Consumption of Scientific Information on Television and Internet

This paper consists of a brief overview of studies related to the consumption of scientific information both on television and on the Internet by the general public, as well as by young people in particular. The preferences of the Internet are clear nowadays, even though television continues to have a place in multiple media. Particular cases are presented to follow a line over time and observe how the consumption of scientific information has been transforming, and how television has adapted to the new forms of production, dissemination, and consumption brought about by innovations, specifically information and communication technologies

¿Identifican la información científica los estudiantes universitarios? Acercamiento a sus “vistazos” en los medios de comunicación

El objetivo principal de este trabajo consistió en indagar acerca de dónde se nutrían los alumnos universitarios cuando requerían información científica y cuáles eran los motivos para dichas elecciones; es un primer acercamiento, fundamentado conceptualmente en el marco de “la sociedad del conocimiento”. Participaron 234 estudiantes de pregrado de la Universidad de Guadalajara quienes contestaron un cuestionario de opciones múltiples y preguntas abiertas. Los alumnos refieren que la Internet es su medio preferido por diferentes razones, entre ellas, porque está más a la mano, es rápida y de fácil acceso. No obstante, reconocen que son los docentes en quienes mayormente confían. De cualquier manera, estos primeros resultados dan pie para abrir mayores interrogantes y cuestionar hasta qué grado los docentes siguen siendo pieza clave en el manejo de información sin ser desplazados completamente por las nuevas tecnologías de la información y la comunicación (TIC)

The Social Implications of Covid-19 for Nursing Students

Given that the pandemic generated by COVID-19 has caused much unforeseen havoc, this paper shows how higher education students of a nursing degree program at the University of Guadalajara, Mexico, socially confronted this virus, with an approach to their feelings, attitudes, opinions and experiences during the confinement and the actions lived by them. To answer the question, an online questionnaire of mostly open-ended questions was used, which was analyzed through the technique of thematic content analysis. The findings show social representations that, although very local, were very similar to those found in other parts of the world (sadness, fear, anger, confusion, etc.), which is not too surprising given the vertiginous fluidity of the traditional and virtual media

Delving into country risk

Since the Latin American debt crisis of the early 80s, country risk analysis has accounted for a significant part of the work of research and risk management departments of banks, insurance companies, rating agencies, financial market regulators, and multinational companies. Country risk is a very broad concept, that includes sovereign risk, transfer risk, and other risks related with international financial activities. Country risk analysis requires delving into multiple fields, such as economics, finance, politics and history. This paper addresses the concept of country risk, the agents involved, the methods for assessing country risk, the payments crises, risk prevention, the assessment of country risk in the present world and the Spanish country risk regulatio

Actitudes lingüísticas en el portugués uruguayo: marcas de una identidad

IX Congresso Brasileiro de Hispanistas realizado nos dias 22 a 25 agosto 2016El contacto lingüístico entre el español (E) y el portugués brasileño (PB) en la región fronteriza BrasilUruguay ha producido una variedad conocida popularmente como “portuñol” o portugués uruguayo (PU). Estas variedades han estado disputando un espacio en la comunidad fronteriza, conformándose así una situación de bilingüismo y diglosia. La política lingüística del Uruguay preocupada en fortalecer el idioma nacional ante el avance del portugués, decretó la obligatoriedad de la enseñanza del E con la Ley de Educación Común (1877) y prohibió el uso del portugués (P) en las escuelas fronterizas. Esta ley prevaleció por muchos años e hizo que sea lo que es hoy, una lengua híbrida y estigmatizada en la comunidad, aunque actualmente ya se escuchan muchas voces que la defienden. Como vemos, la disputa continua ha dejado marcas profundas en la identidad de sus hablantes. En esta comunicación presentamos algunos resultados de la investigación que estamos realizando sobre las actitudes lingüísticas de los hablantes del PU acerca de su variedad. Asociando algunos presupuestos de la sociolingüística (CALVET, 2002; BAGNO, 2002), de la política lingüística (BARRIOS,2008; CARVALHO, 2007) y de los estudios culturales (HALL, 2005), analizamos una muestra de lengua oral (37 informantes), recogida en la ciudad de Rivera, lo siguiente: (1) cuáles son las consecuencias sociales que derivan de la situación de contacto, tales como actitudes, conflictos y prejuicios lingüísticos; (2) cómo los hablantes del PU construyen su identidad cultural híbrida? y, (3) cuál ha sido el rol de las políticas lingüísticas sobre la situación del portugués en el Uruguay?UNILA­-UNIOEST

On rooted directed path graphs

An asteroidal triple is a stable set of three vertices such that each pair is connected by a path avoiding the neighborhood of the third vertex. An asteroidal quadruple is a stable set of four vertices such that any three of them is an asteroidal triple. Two non adjacent vertices are linked by a special connection if either they have a common neighbor or they are the endpoints of two vertex-disjoint chordless paths satisfying certain technical conditions. Cameron, Ho`ang, and L´evˆeque [DIMAP Workshop on Algorithmic Graph Theory, 67–74, Electron. Notes Discrete Math., 32, Elsevier, 2009] proved that if a pair of non adjacent vertices are linked by a special connection then in any directed path model T the subpaths of T corresponding to the vertices forming the special connection have to overlap and they force T to be completely directed in one direction between these vertices. Special connections along with the concept of asteroidal quadruple play an important role to study rooted directed path graphs, which are the intersection graphs of directed paths in a rooted directed tree. In this work we define other special connections; these special connections along with the ones defined by Cameron, Ho`ang, and L´evˆeque are nine in total, and we prove that every one forces T to be completely directed in one direction between these vertices. Also, we give a characterization of rooted directed path graphs whose rooted models cannot be rooted on a bold maximal clique. As a by-product of our result, we build new forbidden induced subgraphs for rooted directed path graphs.Facultad de Ciencias ExactasConsejo Nacional de Investigaciones Científicas y Técnica

End simplicial vertices in path graphs

A graph is a path graph if there is a tree, called UV-model, whose vertices are the maximal cliques of the graph and for each vertex x of the graph the set of maximal cliques that contains it induces a path in the tree. A graph is an interval graph if there is a UV-model that is a path, called an interval model. Gimbel [3] characterized those vertices in interval graphs for which there is some interval model where the interval corresponding to those vertices is an end interval. In this work, we give a characterization of those simplicial vertices x in path graphs for which there is some t/V-model where the maximal clique containing x is a leaf in this UV-model.Facultad de Ciencias Exacta
