Social networkA social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics.
State crimeState crimes are crimes committed on behalf of or with the connivance of governments. The investigation and prosecution of such crimes is made more difficult by a number of circumstances. In criminology, state crime is activity or failures to acts that break the state's own criminal law or public international law. For these purposes, Ross (2000b) defines a "state" as the elected and appointed officials, the bureaucracy, and the institutions, bodies and organizations comprising the apparatus of the government.
Public-order crimeIn criminology, public-order crime is defined by Siegel (2004) as "crime which involves acts that interfere with the operations of society and the ability of people to function efficiently", i.e., it is behaviour that has been labelled criminal because it is contrary to shared norms, social values, and customs. Robertson (1989:123) maintains a crime is nothing more than "an act that contravenes a law". Generally speaking, deviancy is criminalized when it is too disruptive and has proved uncontrollable through informal sanctions.
Rational choice theory (criminology)In criminology, rational choice theory adopts a utilitarian belief that humans are reasoning actors who weigh means and ends, costs and benefits, in order to make a rational choice. This method was designed by Cornish and Clarke to assist in thinking about situational crime prevention. The rational choice theory has sprung from older and more experimental collections of hypotheses surrounding what has been essentially, the empirical findings from many scientific investigations into the workings of human nature.
Broken windows theoryIn criminology, the broken windows theory states that visible signs of crime, anti-social behavior and civil disorder create an urban environment that encourages further crime and disorder, including serious crimes. The theory suggests that policing methods that target minor crimes such as vandalism, loitering, public drinking, jaywalking, and fare evasion help to create an atmosphere of order and lawfulness. The theory was introduced in a 1982 article by social scientists James Q. Wilson and George L. Kelling.
Criminal psychologyCriminal psychology, also referred to as criminological psychology, is the study of the views, thoughts, intentions, actions and reactions of criminals and suspects. It is a subfield of criminology and applied psychology. Criminal psychologists have many roles within legal courts, including being called upon as expert witnesses and performing psychological assessments on victims and those who have engaged in criminal behavior.
Anthropological criminologyAnthropological criminology (sometimes referred to as criminal anthropology, literally a combination of the study of the human species and the study of criminals) is a field of offender profiling, based on perceived links between the nature of a crime and the personality or physical appearance of the offender. Although similar to physiognomy and phrenology, the term "criminal anthropology" is generally reserved for the works of the Italian school of criminology of the late 19th century (Cesare Lombroso, Enrico Ferri, Raffaele Garofalo and Lorenzo Tenchini).
Social disorganization theoryIn sociology, the social disorganization theory is a theory developed by the Chicago School, related to ecological theories. The theory directly links crime rates to neighbourhood ecological characteristics; a core principle of social disorganization theory that states location matters. In other words, a person's residential location is a substantial factor shaping the likelihood that that person will become involved in illegal activities.
Public criminologyPublic criminology is an approach to criminology that disseminates criminological research beyond academia to broader audiences, such as criminal justice practitioners and the general public. Public criminology is closely tied with “public sociology”, and draws on a long line of intellectuals engaging in public interventions related to crime and justice. Some forms of public criminology are conducted through methods such as classroom education, academic conferences, public lectures, “news-making criminology”, government hearings, newspapers, radio and television broadcasting and press releases.
Political crimeIn criminology, a political crime or political offence is an offence involving overt acts or omissions (where there is a duty to act), which prejudice the interests of the state, its government, or the political system. It is to be distinguished from state crime, in which it is the states that break both their own criminal laws or public international law. States will define as political crimes any behaviour perceived as a threat, real or imagined, to the state's survival, including both violent and non-violent oppositional crimes.
