Graphology
Forensics and DNA: Graphology
Graphology entails the study of an individual's handwriting as theory or practice when it comes to inferring an individual's character, attitudes, disposition from their handwriting, graphology is generally termed a pseudoscience .this term is at times incorrectly used in reference to forensic document examination. Graphology has been marred with a lot of controversy for over a century. Supporters of graphology point out the anecdotal evidence of very many positive testimonies as the reason as to why it is used for evaluation of personality, most of the empirical studies has failed to show how valid the claims made by these supporters are. Handwriting analysis is a very tedious and methodical process which is based and relies on extensive knowledge of how people use letters, which characteristics of the letter formations are unique and the psychological process behind the specific handwriting. Ways through which an individual's fine motor skills affect an individual's handwriting and leave a clue on the identity of an author.
The primary basis of graphology as a science is the fact that everyone in the world has their own unique way of writing. When we were children in primary school, we learned writing based on a specific copy book that contains a style of writing so at first we probably all wrote in the same way as children of our age and location. With time, the writing characteristics learned in school, the specific style characteristics became an underlying method of the way we write. Therefore people developed individual characteristic that are unique and distinguish ones own handwriting from...
At the time that Byrd was tried in 1985 DNA technology was not capable of forensic analysis of biological evidence however; in 1997 a comparison was conducted of Byrd's DNA with the bodily fluid in the rape kit that had been collected at the time of the incident resulting in Byrd's exoneration for this crime. The importance of proper preservation of biological evidence is highlighted in this case and
Forensic Pathology: Forensics and DNA DNA is part of the building blocks of human life and individuality: "DNA is present in nearly every cell of our bodies, and we leave cells behind everywhere we go without even realizing it. Flakes of skin, drops of blood, hair, and saliva all contain DNA that can be used to identify us" (Norrgard, 2008). DNA has long been a major part of forensics testing used
" The true significance of a strand of DNA is that it is sure to house all of the necessary information that is the blueprint or code for various aspect of the body that it represents. Consider that in the majority of organisms, genetics is established by the breeding of pairs of parents which results in an off-spring that has a combination of each of the parents' genetic codes. "Despite the
Forensic Chemistry Forensics is a very important part of a crime scene investigation. There used to be a time when murders or crimes were left unsolved due to the lack of evidence. However with the advances in technology and research in forensics, crime solving has become a lot easier. The branch of science, which helps out in finding out important evidence, is known as Forensics Chemistry. Forensics Chemistry employs methods, which
, 2007, p. 153). Conclusion The research showed that DNA evidence can be a valuable tool for the criminal justice system, but the effectiveness of such evidence depends on a number of factors. Among the more salient of these factors was the need to ensure that the DNA sample is collected and stored properly, and that it is transported to a testing facility in a timely and appropriate fashion. Other issues that
Forensic Science and Police Work Forensic science has been playing a very crucial role in crime-solving activities of the investigative agencies for last many years. Its popularity has grown tremendously even though it cannot be trusted to formally indict someone. This is because while forensic evidence is considered important, there are certain specific problems attached with it, which can significantly limit the credibility of the results obtained from forensic examination. Forensic evidence
