Structure and Synthesis of a New Indole Alkaloid, 19 (S)-Hydroxy-Nb-methylraumacline, Obtained by the Biotransformation of Ajmaline in Plant Cell Cul…
1992
Abstract From the plant cell suspension cultures of Tauwolfia serpentina Benth ., which were cultivated in the alkaloid-production medium after feeding of ajmaline (1) , a new indole alkaloid 19- ( S )-hydroxy- N b -methylraumacline ( 4 ) was isolated. The structure of 4 first elucidated by spectroscopic analysis was determined by the chemical synthesis from ajmaline ( 1 ).
Mitigating-casi: relation between propositional content and discourse units
2018
El aproximativo casi entraña la inversión polar de su proposición, sin embargo, los usos considerados expletivos presentan valores atenuantes. Este trabajo complementa con un estudio de corpus la descripción teórica del uso expletivo-atenuante en relación con la unidad discursiva de casi en el habla coloquial. La unidad que ocupa en el discurso determina su uso atenuante y supone una prueba efectiva de su naturaleza semántica, al tiempo que aclara ciertas cuestiones de la bibliografía deductiva. This paper explores the mitigating function of Spanish casi and its relation to the discourse units casi fulfills in spoken language. Casi can either entail a polar inversion of the proposition it h…
Part-of-speech labeling for Reuters database
2015
Even if the Vector Space Model used for document representation in information retrieval systems integrates a small quantity of knowledge it continues to be used due to its computational cost, speed execution and simplicity. We try to improve this document representation by adding some syntactic information such as the parts of speech. In this paper, we have evaluated three different tagging algorithms in order to select the most suitable tagger for using it to tag the Reuters dataset. In this work, we have evaluated the taggers using only five different parts of speech: noun, verb, adverb, adjective and others. We considered these particular tags being the most representative for describin…
Organizing Shared Digital Reading in Groups: Optimizing the Affordances of Text and Medium
2019
Children develop their language when they explore and talk about literary texts. In this study, we explore the design of shared digital reading as a basis for critical reflection on the reading situation in an institutional context with its given opportunities and limitations. We examine six videotaped readings of one specific picture book app, with a focus on the strategies used by teachers in early childhood education and care institutions to control children’s access to the medium and the types of verbal engagement (about the story and about the medium) that are generated by these different strategies. We use qualitative and quantitative analysis of video data. A qualitative categorizat…
Finns and Americans Compared on the Immediacy Construct
1991
The Self-assessment of Immediacy Scale was administered to 219 Finnish students and 147 American students. The two groups were not significantly different from each other in perceived nonverbal immediacy. When the men were compared to the women, the women were significantly more immediate.
The role of animacy in online argument interpretation in Mandarin Chinese
2011
The present event-related brain potential (ERPs) study demonstrates that online argument interpretation in verb-final structures in Mandarin Chinese is modulated by two factors: a preference for Undergoer-before-Actor orders and a preference for animate Actor arguments. Participants listened to sentences with NP(animate)-NP(inanimate)-verb or NP(inanimate)-NP(animate)-verb orders embedded in minimal contexts. Sentences were disambiguated towards either an Actor-initial or an Undergoer-initial order by the clause-final verb. Between 450 and 700 ms post verb onset, we observed an anterior negativity for sentences violating both preferences (inanimate-Actor-initial structures) vs. sentences fu…
#MeToo in school: teachers’ and young learners’ lived experience of verbal sexual harassment as a pedagogical opportunity
2020
Based on a case study of verbal sexual harassment experienced by a young female teacher and her 17-year-old student in a Norwegian upper secondary school, this article addresses challenges and strengths of drawing upon negative experiences of ‘lived injustice’ in class, arguing that such experiences can serve as a resource for education about, through and for human rights. Complementing this case study, we discuss a survey we have conducted among secondary school students (N=382), concerning how young learners report being sexually harassed and how often they experience that an adult intervenes in the situation. Combining the theoretical framework of human rights education (HRE) and the con…
Volatile constituents of aerial parts of two Mediterranean species of Inula: Inula crithmoides L. and I. verbascifolia (Willd.) Hausskn. (Asteraceae)
2014
Inula crithmoides L. grows along the Mediterranean coasts and is used as an edible vegetable as the young leaves or shoots are eaten raw, cooked or pickled. Inula verbascifolia (Willd.) Hausskn. is a quite localised species growing mainly along the Adriatic Sea coasts. In this study the volatile components of the aerial part of both species are described. Gas chromatography and gas chromatography mass spectrometry analysis showed the presence of 41 components in I. crithmoides and 75 compounds in I. verbascifolia, respectively, and a very different profile in the composition of the two species. The chemotaxonomy of I. crithmoides, by comparison with other data reported in the literature, is…
Structural considerations on the iridoids as anti-inflammatory agents.
1994
Abstract Twelve iridoid glycosides have been evaluated for their anti-inflammatory activity on two models: the carrageenan-induced mouse paw edema and the TPA-induced mouse ear edema. Loganic acid was the most active (44.4% edema inhibition) on the former test, whereas the catalpol derivative mixture isolated from Scrophularia, aucubin, verbenalin, and loganin, showed the highest activity (from 72.0 to 80.0% edema inhibition) on the latter. The results allowed us to establish the relationship between the structure and anti-inflammatory activity on the basis of the different patterns of substitution, particularly hydroxylation, unsaturation, and acylation.
Atrévete a ironizar: propuesta para la enseñanza de la prosodia y la kinesia de la ironía
2020
La ironía es un fenómeno complejo que puede suponer un verdadero reto para los aprendientes de Español como Lengua Extranjera (ELE). Sin embargo, los enunciados irónicos presentan marcas e indicadores que pueden facilitar al estudiante su aprendizaje. El objetivo de este trabajo es ofrecer una propuesta didáctica para enseñar las marcas prosódicas y kinésicas de la ironía, ante la falta de recursos que aborden estos rasgos. Para ello, nos basamos en los parámetros del método verbo-tonal y adoptamos un enfoque fonocognitivo, que abarca tanto la percepción como la producción de enunciados irónicos. Con la ayuda del programa informático PRAAT, de una metáfora visual y de diversos materiales au…
