Assignment:

Most critical analysis papers begin with a short summary of the work and then dive into the argument. Since most of these paper assignments are short, it is important to be concise in all parts of your analysis. Please respond to the questions below with at least one paragraph for each question. Please use your own words. 

1. What is the overall aim of the research being presented?
2. Are the aims of the research and the results of the data clearly and concisely stated in the abstract? Provide a summary of the abstract.
3. Does the introduction provide sufficient background information to enable readers to better understand the problem being identified by the Authors? Provide one example.
4. Have the Authors provided sufficient evidence for the claims they are making? Provide some examples.
5. Provide at least 3 examples from the literature review section.
6. What was the methodology used in this journal? Be specific.
7. The conclusions should match the data being presented. Provide some examples presented in the paper that support the conclusion.
8. Discuss the implications of this research.
9. What was the main contribution of this research to the body of knowledge?
10. What additions or research questions would you add to this journal?

Write three pages document. No need APA format and citations

Calculations are there

Please a topic from the below list and create a one-page essay answering the question noted below.    

• Define the IT organizational structure and how the IT organizational structure impacts culture and change management practices.  Additionally, how does the organizational structure impact competitive advantage?
• How do you define operational excellence?  What factors are involved in achieving operational excellence?  Who (within an organization) is responsible for operational excellence and why is this important?

** Please note you have minimal space and time to complete the assignment, do NOT write an introduction, rather just answer the selected question noted above. This is a test of both knowledge and your ability to be succinct in messaging**

Please review table 1.2 in the text and review the distinction between leadership and management.  Then think about this in regard to how senior leaders versus senior managers lead change in an organization (especially when it comes to technical change in an organization).

Answer the following questions:

When implementing change in an organization, there are always culture issues that are faced, such as not accepting change, determine how differently this would be handled thinking about the management versus leadership constructs?

When dealing with performing work, how is this implemented differently within the management versus leadership constructs?

1. Discuss the pros and cons of the memory management schemes presented in this chapter. If given an option, which scheme would you implement and why?
2. Discuss the difference between associative memory and cache memory and the steps involved in using these types of memory.

Need As Soon As possible.

 Write in essay format not in outline, bulleted, numbered or other list format.  

Use the five paragraph format. Each paragraph must have at least five sentences. Include 3 quotes with quotation marks and cited in-line and in a list of references. Include an interesting meaningful title.  

 Place the words you copied (do not alter or paraphrase the words) in quotation marks and cite in-line (as all work copied from another should be handled). The quotes should be full sentences (no more, less) and should be incorporated in your discussion (they do not replace your discussion) to illustrate or emphasize your ideas.

Cite your sources in a clickable reference list at the end. Do not copy without providing proper attribution (quotation marks and in-line citations).

You will need to download the R studio, tidyverse, and associated packages if you don’t already have them.

Q3. 

In this exercise you’ll use R package tidyverse (see chapter 4 of Introduction to Data Science Data Analysis and Prediction Algorithms with R by Rafael A. Irizarry. You need to go through chapter 4 before attempting the following questions. Using dplyr functions (i.e., filter, mutate ,select, summarise, group_by etc. ) and “murder” dataset (available in dslab R package) and write appropriate R syntax to answer the followings: 

a. Calculate regional total murder excluding OH, AL, and AZ (Hint: filter(! abb %in% x) # here x is the exclusion vector) 

b. Display the regional population and regional murder numbers. 

c. How many states are there in each region? (Hint: n ()) 

d. What is Ohio’s murder rank in the Northern Central Region (Hint: use rank(), row_number()) 

e. How many states have murder number greater than its regional average (Hint: nrow() ) 

f. Display 2 least populated states in each region (Hint: slice_min() ) 

Use pipe %>% operator for all the queries. Show all the output results  

For this week’s research paper, you need to search the Internet and explain the following:

1. Why are some businesses are accepting and other businesses are rejecting the use of Bitcoins as a standard form of currency? Compare and contrast this with other cryptocurrencies. Your paper needs to identify two major companies that have adopted Bitcoin technology.

2. Take a position, either 1) cryptocurrency is a fad that will fade, or 2) cryptocurrency is a legitimate representation of wealth that will persist and grow. There are rigorous resources available on either side of the argument to lend credibility to your case. Regardless of your choice, clearly state 2-3 factors succinctly.

Paper should meet the following requirements:

• Be approximately 4- 5 pages in length, not including the required cover page and reference page.

• Follow APA guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.

• Support your response with the readings from the course and at least five peer-reviewed articles or scholarly journals to support your positions, claims, and observations.

• Be clear with well-written, concise, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

• Using search engines and find two different recent articles involving data mining. Describe the role of “data mining” in the story using your own words.
