Keydy Vasquez Cerrato Mr. Parker U.S History January 23, 2017 World War 1 DBQ Essay "Our motive will not be revenge or the victorious assertion of the physical might of the nation, but only the vindication of right, of which we are only a single champion." (Wilson) the First World War was one of the most destructive and deadliest wars of all time. Several countries participated in the war. When the se major European nations went to war in 1914, the majority of Americans wanted nothing to do with the raging war. In April 2, 1917, Woodrow Wilson asked Congress for a decla ration of war to make the world "safe for democracy." However, there is sti ll heated and debated argument going on: Could America's involvement in World War One been avoided by Wilson? There are several reasons why President Wilson could not avoid getting America involve in WW1. The Germans attacked boats holding Americans civilians. America was threatened by German and the allies would have lost. For the first few years of WW1, America made sure to stay out of the way. However when the German's attacked and destroyed the Lusitania and other ships, carrying American civilian . Many were in an uproar about the deaths and knew something had to be done to stop the Germans. The German promised that they would not sink unarmed passenger ships without warning, however, twice they promised, and didn't keep it. Americans thought that if these killings were to continue, then the US would have to intervene. In January of 1917, Germany was suffering from supply shortages do to blo ckades taking action. Germany had their foreign Minister Arthur Zimmerman send a telegram to Mexico, stating that if the U.S. declared war on Germany, that Mexico should do the same to the U.S. the tele gram was intercepted and given to American authorities. Although most leaders believed that Mexico would go to war, Americans were shocked with the publication of the telegram and wanted to enter the war. When the war broke out in the summer of 1914, it was like any other war. However when Germany started its campaign of unrestricted submarine warfare, it was clear that Germany and its allies pleaded for help from America. Without America sending in fresh troops and military supplies to the French and The British, The Allies would more than likely have fallen and be under the control of Germany. In conclusion, American involvement in World War 1 couldn't have been avoided by President Wilson. All these event lead to America being involved in the World War. The Lusitania, the Zimmerman Note and the Allies all happened, and no matter how hard America tried to not get involved, it eventually happened and they just got caught in the heat of the moment.

Free Essays on United Nation Free Essays on United Nation Far away, on America’s Pacific Coast, a conference was meeting to create the United Nations. Shortly after Roosevelt’s death, and slightly before the first nuclear bomb test, the world’s leaders argued about the structure of the organization they were building. They debated the â€Å"fundamental human rights† to which they dedicated themselves to. Rights included social progress for better standards of living and equal rights for men and women. Another word was added to this listjustice. The Charter of the United Nations was signed on June 26, 1945. It states that the main objective of the new organization is â€Å"to save succeeding generations from the scourge of war and to reaffirm faith in fundamental human rights.† In 1946, the U.N. established the Commission on Human Rights the principal policy-making body within the U.N. system. On December 10, 1948, the Universal Declaration of Human Rights was adopted and proclaimed by the General Assembly of the United Nations. This act went through by Resolution 217A (III). There were forty-eight votes for the Declaration and none against it. However, there were eight countries that stayed away from this. These countries included White Russia, Czechoslovakia, Poland, Saudi Arabia, Ukraine, USSR, South Africa, and Yugoslavia. The United Nations was designed to include all peace loving states. They also left the great powers to enforce this peace. Although the U.N. failed to attain its dreams, it has provided a valuable â€Å"sounding board† for world opinion. It also developed a center for secret crisis negotiations. Since WWII, the U.N. has helped ease unendurable pressures. The Charter of the United Nations contains noble phrases with regard to human rights and fundamental freedoms. Some skeptics believe that the Declaration of Human Rights is just words. On the contrary, millions of people around the world look to these principles to bring them to the rights and fr...

