u.s justified in dropping atomic bomb Essays

u.s justified in dropping atomic bomb Essays u.s justified in dropping atomic bomb Essay u.s justified in dropping atomic bomb Essay Many people today could argue their side and reasons on why they think the United States was Justified in bombing Japan. But was Osama in Laden Justified in orchestrating 9/11? No one in their right mind would support the killing of innocent civilians on 9/1 1 on the basis of the argument that Osama Bin Laden and his cohort wanted to end the war between radical Islam and the U. S. So why is it acceptable for the U. S. to have incinerated tens of thousands of civilian men, women, children and babies to end the War, when there was a military alternative? The U. S. ould have ontinued the war against the Japanese armed forces instead of targeting Japanese civilians. If the Japanese civilians who were killed are not deemed to have been innocent because they may have supported the Imperialist Japanese Government, then neither was those who died in the World Trade Center or any Americans, because they support the U. S. Government! Yes, the Japanese did bomb the U. S first but didnt more than half of the America people tell them they werent right for doing it on pearl harbor ? So if their wrong, what makes it okay for the United States? The United states was mad because Japan came to their land and killed their innocent people and destroyed everything that they worked so hard to form, but now its suddenly not okay for Japan to be Just as upset? Its not even about who wanted the war to end and who was going to do what! Was killing thousands of innocent women, and children, really worth the satisfaction of being able to say you won? okay sure Japan did awful things, but America lowered themselves to a incredibly low level with this evil action. And were in no way right for their actions at all.

Top 5 Review Activities for Elementary Students

Top 5 Review Activities for Elementary Students Review sessions are inevitable in the classroom, and for many teachers, it can be a rather uninspiring exercise. Too often,  review activities feel boring and may leave your students feeling unengaged. But, it doesnt have to be that way. By choosing some fun and engaging activities, a traditionally mundane review session can become an active and inspiring session. Check out these five teacher-tested review lessons with your students. Graffiti Wall When students here the words its review time, you might get a bunch of groans. But, by turning the review session into a hands-on activity, students will be more likely to enjoy the exercise and even better retain the information.   Heres how it works: Place a variety of different colored dry erase markers on the front board(or different colored chalk if you have a chalkboard).Then give students a review topic, and randomly call about three to five students at a time to the board.The students goal is to think of any word that associates with the given topic.Students can write the word any way they like (sideways, up and down, backward, etc.)One rule you must enforce is that students cannot repeat any word that is on the board.Once all the students have had a turn, pair them up and have each student tell their partner about five of the words on the board.View pictures and learn more about this great  graffiti wall review activity  here. 3-2-1 Strategy The 3-2-1 review strategy is a great way for students to review just about anything in an easy and simple format. There are a few ways you can use this strategy, but often, the preferred way is to draw a pyramid. Heres how it works: Students are given a review topic and told to draw a pyramid in their notebook.Their goal is to write down three things they learned, two things they thought was interesting, and one question they still have. You can adapt this activity any way you want. Instead of asking a question on the top of the pyramid, students can write a summary sentence. Or, instead of writing two things they found interesting, they can write two vocabulary words. It is very easily adaptable.  View a picture of the 3-2-1  review pyramid. Post-It Practice If your students love the game Headbands, then they will love playing this review game. Heres what you have to do to get started. Provide each student with a Post-it note, and have them write down one review term on it.Then without the other students seeing the note, have each student choose one person to stick their note to their forehead.The goal of this activity is for students to go around the room and try to explain the term without using the actual term.Make sure that each student has the opportunity to go around the room and explain each term. Move Ahead of the Class This review game is the perfect way to incorporate teamwork while reviewing important skills. Here is how you play: Divide students into teams of two, then have students stand in a row where one student is behind one other.Use the squares of the floor as the game board and tape off a finish line.To play the game, have one person from each team face-off by answering a review question. The first person to answer it correctly moves ahead to the next square.​After the first question, the next person in line takes the place of the student who got the answer correct.The game goes on until one team crosses the finish line. Sink or Swim Sink or Swim is a fun review game that will have your students working together as a team in order to win the game. Heres what you need to know to play the game: Divide students into two teams and have them form a line and face one another.Then ask team 1 a question, and if they get it right, they can choose one person from the other team to sink.Then ask team 2 a question, and if they get the answer right, they may either sink their opponents team member or save their sunken team member.The winning team is the one with the most people at the end.

