2. cocktail party 1 WHAT IS IT? ----------- This program models a cocktail party. The party is made up of groups of both men and women. The partygoers have a TOLERANCE that defines their comfort level with a group that has members of the opposite sex. If they are in a group that has a higher percentage of people of the opposite sex than their TOLERANCE allows, then they are considered "uncomfortable", and they leave that group to find another group. This action continues until everyone at the party is "comfortable" within their group. This model is based on the work of the pioneering economist Thomas Schelling. It is also described in: Resnick, M. & Wilensky, U. (1998). Diving into Complexity: Developing Probabilistic Decentralized Thinking through Role-Playing Activities.

3. HOW TO USE IT ------------- To set the number of people at the party, use the NUMBER slider. To set the number of initial groups, use the NUM-GROUPS slider. To set the tolerance of the people for the opposite sex, use the TOLERANCE slider. If the TOLERANCE slider is set to 75, then each person will tolerate being in a group with less than or equal to 75% people of the opposite sex. If there are more than this, the person is uncomfortable, and he/she leaves the group and tries out an adjacent group. The SETUP button sets up all the people into random groups. The GO button sets the party in motion. You can use the STEP-ONCE button to make all uncomfortable partygoers move once. The MOVES monitor shows the number of times people move from their groups. The NUMBER-HAPPY monitor shows how many people are content and this value is dynamically graphed in the "happy partygoers" plot. The counts are shown in gray for "single-sex" groups, white for mixed groups. The simulation ends when everyone is happy. The SINGLE-SEX-GROUPS monitor shows the number of single-sex groups and this value is dynamically plotted in the "single sex groups" plot. cocktail party 2 Master in economia e politica sanitaria - Simulazione per la sanità

4. RUNNING the MODEL ----------------- THINGS TO NOTICE ---------------- At the end of the simulation (when everyone is happy), notice the number of single-sex groups. Is there an increase from their initial compositions? Is there a critical tolerance at which each group ends up being a single-sex group? Notice the difference in time it takes for all groups to be comfortable depending upon the tolerance. THINGS TO TRY ------------- See how many mixed groups (not a single-sex group) you can get. Use the STEP-ONCE button, and experiment with different tolerances. Watch how one unhappy person can disrupt the stability of other groups. Is it possible to have an initial grouping such that the party is never completely content? (i.e. the model never terminates) Observe real parties. Is this model descriptive of real social settings? What tolerances would model the people in the real party? cocktail party 3 Master in economia e politica sanitaria - Simulazione per la sanità