The Chemistry Behind Sparkler Fireworks

The Chemistry Behind Sparkler Fireworks All fireworks are not created equal! For example, there is a difference between a firecracker and a sparkler. The goal of a firecracker is to create a controlled explosion. A sparkler, on the other hand, burns over a long period of time (up to a minute) and produces a brilliant shower of sparks. Sometimes sparklers are called snowballs in reference to the ball of sparks that surrounds the burning part of the sparkler. Sparkler Chemistry A sparkler consists of several substances: An oxidizerA fuelIron, steel, aluminum, or other metal powderA combustible binder In addition to these components, colorants, and compounds to moderate the chemical reaction also may be added. Often, firework fuel is charcoal and sulfur. Sparklers simply may use the binder as the fuel. The binder is usually sugar, starch, or shellac. Potassium nitrate or potassium chlorate may be used as oxidizers. Metals are used to create the sparks. Sparkler formulae may be quite simple. For example, a sparkler may consist only of potassium perchlorate, titanium or aluminum, and dextrin. Now that youve seen the composition of a sparkler, lets consider how these chemicals react with each other: Oxidizers Oxidizers produce oxygen to burn the mixture. Oxidizers are usually nitrates, chlorates, or perchlorates. Nitrates are made up of a metal ion and a nitrate ion. Nitrates give up 1/3 of their oxygen to yield nitrites and oxygen. The resulting equation for potassium nitrate looks like this: 2 KNO3(solid) → 2 KNO2(solid) O2(gas) Chlorates are made up of a metal ion and the chlorate ion. Chlorates give up all of their oxygen, causing a more spectacular reaction. However, this also means they are explosive. An example of potassium chlorate yielding its oxygen would look like this: 2 KClO3(solid) → 2 KCl(solid) 3 O2(gas) Perchlorates have more oxygen in them but are less likely to explode as a result of an impact than are chlorates. Potassium perchlorate yields its oxygen in this reaction: KClO4(solid) → KCl(solid) 2 O2(gas) Reducing Agents The reducing agents are the fuel used to burn the oxygen produced by the oxidizers. This combustion produces hot gas. Examples of reducing agents are sulfur and charcoal, which react with the oxygen to form sulfur dioxide (SO2) and carbon dioxide (CO2), respectively. Regulators Two reducing agents may be combined to accelerate or slow the reaction. Also, metals affect the speed of the reaction. Finer metal powders react more quickly than coarse powders or flakes. Other substances, such as cornmeal, also may be added to regulate the reaction. Binders Binders hold the mixture together. For a sparkler, common binders are dextrin (a sugar) dampened by water or a shellac compound dampened by alcohol. The binder can serve as a reducing agent and as a reaction moderator. How Does a Sparkler Work? Lets put it all together: A sparkler consists of a chemical mixture that is molded onto a rigid stick or wire. These chemicals often are mixed with water to form a slurry that can be coated on a wire (by dipping) or poured into a tube. Once the mixture dries, you have a sparkler. Aluminum, iron, steel, zinc or magnesium dust or flakes may be used to create the bright, shimmering sparks. The metal flakes heat up until they are incandescent and shine brightly or, at a high enough temperature, actually burn. A variety of chemicals can be added to create colors. The fuel and oxidizer are proportioned, along with the other chemicals, so that the sparkler burns slowly rather than exploding like a firecracker. Once one end of the sparkler is ignited, it burns progressively to the other end. In theory, the end of the stick or wire is suitable to support it while burning. Important Sparkler Reminders Obviously, sparks cascading off of a burning stick present a fire and burn hazard. Less obviously, sparklers contain one or more metals to create the sparks and any colors, so they can present a health hazard. For example, they should not be burned on cakes as candles or otherwise used in a manner which could lead to consumption of the ash. So use sparklers safely and have fun!

Change Management- Its interrelation with Project Management Essay

Change Management- Its interrelation with Project Management - Essay Example Change management is all about managing change and making the change beneficial for everyone. The main field of changes are psychological, business and engineering. Thus with the study of change in organization it is also necessary to have knowledge about change in individual. Kurt Lewin proposed a model in which he described change in three stages. The first stage is of Unfreezing. This stage proposes the change which raze the general thinking of an individual. The second stage is the period of disarray in which how should we replace the current set up also comes into mind. The third stage is refreezing in which all changes are set and comfort level returns back to the original position. This was the last stage which refers that change also provides comfort in work and behavior. The other change model is presented by Kubler Ross. This model describes two stages one is personal and second is emotional. There is formula for change that is that a beneficial change occurs when organizational satisfaction is not good or future immediate change and these changes must have greater effect than the resistance of company to occur change. There are some points that results in successful change: - 1) Awareness :- The people should be aware of change that why it is needed and up to which level. 2) Desire :- It is a person's own desire to have change and to participate in it with enthusiasm and a new vision, 3) Knowledge :- How the change should be done and when, knowledge of these things is of utmost importance. The knowledge of these things helps in a beneficial change. 4) Ability :- Change is not so easy process, to implement change is a very tough job. How to implement new technology and new skills so as to gain maximum output. This ability should be there in a manager. Organizational Change Management :- To manage the change in technology and process and individual behavior on an organizational level is called organizational change management. To manage these terms with an individual behavior gives change in organization. Changes should be handled with great care. The management of these changes should be such that they do not cause any negative impact on the organization. All possible views are considered before making nay change. Types of changes in organization :- 1) Operational change :- These changes effect the ongoing operations of the organizatio

