[1] Make a calibration curve using the absorbances for the samples from 0.5 – 20 ppm. Include the intercept (0,0) as a data point.

[2] Is the calibration linear, i.e., does the analysis follow Beer’s law? To discuss linearity, examine both the trend of the data relative to the least squares line and the correlation coefficient.

[3] Use a 2nd order polynomial (in Excel’s plotting function) to determine if the fit improves and include this curve.

[4] Explain why AAS often has a limited linear dynamic range compared to say, UV/VIS and fluorescence spectrophotometry

Questions

• What company and industry have you selected, and what are some of the risks that the company and industry are facing in the current economic and political environment? You need to research risks from current financial publications (e.g., Bloomberg, The Financial Times, The Economist). Note: For this assignment, a current publication is no older than four years. Quote your source.
• Has the company addressed these risks? If yes, how? If not, what should they have done?
• Is another competitor on the market facing the same risks, and how did they address them? Briefly summarize.

Answers

The company I have decided to focus on is Marriott. Marriott was founded in 1927 in the United States. Marriott has hotels in over 87 countries and has 19 brand names. Recently, there had been a merge between Marriott and another major hotel brand, Starwood Hotels. Starwood was officially taken over by Marriott in 2018, to create the largest hotel company in the world (Whitmore, 2018). Whitmore also mentions the merger will create the largest loyalty program as well.  

            The political risks Marriott faces are international terrorism. With hotels continuously growing and building in other parts of the world, there is always the fear of terrorist attacks happening. Jan Freitag (2017) explains that in an area where a terrorist attack has happened, there is no normal curve of demand since they all behave differently. She says that when hotels rely more on leisure travelers, then the hotel is affected more in the short term. Hotels are continuing to grow and expand into different countries of the world and most of them are thriving. Hotels, including Marriott, need to make sure their staff is trained in what they need to do in order to protect themselves and their guests at all times. Marriott has taken into consideration the risks of international terrorism and has trained their staff on the importance of protecting their guests and the procedures that need to be taken.

            The economic risks Marriott is facing are taxation changes. When a guest books at a hotel, that hotel charges taxes per night you stay there. The taxes differ on each state. The room rate is the price in which is taxed with state and local tax fees. The Department of Taxation and Finance (2012) explains that “Hotel operators must collect sales tax on the room rate or rental charge for hotel occupancy.” Hotels must charge these taxes to their guests for their hotel occupancy. On top of taxes, some “touristy” places may charge an additional fee such as a “resort fee.” Marriott has addressed these risks as they charge their guests the taxes per night as well as a resort fee when staying in a touristy area.

            Any company in the hotel industry has to address these risks. These risks are not just a Marriott companies problem, they are a hospitality industries risk as a whole. The Hilton, Hampton Inn and other hotel brands have these risks and have taken the same measurements the Marriott Corporation has in order to make sure their company succeeds.

For chegg: Please note I have answered the questions above already. What I am asking of you is to provide a analytical feedback. No plagiarism. In your response to the above post, please provide feedback, including different examples related to the risks and their impacts on the specific industry or company.

Famous artists Georgia O'Keefe and Alfred Stieglitz donated 101 artworks to Fisk University in the 1940s. But the gift had two conditions: The pieces could not be sold and they had to be displayed as one collection. Over 50 years later, Fisk could not pay to maintain the collection and decided to sell two of the pieces. Proceeds of the sale would go to restore its endowment and build a new science building. The Georgia O'Keefe Foundation sued to stop the sale, arguing that the artists would have opposed it.

Should the law permit this sale?

Do you agree with Fisk's actions?

Hotel California is a small modern-style hotel located not too far from the Central Bangkok District. Your job is to write a simple piece of software to manage the room occupancy. The hotel has two buildings; each building has four floors; and each floor has a different number of rooms. Building A has five rooms on each floor. Building B has four rooms on each floor. Each room is graded with Standard, Deluxe, and Suite, and the rates per night are $100, $250, and $600 respectively. In both buildings, the rooms on the first and the second floors are Standard; the rooms on the third floor are Deluxe; and the rooms on the fourth floor are Suite.

Write a program that allows the hotel front desk to reserve a room for its customers. When a customer reserves a room, he needs to provide his name (first name and last name), his phone number and the room grade. The system must check for the availability of that room grade. If the preferred room grade is available, the reservation number will be generated and the room number will be assigned to that reservation. If there are no rooms of that grade available, a proper message must be shown.

Note that the hotel policy allows only 1 room with 1-night stay per booking. If the customer wants to book more than one rooms, he needs to make more reservations. The hotel allows the room to be booked only one day in advance. Hence, the system will only have the booking for tomorrow's check-in.

The front desk should also be able to record the payment for a reservation during the customer's check-out process (given a reservation number, the customer's name or the customer's phone number). If the customer has more than one reservations made on that day, the list of reservations must be shown so the front desk can apply the payment to such a reservation. In order to keep track of the hotel's income, the staff should be able to print the sales reports for each building (grouped by the room grades).

Playland at Pacific National Exhibition is an amusement park offering 31 different rides (including 4 rollercoasters and 1 water ride). The guests who are 48” or taller can go on any ride they want and so they get more value from visiting the park; let us say their individual demand is given by P = 5 – 0.25qO, where P is the price per ride ($ per ride) and qO is the number of the rides (per day) (the subscript O stands for “One Day;” that’s how the park calls its passes for the guests who are 48” or taller). The guests who are under 48” are not allowed on certain rides so they get less value from visiting the park; let us say their individual demand is given by P = 4 – 0.25qJ, where P is the price per ride ($ per ride) and qJ is the number of the rides (per day) (the subscript J stands for “Jr. One Day;” that’s how the park calls its passes for the guests under 48”). Assume it costs the park flat ¢25 per guest to operate a single ride, and it costs the park flat ¢75 to issue a single ticket to a ride. Assume there are 500 guests 48” or taller and 500 guests under 48” on an average day. We can consider Playland a monopolist in Vancouver.

If Playland employed a second-degree price discrimination scheme (single ride tickets are issued, each rider receives a book of tickets [qO or qJ]),

10. what would be the size qO of a package for guests 48” or taller (number of rides with a One Day admission)?

11. what would be the price TO of a package for guests 48” or taller ($ for a One Day admission)?

12. what would be the size qJ of a package for guests under 48” (number of rides with a Jr. One Day admission)?

13. what would be the price TJ of a package for guests under 48” ($ for a Jr. One Day admission)? 14. what is Playland’s profit on an average day ($ per day)? Assume zero fixed cost.
