas da cultura; 8- subsolagem + vegetação nativa nas ruas da cultura, roçada quando necessária. O delineamento experimental foi em blocos casualizados, com três repetições. Cada parcela foi composta por 36 plantas das quais 16 úteis, em espaçamento de 3 x 2 m. A subsolagem foi realizada de forma cruzada antes do plantio nos tratamentos correspondentes. As leguminosas foram plantadas em maio/junho e roçadas em setembro/outubro. O controle do mato nas linhas foi mecânico (T1 e T3) e químico com glifosato na dose de 1% v/v nos demais. Os tratamentos manejados nas entrelinhas da cultura do mamão com leguminosas proporcionaram as maiores alterações nas propriedades físicas de um Latossolo Amarelo álico coeso. Os tratamentos manejados com leguminosas e vegetação espontânea foram os que mais se evidenciaram em produtividade, expressada pelo peso total de frutos (PTF), em toneladas por hectare, e em número total de frutos por hectare NTF).

“Trencant espais fixes: Programa de prevenció contra l’(homo/trans)fòbia a l’escola” és un programa finançat per l’Ajuntament de Barcelona que pren per objectiu prevenir i suprimir l’opressió que reben gais, lesbianes, transsexuals i bisexuals (LGTB) dins del centre educatiu, així com també d’aquells nens i nenes que transgredeixin les normes socials hegemòniques de gènere (establertes dins d’un sistema catalogat com a sexista, patriarcal i heteronormatiu), a través de la formació i apoderament dels docents dels centres educatius públics i concertats dels diferents districtes de Barcelona –fent ús de la prevenció primària, secundària i terciària-. Es pretén fer incís a l’educació de la diversitat afectivo-sexual, a les manifestacions sexistes, al sistema sexe-gènere-desig, als estereotips i prejudicis establerts en la societat i a les diverses dinàmiques de violència, desigualtat i relacions de poder, a fi de sensibilitzar, conscienciar i proporcionar eines als docents per prevenir i poder fer front a les diferents manifestacions discriminatòries a raó d’orientació sexual o identitat de gènere. S’utilitza una metodologia dinàmica i participativa, estructurada en tres sessions de 2,5h en cadascun dels centres educatius inscrits en el programa (a demanda del centre), el qual pren com a principis rectors la perspectiva integral del gènere, la intervenció preventiva, la transversalitat educativa, el procés participatiu i, finalment, l’interseccionalitat de factors identitaris d’una persona. Es pren consideració al Codi Ètic i Deontològic de la professió de Treball Social, ja que el present programa es caracteritza pel seu caràcter sensible i influent en la vida de les persones. Aquets fet suposa certes limitacions pels dinamitzadors dels tallers/sessions, ja sigui per la pròpia sensibilitat o per la manca de participació o de cohesió del grup destinatari.