Distinction is emphasized between staff and employees on one hand, and local volunteers on the other. Volunteers are accorded guest status, i.e. with some privileges. The XYZ Ecotourism aims to provide outdoor recreation site for local residents and tourists with amenities for picnicking, hiking, bush walking, and other similar outdoor activities. It encourages weekend recreation/retreat for local residents and tourists who temporarily seek refuge from the hassles of urban life. XYZ Ecotourism was conceived some months ago during a group outdoor get-together by well-minded individuals, businessmen with previous acquaintances, who saw a flourishing ecotourism business in Albury, New South Wales, Australia. They were also impressed by the concern of local residents in the area who took turns in caring for their environment, and promoting green tourism among local businesses and small entrepreneurs in the community. With firm determination, the businessmen - five in number - who now comprise the majority of the stockholders bonded together and slowly transformed the once uninhabited and underdeveloped area in the outskirts into a flourishing ecotourism destination to feature an outdoor recreation in a natural setting. The recreation site provides a venue for people to escape - i.e. temporarily - from the rigors and stress of urban life, and to engage in a predominant recreational pastime of picnicking in a natural setting with the amenities of modern facilities and new technology. The site also provides a peaceful retreat for passive pursuits as well as opportunity for more active endeavors such as jogging, walking, hiking, bush walking, etc. 3. Summary of Objectives and Timelines 3.1 To provide an outdoor recreation or an ecotourism destination, conveniently situated near urban centers in Alsbury, New South Wales; 3.2 To produce an approximate number of picnic areas, with parking spaces, roads, paths, most of which are still to be constructed.

Demographics and Culture of Brazil Essay Example for Free

Demographics and Culture of Brazil Essay Brazil is currently enjoying the number 5 spot as far as big populations in the world are concerned with 190,010,647 people recorded as of August 16, 2007 (C.I.A., 2007, par. 7).

This clearly illustrates that in just forty years, the population of Brazil has already doubled its number of natives.   With a land area of 8,456,510 square kilometers, Brazil has around 58.2 people per square mile. It was estimated by the Population Reference Bureau that 81% of the population lived in urban areas in 2001, up from 66% in 1980 (Brazil Population, 2007, par. 2).

The World Fact Book 2007 Brazil’s culture is very much influenced by their Portuguese invaders who have ruled the lands for three centuries.   It was only in 1822 when Brazil finally became a nation. Although Brazil is a democratic country, education, health, safety (physical and juridical) are deficient in Brazil (Brazil Travel, n.d., par. 1). Brazil is the leading economic power and regional leader in South America yet uneven distribution of income is a pressing problem (C.I.A.).   Its economic strength is dependent on its mining, agricultural and manufacturing industries. One of Brazil’s cultural attractions is the Carnaval or Mar de Gras which is annually celebrated at Rio de Janeiro.   The origins of this celebration dates back to the ancient Greek festival in honor of Dionysus which the Romans soon adopted for the Roman God Bacchus as the feast of Saturnalia (World Music Productions, 2007, par. 1).   Back then they celebrated it by making slaves and their masters exchange clothes while drinking wine for the whole day. Saturnalia was converted by Roman Catholics into a festival leading up to Ash Wednesday or before the 40 days of sacrifices prior to Easter.   It became known as Carne Vale which literally means farewell to the flesh and is a fiesta filled with every known sin the Brazilians could think of.   Carnaval, as spelled in Portuguese, is a 4-day celebration. It starts on Saturday, and ends on Fat Tuesday, or Mardi-Gras. (All About Rio, 2007, par. 1). One of the major issues that had put a spotlight on Brazil in the recent years is regarding its environment.   The very rich Amazon forest is the habitat of many endangered species and it plays a major role in the weather cycle of the world.   If it continues to be cut down, global warming will greatly be affected because the Amazon Forest is one of the world’s best source of rain.   Other problems include illegal wildlife trade, air and water pollution in Rio de Janeiro, Sao Paulo and other cities, improper mining activities, wetland degradation and severe oil spills (C.I.A., par. 7).

Charlotte Perkins Gilmans The Yellow Wallpaper -- short story analysis

  "If a physician of high standing, and one's own husband, assures friends and relatives that there is really nothing the matter with one but temporary nervous depression -- a slight hysterical tendency -- what is one to do?" (Gilman). Many women in the 1800's and 1900's faced hardship when it came to standing up for themselves to their fathers, brothers and then husbands. Charlotte Perkins Gilman, the narrator of the story, is married to physician, who rented a house for the summer to nurse her back to health after her husband think she has neurasthenia but actually suffers from postpartum depression. He suggested the 'rest cure'. She should not be doing any sort of mental of major physical activity, her only job was to relax and not worry about anything. Charlotte was a writer and missed writing.

