1964 film directed by Pier Paolo Pasolini

本书通过缜密的逻辑演绎，将先前的国际关系学中散乱的术语整合到统一的理论框架中，广泛借鉴了其他学科（包括科学哲学、社会学、微观经济学）的理论成果。在书中，作者从排列原则、单元功能和权力分配三个角度界定了国际政治结构，认为结构是系统中的一系列约束条件，通过奖励一些行为、惩罚另一些行为而限制了国家的行为。

Unemployed Antonio is elated when he finally finds work hanging posters around war-torn Rome. However on his first day, his bicycle—essential to his work—gets stolen. His job is doomed unless he can find the thief. With the help of his son, Antonio combs the city, becoming desperate for justice.
