What Is the What

...Hayley Van Pelt English 1022.10 Amy Fladeboe September 26, 2014 The Importance of Setting in “What is the What” The setting of What is the What, a story by Dave Eggers, takes place roughly between the 1980s and 2000s. The first sentence at the beginning of the book, Valentino Achak Deng, the central narrator, says “What is the What is the soulful account of my life…” (Eggers xiii). Describing this book perfectly in one sentence. Valentino was born in southern Sudan in the village of Marial Bai. He fled in the late 1980s during the second Sudanese civil war, when his village was destroyed by murahaleen. Valentino spent nine years in Ethiopian and Kenyan refugee camps where he worked as a social advocate. In 2001 he resettled in Atlanta. This book shows symbolism, mood and a theme of how humans struggle to survive throughout Valentino’s life altering journey from where he came from to where he is now. Valentino stayed in Pinyudo, a refugee camp in Ethiopia, where he learned to read and write for three years. During his time spent in the camp, Valentino also had to do manual labor, farm work and other chores. Valentino was told to go into the forest to gather some kindling one day. The forest is frequently a symbol for death, danger or the unknown. “No one wanted to enter the forest, for in the forest, boys disappeared. The first two who died were well known for having been devoured by lions, and thus hunting in the forest for building materials became a job everyone chose to avoid”...

...drawers properly... for the fruits and veggies' sake! How Do the Drawers Work? Most humidity drawers are adjustable with a few clicks between low and high. These settings simply open or close a window in the drawer. For the low humidity setting the window is completely open; for the high humidity setting it is completely closed. What Should Go In Each Drawer? The general rule of thumb is to put things that tend to rot in a drawer with a low humidity setting. This includes fruits and veggies that emit an ethylene gas, like apples and pears, because leaving the window open on the drawer gives those gases a chance to escape. When the gases are released, it helps keep the fruits and vegetables from rotting prematurely. Things that wilt go in the high humidity drawer. This will be all your leafy greens like arugula, spinach, and herbs. By having the window closed, water vapor is held in the drawer and the moisture keeps the greens crisper and fresher longer. Keeping fruits and vegetables that are sensitive to ethylene gas, like strawberries, in this drawer will also keep them away from ethylene producers. Here's a handy list of what common fruits and vegetables should be kept in each...

WorldCom-CEO Ebbers underreported line costs by capitalizing rather than expensing. The internal auditing department found $3.8 million in fraud. Level 1: Is the action legal? If the action is illegal, then it is unethical. Level 2: Is the action fair to all involved? Your behavior should be fair to all parties involved. Note that the concept of fairness does not mean that everyone is happy with the outcome. It only means that the decision has been made in an impartial and unbiased manner. Level 3: Does the behavior make you feel good? It is understandable that not everyone agrees on what is right and fair. This question gets to the personal aspect because your conscience becomes a consideration. 2) Legitimate power is the power that is given to you by the company. An example of this would be a manager hiring an employee. Coercive power is the power that is derived from your formal position. Reward power is the ability to influence someone with something of value. This is the opposite of coercive since it is rewarding the individual. Connection power is based on using...

What to Be

...What to Be Society`s definition of a non-conformist is a person whose behavior or views do not conform to prevailing ideas or practices. To some people it is easy and simple to not conform to the proper manners of society and to others it doesn’t bother them a bit. In 2014, I could be a non-conformist by ignoring certain procedures of life, even though those certain actions can be seen as rebellion and lead to unasked for consequences. Martin Luther King Jr. fought against racial segregation and Jesus preached against Jewish tradition; both these men are seen as non-conformists by our society and both suffered serious consequences. If I were to become a nonconformist in 2014, I’d most likely do it by ignoring school rules such as not being able to use phones in school and having to ask for permission to leave the classroom with a reasonable excuse. Then at home I could ignore curfew, be irresponsible of my chores and not bother with the dress code set by my parents. But in the end I would have to suffer the consequences and eventually abide by the rules. Maybe these examples are too strong because nowadays everybody does their own thing and in teenagers, non-conformism can be seen as rebellion. In Elissa Karg`s, How To Be A Non-Conformist, she says “nonconformists smile only sardonic and sarcastic smiles.” To a grown adult a sarcastic smile can be seen as disrespectfulness and lower an image of the person. I think that non-conformism only leads to trouble for those that don’t...

...How Much Land Does a Man Need In the short story, "How Much Land Does a Man Need" by Leo Tolstoy, Pahom is a peasant living on a small plot of land. When his wife brags that a peasant's life is safer than having money, because with money comes temptation, Pahom agrees, adding that he would not be "afraid of the devil himself" if he only had more land. He buys more land, but is unhappy for no matter how much more land he gets, he wants more. He becomes greedier and greedier until he loses control of his life and, in the end, loses everything. This story shows us that even if we have enough to get by; the prospect of becoming wealthier is so alluring it can cause us to risk all the good things we already have. At the start, Pahom is a content, hardworking man. Unfortunately, he makes the mistake of thinking that more land would make his life better. Pahom was thinking, "Our only trouble is that we haven't land enough. If I had plenty of land, I shouldn't fear the devil himself!” When an opportunity arises for Pahom to acquire more land, he jumps at the chance, convinced that more would make him happy. He paid off his debts and had plenty of fertile land to grow his crops and raise his cattle, but he was only satisfied for a short while. "Pahom was well-contented and everything would have been right if the neighboring peasants would only not have trespassed on his cornfields and meadows", so even when he had the extra land he wanted. His life was far from perfect. Disputes with...

