Discussion 7

The article on IRB this week discusses broad consent under the revised Common Rule. When you are doing any sort of research you are going to need to have your research plan approved by the University’s institutional review board or IRB. If you have never heard of this term before, please take a look online and find a brief summary of what it is about, before you read the article.  

Please answer the following questions in your main post:

  • What are the main issues that the article addresses?
  • What is the Common Rule?
  • How is this issue related to information systems and digital privacy?

At least one scholarly source should be used in the initial discussion thread. Be sure to use information from your readings and other sources from the UC Library. Use proper citations and references in your post.

provide a graduate-level response to each of the following questions:

  1. What are the practical implications internally (in terms of team motivation) and externally (for the customer) of making overly optimistic project delivery promises?

2.Consider a project to build a bridge over a river gorge.  What are some of the resource constraints that would make this project challenging?

3.It has been argued that a project schedule that has not been resource-leveled is useless.  Do you agree or disagree with this statement?  Why or why not?

 Activity 6

Case Study 11.1: It’s an Agile World

This case illustrates a common problem in software and IT development, where programmers and IT staff are anxious to lock in specifications as early as possible so they can “get to work” without having to worry about invasive or disruptive input from the end users.  Unfortunately, what typically happens is that the finished product is not what the users needed or thought they needed and a long list of fixes and modifications are needed to make it work correctly.  This case is based on a true story in a hospital IT department that routinely struggled with these sorts of user conflicts until they sifted to an Agile methodology.

Questions

  1. Why does the classic waterfall project planning model fail in this situation?  What is it about the IT department’s processes that leads to their finished systems being rejected constantly?
  2. How would an Agile methodology correct some of these problems?  What new development cycle would you propose?
  3. Why are “user stories” and system “features” critical components of an effective IT software development process?
  4. Using the terms “Scrum,” “Sprint,” and “User stories,” create an alternative development cycle for a hypothetical software development process at Northwest Regional Hospital.

Case Study 12.2: “First Come, First Served”: Resource Challenges for Sunrise Restoration

This case is intended to highlight the challenges in resource assignment, particularly in the common cases where project managers within the same firm are competing with each other for the use of scarce and valuable human resources to accomplish their tasks.  Without clear guidance from top management and a valid priority system, the ability to acquire resources is often the result of chaotic bargaining and negotiation among equals. This case is based on a real situation and the outcomes were very much in line with the way they are described in the case.  The business owner did not want to simply invest in more resources for fear that they would be underutilized.  He much preferred the system of negotiating among his project managers, even if that led to inefficient utilization of the resources that were available.  Students can be asked to take the side of the owner or Tyler to debate the options that Sunrise can use to manage its resources.

Questions

  1. Describe some of the resource constraints that Sunrise and its project managers are facing.
  2. Is Sunrise’s current model of prioritizing resource assignments viable?  Why or why not?
  3. How could technology alleviate some of Sunrise’s resource management issues?
  4. Would Tyler’s suggestion to hire additional technicians and purchase more equipment solve the resource problems at Sunrise?  Why or why not?

R programming

Module Assignment

Module 4

QMB-6304 Analytical Methods for Business

Write a simple R script to execute the following:

Preprocessing

  1. Load into R the data included in “Assignment 4 Data.xlsx”.  This data set shows age (years), weight (pounds), and height (inches) for 251 adults.  This will be your master data set.
  2. Create a new variable in the master data set which will be each individual’s body mass index.  The calculation should be done as:

BMI=(weight* .45)(height* .025)2

  1. Using the method presented in class and applying the numerical portion of your U number as a random number seed, take a random sample of 45 cases from the master data set. This will be your primary data set.

Analysis

  1. Use R to conduct a simple linear regression on the data with weight as the independent variable and bmi as the dependent variable.  As a part of this be sure to:
    1. Report the beta coefficients and associated p values and confidence intervals from your model.
    2. Give a written interpretation of your beta coefficients in terms of the actual case at hand.
    3. Assess your model’s conformance with the LINE assumptions of regression.
    4. Give a prediction using your model for an individual weighing 185 pounds. Include 95% confidence and prediction intervals and written interpretations of both intervals.
  2. A 10-year-old boy has been presented to you who weighs 72 pounds.  Give two reasons for why it would be wrong to use your model to predict the boy’s BMI.

Your deliverable will be a single MS-Word file showing 1) the R script which executes the above instructions and 2) the results of those instructions.  The first line of your script file should be a “#” comment line showing your name as it appears in Canvas.  Results should be presented in the order in which they are listed here.  Deliverable due time will be announced in class and on Canvas.  This is an individual assignment to be completed and submitted by the time stated on Canvas.  No collaboration of any sort is allowed on this assignment.  Please remember the prohibition on using screen shots in your deliverable.

Big Data analytics

 This week’s reading centered around how Big Data analytics can be used with Smart Cities. This is exciting and can provide many benefits to individuals as well as organizations. For this week’s research assignment, you are to search the Internet for other uses of Big Data in RADICAL platforms. Please pick an organization or two and discuss the usage of big data in RADICAL platforms including how big data analytics is used in those situations as well as with Smart Cities. Be sure to use the UC Library for scholarly research. Google Scholar is the 2nd best option to use for research. Your paper should meet these requirements:

  • Be approximately four to six 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. The UC Library is a great place to find resources.
  • 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.
