Food plays a central role in our society but few people actually understand what it does to our bodies. Learn more about nutrition and how our diet  profoundly impacts our current and future health. The course will focus on undernutrition and micronutrients. The team of Professors from Wageningen University will introduce you to vitamins and minerals and their role in human health.

The course will address the micronutrient content of foods and will cover the role of the various micronutrients in the body.  In addition, NUTR102x will discuss how suboptimal nutrition may affect human health and will pay particular attention to global hunger and malnutrition.

No previous knowledge needed but course adds to knowledge from NUTR101x. Join us to learn more about nutrition and health.

NUTR102x is part of the Nutrition-Food for Health xSeries of Wageningen University.

Humanity faces an immense challenge: providing abundant energy to everyone without wrecking the planet. If we want a high-energy future while protecting the natural world for our children, we must consider the environmental consequences of energy production and use. But money matters too: energy solutions that ignore economic costs are not realistic—particularly in a world where billions of people currently can’t afford access to basic energy services. How can we proceed?

Energy Within Environmental Constraints won’t give you the answer. Instead, we will teach you how to ask the right questions and estimate the consequences of different choices.

This course is intended for a diverse audience. Whether you are a student, an activist, a policymaker, a business owner, or a concerned citizen, this course will help you start to think carefully about our current energy system and how we can improve its environmental performance.

This course:

• Covers engineering, environmental science, and economics to enable critical, quantitative thinking about our energy system
• Focuses on a working understanding of energy technologies, rich in details of real devices and light on theory; you won’t find any electrodynamics here but will find enough about modern commercial solar panels to estimate if they would be profitable to install in a given location
• Covers environmental impacts of the energy system, focusing on air pollution, climate change, and land use
• Emphasizes costs: the cascade of capital and operating costs from energy extraction all the way through end uses
• Emphasizes quantitative comparisons and tradeoffs: how much more expensive is electricity from solar panels than from coal plants, and how much pollution does it prevent?  Is solar power as cost-effective an environmental investment as nuclear power or energy efficiency?  And how do we include considerations other than cost?

Please note that this is an abridged course, equivalent to roughly half of a full semester-long undergraduate course.  See the syllabus for topics that we include and a list of some we exclude.

This course provides a practical overview for selecting, implementing, and evaluating educational technology initiatives.

Schools are recognizing the potential for technology to transform teaching and learning. However, bringing technology into the classroom in a productive way is easier said than done. How do educators and others decide what kind and type of educational technology to use in the classroom? Which stakeholders influence that decision? What factors determine the success or failure of educational technology initiatives? How do we determine if these implementations are successful? 

This course provides a practical overview for selecting, integrating, implementing, and evaluating educational technology initiatives in formal educational settings, primarily in the US. It will include the perspectives of stakeholders that make such initiatives possible, and consider how to evaluate for efficacy. The audience for this course includes current and future teachers, entrepreneurs, developers, practitioners, and leaders in educational technology. 

Through four units over seven weeks, participants will develop an awareness and understanding of the “ecosystem” surrounding the implementation of educational technology in a formal educational setting. Participants will work towards creating a final project that synthesizes the main ideas from the course. 

Comment les humains s’organisent-ils en sociétés ? Qu’appelle-t-on « familles » et comment se constituent-elles ? Quel regard et quels types d’analyse l’anthropologie propose-t-elle sur les systèmes de parenté, symboliques, politiques, religieux ?

L’anthropologie prospective nous aide à comprendre et à anticiper les phénomènes qui transforment nos modes de vie contemporains. Elle pose un regard transversal sur les actions, les pratiques et les dires des personnes avec lesquelles travaillent les chercheurs.

« Entrer en anthropologie », c’est accepter de changer son regard sur le monde et de se décentrer par rapport à ses habitudes. Si vous désirez comprendre un peu mieux le monde et ses changements contemporains, suivez ces chercheurs sur leur terrain et expérimentez d’autres repères culturels.

Durant ces quelques heures, vous serez amenés à débattre avec des professeurs et des étudiants autour de questions sur la famille, les migrations, les mondes virtuels ou encore les mondes des invisibles. Vous apprendrez les bases de l'approche anthropologique et ce qu'elle peut vous apporter en termes de réflexion sur votre propre société, sur votre vie et votre quotidienneté. Ce cours vous donne l’opportunité de comparer vos expériences et d’échanger vos points de vue avec des personnes d’autres horizons.

Les six semaines de cours aborderont une série de thématiques illustrées par des exemples concrets de modes d’existence divers et disséminés sur le globe. Des enseignants plongés au cœur des pratiques sociales et des enjeux politiques et économiques les plus variés partageront avec vous leur expérience après des années d'immersion sur les terrains de recherche qui les passionnent.

Si vous êtes curieux de tout et que comprendre votre propre société mais aussi des sociétés méconnues vous intéresse, ce cours s'adresse à vous !

How do human beings organize themselves in societies? What do we call “families” and how do they form? What type of analysis does anthropology propose about parenthood, and symbolic, political and religious systems?

Prospective anthropology helps us to understand and anticipate phenomena that transform our ways of life today. It gives a cross-cutting look at the actions, practices, and words of those people with whom anthropological researchers work.

To understand anthropology is to accept changing your view of the world, and to shift your perpsective of your own habits. If you want to understand the world and its contemporary changes more deeply, follow these researchers in their field, and experiment with other cultural references.

In this course, you will debate with professors and students about family, migrations, virtual worlds, and the world of « invisibles. » You will learn the basis of the anthropological approach and what it can bring you as a reflection tool about your own society and your everyday life. This course gives you the opportunity to compare your experiences and to exchange points of view with people from all around the world.

Professors immersed in the heart of various social practices, political and economic issues will share their experiences with you after years of research in fields that they are passionate about.

If you are curious about everything, and if you are interested in understanding your own society but also unknown societies, this course is for you!

The business landscape is changing so rapidly that traditional management, business and computing courses do not meet the needs for the next generation of workers in the business world. Most traditional methods are of a repetitive, rule-based nature and will be gradually replaced by Artificial Intelligence. In the knowledge era, the most value added job will be to manage knowledge, which includes how knowledge is created, mined, processed, shared and reused in different trades and industry. At the same time, the amount of data and information (prerequisites of knowledge) is exploding exponentially. By 2020, IDC projects that the size of the digital universe will reach 40 zetabytes from all sources including, websites, weblog, sensors, and social media. Big data will transform how we live, work and even think. These trends and more will have a profound effect on how we see the world and create policies. In this course, the following topics are covered:

• What is knowledge management?
• How is knowledge captured, elicited, organized and created in business?
• What is big data and how can we use data analytics from a laymen perspective?
• What is Open Linked Data and how can it support machine reasoning?
• What defines the era of Science 2.0?
• How can new knowledge be mined from big data?
• What are the technical and social problems with big data?
• What is cloud computing and cloud services?
• What are examples of applications and case studies?
