Answer the following two questions. (1) Make comparisons of how Paul Laurence Dunbar's poem "We Wear the Mask" and Cia Verschelden's "We Wear the Mask Revisited" depict the Black experience in America. Are the depictions accurate in your opinion? Compare the two and explain. (2) Dunbar's poem was originally published in 1895 and Verschelden's revisited version is from 2020. Discuss why you think the two pieces could continue to have similar symbolism, and how Blackness is navigated in White society.
Let M denote the message space, K the key space, and C the ciphertext space of a private-key encryption scheme. Define the set of 2-bit strings S := {00, 01, 10}. Consider the following variants of the One-Time Pad (OTP) encryption scheme. (a) The key space is K = {0,1}^(2l) and the key generation algorithm chooses k in K uniformly. The message space is M = S^l, i.e., a restricted set of 2l-bit strings. Encryption works as in the One-Time Pad: Enc_k(m) = k XOR m for k in K and m in M, and decryption works as in the One-Time Pad: Dec_k(c) = k XOR c. (b) The key space is K = S^l and the key generation algorithm chooses k in K uniformly. The message space is also M = S^l. Encryption and decryption work as in the One-Time Pad. For each of the above encryption schemes, state whether or not the scheme satisfies the condition of perfect secrecy, and prove your answer.
You are free to use any programming language, as well as any built-in implementation of a Gomory-Hu tree. A random graph G(n, p) is a graph in which each edge occurs independently with probability p. (a) Prove that G(n, p) for p = 5 log n / n is connected with probability at least 1 - 1/n. (Hint: perform a separate analysis for all partitions of size (i, n - i), i in [1, n/2].) (b) Argue that with probability at least 1 - 1/n, the Gomory-Hu tree of G(n, p) for p = Theta(k log n)/n has all edges of weight k or more. (c) Perform an experimental analysis of the k-edge-connected components in G(n, p), for a large collection of choices for k and p and an appropriately large integer n, to estimate: the size of the largest k-edge-connected component; the number of k-edge-connected components; and the inflection point(s) for the probability p around which the number of k-edge-connected components seems to change by a large value.
Research the Internet to find definitions of the following leadership terms: Aikido, SMART, Delphi analysis, SWOT analysis, STAR, and the GROW approach. Research the definitions and their differences. Choose an example of a decision that did not bring the expected benefits to the organization described, based on this research. Briefly summarize the wrong decision and its consequences, and present an alternative while describing the new decision-making process and listing possible positive outcomes. Write an essay about your analysis, and include the 6 definitions of the above terms you have researched with a brief summary of the differences. Cite sources in APA style.
The Phillips curve represents the relationship between unemployment and inflation. If the unemployment rate in the economy is steady at 4 percent per year, how does the short-run Phillips curve predict that the inflation rate will be changing, if at all? What will happen if the unemployment rate now rises to 7 percent per year? Assume there are no changes to inflation expectations. Provide an appropriate graph to support your discussion. Cite any sources in APA style.
In this assignment, you will apply your knowledge of how banks create money. Suppose the required reserve ratio is 10 percent and you withdraw $25,000 from a bank. What is the deposit multiplier? What is the total decrease in deposits in the banking system? What is the change in the money supply? Explain each answer in detail, with clear and organized writing, and cite 3 sources in APA style.
Aggregate demand has four components: consumption spending (C), investment spending (I), government spending (G), and net exports (NX), where net exports equal spending on exports (X) minus imports (M). Describe the relative importance of these four components in regard to China, as well as some factors that may affect them. Cite sources in APA style.
One practical limitation of Keynesian economics is the challenge of implementing active economic policy quickly. One practical limitation of the Classical or Neoclassical model is that it suggests allowing the economy to self-correct in the long run, but recessions may last a very long time. For each limitation, discuss how severe you think the problem is. Explain, and provide an example. Cite sources in APA style.
Economic activity in developing countries is limited, at least in part, due to limited investment. Investment is limited mostly due to insufficient lending. Lending is mostly limited due to economic uncertainty and the prospect of unexpected inflation. In light of this, please describe how a lender can lose during inflation if the inflation is unanticipated and the loan is a fixed-interest-rate loan. How would a variable-interest-rate loan (one that adjusts over the contract period) eliminate these losses? Cite sources in APA style.
Explain why one would rather be a borrower during a period of unexpected rising inflation, and a lender during a period of unexpected declining inflation. Cite any sources in APA style.
