Structure, Properties, and Tissue Localization of Apoplastic α-Glucosidase in Crucifers1

Apoplastic α-glucosidases occur widely in plants but their function is unknown because appropriate substrates in the apoplast have not been identified. Arabidopsis contains at least three α-glucosidase genes; Aglu-1 and Aglu-3 are sequenced and Aglu-2 is known from six expressed sequence tags. Antibodies raised to a portion of Aglu-1 expressed in Escherichia coli recognize two proteins of 96 and 81 kD, respectively, in vegetative tissues of Arabidopsis, broccoli (Brassica oleracea L.), and mustard (Brassica napus L.). The acidic α-glucosidase activity from broccoli flower buds was purified using concanavalin A and ion-exchange chromatography. Two active fractions were resolved and both contained a 96-kD immunoreactive polypeptide. The N-terminal sequence from the 96-kD broccoli α-glucosidase indicated that it corresponds to the Arabidopsis Aglu-2 gene and that approximately 15 kD of the predicted N terminus was cleaved. The 81-kD protein was more abundant than the 96-kD protein, but it was not active with 4-methylumbelliferyl-α-d-glucopyranoside as the substrate and it did not bind to concanavalin A. In situ activity staining using 5-bromo-4-chloro-3-indolyl-α-d-glucopyranoside revealed that the acidic α-glucosidase activity is predominantly located in the outer cortex of broccoli stems and in vascular tissue, especially in leaf traces.

A influência do cão na expressividade emocional de crianças com transtorno do espectro do autismo

O Transtorno do Espectro do Autismo (TEA) inclui um conjunto de sintomas, tais como dificuldade para sustentar contato visual direto e comprometimento da linguagem. Apesar da Terapia Assistida Por Animais (TAA) com cães ser considerada uma modalidade terapêutica eficaz para promover o desenvolvimento de pessoas com TEA, ainda não são se sabe quais características dos cães possibilitam alcançar sucesso na terapia. Esta análise quantitativa tem como objetivo verificar o impacto de abordagens laterais e frontais de cães e humanos nas expressões emocionais de alegria e rejeição de crianças com TEA. Através da análise de vídeos de TAA, foram mensuradas duração e frequência das abordagens laterais e frontais de cães e humanos dirigidas às crianças para comparar possíveis diferenças entre ambos e também para verificar se a abordagem escolhida afetava o tipo de expressão emocional exibida pela criança. Os participantes deste projeto foram 11 crianças, 8 do sexo masculino e 3 do sexo feminino, entre 5 e 11 anos. Seis crianças foram atendidas por uma psicóloga, uma condutora e um Border Collie. O segundo grupo era composto pela mesma psicóloga, uma condutora e uma Golden Retriever. Escalas de avaliação foram aplicadas para confirmar o diagnóstico de TEA. Os cães foram previamente avaliados e treinados por uma instituição que atua na área de TAA. Cinco minutos de 8 sessões foram analisadas: um bloco de seis sessões com o cão, uma sessão anterior e uma sessão posterior a este bloco. Para verificar possíveis diferenças temperamentais entre cães, o C-barq (Canine Behavioral Assesment & Research Questionnaire) foi aplicado para analisar o temperamento de ambos. Embora esta análise tenha demonstrado diferenças em relação às categorias busca de atenção e nível de energia dos cães, não foram verificadas diferenças estatísticas entre os cães, em relação às variáveis analisadas neste estudo. Na comparação entre cães e humanos, os cães foram mais efetivos para conseguir expressões de alegria independentemente do tipo de abordagem escolhida. Comparando-se o tempo de abordagem de cães e humanos até obterem expressão emocional das crianças, observou-se uma importante diferença estatística. Os resultados sugerem que os cães exibiram menor latência que humanos para todas expressões emocionais analisadas: alegria (2= 7,312, p=0,007), de rejeição (2= 11,277, p-0,001) e neutras (2=9,097, p=0,043). Além disso, os resultados sugerem que, no contexto da TAA, não há relação entre abordagem lateral ou frontal e expressões de alegria, rejeição ou neutras de crianças com TEA. As expressões de alegria foram mais frequentes diante das abordagens laterais dos cães do que das abordagens frontais, no entanto não foi verificada significância estatística. Em relação aos humanos também não foi verificada preferência por uma abordagem especifica. Assim, os resultados sugerem que a latência para a exibição de uma expressão emocional das crianças depende mais de quem aborda do que do posicionamento lateral ou frontal quando a abordagem é realizada

Apuntes sobre la percepción subconsciente en el cine: el ejemplo de Alien, el octavo pasajero (1979) y su propuesta orgánica de atracción/repulsión

