Fly to minimise delays

/in /by

 
The 2009 ASA Statistical Computing and Graphics Data Expo consisted of flight arrival and departure
details for all commercial flights on major carriers within the USA, from October 1987 to April 2008.
This is a large dataset; there are nearly 120 million records in total, and takes up 1.6 gigabytes of space
compressed and 12 gigabytes when uncompressed. The complete dataset along with supplementary
information and variable descriptions can be downloaded from the Harvard Dataverse at
https://doi.org/10.7910/DVN/HG7NV7
Choose any subset of (at least two) consecutive years and any of the supplementary information
provided by the Harvard Dataverse to answer the following questions using the principles and tools
you have learned in this course:
1. When is the best time of day, day of the week, and time of year to fly to minimise delays?
2. Do older planes suffer more delays?
3. How does the number of people flying between different locations change over time?
4. Can you detect cascading failures as delays in one airport create delays in others?
5. Use the available variables to construct a model that predicts delays.

Response paper on Moonlight

/in /by

1. In the film Moonlight, the urge to fit individuality into the mold of American standardization is explored within self and community as Chiron struggles to be comfortable with his own identity. What does the film express about the ways community, Black culture, and identity are interrelated?
a. CONSIDER: How does this film cultivate a self-image around race and ethnicity? Which scene expresses/explores this? How does it express it–what cinematic/film techniques, including dialogue, create this effect?
b. CONSIDER: How is the urge to fit individuality into the mold of American standardization explored within the self as Chiron struggles to be comfortable with his own identity? How it is explored within the Black culture? How it is explored within the community? Which scene expresses this? How does it express this? What cinematic/film techniques, including dialogue, create this effect?

The Interaction between Physical Exercise and Appetite

/in /by

1. How does exercise, both acutely and chronically, affect appetite, appetite-related hormones and energy intake? What direction are any changes in response to exercise?
2. How does exercise influence central (brain) appetite responses using functional MRI?
3. Can you develop a research idea / study design that you would like to investigate during a PhD that relates to the background information and gaps you have identified? What question do you want to address? Will this be an acute or chronic study? What exercise protocol or physical activity exposure will you use? What measures will you include? Who will you recruit?

Effects of Trade Policies and Tariffs

/in /by

 
 
Whether you agree or disagree and whether or not they provide helpful information to the following discussion: Some politicians, labor unions, and special interest groups argue that US trade deficits are harmful to the economy and nations that run large trade surpluses with the US are benefiting from unfair trade practic​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​es and agreements. These parties support increasing tariffs on imports, elimination, or re-writing of trade agreements. Respond to the following in a minimum of 175 words: Discuss what credible economists say about the effects that tariffs, changing trade agreements, and/or manipulating exchange rates will have on the total US trade balance. Do you agree with their assertions? Why or why not​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​?
