Endangered Species

Imagine a world without rhinoceroses, or cheetahs, or elephants, or humpback whales, or whooping cranes, or passenger pigeons, or Carolina parakeets, or ivory-billed woodpeckers….

Actually, it is easy to imagine world without the last three on that list. They are already extinct. Extirpated. Gone forever.

As we enter the 21^st century, the human population continues to rise. Many of you may recall a time when there were only 4 or 5 billion people on the Earth. Now there are over 7 billion, and by 2020 there will be 8 billion. And we all need natural resources to survive—sources of food and water and raw materials. We all need land. We all need energy.

Because of those needs, we continue to encroach on other living creatures, different species that collectively form the biodiversity of life on Earth—the variety and richness of life.

This week, we are exploring efforts to restore and sustain that biodiversity in one place; Gorongosa National Park, Mozambique, Africa. Most large mammals were killed off across the region during 35 years of civil war. Now they are making a comeback, and scientists are documenting it. In fact, in this week’s Critical Thinking activity, you will be participating in that process, as a citizen scientist.  

For our discussion this week, let us each imagine an African savanna ecosystem without one of the animals currently living there. To do this, go to the Gorongosa National Park Field Guide (Links to an external site.) and select a mammal or bird pictured there. Click on its picture for a brief overview of the animal; you may want to supplement that information with additional online research. When you have completed your research, answer the following questions:

1. What animal did you choose?
2. What is its preferred habitat?
3. What food does it eat?
4. What animals prey on it?
5. What might be different about the savanna if your chosen animal were to go extinct? How might its extinction affect plants and animals of the savanna, and or the savanna landscape?
6. What arguments can you offer as to why this animal ought to be protected?

As you discuss the different animals that you have researched as a class, consider interrelationships between your animal and the animals your peers have chosen, along with the different reasons that students have identified for protecting the biodiversity of Gorongosa. Are some animals more valuable to the savanna than others? Are some reasons for preserving biodiversity more valid than others?

Your post must be formatted according to the CSU-Global Guide to Writing & APA (Links to an external site.).

Your initial posting should be 250-500 words and must be submitted by Thursday, midnight, of this week.

Assignment 1 Part A - Confidence Intervals and Hypothesis Testing
(One Population)
1. The shoulder height for a random sample of six (6) fawns (deer less than 5 months old) in a national park was , ? = 79.25 cm with population standard deviation ?= 5.33 cm. Compute an 80% confidence interval for the mean shoulder height of the population of all fawns (deer less than 5 months old) in this national park. Analyze the result to interpret its meaning. (10 points)

2. A random sample of 732 judges found that 405 were introverts. Construct a 95% confidence interval for the proportion. Interpret the meaning of the confidence interval. Justify your use of a confidence interval based on a normal distribution for data regarding proportions that are normally following a binomial distribution. (10 points)

3. It has been determined that 37 out of 100 adult Americans that did not attend college believe in extra-terrestrials. However, from a random sample of 100 adult Americans that did not attend college 43 claim that they believe in extra-terrestrials. Does this indicate that the proportion of people who did not attend college and who believe in extra-terrestrials has changed? Conduct a hypothesis test with a = 0.01 and interpret the results. (10 points)

Assignment 1 Part B – Inference (Two Populations), Chi-Squared Tests
1. In a study of brain waves during sleep, a sample of 29 college students were randomly separated into two groups. The first group had 15 people and each was given ½ liter of red wine before sleeping. The second group had 14 people and were given no alcohol before sleeping. All participants when to sleep at 11 PM and their brainwave activity was measured from 4-6 AM. The group drinking alcohol had a mean brainwave activity of 19.65 hertz and a standard deviation of 1.86 hertz. The group not drinking alcohol had a mean of 6.59 hertz and standard deviation of 1.91 hertz. Compute a 90% confidence interval for the difference in population means of groups drinking alcohol before sleeping and those not drinking alcohol before sleeping. Explain the meaning of the confidence interval. (10 points)
2. Discuss the following: (10 points)
 What type of data can be examined using the Chi-Squared Test?
 What is the only constraint in using Chi-Squared Tests?
 What problems can be caused by the way the data have been grouped?