En una revisión profunda en la que se aportan datos hasta ahora inéditos, el presente artículo analiza nuevas claves de por qué la película Alien, el octavo pasajero (Ridley Scott, 1979), ha causado una atracción sobredimensionada del espectador en su estreno y reposición a lo largo de más de tres décadas. Se propone la tesis de que el film emplea un conjunto de símbolos audiovisuales ocultos o semi-ocultos que provocan sensaciones de placer/displacer (eros y tanatos) y son las causantes directas de sus nutridas afinidades. Se explicita además cómo en el diseño/ presentación de un universo alienígena aparentemente nuevo (respecto al cine de ciencia ficción precedente) el espectador asume una mímesis identificativa y orgánica que se introduce en las profundidades del inconsciente, despertando un interés sorprendente entre audiencias de diferentes generaciones y edades. Se analiza el fenómeno subliminal o subconsciente en el cine, desde el punto de vista de la percepción, a partir de los experimentos publicitarios de los años 50 en una sala de exhibición de los Estados Unidos. También se estudia por primera vez el curioso paralelismo del argumento de la película con el impacto mediático previo y simultáneo del primer bebé probeta nacido el 25 de julio de 1978, en pleno inicio del rodaje de este film en los estudios londinenses Shepperton.

Sighted volunteers’ motivations to assist people with visual impairments in freetime sport activities

Since the changing of the political and economic system in 1989-1990 in Hungary, volunteer movements have appeared all over the country. Volunteers of different ages and socioeconomic backgrounds are engaged in a wide range of activities, wishing to add values to the lives of others in need, hoping to improve their micro or/and macro environment. Volunteering has also appeared in the field of sport, and the work of a large number of nongovernmental sport organisations is strongly dependent on volunteers’ participation. In the socialist era disability sports were neglected by the state. The new democratic state has been paying increasing attention to disability sports and volunteers have been a great asset in improving the accessibility of spare time sport activities. The present empirical research investigates which factors motivate sighted volunteers to join Hungarian Sports and Leisure Association for the Visually Impaired (Látássérültek Szabadidős Sportegyesülete, LÁSS). Results confirm that joining LÁSS was in few cases (N=3) attributed to having parental or other family relations with blind or partially sighted people. Respondents unanimously admit to have a wish to share the joy of physical activity with their visually impaired peers.

Poems copied by James Diman, ca. 1730-1733

Small pamphlet-sized notebook containing handwritten transcriptions of three poems copied by James Diman, likely in the early 1730s. The notebook contains "The Catholic Remedy. to ye Tune of To all you Ladies, not at land &c.," "Father Ab--y's Will. Col. Sweeper Camb: Dec. 1731," and "The Poet's Lamentation for ye Loss of his cat, w'ch he used to call his Muse" copied from the London Magazine, November 1733. The "Catholic Remedy" begins "You Peope who desire to mend / your Desperate Estate..." and includes the note, "Made upon A--D--'s goving over to take orders. The note refers to the voyage of Addington Davenport (Harvard AB 1719) to England join the priesthood of the Church of England in 1730. "Father Ab--y's Will" begins "To my dear Wife, / My joy and Life..." and was a humorous poem published in 1731 after the death of Harvard College Sweeper Matthew Abdy, and attributed to Jonathan Seccombe (Harvard AB 1728). The "Poet's Lamentation" begins "Oppress'd with Grief, in heavy strains I mourn..." and was written by Joseph Green (Harvard AB 1726) as a parody of a psalm composed by Mather Byles (Harvard AB 1725). Pages 10-12, holding part of "Father Ab--y's Will" are missing, and pages 13-15 are no longer attached to the item.

Mapping Emotion Terms into Affective Space: Further Evidence for a Four-Dimensional Structure

Recent empirical work on the semantics of emotion terms across many different cultures and languages, using a theoretical componential approach, suggested that four dimensions are needed to parsimoniously describe the semantic space of the emotion domain as reflected in emotion terms (Fontaine, Scherer, Roesch, & Ellsworth, 2007; Fontaine, Scherer, & Soriano, 2013). In addition to valence, power, and arousal, a novelty dimension was discovered that mostly differentiated surprise from other emotions. Here, we further explore the existence and nature of the fourth dimension in semantic emotion space using a much larger and much more representative set of emotion terms. A group of 156 participants each rated 10 out of a set of 80 French emotion terms with respect to semantic meaning. The meaning of an emotion term was evaluated with respect to 68 emotion features representing the appraisal, action tendency, bodily reaction, expression, and feeling components of the emotion process. A principal component analysis confirmed the four-dimensional valence, power, arousal, and novelty structure. Moreover, this larger and much more representative set of emotion terms revealed that the novelty dimension not only differentiates surprise terms from other emotion terms, but also identifies substantial variation within the fear and joy emotion families.
