Actions de tores algébriques sur des corps de caractéristique zéro

2023

Over an algebraically closed field of characteristic zero, normal affine varieties endowed with an effective torus action were described by Altmann and Hausen in 2006 by a geometrico-combinatorial presentation.Using Galois descent tools, we extend this presentation to the case where the ground field is an arbitrary field of characteristic zero. In this context, the acting torus may be non split and may have non-trivial torsors, thus we need additional data to encode such varieties. We provide some situations where the generalized Altmann-Hausen presentation simplifies. For instance, if the acting torus is split, we recover mutatis mutandis the original Altmann-Hausen presentation. Finally, …

Online platforms to teach Nutrition Education to children: a non-systematic review.

2016

espanolIntroduccion: la obesidad infantil es actualmente considerada un problema a nivel global. La educacion nutricional (EN) ha sido identifi cada como un factor para prevenir el sobrepeso y la obesidad en los ninos. Durante los ultimos anos se ha incrementado el interes en metodos novedosos para ensenar este conocimiento a los ninos, especialmente a traves del uso de Internet. Objetivo: revisar y analizar la evidencia disponible con respecto a los programas de EN dirigidos a ninos a traves del uso de Internet. Resultados: se identifi caron 3 formatos para transferir EN a ninos a traves del uso de Internet: plataformas disenadas para comunicarse con otros ninos o con profesionales, plataf…

One-bond 1 J (15 N,H) coupling constants at sp2 -hybridized nitrogen of Schiff bases, enaminones and similar compounds: A theoretical study

2020

1 J(15 N,H) coupling constants for enaminones and NH-forms of intramolecularly hydrogen-bonded Schiff bases as model compounds for sp2 -hybridized nitrogen atoms are evaluated using density functional theory (DFT) to find the optimal functionals and basis sets. Ammonia is used as a test molecule and its one-bond coupling constant is compared with experiment. A methylamine Schiff base of a truncated molecule of gossypol is used for checking the performance of selected B3LYP, O3LYP, PBE, BHandH, and APFD density functionals and standard, modified, and dedicated basis sets for coupling constants. Both in vacuum and in chloroform, modeled by the simple continuum model of solvent, the modified b…

Producción de personas, reproducción de representaciones. Reflexiones sobre dos programas de capacitación en liderazgo

2020

The present paper addresses the question of the role Executive Education performs in the strengthening and reproduction of neoliberal ideology. It aims to critically reflect on the way selected contents and teaching activities operate jointly enabling or inhibiting certain perspectives regarding work in organizations. Two Leadership training programs are analyzed in this article, currently delivered by the two most prestigious business schools in Argentina: IAE Business School, and Torcuato Di Tella Business School. I begin with a general description of each one and proceed analyzing their educational proposals. Finally, the critical review reveals their consistency with a set of social rep…

Health Insurance Reforms and Health Policies in Rural China

2016

Since the early 2000s, the Chinese government has undertaken a series of reforms in the health sector. Among these, the three most important have been concerned with medical insurance, hospital administration, and pharmaceutical policies. The aims of these reforms were to extend health insurance coverage, to increase the activities and the efficiency of the health establishments, and to improve patient care. This article focuses on two components of these reforms: the development of health insurance in rural areas and the policy on essential medicines in conjunction with hospital reforms. Our longstanding co-operation with a research team from Weifang University and with the Weifang Health …

Commenting on Historical Writings in Medieval Latin Europe : A Reconnaissance

2015

Modern scholarship seems to undervalue medieval commentaries on historical writings. This article intends to bring this phenomenon to scholars’ attention by providing a preliminary overview of the forms and subjects of such commentaries. It examines various types of evidence including not only a few commentaries proper (Nicolas Trevet’s on Livy and John of Dąbrówka’s on Vincent of Cracow), but also different apparatus consisting of more or less systematic interlinear and marginal glosses and commentary-like additions to vernacular translations, mostly of Italian and French origin. It begins by considering various consultation-related signs and annotations, such as cross-references. Then, it…

Fashion and Eroticism Men's Underwear in the Context of Eroticism

2001

What is the process when historically obviously neutral things are becoming loaded with mental meanings, associations and qualities, getting a new turn of expression? The article deals with the changing of men’s underwear from garments of pure utility to high fashionable, visible things. The context in which the change has taken place, the language which supports the new meanings, the forms, colours and use of the “unmentionable” are studied from an ethnological viewpoint. The author emphasises the aspects of new adaptations of the meaning of fashion in relation to changing gender roles, new ideals of the body and new mechanisms in consumer culture.

The exterior derivative as a Killing vector field

1996

Among all the homogeneous Riemannian graded metrics on the algebra of differential forms, those for which the exterior derivative is a Killing graded vector field are characterized. It is shown that all of them are odd, and are naturally associated to an underlying smooth Riemannian metric. It is also shown that all of them are Ricci-flat in the graded sense, and have a graded Laplacian operator that annihilates the whole algebra of differential forms.

Ausencias relevantes en la teoria del curriculum.

2020

Se señalan en el artículo algunas ausencias significativas sobre el modo en que la teoría se ha venido enfrentando al currículum, con especial énfasis sobre lo ocurrido en el contexto español. La historia política del currículum, la mirada desde estudios culturales, la producción de los regímenes de verdad en el currículum, la falta de problematización de las narrativas modernas que inspiran e impregnan la producción curricular o la oportunidad de considerar la ciudad como currículum son algunos de los aspectos que se comentan. Some significant absences are pointed out in the article about the way in which the theory has been confronting the curriculum, with special emphasis on what happene…
