    La propuesta de innovación docente que presentamos se ha experimentado con los estudiantes de la especialidad de Educación Física en Magisterio. La idea globalizadora parte de un elemento físico (el caracol) y de un icono (la espiral), se apoya en un artista andaluz universal, Pablo Ruiz Picasso, y necesita recabar información sonora y visual. Con todo ello, la acción consiste en la elaboración por parte de los estudiantes de pósters que recojan la información y permitan hacer demostraciones prácticas a través del movimiento. Desde los ámbitos transdisciplinar y ecoformativo, ayudaremos a comprender el arte, la música, la expresión corporal, el movimiento y la actividad física. En definitiva, se trata de llegar a la cultura por medio de las materias que conforman el Departamento, en un proceso creativo, interdisciplinar e innovador que abarque también las competencias básicas.The proposal of educational innovation that we display in this contribution has been applied to university students of Physical Education (EF). The global idea departs from a physical element (the snail), an icon (the spiral) and an Andalusian and universal artist, Pablo Ruiz Picasso, to successfully obtain musical and artistic information. The action consists on the elaboration by the students of posters which collect information and allow realize practical demonstrations through movement. “The snail-the spiral” is an image that opens to the multisensory field and aids to understand art, music, corporal expression, movement and physical activity, from transdicisciplinary and ecopedagogical scopes. The aim is to obtain a cultural approach through the subjects which conform the Department, by means of a creative, interdisciplinary and innovative process which also includes the basic competencies

    Las tendencias sociales y culturales del Ecuador son una gran oportunidad para el mercado de florerías ya que los ecuatorianos somos personas cálidas y sensibles y celebramos las festividades son celebradas independientemente de la situación económica. Los consumidores ecuatorianos no consideran a las flores como un regalo común, sino como expresión de sentimientos hacia de una persona hacía otra, las razones para obsequiar un detalle son, por ejemplo, para felicitar a alguien, como es el caso de los cumpleaños; para pedir disculpas, para dar el pésame, o como signo de amor..

    Centrality dependence of photon yield and elliptic flow from gluon fusion and splitting induced by magnetic fields in relativistic heavy-ion collisions

    Full text link
    We compute the photon yield and elliptic flow coefficient in relativistic heavy-ion collisions from gluon fusion and splitting processes induced by a magnetic field for different centralities. The calculation accounts for the intense magnetic field and the high gluon occupation number at early times. The photon production induced by these process represents an excess contribution over calculations without magnetic field effects. We compare this excess to the difference between PHENIX data and recent hydrodynamic calculations for the photon transverse momentum distribution and elliptic flow coefficient v2v_2. The time evolution of the field strength and reaction volume is computed using UrQMD. We show that with reasonable values for the saturation scale, the calculation helps to better describe the experimental results obtained at RHIC energies for the lowest part of the transverse photon momentum at different centralities.Comment: Expanded discussion.

    Editorial: physiological, molecular and genetic perspectives of chilling tolerance in horticultural crops, volume II

    Get PDF
    For crops of tropical and subtropical origin, exposure to low temperatures often causes chilling injury symptoms, which can range from altered appearance (such as surface pitting and discoloration) to severe physiological disorders and impaired metabolism. To cope with suboptimal temperatures in the surrounding environment, crops have evolved complex mechanisms, which entail stress signal perception and transduction, activation of stress-responsive genes, and the synthesis of stressrelated molecules. Plant breeding programs have been instrumental in obtaining chilling-tolerant cultivars in a number of horticultural crops. More recently, the incorporation of molecular and omics-based techniques into conventional breeding procedures has vastly improved breeding strategies by enhancing the efficacy of screening for chilling tolerance-associated traits. Moreover, these new tools will boost knowledge of chilling responses and tolerance mechanisms, and the discovery of related pathways and genes. As a part of the 'Physiological, Molecular and Genetic Perspectives of Chilling Tolerance in Horticultural Crops' series (Lara et al., 2020), this Research Topic was launched with the aim of offering an overview of recent developments in this area. The papers in this collection explored the mechanisms involved in chilling tolerance in a number of plant species, including commercially important fruit crops such as pepper, tomato, banana and peach/nectarine, a medicinal plant (Tetrastigma hemsleyanum) and Arabidopsis. In addition to helping to reveal the mechanisms underlying cold stress tolerance, these findings provide the basis for future breeding programs, and offer clues for the alleviation of stress symptoms.Current work at IL’s lab is funded by grant 2017 SGR 1108 (Generalitat de Catalunya, Catalonia, Spain).

