    Abstract The present End-of-degree project took the existing lack of correlation between the vast and prosperous range of varieties of English spoken worldwide and its scarce implication in the production of pedagogical materials utilised for the teaching of English as a Foreign Language (EFL) as its point of departure. It sought to explore and bring to light the practicability and convenience of implicating other World Englishes in education, apart from the so called “Standard British English” and “Standard American English” on which the majority of methods and textbooks are based, so as to offer students more realistic views of the language and broaden their communicative possibilities in accordance with the global status English holds currently. For this purpose, the present study trusted on the personal proposal, elaboration and in-class implementation of a series of pedagogical activities which were meticulously designed to demonstrate the efficacy and benefits of multicultural approaches in the teaching of EFL. Overall, conclusions indicated that the project was successful in raising awareness of the exposed situation among students who took part in it as well as it revealed other positive inferences of stimulating their levels of reflection on this matter. Resumen El presente Trabajo Fin de Grado toma como punto de partida la falta de correlación que existe entre el vasto y próspero repertorio de variedades de inglés del mundo y su escasa implicación en la elaboración de materiales pedagógicos utilizados para la enseñanza del inglés como lengua extranjera. Se ha pretendido explorar y demostrar la viabilidad y conveniencia de integrar otras variedades de inglés, además de las variedades británica y americana estándar, en las que la mayoría de libros y métodos se basan, para así ofrecer a los estudiantes visiones más realistas del idioma y ampliar sus posibilidades comunicativas en concordancia con el estatus global que el inglés ostenta hoy en día. Con este propósito, el estudio confió en la propuesta personal, elaboración e implementación de primera mano de una serie de actividades pedagógicas meticulosamente elaboradas para demostrar la eficacia y los beneficios de los enfoques multiculturales en la enseñanza del inglés como lengua extranjera. En general, las conclusiones obtenidas indican que el proyecto ha logrado despertar conciencia de la situación expuesta entre los estudiantes que han participado en él, y ha revelado otros aspectos positivos de haber estimulado sus niveles de reflexión sobre este tema

    Surf and turf: animal resources in the human diet in Cantabrian Spain during the Mesolithic (11.5 – 7.5 Ky cal. BP)

    Get PDF
    The beginning of the Holocene involved a series of climatic and environmental changes that affected the ways of life of the last hunter-gatherers. In the case of the Spanish Cantabrian region, these changes transformed the material culture and the way human groups interacted with the environment and, therefore, the subsistence strategies of the end of the Upper Pleistocene. In terms of the use of faunal resources, this period was characterised by an increase in the exploitation of coastal resources, mainly molluscs, but also crustaceans and echinoderms, which make up the so-called “shell middens”, while at the same time the percentage of macromammals was reduced and animals considered to have a “low energy range” were introduced into the diet. In this paper we assess the role played by each of these animal resources in the subsistence of Mesolithic human groups, determining their nutritional contribution and establishing a prey ranking based on the caloric intake of each resource. For this purpose, we collected archaeofaunal data from 14 sites from recent archaeological excavations with levels dated between ca. 11.5 and 7.5 ky cal BP in which the consumption of vertebrates and invertebrates is documented. At each of these sites we analysed diversity, homogeneity and species richness using Simpson's and Shannon's indexes, as well as the effective numbers of species for terrestrial and coastal resources, assessing the relationship between the two. With the palaeoecological and palaeoeconomic data from these archaeological sites (most of them located in caves), we estimate the weight that the different animal resources consumed by the last hunter-gatherer communities of the Cantabrian region had in their diet.Programa Estatal de Fomento de Generación de Conocimiento y Fortalecimiento Científico y Tecnológico of the Spanish Ministry of Science and Innovatio

