Annotated Bibilography

 

Please find 5 research articles related to the topics discussed in Chapter 5. 

Topics could include:

  1. System dynamics
  2. Multi-actor systems modeling
  3. Complex adaptive systems modeling

or any other topic contained in the chapter.

After reading and finding the 5 research articles, create an annotated bibliography. The deliverable will be one MS Word file that you will submit here. Please make sure that there are at least 150 words per article, this does not include references or copies of the abstract or introduction, this must be what you come up with. 

Analyzing & Visualizing Data

  

Background: Quantitative data can be measured and documented with numbers. Additionally, quantitative data can be represented as quantities. On the other hand, qualitative data is not measured with numbers, but it is represented by qualities. For example, I use quantitative methods to conduct my PhD research because I like working with counts and measures.

Assignment: Write a research paper the contains the following:

  • Discuss Quantitative Methodology
  • Discuss Qualitative Methodology
  • Compare and contrast qualitative data vs quantitative data

Your research paper should be at least 3 pages (800 words), double-spaced, have at least 4 APA references, and typed in an easy-to-read font in MS Word (other word processors are fine to use but save it in MS Word format). Your cover page should contain the following: Title, Students name, Universitys name, Course name, Course number, Professors name, and Date.

Unit 5 Discussion

Instructions

For the discussion this week, conduct research on the topic you have been working with since Unit 2. Then, in a well-developed  initial post, include the following:

  • A description of your research process
  • Three APA reference entries, each for a credible source related to your topic
  • Beneath each reference entry, include an annotation of the source

Finally, select one of the sources and provide a full evaluation of it in terms of the CRAAP criteria. That is, explain its currency, its relevance, its authority, its accuracy, and its purpose.

The three sources you select may be used, if you wish, in your final annotated bibliography that is due at the end of the unit.

Please be sure to validate your opinions and ideas with citations and references in APA format.

Annotated Bibliography – Depth

 

paper will be an annotated bibliography, specifically focusing on the “Depth” topic (i.e. Defense in Depth) in the context of protecting National Infrastructure.

You paper must be in correct APA format, use correct grammar, and will need to include at least seven (7) resources, ALL of which must:

1) Be current. Published within the last few years.

2) Be peer-reviewed.

3) Relate directly to Defense in depth in the context of protecting National Infrastructure.

Analysis of Requirements

Please the following to paragraphs and answer replies. They should be thoughtful and supportive with references.

1.Prototyping is in itself a self-sufficient mechanism to collect system requirements and can take two forms, evolutionary and throwaway. The main benefit of prototyping is the development of an information system that more closely fits the needs of the organization (Huston, T.H. & D’Ouville, E. L., 1988). A prototype is a basic working model, mock-up or a simple simulation of the product which leads us to create a minimal viable product to final product and variations (Entrepreneur, 2018).

While, evolutionary prototypes are generally turned into a full working production system at some point in time, the throwaway prototypes, as the name suggests, are discarded once they meet the initial purpose they were created for. Agreed that there may be some cases where throwaway prototypes dont even serve the purpose for which they were created. However, after having spent so much resources and effort on these prototypes, which met initial purpose, is it justifiable to discard them? If so, under what conditions it makes business sense to discard these prototypes?

2. My post this week will not be too verbose as I have had a perplexing question (that I have some opinions on, but I’d like the thoughts of the class) that has been a theme for these discussion posts throughout this course.  After reading both chapters this week I appreciate the needs for systems requirements and data flow diagrams.  I understand the benefits of both; The outcome of a detailed requirements analysis is that the organization reaps the benefits of selecting best-fit software (Doig, 2015).  However, the thought that has captured my curiosity is what are the costs to an organization for poor systems requirements, and/or data flow diagrams?  For example; An unclear product spec can add millions of dollars in manufacturing costs (Redman, 2013).  Aside from monetary impacts, what other types of impacts does shoddy work do to an organization?

Data Analysis

 

Background: This course is all about data visualization. However, we must first have some understanding about the dataset that we are using to create the visualizations.

Assignment:

  • Use RStudio to generate a word document with basic data analysis of the following dataset (also included in separate section) :    

Questions/Requests:

  • Create a summary of stats for the dataset. (provide a screen shot)
  • Create a correlation of stats for the dataset. (provide a screen shot) (Hint: Transform may be needed)
  • What is the Min, Max, Median, and Mean of the Price? (provide a screen shot)
  • What is the correlation values between Price, Ram, and Ads? (provide a screen shot)
  • Create a subset of the dataset with only Price, CD, and Premium. (provide a screen shot)
  • Create a subset of the dataset with only Price, HD, and Ram where Price is greater than or equal to $1750. (provide a screen shot)
  • What percentage of Premium computers were sold? (provide a screen shot)(Hint: Categorical analysis)
  • How many Premium computers with CDs were sold? (provide a screen shot)(Hint: Contingency table analysis)
  • How many Premium computers with CDs priced over $2000 were sold? (provide a screen shot)(Hint: Conditional table analysis)

Cryptography

  You want  to build a hardware device to do block encryption in the cipher block  chaining (CBC) mode using an algorithm stronger than DES. 3DES is a good  candidate. shows two possibilities, both of which follow from the definition of CBC. Which of the two would you choose and why: 

 

  1. For security?
  2. For performance?
