Fatima is 86 years old female admitted to emergency room complains of skin tear of her right leg. She states she fell down and cut her leg. You use a septic technique to clean the skin tear and remove the clotted blood. You positioned the skin flap to approximate the edges of the wound. And then you covered the entire wound bed with a sterile non-stick dressing and bandage. You asked Fatima to come back in one week for reassessment of the wound. You instruct her on how to protect the area, the importance of keeping it clean and dry and signs of infection she needs to be aware of. She demonstrates a reasonable understanding of your instructions. Four days after Fatia has attended the hospital, she re admitted to ER complaining of throbbing pain in her leg at the location of skin tear but radiating up and down whole leg. She rates her pain as 8 out of 10. When you examine leg wound you found it is inflamed in the surrounding tissue and moderate amount of thick yellow exudate being discharged from the wound. Fatima vital signs taken were

BP – 189/92 mmHg

HR – 92 beats/minute

RR – 24 breaths/minute

T – 39.2°C

SpO2 – 95% on room air

She was admitted to the hospital for more active treatment of the wound, including antibiotics.

Joe's Drones is attempting to minimize total inventory cost and maximize profits this year. Each drone costs Joe $100 to buy and he sells them for $150 each. Joe’s mom helps with the purchasing and ordering and he pays her $100 for every order she places. Joe leases warehouse space from a friend where he can store his inventory and he pays $2.50 per month for each board that he has to store to use this space.

Drones are a hot item and Joe expects to sell 2,500 of them this year. He is currently ordering once a month, but he thinks that he can save money if he optimizes his order quantity.

a) If Joe continues to order once a month this year, what will his Total Annual Cost of Inventory be?

b) Assuming Joe sells everything that he orders, what will his annual profit be if he continues to order once a month

c) What quantity should Joe to order that would minimize Total Cost of Inventory (not Total Cost - the is Inventory only)?

d) How much will Joe’s annual profit change if he orders based on the EOQ rather than ordering once a month?

Case study

Susan Chumley has worked at Suspenders Ltd for six months and has been appointed a team leader. In the time she has been there, out of the eight members of her team who were there when she joined three have left and one is on long-term sick after having a breakdown. She has to attend meetings of other team leaders and supervisors. At one of the meetings she was told that certain suppliers were to be given ‘special payments’ providing certain delivery and quality targets were met. These were to be paid directly to named individuals and arrangements would be made to pay them in cash. In the records these were to be described as ‘advisory fees’. Susan and her colleagues were told only to deal with these named individuals and no one else.

After work her friend Maureen asked Susan if she would like some electrical goods that had been ‘damaged’ in the stores. Maureen revealed that stores staff regularly siphoned off consumer electrical goods and sold them cheaply to staff – suppliers simply replaced any damaged goods and didn’t ask for them to be returned so this practice was simple and effective. Maureen had bought a 42-inch plasma television for £100 from one of the stores staff. Susan declined.

At home Susan’s daughter asked her if she could have some paper and pens for school. Susan said she would bring home a packet of paper and a box of pens the next day from the stationery store. Next day Susan finished her work, messaged a friend in Cyprus on Facebook and bought some new outfits for work from some online shopping websites. She then went home, remembering to take with her the pens and paper her daughter wanted.

Discussion Questions

Marks

  1. How has the behavior of the staff been influenced by the ethical behavior of the company?
  2. What are the ethical issues in Susan’s behavior? Is her behavior acceptable or excusable in any way?
  3. How should management deal with incidences of such behavior by staff?
  4. What processes and procedures could be put in place to reduce incidences of this type of behavior by staff and what should management do to make them effective

A system contains a 0.1 molar solution of NaCl and a 0.01 M solution of NaCl separated by an oherise impermeable membrane hat contains a special sodium-conducting pore called an ionophore. The 0.1M solution is inside the membane and the 0.01 Molar solution is outsie the membrane. This ionophore allows free diffusion of the Na+ ions, but not Cl- ions.

Let’s assume the minimum return every year across all the funds is M. This means sum of money invested in stock, bonds, aggressive growth, aggressive value, moderate growth and moderate value in any year will return at least M%.

Keep in mind that the total percentage of money allocated across all the funds in any year will be 100%. This means stocks + bonds + …… moderate value = 100% or 1

The objective here is to maximize return in any year. E.g. in year 1 to maximize return, one can invest all the money in moderate growth, but this will not work because in year 2, moderate value returns higher. Therefore, the objective is to come up with an allocation across all the funds such that the return is maximum in the 5 year period.
