Activity: Take a look at some of the medical adds from the 1900s-1930s.

Select an ad that you find interesting. In at least 200 words, describe why you selected this image and what you think it says about the depiction of medicine in the media. Some things you could write about include: what does this ad indicate to us about its intended audience? What kind of medical claims do they make? What kind of evidence do they provide?

In at least 50 words each, comment on ads selected by two of your peers, noting what you find intriguing or find strange in the image they chose. (30 points)

Instruction: Run a regression of GDP per capita (PPPPGDPlog) on two variables(GFCF and GOV_EXP) at the country level.

Largely due to local economies, the slave experience was diverse in British America. Discuss how slavery evolved differently in the various regions of British America, such as the northern colonies, the Chesapeake region of the South, and the rice kingdom of South Carolina and Georgia in the South.

Kodak Fails to Focus on the Big Picture

The closing case focuses on Kodak and their failure to innovate through the transition from analog to digital technology. It appears Kodak had the resources to innovate and they recognized the coming transition but incorrectly evaluated the needs and desires of the consumer. In addition, members of the company feared change and resisted change efforts. For these reasons, Kodak went from a top 20 Fortune 500 company to bankruptcy in 2012.

Management Update: There are signs Kodak may survive. During bankruptcy, Kodak put Eastman Park up for sale. Eastman Park is a giant industrial complex built in the early 1900s to meet demand for the company’s photographic and film products. In 2015, the company took the park off the market and turned it into a separate company division. With a focus on clean technology, over 60 companies have key operations on the site.

Case Question: Explain how – theoretically, anyway – making “change innovations” in each of the following Areas of Organizational Change might have helped Kodak ease the severity of the conditions that led it to bankruptcy and the challenges facing it now that it’s emerged from bankruptcy:  changing organization structure and design, changing people and attitudes, and changing processes.

Billboards Not Pleasant, but Affective

1. In terms of “any billboard” – not just digital billboards – are they “sky trash” as Scenic America suggests, or do they provide a value to consumers and advertisers as the Outdoor Advertising Association of America asserts? As someone who is already agitated by the constant influx of advertisements in everyday life, I have to agree with Scenic America that they clutter the landscape and natural beauty of the American countryside. While I do not enjoy them, this is not to say that they are not affective. I think that billboards may have had more value in previous decades (especially after they were standardized in the early 1900s.) Even now, however, they are useful in highlighting local amenities and small businesses that may otherwise go unnoticed to highway motorists. I would also like to discuss my distaste for billboards in terms of who they benefit. I agree with Scenic America's assertion that billboards make a few people a lot of money (even though many of their other claims are questionably bias.) Many billboards are monopolized by large corporations that do little to benefit the communities in which they advertise.

2. Should private property owners be allowed to contract with outdoor advertising companies for the placement of billboards on private property without government interference? Or, should the government regulate the number, placement, and size of billboards irrespective of the rights of property owners? This is a difficult argument to navigate, seeing as many people that live in the areas that would accommodate billboards often (but not always) strongly dislike or are hesitant about any government interference. I am certainly not a fan of billboards that display obscene or hurtful messages (like some radical Christian groups are privy to advertise), but I cannot imagine it would be easy to regulate variables like the number, placement and size of billboards on private property. Molly Webb of Curbed Philadelphia states in her article that of the 183 billboards along I-95 in Philadelphia, about half of them violate basic zoning regulations. I think that the first thing to do would be to regulate the number of billboards allowed on one privately-owned property.

3. Have you ever been distracted by a digital billboard? Based on all of your research, do digital billboards pose a safety risk or not? Be sure to defend your answer. Upon my own reflection, I believed that I spent just a bit more time paying attention to digital billboards than static ones (perhaps waiting to see what the digital boards change to.) This hypothesis was confirmed by the National Highway Traffic Safety Administration, which found that eyes glanced at digital billboards for an average of .379 seconds, rather than the .335 seconds spent glancing at static billboards. However, both statistics fall far below the two-second benchmark constituting a hazard. For this reason, I do not believe that digital billboards pose a safety risk, especially when compared to distracted driving caused by cellphone use or alcohol.

Calculating Gross Profit Margin and Inventory Turnover
The following table presents sales revenue, cost of goods sold, and inventory amounts for three retailers of fine jewelry, Tiffany & Co., Zale Corporation, and Blue Nile, Inc. (an Internet retailer).

a. Compute the gross profit margin (GPM) for each of these companies for 2013 and 2012.
Note: Round GPM answers to one decimal place (ex: 0.2345 = 23.5%).

b. Compute the inventory turnover ratio and the average inventory days outstanding for 2013 for each company.

Do not round until your final answer.

Round inventory turnover to one decimal place. Round average inventory days outstanding to nearest whole number.

By mid 1900s black footed ferrets had declined to virutal extinction because their primary prey (prairie dogs > 95% of the diet of these ferrets) has disappeared (due to disease and hunting). Starting >30 years ago, the ferrets were reintroduced to a series of sites int he nrothern US where prairie dog populations were restored to natural levels. Betty Biologist is assigned the task of understanding population dynamics at several of the reintroduction sites. Below is a summary of the sites of reintroduction she is monitoring -- they include two "new ferret reintroduction sites" just about 10 years old (where prairie dogs are now hyperabundant ) and two "old ferret reintroduction sites" where prairie dog populations are at much lower densities (approximating historical abundances).

Betty conducts a snapshot census in one of her sites. She finds the following information: there are 500 new females in the cohort, 200 1 year old individuals, 150 2 year old individuals, 100 3 year old individuals, 50 4 year old individuals and no individuals older than 4. What survival profile do ferrets in this site have? She also learns that ferrets can't reproduce in their first year of life, but otherwise at this site have constant birth rates (consistent with the average rates she found in literature, described above).

A. Calculate gross and net reproductive rates and explain the difference in words

B. If the total population in plot B is now 1000 ferrets, how many ferrets would you expect in the old site in 10 years? Why?

MAT 204 Discrete Structures – Assignment #10

Number theory is the branch of mathematics concerned with the integers. Traditionally, number theory was a pure branch of mathematics – known for its abstract nature rather than its applications. The great English mathematician, G.H. Hardy (1877 – 1947), used number theory as an example of a beautiful, but impractical, branch of mathematics. However, in the late 1900s, number theory became extremely useful in cryptosystems – systems used for secure communications.

Find the following for each pair of integers:

(a) The prime factorization;

(b) The greatest common divisor;

(c) The least common multiple;

(d) Verify that gcd (m, n) * lcm(m, n) = mn.

(i) 315, 825

(ii) 2091, 4807