Consider the following independent situations, all of which apply to audits of entities for the year ending 31 December 20X7:

(i) Slipway Limited, a listed company, has been experiencing declining sales over the last 2 years. Cost cutting has proved difficult due to the high level of imported machinery used in Slipway’s operations and consequently margins have been falling. While the bankers are presently happy to continue providing Slipway with loan facilities, they do expect to see improved results in the next financial report. Articles about Slipway’s expected financial results appearing in recent press reports all had quite a pessimistic tone.

(ii) Discount Foods Limited is a large supermarket chain with offices in all capital cities around Australia. Until 30 June 20X7 data processing relating to payroll transactions will be carried out in each capital city by an independent computer service bureau. \

(iii) Getaway Pty. Limited is a long established firm which has been operating a boutique hotel in the Blue Mountains for over 20 years. During this time, it has adopted a conservative business strategy that has seen it produce adequate, though slightly unimpressive, results. A new CEO has been appointed to run the firm from 1 September 20X7. He has already released his plans for renovating the hotel, despite not officially serving as CEO yet. You have also heard him discuss the implementation of a new marketing strategy to boost occupancy rates.

(iv) Angora Pty. Limited is a small primary producer specializing in the production of angora wool. Angora’s recent display at a trade show has seen orders flood in from overseas buyers. The accountant, Michael, has done his best to satisfy the orders as quickly as possible while maintaining the appropriate (foreign currency) accounting records. However, from some of the questions he has been asking you, you suspect he is out of his depth.

(v) Kings Pty. Limited has been manufacturing uniforms for the Australian market for the last 40 years. The government’s recent tariff reduction policy has placed Kings in direct competition with cheaper uniforms manufactured overseas. In a bid to retain market share, Kings has been selling part of its school uniform range at less than cost. However, overall profit figures remain buoyant.

Required: For each of the above independent situations describe the overall impact on audit risk and identify the specific component(s) of audit risk affected.

Task: For each of the scenarios below, choose the strategy that you believe should be pursued to achieve the best results, and provide a brief explanation of why you believe this is the best strategy.

Choose from theses 5 Generic Strategies : 1. Low-Cost Provider Strategy 2. Broad Differentiation Strategy 3. Focused Low-Cost Strategy 4. Focused Differentiation Strategy 5. Best-Cost Provider Strategy

Scenarios: 1. A new waterfront development project is beginning in a medium-size city. This project will include moderate to higher-end shopping, restaurants, and hotels. Some of these businesses include: Pottery Barn, Ann Taylor, an Apple Store, Sasha’s Dress Boutique, Apostrophe, Bose, Calvin Klein, Cheesecake Factory, Capital Grille, Maggiano’s, the Marriott, and the Westin. The spaces will include a mixture of national chains, and local businesses. The project and the city have been highlighted in national papers for the expected success of the project and renewed attraction to the city. The Sully Hospitality group is determining if they want to open a boutique hotel in this area. What strategy should Sully adopt to develop the type of boutique hotel would best- fit this project? Provide a brief explanation.

2. A new shopping center is being developed – the main anchors are Wal-Mart and Home Depot. The other parcels will include smaller establishments of fast-food and other convenience category businesses. McDonald’s is interested in this project but has to determine how they would approach this location. The options are: 1. Put a McDonald’s Express inside the Wal-Mart 2. Purchase an out-parcel at the front of the project with high traffic volume and build a traditional McDonald’s 3. Purchase an out-parcel at the front of the project with high traffic volume and build a McCafe Which generic strategy should be McDonald’s use to guide this decision? Based on the generic strategy that you believe is most appropriate for this scenario, which option should McDonald’s choose? Provide a brief explanation.

3. The airline industry has seen various players attempt all of the generic strategies. Given the current state of the airline industry and the main surviving airlines, if a company wanted to get into this industry right now, which strategy would promote the best chances for success? Provide a brief explanation.

4. The top five selling brands of tablets in the world are: 5. Acer, 4. Dell, 3. Sony Vaio, 2. Lenovo, and 1. Apple. A new start-up company wants to break into the tablet market; what generic strategy should they adopt? Provide a brief explanation.

