2. Specialty Packaging Corporation began business on March 1, 2013 by issuing 20,000 shares of common stock. The stock has a $1 par value but sold for $8 per share. At December 31, 2013, the common stock had a market value of $6. On its December 31, 2013 balance sheet, Specialty Packaging would report

3.
treasury stock is closed or no closed？

1. What kind of nuclear units were affected in the Fukushima accident?

2. What are the fission products produced in nuclear reactors like Fukushima and Chernobyl?

3. What happened to the nuclear fuel rods in the units 1-4 at Fukushima? How does this compare to Chernobyl?

4. What happened to the spent fuel rods in these units?

5. Which of the four units do you think is the one that poses the biggest danger (for the next million years)? Give reasons.

6. What is the radiation dosage at the edge of the closed zone today at Chernobyl and how does it compare to the dosage at Fukushima? You should look up the wikipedia entry on Chernobyl Exclusion Zone. A nice account of a trip to Chernobyl is given here: http://www.pureearth.org/blog/virtual-tour-of-chernobyl/. How long do you think that these closed zones will be needed? Give reasons.

Explain why each of the following statements is True, False, or Uncertain according to economic principles. Use diagrams where appropriate. Unsupported answers will receive no marks. It is the explanation that is important.

A6-1. An economy with a recessionary gap will never return to long run equilibrium without policy intervention.

A6-2. In a closed economy, investment will equal the sum of private saving and government saving.

A6-3. An increase in private saving for a closed economy implies lower consumption in long-run equilibrium and also leads to lower GDP growth.

A6-4. You have two Canadian dimes. One is from 1962 and contains 25 cents worth of silver; the other is from 2013 and contains no silver. You would clearly use the later coin when paying for a coffee rather than the earlier one.

A company has stores in different countries. The CEO is not sure about the profitability of three stores. The following table includes the revenues and costs of these three stores in the year ended (in euros) :

Should any of the stores be closed as soon as possible? Choose the appropriate decision for each store on the assumption that closing one store will not affect any other stores and total head office costs would not decrease if any of the stores were closed.

1) Paris

close or continue

2) Vienna

close or continue

3) Dublin

close or continue

An experiment was done to see whether open-book tests make a difference. A calculus class of 48 students agreed to be randomly assigned by the draw of cards to take a quiz either by open-notes or closed-notes. The quiz consisted of 30 integration problems of varying difficulty. Students were to do as many as possible in 30 minutes. The 24 students taking the exam closed-notes got an average of 15 problems correct with a standard deviation of 2.5. The open-notes crowd got an average of 12.5 correct with a standard deviation of 3.5. Assume that the populations are approximately normal. At the 5% significance level, does this data suggest that differences exist in the mean scores between the two methods?

1) Please define the term closed circulatory system. Which animals have it, and what are its’ evolutionary advantages over open systems (why might a closed system be more efficient)?

(10 points)

2) Describe all the events (steps) that occur during a cardiac cycle for mammals (organisms with a

double circulation), as well as the opening and

closing of all heart valves, and the signals arising from the SA and AV nodes. How does this cycle contribute to metabolic homeostasis for our cells, and what is the purpose of the valves?

3) Using information discussed during our lectures thus far, propose 2 physical ways that a human may develop hypertension

(abnormally elevated blood pressure). [One of these mechanisms should

stem from the blood vessels, and the other at the level of the nervous system]. What are the long-

term consequences of elevated hypertension?

Consider a set of n boxes with their positions numbered from 1 to n. Initially all the boxes
are CLOSED. These n boxes are subject to modifications over n iterations as follows. At the ith
iterations the boxes at the positions whose ids are multiples of i are flipped, i.e. changed from
CLOSED to OPEN or vice-versa. For example, at iteration 1, boxes at all positions are
flipped, at iteration 2, boxes at positions 2,4,6,etc. are flipped, at iteration 3, boxes at positions 3,6,9, etc.
are flipped.
Propose an algorithm for find out, that after n such iterations how many boxes will be OPEN.
Note that the answer requires only how many boxes, not their positions. Describe the rationale
for the algorithm, give the pseudocode, and its complexity. Grading scheme: (your grade will be
based on whichever class your algorithm falls in)
- For algorithms with complexity O(kn), where k is the number of digits of n.

Describe computer-assisted coding and lead a discussion of the pros and cons of this technology.