    The Medici effect against the mosaic effect: hybridizations of the research curriculum in music education

    Get PDF
    La presente contribución se concibe como un espacio de reflexión sobre la propia investigación, concretamente sobre la configuración del currículum investigador de profesionales de la Educación Musical que proceden de la carrera musicológica pero que aterrizan en la didáctica teniéndose que adaptar a la investigación educativa por exigencias del sistema con mayor o menor suerte, resistencias o complejos. Tras el estudio y análisis de casos concretos, abogaremos por una línea integrada, interdisciplinar –e innovadora– (efecto Médici) más que por un currículum estratificado y pendular (efecto mosaico), el más frecuente en los investigadores descritos, así como de la necesidad del trabajo en red en lugar del individualismo imperante tradicionalmente en el área.Universidad de Málaga.

    This paper investigates new ways to gen-erate and integrate identities in the class-room using the pedagogical and creativepotential of audiovisual micro-tales. Inlight that the official curriculum with itsgeneral drive silences the individual voic-es of students, we defend the use of theauto-ethnographic method and experi-mentation with both narrative and audio-visual language in favoring interdiscursivi-ty so that students’ voices can be amplified.These conceptual foundations were usedas a guide in an action research projectdesigned as an introductory activity for amusic subject at University. Students fromdifferent backgrounds, interests and pro-files were invited to lay out the narrationof an autobiographical micro-tale withtwo extra literary supports, music and im-age, inquiring in their sounds of life. Thestudy concludes that new understandingswith an interpretative and socio-criticalfocus and a qualitative-methodology arehighly effective in order to give committed answers that empower the intelligenceand capabilities of the students, constructtheir identity and satisfy their interests in acreative and holistic way.La presente investigación tiene como objetivola búsqueda de nuevas formas degenerar e integrar identidades en el aulausando el potencial pedagógico y creativodel microrrelato audiovisionado. Teniendoen cuenta que el currículum oficial ygeneralista suele silenciar las voces individualesde los estudiantes, para amplificarlasdefendemos el uso del métodoautoetnográfico y la experimentacióncon los lenguajes narrativo y audiovisual,favoreciendo la interdiscursividad. Estaspremisas conceptuales guiaron un proyectode investigación-acción diseñado comoactividad introductoria en una asignaturade música universitaria. Los estudiantes,de diferentes procedencias, intereses yperfiles, participaron en la creación y narraciónde un microrrelato autobiográficocon dos soportes extraliterarios, música eimagen, en el que indagaron en su imaginariosonoro. El estudio concluye que estasnuevas aproximaciones desde el focosociocrítico e interpretativo, en combinación con la metodología cualitativa, sonaltamente eficaces a fin de dar respuestascomprometidas que potencian la inteligenciay las capacidades de los estudiantes,favoreciendo la construcción de suidentidad y satisfaciendo sus intereses deuna manera creativa e integral

    Coordinated role of soluble and cell wall bound phenols is a key feature of the metabolic adjustment in a mining woody fleabane (Dittrichia viscosa L.) population under semi-arid conditions

    Environmental contamination by hazardous heavy metals/metalloids (metal(loid)s) is growing worldwide. To restrict the migration of toxic contaminants, the establishment of a self-sustainable plant cover is required. Plant growth in multi-polluted soils is a challenging issue not only by metal(loid) toxicities, but also by the co-occurrence of other stressors. Dittrichia viscosa is a pioneer Mediterranean species able to thrive in metal(loid)-enriched tailings in semi-arid areas. The aim of the present work was to examine the metabolic adjustments involved in the acclimation responses of this plant to conditions prevailing in mine-tailings during Mediterranean spring and summer. For this purpose, fully-expanded leaves, and rhizosphere soil of both mining and non-mining populations of D. viscosa grown spontaneously in south-eastern Spain were sampled in two consecutive years. Quantitative analysis of > 50 biochemical, physiological and edaphic parameters were performed, including nutrient status, metal(loid) contents, leaf redox components, primary and secondary metabolites, salicylic acid levels, and soil physicochemical properties. Results showed that mining plants exhibited high foliar Zn/Pb co-accumulation capacity, without substantially affecting their photosynthetic metabolism or nutritional status even in the driest summer period. The comparison of the antioxidative/oxidative profile between mining and non-mining D. viscosa populations revealed no major seasonal changes in the content of primary antioxidants (ascorbate and GSH), or in the levels of ROS. Multivariate analysis showed that phenylalanine ammonia-lyase (PAL) and peroxidase (PRX) activities and soluble and cell wall-bound phenols were potential biomarkers for discriminating between both populations. During the dry season, a marked enhancement in the activity of both PAL and soluble PRX resulted in both a drop in the accumulation of soluble phenols and an increase of the strong metal chelator caffeic acid in the cell-wall fraction, supporting the view that the plasticity of phenylpropanoid metabolism provide an effective way to counteract the effects of stress combinations.This work was supported by the Ministerio de Ciencia e Innovación [grant number CTM2011-23958]; Ministerio de Ciencia y Tecnología [grant number CGL2006-11569]; and Fundación Séneca [grant number FB/23/FS/02].
