Research Basics: Lesson 1 ENGLISH 1021-41 ESSAY FUNDAMENTAL

INSTRUCTIONS:

• Read and watch each web page/video/resource.
• Type a summary of the top takeaways/things you learned from each section/link whether they have a video or not. Each paragraph should have complete sentences and there needs to be at least 4 sentences. Think of it as at least one sentence about each of the four top things you learned from each resource you review.
• So, again, you will type up paragraph for each section/link. Label your paragraphs by each section you are writing about. So, give a heading or label that says: What is Research? Information Cycle, and Planning: Keywords and Search Strings, then add you paragraphs about what you learned in each area. Put these paragraphs all together in ONE WORD DOCUMENT.
• Label it Research Basics: Lesson 1 and submit it all together to the Research Basics: Lesson 1 assignment folder by April 20 at 11:59 pm.

This week you will be looking at these sections/links:

Background: The GC owners have questions and need clarification about several contract concepts and issues related to their new business. Specifically, they have questions about:

• the Statute of Frauds “writing requirement” and
• electronic contracts

Generally, contracts for the sale of goods must be in writing, and the writing must be signed by the parties to the agreement, and the parties must be sufficiently identified. GC will be selling goods via the internet, and the owners are wondering whether these electronic contracts are valid and enforceable.

Background Facts You Need To Know:  Company X, a company in Illinois, contracted via the internet with Windows Bright, a small window washing business in Missouri to purchase four cases of Shiny Lite window cleaning solution at $200 per case. Company X paid via the internet with a company credit card. The contract stated that the four cases of Shiny Lite would be shipped to Company X’s place of business in Illinois via UPS. Once UPS delivered the Shiny Lite, the contract required Windows Bright to clean Company X's windows.

Winne and Ralph have asked you to prepare examples and explanations of the statute of frauds and electronic contracts.

To respond to the GC's questions and concerns, you must prepare a fact scenario and be prepared to discuss the scenarios in a meeting with TLG and the GC owners.

A. Discuss whether the contract between X and Windows Bright is subject to the Uniform Commercial Code Statute of Frauds.

B. Analyze and explain whether the internet electronic contract between X and Windows Bright satisfies the “writing” requirements for the Statute of Frauds? If so, how and why?

Pre-Assignment

hom

Before you start, create a new Eclipse project and create one package in that project. The package should be called “HW3”

Problem 1

Create a class called “Person”. This class should have, at minimum, the following members and methods. I advise you to add others as you see fit.

// Members

firstName (string)

lastName (string)

age (int)

pAddress (Address)  // This is composition! I suggest using the Address class we defined earlier!

pDOB (Date)  // This is composition!  I suggest using the Date class we defined earlier!

// Constructors

Person()  // Default with age = 0, names null, and DOB and Address default for those classes

Person(firstName, lastName, age)  // Address and DOB will be default for those classes

Person( Person x)  // Copy constructor that does a DEEP COPY of the person object.

// Setters

setFirstName(String firstName)

setLastName(String lastName)

SetName(String firstName, String lastName)

setAge(int newAge)

setAddress(String houseNum, String street, String city, String state, String zip)

setDOB (int day, int month, in year)

// Getters

toString()   // Print out the name, age, dob, and address (use toString from DOB and Address)

getAge()  // return the age

getFirstName()   // return the first name

getLastName()  // return the last name

getDOB()   // Return a COPY OF the date object HINT: Use the date copy constructor!

getAddress() // Return a COPY OF the address object HINT: Use the Address copy constructor!

Problem 2

Test your Person class by creating a new class (in the same “HW3” package and then use the methods to make sure they work properly. I provide no guidance on this since all you need to do is test the methods to make sure they work. Call each and make sure they don’t report errors or fail to execute correctly. Fix any bugs you find. Ask for help if you need it!!!

Problem 3

Create a new class file and call it “Student”. This class will EXTEND on the Person class by adding new data members and methods. Note that students are, in fact, people. This extension makes sense!

