Crime Scene Investigators vs Forensic Scientists - Free Essay Example

I have always had a major interest in crime scene investigations and forensic science, but I did not realize, until these past few years, that they are separate careers almost entirely. However, they do have some similarities in the occupations and the people they work with. On crime shows, such as CSI, the entire crime scene investigation team is made to look like they do the work of the forensic experts as well. Although, in real investigations the crime scene investigators work in the field by collecting evidence and trying to solve the overall case. The forensic scientists then analyze the separate pieces of data in a lab and report back to the investigators. While crime scene investigators and forensic scientists both gather and analyze data from the aftermath of the crime, the two careers differ in many ways. A forensic scientist is a lab technician that processes and analyzes evidence to help law enforcement solve crimes. Forensic scientists tend to do most of their work in laboratories, as their main task is evaluating physical and trace evidence. Their education involves mostly science courses, such as biology and chemistry. They testify in court on behalf of the investigators and medical experts about the analysis of the evidence. Forensic scientists tend to work in a safe environment, as they rarely leave their isolated, controlled lab (CrimeSceneInvestigatorEDU, 2018). A crime scene investigator is often a member of law enforcement that collects and handles physical and trace evidence at a crime scene. Crime scene investigators do their work in the field, finding and preserving the evidence that they find. Their education involves mostly courses on law and criminal justice. They talk with the family and friends of victims to help provide closure and answers. Crime scene investigators work at random job sites every day that could be unsafe or unsanitary (CrimeSceneInvestigatorEDU, 2018). Both occupations are criminal justice based as they deal with the collection and analysis of evidence in order to help the law enforcement solve a crime. Forensic scientists and crime scene investigators earn around the same average annual pay, even though their job descriptions vary greatly. They both require a minimum of a bachelors degree to begin work in their specific job field. Their skills are both equally complementary to the head detectives working to solve the crimes. Forensic scientists and crime scene investigators work together to ensure that the evidence stays untampered and protected throughout the entirety of the case (Ventures, 2016). Crime scene investigators and forensic scientists must testify in court on behalf of the evidence and evaluations they find throughout the course of the case. This requires both occupations to complete detailed forms and reports on their findings as well. Crime scene investigators earn an average of $81,500 a year (CriminalJusticeDegreeSchools, 2018), while forensic scientists earn about $69,000 (Indeed, 2018). They both work about 40 hours a week plus whatever extra work is asked of them daily (CriminalJusticeDegreeSchools, 2018). While both occupations play a pivotal role in interpreting and solving crimes together, they are also completely separate in their fields of work. Crime scene investigators find the evidence in the field, while the forensic scientists analyze it in the lab. Forensic scientists require a more sophisticated level of education, as they have to analyze the evidence using medical and scientific knowledge that they have obtained (Study.com, 2018). Crime Scene Investigators job environments can change on a daily basis, while Forensic Scientists stay in the same comfortable lab daily. Crime Scene Investigators can face harsh and extreme conditions, such as rain and snow, while Forensic Scientists stay indoors in a controllable environment (Williams, 2016). People can apply to be a crime scene investigator with just a specialized degree or experience in a forensic field. This then leads to them getting a background check and on-the-job training. Crime scene investigators must be in good shape and health, as well as, mentally strong, as they will have to deal with mortifying crimes (CriminalJusticeDegreeSchools, 2018). On the other hand, forensic scientists must complete a pre-med minor after, or while, obtaining a bachelors degree in a science-based field. Forensic scientists do not have to be physically fit, however, they must be mentally strong to analyze and evaluate all the evidence that goes through them on a day to day basis. While crime scene investigators and forensic scientists both gather and analyze data from the aftermath of the crime, the two careers differ greatly in every way they are broken down. Forensic scientists process and analyze evidence to help the law enforcement solve crimes. Crime scene investigators collect and handle physical and trace evidence at a crime scene. Forensic scientists and crime scene investigators work together to guarantee that the evidence stays intact and safe during the entirety of the case. The crime scene investigators work in the field by collecting evidence, then the forensic scientists analyze the separate pieces of data in a lab and report back to the investigators.

Job Satisfaction Literature Essay Sample

Some people would say that at 50 it is too late to make any plans for the future or change anything in your life. If you’ve stayed in your job until this age there is no other choice but to select stability and spend the years until retirement in the same position. After all, it is what all people do. Unless you are a late bloomer, of course. This term defines people who have radically changed their life at an age when life is often considered to be coming to an end: at 40, 50, 60, in some rare cases even 70 or 80. The fact of their existence proves that it is never too late to do something with your life, especially if you are not satisfied with how it has been going so far. And if you want to get acquainted with individual examples, read the book â€Å"Late Bloomers† by Brendan Gill. Written almost two decades ago, it is still one of the best works you may find on this subject – Brendan Gill collected the stories of 75 individuals who found their purpose in life well after they should have resigned to their fates and accepted slow decline. Instead of that they made the second half of their lives fulfilling, interesting and fascinating. According to the stories of these people, gradual movement in a chosen direction is far from being necessary to achieve success at any stage of your life. For example, Harland Sanders, also known as Colonel Sanders, in the course of his long life has tried himself at being a fireman, a lawyer, an insurance salesman, a secretary in a ferry company, a filling station manager and a dozen other professions. However, he wasn’t really interested in any of these ventures, nor did he succeed much in them. This all changed after he started his Kentucky Fried Chicken franchise at the age of 65, which in the course of time turned out into an enormous international enterprise. Similar to his is the story of Raymond Kroc, who has been a middling milkshake machine salesman until the age of 52, when he got tired of his job, left it and joined McDonald’s to turn it into the most successful fast-food chain in the world. These are just two examples from 75, and these 75 are just a small fraction of people who refused to accept what their life was giving them and made something else entirely of it. The majority of these people didn’t have any specific background, education or enormous fortune which would allow them to easily change their direction in life and their lifestyle in general – they were ordinary people, just like you and me. The only thing that made them different from the majority is the fact that they weren’t afraid of trying something new, of leaving the stable situation they found themselves in and starting out anew – even though those around them certainly found their efforts to be amusing that late in life. They did nothing that cannot be repeated by anybody else – assuming this anybody has real will to do so. â€Å"Late Bloomers† teaches us that if you are not satisfied with your job, that if you are being kept in your profession by nothing but your own inertia, apathy and fear of change that is inherent to all human beings, the difference between change and status quo is your will to do what you want. If a person really wants to find fulfillment and satisfaction in life, there is nothing to stop him or her, and it doesn’t matter how old he or she is.

Cognitive Science The Scientific Study Of The Mind

Midterm Exam Question 1-Cognitive Science is defined as the scientific study of the mind. Cognitive Science uses the scientific method as it primary methodology. One of the main features of cognitive science is the multifaceted method, and it uses linguistics, robotics, neuroscience, cognitive, the evolutionary approach, psychology, the emotion approach, the social approach, philosophy, and artificial intelligence (Friedenberg and Silverman, 2012). Cognitive Science uses all these different methods mentioned above, and this is why cognitive science is different. It takes form linguistic, philosophy, and neuroscience, etc. As a result, the traditional cognitive psychological view does not utilize all these fields and areas of study, and this is why cognitive science applies to almost everything we breath, feel, and touch; therefore, cognitive science applies and intertwines all these different fields of study (Friedenberg and Silverman, 2012). Cognitive Science refers not so much to the sum of all disciplines but to their connection or diverging work on specific problems. Cognitive Science is a combined effort among researchers working in numerous fields (Friedenberg and Silverman, 2012). The cement that holds Cognitive Science together is the topic of the mind, and the use of scientific methods.