Dry Docks Business Article Example | Topics and Well Written Essays - 1500 words

Dry Docks Business - Article Example Amazingly, manual labor was very much involved during that time where able-bodied men helped in bringing in the ship. An engine known as organois was used in draining the water, allowing the vessel to be supported by cross-beams.(cite) Because of this, dry docks are considered part of inventions belonging to the classical period. Nevertheless, dry docks also were used in China during the Song Dynasty. Obviously, dragon ships during that time which carried imperial couches were made of solid wood. Because of this material, there was a need to repair the wooden hulls since it decayed quickly. It was only in a later period that some wise official suggested the concept of a dry dock. In another part of the world, Henry VIII commissioned the first dry dock was built in Portsmouth in 1495. In modern times, the drydock at Belfast , Ireland was once the biggest drydock in the world. While in the United States, Northrop Grumman Newport News Shipbuildings Dry Dock 12 is considered the largest, situated closely to the slipway where the unlucky Titanic was constructed. Due to the competitive maritime industry, more dry docks have been constructed on many parts of the world. According to the April issue of Maritime, the largest dry dock in the world is now located at Ulsan, South Korea. It was described by the article as : â€Å"†¦.490 meters (1,600 feet) long, 115 meters across and 13.5 meters deep, Hyundai has announced that it now has the world’s largest drydock. Imagine an area roughly the size of 7 soccer fields and that is what you would see at the new H-Dock in Ulsan, South Korea.   The dock is custom designed to build floating production storage and offloading (FPSO) vessels and includes two 1,600ton goliath cranes.   Traditionally FPSO’s hull sides and topside are built separately. The hull is built in a ship

Do the right thing by Spike Lee Essay Example for Free

Do the right thing by Spike Lee Essay I dearly love the film and maintain that its one of the great pictures from the last 10 years. I dont know what the director of this movie (Spike Lee) intended the moral to be, but my take on the film has always been that NO ONE does the right thing, and this is the cautionary element of the movie. The racial message about racial injustice is very deep and one that every race should see. The climax of the movie is very powerful and deep. The heat is blazing, tensions are running high (especially racial ones), and under this kind of pressure no one behaves according to common courtesy and decency. The entire film is a chain of uncontrolled outbursts of anger that lead to everyones misery. The belief that race accounts for differences in human character or ability could be wrong, so is the belief that a particular race is superior to others. Anyone can have a belief like that black, white, whatever. I am not about to buy into this rhetoric that any race shoulders 100% of the blame for racism in America today. Indeed, but racism is a belief, not an action. Sociologists clearly delineate between prejudices and acts of discrimination. One can be racist (prejudice) and not act on it (discriminate). By the same token, one can discriminate against others and not hold racist beliefs (prejudice). There is simply no way, short of telepathy, to determine if anyone is truly racist. One can easily assume that Adolf Hitler was a racist based on his writings and horrific actions, but there is absolutely no way to know for sure that Hitler *truly* hated Jews or simply used the hatred of Jews as a convenient means to attain power. Anyway, those in a position of power have more opportunities to act discriminatorily than those without, but I see no evidence to suggest that The Powers That Be are more *likely* to engage in such behaviors. As such, a discriminatory action by a powerless person can be more effective than the lack of such an action by someone in power. Riots are NEVER true result of racism, but rather the violent, destructive impulses of citizens with no faith in the justice system to take matters into their own hands. They are simply an opportunity for a misguided youth, unsupervised or uninstructed on issued of morality, to appease their violent appetites by destroying the livelihood of someone who is not exactly like  them. In every major example of the last 40 years in US, the violent rioters were not good citizens who felt pushed to the breaking point by some act of injustice, but degenerates whose prejudices against anyone with more money than they found an excuse in the politicized racial arguments to act out what they never truly cared to know was wrong (Heath Petraitis, 1987). The only result of a race riot is hatred, looting, and murder. It is not the answer to anything, and should never be treated as such. It is an insult to the millions of black citizens who seek to live their lives as normal, peaceful, law-abiding citizens of the United States to associate them with the