retainAll

Write a method called retainAll that takes two sets of integers as parameters and that removes any values in the first set that are not found in the second set. 

For example, given sets: 

s1: [0, 19, 8, 9, 12, 13, 14, 15]  

s2: [0, 19, 2, 4, 5, 9, 10, 11]  

If the following call is made: 

retainAll(s1, s2);  

after the call, the sets would store the following values: 

s1: [0, 19, 9]  

s2: [0, 19, 2, 4, 5, 9, 10, 11]  

You are implementing a two-argument alternative to the standard Set method called retainAll, so you are not allowed to call that method to solve this problem. 

You are also not allowed to construct any structured objects to solve the problem (no set, list, stack, queue, string, etc) although you can construct iterators. 

Your method should not change the second set passed as a parameter.

Find a peer-reviewed scholarly journal article discussing electronic innovation and the government. Complete a review of the article by writing a 2-3 page overview of the article. This will be a detailed summary of the journal article, including concepts discussed and findings. Additionally, find one other source (it does not have to be a peer-reviewed journal article) that substantiates the findings in the article you are reviewing. 

You should use the Google Scholar to find these types of articles (https://scholar.google.com/ )

Once you find the article, you will read it and write a review of it.  This is considered a research article review.

Your paper should meet these requirements: 

• Be approximately three to four pages in length, not including the required cover page and reference page.
• Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. 
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

Data Quality and Security

The reading in the text provides two key reasons for poor data quality, “the rush to install new systems and the failure to take an integrated view of the organization’s data” (p. 109). Data security breaches seem to occur every other day, and as discussed in the Week Three lecture, there are serious implications for organizations that do not take the necessary measures to ensure data security. Include the following elements in your paper supporting your statements using the required sources for this assignment.

Analyze the role of data in information systems for business and describe the risks that can arise from poor data quality.

Explain the challenges that can result from poor data quality. Provide an example of the results of poor data quality from your own personal or professional experience.

Explain at least two methods of how organizations can ensure good data including the structure and applications necessary.

Analyze the risks of poor data security.

Research an article in the popular media that covers a recent data breach. Explain the impact of the data security breach on the organization and its leaders using evidence from your article.

Explain the role of data governance in keeping data secure.

Week 10 – Discussion

Many people believe that the use of biometrics is an invasion of privacy. For example, an eye scanning device records the inner structure of a person’s eye and stores that image in a database. Critics worry that databases of human traits used to maintain corporate security may actually pose a privacy threat to individuals, if such data were used in other ways. In your view, are such concerns justified? Why or why not?

Writing Assignment – Wk 10

Some common biometric techniques include:
