Who is in charge? An L2 Discourse Intonation Study on Four Prosodic Parameters to Exert the Pragmatic Function of Dominance and Control in the Context of L2 Non-specialist Public Speaking

This paper reports the findings from a study of the learning of English intonation by Spanish speakers within the discourse mode of L2 oral presentation. The purpose of this experiment is, firstly, to compare four prosodic parameters before and after an L2 discourse intonation training programme and, secondly, to confirm whether subjects, after the aforementioned L2 discourse intonation training, are able to match the form of these four prosodic parameters to the discourse-pragmatic function of dominance and control. The study designed the instructions and tasks to create the oral and written corpora and Brazil’s Pronunciation for Advanced Learners of English was adapted for the pedagogical aims of the present study. The learners’ pre- and post-tasks were acoustically analysed and a pre / post- questionnaire design was applied to interpret the acoustic analysis. Results indicate most of the subjects acquired a wider choice of the four prosodic parameters partly due to the prosodically-annotated transcripts that were developed throughout the L2 discourse intonation course. Conversely, qualitative and quantitative data reveal most subjects failed to match the forms to their appropriate pragmatic functions to express dominance and control in an L2 oral presentation.

THREE AMERICAN INTERNATIONAL PIANO COMPETITIONS: THE PIANO WORKS THEY COMMISSIONED BETWEEN 1962 AND 2012

Over a period of 50 years—between 1962 and 2012—three preeminent American piano competitions, the Van Cliburn International Piano Competition, the University of Maryland International Piano Competition/William Kapell International Piano Competition and the San Antonio International Piano Competition, commissioned for inclusion on their required performance lists 26 piano works, almost all by American composers. These compositions, works of sufficient artistic depth and technical sophistication to serve as rigorous benchmarks for competition finalists, constitute a unique segment of the contemporary American piano repertoire. Although a limited number of these pieces have found their way into the performance repertoire of concert artists, too many have not been performed since their premières in the final rounds of the competitions for which they were designed. Such should not be the case. Some of the composers in question are innovative titans of 20th-century American music—Samuel Barber, Aaron Copland, Leonard Bernstein, John Cage, John Corigliano, William Schuman, Joan Tower and Ned Rorem, to name just a few—and many of the pieces themselves, as historical touchstones, deserve careful examination. This study includes, in addition to an introductory overview of the three competitions, a survey of all 26 compositions and an analysis of their expressive characteristics, from the point of view of the performing pianist. Numerous musical examples support the analysis. Biographical information about the composers, along with descriptions of their overall musical styles, place these pieces in historical context. Analytical and technical comprehension of this distinctive and rarely performed corner of the modern classical piano world could be of inestimable value to professional pianists, piano pedagogues and music educators alike.

The Danger Theory and its Application to Artificial Immune Systems

Over the last decade, a new idea challenging the classical self-non-self viewpoint has become popular amongst immunologists. It is called the Danger Theory. In this conceptual paper, we look at this theory from the perspective of Artificial Immune System practitioners. An overview of the Danger Theory is presented with particular emphasis on analogies in the Artificial Immune Systems world. A number of potential application areas are then used to provide a framing for a critical assessment of the concept, and its relevance for Artificial Immune Systems.

Aislamiento, producción y evaluación de la patogenicidad de cepas de Hirsutella citriformis Speare para el control de Diaphorina citri Kuwayama, vector de la enfermedad Huanglongbing de los cítricos