few degenerate thieves and murderers who commit race riots (Singer Singer, 1986). Thats why Do the Right Thing has always touched its viewers. The ending turns a decent, fine comedy-drama into a vessel for class and race related hatred. I do believe in violence as a last measure to protect ones self, or their personal freedoms, or in the case of a moral war. Just look at my signature closing line. I do not in any way believe that the situation in Do the Right Thing presents a need for violence. It is merely a bunch of tempered people retaliating against the brutality of the police by burning an innocent mans pizza shop down, apparently only because he was a white business owner. That is sad. I think, really, this films central theme if there really is one is the path black men in America today face as inspired by their most prominent leaders. Radio Rahiem is easily the wisest in the entire film as hes aware of the dichotomy and thus tries to balance his existence under both directions fight the power constantly playing takes on an entire new meaning here as the film doesnt really know what the power is that PE wants us to fight. Rahiem knows though, its the self. Pretty amazing imagery. But on the other hand, he rarely speaks but instead relies on his radio to speak for him. Likewise, he doesnt understand his own rhetoric on the nature of love and hate. That made him as racist as any other character in the film, with the possible but unlikely exception of smiley, and brings his own death on himself. I wondered what would be the cops reactions if racial positions had been  reversed (ie a black mans pizzeria, a white man accidentally killed after basically making a complete, hostile mess of himself, then resisting arrest etc) Would a white cops strangle a white man to death? Thats where racial issues arise. I was upset at the death of radio Rahiem, but just couldnt escape the fact that he had brought it on himself. No one deserves to die like that. But if he had avoided escalating a completely unnecessary confrontation by assaulting Sal, he wouldnt have died. He was responsible for his own death, just as Sal was responsible for the destruction of the pizzeria (very nearly his own death) when he destroyed Rahiems radio. Radio Raheem was pissed off, his whole existence was that radio. Sure he physically assaulted him, but he didnt say anything like, Ill kill you. Maybe if Radio said in an earlier scene Man Im gonna kill that irk bastard etc. Id be more apt to agree that Radio Rahiem intent was to kill Sal. Technically Sal brought the destruction of the pizzeria on himself too, by (through the chain of events) not putting up pictures of brothers on the walls; but it is his pizzeria and he was within his rights to do so. He yelled racist epithets which is a direct act of aggression and smashed someones property to pieces. Instead of destroying someones property, he should have called the police to escort Buggin out and Radio Rahim. Radio Rahiem was NOT within his rights when he entered the store and refused to turn his radio down. Of course Sal and Radio Rahiem are both racists, everyone in the film is. No one did the right thing in the end, but the unfortunate fact is that, in the final encounter with Radio Rahiem, Sal was just a little more right than Radio Rahiem. Imagine Radio Rahiem and Sal were both black (or white.) Imagine the ultimate reasons behind the clash were not racially based. Radio Rahiem is the aggressor, and because of this, ultimately audience sympathy would lie with Sal. Radio Raheem and Buggin Out were trying to bully an innocent business owner. It was Sals restaurant, if they did not like his regulations than they could leave, but he was entirely within his rights to demand for them to either leave or turn off the music. He certainly gave fair warning, and he never ever tried to physically harm anyone until Radios attack. While it is  unfortunate Radio died, he simply was not worth the destruction that was carried out in his name. I also find it mystifying that Mookie, supposedly the levelheaded character in the movie, was so superficial that he blamed Sal for Radios death. I cannot reconcile myself with the notion that Mookie throwing the trash can through the pizzeria window was even remotely doing the right thing. I sympathize a lot with Sal, but I also sympathize with Mookie. Sal also cared a lot about the black in Bastury, and was genuinely hurt when some of them turned against him. I will vehemently argue that Sals character is not racist; he drops an n-word at the end, but the man is watching his lifes work being torched by arson at the hands of a group of African-Americans; his outburst is understandable and forgivable. Vito, Lees Sister, and the baby are as decent as people could be. Da Mayor is a good man who has made mistakes but is trying to change so at this point hes a good man trying to be a better man. He does drink too many beers with little money, though. One thing that always confused me about this film (although its one of my favorites) is why Mother Sister painfully screams noooo, when only a few minutes beforehand, she was right with the crowd yelling burn it! burn it! it seems like a bit of a flaw to me, but I could be wrong. My guess is the Burn it down Burn it down is with respect to the pizzeria. The noooo is with respect to radio Rahiems death. Lets assume that the film is about the cyclical nature of violence. Does Spike Lee( the director) think that all violence is bad or only certain violence is? After reading Martin Luther Kings quote I thought it was all violence; after reading Malcolm Xs quote I got the message that some violence is ok. I know that Blacks have been prejudiced against for a long time, but I dont see how violence ever solved their problem. It seems to me that Martin Luther Kings non-violence approach ultimately did much more to further equality than Malcolm Xs approach of violence-sometimes-needed approac h. The cops didnt necessarily care for Sal or anyone there. They didnt kill Rahiem because they wanted revenge. They did a right think by choking Rahiem, but they should have weakened him enough to handcuff him and then have thrown him in the police car. I doubt either Clubbing or strangling  will ever equate to, to use your words, holding him in place until he calmed down. I doubt those are the only options law enforcement officers have. They shouldnt have killed him. It was an extreme use of force pure and simple. The key being that if as you say they were trying to prevent Sal from being chocked by a criminal than why didnt they release their choke hold on Radio Rahiem after he had let go of Sal? They kept choking him long after he was a threat to anyone and it was obvious he himself was being choked to death. Why did they not throw him to the ground at that time and handcuff him? They didnt even try. In the film, Da Mayor says you gotta Do The Right Thing. Rahiem does not because he wont respect Sals wishes to turn off or turn down the radio (Also didnt respect Sals decision to represent only his culture in the pizzeria). Bugging Out is just a racist who knows nothing and wants to pretend to have a calling so he rides in on Radios coattails. Rahiem did the wrong thing and Sal did nothing wrong until he uttered the N-word. I dont think Sal meant it in that way. He was angry so he exploited a characteristic of Radios boom box. The people were angry at Sal for saying the n-word but they didnt go against Sal. They got confused and yelled. Then the police came in and everything went up in flames. Obviously, a spark leads to a fire. The spark: The police killing Rahiem. The Fire: The mob. It was understandable for there to be a riot and it was understandable that they got angry at white men in general because they are black people and they live in an ugly area. But just because its understandable, doesnt mean its right. The name of the movie is Do The Right Thing. And to be honest, even though thats very straight and very literal, towards the end it becomes ironic. The moment that they could do the right thing, they did the worst thing of them all. And that riot could have been right but it went wrong. Their anger went in the wrong direction. Things just happen. Sals pizzeria going down in flames is symbolic of the fact that people just destroy each other. And in the end, the face of the oppressor (The white man) is thrown on every white body and someone with the face of the oppressor is oppressed. Well, theres a line (Not from this movie) that goes You become the monster so the monster will not break you. You become what you terrify you. And in  this case, the oppressed (The black community) gets so fed up (Throughout the entire movie, there is talk of there recently being a police brutality situation involving black civilians being killed) with being oppressed that they become what they hate and they oppress someone else: Someone whos been more of a family member to them then most of their families has a different face than they do. He has the face of the monster, and they dont like past skin deep and treat him the way they should treat the people who do oppress them. And its painful and we dont know what to think. Im the least racist person in the world and Im also the person who is more annoyed than anyone with jokes being allowed to be made about white people and not about black people. I dont like going to the park and having some guy say, White boy, dont want none of this. It irritates me because I want plenty. Sometimes it gets so hard to hear all the unfairness and listen to a persons lack of understanding for another. This film is just a day. Its the hottest day of the summer. You can do nothing, you can do something, or you can Do The Right Thing. You can. So do it.

The Red Shoes :: English Literature Essays

The Red Shoes ‘The Red Shoes’ is an imaginary and unreal story related by Hans Christian Anderson. Anderson makes effective use of fantasy to teach a moral lesson. He builds up the story in such a way that the reader does not care for the validity of the incidents. The moral lesson is that the proud and the disobedient must suffer. Disobedience is a sin, and according to the Christian belief it is what started the demise in the heavens above, so anybody who commits it must suffer. Whatever sins man commits in his lifetime he is punished for them. If only he repents for his sins can he be forgiven and at least he can die in peace. God forgives them only when they repent for their sins. The story also presents another facts of the Christian belief about sin and punishment, which is based on the strict principles of repentance and forgiveness. In the story Karen is a poor but beautiful girl. At the death of her mother, a rich old lady takes her to her home and brings her up. The widow of the cobbler gave Karen a pair of red shoes, which she wore for the first time on her mother’s funeral. The old lady who adopted Karen disliked, the red shoes greatly because of Karen’s obsession for them and so she burnt them. Then once Karen saw the princess wearing beautiful red shoes. Her love for these shoes got re-ignited; she liked them a lot indeed. Karen grew up to be a beautiful damsel. She was to be made the member of the church. Her foster mother, the rich old lady bought her a lovely pair of shoes incidentally those shoes were also red in color. This fact has escaped the old lady’s notice, but Karen found them to be exactly what she yearned for. She went to church in those red shoes. She thought that everyone in the church was looking at her shoes. She wore them at the time of confirmation, which was not the proper occasion to wear them. Karen felt very proud of them. She even forgot to pray in the church when the old lady came to know about it she told Karen not to wear those shoes in future but once again she went to the church wearing those shoes. This accounted for the sin of disobedience she committed.