    The Study of Affective Polarization: A Methodological Stance

    Get PDF
    En la última década, la literatura en ciencia política ha introducido un nuevo concepto denominado “polarización afectiva” para caracterizar una forma de polarización política en la que predominan actitudes de favoritismo por el propio grupo y desprecio hacia el grupo rival. Este nuevo concepto nace en un escenario de fuerte tensión entre grupos políticos rivales en diversas democracias modernas. En este artículo, presentamos una revisión sistemática y crítica de la literatura empírica sobre polarización afectiva. El objetivo es poder realizar sugerencias metodológicas a tener en cuenta en la futura investigación en esta área. Como punto positivo, destacamos la variedad de medidas que se han utilizado para medir la polarización afectiva, desde medidas explícitas e implícitas hasta conductuales. Criticamos la ambigüedad con la que viene siendo utilizado el concepto de polarización afectiva, sugiriendo maneras de sobrepasar los problemas identificados. También señalamos la necesidad de una definición precisa de los objetos hacia los cuales las actitudes van a ser medidas. Por último, resaltamos la necesidad de mayores esfuerzos para establecer la validez convergente y discriminante del constructo de polarización afectiva.In the last decade, the political science literature has introduced a new concept called “affective polarization” to describe a form of political polarization in which attitudes of favoritism for one’s own group and contempt for the rival group predominate. This new concept is born in the context of strong tension between rival political groups in different modern democracies. In this article, we present a systematic and criticalreview of theempirical literature on affective polarization. The goal is to present methodological suggestions to be taken into account in future research in this area. As a positive aspect, we highlight the variety of measures that have been used to measure affective polarization, from explicit and implicit to behavioral measures. We criticize the ambiguity with which the concept is being used, suggesting ways to overcome the identified problems. We also point out the need for precise definition of the objects towards which political attitudes are to be measured. Finally, we highlight the need for further efforts to establish the convergent and discriminant validity of the affective polarization construct.Fil: Freidin, Esteban.

    [EN] Aim of study: Governance and the knowledge and innovation system (KIS) are interrelated concepts. Knowledge management best practices are linked to KIS performance. This article explores the governance of the leading research, development, and innovation institutes in Ibero-American agriculture, food, and agro-industry sector. The paper reports mapping of the governance of 20 agricultural research institutes. Area of study: Latin America and the Caribbean, Spain and Portugal. Material and methods: In total, 51 strategic objectives for effective governance were identified. Self-evaluation by the National Agricultural Research Institutes (NARIs) was validated at a workshop backed by FONTAGRO, a cooperation mechanism amongst Latin American and the Caribbean countries, Portugal and Spain, and the Ibero-American Network of NARIs. Main results: As a strength, the key dimension of NARIs appears to be coordination and cooperation. This result was acknowledged in the internal and external evaluations and supports previous research on the relevance of innovation networks in Latin America. By contrast, as a challenge, the key dimension appears to be demand articulation, followed closely by capacity building. Most of the institutes are also well-positioned to develop deeper ties with social and environmental challenges. Research highlights: In the medium and long term, NARIs should make efforts to improve the processes of organizational evaluation and learning, demand articulation, and strategic direction of the institutions. Improvement in management processes, in addition to best practices for social responsibility and gender equality, appear to be short-term priorities.American Development Bank and the Knowledge Partnership Korea Fund for Technology and Innovation (KPK).

    An integrative methodology based on protein-protein interaction networks for identification and functional annotation of disease-relevant genes applied to channelopathies

    Get PDF
    Biologically data-driven networks have become powerful analytical tools that handle massive, heterogeneous datasets generated from biomedical fields. Protein-protein interaction networks can identify the most relevant structures directly tied to biological functions. Functional enrichments can then be performed based on these structural aspects of gene relationships for the study of channelopathies. Channelopathies refer to a complex group of disorders resulting from dysfunctional ion channels with distinct polygenic manifestations. This study presents a semi-automatic workflow using protein-protein interaction networks that can identify the most relevant genes and their biological processes and pathways in channelopathies to better understand their etiopathogenesis. In addition, the clinical manifestations that are strongly associated with these genes are also identified as the most characteristic in this complex group of diseases. This research provides a systems biology approach to extract information from interaction networks of gene expression. We show how large-scale computational integration of heterogeneous datasets, PPI network analyses, functional databases and published literature may support the detection and assessment of possible potential therapeutic targets in the disease. Applying our workflow makes it feasible to spot the most relevant genes and unknown relationships in channelopathies and shows its potential as a first-step approach to identify both genes and functional interactions in clinical-knowledge scenarios of target diseases.This work was supported by funds from MINECO-FEDER (TIN2016–81041-R to E.R.), European Human Brain Project SGA2 (H2020-RIA 785907 to M.J.S.), Junta de Andalucía (BIO-302 to F.J.E.) and MEIC (Systems Medicine Excellence Network, SAF2015–70270-REDT to F.J.E.)