Dent’s Disastrous Pronouns Essay

Stewart Pidd Hates English contains the following information about pronouns: Pronouns function as replacement words for noun phrases and nouns. Three common types of pronouns that give writers trouble are indefinite pronouns, possessive pronouns, and personal pronouns. Pronouns have different functions. Pronouns that do not refer to an object or a particular person are indefinite pronouns; possessive pronouns show possession; personal pronouns replace an object or a specific person. Writers can use pronouns to prevent unneeded repetition. An antecedent is the noun that comes before or after the pronoun(s) that reference it (Pollitt and Baker 70-85). Faulty pronoun agreement is a common writing error. In â€Å"Go Big or Go Home,† Jimmy Dent fails to make his pronouns agree with their antecedents. Dent makes a pronoun/antecedent agreement error. He writes, â€Å"I was out front working on my old motorcycle and said, ‘Hey, Stewie, when a skater dude goes to Ludville Pipe, they need to go big or go home’†(1). The singular antecedent, â€Å"skater dude† does not agree with the plural pronoun â€Å"they.† To fix the sentence, Dent needs to change the singular antecedent â€Å"skater dude† to a plural antecedent â€Å"skater dudes.† The revised sentence will read, â€Å"I was out front working on my old motorcycle and said, ‘Hey, Stewie, when skater dudes go to Ludville Pipe, they need to go big or go home.’† Dent makes a pronoun/antecedent agreement error with an indefinite pronoun. He states, â€Å"‘Stewart Pidd!’ I yelled, through the rusty spokes or my front rim, ‘Nobody wants to put their relatives in a home’† (2). The singular antecedent â€Å"Nobody† does not agree with the plural possessive pronoun â€Å"their.† To fix the sentence, Dent needs to change the singular indefinite pronoun â€Å"Nobody† to a plural pronoun â€Å"In-laws.† The revised sentence will read, â€Å"‘Stewart Pidd!’ I yelled, through the rusty spokes or my front rim, ‘In-laws don’t want to put their relatives in a home’† Dent makes a pronoun/antecedent agreement error using a collective noun. He writes, â€Å"On a good day, the Dent clan will unite to make their relatives feel like chewed-up gum’† (2). The singular antecedent â€Å"clan† does not agree with the plural possessive pronoun â€Å"their.† The collective noun â€Å"clan† is singular because it a group functioning as a unit. In order to fix the sentence, Dent needs to replace the plural pronoun â€Å"their† with singular possessive pronoun â€Å"our.† The revised sentence will read, â€Å"On a good day, the Dent clan will unite to make our relatives feel like chewed-up gum.† Untrained writers and speakers who make pronoun agreement errors should consider the wise words of Thomas Browne: â€Å"There is music wherever there is harmony, order or proportion.† Good writing is like good music. Having pronoun agreement brings harmony, order, and proportion to one’s writing. Having harmony, order, and proportion creates music in the writing. Works Cited Browne, Thomas. Attackthetext.com.

Business Ethics 5 – Products and Advertising

Advertisements are usually meant to make products to be bought more by customers. Business people try to use the most effective means of advertisement in order to have competitive advantage of other businesspersons in the market. Despite that, advertisements are meant to attract more customers there are too dangerous to be marketed because of the danger that they pause to both the customers and the society in general. For example, people mostly abuse handguns, cigarettes, and some drugs whiuch.In order to market such products there should be strict measures, which should be put in place by the federal government to control the effects of the products, which may cause harm. The American marketing association commits itself to make sure that there is promotion of highest standard of professional ethical norms and values to all its members. Marketers should understand that they do not only work for the organizations but they should also act as the custodian in undertaking activities tha t bring good to the larger population.This means that marketers are supposed to maintain high standards of ethical norms and ethical values. In order to protect the society from harmful effects of marketing of products that are dangerous there are regulations that I would put to marketing of these product. (DesJardins & Hartman, 2008). For cigarettes due to its negative health, effects it has it would be appropriate for markets to put a label on the cigarettes, which warns the smoker that the cigarette is harmful to his or her health and to the health of other members of the society.There should also be no program in the media, which should be sponsored by companies, which manufacture cigarettes. This would reduce creation of positive attitude about cigarettes to the public, which may lead to its increased consumption. The marketers should also not be allowed to put the large posters, which are used for advertisement in public places such as rods. For prescription, drugs there shoul d be a regulation that the drugs should only be sold to those people who have a note from a physician prescribing him or her to take the drugs.They should also a label, which Cleary shows the negative effects they have if abused. For the handguns there should be registering of any handgun that is purchased this would help to reduce criminals obtaining them, licensing of handgun owners, there should also be prohibition of mentally ill people from obtaining handguns. All these regulations would protect the society from many negative effects caused by marketing of handguns. 2. There are usually two criteria that the federal trade commissions use to regulate advertisement. They use deception and fairness as the two criteria.An advertisement is unfair if it has harmful effects to the consumer. For example, if it is an advertisement of a product, which causes negative health effects, then such an advertisement can be termed was unfair. Deceptive advertisement is an advertisement, which us es false or misleading statements to attract customers. Deceptive advertising usually hurts the customers because they may contain statements, which may not be true, which may rue the customer to buy a certain product. This is because the advertisement may contain hidden fees and charges or manipulation of standards of the goods.There is decision-making process, which is used to determine how an advertisement can be unfair. One-step in this process includes looking whether the advertisement hurt and cause injuries the customer. If the advertisement is found to do this then it is taken to be unfair. The injury should be substantial in terms of monetary such as the seller forcing the buyer to goods or services, which are not wanted. The injury, must also be one that the customer could not have reasonably avoided. This is because market place should be self-correcting.The other step involves looking whether the advertisement violates the established public policy, which governs adverti sement. Then there is an examination on whether the advertisement is unethical or unscrupulous. The advertisement should also give the consumer sufficient information so that the customer can be able to make informed decisions (DesJardins & Hartman, 2008).

