# ECON240 Final Exam Fall 2019

ECON240 Final Exam Fall 2019 –
Do All Problems (note there are 110 points, you will be graded out of 100)
1) 5 pt Wanda’s will power is 25% in convincing people to vote for her. She needs 50% of
the vote to win. Assuming everyone votes, in order for Wanda to win what percentage of
people must already be planning on voting for her?
2) 10pt Paula wants to help plan for environmental protection for the next hundred
years. Her financial expert is currently using a discount rate of 10% to determine the
present value of several different projects. Relative to today, what must the environment
be worth in 100 years to be counted of equal value ? Discuss how realistic this would be.
What would the discount rate have to be so that so that an environment worth twice as
much as today, would be counted as of equal value?
3) 25pt Take the (correct) answers from problem 4 of Homework 8/9, and answer the
following:
i) Assume M = 500, P
f = 25, Pt = 100, and the person starts with no training: What is
the optimal quantity of food, morsel size, number of bites, training, and savoring factor?
ii) What are the optimal amounts if the person started with 4 hours of training?
iii) Assume that training (when not used) atrophies at 2 units of year. Given the answer
for i) and ii) how much would utility decline after one year of atrophy? Does this change
optimal behavior?
iv) Describe and explain what might be missing from the model used.

4) 40 pt Consider two-person households, which run on the principle each should
experience the same utility from consumption. Let C
1 = Person 1’s consumption, and
C
2 = Person 2’s consumption. They have \$90/day to spend on consumption for the whole
household.
a) Assume the individual’s utility equals how much they consume. Determine how much
each will consume, and what their utility levels will be
b) In this case the first person feels competitive with the second, but the second feels
compersion for the first. Their respective utility functions are as follows:
U
1 (C1,C2) = C1 * ( C1/C2), U2(C1,C2) = C1 * C2
Determine how much each will consume, and what their utility levels will be.
c) Let the household be as if in part b. However, person 1 can increase the second
person’s sense of compersion by giving a small gift that costs k. When they do utility
functions become:
U
1 (C1,C2) = (C1 – k) * [ (C1 – k) / (C2 + k) ] , U2(C1,C2) = (C1 – k)2 * (C2 + k)
Determine the formulas for C
1 and C2. If k = .5, determine how much each consumes
and their utility levels.
d) Describe how the gift changed their relationship and shares of consumption.
e) Assume that a person must consume at least \$5/day to sustain the household. Which of
the above scenarios are sustainable as they are. Are there any where the gift giving
becomes problematic ? What endogenous constraints would be required to make it
sustainable (determine the new consumptions levels and utilities be, can the household
still run by the equal utility principle?)

5) 30 pt Imagine the following: A new social media platform “Space2Pace” has an
architecture where messages are delayed by m minutes before being sent. The sender
can cancel the message within those m minutes. Researchers show that the fraction of
regrettable messages cancelled by users (r) based on the following formula:
r = .10 * m
1/2
the users utility was based on the formula:
U = n – x
2
Where n = number of messages they write an hour ,
x = number of messages they wish they hadn’t sent per hour.
When expressing physically, messages take 1 minute to write, but 50% are regrettable.
When expressing emotionally, messages take 3 minutes to write, and 20% are regrettable
When expressing rationally, messages take 11 minutes to write, and 5% are regrettable
p = probability of message being regrettable, g = number of regrettable messages written
Users can work (or wait) on only one message a time (hint: how are g and x related?)
i) Fill in the following table:

 Mindset m t p n g r x Utility Physical 0 Emotional 0 Rational 0 Physical 1 Emotional 1 Rational 1 Physical 4 Emotional 4 Rational 4 Physical 9 Emotional 9 Rational 9

ii) For each mindset state the optimal available delay time.
iii) For each delay time, state the optimal mindset
iv) Given this information, how would you market “Space2Pace”?
Keep in mind that m =0 implies it is the same as regular email.

# Clinical Field Experience D: Targeted Teaching Activities

Objectives, learning activities, and assessments are all aligned to a standard. It is important to align these components so teaching can be targeted to meet the students’ needs. The data collected from the pre-assessment drives the creation of targeted learning activities. As always, reflection on these practices is a key element in improving practices. Use the data collected from your pre-assessment to determine an appropriate targeted teaching activity to implement during this field experience.

Allocate at least 3 hours in the field to support this field experience.

Prior to teaching your targeted activity, discuss with your mentor teacher your objectives, activities, and assessments. Use any feedback to improve the targeted teaching plan. Implement the targeted teaching activity and related assessment with the same student you have been working with during your field experience. Then debrief the experience with your mentor teacher.

Use any remaining field experience hours to assist the mentor teacher in providing instruction and support to the class.

In a 250-500 word summary, discuss the results of your targeted teaching activity. Describe the conversation you had with your mentor teacher regarding the objectives, activities, and assessments. Reflect and explain how you designed, delivered, and assessed your targeted teaching activity. Indicate how you plan to implement what you learned in your future teaching practice.

