Assignment 2: Media and Crime Log—Entry II

In this module, you will have an opportunity to add to your media and crime log by applying theories presented in this course to media portrayals of crime. The American public is fascinated with crime and therefore, there is no shortage of media depictions of crimes and criminals. In this assignment, you will use the scholarly knowledge you have gained in the course to analyze how the media portrays crime.

You are now familiar with biological, psychological, and sociological theories of crime. In M2: Assignment 2, you wrote a log entry applying psychological theories of criminal behavior to analyze articles or news stories. In this assignment, you will write your second log entry.

Research newspaper or magazine articles related to crime using the print or online news media.

Select two articles or news stories and apply at least two theories from the biological, psychological, and/or sociological perspectives to each article or news story.

Write an analysis of each article or news story addressing the following:

• What is the purpose of the story as you perceive it?
• How is crime or criminal justice portrayed?
• What feelings or reactions are evoked in you by the article?
• How would you explain the reported criminal behavior using the two theories you selected? Explain your choice of theory.

Give complete citation for the selected article and include a digital copy if possible.

Write a 2–3-page log entry in Word format. Apply APA standards to citation of sources. Use the following file naming convention: LastnameFirstInitial_M4_A2.doc.

Assignment 8.1

Do NOT submit .java files.  Please submit a zip file of your source code.
Implement a modified version of the card game WAR.  In this game there will be two players, and each player will be dealt 26 cards.  The players do not get to choose which card they will play.  Instead, the top card from each of the Hands is played, so a total of two cards are played.  The card with the higher value wins, giving the player who played it a point.  After 26 rounds the game is over and a winner should be declared based on points.
In the event of a tie between cards.  For example 5 of clubs vs. 5 of hearts, the tie will be broken as follows:
diamonds (lowest value), followed by clubs, hearts, and spades (highest value)
So in this case, the 5 of hearts beats the 5 of clubs.

STEP 1: Understand the UML Diagram
Analyze and understand the object UML diagram, which models the structure of the program.
⦁ The Employee class has been specifed as abstract, which is denoted by the name of the class being italized Employee
⦁ The Employee class as a new method CalculateNetPay which is an abstract method, denoted by the italized name of the method. Since this method is an abstract method the CalculateNetPay method WILL NOT have an implementation in the Employee class.
⦁ The Salaried and Hourly classes both have a new method CalculateNetPay that is inherited from the abstract Employee class and the Salaried and Hourly class both MUST implement the CalculateNetPay method.
STEP 2: Create the Project
You will want to use the Week 5 project as the starting point for the lab. Use the directions from the previous weeks labs to create the project and the folders.
⦁ Create a new project named “CIS247_WK4_Lab_LASTNAME”. An empty project will then be created.
⦁ Delete the default Program.cs file that is created.
⦁ Add the Logic Tier, Presentation Tier, and Utilities folders to your proejct
⦁ Add the Week 5 project files to the appropraties folders.
⦁ Update the program information in the ApplicationUtilities.DisplayApplicationInformation method to reflect your name, current lab, and program description.
Note: as an alternative you can open up the Week 5 project and make modifications to the existing project. Remember, there is a copy of your project in the zip file you submitted for grading. Before attempting this week’s steps ensure that the Week 5 project is error free.
STEP 3: Modify the Employee Class
⦁ Modify the class declaration of the Employee class to specify that the Employee class is an abstract class
⦁ Declare an abstract method called CalculateNetPay that returns a double value.
⦁ Modify the ToString Method to include the weekly net pay in currency format.
STEP 4: Modify the Salaried Class
⦁ Add a double constant called TAX_RATE and set the value to .73
⦁ Implement the CalculateNetPay method by multiplying the weekly pay by the tax rate.
STEP 5: Modify the Hourly Class
⦁ Add a double constant called TAX_RATE and set the value to .82
⦁ Implement the CalculateNetPay method by multiplying the weekly pay by the tax rate.
STEP 6: Create the Main Program
⦁ Change the employeeList array to only hold two objects
⦁ Create one Hourly employee object and store it in the array.
⦁ Create one Salaried employee object and store it in the array.
⦁ As you did in the Week 5 lab, prompt for and collect the information for each of the objects.
Note: iterating through the array should not require any changes from the previous iteration of the project–but make sure that the loop stays within the bounds of the array.
STEP 7: Compile and Test
When done, compile and run your program. Then debug any errors until your code is error-free.
Check your output to ensure that you have the desired output and modify your code as necessary and rebuild. The output of your program should resemble the following:

STEP 8: Submit Deliverables
⦁ Capture the console output window and paste into a Word document.
⦁ Put the zip file and screen shots (Word document)

1- In your opinion, what is the importance of portfolio revision and the role of common types of formula plans in timing purchase and sale decisions. What is your take on progression of the Markowitz portfolio model into the capital market theory? Are you applying it in your own portfolio project? .                                       

2.What are the techniques used to measure the amount invested, current income, capital gains, and total portfolio return relative to the amount of money actually invested in the portfolio? Do you think that Statistical measures and uses like Sharpe’s, Treynor’s, and Jensen’s Information ratio measures are effective to measure portfolio return?

