Problem: In economics, the social science that studies the production, distribution, and consumption of goods and services, emotions are analyzed in some sub-fields of microeconomics, in order to assess the role of emotions on purchase decision-making and risk perception. In criminology, a social science approach to the study of crime, scholars often draw on behavioral sciences, sociology, and psychology; emotions are examined in criminology issues such as anomie theory and studies of "toughness," aggressive behavior, and hooliganism. In law, which underpins civil obedience, politics, economics and society, evidence about people's emotions is often raised in tort law claims for compensation and in criminal law prosecutions against alleged lawbreakers (as evidence of the defendant's state of mind during trials, sentencing, and parole hearings). In political science, emotions are examined in a number of sub-fields, such as the analysis of voter decision-making.
Along with sociology and behavioral sciences, what discipline informs the field of criminology?

Problem: In 1934 the Zagreb Provincial Committee sent Tito to Vienna where all the Central Committee of the Communist Party of Yugoslavia had sought refuge. He was appointed to the Committee and started to appoint allies to him, among them Edvard Kardelj, Milovan Đilas, Aleksandar Ranković and Boris Kidrič. In 1935, Tito travelled to the Soviet Union, working for a year in the Balkans section of Comintern. He was a member of the Soviet Communist Party and the Soviet secret police (NKVD). Tito was also involved in recruiting for the Dimitrov Battalion, a group of volunteers serving in the Spanish Civil War. In 1936, the Comintern sent "Comrade Walter" (i.e. Tito) back to Yugoslavia to purge the Communist Party there. In 1937, Stalin had the Secretary-General of the CPY, Milan Gorkić, murdered in Moscow. Subsequently Tito was appointed Secretary-General of the still-outlawed CPY.