    Introduction: Acute respiratory infection is one of the most significant causes of morbidity in Bogota, and its burden of disease has increased in association with climate variability.Objective: The aim of the study was to evaluate weekly trends of acute respiratory infection in relation to meteorological variables (temperature, relative humidity and cumulative rainfall) in Bogota during 2011 and 2012.Materials and methods: Epidemiological and meteorological data from 104 weeks were gathered. Temporal variability was taken into account including previous weeks and spatial variability was considered by studying each zone of the city separately (north, south, east, west). Statistical analysis was performed through Poisson dynamic regression models.Results: The relative humidity had the greater impact on acute respiratory infection and its effects lasted between 8 to 10 weeks. Cumulative rainfall had effects only in the east zone, while the temperature presented mild effects across the four different zones of the city.Conclusion: Such results are the first step for the design of health-related early warning systems associated with climate variability.Introducción. La enfermedad respiratoria es una de las principales causas de morbilidad en Bogotá y los efectos de la variabilidad climática se han reflejado en un aumento del número de casos.Objetivo. En el presente estudio se analizó el comportamiento semanal de la enfermedad respiratoria aguda en Bogotá y se asoció con las variables climatológicas de temperatura, humedad relativa y precipitación, analizando su impacto en la aparición de casos en la ciudad.Materiales y métodos. El análisis se llevó a cabo mediante la estimación de modelos de regresión de Poisson, con datos epidemiológicos de 104 semanas correspondientes a los años 2011 y 2012. La variabilidad climática temporal se analizó considerando los efectos de las variables en semanas anteriores y, para el análisis de la variabilidad espacial, la ciudad se dividió en cuatro zonas: norte, sur, oriente y occidente.Resultados. Los resultados de las correlaciones cruzadas demostraron que en tres de las cuatro zonas la humedad relativa tenía un mayor impacto sobre los casos de enfermedad respiratoria aguda y su efecto persistía hasta por ocho y diez semanas. La precipitación, por el contrario, tuvo impacto únicamente en la zona oriente, mientras que la temperatura tuvo efectos moderados en todas las zonas.Conclusión. Debido al componente dinámico de estos modelos, los resultados son un primer paso para el diseño de un sistema de alerta temprana en salud que tome en cuenta la variabilidad climática

    The persistence of red deer (Cervus elaphus) in the human diet during the Lower Magdalenian in northern Spain: Insights from El Cierro cave (Asturias, Spain)

    Get PDF
    he dominance of red deer in Magdalenian records in Cantabrian Spain is a well-studied issue. Given the great accumulations of this species in those deposits, researchers have offered diverse interpretations of the phenomenon, related to ecology, orography or ethology. However, fewer papers carry out comparative intra-site analysis, which is able to document the existence of changes or continuities in the subsistence strategies at an archaeological site. The aim of this paper is to present the results of the archaeozoological analysis of Levels F and G in El Cierro cave (Asturias, Spain), both of them dated during Greenland Stadial 2, in the Lower Magdalenian (15,460 ± 75 and 15,580 ± 75 BP, respectively). Similar percentages of mammals have been documented in the two levels, as well as the same meat and fat consumption and processing strategies. Thus, this paper intends to determine how much energy red deer supplied to the diet of the humans that inhabited El Cierro, in comparison with other hunted and consumed fauna during the Lower Magdalenian. This study highlights the continuity of exploitation patterns of faunal resources in El Cierro cave during the Lower Magdalenian. This continuity is specifically seen in red deer, since the geographic characteristics of the Sella Valley, the abundance of the biotype, and the economic profitability of this species made it the main resource of animal origin for the hunter-gatherers at that site.This research was undertaken in the context of the Spanish projects HAR2014-51830-P funded by the Programa Nacional de Humanidades in the R&D Plan of the Spanish Ministry of Science and Innovation, and HAR2017-82557-P, funded by the Programa Estatal de Fomento de la Investigación Científica y Técnica de Excelencia, of the Spanish Ministry of Economy, Industry and Competitiveness, and PhD scholarship Junta de Castilla y León and Fondo Social Europeo (R.
