4. Environment Recycling, Inc. must clean up a large automobile tire dump under a state environmental cleanup contract. Some of the activities can be crashed. The tasks, durations (in days), costs, predecessor relationships, the crash times, and costs associated with performing the activities at their original (normal) times and for the crash times are shown as follows:

a. Find the total project completion time. (Show all work including finding the critical path).

b. Find the lowest cost solution if the state wants to complete the project two days early. State which activities need to be crashed and calculate the crashing cost for the total project.

Write the functions needed by the main function that is given.

multiply2nums should accept 2 values and return the product (answer you get when you multiply).

greeting should accept one value and print an appropriate greeting using that value. For example, if you sent "Steven" to the greeting function, it should print "Hello, Steven"

DO NOT CHANGE ANYTHING IN main()

def main():
user = input("Please enter your name ")
greeting(user)
try:
num1 = int(input("Please enter an integer "))
num2 = int(input("please enter another integer "))
result = multiply2nums(num1,num2)
print("The product of your two numbers is ",result)

What happened at Revlon?

As F. Nicholas Jacobs toured the Windber Medical Center facility, he was dismayed by the industrial pink-painted walls, the circa 1970 furniture, and the snow leaking through the windows of the conference room. Employees earned 30 percent less than their counterparts in the area, and turnover was steep. As Windber's newest president, Jacobs knew he was the facility's last hope, if he couldn't successfully turn around the aging facility, it would mean closing the doors forever.

Coming to Windber Medical Center in 1997, Jacobs was keenly aware that the hospital could be the next in a series of small hospitals that had fallen victim to a struggling economy. Determined to see that not happen, he began by making connections with the employees of the hospital and the community at large. Jacobs's first step was to interview the employees to find out firsthand what they wanted for the Windber community and the medical center. He also looked to members of local community groups like the local library, the Agency on Aging, and local politicians and asked these groups what they wanted from their local medical facility. When Jacobs realized that people of over 80 years of age made up a larger percentage of the population in Windber, Pennsylvania, than in all of Dade County, Florida, he made it a priority to provide more options to seniors for improving their health and quality of life. He set forth a vision of a medical center that was more of a community center, a center that would allow members of the community to exercise in a state-of-the-art facility while having access to professionals to answer health related questions. Jacobs realized that keeping people in the community both physically and mentally healthy also meant keeping the hospital financially healthy. He made the center's new preventive care philosophy clear to the public: "Work out at our hospital so you can stay out of our hospital."

Jacobs's efforts have paid off in an era when small hospitals are closing left and right, Windber Medical Center is thriving. Under Jacobs's leadership, Windber has established an affiliation with the Planetree treatment system, which integrates meditation, massage, music, and other holistic methods into traditional healthcare. Windber's wellness center, which offers fitness training, yoga, and acupuncture, among other treatments, opened in January 2000 and now generates over $500,000 annually. Gone are the pink walls and dated furniture, replaced with fountains, plants, and modern artwork. Jacobs recruited a former hotel manager to oversee food service. And despite the dismissal of about 32 employees (those used to a more traditional hospital setting had a tough time in the new environment), the staff has nearly doubled to 450 employees, and pay has improved. Windber has raised more than $50 million in public and private funding and has forged research partnerships with the Walter Reed Army Health System and the University of Pittsburgh, among others. The Windber Research Institute, Windber's heart disease reversal program, has treated about 250 patients.

Please explain in as much detail as possible each of your answers, explain your reasoning.

QUESTIONS:

Hersey and Blanchard’s Situational Leadership Theory

1. Given the information that you have, what do you think was the level of follower readiness (willingness and ability) overall of the hospital employees? What behaviors should Jacob engage in, given the followers’ readiness?

2. In you assessment did Jacob’s engage in such behaviors? Explain

Fielder’s Contingency Theory

3. Using Fielder’s Contingency Theory, which octant do you think the situation at the hospital falls into at the beginning of Jacob’s tenure? Which would be the most appropriate leadership style for this situation (Task motivated-Low LPC, or Relationship motivated-high LPC)?

4. Jacob’s scored high LPC-Relationship motivated, is this the appropriate style for your assessment of the situation? What situational factors, if any, could be changed to make the situation more favorable to Jacob’s leadership style?

Consider the following un-normalized relational table on an online retail store orders and payments information:

An online retail store would like to create a database to keep track of its sales activities. Information recorded in the database supposed to include customer number that identifies each customer, customer’s first name, last name, unique order number of orders a customer made, the date when an order was made, unique product number of products included in orders, product description, sequence number listing the sequence when a product is included in each order as well as the quantity for each product made in each order. The retail store would also like to store the payment information such as a credit card number of credit card that was being charge to, payment date and the amount paid. The online retail store allows customer to pay using any one of the credit cards the customers own, as long as the credit card is valid.

A database designer created the following relational schema:

CUSTORDER(custNum, custFName, custLName, orderNum, orderDate, prodNum, prodDesc, itemNum, quantity, cCardNum, paymentDate, amountPaid)

Decompose the relational schema into the smallest number of relational schemas each one in forth normal form (4NF) and to explain or justify that each schema is in 4NF. To justify that the relational schemas obtained from the decomposition are in 4NF you must find all functional and multivalued dependencies valid in each relational schema, you must find the minimal keys, and then apply the definitions to support your justification. Note, that a relational schema is in 4NF when it is in BCNF and it does not have any nontrivial multivalued dependencies. It means, that first, you have to prove that a schema is in BCNF and later show that it has no nontrivial multivalued dependencies. Please keep in mind that the smallest number of 4NF relational schemas is expected

Task: The below table shows socio-economic data of two fictitious countries. From the perspective of a business considering the possibility of undertaking business in these countries, consider what the data could mean and present three conclusions. Each conclusion should compare both countries using at least two variables. You can relate each conclusion to any type of international business (eg. you can present a conclusion from the perspective of a business choosing a new export market, a business seeking an import source, a business choosing a location for FDI, etc). Recommended length for each conclusion: approximately 200 words.                                           (4 marks per conclusion)

A Lab question asks whether the relationship between atomic number and electronegativity is direct, log, or inverse. I am inclined to say that it is direct since electronegativity increases with atomic number; though my out of my various graphs, the one graphing atomic number vs. log of electronegativity has the best line of fit (highest R^2) so I want to say it has a log relationship. Is this correct?
