La enseñanza de Inglés mediante ordenador.

El proyecto intenta, a partir de un enfoque comunicativo, unir enseñanza de idiomas y tecnología, la segunda como aplicación coherente de las ventajas del ordenador para este tipo de enseñanza. Pretende además, despertar el interés del alumno por el uso del ordenador y desarrollar en él destrezas operativas y manipulativas respecto de éste como instrumento de trabajo. Otro de los objetivos era mejorar las destrezas comunicativas y secuenciar la adquisición de otras destrezas de lecto-escritura acercando el proceso de adquisición de la L2 al de la L1 (lengua materna). A comienzos del curso 93-94 se comenzó la progresiva integración del CALL dentro del programa de Inglés del curso con una dedicación de una o dos horas semanales de las cinco dedicadas al idioma. Se llevó a cabo en la sala de ordenadores del centro a la que acudían en grupos de 22 personas y 2 alumnos por ordenador. Se aplicó a un total de 200 alumnos de quinto, sexto,séptimo, octavo y primero de BUP que ya conocían la metodología desde su incorporación al centro y a otros grupos especiales de preparación de los exámenes Cambridge. Se seleccionaron 11 temas : People, Inventions and Discoveries, Travelling, Ecology, Animals, Sports, Future, Free Time, Cinema, Music and Nature. Los contenidos seleccionados eran de dos tipos: los que proporcionaban los programas adquiridos, en la mayoría de los casos secuenciados por niveles y por temas, y los que el profesor y los alumnos incorporaban con el editor. Una vez elegido el vocabulario que se consideraba que los alumnos debían trabajar en estos niveles educativos, se procedió a la elaboración de los ejercicios donde se incluían los items seleccionados. Para ello se recogieron 6 actividades tipo, relacionadas con la adquisición de vocabulario y con su evaluación. Estos fueron básicamente: definición, palabras que faltan, ordenar una frase, verdad-mentira, elección múltiple, cloze. Se comprobó que la individualización e interacción de alumnos con el ordenador repercute en la eficacia, y el CALL es especialmente efectivo en el caso de la lecto-escritura, y para la adquisición de vocabulario y la transferencia de vocabulario pasivo a activo. Queda demostrado que el CALL es un medio de enseñanza que debe tener un lugar integrado en el conjunto de recursos didácticos del programa. Se utilizaron los programas: Striptext, Time, Numbers and Prepositions, Reading Exercices, Fast Fingers, Coptone Down, Nought and Crosses, Rank Order, Multitester, Dealing with texts, Comparative and Superlative, First Certificate, Which Word, Anagrams, Alphagrame, Mind Word, Word Order, Vocabulary WordStore.

Els ambients al CEIP Son Basca

Aquest article es va escriure el 2009. Des de llavors, les autores han anat fent cam?? realitzant modificacions de diferents aspectes per tal d'adaptar-se a les necessitats i demandes dels infants. Actualment, no es treballen aquests mateixos ambients ja que s???ha anat perfilant la filosofia de feina com a equip de cicle i com a centre.

Manifestacions musicals a Barcelona a través de la festa: les entrades reials (segles XV-XVIII)

El tema d'aquesta tesi és el factor de la festa en l'articulació de pràctiques musicals a Barcelona en un context que s'estén des del segle XV al XVIII. Concretament, se centra en les anomenades "Entrades Reials", unes celebracions públiques que s'esdevenien en la primera visita del monarca en motiu del seu jurament dels privilegis de la ciutat. L'elecció d'aquest objecte es justifica en primer lloc pel seu potencial per a connectar amb formes de pensament que incideixen en el debat més genèric sobre els processos d'atribució de significacions a la música. Aquestes celebracions esdevenien una important manifestació cultural col·lectiva en les que s'utilitzaven pràctiques musicals comuns a les altres festes més regulars i que conformaven el sistema general festiu: l'acompanyament del seguici per conjunts de trompetes i tabals, les intervencions musicals en el marc de les representacions realitzades al portal de la ciutat i basades en el teatre sacre medieval, les desfilades dels gremis i confraries, que participaven amb les músiques i els balls dels "entremesos" del Corpus, així com els balls privats als palaus o públics als carrers i places que durant les jornades posteriors completava el conjunt de les activitats.

A intersecção Música-Psicanálise

Artigo que interroga o clamoroso silêncio dos principais nomes da História da Psicanálise sobre a Música e estabelece os princípios da Intersecção Música-Psicanálise, assim como o que se pode esperar de uma orientação lacaniana nesta matéria.

Muses

The Muses are goddesses and teachers of divine wisdom evoked in dance, music, and poetry. Late sources suggest that they invented the alphabet (Diod. Sic. 7.74.1) and the arts and sciences (Anth. Lat. 1.1.88; 1.2.664).