Forward the Foundation Chapter 20

22 Yugo Amaryl said, â€Å"Here you are again, Dors.† â€Å"Sorry, Yugo. I'm bothering you twice this week. Actually you don't see anyone very often, do you?† Amaryl said, â€Å"I don't encourage people to visit me, no. They tend to interrupt me and break my line of thought. Not you, Dors. You're altogether special, you and Hari. There's never a day I don't remember what you two have done for me.† Dors waved her hand. â€Å"Forget it, Yugo. You've worked hard for Hari and any trifling kindness we did for you has long been overpaid. How is the Project going? Hari never talks about it-not to me, anyway.† Amaryl's face lightened and his whole body seemed to take on an infusion of life. â€Å"Very well. Very well. It's difficult to talk about it without mathematics, but the progress we've made in the last two years is amazing-more than in all the time before that. It's as though, after we've been hammering away and hammering away, things have finally begun to break loose.† â€Å"I've been hearing that the new equations worked out by Dr. Elar have helped the situation.† â€Å"The achaotic equations? Yes. Enormously.† â€Å"And the Electro-Clarifier has been helpful, too. I spoke to the woman who designed it.† â€Å"Cinda Monay?† â€Å"Yes. That's the one.† â€Å"A very clever woman. We're fortunate to have her.† â€Å"Tell me, Yugo-You work at the Prime Radiant virtually all the time, don't you?† â€Å"I'm more or less constantly studying it. Yes.† â€Å"And you study it with the Electro-Clarifier.† â€Å"Certainly.† â€Å"Don't you ever think of taking a vacation, Yugo?† Amaryl looked at her owlishly, blinking slowly. â€Å"A vacation?† â€Å"Yes. Surely you've heard the word. You know what a vacation is.† â€Å"Why should I take a vacation?† â€Å"Because you seem dreadfully tired to me.† â€Å"A little, now and then. But I don't want to leave the work.† â€Å"Do you feel more tired now than you used to?† â€Å"A little. I'm getting older, Dors.† â€Å"You're only forty-nine.† â€Å"That's still older than I've ever been before.† â€Å"Well, let it go. Tell me, Yugo-just to change the subject. How is Hari doing at his work? You've been with him so long that no one could possibly know him better than you do. Not even I. At least, as far as his work is concerned.† â€Å"He's doing very well, Dors. I see no change in him. He still has the quickest and brightest brain in the place. Age is having no effect on him-at least, not so far.† â€Å"That's good to hear. I'm afraid that his own opinion of himself is not as high as yours is. He's not taking his age well. We had a difficult time getting him to celebrate his recent birthday. Were you at the festivities, by the way? I didn't see you.† â€Å"I attended part of the time. But, you know, parties of that kind are not the sort of thing I feel at home with.† â€Å"Do you think Hari is wearing out? I'm not referring to his mental brilliance. I'm referring to his physical capacities. In your opinion, is he growing tired-too tired to bear up under his responsibilities?† Amaryl looked astonished. â€Å"I never gave it any thought. I can't imagine him growing tired.† â€Å"He may be, just the same. I think he has the impulse, now and then, to give up his post and hand the task over to some younger man.† Amaryl sat back in his chair and put down the graphic stylus he had been fiddling with ever since Dors had entered. â€Å"What! That's ridiculous! Impossible!† â€Å"Are you sure?† â€Å"Absolutely. He certainly wouldn't consider such a thing without discussing it with me. And he hasn't.† â€Å"Be reasonable, Yugo. Hari is exhausted. He tries not to show it, but he is. What if he does decide to retire? What would become of the Project? What would become of psychohistory?† Amaryl's eyes narrowed. â€Å"Are you joking, Dors?† â€Å"No. I'm just trying to look into the future.† â€Å"Surely, if Hari retires, I succeed to the post. He and I ran the Project for years before anyone else joined us. He and I. No one else. Except for him, no one knows the Project as I do. I'm amazed you don't take my succession for granted, Dors.† Dors said, â€Å"There's no question in my mind or in anyone else's that you are the logical successor, but do you want to be? You may know everything about psychohistory, but do you want to throw yourself into the politics and complexities of a large Project and abandon much of your work in order to do so? Actually it's trying to keep everything moving smoothly that's been wearing Hari down. Can you take on that part of the job?† â€Å"Yes, I can and it's not something I intend to discuss. Look here, Dors. Did you come here to break the news that Hari intends to ease me out?† Dors said, â€Å"Certainly not! How could you think that of Hari! Have you ever known him to turn on a friend?† â€Å"Very well, then. Let's drop the subject. Really, Dors, if you don't mind, there are things I must do.† Abruptly he turned away from her and bent over his work once more. â€Å"Of course. I didn't mean to take up this much of your time.† Dors left, frowning. 23 Raych said, â€Å"Come in, Mom. The coast is clear. I've sent Manella and Wanda off somewhere.† Dors entered, looked right and left out of sheer habit, and sat down in the nearest chair. â€Å"Thanks,† said Dors. For a while she simply sat there, looking as if the weight of the Empire were on her shoulders. Raych waited, then said, â€Å"I never got a chance to ask you about your wild trip into the Palace grounds. It isn't every guy who has a mom who can do that.† â€Å"We're not talking about that, Raych.† â€Å"Well then, tell me. **You're not one for giving anything away by facial expressions, but you look sorta down. Why is that?