// Data members

stuID (String)

major (string)  

level (int)    // 0 = first-year,  1 = sophomore,  2 = junior,   3 = senior,  4 = post-grad

// Constructors

Student(String id, String lastName, String firstName, String major, int level)

Student( Student x)  // Copy constructor that makes a DEEP COPY of Student x object

// Setters

Provide one setter for major, one setter for stuID, and one setter for level. Note that the “level” method should check the input to make sure it makes sense. If something besides a 0, 1, 2, 3, or 4 is provided, the setter should write a warning to screen and refuse to make the change.

// Getters

Provide one getter for major, one getter for stuID, and one getter for level.

// Provide an overrided toString method and use super to also use the inherited toString

toString (String)

// This method should write to screen something like this:

// “Jones, Mary, 21, 544 S Winston St., Kemble, KY 00000, Computer Science, 3”

// Note that you want to use the inherited toString() method here by saying super.toString()

// somewhere in your returned expression.

Problem 4

Create a new class in “HW3” package and call it “testStudent”. Use this class to create multiple student objects and person objects. Test all the methods for accuracy. Make sure you have correct behavior for all of your methods/constructors. Watch out for the copy constructors!!!!

6. A 200-kg roller coaster reaches the top of the steepest hill with a speed of 5.80 km/h. It then descends the hill, which is at an angle of 35° and is 41.0 m long. What will its kinetic energy be when it reaches the bottom? Assume µk = 0.18.

1. In the United States, the degree of labor market protection has decreased significantly since 1970’s. Explain the effects of this trend on economic growth in the medium-run and long-run perspective. What are the implications for income inequality in the United States?

The MarsX Space Vehicles Company has been very successful. Due to an increase in demand for its STS’s, the company had to hire thousands of scientists, engineers and staff from all over the world. As we all know, not all countries use the same system of measurements. The U.S., Liberia and Burma use the English system; while the rest of the world uses the metric system. In addition scientists use specific scales for some of their applications. To avoid confusion among team members from different countries, the company has commissioned the development and deployment of conversion applications. Your job is to write a program that interchangeably converts between different temperature scales (Celsius, Fahrenheit and Kelvin).

Your job depends on the success of this application. Therefore, make sure you write clean code and test it thoroughly.

Your program must do the following:

1. Display the menu below and get user input. Re-display the menu until the user enters 4.

1. Convert from Celsius
2. Convert from Fahrenheit
3. Convert from Kelvin
4. Quit Program

2. If the user enters 1, prompt the user to enter 3 numbers that represent temperatures expressed in degree Celsius. The program must then convert the temperatures to degree Fahrenheit and Kelvin and output them in a table as follows:

3. If the user enters 2, prompt the user to enter 3 numbers that represent temperatures expressed in degree Fahrenheit. The program should then convert the temperatures to degree Celsius and Kelvin and output them in a table as follows:

4. If the user enters 3, prompt the user to enter 3 numbers that represent temperatures expressed in degree Kelvin (no negative numbers allowed, validate). The program should then convert the temperatures to degree Fahrenheit and Celsius and output them in a table as follows:

5. If the user enters 4, quit the program.

Needed conversion formulas:

Your program must comply with the following constraints:

1. Must declare at least the following 4 function prototypes:

int getMenuSelection();                  /*Displays menu and gets user selection*/

void convertFromCelsius();             /*From Celsius to the other scales*/

void convertFromFahrenheit();        /*From Fahrenheit to the other scales*/

void convertFromKelvin();              /*From Kelvin to the other scales*/

2. The main function must look exactly as shown below:

int main()

{

int menuSelection = 0;

do

       {

system(“cls”);

menuSelection = getMenuSelection();

             switch (menuSelection)

{

       case 1: convertFromCelsius();

             break;

       case 2: convertFromFahrenheit();

             break;

       case 3: convertFromKelvin ();

             break;

       case 4: break; /*Do nothing. Exit Condition*/

       default: printf(“Please enter a number between 1 and 4 \n”);

system(“pause”);

}

       } while (menuSelection != 4);

system(“pause”);

return 0;

}
