Colorism is the preferential treatment of people with light skin and discrimination against people with dark skin (Russell et al 2013).The red police-agents (c-police) represent police officers whose policing decisions are influenced by colorism.The NPL (Non Performing Loan) market is simulated in relation to the out-of-court behavior of borrowers: out-of-court behavior is helpful because it shortens the time of recovery even if the amount of the receivable decreases.

This model illustrates Kenneth Waltz's 1981 theory of nuclear proliferation.

According to Waltz, on a long enough timeline states will seek to balance against nuclear-armed states by acquiring their own nuclear weapons.

The model, associated files, and examples of data output files are included in the folder This is a model of viral infection dynamics and antiviral immunity.

The model considers infectivity and spread of visions in a tissue as well as cytotoxic host defense from T cells and NK cells as well as innate type I IFN based antiviral responses.

This is for educational purposes, but future versions of this model will explore several other variables dealing with proliferation/non-proliferation/disarmament.

This model simulates the phenomenon random genetic drift.We encourage users to share your models with the Net Logo user community. Roland Zink ([email protected])This model simulates the trucks' flow in tolls on a high way.You may upload your model through our model upload page. Use it if you prefer to host your model on an external web site. Credits: TUTORIAL DE NETLOGO - is a second version of the Local Policing and Colorism model which simulates the uni-directional influence (infection) of colorism.The web site will automatically create a web page for your model. In this version of the model, the influence of colorism is bi-directional.The model simulates the policing behavior of two types of local-level police-agents based on the phenomena of colorism.The industry has a tendency to sell products in low quantity, with high demand variation.
