William Conyngham and the Roman theater of Sagunto

Los viajeros ingleses, que llegaron a la españa del siglo xviii, tenían como objetivo el desarrollo de actividades alejadas del estudio de las antigüedades. Sin embargo, la mayoría visitaban, dibujaban y estudiaban nuestros restos; incluso, en algunas oc

Influence of the notch-sharpening technique on styrene-acrylonitrile fracture behavior

The Centre Catala del Plastic and Universidad Rey Juan Carlos laboratories joined forces to investigate the effect of the notch-sharpening technique on the fracture parameters of styrene-acrylonitrile. Contact notch-sharpening techniques, such as razor tapping, razor sliding, and razor broaching, and a noncontact procedure, femtolaser, were analyzed. The fracture values of the samples with notches sharpened via contact techniques were divided into two groups: one with pop-in and the other with no pop-in in the load-displacement records; this resulted in the lowest and highest fracture toughnesses, respectively. The fracture parameters of the specimens with notches sharpened via a femtolaser were between those of the samples with notches sharpened via contact procedures in which pop-in occurred and those in which it did not. To explain these results, the crack front of the nontested specimens after sharpening was investigated in depth, we identified the type of damage and measured its size and the crack tip radii. The morphology of the crack front was related to the fractographic study.Postprint (author's final draft

La Gestión de la Educación Superior Universitaria como Derecho Humano y Bien Público Social

Se presentan los instrumentos y mecanismos institucionales que deberían ser creados o mejorados para revertir preservando la calidad - la excesiva disparidad entre los indicadores de entrada y salida a las carreras de grado de la Facultad Regional Delta de la Universidad Tecnológica Nacional, y por extensión a las Facultades de Ingeniería de América del Sur Se analizan los objetivos e impactos de las acciones de gestión académica propuestas para los factores incidentes en la permanencia de alumnos que se definen y caracterizan con un claro sentido de origen en el seno de un grupo de investigación de una institución definida, pero también con una intención de buscar elementos comunes para pensar los problemas de deserción y desgranamiento, de gran importancia estratégica en nuestra región. Año tras año se registra un crecimiento de la matrícula, pero también se observa que no aumenta proporcionalmente la tasa de graduación. La universidad masiva plantea desafíos complejos que van a exigir la aplicación de instrumentos sofisticados para lograr obtener información relevante que permita formular los diagnósticos certeros y las herramientas adecuadas que mejoren las tasas de permanencia y graduación desde una perspectiva inclusiva

Influence of COVID on the Educational Use of Social Media by Students of Teaching Degrees

The situation caused by SARS-CoV-2 has resulted in the intensive use of technology in all fields, including education and interactions between students. This research seeks to identify changes in the way social media have been used for educational purposes by students of teaching degrees both before and after lockdown. Based on an online survey administered to a sample of 524 students from different Spanish universities in which it has been observed how their use has generally been very similar, although significant differences have been detected according to the kind of university. In this capacity, the use of social media for academic purposes has increased in universities offering traditional classroom based courses, while it has remained the same in virtual universities which, due to their particular idiosyncrasies, have not been directly affected

Communication strategies in the climate change debate on Facebook. Discourse on the Madrid Climate Summit (COP 25)

Climate change (CC) has become a topic of great interest in traditional and social media, two valuable sources of information that contribute to discussion on current affairs. Facebook is the social network with the most users in the world and also promotes mobilization, which makes it a platform of great interest for the study of CC communication strategies. The aim of this study is to analyse the content of the messages on CC posted on Facebook by prominent users: the relevance of the topic in the posts as a whole, objectives pursued, type of discourse and the emotions associated with messages. After validating a selection of 10 accounts (Greta Thunberg, Donald Trump, Scott Morrison, Alexandria Ocasio-Cortez, Extinction Rebellion USA, Justin Trudeau, Bernie Sanders, United Nations, Extinction Rebellion UK and Jane Fonda), the methodology was based on content analysis applied to messages on CC (n = 599) posted on Facebook by the selected accounts between 1 November 2019 and 10 January 2020, the period covering the Madrid Climate Summit (COP 25, held in 2019). The results revealed different CC communication strategies. Regarding the presence of CC as a topic, we observed three different strategies: omission, simple mention and high presence. In terms of discourse, we noticed two different strategies: an emotional strategy that was more successful at generating interaction with others, and an analytical strategy that was generally more belligerent in its fight against CC

