Crime scene management and investigation refers to the activity that goes on at an actual crime scene rather than in a forensics laboratory. However, the physical and trace evidence gathered in the field at a crime scene will eventually be analyzed in a forensics laboratory and the analyses conducted govern the types of evidence collected at a scene. Many individuals tend to accept as absolute truth that forensic laboratory testing and results are scientific in nature. However, much criticism has been leveled in recent years that many of the techniques used have never been validated and no known error rates have been established. Without this information, we cannot be sure how often forensic examiners make errors in judgment or to what extent these errors are influenced by what the examiner already knows about the case. This has broad implications in criminal investigation.

For this week’s assignment, you will step out of the crime scene and into the forensics laboratory for a look at some known issues and criticisms in forensic laboratory testing as well as in credentialing someone to be classified as an “expert” forensic examiner. It is beneficial to understand what happens with the evidence collected at the crime scene once it goes to the laboratory. Your research for this paper may cause you to question the reliability and validity of commonly relied upon forensic evidence in criminal trials. However, your job as a scholar (and criminal investigator) is to evaluate objectively what you are learning and arrive at a conclusion that is based on information from credible sources.

First, watch the Frontline documentary The Real CSIand then discuss the following in your paper using the National Academy of Sciences 2009 report (Chapters 2, 4, and 5) as a credible resource to support your assertions:

• Summarize the Brandon Mayfield case, focusing on the idea that no two fingerprints are alike despite the fact that this has never been tested. Identify what type of testing would need to be done to ensure that the assertion that “no two fingerprints are alike” is true? Examine whether or not this type of testing is feasible and why or why not.
• Analyze what role cognitive bias might play in influencing the forensic lab results of tests in areas such as fingerprint identification, firearms identification, bite mark identification, or the “smell of death” technique described in the Frontline film.
• There is much criticism that techniques used in fingerprint identification and other types of forensic identification described in the NAS report (Chapter 5) are inherently unscientific because there have been no validation studies. Without validation studies that establish known error rates, these methods cannot be said to be scientifically sound. Recommend whether or not to use commonly accepted scientific techniques that have not been scientifically validated and supports these recommendations with research materials.
• Suggest at least one intervention to overcome the effects of cognitive bias that may influence a forensic examiner’s identification decision.
• Analyze the type of training and credentials forensic examiners should have in order to work in a forensics lab. Provide recommendations for training and credentialing forensic examiners to ensure that they are adequately trained.

The Forensic Identification: Science or Pseudoscience? Paper:

The environmental controversy for this week revolves around the use of paper or plastic bags, and whether the consumer should have to pay for them.

Plastic bags are thought to harm the environment, and thus raise several different issues. Along with this issue comes the “precautionary principle.” This principle states that all new chemicals and technologies should be assumed to be harmful until proven otherwise and that all commercial products that are suspected of being harmful must be removed from the market until studies can demonstrate that they are safe. 

dvocates of the principle argue that when dealing with chemicals and technologies, it is better to be safe than sorry. Critics reply that nothing is absolutely safe and that the precautionary principle is unrealistic and would seriously hinder the development of needed drugs, pesticides and other products. Furthermore, the costs of thoroughly testing all controversial chemicals and technologies to prove their “safety” would be prohibitive. 

What do you think of these statements?  With whom do you agree or disagree and why?

Resources: PowerPoint Guidelines from Library and Chapter 16 in your textbook.  You have been instructed by your Chief of Police to prepare a presentation for in-service training regarding types of computer crimes. These can be computer, computer-related, or technology crimes.  Create a 5-8 slide PowerPoint Presentation incorporating speaker notes identifying at least four crimes that can involve computers.  Include the following in your presentation. •Identify four or more computer related crimes. •Describe each of the four crimes with a complete description of how each crime could be committed supported with resources.  Format your presentation consistent with the following guidelines:  Use at least two additional sources outside of your course textbook.  Cite all sources using APA format and ensure your references are in your speakers notes or you will be cited with plagarism.  Include a title slide and reference slide in addition to the length requirements.  Use one basic slide layout for the design.  Use speaker notes to fully explain what is being discussed in the bullet points as though you are presenting to an audience.

Listen to the teaching video on “Exploring the APA Clinical Practice for Treatment of Depression” (found in Module 1) . 

Discuss three (3) key issues from the video that you needed to hear, and explain to us why that information was important to you.

Discuss how your dominant personality traits may help patients suffering from depression recover from the disorder more effectively.  Explain why.

Identify any of your attitudes toward the disorder that may hinder a person with depression from being able to work effectively with you.  How can you improve your perspective on the disorder?

Task Aim :

The aim of this assignment is to demonstrate your knowledge and understanding of community health nursing concepts and principles, specifically community profile and needs assessment, as well as community engagement. You will also demonstrate your ability to collect and analyse community-level data and plan a community needs assessment. 

This written assignment will address learning outcomes 1, 2 and 3. 

TASK DESCRIPTION: 

There are two parts to this task. 

For Part A you are to create and populate a table with ABS census data and present data for your community, Queensland and Australia using 2016 census data from the Australian Bureau of Statistics (ABS). 

For Part B you are to write a 1500 word essay in which you will describe the process of community assessment and explain your assessment of the community of choice.
