Discuss Howell and Mendez’s three perspectives on followership. Note how these behaviors influence work productivity.

 

Week 15 Discussion

After completing the reading this week, we reflect on a few key concepts this week:

Discuss Howell and Mendez’s three perspectives on follower-ship. Note how these behaviors influence work productivity.

What is the big five personality model?

What is the Myers-Briggs test? How is it similar to the Big five model? How is it different than the Big five model?

Please be sure to answer all the questions above in the initial post.

Please ensure the initial post and two response posts are substantive. Substantive posts will do at least TWO of the following:

Ask an interesting, thoughtful question pertaining to the topic

Expand on the topic, by adding additional thoughtful information

Answer a question posted by another student in detail

Share an applicable personal experience

Provide an outside source

Make an argument

At least one scholarly (peer-reviewed) resource should be used in the initial discussion thread. Please ensure to use information from your readings and other sources from the UC Library. Use APA references and in-text citations.

Countermeasures used in a Crisis Response

The media loves to tell the horror stories of disasters after security breaches. I.S. professionals must pro-actively plan countermeasures and continually study and learn from past events. Select a past news story of a failure caused by one of these events to provide an analysis of the failed system using some of the countermeasures you have learned in this unit. Recommend strategies to minimize the loss of I.S. services/data in those events as if you had been on the IT team during this event. Keep in mind that the focus of this assignment is the response to a crisis – after the event (not preventing the event).

Countermeasures to consider for your responses:

  • Fix known exploitable software flaws
  • Develop and enforce operational procedures and access controls (data and system)
  • Provide encryption capability
  • Improve physical security
  • Disconnect unreliable networks

Please submit a three to four-page report with APA cited references to support your work.

Reflective Paper (Cloud Computing)

 

Provide a reflection of at least 500 words (2 pages double spaced excluding Title and Reference pages) that summarizes what you feel are the most important or interesting concepts you have learned so far in this Cloud Computing course.  Would be good to include an insight as to whether the learning was new to you or reinforced knowledge that you already had.

Requirements:  Provide a 500-word (2 or more pages double spaced not counting the title and reference pages) paper.  The paper should include a title page, body pages, and reference page.  An abstract and introduction is not required for this assignment.  Correct use of APA guidelines for sources and citations is required. If supporting evidence from outside resources is used those must be properly cited.

Business Intellegence

Discussion: 

Research Apple Home Pod. How does it interact with smart home devices?  Alexa is now connected to smart home devices such as thermostats and microwaves. Find examples of other appliances that are connected to Alexa and write a report. 

Discussion Questions: 

1.Compare the IoT with regular Internet. 

2. Discuss the potential impact of autonomous vehicles on our lives. 

3. Why must a truly smart home have a bot? 

4. Why is the IoT considered a disruptive technology? 

Exercises: 

1. AT&T is active in smart city projects. Investigate their activities (solutions). Write a summary. 

2. It is said that the IoT will enable new customer service and B2B interactions. Explain how. 

3.Find information about Sophia, a robot from Hanson Robotics. Summarize her capabilities. 

Database (2) database design

1-Write the relational algebra expressions for the following (using Ç):
branch (branch_name, branch city, assets)
customer (customer_name, customer street, customer city)
loan (loan number, branch_name, amount)
borrower (customer name, loan number)
account (account_number, branch name, balance)
depositor (customer_name, account number)
a) Find the names of all customers who have a loan and an account at bank. 
b) Find all customers who have an account from at least the “Downtown” and the “Uptown” branches. 
2- University schema
Classroom (building, room number, capacity)
Department (dept name, building, budget)
Course (course id, title, dept_name, credits)
Instructor (ID, name, dept_name, salary)
Section (course id, sec id, semester, year, building, room number, time slot id)
Teaches (ID, course id, sec id, semester, year)
Student (ID, name, dept_name, tot cred)
Takes (ID, course id, sec id, semester, year, grade)
Advisor (student ID, instructor ID)
Time slot (time slot id, day, start time, end time)
Prereq (course id, prereq id)
Write the following queries in SQL, using the university schema
a) Find the names of all students who have taken at least one Comp. Sci. course; make sure there are no duplicate names in the result
b) Increase the salary of each instructor in the IT department by 15%. 
c) Insert every student whose tot cred attribute is greater than 75 as an instructor in the same department, with a salary of $15,000. 
3- Refer to the university schema used in Q.2 and write the following queries using Nested subqueries.
a) Find the average instructors’ salaries of those departments where the average salary is greater than $50,000. (Hint: use subqueries in the From Clause)
b) Delete all courses that have never been offered (that is, do not occur) in the section relation. 
4- Deleting a record can be costly to an organization if not done in the right way. Let us assume you are working as a DBA (database administrator) and you used the delete command without specifying a condition in the where clause. What do you think will happen to the record in the database? And in case a record was deleted, is there a way to recover the lost data? Answer should be in your own words.
