CSI Analysis Draft

Although this is only a draft, you should try and get as close to this decription as possible.  Have a paper that is mainly done will allow you to receive the maximum amount of feedback from your Peer Reviews.

Project Description:

Watch an episode of CSI (any of the versions) on network TV or by using an Internet service such as Hulu.com. Take notes about actions taken by the scientists. Then, write an analysis of the episode, detailing which actions taken are realistic and which ones are not. For two actions that are not realistic, discuss what the scientists would have done if the scenes were always realistic.

You need to use outside sources when writing this paper. The sources you use for this assignment should include at least two outside sources or articles. One of your outside sources can be any of the provided classroom readings. Significant amounts of information from these outside sources should be incorporated into your paper. Wikipedia is NOT an appropriate outside source for any college level paper and should not be used as an outside source in this paper. Also, your CSI episode should be referenced but does not count as one of your two other outside sources.

In addition to presenting information from your sources, do some significant critical thinking in applying the course material and material from the outside sources to the CSI episode and your analysis of this episode. To show your critical thinking and that you incorporated your outside references into your paper, no more than 10% of your paper may be quotations.  The majority of your paper must be written in your own words.

Make sure that you provide citations throughout your paper.  Remember that for any information you receive from outside sources, whether you quote it, paraphrase it or summarize it, you must provide citations telling the reader where that outside information came from. Make sure that you provide citations for the episode as well as your outside sources. 

Your paper should contain the following items:

Cover/Title Page

  • Body of Paper
    • 900-1,500 words long
    • Introduction
    • Short episode synopsis
    • Episode Analysis, including the following items:
    • Realistic and non-realistic actions taken by the actors
    • 2 non-realistic actions further discussed
    • 2 non-realistic actions analyzed for how those actions would have been performed in the “real world”
    • Analysis must incorporate information received from 2 outside sources
    • Conclusion
  • References Page

Format of Paper

  • Times New Roman font ONLY
  • 12 point font
  • 1 inch margins (you will have to change your margins if using Word 2003 or earlier)
  • Double Spaced

The paper does not need an abstract. It should be in APA format, including the citations and the References.

“Tchaikovsky and Women in Art” Please respond to one (1) of the following, using sources under the Explore heading as the basis of your response:

  • Select one (1) composition by Tchaikovsky that you enjoy. Describe the music and subject matter of that work, and explain why you enjoy it. Explain the key reasons why you believe that compositions by Tchaikovsky continue to be popular with contemporary orchestras and audiences. Passionate nationalism, like Tchaikovsky’s for Russia, could be a feature of Romantic art and music and in the arts of the late 1800s. Give primary examples of music today (besides national anthems) that is characterized by nationalism.
  • Select two (2) paintings depicting females by both a male artist and female artist named within the Explore section. Compare and contrast these two (2) depictions of women, and comment on any general tendencies that you detect among artists of that era in this respect. Compare this situation in the late 1800s to the way females are depicted in our own modern times, using at least one (1) specific modern example.

Fossil Fuels versus Renewable Energy

/in /by

 

In physics, energy is defined as the ability to do work. When most people think of energy, they think of electricity. The energy that is used to produce electricity is derived from a number of resources. Much of the energy used today is obtained from fossil fuels. However, these resources are limited. As a result, alternative and renewable resources are being explored for production of electricity.

Using the readings for this module, the Argosy University online library resources, and the Internet, respond to the following:

  • Discuss the scientific and technical concepts related to the uses of fossil fuels and renewable energy resources.
    • Consider how fossil fuels such as coal, oil, and natural gas are utilized for production of electricity.
    • Consider how alternative and renewable resources such as wind turbines, hydroelectric power, wave power, and geothermal energy are utilized to either produce electrical energy or provide an alternative to electricity consumption.
  • Explain the advantages and disadvantages related to both fossil fuels and renewable energy resources such as wind power, hydroelectricity, geothermal energy, and biomass.
    • Consider issues such as availability of the resource, sustainability of the technology, and environmental impact.
  • Provide 2–3 examples of the uses of both types of energy resources that are utilized in your community.

Support your statements with examples. Provide a minimum of three scholarly references.

Write your initial response in 2–3 paragraphs. Apply APA standards to citation of sources.

Review and comment on at least two peers’ responses.

Part 1: This is a chance for you to make the connection between your behavior and actual neuron growth in your brain. The idea is that the activities you choose to be involved with today, create the person you will be in the future.  And so for this topic, describe the person you want to become in five years time. What new things will you learn that will stimulate an advanced and diverse neural network in yourself? Be sure to discuss the challenges you might encounter along the way and what you will need to do to overcome them. Here are some examples of what to write about:
a. Your career choice, and what skills and education it requires.
b. How you will be a member of your community, as an active participant or leader.
c. What choice of home culture you will pick for your own family.
d. Which healthful living activities such as diet, exercise, or meditation will you choose?
e, What new hobby would you pursue? Is it individual or team-related?
f. Or any other example of how you will have developed over those the next five years.

Part 2: This topic involves a kind of fast-forwarding in the development of the mind. There is research going on today that aims to create computer chips for placement in the human mind to help with various functions. The chips are intended to inform us or help us make decisions. For example, a chip could be implanted to identify diseases in the body, calculate our blood pressure, tell us when our diet isn’t providing sufficient vitamins, or even tell us when we need sleep. Other possibilities are numerous. The questions for this Discussion topic are, which of these functions, if any, would you like a brain-chip for:  larger memory storage while you are in school…  a chip that helps you with creativity…  a chip that helps you control your emotions… a chip to help you understand what is best for you, and how to choose that path.  Then discuss why you are willing to give up part of your human nature in favor of a new, possibly improved digital nature.  Can you co-exist with a mini-computer in your brain?