Más allá de la brecha salarial

Existe un elevado interés en la actualidad para identificar cuáles son los motivos que justifican una persistencia tan elevada de diferencias salariales entre hombres y mujeres. En este sentido, son muchos los ámbitos de actividad en los que las discriminaciones van desapareciendo; no obstante, la brecha salarial continua. Existen visiones alternativas sobre las razones de esta discriminación, pero en este trabajo se pretende explorar la posibilidad de que dichas diferencias pueden estar relacionadas (al menos en parte) con diferentes actitudes y/o estrategias en relación con la formación; incluyéndose dentro del concepto “formación” la decisión de estudiar o no, el nivel de estudios adquirido, la formación continuada o no reglada o la inserción laboral. Para ello se analizarán tres fuentes de información: dos bases de datos, una sobre la participación en la educación de los individuos españoles y otra sobre la inserción laboral de los estudiantes universitarios; esto complementado con una exploración de concienciación en torno al contexto de brecha salarial, inserción laboral o igualdad.Currently exists an increasing interest to identify the possible reasons that could justify such a high persistence of wage differences between men and women. In this sense, there are many areas of activity in which discriminations are disappearing. However, the pay gap continues. There are alternative point of views on the reasons for this discrimination, but this paper aims to explore the possibility that these differences may be related (at least in part) to different attitudes and / or strategies in relation to the formation each individual has. Including within the concept "formation" the decision to study or not, the level of studies acquired, the continuous or non-regulated training or the labour insertion. To do so, three sources of information will be analyzed: two databases, one on the participation in the education of Spanish individuals and another on the labour insertion of university students. This is complemented by an exploration of awareness around the context of the pay gap, labour insertion or equality

América Latina y el Acuerdo de París: sentando las bases para una gobernanza transnacional efectiva (Coyuntura)

Between 2010 and 2013, Latin America became indebt with six dollars for each dollar that had received as a donation for climate projects. New data (2013-2014) given by the Organization for Economic Co-operation and Development (OECD), showed that this relation has decreased to 3.6 dollars of credit for each dollar that has been donated. However, the omission of the contributions of developing countries persists in the source of information, so the amplitude of the financing gap is still unknown, as well as who is assuming the bill for the mitigation and adaptation of the phenomenon. This article examines the financial climate flows to the region, between 2010 and 2013, and the resources for the REDD+ mechanism. The aim is to draw the prevailing governance model in the region and to establish recommendations vis-à-vis the new Protocol.Entre 2010 y 2013, América Latina se endeudó en seis dólares por cada dólar que recibió como donación para proyectos para el clima. Los datos actualizados 2013-2014 de la Organización para la Cooperación y el Desarrollo Económicos (OCDE), revelan que esta relación ha disminuido a 3,6 dólares de crédito por cada dólar donado. Sin embargo, persiste la omisión de los aportes de los países en desarrollo en las fuentes de información, con lo cual se desconoce la amplitud de la brecha en el financiamiento y quién está asumiendo la factura de la mitigación y adaptación del fenómeno. Este artículo examina los flujos financieros para el clima hacia la región, en el período 2010-2013,y los recursos para el mecanismo REDD+. Tiene por objetivo dibujar el modelo de gobernanza para el clima que prevalece en la región y enmarcarlo dentro del Acuerdo de París para establecer recomendaciones vis-à-vis el nuevo Protocolo