Trivago Ramps Up Finance Team After Material Weakness By Nina Trentmann Feb 8, 2018

Rolf Schroemgens, co-founder and chief executive officer of Trivago, center, cheers with employees during the company's initial public offering (IPO) in New York, U.S., Dec. 16, 2016. PHOTO: BLOOMBERG NEWS Hotel-search company Trivago N.V. has expanded its financial reporting team as it prepares to file its next annual report, said Chief Financial Officer Axel Hefer. The German company, which listed on the Nasdaq in late 2016, disclosed that it found a material weakness in internal controls over financial reporting in the lead up to its initial public offering. At the time, Trivago was heavily reliant on outside consultants and advisors to meet U.S. reporting requirements. “We now have significantly more people that are experts on U.S. Generally Accepted Accounting Principles,” CFO Axel Hefer Wednesday said in an interview with CFO Journal. The expanded staff have helped overhaul Trivago’s reporting process, which is now “completely different,” Mr. Hefer said. The hotel-comparison company is still assessing whether the circumstances that resulted in the material weakness have been mitigated, Mr. Hefer said. Trivago plans on filing its annual report in the next couple of months, he added. The Securities and Exchange Commission requires foreign issuers that have listed equity shares on U.S. exchanges to submit an annual report within six months after the end of the company’s fiscal year. Mr. Hefer did not share how many people have been added to the company’s reporting team or the number of employees in the finance and accounting department. Mr. Hefer last year said the company would phase out reliance on external accounting help. Düsseldorf-based Trivago currently employs over 1,400 people. Trivago Wednesday swung to a wider-than-expected quarterly loss amid reduced spending from advertisers. The company reported a fourth-quarter net loss of €9.6 million ($11.8 million), compared with net income of €0.1 million for the same period last year.

For today's lab we will be using the Car Object Class which we built in Lab 1. I have attached my solution if you would prefer to use my solution instead of your own solution.

We will working on remembering how to build sub-classes and user interfaces. So we will be creating new Java files for:

• An Interface called GreenHouseGasser
  • Requires a method called CO2() which returns how much carbon dioxide the Object produces.
  • Make sure to update Car so that Car implements GreenHouseGasser. Cars should produce 1.5 units of CO2 for every mph the car is traveling.
• A Car sub-class called SportsCar:
  • Overrides the accelerate() method. SportsCars accelerate twice as fast as regular Cars
  • Overrides the CO2() method. SportsCars should be using a factor of 3.25 units of CO2 for every mph
• A Car sub-class called EcoCar
  • Overrides the accelerate() method. EcoCars accelerate 25% as fast as regular Cars
  • Overrides the CO2() method. EcoCars should be using a factor of .33 units of CO2 for every mph

As your are building/updating your objects, remember to test. You'll need update the Driver to test your new methods and Objects!

Submit all of your .java files in one jar or zip file.

Grading Breakdown:

• Driver tests all new methods and objects -- 25%
• Interface created correctly and Car updated to implement the Interface -- 25%
• SportsCar correctly created -- 20%
• EcoCar correctly created -- 20%
• JavaDoc comments! -- 10%

Here is the Car Object pre-made:

public class Car
{
private String name;
private int currentSpeed;
  
public Car(String inName)
{
name = inName;
}
  
public void accelerate()
{
currentSpeed += 10;
}
  
public void park()
{
currentSpeed = 0;
}
  
public void printCurrentSpeed()
{
System.out.println("Current Speed is: " + currentSpeed);
}
}

Here is the driver that is supposed to be used:

public class Driver {
  
   public static void main(String[] args) {
       // create new Audi car
       Car audi = new Car("Audi");
       // create new Nissan car
       Car nissan = new Car("Nissan");
      
       // print current speed of Audi - it is 0
       audi.printCurrentSpeed();
      
       // call the accelerate method twice on Audi
       audi.accelerate();
       audi.accelerate();
      
       // call the accelerate method once on Nissan
       nissan.accelerate();
      
       // print current speed of Audi - it is now 20 mpH
       audi.printCurrentSpeed();
       // print current speed of Nissan - it is 10 mpH
       nissan.printCurrentSpeed();
      
       // now park the Audi car
       audi.park();
      
       // print current speed of Audi - it is now 0, because the car is parked
       audi.printCurrentSpeed();
   }
}

Discussed persuasive messages and how they are meant to convince an audience to act or change beliefs.The following letter was written from a program chair to a well-known, and very hard to get, gourmet chef in Beverly Hills. The letter is meant to request for the chef to present to a local restaurant association but it is not very persuasive or professional.

