Levine's motivic comparison theorem revisited

For a field of characteristic zero, M. Levine has proved that his category of triangulated motives is equivalent to the one constructed by V. Voevodsky. In this paper we show that the strategy of Levine's proof can be applied on every perfect field to the categories of triangulated motives with rational coefficients.Comment: 40 pages, submitte

Las anáforas de Cotidiano del Missale hispano-mozarabicum

Las plegarias eucarísticas o anáforas del tiempo De Gotidiano del actual Missale Hispano-Mozarabicum constituyen una fuente de especial significación para el conocimiento de la teología eucarística del rito hispanomozárabe. Lo que aquí se pretende es una breve introducción y presentación de las características fundamentales de las anáforas cotidianas del misal hispano. Con esto, el lector puede adentrarse en los textos anafóricos del tiempo De Gotidiano o de otros tiempos del misal de 1991

Interpersonality and culture: an approach to the movie review genre

Abstract: this paper investigates the impact of cultural values on the interactional metadiscourse (Hyland and Tse 2004) used in movie reviews drawn from two digital newspapers: the Peninsular-Spanish El País and the British The Guardian. Specifically, the influence of Hall’s (1976) “context dependence” and Hofstede’s (1991) “individualism index” is surveyed. The findings reveal similarities for both corpora due to genre constraints, but cultural differences are also found. The implication of the study is to raise awareness of the importance of interpersonal metadiscourse as a persuasive linguistic element in the teaching and learning of L2 writing skills. Title in Spanish: Interpersonalidad y cultura: una aproximación al género de la reseña de película. Resumen: este estudio investiga el impacto de los valores culturales en el metadiscurso interaccional (Hyland and Tse 2004) empleado en reseñas de películas de dos periódicos digitales: el español peninsular El País y el británico The Guardian. Concretamente, exploramos el nivel de “dependencia contextual” de Hall (1976) e “índice de individualismo” de Hofstede (1991). Los resultados revelan similitudes en ambos corpus debidas a las convenciones del género así como diferencias culturales. La implicación del estudio es resaltar la importancia del metadiscurso interpersonal como elemento lingüístico persuasivo en la enseñanza y el aprendizaje de las destrezas escritas de una segunda lengua. </jats:p

Review of Research in the Field Study of the Stress-Strain State of Concrete-Filled Structures

The paper presents an analytical review of the literature, which reflects the results of national and foreign scientific researches aimed to studying the features of the composition and dosage of components of self compacting concrete as one of the most promising aggregate for modern composite structures. In addition, the results of numerical and experimental researches of stress-strain state of composite structures (concrete-filled tubes) under the influence of various power factors, have been considered. The description and features of existing analytical methods for the determination of the bearing capacity of the considered structures under compression and bendings, have been given. The analysis of deformation model of confined concrete in a composition of the composite structure, as well as non-linear models of steel works with their distinctive features, has been carried out. The main approaches to the finite element modeling of composite structures have been determined

Los valores culturales y su correlación con las estrategias del metadiscurso interaccional en las páginas web de negocios españolas y estadounidenses

The present paper explores the way in which the cultural dimension of individualism is reflected in the interactional discourse of Spanish and us business websites. This cultural dimension is concerned with the way individuals from a particular culture define their own identity and their relationship with other people. Considering the scores of Spain and the US on the individualism index, the objective of this study is twofold: (a) to analyse the type of interactional metadiscourse strategies used on the presentation pages of Spanish and us toy company websites, and (b) to determine whether the individualism index scores of Spaniards and North Americans are reflected in different interactional metadiscourse strategies when companies establish a social relationship and persuade a potential customer to purchase their products. The results obtained confirm that there are important differences in the interactional discourse of this digital genre, which may be a valuable source of information for export companies that wish to introduce their products abroad by means of their business websites.En este estudio se explora en qué medida la dimensión cultural del individualismo se refleja en el discurso interaccional de páginas web de negocios españolas y estadounidenses. Esta dimensión se relaciona con el modo en que los miembros de una cultura conciben su identidad y su relación social con otras personas. Según el índice de valores culturales con que España y los Estados Unidos de América responden a la dimensión cultural del individualismo, en este estudio intento alcanzar dos objetivos: (a) analizar el tipo de estrategias metadiscursivas interaccionales que se emplean en la página de presentación de la empresa en páginas web de negocios españolas y estadounidenses y (b) examinar si el índice de valores culturales individualistas de España y de los Estados Unidos de América se muestra en estrategias metadiscursivas diferentes en el momento de establecer una relación social y persuadir a un posible cliente a comprar los productos de la empresa. Los resultados obtenidos confirman diferencias en el discurso interaccional de este género digital, que pueden ser útiles para empresas exportadoras que desean introducir sus productos en países extranjeros a través de sus webs de negocios

Perverse Nori motives

25 pagesInternational audienceIn this work we show that the Tannakian formalism developed by M. Nori applies to representations of quivers with values in an Abelian category that is Noetherian, Artinian and has with finite dimensional Hom groups. As an application, we define a relative version, modeled after perverse sheaves, of the Abelian category of motives constructed by M. Nori over a field of characteristic embedded in the field of complex numbers

Projection constants of almost-Milyutin spaces

We prove that there exist almost-Milyutin spaces whose projection constants are numbers of the form $1+2\sum_{i=1}^{r}\left(1-\frac{1}{n_{i}}\right)$, where $n_{1},...,n_{r}$ are integers greater than 1. This generalizes our earlier results, where we showed the existence of almost-Milyutin spaces with exact projection constant greater or egual to n, for each positive integer n