La industria citrícola es una de las más importantes industrias con las que cuenta el país y en los últimos años se encuentra amenazada por una plaga que está ocasionando estragos en todas las áreas citrícolas en México, el Huanglongbing o greening la cual es transmitida por el psílido asiático de los cítricos, Diaphorina citri Kuwayama, insecto que ocasiona daño en las plantas al alimentarse de los brotes tiernos y que además es el vector de la bacteria Candidatus Liberibacter asiaticus para la cual no hay cura y por lo que es necesario controlar al insecto que la transmite. Por lo que el presente trabajo consistió en aislar hongos de D. citri micosados, identificarlos en base a sus características morfométricas y usando técnicas moleculares, cultivarlos en diferentes medios de cultivo comerciales de agar para seleccionar aquel en el cual crecen y conidian mejor, se determinó también el tipo de exudados producidos por Hirsutella citriformis en los medios de agar, se cultivaron en dos diferentes medios de cultivo líquido y un sustrato vegetal para obtener mayor cantidad de conidios; también se realizaron bioensayos de laboratorio para determinar la virulencia de las cepas y seleccionar aquellas que pudieran controlar mejor al insecto; se evaluó la patogenicidad que pudieran presentar sobre insectos depredadores de D. citri, y con los resultados obtenidos se seleccionó las cepas que presentaron mayor patogenicidad sobre el insecto vector del HLB para evaluar su actividad sobre el mismo en bioensayo de campo. Se aislaron cinco cepas de insectos micosados provenientes de diferentes regiones citrícolas, se trabajó con ellos además de tres cepas con las cuales ya contaba el INIFAP de General Terán de Nuevo León. Se identificaron morfométrica y molecularmente como Hirsutella citriformis Speare. Los medio comerciales de cultivo en los cuales crecen y presentan mejor conidiación son los medios agar papa dextrosa enriquecidos con extracto de levadura al 0.5 y 1 % en los cuales se obtuvo un crecimiento radial de 3.2 a 3.8 cm para las cepas IB-Hir-2 e INIFAP-Hir-1 respectivamente, a los 34 días de cultivo a 25 ± 1 °C. La conidiación obtenida para las ocho cepas no correspondió al crecimiento radial, pero si concordó en presentarse en los medios enriquecidos con extracto de levadura, los valores variaron desde 1.22 x 10⁶ a 2.79 x 10⁷ para las cepas 2 INIFAP-Hir-2 en agar papa dextrosa e IB-Hir-2 en agar papa dextrosa con extracto de levadura al 1% respectivamente. En medios líquidos la mayor producción de blastosporas obtenida fue 4.3 x 108 blastosporas /ml a los 9 días en el medio de casaminoácidos para la cepa INIFAP-Hir-1, y en caldo papa dextrosa la mayor producción la presentó a los 11 días la cepa IB-Hir-2 (7.7 x 107 blastosporas/ml). La mayor producción de conidios en el sustrato vegetal (arroz) se obtuvo a los 14 días por la cepa INIFAP-Hir-4 (1.97 x 107 conidios/gr). Se analizaron los dos tipos de exudados observados en las cepas usando los métodos de Bradford para proteínas y el del Fenol Sulfúrico para carbohidratos y con estos métodos se determinó que todas las cepas producen ambos tipos de compuestos, además de que las proteínas son los exudados amarillo claro y oscuro, mientras que los carbohidratos corresponden a las gotas cristalinas producidas por las cepas en los diferentes medios de agar. En los diferentes bioensayos de laboratorio las cepas presentaron mayor mortalidad cuando se inoculó por contacto, donde las cepas INIFAP-Hir-1, INIFAP-Hir-2, IB-Hir-1 e IB-Hir-2 mostraron los mayores porcientos de mortalidad media. Al evaluar la patogenicidad de cuatro cepas sobre dos depredadores de D. citri, los resultados fueron similares para tratamientos y testigo y no se presentó micosamiento en los insectos muertos. Bajo condiciones de laboratorio la CL50 y CL90 obtenidas para el aislado INIFAP-Hir-1 fueron, 34 x 105 y 26.7 x 107 respectivamente. En el bioensayo de campo se usaron las cepas INIFAP.Hir-2, INIFAP.Hir-4, IB-Hir-1 e IB-Hir-2 y el mayor porciento de mortalidad obtenida fue 51.049 y el menor 35.7 para las cepas INIFAP-Hir-4 e IB-Hir-1 respectivamente, mientras que el testigo con adherente mostro 6.059 y en el testigo absoluto 4.84 % de mortalidad promedio. Además logramos aislar la cepa que los micosaba de 20 insectos colectados en diferentes puntos de muestreo, identificando en base a sus características morfológicas de crecimiento colonial a tres de las cepas evaluadas y a la cepa nativa de Martínez de la Torre.

A study of lectin activity in buds of Sophora japonica L

Purpose: To identify lectins in Sophora japonica L. (green flower buds, fully formed flower buds, and flower buds as they begin to open) and to study their activity. Methods: Lectin activity was studied using rat hemagglutination method. The protein concentration of the extracts of the agglutinate was determined using Bradford assay. Results: Lectin activity of green flower buds was 1.61 ± 0.11 units/mg protein; fully formed flower buds, 1.81 ± 0.08 units/mg protein; flower buds as they began to open, and 2.05 ± 0.05 units/mg protein. The protein content of extracts from the buds of Sophora japonica L. collected at the stage of green flower buds, at the stage of formed buds, and at the stage of opening flower buds were 3.97 ± 0,04, 3.53 ± 0.07 and 3.13 ± 0.09 mg/ml respectively. Conclusion: This study shows the existence of lectins in Sophora japonica L. buds studied at three different stages of development. The highest lectin activity and protein content are found in the stage of green flower buds.

Study of the allergenic profile of pollen from Platanus hybrida in the city of Evora, Portugal