Modern lovers

Modern Lovers was a survey show of contemporary art practices in dialogue with modernism, bringing together established and emerging artists based in London and international artists from Berlin, Jerusalem and Zagreb. The show features video, film, installation, sculpture, music and performance work that addresses the legacy of the avant garde and the survival of its aesthetics within contemporary culture. In 1976, as punk rock was busy smashing the cultural rubble left behind by the second world war and rejecting the consumer society that had emerged from the ruins, one band bravely announced that it wanted no part in this destruction. Jonathan Richman's Modern Lovers sang about how they still loved the old world. Neither parents nor girlfriends could understand, but the decaying inner city with its false promises of progress still held a fascination for Richman, who claimed he wanted to keep his place in this arcane landscape. Punk's assault on culture was the logical conclusion of modernism's linear narrative of art as a force of innovation that must reject preceding artistic movements to establish new ones. Echoing the negations of Dada, it set out to put an end to this narrative, an end to culture. It is partly because of this inherently destructive and totalising side of Modernism that it has come under harsh critique in the post modern era. Nevertheless, we are still caught up in the same dialectic of progress, revolution and destruction. Post modernism has failed to unseat our desire for the revolutionary moment, even as it has been co-opted to the degree of meaninglessness by the discourses of marketing and Capitalism. But, like Jonathan Richman, the artists in the exhibition "Modern Lovers" keep returning to modernism for something else. Instead of taking it at its word when it proffers revolution, they turn to it in search of reform. Still loving the old world and desiring a dialogue with the past, perhaps as an antidote to the eternal present of Capitalism, they are willing to engage with its aesthetics and ideas on equal ground. Leaving behind the ironic deconstructions of post modernism, they find perspectives worth salvaging and juxtapose them with contemporary visual productions. Trading in the grand narratives of modernity for a more personal approach, they don't seek the purity of form that drove the avant garde movements that inspire them but rather revel in adulteration, dilution and contamination of the past by the present". A live performance by sala-manca was sponsored by the British Council and took place May 26th, 19:00. MODERN LOVERS was accompanied by a catalogue (14.80 cm x 14.80 cm) including essays by Avi Pitchon, the sala-manca group and the curators. A discussion panel about the exhibition themes, as well as the catalogue launch,took place at Goldsmiths College's cinema on the 27th of May at 14:00, chaired by Dr. Suhail Malik (Senior Lecturer & Course Leader Postgraduate Fine Art Critical Studies at Goldsmiths College) and with the participation of Tom Morton (curator, Cubitt Gallery, and regular contributor to Frieze magazine), sala-manca (artist group), Dr. Amanda Beech (artist, curator and senior lecturer at the Wimbledon School of Art), Matthew Poole (course director of MA Gallery Studies, dept. of Art History and Theory at the University of Essex).

A kinetic model for the formation of acrylamide during the finish-frying of commercial French fries

Acrylamide is formed from reducing sugars and asparagine during the preparation of French fries. The commercial preparation of French fries is a multi-stage process involving the preparation of frozen, par-fried potato strips for distribution to catering outlets where they are finish fried. The initial blanching, treatment in glucose solution and par-frying steps are crucial since they determine the levels of precursors present at the beginning of the finish frying process. In order to minimize the quantities of acrylamide in cooked fries, it is important to understand the impact of each stage on the formation of acrylamide. Acrylamide, amino acids, sugars, moisture, fat and color were monitored at time intervals during the frying of potato strips which had been dipped in varying concentrations of glucose and fructose during a typical pretreatment. A mathematical model of the finish-frying was developed based on the fundamental chemical reaction pathways, incorporating moisture and temperature gradients in the fries. This showed the contribution of both glucose and fructose to the generation of acrylamide, and accurately predicted the acrylamide content of the final fries.

Experimenting on contextualism

In this article we refine the design of context shifting experiments, which play a central role in contextualist debates, and we subject a large number of scenarios involving different types of expressions of interest to contextualists, including ‘know’ and color adjectives like ‘green’, to experimental investigation. Our experiment (i) reveals an effect of changing contexts on the evaluation of uses of the sentences that we examine, thereby overturning the absence of results reported in previous experimental studies (so-called null results), (ii) uncovers evidence for a ‘truth bias' in favor of positive over negative sentences, and (iii) reveals previously unnoticed distinctions between the strength of the contextual effects displayed by scenarios involving knowledge ascriptions and scenarios concerning color and other miscellaneous scenarios.

Want to block earworms from conscious awareness?B(u)y gum!

Three experiments examine the role of articulatory motor planning in experiencing an involuntary musical recollection (an “earworm”). Experiment 1 shows that interfering with articulatory motor programming by chewing gum reduces both the number of voluntary and the number of involuntary—unwanted—musical thoughts. This is consistent with other findings that chewing gum interferes with voluntary processes such as recollections from verbal memory, the interpretation of ambiguous auditory images, and the scanning of familiar melodies, but is not predicted by theories of thought suppression, which assume that suppression is made more difficult by concurrent tasks or cognitive loads. Experiment 2 shows that chewing the gum affects the experience of “hearing” the music and cannot be ascribed to a general effect on thinking about a tune only in abstract terms. Experiment 3 confirms that the reduction of musical recollections by chewing gum is not the consequence of a general attentional or dual-task demand. The data support a link between articulatory motor programming and the appearance in consciousness of both voluntary and unwanted musical recollections.