3.Discuss the investment process and the general steps relating to it. Briefly discuss the three phases in the investor life cycle. Explain the dilemma posed when attempting to measure the risk tolerance or preferences of a client, especially as it relates to (a) indifference or utility curves and, (b) Prospect Theory What is the importance of every financial advisor creating an investment policy statement for each client

4.What is the duration of a bond? How was duration considered in the selection of bonds in your portfolio management project? Contrast the differences between option writing and option buying? How would you have considered the selection if NOT used in your portfolio?

5.Briefly explain why having similarly correlated assets in a portfolio may actually be more risky than having assets with a low degree of correlation. Describe how historical and expected relationships between assets aid in the generation of an “efficient frontier” of potential portfolios for consideration.                                                                       

Distinguish between strategic asset allocation and tactical asset allocation. Briefly explain how the “January effect” anomaly contradicts the efficient market hypothesis or theory. Give examples to substantiate your answer.

6.How is the current Investment News of Ali Baba and Yahoo’s collaboration as well as the Initial Public Offering of the Company in US Markets? How it may affect the Investment possibilities of many investors in USA? How would you evaluate the effect of latest Ecoli scare at some Chipotle’s restaurants on their stock prices?

 

Assignment 1. Linear Programming Case Study

 

 

 

Your instructor will assign a linear programming project for this assignment according to the following specifications.

 

 

 

It will be a problem with at least three (3) constraints and at least two (2) decision variables. The problem will be bounded and feasible. It will also have a single optimum solution (in other words, it won’t have alternate optimal solutions). The problem will also include a component that involves sensitivity analysis and the use of the shadow price.

 

 

 

You will be turning in two (2) deliverables, a short writeup of the project and the spreadsheet showing your work.

 

 

 

Writeup.

 

 

 

Your writeup should introduce your solution to the project by describing the problem. Correctly identify what type of problem this is. For example, you should note if the problem is a maximization or minimization problem, as well as identify the resources that constrain the solution. Identify each variable and explain the criteria involved in setting up the model. This should be encapsulated in one (1) or two (2) succinct paragraphs.

 

 

 

After the introductory paragraph, write out the L.P. model for the problem. Include the objective function and all constraints, including any non-negativity constraints. Then, you should present the optimal solution, based on your work in Excel. Explain what the results mean.

 

 

 

Finally, write a paragraph addressing the part of the problem pertaining to sensitivity analysis and shadow price.

 

 

 

Excel.

 

 

 

As previously noted, please set up your problem in Excel and find the solution using Solver. Clearly label the cells in your spreadsheet. You will turn in the entire spreadsheet, showing the setup of the model, and the results.

Case Problem Mossaic Tiles, Ltd.  Taken from page 108 in the textbook

 

 

 

Gilbert Moss and Angela Pasaic spent several summers during their college years working at archaeological sites in the Southwest. While at those digs, they learned how to make ceramic tiles from local artisans. After college they made use of their college experiences to start a tile manufacturing firm called Mossaic Tiles, Ltd. They opened their plant in New Mexico, where they would have convenient access to special clay they intend to use to make a clay derivative for their tiles. Their manufacturing operation consists of a few relatively simple but precarious steps, including molding the tiles, baking, and glazing. Gilbert and Angela plan to produce two basic types of tile for use in home bathrooms, kitchens, sunrooms, and laundry rooms. The two types of tile are a larger, single-colored tile and a smaller, patterned tile. In the manufacturing process, the color or pattern is added before a tile is glazed. Either a single color is sprayed over the top of a baked set of tiles or a stenciled pattern is sprayed on the top of a baked set of tiles. The tiles are produced in batches of 100. The first step is to pour the clay derivative into specially constructed molds. It takes 18 minutes to mold a batch of 100 larger tiles and 15 minutes to prepare a mold for a batch of 100 smaller tiles. The company has 60 hours available each week for molding. After the tiles are molded, they are baked in a kiln: 0.27 hour for a batch of 100 larger tiles and 0.58 hour for a batch of 100 smaller tiles. The company has 105 hours available each week for baking. After baking, the tiles are either colored or patterned and glazed. This process takes 0.16 hour for a batch of 100 larger tiles and 0.20 hour for a batch of 100 smaller tiles. Forty hours are available each week for the glazing process. Each batch of 100 large tiles requires 32.8 pounds of the clay derivative to produce, whereas each batch of smaller tiles requires 20 pounds. The company has 6,000 pounds of the clay derivative available each week. Mossaic Tiles earns a profit of $190 for each batch of 100 of the larger tiles and $240 for each batch of 100 smaller patterned tiles. Angela and Gilbert want to know how many batches of each type of tile to produce each week to maximize profit. In addition, they have some questions about resource usage they would like answered.

 

 

 

A. Formulate a linear programming model for Mossaic Tiles, Ltd

 

 

 

B. Solve the linear programming model by using the computer and determine the sensitivity ranges

 

 

 

C. Mossaic believes it may be able to reduce the time required for molding to 16 minutes for a batch of larger tiles and 12 minutes for a batch of smaller tiles. How will this affect the solution?

 

 

 

D. The company that provides Mossaic with clay has indicated that it can deliver an additional 100 pounds each week. Should Mossaic agree to this offer?
