Research on Madrid 2004 Bombing

In March, 2004, commuter trains in Madrid, Spain were attacked, and terrorism was suspected. Research this incident and prepare a report that describes the following:

Which group or groups were responsible for the attack? Describe how this was investigated.

How did the group carry out the attack? Provide a detailed description of the attack.

Why did the attackers choose this particular target? What did they hope to achieve?

How did investigators identify the attackers? Was anyone punished for the attack?

Conclude your report by explaining whether the group achieved its goal.

Support your responses with examples.

  1. Enter the data above into the tab labeled Apple. Graph the data in Excel and use your graph to determine what kind of time series pattern exist. Put your answer in your spreadsheet.
  2. Make the following forecasts for 2020. For all of them, use Mean Squared Error to determine which of the forecasts is the best. Make sure your answers are clearly labeled.
    1. Naïve forecast from one prior time period
    2. Calculate a 4-period moving average
    3. Calculate a 3-period moving average with the following weights for time t: time period t-1=0.8, t-2 = 0.15, t-3=.05
  3. In the tab called Apple Smoothing, use the data from 3. to forecast 2020 using an alpha equal to 0.7, 0.8, and 0.9. Using MSE, which one offers the best estimate for 2020?
  4. In the tab called Apple Regression, use the information from 3. and run a regression to determine your forecast for 2020
    1. Put your regression output in F1 of the same workbook.
    2. Calculate what your forecast is for 2020 in F21.
    3. How does well does this regression equation predict revenue? Write your answer in F22. In addition, explain what your numerical answer means in words.

Why did Burberry choose to focus on the value, rarity, and inimitability of its core products centered on outwear, as opposed to the proliferation of unrelated products?

Why was Burberry able to turn around?

Burberry is 160 years old in 2016. Find another firm in any industry and any country that has also survived over 150 years (or at least 100 years). What are the “secrets” behind its longevity?

Some argue that there is no future in made- in-UK textile products. Others suggest iconic UK firms have a special responsibility to create jobs by manufacturing products in the UK. What is your view on this debate?

  1. Explain WHY there is a “curve” or “boundary” associated with these values in the table? Why is there a MAXIMUM boundary or Frontier of Possible Production?
  2. If we draw this curve or boundary APPROXIMATELY to scale, WHAT SHAPE – a straight line, a concave line, or a convex line - would describe the curve AND WHY would this the case?
  3. Why is TECHNOLOGY, T important to an Economy-Wide Productive Potential?
  4. How might an INCREASE in the Productive Potential of ONE GOOD ONLY lead to the ability of the economy to actually INCREASE the actual production of BOTH GOODS?

In the flow around a cylinder, boundary layer separation occurs due to (SELECT CORRECT ANSWER)

energy losses in the boundary layer that prevent it from remaining attached.

the Mach number being too high

the surface being rough

a low buoyancy force.

A boundary layer is

a)

a region of flow close to a surface where viscous effects dominate the physics of the flow.

b)

a region of flow that has high turbulence.

c)

important in providing a slip condition at the wall.

d)

increases the velocity of the flow towards the wall

Two flows may be classified as having dynamic similarity if

a)

both cases have equal drag force

b)

both geometries and key dimensionless parameters (i.e. Reynolds numbers) are the same.

c)

both velocities of the flow are the same.

d)

both cases have identical geometry but different size.