† â€Å"Because I feel, as you say, sorta down. In fact, I'm in a bad mood because I have terribly important things on my mind and there's no use talking to your father about it. He's the most wonderful man in the world, but he's very hard to handle. There's no chance that he'd take an interest in the dramatic. He dismisses it all as my irrational fears for his life-and my subsequent attempts to protect him.† â€Å"Come on, Mom, you do seem to have irrational fears where Dad's concerned. If you've got something dramatic in mind, it's probably all wrong.† â€Å"Thank you. You sound just like he does and you leave me frustrated. Absolutely frustrated.† â€Å"Well then, unburden yourself, Mom. Tell me what's on your mind. From the beginning.† â€Å"It starts with Wanda's dream.† â€Å"Wanda's dream! Mom! Maybe you'd better stop right now. I know that Dad won't want to listen if you start that way. I mean, come on. A little kid has a dream and you make a big deal of it. That's ridiculous.† â€Å"I don't think it was a dream, Raych. I think what she thought was a dream were two real people, talking about what she thought concerned the death of her grandfather.† â€Å"That's a wild guess on your part. What possible chance does this have of being true?† â€Å"Just suppose it is true. The one phrase that remained with her was ‘lemonade death.' Why should she dream that? It's much more likely that she heard that and distorted the words she heard-in which case, what were the undistorted words?† â€Å"I can't tell you,† said Raych, his voice incredulous. Dors did not fail to catch that. â€Å"You think this is just my sick invention. Still, if I happen to be right, I might be at the start of unraveling a conspiracy against Hari right here in the Project.† â€Å"Are there conspiracies in the Project? That sounds as impossible to me as finding significance in a dream.† â€Å"Every large project is riddled with angers, frictions, jealousies of all sorts.† â€Å"Sure. Sure. We're talking nasty words and faces and nose thumbing and tale bearing. That's nothing at all like talking conspiracy. It's not like talking about killing Dad.† â€Å"It's just a difference in degree. A small difference-maybe.† â€Å"You'll never make Dad believe that. For that matter, you'll never make me believe that.† Raych walked hastily across the room and back again, â€Å"And you've been trying to nose out this so-called conspiracy, have you?† Dors nodded. â€Å"And you've failed.† Dors nodded. â€Å"Doesn't it occur to you that you've failed because there is no conspiracy, Mom?† Dors shook her head. â€Å"I've failed so far, but that doesn't shake my belief that one exists. I have that feeling.† Raych laughed. â€Å"You sound very ordinary, Mom. I would expect more from you than ‘I have that feeling.†Ã¢â‚¬Ëœ â€Å"There is one phrase that I think can be distorted into ‘lemonade.' That's ‘layman-aided.' â€Å" â€Å"Laymanayded? What's that?† â€Å"Layman-aided. Two words. A layman is what the mathematicians at the Project call nonmathematicians.† â€Å"Well?† â€Å"Suppose,† interjected Dors firmly, â€Å"someone spoke of ‘layman-aided death,' meaning that some way could be found to kill Hari in which one or more nonmathematicians would play an essential role. Might that not have sounded to Wanda like ‘lemonade death,' considering that she had never heard the phrase ‘layman-aided' any more than you did, but that she was extraordinarily fond of lemonade?† â€Å"Are you trying to tell me that there were people in Dad's private office, of all places. How many people, by the way?† â€Å"Wanda, in describing her dream, says two. My own feeling is that one of the two was none other than Colonel Hender Linn of the junta and that he was being shown the Prime Radiant and that there must have been a discussion involving the elimination of Hari.† â€Å"You're getting wilder and wilder, Mom. Colonel Linn and another man in Dad's office talking murder and not knowing that there was a little girl hidden in a chair, overhearing them? Is that it?† â€Å"More or less.† â€Å"In that case, if there is mention of laymen, then one of the people, presumably the one that isn't Linn, must be a mathematician.† â€Å"It would seem to be so.† â€Å"That seems utterly impossible. But even if it were true, which mathematician do you suppose might be in question? There are at least fifty in the Project.† â€Å"I haven't questioned them all. I've questioned a few and some laymen, too, for that matter, but I have uncovered no leads. Of course, I can't be too open in my questions.† â€Å"In short, no one you have interviewed has given you any lead on any dangerous conspiracy.† â€Å"No.† â€Å"I'm not surprised. They haven't done so, because-â€Å" â€Å"I know your ‘because,' Raych. Do you suppose people are going to break down and give away conspiracies under mild questioning? I am in no position to try to beat the information out of anyone. Can you imagine what your father would say if I upset one of his precious mathematicians?† Then, with a sudden change in the intonation of her voice, she said, â€Å"Raych, have you talked to Yugo Amaryl lately?† â€Å"No, not recently. He's not one of your sociable creatures, you know. If you pulled the psychohistory out of him, he'd collapse into a little pile of dry skin.† Dors made a face at the picture and said, â€Å"I've talked to him twice recently and he seems to me to be a little withdrawn. I don't mean just tired. It is almost as though he's not aware of the world.† â€Å"Yes. That's Yugo.† â€Å"Is he getting worse lately?† Raych thought awhile. â€Å"He might be. He's getting older, you know. We all are. Except you, Mom.† â€Å"Would you say that Yugo had crossed the line and become a little unstable, Raych?† â€Å"Who? Yugo? He has nothing to be unstable about. Or with. Just leave him at his psychohistory and he'll mumble quietly to himself for the rest of his life.† â€Å"I don't think so. There is something that interests him-and very strongly, too. That's the succession.