“Stories from No-Man’s Land?” Situated language learning through the use of role models in the context of international Higher Education

2012

This article discusses the value of role models in the language acquisition process of international students following an English as Medium of Instruction (EMI) programme in the Netherlands. Narrative interpretations of qualitative data provide insights into the identity work involved in the use of role models and the impact that this work has on the participation of learners in the ir core learning community and other communities. The article compares the use of role models in the cases of three students. These learning experiences were recorded through Language Learning Histories (Murphey, Chen & Chen: 2004), semi -structured interviews and journal entries. Analysis is grounded in the th…

Cuidado y responsabilidad: de Hans Jonas a Carol Gilligan

2019

El objetivo de este trabajo es situar la ética del cuidado en contexto de las éticas de la responsabilidad. Para ello analizamos la orientación hacia el cuidado en las éticas de la responsabilidad mostrando la transición de una responsabilidad limitada por el cálculo consecuencialista en la actividad política, a una responsabilidad integral exigida por la preservación de la naturaleza ante los desafíos de la ciencia y la técnica. Interpretamos la aportación de Carol Gilligan en términos de «provocación » a la ética contemporánea para que el cuidado no sea únicamente una categoría sentimental o afectiva sino una categoría con la que reconstruir reflexivamente la justicia social. Esta interpr…

A Navigation and Augmented Reality System for Visually Impaired People

2021

In recent years, we have assisted with an impressive advance in augmented reality systems and computer vision algorithms, based on image processing and artificial intelligence. Thanks to these technologies, mainstream smartphones are able to estimate their own motion in 3D space with high accuracy. In this paper, we exploit such technologies to support the autonomous mobility of people with visual disabilities, identifying pre-defined virtual paths and providing context information, reducing the distance between the digital and real worlds. In particular, we present ARIANNA+, an extension of ARIANNA, a system explicitly designed for visually impaired people for indoor and outdoor localizati…

Feminisme neoliberal: un oxímoron?

2018

Neoliberal Feminism: An Oxymoron? Resum: En el present escrit tractem d’aproximar-nos al concepte de “feminisme neoliberal” per tal d’identificar-ne les principals caracteristiques i contradiccions. Aixi doncs, l’objectiu principal que ens plantegem tracta de discernir si es possible, atenent al context actual de desenvolupament del moviment feminista en un marc neoliberal, parlar de “feminisme neoliberal”, o si pel contrari, es tracta d’un concepte que es en si mateix un oximoron. Partint del sentit de transformacio social cap a la justicia intrinsec al moviment feminista, tractarem de veure com la logica neoliberal ha condicionat o influenciat en aquest moviment en l’actualitat. Alhora es…

Performance Evaluation for a Sustainable Supply Chain Management System in the Automotive Industry Using Artificial Intelligence

2020

Increasing the sustainability of a system can be achieved by evaluating the system, identifying the issues and their root cause and solving them. Performance evaluation translates into key performance indicators (KPIs) with a high impact on increasing overall efficacy and efficiency. As the pool of KPIs has increased over time in the context of evaluating the supply chain management (SCM) system&rsquo

New orbital ephemerides for the dipping source 4U 1323-619: Constraining the distance to the source

2016

4U 1323-619 is a low mass X-ray binary system that shows type I X-ray bursts and dips. The most accurate estimation of the orbital period is 2.941923(36) hrs and a distance from the source that is lower than 11 kpc has been proposed. We aim to obtain the orbital ephemeris, the orbital period of the system, as well as its derivative to compare the observed luminosity with that predicted by the theory of secular evolution. We took the advantage of about 26 years of X-ray data and grouped the selected observations when close in time. We folded the light curves and used the timing technique, obtaining 12 dip arrival times. We fit the delays of the dip arrival times both with a linear and a quad…

La selección de las noticias en el entorno de un centro de documentación de información de actualidad

2002

In information retrieval systems operation, lack of adequate selection criteria originates information overload and has negative consequences in relevance judgments. In the context of a news reference service, three leveis in the selection process are proposed. The first one relates to the type of sources covered by the system, the second set of criteria determines which publications are included in the process of document analysis. The last one applies to the selection of individual documents based on their informative content. La falta de criterios idóneos de selección puede provocar un grave problema de saturación informativa, lo que repercute negativamente en la búsqueda posterior de in…

Rearrangement of N-(3-pyridyl)nitramine

2009

AbstractContrary to other N-(pyridyl)nitramines, the title compound cannot be rearranged to 3-amino-2-nitropyridine or other isomers. Hypothetical products of its transformation under influence of concentrated sulphuric acid, viz. 3-hydroxypyridine, 3,3′-azoxypyridine and 3,3′-azopyridine, were obtained from 3-nitro- and 3-aminopyridine in oxidation and reduction reactions. N-(3-Pyridyl)nitramine was prepared and rearranged in concentrated sulphuric acid. 3-Hydroxypyridine and 3,3′-azoxypyridine were isolated from the reaction mixture, other products were identified by the HPLC and GCMS methods. The results indicate that N-(3-pyridyl)hydroxylamine is an intermediate formed from N-(3-pyridyl…
