What is involved in the profession of forensic scientist?
It very much depends on what area of forensic science you're concerned with, there are many branches of the profession in which you can proceed in. For example, here are a few of the most known forensic science professions:
Forensic Pathologists : Perform autotopsies, and overall examines the organs, tissue, and bodily fluids for abnormalties in order to determine the cause of death.
Forensic Antropologists : Examine and collect bones to determine how a person died.
Forensic Etymologists : Deal with how insects in an environment can affect the decomposing process and how long a person's been dead based on the insects in/on/around the body. They usually take samples of insects from around the area, on the person, etc and examine them for their age and development.
Forensic Taphonomists : Deal with the fate of human remains, and are usually able to tell how long a person's been dead by the decompsing state of their body. Also examines how the conditions of an environment may affect the decomposing process such as weather, temperature, scavenging animals, etc. Usually involved with collecting data such as taking temperatures of the body and the area surrounding it over a period of time, recording climates, examining the area for animal markings, etc.
Forensic Toxicologists: Analyze the chemicals in the body for abnormalties in order to determine if drugs, pills, poison, etc were a leading cause in death. Usually work in a clinical setting.
Forensic Photographers : Are on the scene taking pictures from a variety of angles of the area of death.
Forensic Psychologists : Examine the motives behind the crime, and are involved with interviewing criminals.
Forensic Nursing: Deals with more of the legal aspects of forensic science by asissting in criminal prosecution cases, providing care to sexual assault victims, performing consultations with victims, victim's families, or families of the criminals, etc.
How much does a forensic nurse investigator get paid a year?
As of 2023, a forensic nurse investigator typically earns between $60,000 and $100,000 annually, depending on factors such as experience, location, and the specific employer. Those with advanced certifications or in specialized roles may earn higher salaries. Additionally, benefits and overtime pay can also impact overall compensation.
In which year and country was the first case of a conviction based on fingerprint evidence?
Fingerprints were first used as evidence in a criminal investigation in 1892 in Necochea, Argentina. During the investigation of the double murder of the two sons of a woman, Francisca Rojas, police interrogated their prime suspect, Rojas' neighbor, but could not extract a confession from him. In the ensuing investigation, the police presented fingerprint evidence to the mother herself, proving her own fingerprints were imprinted in blood at the crime scene, whereupon Rojas confessed to murdering her own two children.
.
Fingerprints were first used as evidence in a court trial in 1902 in Paris, France, in which Henri-Leon Scheffer was convicted of the murder of Joseph Reibel based, in part, upon evidence of fingerprints left behind on a broken glass case. Scheiffer's fingerprints were deposited upon the glass in such a way, the prosecution successfully argued, that could only be done after the glass was broken, proving Scheffer left behind his fingerprints after the case was broken, and therefore at the scene and time of the murder.

Where can you find forensics crime jobs?
Many colleges in the USA offer courses in forensic science. Amongst the best are Syracuse University in New York, University of California - Davis and Boston University.
How long does it take for a body to decompose after death if it has not been embalmed?
The process of decomposition is the same for everyone, but how much time it would take varies if the body is in a casket buried in the ground. Some may decompose within a few months, and some may take many years. There's no cut-and-dry answer.
What does the 264 and 81 represent in the Originating Address TP-OA 264-81-3358948?
264 is the country code for Nimbia
81 =?
How can class evidence be used to narrow a field of suspects?
Class evidence is material used in a criminal investigation to narrow down a list of suspects. This evidence can help investigators pinpoint a type of product involved in a crime. This can be used to learn more about who would be the most likely suspect.
What grades do you need to be a forensic scientist?
To be accepted onto the course you need at 5 GCSE's, which are grades A* to C.
You need science double award, but it's preferred that you have triple award.
You get accepted with a grade C or above. But bare in mind, the science is really full on and can get quite hard. So it's advised you get a grade B or higher, in Sciences.
You also need grade C or above in Maths, as there is a lot of mathematical equations involved in the assignments.
Science, Eng and Maths, are a must have for this topic.
How do you know if a shooter is left or right handed?
because thats how they could do it either with left or right handed
The word Tracert (or Traceroute) refers to tracing the route that packet information is transferred from point to point. In very simplified terms, every Internet User is assigned an IP address. The IP of a computer allows it to communicate with other computers, using what is called "hops". A hop is a routing destination-middleman that "hands off" the data to the next hop and so on until it reaches its final destination. These "hops" create a trail of data about the user of that one specific computer that is sending and receiving data.