What If

...What if everyone in the world was exactly alike? What if everyone talked the same, acted the same, listened to the same music, and watched the same T.V. programs? The world would be extremely dull! I believe it’s important to accept people for who they are. Differences are important and they should be respected. For example, many important people throughout history were considered different, such as Thomas Edison, Albert Einstein, Harriet Tubman, Peter Tchaikovsky, and Abraham Lincoln. They did great things, but some people thought they were weird, because they had strong feelings about something. I can relate to these people, because I’ve been in that situation before, many times. It all started in elementary school when I realized that I wasn’t like everyone else. My mom says that I have a tendency of obsessing on certain subjects. Unfortunately, these subjects don’t interest other kids my age and they really don’t interest my teachers. In fact, my kindergarten teacher said she would scream if I mentioned snakes or lizards one more time, while she was teaching the days of the week. I would get in trouble for not paying attention, and the teasing began. In third grade, my teacher informed me that I have Asperger’s Syndrome, and I said, “So what? Do you know that Godzilla’s suit weighs 188 lbs.?: Later, I asked my mom, “What is Asperger’s Syndrome? Am I gonna die?” She said that it’s like having blinders on, and that I can only see one thing at a time, and that...

...What If.. What if I was a superhero? When I am at home and lying in my bed, I sometimes think of how cool it would be if I could be a superhero. I don’t mean a superhero like Batman, who is just a man with a lot of money. When I say superhero, I mean like Superman. If I was a Superhero I could do anything. I wouldn’t need a car. I wouldn’t need anything actually. I could just fly off to Africa for example. But first I would like to talk about what superpowers I would have. My superpowers would be: Superhuman strength, speed, hearing, longevity, stamina and intelligence. I am also invulnerable. I can fly. And I can heal myself. These would be my superpowers. I think that if I were a superhero, I would be more of an antihero. I would be like Hancock in the beginning of the film. If I was in the mood I would save some people, but mostly I would just fly around and maybe kill some terrorists. But I would never listen to the government and their so-called problems. Maybe I would be an alcoholic, and never care about it. I don’t think that I would have any friends actually, because I would be so different from the others. Maybe people would hate me, and maybe they would love me. There would off course be some be some that would understand me because I would be difficult to be the only one. I would be very lonely and sad, but could never die. Maybe it is not a good thing to be a superhero. Maybe it would be better to normal or what is said to be normal. Maybe you...

...Capitalization Rules Capitalization is the writing of a word with its first letter in uppercase and the remaining letters in lowercase. Experienced writers are stingy with capitals. It is best not to use them if there is any doubt. Rule 1. Capitalize the first word of a document and the first word after a period. Rule 2. Capitalize proper nouns—and adjectives derived from proper nouns. Examples: the Golden Gate Bridge the Grand Canyon a Russian song a Shakespearean sonnet a Freudian slip With the passage of time, some words originally derived from proper nouns have taken on a life, and authority, of their own and no longer require capitalization. Examples: herculean (from the ancient-Greek hero Hercules) quixotic (from the hero of the classic novel Don Quixote) draconian (from ancient-Athenian lawgiver Draco) The main function of capitals is to focus attention on particular elements within any group of people, places, or things. We can speak of a lake in the middle of the country, or we can be more specific and say Lake Michigan, which distinguishes it from every other lake on earth. Capitalization Reference List * Brand names * Companies * Days of the week and months of the year * Governmental matters Congress (but congressional), the U.S. Constitution (but constitutional), the Electoral College, Department of Agriculture. Note: Many authorities do not capitalize federal orstate unless it is part of the official title: State Water Resources Control...

With this information we needed to find out if this was a suicide or a homicide? The first thing we wanted to figure out was if he walked of the build by his own free will or did someone force him out of the window? To get this answer we would need to find out the distance that the victim feel, and we had already gotten this from the officers and the time it took him to reach the ground. To do this we put the information that we got from the police which was, that the victim was 35.38 feet from an open window on the 35th floor, on a 320 ft. high rise building into the falling time formula t=h16. So what we did next was insert the numbers in the proper place, so we replaced 320 with h because it is the height in this situation so we ended up with the equation t=32016 solved it and got t= 4.472. We used another equation to find the velocity so we could find out the rate he would fall, and find out where he would land which was v= dt. Next we inserted the solutions of the last equation and this one into the proper places and got the new equation was v= 35.384.472 with the solution as 7.91 ft. /s, his horizontal speed he left the building.

...CHAPTER 2 – REVIEWING FINANCIAL STATEMENTS Questions LG1 1. List and describe the four major financial statements. The four basic financial statements are: 1. The balance sheet reports a firm’s assets, liabilities, and equity at a particular point in time. 2. The income statement shows the total revenues that a firm earns and the total expenses the firm incurs to generate those revenues over a specific period of time—generally one year. 3. The statement of cash flows shows the firm’s cash flows over a given period of time. This statement reports the amounts of cash that the firm generated and distributed during a particular time period. The bottom line on the statement of cash flows―the difference between cash sources and uses―equals the change in cash on the firm’s balance sheet from the previous year’s cash account balance. 4. The statement of retained earnings provides additional details about changes in retained earnings during a reporting period. This financial statement reconciles net income earned during a given period and any cash dividends paid within that period on one side with the change in retained earnings between the beginning and ending of the period on the other side. LG1 2. On which of the four major financial statements (balance sheet, income statement, statement of cash flows, or statement of retained earnings) would you find the following items? a. earnings before taxes - income statement b. net plant and equipment - balance sheet ...
