Organització del temps de pràctica motriu en la programació i desenvolupament de les sessions d'E.F a l'IES Monsacopa d'Olot

L’educació física és una matèria que presenta diferències estructurals i organitzatives significatives respecte la resta d’àrees. L’anàlisi de la pràctica diària durant les sessions, ens demostra els pocs minuts que els alumnes realment disposen per practicar i poder assolir els objectius marcats. Aquesta recerca, pretén fer veure als professors la importància d’una adequada gestió del temps a l’aula amb l’objectiu d’augmentar el temps de pràctica motriu dels alumnes. Per fer-ho, es durà a terme un procés d’investigació on, primerament es definiran els diferents temps que existeixen en una sessió d’educació física, i després, s’analitzaran i es buscaran possibles relacions entre l’organització d’aquests temps dins la programació del professor i durant la realització de les sessions. Per últim, es presenten una sèrie d’estratègies d’intervenció, que poden ajudar al professorat a augmentar el temps dedicat a la pràctica, temps essencial per a l’aprenentatge.

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.

El impacto de las TIC en la empresa turística : el caso de Cataluña

En aquest article s'aporten proves de l'impacte positiu que té l'aplicació de les tecnologies de la informació i la comunicació (TIC) en l'empresa turística catalana. La transcendència que en els darrers anys ha adquirit el mercat turístic català en el context europeu el converteix en un laboratori d'anàlisi idoni per al sector. Els resultats obtinguts posen de manifest que l'ús d'aquestes tecnologies s'acompanya d'un major grau d'internacionalització de l'empresa, el desenvolupament de canvis organitzatius i la implantació de noves estratègies competitives, cosa que dóna lloc a un model de negoci allunyat de les concepcions tradicionals del sector. A més, l'ús estratègic de les TIC afavoreix l'ús de mà d'obra més qualificada, un servei més personalitzat i una major proximitat a proveïdors i distribuïdors. Tanmateix, és en el procés d'innovació empresarial on l'impacte positiu de les TIC és percep més, atès que el seu ús ha contribuït a superar alguns dels obstacles existents, a interioritzar el procés en el si de l'empresa i a fer més partícips els mateixos treballadors, i això ha donat com a resultat una àmplia diversitat d'innovacions de tota mena (de producte, de procés i organitzatives). La participació en xarxes de cooperació, el fet de tenir treballadors amb un nivell educatiu elevat i l'aplicació intensiva de les TIC han estat elements indispensables en aquest procés innovador. Finalment, gràcies a l'ús de les TIC i el seu impacte en la innovació, però també al canvi organitzatiu dins l'empresa, s'han millorat els registres de productivitat, amb la qual cosa s'afavoreix una major competitivitat en un context canviant i de forta pressió de l'entorn.

Lepromatous leprosy: a review and case report

Leprosy is a contagious and chronic systemic granulomatous disease caused by Mycobacterium leprae (Hansen"s bacillus). It is transmitted from person to person and has a long incubation period (between two and six years). The disease presents polar clinical forms (the"multibacillary" lepromatous leprosy and the"paucibacillary" tuberculoid leprosy), as well as other intermediate forms with hybrid characteristics. Oral manifestations usually appear in lepromatous leprosy and occur in 20-60% of cases. They may take the form of multiple nodules (lepromas) that progress to necrosis and ulceration. The ulcers are slow to heal, and produce atrophic scarring or even tissue destruction. The lesions are usually located on the hard and soft palate, in the uvula, on the underside of the tongue, and on the lips and gums. There may also be destruction of the anterior maxilla and loss of teeth. The diagnosis, based on clinical suspicion, is confirmed through bacteriological and histopathological analyses, as well as by means of the lepromin test (intradermal reaction that is usually negative in lepromatous leprosy form and positive in the tuberculoid form). The differential diagnosis includes systemic lupus erythematosus, sarcoidosis, cutaneous leishmaniasis and other skin diseases, tertiary syphilis, lymphomas, systemic mycosis, traumatic lesions and malignant neoplasias, among other disorders. Treatment is difficult as it must be continued for long periods, requires several drugs with adverse effects and proves very expensive, particularly for less developed countries. The most commonly used drugs are dapsone, rifampicin and clofazimine. Quinolones, such as ofloxacin and pefloxacin, as well as some macrolides, such as clarithromycin and minocyclin, are also effective. The present case report describes a patient with lepromatous leprosy acquired within a contagious family setting during childhood and adolescence

Nucleophile-Catalyzed Additions to Activated Triple Bonds. Protection of Lactams, Imides, and Nucleosides with MocVinyl and Related Groups

Additions of lactams, imides, (S)-4-benzyl-1,3-oxazolidin-2-one, 2-pyridone, pyrimidine-2,4-diones (AZT derivatives), or inosines to the electron-deficient triple bonds of methyl propynoate, tert-butyl propynoate, 3-butyn-2-one, N-propynoylmorpholine, or N-methoxy-N-methylpropynamide in the presence of many potential catalysts were examined. DABCO and, second, DMAP appeared to be the best (highest reaction rates and E/Z ratios), while RuCl3, RuClCp*(PPh3)2, AuCl, AuCl(PPh3), CuI, and Cu2(OTf)2 were incapable of catalyzing such additions. The groups incorporated (for example, the 2-(methoxycarbonyl)ethenyl group that we name MocVinyl) serve as protecting groups for the above-mentioned heterocyclic CONH or CONHCO moieties. Deprotections were accomplished via exchange with good nucleophiles: the 1-dodecanethiolate anion turned out to be the most general and efficient reagent, but in some particular cases other nucleophiles also worked (e.g., MocVinyl-inosines can be cleaved with succinimide anion). Some structural and mechanistic details have been accounted for with the help of DFT and MP2 calculations.

La fantasia il·lustrada : la fantasia lliure en la segona meitat del segle XVIII

La Fantasia Il·lustrada és un treball d’investigació entorn la fantasia lliure, gènere compositiu de la segona meitat del segle XVIII. Aprofundeix, a partir d’un extens buidatge bibliogràfic, en els coneixements sobre aquest gènere oblidat, ubicant-lo en el seu entorn musical i social, i reconeix l’empremta que va deixar en l’estètica d’aquells anys, la qual justifica la seva vàlua i el clam per reivindicar el reconeixement que es mereix. Per tal d’aconseguir aquest fi, aquest treball elabora sobre les diferents realitats estètiques de meitat de segle, sobre l’art de la jardineria, sobre Carl Philipp Emanuel Bach, i sobre la pràctica improvisativa.
