FBI Method Of Profiling
The FBI method of profiling is a system created by the Federal Bureau of Investigation (FBI) used to detect and classify the major personality and behavioral characteristics of an individual based upon analysis of the crime or crimes the person committed. One of the first American profilers was FBI agent John E. Douglas, who was also instrumental in developing the behavioral science method of law enforcement. Profiling phases The process this approach uses to determine offender characteristics involves: #An assimilation phase where all information available in regard to the crime scene, victim, and witnesses is examined. This may include photographs of the crime scene, autopsy reports, victim profiles, police reports, and witness statements. #The "classification stage", which involves integrating the information collected into a framework which essentially classifies the murderer as "organized" or "disorganized". Organized murderers are thought to have advanced social skills, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Bureau Of Investigation
The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States and its principal federal law enforcement agency. Operating under the jurisdiction of the United States Department of Justice, the FBI is also a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A leading U.S. counterterrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes. Although many of the FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and NCA; the New Zealand GCSB and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection abroad, the FBI is primarily a domestic agency, maintaining 56 field offices in major cities t ...

Inter-rater Reliability
In statistics, inter-rater reliability (also called by various similar names, such as inter-rater agreement, inter-rater concordance, inter-observer reliability, inter-coder reliability, and so on) is the degree of agreement among independent observers who rate, code, or assess the same phenomenon. Assessment tools that rely on ratings must exhibit good inter-rater reliability, otherwise they are not valid tests. There are a number of statistics that can be used to determine inter-rater reliability. Different statistics are appropriate for different types of measurement. Some options are joint-probability of agreement, such as Cohen's kappa, Scott's pi and Fleiss' kappa; or inter-rater correlation, concordance correlation coefficient, intra-class correlation, and Krippendorff's alpha. Concept There are several operational definitions of "inter-rater reliability," reflecting different viewpoints about what is a reliable agreement between raters. There are three operational de ...

Investigative Psychology
In applied psychology, investigative psychology attempts to describe the actions of offenders and develop an understanding of crime. This understanding can then help solve crimes and contribute to prosecution and defense procedures. It brings together issues in the retrieval of investigative information, the drawing of inferences about that information and the ways in which police decision making can be supported through various systems derived from scientific research. It should not be confused with profiling which grew out of the experience of police officers offering opinions to their colleagues about the possible characteristics of unknown offenders. Overview Investigative Psychology grows directly out of empirical research and logical inference to cover the full range of investigative activities not only the preparation of 'profiles'. The inference processes at the heart of Investigative Psychology contrast with the approach used in the Federal Bureau of Investigation whi ...

Offender Profiling
Offender profiling, also known as criminal profiling, is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator. Multiple crimes may be linked to a specific offender and the profile may be used to predict the identified offender's future actions. In the 1980s, most researchers believed offender profiling was relevant only to sex crimes, like serial rape or sexual homicide, but since the late 1990s research has been published to support its application to arson (1998), and then later terrorism (2000) and burglary (2017). Theory Psychological profiling is described as a method of suspect identification which seeks to identify a person's mental, emotional, and personality characteristics based on things done or left at the crime scene. There are two major assumptions made when it comes to offender profiling: behavioral consistency and homology. Be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forensic Psychology
Forensic psychology is the development and application of scientific knowledge and methods to help answer legal questions arising in criminal, civil, contractual, or other judicial proceedings. Forensic psychology includes both research on various psychology-law topics, such as jury selection, reducing systemic racism in criminal law, and eyewitness testimony, as well as professional practice, such as evaluating individuals to determine competency to stand trial or assessing military veterans for service-connected disability compensation. The field traces its roots to contributions by Wilhem Wundt, Hugo Münsterberg, and Sigmund Freud among others. Contemporary definitions of forensic psychology recognize that several subfields of psychology apply "the scientific, technical, or specialized knowledge of psychology to the law." The American Psychological Association's ''Specialty Guidelines for Forensic Psychologists'' reference several psychology subdisciplines, such as social, ...

Smallest-space Analysis
Multidimensional scaling (MDS) is a means of visualizing the level of similarity of individual cases of a dataset. MDS is used to translate "information about the pairwise 'distances' among a set of n objects or individuals" into a configuration of n points mapped into an abstract Cartesian space. More technically, MDS refers to a set of related ordination techniques used in information visualization, in particular to display the information contained in a distance matrix. It is a form of non-linear dimensionality reduction. Given a distance matrix with the distances between each pair of objects in a set, and a chosen number of dimensions, ''N'', an MDS algorithm places each object into ''N''-dimensional space (a lower-dimensional representation) such that the between-object distances are preserved as well as possible. For ''N'' = 1, 2, and 3, the resulting points can be visualized on a scatter plot. Core theoretical contributions to MDS were made by James O. Ramsay of M ...

Empirical Validation
Empirical evidence for a proposition is evidence, i.e. what supports or counters this proposition, that is constituted by or accessible to sense experience or experimental procedure. Empirical evidence is of central importance to the sciences and plays a role in various other fields, like epistemology and law. There is no general agreement on how the terms ''evidence'' and ''empirical'' are to be defined. Often different fields work with quite different conceptions. In epistemology, evidence is what Justification (epistemology), justifies beliefs or what determines whether holding a certain belief is rational. This is only possible if the evidence is possessed by the person, which has prompted various epistemologists to conceive evidence as private mental states like experiences or other beliefs. In philosophy of science, on the other hand, evidence is understood as that which ''Scientific method#Confirmation, confirms'' or ''disconfirms'' Hypothesis#Scientific hypothesis, scienti ...

Ad Hoc
Ad hoc is a Latin phrase meaning literally 'to this'. In English, it typically signifies a solution for a specific purpose, problem, or task rather than a generalized solution adaptable to collateral instances. (Compare with '' a priori''.) Common examples are ad hoc committees and commissions created at the national or international level for a specific task. In other fields, the term could refer to, for example, a military unit created under special circumstances (see '' task force''), a handcrafted network protocol (e.g., ad hoc network), a temporary banding together of geographically-linked franchise locations (of a given national brand) to issue advertising coupons, or a purpose-specific equation. Ad hoc can also be an adjective describing the temporary, provisional, or improvised methods to deal with a particular problem, the tendency of which has given rise to the noun ''adhocism''.
