Alexander Tziamalis in 2018 wrote, “One of the first things economics students learn about is Gross Domestic Product (GDP). GDP is also a central concept in many political debates, including Brexit. Will it rise? Will it fall? What effect will this have on our lives? Gross Domestic Product measures the total value of goods produced and services provided in a country, calculating the net value added by each economic “actor”. So if you produce a car sold for £10,000 but you bought parts and materials worth £8,000, then your contribution to the GDP is £2,000. GDP assesses the size of an economy as well as the incomes it generates and the pace at which it grows (or shrinks) over time. A new book by economics journalist David Pilling suggests that in some developing countries GDP has become a national obsession – and with good reason. A nation’s GDP can invite foreign investment, or scare it away. Even in developed economies, a failure to boost GDP yearly can have negative economic and political repercussions. But despite its wide use, there are problems with attaching so much importance to GDP….” Similarly, when it comes to GDP Robert Kennedy in 1968 remarked that it “measures everything in short, except that which makes life worthwhile.” Critically assess the claims by Tziamalis and Kennedy that suggests that placing much emphasis on GDP seems to equally harm human welfare and the world.

Many Ghanaians anxiously, were waiting for the Ghana’s Monetary Policy Committee (MPC) to announce a new Prime rate base on the current economic situation. Last Wednesday, the MPC at a press conference said they have decided to maintain the Prime rate of 18% for the rest of the year. Explain how such an action is expected to affect money supply in the country, holding everything constant? [8 marks]

After 3 months of endurance training John (who you may remember from Applied Essay 3 is not very fit; initial VO2 max of 35.0 mL·kg-1·min-1) could not believe how much further he could run without having to stop. Initially he could barely get around the track once…now he can run 12 laps of the track (3 miles) at a pace he could barely maintain for 1 lap a few months earlier. Although the training likely increased his VO2 max (much of which is explained by central adaptations taking place within his cardiovascular system such as increased stroke volume, etc.) what other perhaps peripheral adaptations have occurred that allow him to operate at a much higher intensity for much longer periods of time?
Not only did John start running but he also started performing a structured resistance training program on his upper body (mainly the bench press). John initially experienced large increases in his upper body strength virtually every time he went to the gym and was overjoyed. However, after 2 months his strength gains began to level out and John became a bit demoralized. He was getting stronger, but at a much, much slower rate. What is the explanation for John’s early strength gains and what has to happen in the longer-term for John to now keep getting stronger? Compare and contrast these two time periods...what causes strength gains in the short-term compared to the long-term? If he continues training long enough will John experience hypertrophy, hyperplasia, or both? Make sure to define these terms.

A relationships researcher (who double majored in English and Psychology as an undergraduate) recalled a well-known phrase from a poem by Alfred, Lord Tenyson, that in the spring, a young person’s fancy turns to thoughts of love. She specifically wanted to test the hypothesis that students are more likely to be distracted by thoughts of romance in the spring than in the fall. She selected a random sample of 12 college students. She measured distractedness via a reaction time test on a computer, where the participants were to press the space bar as soon as they find a target stimulus on the screen that was hidden in a field of distractor stimuli. The software recorded the reaction time elapsed in milliseconds—where longer reaction times indicate more distraction. The researcher held the time in the semester constant by running the participants in the experiment during midterm exams in both the fall and the spring semesters. Was Lord Tenyson’s poem correct?

You have to write an ARM Assembly M4 program for SLTB004A Thunderboard Sense 2.
Write an assembly program that blinks the red LED to send out a SOS Morse code (... --- ...). The dot duration must be 1/4 second and the dash one - 1/2 sec. Duration between dots and dashes is 1/4 second. After displaying SOS the program must delay for 2 seconds and then loop back to blink out SOS again. Use LETIMER for generating all time intervals.
Write an assembly program that controls the brightness of the green RG LED on the demo board. Pressing the BUTTON0 should increase the LED brightness while pressing BUTTON1 should decrease it. Implement 32 grades of brightness. Initial LED duty cycle must be 50%. Use LETIMER for generating PWM and CRYOTIMER for buttons debouncing.
Write an assembly program that first asks the user to enter initial time string in format hh:mm:ss (military time hours:minutes:seconds, 2 digits for each with leading zeros, if needed and colons as separators). After this by pressing BUTTON0 the program should start countdown from this time down to 0 and display valid time. Every press of BUTTON1 should postpone the countdown which can be further continued by pressing BUTTON0 from the time it was stopped before. The program should update time and display it in TeraTerm console window (every time in a new line) with 1 second period. Use RTCC to generate 1-sec events. No button debouncing is required.
Design assembly program that takes two numbers from the user input: n and m with n < m. Then it sets RTCC_CNT register with n and RTCC_CC0_CCV register with m and starts the RTCC. Reaching the alarm moment must be indicated by turning on the red LED.

Suppose that you are a speculator and that you noticed that the Japanese yen (F has depreciated substantially against the U.S. dollar (USD) over the several months. The current spot rate S0.0090 (i.e. 0.0090 USD per Y). Several major financial press articles suggest that the yen will continue to substantially depreciate over the next several months. However, you expect the value of the yen to remain very stable over the next several months (i.e., you expect very little to no volatility). Note that you do not currently have a position in yen; however, if you decide to purchase yen as part of an option strategy, please assume that you will purchase yen at the current spot rate of $0.0090 Your speculative choices are: .Long Call . Short Put Protective Put Covered Call Long Straddle Short Straddle The following options are available for purchase/sale: June 2019 Call: X - S0.0090; C- $0.000206 June 2019 Put: X S0.0090; P $0.000160 June 2019 Put: X = $0.0090; P = $0.000 160 · Given your expectations, which strategy would you choose and why (choose the best answer select the strategy that best aligns with your expectations for the yen)? On the following page, graph the profit diagram (where profit is expressed as USD per¥) for your position, making sure to provide an appropriate title for the graph and label each axis. Please label the corner/kink and break-even value(s) in addition to the minimum/maximum profit (expressed as USD per I) for the strategy. Lastly, calculate your profit (expressed as USD per Y) if the spot rate of the yen at expiration ends up being S0.0093? Ignore trading costs. Writing out the profit function(s) will make everything much easier.
