Learner Testimonial

“This course is like a dream coming true...as kid (10 - 12 years) I was already building circuits and reading books about Digital Circuits. Due to all kind of circumstances I never got to pursue a study and career in electronics ...now I am almost 50... I see this as a second chance. Thank you very very much for this awesome course. One of the best, (if not the best) MOOCs I've ever taken.” -- Previous Student

The human mind is an evolutionary product, just like the body. However, the mind does not remain in fossil form like bones and teeth. Therefore, to better study and understand our minds their evolutionary origins we need to compare our cognitive features with those of different living primates. This approach is called "Comparative Cognitive Science (CCS)". CCS is a unique combination of Psychology and Primatology. CCS tries to give answers to the fundamental questions such as "what is uniquely human?", "where did it come from?”, "how did we get here?”, and "where do we go?" This intensive course focuses on chimpanzees, the closest relatives of humans.

This course covers selected areas of current research on CCS. We focus on behavioral studies of nonhuman animals, especially chimpanzees. Since the chimpanzee and the human share the latest common ancestor, only about five million years ago, this great ape provides the key to understanding our nature.

¿Qué es envejecer? ¿Qué es más importante a la hora de envejecer, la herencia o el ambiente? ¿Podemos actuar sobre nuestro propio envejecimiento? ¿Qué tendríamos que hacer para envejecer bien?

Estas y otras muchas preguntas serán respondidas a los largo de este MOOC en el que se pretende transmitir conocimientos actualizados y científicos sobre cómo llegar a una longevidad positiva y saludable a la vez que se pretende motivar a los participantes en la puesta en práctica de una serie de comportamientos que conforman lo que llamamos estilos de vida activos y saludables. Así pues, esos conocimientos no serán suficientes para el cambio hacia un envejecimiento activo; ello dependerá de que cada uno de los participantes incorpore, como hábitos, esos comportamientos que sabemos influyen en un envejecimiento óptimo, lo cual requerirá de una actitud positiva y de la determinación, el querer realizar algunos cambios.

Partimos de la consideración de que el envejecimiento no tiene un claro inicio sino que “vivir es envejecer y envejecer es vivir” y consideramos que a todo lo largo de la vida hay crecimiento, estabilidad y declive. Desde luego, huimos de una visión simplista, exclusivamente positiva, del envejecimiento y dado que la edad está asociada a la enfermedad, la discapacidad y a otros problemas, tratamos de promover ciertas “soluciones” que llevan consigo lo siguiente: optimizar las capacidades físicas, mentales, afectivas y sociales; prevenir potenciales enfermedades y problemas y, en su caso, compensar o paliar existentes déficits.

Esas estrategias, soluciones comportamentales y estilos de vida protectores o combativos de factores de riesgo pertenecen a cuatro dominios esenciales: la mejora de la salud y la funcionalidad; promover el ejercicio físico y cognitivo regular; el mantenimiento y la optimización del afecto positivo y el control y, finalmente, la implicación familiar y social.

Este curso está dirigido a personas de cualquier edad que estén interesadas en envejecer bien. Va a requerir no solo el aprendizaje de conocimientos científicos sino una implicación personal de los participantes puesto que pretendemos, también, la introducción de cambios en la forma de percibir la vejez y en la incorporación de hábitos saludables que lleven consigo, a largo plazo, el desarrollo personal y la satisfacción con la vida.

In this economics course, you will learn some of the major concepts of macroeconomics, such as gross domestic product, price level, inflation, unemployment, economic growth and the balance of payments.

You will see that macroeconomics is not that different from microeconomics, in that the interaction of supply and demand provides the basic organizing framework for analyzing the workings of a national economy. You will learn how the equilibrium levels of national income and prices are determined at the intersection of aggregate supply and aggregate demand curves, just as the equilibrium quantity of transaction and price of an individual commodity is determined at the intersection of supply and demand curves.

This is an introductory course at the most elementary level so no prior knowledge of economics is required.

Designing effective interactive systems requires understanding the needs and capabilities of the people who will be using them.
