CORTESÍA Y LENGUAS DE ESPECIALIDAD ENTRE LO LOCAL Y LO GLOBAL: EL CASO DE LAS RESEÑAS DE HOTELES EN ESPAÑOL E INGLÉS

2015

El presente trabajo analiza el género de la reseña de hoteles en español y en inglés para explorar la evolución de este género a raíz de su internacionalización. El análisis basado en corpus se realiza a través de una comparación monolingüe y bilingüe contrastiva, observando la distribución de estrategias de atenuación e intensificación (Briz, 2001; Albelda, 2007) de los adjetivos con carga semántica negativa en tres tipos de reseñas: reseñas en español publicadas en plataformas nacionales españolas, reseñas en español publicadas en plataformas internacionales, y reseñas en inglés publicadas en plataformas internacionales. Los resultados cuantitativos demuestran que la difusión global de es…

Benchmarking numerical models of brittle thrust wedges

2016

International audience; We report quantitative results from three brittle thrust wedge experiments, comparing numerical resultsdirectly with each other and with corresponding analogue results. We first test whether the participatingcodes reproduce predictions from analytical critical taper theory. Eleven codes pass the stable wedgetest, showing negligible internal deformation and maintaining the initial surface slope upon horizontaltranslation over a frictional interface. Eight codes participated in the unstable wedge test that examinesthe evolution of a wedge by thrust formation from a subcritical state to the critical taper geometry. Thecritical taper is recovered, but the models show two…

Stabilization of Polar Step Edges on Calcite (10.4) by the Adsorption of Congo Red

2015

In this work, we present the stabilization of polar step edges along the [010] direction of calcite (10.4) by the presence of a water-soluble organic molecule, namely Congo Red. While characteristic etch pits are observed on the surface in the absence of the additive, no etch pits can be found in the presence of the additive. Using atomic force microscopy, we can directly follow the restructuring of the surface. Upon addition of Congo Red, the charge-neutral step edges confining the characteristic etch pits vanish, while polar step edges along the [010] direction appear on the surface, which are entirely decorated by well-ordered molecular islands of the additive. After the restructuring ha…

Learning to Read Equine Agency: Sense and Sensitivity at the Intersection of Scientific, Tacit and Situated Knowledges

2021

The aim of this essay is to address the challenges and problems in communicating with horses and interpreting their communication in everyday handling and training situations. We seek ways to learn more about equine communication and agency in the prevention of cruelty against animals and in enhancing animal welfare. We ask how it would be possible to learn to read the subtle signs of equine communication and agency in a sensible, sensitive, and ethical way to increase the health and wellbeing of horses that humans interact with. We have placed this theoretical examination in a multidisciplinary framework that consists of humananimal studies, feminist posthumanities, cultural and literary s…

Hierarchies of knowledge, incommensurabilities and silences in South African ECD policy: Whose knowledge counts?

2017

AbstractPolicy for young children in South Africa is now receiving high-level government support through the ANC’s renewed commitment to redress poverty and inequity and creating ‘a better life for all’ as promised before the 1994 election. In this article, I explore the power relations, knowledge hierarchies and discourses of childhood, family and society in National Curriculum Framework (NCF) as it relates to children’s everyday contexts. I throw light on how the curriculum’s discourses relate to the diverse South African settings, child rearing practices and world-views, and how they interact with normative discourses of South African policy and global early childhood frameworks. The NCF…

Edge Orientation and the Design of Problem-Specific Crossover Operators for the OCST Problem

2012

In the Euclidean optimal communication spanning tree problem, the edges in optimal trees not only have small weights but also point with high probability toward the center of the graph. These characteristics of optimal solutions can be used for the design of problem-specific evolutionary algorithms (EAs). Recombination operators of direct encodings like edge-set and NetDir can be extended such that they prefer not only edges with small distance weights but also edges that point toward the center of the graph. Experimental results show higher performance and robustness in comparison to EAs using existing crossover strategies.

Curved Edge Routing

2001

We consider the problem of drawing a graph where edges are represented by smooth curves between the associated nodes. Previously curved edges were drawn as splines defined by carefully calculated control points. We present a completely different approach where finding an edge is reduced to solving a differential equation. This approach allows to represent the graph drawing aesthetics directly, even the most complex ones denoting the dependencies among the paths.

Highly irregular graphs with extreme numbers of edges

1997

Abstract A simple connected graph is highly irregular if each of its vertices is adjacent only to vertices with distinct degrees. In this paper we find: (1) the greatest number of edges of a highly irregular graph with n vertices, where n is an odd integer (for n even this number is given in [1]), (2) the smallest number of edges of a highly irregular graph of given order.

Step-Edge Induced Anisotropic Domain-Wall Propagation

1999

We report the observation of anisotropic domain-wall propagation in ultrathin magnetic films with perpendicular anisotropy. A controlled density of step edges was introduced which allowed us to quantify its influence on the domain-wall pinning. For a sawtooth arrangement of the step edges the corresponding wall movement resulted in triangular shaped domains. All aspects of this anisotropic domain-wall evolution could be reproduced by a simulation based on a modified Ginzburg-Landau-type soft-spin model.