APA format is not required, but solid academic writing is expected.

This assignment uses a rubric. Review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

You are required to submit this assignment to LopesWrite.

Document the locations and hours you spend in the field on your Clinical Field Experience Verification Form.

Submit the Clinical Field Experience Verification Form to the LMS in the last topic. Directions for submitting can be found on the College of Education site in the Student Success Center.

(0) Background
Pálinka is a traditional alcoholic beverage produced in Eastern Europe, principally Hungary
and Romania. It is distilled from fermented soft fruits – there is a common saying in Hungary
that, if you can make jam or conserve from it, you can make pálinka with it.
Pálinka International Unlimited (PIU) is a small distillery based in Kent, UK. It was established
eighteen months ago by two entrepreneurs, Erzsébet Nagy and Dacian Iridescu. They had
identified an opportunity to distil and supply pálinka to the sizeable diaspora populations of
Hungarians and Romanians in the UK, on three grounds:
§ The likely Brexit restrictions to be placed on freedom of movement between the
European Union and the UK would make it more difficult for visiting family members to
bring home-distilled pálinka to relatives living in the UK;
§ The likely increase in tariffs accompanying the UK’s exit from the European Union free
attractive;
§ Owing to the undeveloped market for fruit spirits in the UK, much of the soft fruit grown
in Kent below market grade or conserve grade, is simply turned into animal feed or
compost rather than being fermented and distilled.
After eighteen months of trading, the optimism of PIU’s founders about the commercial viability
of a UK-based pálinka distillery has largely been justified. The fruit growers’ co-operatives in
Kent are only too delighted to sell their utility-grade stone fruits to PIU, because they get a
better price from PIU than they would from animal feed manufacturers. The quality of the PIU
product and the efficiency of its distribution channels have won many retail and wholesale
customers.
In fact, sales have increased considerably to the point at which the capacity of the operation
must be increased; specifically:
§ a second pot still was installed and brought on line three weeks ago;
§ a climate-controlled warehouse extension has been built to improve inbound logistics;
§ new marketing channels have been established;
§ new staff members have joined the production team;
§ a new distribution centre is needed to cope with the volume of sales.
Unfortunately, all of these novel developments are causing problems. The day-to-day running
of the PIU operation is handled by Erzsébet, and she has her hands full training the new staff
and supervising production and outbound logistics. Dacian is the salesman and needs to be
on the road visiting account customers and signing new business. They agree that a little extra
investment in operations management consultancy is justified, and they call in your team to
help.

(1) The strange case of Still no.2
Subject: URGENT: fusel alcohols from Still #2
Date: 23 September 2019 at 14:20
Hi all
I am very concerned by some of the readings for fusel alcohols arising from the second
distillations using the new still. As you know, we need SOME fusel alcohols in the
középpárlat [middle cut] for flavour and mouthfeel in the finished spirit, but some of the
readings seem crazy variable by comparison with Still #1.
Still #2 has been running since the beginning of the month, including 4 September when the
gas supply was interrupted by those idiot builders up the road and we had to restart the
burners. I attach the readings for parts per million of amyl alcohol, which as you know should
be between 10ppm and 30ppm.
I know you are busy with packaging inspections, but there are now three of you, so please
could you find time to check whether we need to take further action over this possible quality
issue.
Thanks,
E.

Tunbridge Instruments have finished their analyses of the new infrared thermometers you
have been testing. As you know, we will get a discount on these and the other instruments
for the new climate-controlled warehouse in exchange for testing prototypes 1, 21, 38 and
59.
I attach the results of the Gauge R&R and ANOVA output from their analysis. It looks pretty
good to me. I am out of the office tomorrow but the operations consultants from ARUL will be
here and they can explain the results.

(3) Lean on me (when you’re not strong)
Subject: Making better use of our space!
Date: 23 September 2019 at 19:36
Dear all
While I am away tomorrow the consultants from ARUL will be looking at the efficiency of our
operation in terms of how we use our space and where our equipment is set up, so don’t be
alarmed by strangers with clipboards wandering about.
It occurred to me that, now we have the new still and the climate controlled warehouse
room, we could probably make things more efficient in terms of the way our equipment is
arranged. We can’t move the stills, the chillers, or the mains water supply, but we can move
anything else if we need to.

Please see below for a floorplan of the unit. I have only included the transforming resources
which cannot be physically moved (i.e. the climate-controlled warehouse, the pot stills, and
the mains water supply).

Subject: Cost v benefits – marketing B2B and B2C

To:
Hi Erzsi
I’m just looking at the sales figures for the last seven quarters in comparison with our
marketing spend, and also at the number of visits I’ve made to each wholesaler in
comparison with their average monthly orders. I want to know how effective our marketing
activities have been: overall, and in terms of whether we should focus on B2C or B2B
markets. Eight wholesalers is a lot to manage, you know? Especially given the lower
margins.
Can you ask those eggheads from ARUL to run some kind of analysis?

