[17] Customarily, a classification scheme is utilized that places poisons in categories such as: corrosive agents, gases and volatile agents, metallic poisons, non-volatile organic agents, and ...
Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. [1] Specialists in this field have a wide array of methods and instruments to help identify unknown substances.
Marsh performed the standard test by mixing a suspected sample with hydrogen sulfide and hydrochloric acid. While he was able to detect arsenic as yellow arsenic trisulfide, when it was shown to the jury it had deteriorated, allowing the suspect to be acquitted due to reasonable doubt. [39] Annoyed by that, Marsh developed a much better test.
The study was based on 33,005 multiple-choice responses and 1760 short text responses, by 75 practicing bloodstain pattern analysts on 192 bloodstain patterns selected to be representative of casework, [9] and stated: Our results show that conclusions were often erroneous and often contradicted other analysts.
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
[1] [2] [3] General strain theory has gained a significant amount of academic attention since being developed in 1992. [4] Robert Agnew's general strain theory is considered to be a solid theory, has accumulated a significant amount of empirical evidence, and has also expanded its primary scope by offering explanations of phenomena outside of ...
Biosocial criminology is an interdisciplinary field that aims to explain crime and antisocial behavior by exploring biocultural factors. While contemporary criminology has been dominated by sociological theories, biosocial criminology also recognizes the potential contributions of fields such as behavioral genetics, neuropsychology, and evolutionary psychology.
The theory has been extensively applied and has become one of the most cited theories in criminology. Unlike criminological theories of criminality, routine activity theory studies crime as an event, closely relates crime to its environment and emphasizes its ecological process, [ 2 ] thereby diverting academic attention away from mere offenders.
