In addition to structures, Almond and Powell showed that a political system consists of various functions, chief among them political socialization, recruitment and communication: socialization refers to the way in which societies pass along their values and beliefs to succeeding generations, and in political terms describe the process by which a society inculcates civic virtues, or the habits of effective citizenship; recruitment denotes the process by which a political system generates interest, engagement and participation from citizens; and communication refers to the way that a system promulgates its values and information.
