El Dr. Dijkstra, profesor de petrología ígnea, afirmó: “Cada vez dependemos más de nuestros teléfonos móviles, pero ¿cuántos de nosotros pensamos realmente en lo que hay detrás de la pantalla? También hay elementos raros como el neodimio, el praseodimio, el gadolinio y el disprosio, por no hablar de las cantidades de oro, plata y otros elementos de gran valor. Todos ellos deben ser extraídos mediante la explotación de minerales de alto valor, lo que supone una importante presión para el planeta”.
Para llevar a cabo el experimento, los investigadores tomaron el teléfono mezclado y lo mezclaron a casi 500°C con un potente oxidante, el peróxido de sodio. A continuación, pudieron hacer un análisis detallado de la solución resultante en ácido para determinar su contenido químico exacto.Los resultados mostraron que el teléfono utilizado en las pruebas contenía 33g de hierro, 13g de silicio y 7g de cromo, así como cantidades menores de otras sustancias abundantes.Sin embargo, también presentaba una serie de elementos críticos como 900mg de tungsteno y 70mg de cobalto y molibdeno, así como 160mg de neodimio y 30mg de praseodimio. Y cada teléfono contenía 90 mg de plata y 36 mg de oro. Esto significa que, desde el punto de vista de la concentración, un teléfono tiene 100 veces más oro -o 10 veces más tungsteno- que un recurso mineral que los geólogos llamarían “de alta calidad”. También demuestra que para crear un solo teléfono habría que extraer entre 10 y 15 kg de mineral, incluidos 7 kg de mineral de oro de alta calidad, 1 kg de mineral de cobre típico, 750 g de mineral de tungsteno típico y 200 g de mineral de níquel típico.

CEU San Pablo University is committed to international projection by offering students the opportunity to complete and validate their education abroad through agreements established with schools and universities from all continents within the Erasmus+ Program of the European Commission or through Bilateral Exchange Agreements signed between CEU San Pablo University and other foreign universities.
CEU San Pablo University has an agreement with Audencia Business School (Nantes, France) offering an innovative and exclusive training project that includes a Bachelor’s Degree at CEU San Pablo + Master’s Degree in Nantes, France. Learning will be international, with a real and practical approach.
Audencia Business School is a “Grande École” located in the city of Nantes, capital of the Loire-Atlantique department in western France. Founded in 1900, it is considered one of the oldest business schools in the world and one of the most prestigious in Europe. It is also one of the top 10 business schools in France and its programs have the triple international accreditation of EQUIS, AACSB and AMBA.

The outcome of the 2016 referendum on Brexit may have come as a surprise, as the abrupt manner in which the United Kingdom finally effectively left the European Union on December 31, 2020, has undoubtedly come as a surprise. However, what we have seen is not so alien to the history of the British relationship with the rest of Europe. If we go back centuries, we can see a geopolitical pattern that has been repeated on other occasions, and also today, without having to speak of determinism.
Although it is worth mentioning some previous moments in the relationship of insular Britain with the continent next to it, such as the period of Romanization, the gestation of the pattern that at the same time combines linkage and distancing, or even rejection, can perhaps be placed at the beginning of the second millennium, when from Norman invasions that cross the English Channel the nascent kingdom of England is consolidated precisely against the power of the other shore.

Introduction. Social trust has long attracted the interest of researchers from different disciplines. Most studies on this subject have been based on single-country data, and have considered only one dimension of social trust at a time (e.g., trust in science, in the media, or in political institutions). This research develops the model proposed by the Global Trust Inventory (GTI) by simultaneously analyzing several dimensions of social trust, as well as examining how trust in institutions varies across societies. Based on an online panel survey distributed across 22 countries (N = 22,033), we study differences in social trust across societies, including trust in government, government agencies, national security institutions and producers of scientific knowledge in our analysis. In addition, the study contributes to a broader operationalization of the concept of social trust by introducing a measure of trust in the media. The results are discussed based on the comparison between emerging and developed countries, according to their Human Development Index (HDI).
