Select a topic which allows you to inform your audience of a significant aspect of a culture that is
different than your own. Possible topics include social customs, family traditions, holidays, clothing,
food, religious traditions, and sporting activities. Refer to Chapter 7 of your text as a guide.
Research your topic. Be imaginative in choosing content for your speech. It is not enough to simply
summarize basic information from the Internet about a country or culture. Narrow the topic by selecting
one specific aspect on which to focus your ideas.
Organize the main points of your speech using an informative pattern of organization. Your speech
should give your audience a deeper understanding of your topic, but should not be designed to affect
your audience’s beliefs, attitudes, or behavior.
Provide adequate support for each main point by citing at least three credible sources in the speech.
Incorporate examples, narratives, testimonial evidence, statistics, analogies, explanations, and/or
definitions where appropriate. Sources must be cited orally in the speech. If you have had direct contact
with a different culture, you should supplement your research with your personal experience.
Create an introduction and conclusion.
Once you have thought through each part of the speech (introduction, body, & conclusion), create a
rough draft outline of the speech.
Create speaking notes to use during your delivery. Use key words and phrases rather than complete
sentences. Your notes should serve only as a memory aid and should not be a word-for-word manuscript
of your speech.

ECON 570 Problem Set 1

1 Cholesky Factorization
A. Recall that if A ∈ R
n×n
is symmetric and positive definite, then it can be factored as
A = LL′
, (1)
where L is lower triangular and nonsingular.
Assume that A is 2 × 2. Write down the system of equations implied by (1) and
calculate the number of flops required to perform the Cholesky factorization in this
case.
B. Extend the previous result and show that the complexity of the Cholesky factorization
for the general case of a n × n matrix is O(n
3
).
2 Computational Complexity
A. Write custom functions for
1. Calculating the inner product of two vectors.
2. Calcuatling the product of two matrices.
B. Generate random m × n matrix X and n × p matrix Y , for m = 50, n = 100, p = 200.

Compute
1. The amount of time it takes to multiply X and Y using the custom code you
wrote.
2. The amount of time it takes to multiply X and Y using built-in NumPy methods.

C. Now increase m, n, p each by a factor of 10.
1. How long do you expect it would take to multiply X and Y using your custom
code? How long does it actually take?
2. How long do you expect it would take to multiply X and Y using built-in NumPy
methods? How long does it actually take?
D. Increase m, n, p each by a factor of 10 again, and repeat the above but using NumPy’s
built-in methods only. How long does it take to multiply X and Y ? Did it increase by
the same factor as it did before when all the dimensions were increased by a factor of
10? Why or why not?
E. Generate a n × p matrix and a n-vector y.
1. Set n = 5000, p = 200. How long does it take to regress y on X?
2. Set n = 50000, p = 200. How long do you expect the same regression would take?
How long does it actually take?
3. Set n = 5000, p = 2000. How long do you expect the same regression would take?
How long does it actually take?

• What was the original intent for redistricting the specified area in the first place?

• Was the redrawn district representative of the original intent and what have the courts had to say about this issue?

• As a citizen or resident of Texas, what do you think of the politicizing of districts in an effort to garner votes from specific types of people (race, ethnicity, gender, political party affiliation, etc)?

• What are your over all thoughts and impressions about this issue? Should the politicians be taken completely out of the redistricting procedure, in an effort to maintain a bit more fairness or is the current system working? Why or why not?

1.Who to interview?

Select someone in whom you are genuinely

interested in learning more about their past or current job. Make sure

you able to set up a time to interview this person.

If you are reaching out to a person you found online or

someone you don’t know via email, make sure to write a professional,

polite email (err on the side of formality).

5.Take notes as carefully as you can

, and then, if you haven’t recorded,

make sure to type up or rewrite a fuller version of your notes the

1. The intrinsic value of nature is more important to consider than its utilitarian value when developing sustainable management plans.

2. Traditional ecological knowledge should take precedence over scientific evidence in developing ecosystem management frameworks.

3. Human advancement cannot occur without adversely affecting the natural environment and attempting to balance ecosystem needs with human resource needs is futile.

4. Prioritizing technological innovation is the best way to ensure that we can reverse damage to ecosystems and sustain future generations.

You must design a database file with tables & fields, relationships, and queries as given below. Please submit your Access file without any data – the TAs will import a standard batch of data to evaluate your work. However, you may find it useful to temporarily add some data to your tables, especially to test your queries and reports.

1) Tables: Fields (keys in yellow, foreign keys in blue, both key & foreign key in green)

• Supplier: SupId (Number), LastName (short text, field size 30), FirstName (short text, field size 30), Email (Short Text, field size 30), PrimaryPhone (Short Text with 000-000-0000 input mask)

• Distributor: DistId (Number), LastName (short text, field size 30), FirstName (short text, field size 30), Supplier (Number), Email (Short Text, field size 30), PrimaryPhone (short text with 000-000-0000 input mask)

• Customer: CustId (Number), Name (short text, field size 30), UserId (short text), Password(short text, field size 30), PrimaryPhone (short text with 000-000-0000 input mask), StreetAddress (short text), ZipCode (Number with 00000 input mask)

• Item: UPC (AutoNumber), Name (short text, field size 50), Supplier (Number), UnitPrice (Number)

• Transaction: InvoiceNumber (AutoNumber), Supplier (Number), Distributor (Number), Customer (Number), Date (Date/Time with Short Date format), Amount (Number)

• TransactionElement (note that this table’s key is two fields): Item (Number), InvoiceNumber (Number), Quantity (Number), Amount (Number), Sent (yes/no, default value: no), Paid (yes/no, default value: no).

2) Relationships: Link all foreign key fields to their original tables

• Supplier, Item.Supplier, and Transaction.Supplier to Supplier.SupId

• Distributor to Distributor.DistId

• Customer to Customer.CustId

• InvoiceNumber to Transaction.InvoiceNumber

• Item to Item.UPC

3) Queries:

• Select all Transactions where Supplier.SupId = 509

Part 1: Stockholders and Management Interests

Stockholders and managers want the same thing, don’t they? Theoretically, yes, but in reality, it does not always work that way. Too often, managers’ personal goals compete with shareholder wealth maximization. Sometimes, managers pay themselves excessive salaries or bonuses that are at odds with the idea of shareholder wealth maximization. How many times have you seen in the news examples of CEO excesses or outlandish spending on events or things that definitely do not help the overall goal of stockholder wealth maximization?

To prepare for this Discussion, think about a time in your professional experience when a decision was made that seemed to benefit a specific manager or small group of managers and not the overall corporation. If you do not have professional experience directly related to this topic, research a situation in the news where this theme is demonstrated. Consider the outcomes of such an imbalance between manager and stockholder interests and research on how to avoid such a situation.

Describe the situation from either your professional experience or your research.

Explain two or more motivational tools that can aid in aligning stockholder and management interests.

Explain how your selected tools are effective in resolving potential conflicts among managers and stockholders.

Support your discussion with appropriate academically reviewed articles. Use APA format throughout.

Part 2: Application of Concepts/Time Value of Money

Review the video links below. Based on the materials presented in these videos, discuss how you will use the time value of money concepts in managerial decision making. Be specific and give examples based on your experience or research.
