Criminology, scientific study of the non legal aspects of crime and delinquency, including its causes, correction, and prevention, from the view points of such diverse disciplines as anthropology, biology, psychology and psychiatry, economics, sociology, and statistics. Viewed from a legal perspective, the term crime refers to individual criminal actions (e.g., a burglary) and the societal response to those actions (e.g., a sentence of three years in prison). By comparison, the field of criminology incorporates and examines broader knowledge about crime and criminals. For example, criminologists have attempted to understand why some people are more or less likely to engage in criminal or delinquent behaviour. Criminologists have also examined and attempted to explain differences in crime rates and the criminal code between societies and changes in rates and laws over time. Many criminologists consider themselves to be neutral public policy experts, gathering facts for various governmental officials responsible for drawing policy conclusions. However, some criminologists—like their counterparts in such fields as the atomic and nuclear sciences—maintain that scientists must shoulder responsibility for the moral and political consequences of their research. Thus, some criminologists have actively campaigned against capital punishment and have advocated in favour of various legal reforms. Criminologists who oppose this activist role contend that the findings of criminological research must be weighed along with political, social, religious, and moral arguments, a task best left to political bodies. Not denying the right of criminologists to express their opinions as ordinary citizens and voters, this view nonetheless maintains that a government by popular will is less dangerous than a government by experts. In the last decades of the 20th century, criminology grew to encompass a number of specialized study areas. One of these was criminalistics, or scientific crime detection, which involves such measures as photography, toxicology, fingerprint study, and DNA evidence (see also DNA fingerprinting). It had previously been excluded from criminology because of its focus on particular criminal actions rather than on the broader knowledge about crime and criminals. Criminology further expanded its reach by devoting significant attention to victimology, or the study of the victims of crime, the relationships between victims and criminals, and the role of victims in the criminal events themselves. Criminal justice has also emerged as a separate but closely related academic field, focusing on the structure and functioning of criminal justice agencies—including the police, courts, corrections, and juvenile agencies—rather than on explanations of crime. (See juvenile justice.) The relationship of criminology to various other disciplines has resulted in considerable diversity in its academic placement within universities. Universities in Europe have tended to treat criminology as part of legal education, even in circumstances where its principal teachers were not lawyers. In the United Kingdom, for example, the Institute of Criminology is part of the law faculty of the University of Cambridge; in other schools criminological research and teaching have usually been divided between departments of sociology or social administration, law faculties, and institutes of psychiatry. In South America the anthropological and medical elements predominate, and in the United States, though there has been a trend toward housing criminology and criminal justice in separate multidisciplinary departments, criminology has most often been situated in departments of sociology. The information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