Caesalpinia decapetala extracts as inhibitors of lipid oxidation in beef patties

In this study we investigated the effects of Caesalpinia decapetala (CD) extracts on lipid oxidation in ground beef patties. Plant extracts and butylated hydroxytoluene (BHT) were individually added to patties at both 0.1% and 0.5% (w/w) concentrations. We assessed the antioxidant efficacy of CD by the ferric reducing antioxidant power (FRAP) assay and evaluated their potential as natural antioxidants for meat preservation by thiobarbituric acid reactive substance (TBARS) values, hexanal content, fatty acid composition and color parameters. These were tested periodically during 11 days of refrigerated storage. TBARS levels were significantly lower (p ≤ 0.05) in the samples containing plant extracts or BHT than in the non-treated control. In addition, the beef patties formulated with the selected plant extracts showed significantly (p ≤ 0.05) better color stability than those without antioxidants. These results indicate that edible plant extracts are promising sources of natural antioxidants and can potentially be used as functional preservatives in meat products.

Progress report from the strategic sanctuary for the destruction of free will

Progress Report from the Strategic Sanctuary for the Destruction of Free Will presents a new work combining film, music and installation that juxtaposes the setting of the institution with the aesthetics of psychedelia.Progress Report from the Strategic Sanctuary for the Destruction of Free Will is an installation, film and sound work that takes over the gallery. Using plain white card, it distorts the structure of the gallery’s architecture, producing a paranoid shrunken space. Inside this space, performers in cardboard costumes re-enact abstracted, broken gestures drawn from video documentation of acid trips, psychedelic dancing, rehab sessions and radical psychotherapy workshops. Progress Report from the Strategic Sanctuary for the Destruction of Free Will has been formed through Pil and Galia Kollectiv’s research into the anti-psychiatry movement, their interests in counter cultural movements and their studies around biopolitics and the proliferation of societal medication. In 1958, having had a life changing experience with LSD, former alcoholic Charles Dederich founded Synanon, a drug rehabilitation program based on residential care and an aggressive form of group therapy called ‘The Game’. The organisation gradually evolved into a controversial alternative community, described in a critical pamphlet as creating Strategic Sanctuaries for the Destruction of Free Will, “a subversive program for mixing delinquents and lefties”. In 1984, anti-psychiatrist R. D. Laing described tranquillizers as chemical straight jackets. With our growing understanding of the plasticity of the brain and the potential to shape it, the tension between liberation and control in the struggle over the mind continues to define our relationship to labour, culture and production. Interrogating these ideas, the exhibition poses the question of whether a collective body can overcome the solipsism of the incommunicable experience of the individual mind.

Two new species of Cnemidophorus (Squamata: Teiidae) of the C. ocellifer group, from Bahia, Brazil

Two new species of Cnemidophorus are described from the right bank of the Sao Francisco river, in the northwestern part of state of Bahia, Brazil. Both species are assigned to the Cnemidophorus ocellifer group and are distinguished from all other congeners on the basis of lepidosis and color pattern. One of them, Cnemidophorus cyanurus, shares with the species of the subgroup of C. littoralis (C. abaetensis, C. littoralis and C. venetacaudus), a bluish green tail, spurs on the heels of males, 6-7 supraciliaries, a high number of femoral pores (27-45), a row of enlarged scales in the dorsal part of the humerus, and 8 to 10 rows of ventral scales. The second species, Cnemidophorus nigrigula, shares with the C. ocellifer subgroup (composed of C. ocellifer, C. mumbuca, C. jalapensis and C. confusionibus) a low number of femoral pores (1421), enlarged scales in the temporal region posterior to the third subocular, 5 supraciliaries, 6 to 8 rows of ventral scales, and a brown tail color. It is also characterized by males being conspicuously larger than females and by females retaining the juvenile color pattern, which is lost in adult males. The latter characteristic has not been reported in any species of the C. ocellifer group before now. The two new species occur sympatrically at Santo Inacio.

Loxosceles chapadensis (Araneae: Sicariidae): a new recluse spider species of the gaucho group from Brazil

A new species of the medically important recluse spider genus Loxosceles Heinecken & Lowe 1832 is described from the State of Bahia, Brazil. The species occurs between rocks and crevices, as well as in and around man-made structures. The new species belongs to the gaucho group, as evidenced by the spermathecal shape and color pattern. The presence of a long male palpal tibia is unusual in the gaucho group; thus, the inclusion of the new species in this group is discussed.

Selecting salient objects in real scenes: An oscillatory correlation model

Attention is a critical mechanism for visual scene analysis. By means of attention, it is possible to break down the analysis of a complex scene to the analysis of its parts through a selection process. Empirical studies demonstrate that attentional selection is conducted on visual objects as a whole. We present a neurocomputational model of object-based selection in the framework of oscillatory correlation. By segmenting an input scene and integrating the segments with their conspicuity obtained from a saliency map, the model selects salient objects rather than salient locations. The proposed system is composed of three modules: a saliency map providing saliency values of image locations, image segmentation for breaking the input scene into a set of objects, and object selection which allows one of the objects of the scene to be selected at a time. This object selection system has been applied to real gray-level and color images and the simulation results show the effectiveness of the system. (C) 2010 Elsevier Ltd. All rights reserved.