Analyze the letter to determine how it could be more persuasive and professional. Consider all the components of effective persuasion discussed in the lesson. Answer the following questions.

What is your initial response to the the way the chair wrote the letter to the chef?

What are at least five weaknesses you identify in the letter, based on concepts learned in the lesson?

In what way could each of the components of AIDA (attention, interest, desire, action) be more effectively implemented in the letter? How would you specifically improve the letter using each component?

--------------------------------------

Dear Ms. Mazzetti:

We know you are a very busy hospitality professional as chef at the Beverly Hills Hotel, but we would like you to make a presentation to the San Diego chapter of the National Restaurant Association. I was asked to write you since I am program chair.

I heard that you made a really good presentation at your local chapter in Los Angeles recently. I think you gave a talk called “Avoiding the Seven Cardinal Sins in Food Service” or something like that. Whatever it was, I'm sure we would like to hear the same or a similar presentation. All restaurant operators are interested in doing what we can to avoid potential problems involving discrimination, safety at work, how we hire people, etc. As you well know, operating a fast-paced restaurant is frustrating—even on a good day. We are all in a gigantic rush from opening the door early in the morning to shutting it again after the last customer has gone. It's a rat race and easy to fall into the trap with food service faults that push a big operation into trouble.

Enclosed please find a list of questions that our members listed. We would like you to talk in the neighborhood of 45 minutes. Our June 10 meeting will be in the Oak Room of the Westin St. Francis Hotel in San Diego and dinner begins at 7 p.m.

How can we get you to come to San Diego? We can only offer you an honorarium of $200, but we would pay for any travel expenses. You can expect a large crowd of restaurateurs who are known for hooting and hollering when they hear good stuff! As you can see, we are a rather informal group. Hope you can join us!

Sincerely,

Consider the following situation as if you were Ian.

Ian was a senior analyst at a major hotel company. Although Ian worked mostly in corporate headquarters, he would occasionally travel to the field where he met with front-line employees and learned what was on their minds.

On a trip to Portland, Ian had the chance to speak with two people working at the front desk about what it was like to work at the hotel. Daniel, the younger of the two had joined the staff recently; Ellen, the other employee (and Daniel’s supervisor), had been with the company for almost 15 years. Both employees seemed particularly interested in talking with Ian because they rarely got a chance to talk directly to anyone from headquarters.

As the three discussed changes in the hospitality industry, Ellen and Daniel complained about their company’s aggressive cost control initiatives, spearheaded by the charismatic but frugal CEO, whose policies were occasionally unpopular. After a few more minutes of conversation, Ellen casually said, “The CEO is so tight with a buck, I wonder if he is Jewish.”

As a Jewish person, Ian did not know how to react. He had never actually experienced anything like this before, especially in a professional setting. Ian’s instinct was not to be combative or hostile, but he felt a bit like a deer caught in the headlights. Daniel looked a little surprised at his supervisor’s remark, but, laughing, he quickly changed the subject. Smiling, Ian made an excuse to end or discussion and walk away.

The next day Ian woke up still bothered by Ellen’s remark. While checking out, he saw Daniel at the front desk. Ian mentioned to him that he may want to tell his supervisor to watch her remarks about other peoples’ ethnicity, to which Daniel replied, “I know what you mean because I am Puerto Rican, but I think that she meant it as a joke.” Ian could see that Daniel just wanted to smooth the issue over.

On the ride to the airport, Ian kept thinking about what he might do. Should he report Ellen to Human Resources? The company had a process in place for such matters, but he was worried. Ian did not know who he was dealing with; maybe Ellen would retaliate if he said something, especially since she would know who filed the complaint. Plus, Ian was not sure what the consequences would be – he didn’t want to get her fired. Ian only wanted Ellen to know how offensive the comments were.

As a team, consider what steps Ian should take.

What are the concerns facing Ian?
