This course examines and presents processes of designing and implementing land readjustment in the context of developing countries.
Land readjustment is an alternative land-assembly approach to government compulsory purchase (often referred to as eminent domain) and voluntary market transaction. In the land readjustment process, a public or private agency invites property owners to become stakeholders in a redevelopment project and to contribute their lands to the project as investment capital. In return, each property owner receives a land site of at least equal value in the vicinity of the original site upon project completion. After all properties in the district are assembled, the combined land sites are subdivided to make space for wider roads and other local infrastructure.
The conventional approaches to land assembly are often conflict-ridden. Through this course, practitioners can add another viable option to their toolbox by learning about land readjustment as an alternative approach to urbanization in developing countries.
Land readjustment has been shown to reduce the initial capital requirement for land assembly, discourage holdouts, and minimize massive relocation of existing residents. When applying land readjustment at the right time and in the right place, this approach could mediate a major hindrance of land redevelopment in countries that are facing rapid urbanization.

Feeding nine billion people in 2050 without exhausting the planetary reserves is perhaps the greatest challenge mankind has ever faced. This environmental studies course will examine the principles of production ecology and the ‘availability pillar’ of global food security that lie at the heart of food production, which can be applied to both crops and animal production. This course will discuss why yields in some parts of the world are lagging behind and identify the agro-ecological drivers that shape the wide diversity of production systems.
Furthermore, key issues relating to the closing of yield gaps and the difference in visions of sustainability will be explored.
This online course will be of great interest to international students and those with varied educational backgrounds, both professionally and culturally, to enrich their views and action perspectives related to global food security and food systems. Professor Ken E. Giller will introduce learners to crop production and underlying bio-physical principles in order to identify constraining factors in yield formation. He will explain how to assess yield gaps at the level of fields and production systems around the world, contributing to efficient resource management. Wageningen University and Research, through its unique systems-based approach to food systems, adds the phase of primary production to the broad context of global food security.

Today, you are the law.
What does it mean to be a citizen? It means to participate in your society, to connect with others, and to decide, with them, the issues that you face.
It starts with you.
We need to learn to talk civilly with each other about the issues of consequence, but are we capable of learning how to speak together, listen together, and decide together?
In JuryX: Deliberations for Social Change, an experiment in online civic discourse, you are invited to engage with Professor Nesson and others with an understanding that each of us starts from a place of anonymity. Through a series of asynchronous and synchronous online group activities, you will explore a deliberative system by which emotionally charged issues can be discussed.
Although you will learn a bit about the history of jury and even serve as a member of a virtual jury for a mock criminal case, this experiment is about active participation in the deliberative process and how you might use that framework to facilitate dialogue within your own affinity group or community.
The program consists of six modules. Each week, you will learn and apply a new step in a system designed to foster meaningful dialogue. Starting with an introduction to the course’s deliberative framework, you will move from a traditional jury-based application to a live social issue unfolding in real time: the Massachusetts referendum for the “Legalization, Regulation, and Taxation of Marijuana.” As citizens of the Commonwealth of Massachusetts deliberate on this issue, so will you and your JuryX peers. What arguments will shape this debate, and what will the final outcome be?
Can we, civilly, discuss an issue like marijuana regulation?
Two synchronous small-group online deliberations will be held using Google Hangout. Participation is optional, but highly recommended.
JuryX: Deliberations for Social Change is, ultimately, about the most fundamental of human interactions: communication. By listening, speaking, persuading, and being persuaded, you will learn about yourself and others.
If you have faith, faith will be given to you.

Our lives are full of combinations. Combinatorial mathematics is just the science to deal with combinations of discrete items. As an ancient field, the history of combinatorial mathematics can be traced back over 4000 years to the age of the Great Yu in ancient China. Today, combinatorial mathematics is regarded as the basis of computer science since the algorithms in programming heavily rely on the analysis of the discrete elements.
Instead of relying on the traditional mathematical "theorem - proof" format, this course demonstrates various principles in an intuitive manner with ancient stories, the scenes of movies and even a magic show. What you’ll learn:
- The counting principles based on the basic operations “+”, “-”, “*”, “/”;
- Generating functions
- Recurrent number serials such as Fibonacci number, Catalan number, and more
- Pigeon hole principles
- Inclusion and exclusion principles
- Polya counting based on group theory
This course is based on a highly regarded on-campus Tsinghua class called Combinatorics, and is ideal for students who are interested in mathematics or computer science. Enroll today and learn the mathematical theory needed to solve the real-world problems!