Calcium Facts - Ca or Atomic Number 20

Calcium Facts - Ca or Atomic Number 20 Calcium is silver to gray solid metal that develops a pale yellow tint. It is element atomic number 20 on the periodic table with the symbol Ca. Unlike most transition metals, calcium and its compounds exhibit a low toxicity. The element is essential for human nutrition. Take a look at calcium periodic table facts and learn about the elements history, uses, properties, and sources. Calcium Basic Facts Symbol: CaAtomic Number: 20Atomic Weight: 40.078Classification: Alkaline EarthCAS Number: 7440-701-2 Calcium Periodic Table Location Group: 2Period: 4Block: s Calcium Electron Configuration Short Form: [Ar]4s2Long Form: 1s22s22p63s23p64s2Shell Structure: 2 8 8 2 Calcium Discovery Discovery Date: 1808Discoverer: Sir Humphrey Davy [England]Name: Calcium derives its name from the Latin calcis which was the word for lime (calcium oxide, CaO) and limestone (calcium carbonate, CaCO3)History: The Romans prepared lime in the first century, but the metal was not discovered until 1808. Swedish chemist Berzelius and Swedish court physician Pontin created an amalgam of calcium and mercury by electrolyzing lime and mercury oxide. Davy managed to isolate pure calcium metal from their amalgam.

Animals skeletons get their rigidity primarily from calcium phosphate. The eggs of birds and shells of mollusks are comprised of calcium carbonate. Calcium is also necessary for plant growth. Calcium is used as a reducing agent when preparing metals from their halogen and oxygen compounds; as a reagent in purification of inert gases; to fix atmospheric nitrogen; as a scavenger and decarbonizer in metallurgy; and for making alloys. Calcium compounds are used in making lime, bricks, cement, glass, paint, paper, sugar, glazes, as well as for many other uses. Miscellaneous Calcium Facts Calcium is the 5th most abundant element in the Earths crust, making up 3.22% of the earth, air, and oceans.Calcium is not found free in nature, but calcium compounds are common. Some of the most common compounds found on Earth are limestone (calcium carbonate - CaCO3), gypsum (calcium sulfate - CaSO4 ·2H2O), fluorite (calcium fluoride - CaF2) and apatite (calcium fluorophosphate - CaFO3P or calcium chlorophosphate - CaClO3P)The top three countries that produce calcium are China, United States and India.Calcium is the main component of teeth and bones. However, too much calcium can lead to kidney stones or artery calcification.Calcium is the fifth most abundant element in the human body. Approximately one third of the mass of the human body is calcium after all water is removed.Calcium burns with a dark red color in a flame test.Calcium is used in fireworks to deepen the color. Calcium salts are used to produce orange in fireworks.Calcium metal is soft enough to cut with a knife, a lthough somewhat harder than the metal lead. People and other animals can often taste the calcium ion. People report is as contributing a mineral, sour, or salty flavor.Calcium metal reacts exothermically with water or acid. Skin contact with calcium metal can cause irritation, corrosion, and chemical burns. Ingesting or inhaling calcium metal can be fatal due to the burns it can produce.

Management Metrics Essay Example | Topics and Well Written Essays - 750 words

Management Metrics - Essay Example Some management systems can also be in place to offer effective and secure network, which is the backbone to any organization (Carter, Ulrich & Goldsmith, 2005). Effective achievement of organizational goals and strategies needs proper network management systems. In a bid to understand efficient and effectiveness in the network management systems, some factors are in consideration in the name of metrics. Metrics directly affects the bottom line of organizational management. There is no single metric which can be solely applicable in assessing the effectiveness of the management group hence the combination of several metrics is applicable. These metrics can undergo common review to gauge the overall effectiveness in the process of organizational goals achievement. Some common metrics in the line of organizational goals tracking includes complexity metrics for operational tasks, business impacts tracking metrics, and scale metrics (Nof, 1994).
