WIKIPEDIA, leverages technological innovation afforded by the Internet combined with a crowdsourcing approach to content development and maintenance. Beyond the technical challenges of web interfaces, servers, and bandwidth for delivery is a sometimes-overlooked capability: the Wikipedians themselves. Over 32 million people have registered accounts to contribute edits to Wikipedia. More than 300,000 users provide edits to the website at least once a month. These volunteers build the content for the site, using a creative commons license that ensures free access to any of the 500 million unique visitors each month. This crowdsourcing and its legal underpinnings are successful only as long as individuals are willing to spend their own time contributing to the site for no pay or other extrinsic benefits. The ability to attract and utilize legions of interested individuals is vital to the success of Wikipedia both today and into the future. Moreover, Wikipedia is a nonprofit, free-of-advertising social entrepreneurship venture that is exclusively financed by donations. Wikipedia runs regular calls for donations using slogans such as: “Please help us feed the servers,” “We make the Internet not suck. Help us out,” and “We are free, our bandwidth isn’t!” Calls for donations also come in the form of personal appeals by co-founder Jimmy Wales. The question arises whether the donation model is sustainable given not only the increasing demand for Wikipedia’s services, but also the emergence of competitors. Wikipedia might not be as error-prone in science topics as shown in the Nature study mentioned earlier, because most entries on Wikipedia are not about science. Wikipedia maintains that it fosters a “neutral point of view.” A recent research study tested this claim. In particular, a study of 28,000 articles about US politics revealed a significant bias. On average, Wikipedia entries lean left of center. Initial entries arrive with a slant, and change little over time. This bias is more pronounced in earlier Wikipedia articles. The authors call this the “vintage bias.” Although the degree of slant in Wikipedia articles changes little over time, more recent political entries are more balanced. One reason the authors put forth to explain the vintage effect is that in the early days of Wikipedia only technology enthusiasts and early adopters participated, and this demographic tends to lean left. The shift toward a more “neutral point of view” over the years has arisen from the growth of Wikipedia, bringing in the early and late majority as contributors. Questions

a. How can Wikipedia maintain and grow its ability to harness the crowdsourcing of its “Wikipedians” to maintain high-quality (and quickly updated) content?

b. As Wikipedia keeps growing, do you think it can continue to rely exclusively on donations (in time and money)? Why or why not? What other “business models” could be considered? Would any of those “violate the spirit of Wikipedia”? Why or why not?

c. What, if anything, should Wikipedia do to ensure that its articles indeed present a “neutral point of view”? Shouldn’t the crowdsourcing approach ensure objectivity? Does a “neutral point of view” matter to Wikipedia’s sustainability? Why or why not?

d. How has the “long tail” affected Wikipedia?

A flying wing has a planform area of 3700 ft², a root chord at the airplane centerline of 34 ft, an overall taper ratio of 0.275, and a span of 170 ft. The average weighted airfoil thickness ratio is 10.2% and the wing has 36 degrees of sweepback at the 25% chordline. The air- plane is cruising at a pressure altitude of 17,000 ft on a standard day with a wing loading of 40 lb/ft². The cruise Mach number is 0.30. Determine the following:

(a) skin-friction drag coefficient (assume a spray-painted surface)

(b) pressure drag coefficient

(c) induced drag coefficient

(d) total drag coefficient

(e) total drag in pounds

Remember that a wing has both upper and lower surfaces exposed to the flow. Use the appropriate skin friction coefficient equation (Chp 4) that would include transition from laminar to turbulent; assume Re,trans = 500,000. If the surface is fully-rough, then consult 5.20 on pg 266. Form drag is based on the fineness ratio charts. The Oswald efficiency factor is high for wings—assume e = 0.95.

I am a travel agent, I book in-city ride tickets and also ship your luggage to the next destination. 1-NYC All Around Town it is $29.00 2-Big Bus NYC Tour it is $49.00 3-NYC one day guided Sightseeing Tour it is $89.00 4-Circle Line Complete Manhattan Island Cruise is $44.00 5-Viator VIP: Empire State Building, Statue of Liberty and 9/11 Memorial is $129.00 I also provide a quote for your shipment to be mailed to your next destination. In order to calculate our quote, we need to know the total weight of the shipment in pounds, the distance in miles and whether or not there are hazardous materials in the shipment (e.g. batteries). The calculation for the quote is as follows: Quote = .65 * # of miles + .83 * # of pounds If there is hazardous materials in the shipment, there is an extra cost of .20 * # of pounds If the distance for the delivery is less than 150 miles and the total weight for the shipment is greater than 500 pounds, then there should be a 10% discount off of the total quote.