Background and Aim: Although grasses and olive are the most relevant allergenic species in the Alentejo region, aggravation of allergic symptoms in the early spring, unrelated with those species pollen seasons, has been reported, particularly in urban environment. Plane trees, hence pollen, are highly abundant in the city of Évora, nonetheless allergen pollen profile has not yet been evaluated. The aim of this work was to characterize the allergen profile of pollen from Platanus hybrida, one of the most representative species in Evora showing pollination prior to the main pollen season in Alentejo. Methods: Pollen from Platanus hybrida and Dactylis glomerata was extracted with ammonium bicarbonate buffer, lyophilized and stored at -80ºC until analysis. Protein content was determined by the Bradford method. SDS-PAGE followed by western blot, using allergic patient sera (obtained from the Hospital do Espírito Santo de Évora – HESE), were performed to evaluate the allergen profile of the pollen. Sensitization and cross-reactivity was assessed by solid phase immunoblot. Results: Half of the patient exhibited sensitization to pollen extracts of P. Hybrida. Western blot have shown several immunoreactive bands in the Mr 10-90 kDa range. Immunoreactive bands were also observed in the protein profile according to the pI in the pI range 4.0-6.1. Cross-reactivity of P. hybrida with D. glomerata was found. Although several bands are common to D. glomerata, a band with ~50kDa was observed in P. hybrida but not in D. glometata. Conclusion: These results evidenced allergens found in P. hybrida pollen. Moreover, cross–reactivity between P. hybrida and highly allergenic species such as D. glomerata was found which probably contributes for aggravation of pollinosis in the early spring.

Allergenic profile of Quercus rotundifolia pollen in Alentejo, Portugal

Background and Aim: Grasses and olive are the most relevant allergenic species in the Alentejo region. However, aggravation of allergic symptoms has been reported in the early spring, before grass and olive pollen seasons. Quercus pollen is the most abundant pollen type in the early spring in Alentejo, nonetheless its allergen profile has not yet been evaluated. The aim of this work was to characterize the allergen profile of pollen from Quercus rotundifolia among the most representative species showing pollination in April, prior to the main pollen season in Alentejo. Methods: Pollen from Quercus rotundifolia, Olea europaea and Dactylis glomerata was extracted with ammonium bicarbonate buffer, lyophilized and stored at -80ºC until analysis. Extract from Quercus ilex pollen was kindly offered by Bial. Protein content was determined by the Bradford method. SDS-PAGE followed by western blot, using allergic patient sera (obtained from the Hospital do Espírito Santo de Évora – HESE), were performed to evaluate the allergen profile of the pollen. Sensitization and cross-reactivity was assessed by solid phase immunoblot. Results: Most of the patient evidenced sensitization to pollen extracts of Q. rotundifolia. Protein profile of Q. rotundifolia has shown several bands in the Mr 10-90 kDa, mostly overlapping with Q. ilex. Western blot have shown several immunoreactive bands. Immunoreactive bands were also observed in the protein profile according to the pI in the range 4.0-6.1. Cross-reactivity between Q. rotundifolia with O. europaea and D. glomerata was found. Conclusion: These results evidenced allergens found in Q. rotundifolia pollen. It also shows that protein profile of Q. rotundifolia and Q. ilex are mostly alike suggesting that similarities in allergen profile are expected. Moreover, cross–reactivity between Q. rotundifolia and highly allergenic species such as O. europaea and D. glomerata was found which probably contributes to the aggravation of pollinosis in the early spring. Acknowledgments: This work was supported by FEDER through the “Programa Operacional Fatores de Competitividade – COMPETE” (Strategic projects of ICAAM and ICT 2013-2015). We also aknowledge Bial-Aristegui for supplying pollen and extract samples of Q. ilex.

Perfil em alergénios do pólen de Platanus hybrida

Objetivos: O plátano (Platanus hybrida) é uma árvore frequentemente utilizada em ambiente urbano, com fins ornamentais. Sendo uma árvore de grande porte, produz pólen em grande quantidade. Embora seja responsável por níveis de exposição a pólen elevados no início da primavera, que são coincidentes com queixas da população, o seu potencial alergénico está pouco caracterizado. Este trabalho teve, assim, como objetivo caracterizar o perfil em alergénios do pólen de plátano na cidade de Évora, Alentejo. Métodos: Prepararam-se extratos de amostras de pólen de Platanus hybrida ou Dactylis glomerata utilizando tampão bicarbonato. Os extratos foram liofilizados e conservados a -80ºC. O conteúdo em proteínas foi determinado pelo método de Bradford. O perfil em alergénios foi avaliado por western blot utilizando soros humanos (obtidos mediante consentimento informado de doentes do Hospital do Espírito Santo de Évora – HESE). Resultados: Observou-se teste positivo a P. hybrida em metade dos soros testados. O perfil em proteínas de P. hybrida exibiu diversas bandas imunorreativas com massas moleculares compreendidas entre 10-90 kDa e com pI no intervalo 4,4-7,0. Foram encontradas imunorreativas comuns a Q. rotundifólia e/ou a D. glomerata. Duas bandas identificadas na gama de 50kDa e 60 kDa parecem específicas de P. hybrida. Também se registou reatividade cruzada com D. glomerata. Conclusões: Este trabalho evidencia alguns alergénios encontrados em pólen de P. hybrida. Para além disso mostra ainda a existência de reatividade cruzada com pólen de gramíneas. Estes resultados sugerem que o pólen de plátano, dada a sua grande abundância na cidade de Évora, poderá contribuir para o agravamento a sintomatologia da população que sofre de polinose, em particular no início da primavera. Agradecimentos: Este trabalho foi financiado por fundos do FEDER através do Programa Operacional Fatores de Competitividade – COMPETE”.