To:
Lywood, Henry <henry.lywood@bexleysurveyors.co.uk>
Dear Henry
Further to our recent initial discussion about possible sites for our new distribution centre,
for outbound logistics is at a premium in our production facility now that we have added the
second pot still and the climate-controlled warehouse.
Our three most significant wholesalers are all located around the M25, in Rickmansworth,
Cheshunt and Orpington:

MOD006887 International Operations Management. Case materials for Assignment 011, Tri 1 2019-20 10 of 10
The grid location and pallets processed per month for the three existing locations are given
in the table below:

 Facility Cx Cy Pallets/month Rickmansworth 1.5 83.0 45 Cheshunt 63.5 95.0 32 Orpington 80.5 22.0 19

What we need to know as a matter of urgency, is the ideal location for a fourth distributor.
Thanks very much for your initial research and the identification of potential sites in Watford,
South Croydon and Mitcham.
We have some MBA students from ARU London working with us at the moment doing some
operations consultancy; I will ask them if they can work out which of these three potential
sites would be optimal considering the volume of business we are doing at the existing
three.
Kind regards
Erzsébet

# WEEK 4 PSY6802 Assignment: Examine Current Research On Personal And Social Development

Instructions

For this assignment, write an essay about personal and social development in childhood and adolescence related to diverse populations in educational settings. You must review and include at least two peer-reviewed articles that are current (within the last 5 years) to demonstrate current research and thinking in the field of educational psychology.

Be sure to include the following points in your essay:

• What hereditary and environmental factors are likely to contribute to your student’s distinctive personalities during personal and social development?
• How do peer relationships change with age?
• What ways might students act (i.e., behaviors demonstrated) that will benefit others and themselves during personal and social development?

Length: 5-7 pages, not including the title and reference pages

Reference: Include a minimum of three scholarly resources.

Your essay should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to this topic. Your response should reflect graduate-level writing in APA standards. Be sure to adhere to Northcentral University’s Academic Integrity Policy

the differences between auditing public and private companies

You are the general manager of a regional chemical company. In the course of producing your bulk chemicals, large amounts of particles and smoke are emitted through your plant’s smokestack.

· The level of pollutants is below current EPA regulations, and you are violating no laws,

· but neighborhood groups are complaining about minor health problems caused by the smoke.

After investigating numerous alternatives, you find the most effective solution would be to install a “scrubber” system which will remove 90% of the pollutants and ash. Coat =\$1 million. Do you install the system?

Identify three stakeholders and at least two specific ethical considerations or questions for each of the stakeholders you select.

Answer the following questions using the above tables/data:

3/3
1. The database designer included columns for Year and Month in the Sales_Totals table, but forgot to
include a column for Quarter. Write a CASE expression which can be used to return the quarter number
(1, 2, 3, or 4) using other column values from the table.
2. Write a query which will pivot the Sales_Totals data so that there is a column for each of the 4 products
containing the total sales across all months of 2020. It is OK to include the product_id values in your
query, and the results should look as follows:

 tot_sales_large_gears tot_sales_small_gears tot_sales_crankshafts tot_sales_sprockets 6200 5450 0 3050

3. Write a query which retrieves all columns from the Sales_Totals table, along with a column called
sales_rank which assigns a ranking to each row based on the value of the Sales column in descending
order.
4. Write a query which retrieves all columns from the Sales_Totals table, along with a column called
product_sales_rank which assigns a ranking to each row based on the value of the Sales column in
descending order, with a separate set of rankings for each product.
5. Expand on the query from question #4 by adding logic to return only those rows with a
product_sales_rank of 1 or 2.
6. Write a set of SQL statements which will add a row to the Region table for Europe, and then add a row to
the Sales_Total table for the Europe region and the Sprocket product (product_id = 7684) for October 2020,
with a sales total of \$1,500. The statements should be executed as a single unit of work.
7. Write a statement to create a view called Product_Sales_Totals which will group sales data by product
and year. Columns should include product_id, year, product_sales, and gear_sales, which will contain the
total sales for the “Gear – Large” and “Gear Small” products (should be generated by an expression, and it is
OK to use the product_id values in the expression).
8. Write a query to return all sales data for 2020, along with a column showing the percentage of sales for
each product. Columns should include product_id, region_id, month, sales, and pct_product_sales.
9. Write a query to return the year, month, and sales columns, along with a 4th column named
prior_month_sales showing the sales from the prior month. There are only 12 rows in the sales_totals table,
one for each month of 2020, so you will not need to group data or filter/partition on region_id or product_id.
10. If the tables used in this prompt are in the ‘sales’ database, write a query to retrieve the name and type
of each of the columns in the Product table.
