Surfing the web I found this page: es.coursera.org. It gives you many courses offered by the University of Michigan, but the only problem for English speakers is that all but one are in Spanish. They cover different careers and specialties. Here is a list of some that are offered.
Negociación exitosa: estrategias y habilidades esenciales (Successful negotiation: essential strategies and skills), in English at https://www.edx.org/course/successful-negotiation-essential-strategies-and-skills. We all negotiate daily. On a personal level, we negotiate with friends, family, owners, car dealers, and employers, among others. Negotiation is the key to business success. No business can survive without profitable contracts. Within a company, negotiation skills can lead to career advancement. That is why you should learn how to handle negotiations with this course.
Escribiendo en las ciencias (Writing in the sciences). This course teaches scientists to become more effective writers, using practical examples and exercises. Topics include principles of good writing, tricks for writing faster and with less anxiety, the format of a scientific manuscript, peer review, grant writing, ethical issues in scientific publications, and writing for general audiences.
Gestión de empresas de moda y lujo (Fashion and luxury business management) Learn how fashion and luxury companies work and understand their brands, products, retailers, and communication strategies. Travel through business models, international development, and product categories with influential industry experts.
Taking a case study approach, the course presents strategic brand management in luxury and fashion companies as a balancing act: tradition versus innovation, experience versus experimentation, casual versus elegant. All of these considerations work to increase brand value by fostering brand equity while remaining fresh, relevant, and contemporary in the global market.