What are the chemicals used in forensic studies?
There are different chemical which are used in forensic studies. The common ones include chloroform, methanol, helium and so many others.
How much does a DNA test for criminal matters cost?
DNA testing for criminal evidence can vary greatly depending on what is being tested - how much is being tested - the type of case - the number of locations where it was collected from - and a whole host of extenuating factors. There is no way to give a standardized response to the question.
If you want to be a CSI - like on the TV show - you need a bachelors degree in a lab science, such as biology, chemistry, forensic science or similar. You usually also need a masters degree in a lab science.
Most people going into the field get their bachelors in biology or chem, and then get their masters in forensic science.
Try to do an internship in forensic science while you study, to make it more likely you'll get a job in the field when you graduate.
Criminal justice degrees are more for if you actually want to be a police officer, a corrections officer, or a security officer. To be a CSI, you need to be a scientist.
What are the advantages of fingerprint evidence?
It is strong physical evidence. It places the person at the crime scene. The person may have been identified through fingerprint evidence and that may be the only way to link the person to the crime scene. Through fingerprints you are able to determine a person's identity. Eye-witnesses can be wrong, fingerprints don't lie.
What is a forensic anthropologist?
Forensic anthropology is the application of the science of physical anthropology and human osteology (the study of the human skeleton) in a legal setting, most often in criminal cases where the victim's remains are more or less skeletonized. A forensic anthropologist can also assist in the identification of deceased individuals whose remains are decomposed, burned, mutilated or otherwise unrecognizable. The adjective "forensic" refers to the application of this sub field of science to a court of law. Answer: Forensic anthropology is the examination of skeletal remains. A forensic anthropologist can first determine if the remains are in fact human. Then he can determine the gender, approximate age, physical stature, their occupation, and likely racial affiliation of the person in life. He can also estimate approximate time since death, likely cause of death and any identifying illnesses or wounds suffered in life that could leave traces in the bone structure.
Generally speaking forensic anthropology is the examination of human skeletal remains for law enforcement agencies to determine the identity of unidentified bones. Further definition of the term is necessary to understand the scope and basis of forensic anthropology. Anthropology alone is the study of man. Anthropologists are interested in culture (cultural anthropologists), language (linguistic anthropologists), the physical remains or artifacts left behind by human occupation (archaeologists), and human remains or bones and teeth (physical anthropologists).
The NRMP match statistics for 2012 and 2011 ranked it in the "low competitiveness" category. In 2012, about half of path positions were actually filled by IMG's. But from 2008-2010 it was ranked in the "intermediate competitiveness" category. Even so, a DO degree shouldnt hinder you from obtaining path so long as you have decent or better board scores. Also, as will any specialties, you can always place somewhere. Comptitiveness varies among programs too. Do relatively well on your board exams and apply broadly, you'll land a path residency.
The "rough" notes and the crime report need only contain enough information to establish that an act occurred which was an offense that broke the law. PC only needs to be shown in order to effect an arrest, therefore, it is necessary only in the arrest report. The forensic report doesn't need to contain anything more than the bare facts of the item(s) under analysis.

Why would someone want a csi job?
there are many reasons why. I myself want to be one, or a forensic scientist, and I want to be one because i want to help people. I don't believe in sending someone into prison unless there's penty of evidence. I also enjoy science, and am good at spotting detail. Many people choose csi as they think it looks fun, but csi can be different from the tv.
Are there any drawback to using PERT?
The PERT approach, even used as originally intended, has been shown to produce inaccurate and biased numbers. We have known of this problem since the early-1960s (MacCrimmon and Ryavek 1962; Archibald and Villoria 1967; Hulett 2007) though some people apparently did not get the memo. The weakness of the PERT process is that it recognizes only the PERT critical path and does not recognize that parallel slack paths can contribute to risk at the merge points. PERT ignores the contribution of those slack paths and hence underestimates schedule risk at the merge points, the well-known merge bias. However we do not know the extent of this bias without doing a Monte Carlo simulation, so we cannot say that the bias is small or minimal. PERT underestimates the risk for all schedules where there are parallel paths, and this means it underestimates risk for all real schedules. This underestimation occurs at each merge point within the schedule structure. Also See: http://blogs.ittoolbox.com/eai/implementation/archives/pros-cons-of-the-pertcpm-method-22221