† â€Å"What succession?† â€Å"I mentioned that someday your father might want to retire and it turns out that Yugo is determined-absolutely determined-to be his successor.† â€Å"I'm not surprised. I imagine that everyone agrees that Yugo is the natural successor. I'm sure Dad thinks so, too.† â€Å"But he seemed to me to be not quite normal about it. He thought I was coming to him to break the news that Hari had shoved him aside in favor of someone else. Can you imagine anyone thinking that of Hari?† â€Å"It is surprising-† Raych interrupted himself and favored his mother with a long look. He said, â€Å"Mom, are you getting ready to tell me that it might be Yugo who's at the heart of this conspiracy you're speaking of? That he wants to get rid of Dad and take over?† â€Å"Is that entirely impossible?† â€Å"Yes, it is, Mom. Entirely. If there's anything wrong with Yugo, it's overwork and nothing else. Staring at all those equations or whatever they are, all day and half the night, would drive anyone crazy.† Dors rose to her feet with a jerk. â€Å"You're right.† Raych, startled, said, â€Å"What's the matter?† â€Å"What you've said. It's given me an entirely new idea. A crucial one, I think.† Turning, without another word, she left. 24 Dors Venabili disapproved, as she said to Hari Seldon â€Å"You've spent four days at the Galactic Library. Completely out of touch and again you managed to go without me.† Husband and wife stared at each other's image on their holoscreens. Hari had just returned from a research trip to the Galactic Library in Imperial Sector. He was calling Dors from his Project office to let her know he'd returned to Streeling. Even in anger, thought Hari, Dors is beautiful. He wished he could reach out and touch her cheek. â€Å"Dors,† he began, a placating note in his voice, â€Å"I did not go alone. I had a number of people with me and the Galactic Library, of all places, is safe for scholars, even in these turbulent times. I am going to have to be at the Library more and more often, I think, as time goes on.† â€Å"And you're going to continue to do it without telling me?† â€Å"Dors, I can't live according to these death-filled views of yours. Nor do I want you running after me and upsetting the librarians. They're not the junta. I need them and I don't want to make them angry. But I do think that I-we-should take an apartment nearby.† Dors looked grim, shook her head, and changed the subject. â€Å"Do you know that I had two talks with Yugo recently?† â€Å"Good. I'm glad you did. He needs contact with the outside world.† â€Å"Yes, he does, because something's wrong with him. He's not the Hugo we've had with us all these years. He's become vague, distant, and-oddly enough-passionate on only one point, as nearly as I can tell-his determination to succeed you on your retirement.† â€Å"That would be natural-if he survives me.† â€Å"Don't you expect him to survive you?† â€Å"Well, he's eleven years younger than I am, but the vicissitudes of circumstance-â€Å" â€Å"What you really mean is that you recognize that Yugo is in a bad way. He looks and acts older than you do, for all his younger age, and that seems to be a rather recent development. Is he ill?† â€Å"Physically? I don't think so. He has his periodic examinations. I'll admit, though, that he seems drained. I've tried to persuade him to take a vacation for a few months-a whole year's sabbatical, if he wishes. I've suggested that he leave Trantor altogether, just so that he is as far away from the Project as possible for a while. There would be no problem in financing his stay on Getorin-which is a pleasant resort world not too many light-years away.† Dors shook her head impatiently. â€Å"And, of course, he won't. I suggested a vacation to him and he acted as though he didn't know the meaning of the word. He absolutely refused.† â€Å"So what can we do?† said Seldon. Dors said, â€Å"We can think a little. Yugo worked for a quarter of a century on the Project and seemed to maintain his strength without any trouble at all and now suddenly he has weakened. It can't be age. He's not yet fifty.† â€Å"Are you suggesting something?† â€Å"Yes. How long have you and Yugo been using this Electro-Clarifier thing on your Prime Radiants?† â€Å"About two years-maybe a little more.† â€Å"I presume that the Electro-Clarifier is used by anyone who uses the Prime Radiant.† â€Å"That's right.† â€Å"Which means Yugo and you, mostly?† â€Å"Yes.† â€Å"And Yugo more than you?† â€Å"Yes. Yugo concentrates fiercely on the Prime Radiant and its equations. I, unfortunately, have to spend much of my time on administrative duties.† â€Å"And what effect does the Electro-Clarifier have on the human body?† Seldon looked surprised. â€Å"Nothing of any significance that I am aware of.† â€Å"In that case, explain something to me, Hari. The Electro-Clarifier has been in operation for over two years and in that time you've grown measurably more tired, crotchety, and a little out of touch. Why is that?†** â€Å"I'm getting older, Dors.† â€Å"Nonsense. Whoever told you that sixty is crystallized senility? You're using your age as a crutch and a defense and I want you to stop it. Yugo, though he's younger, has been exposed to the Electro-Clarifier more than you have and, as a result, he is more tired, more crotchety, and, in my opinion, a great deal less in touch than you are. And he is rather childishly intense about the succession. Don't you see anything significant in this?† â€Å"Age and overwork. That's significant.† â€Å"No, it's the Electro-Clarifier. It's having a long-term effect on the two of you.† After a pause, Seldon said, â€Å"I can't disprove that, Dors, but I don't see how it's possible. The Electro-Clarifier is a device that produces an unusual electronic field, but it is still only a field of the type to which human beings are constantly exposed. It can't do any unusual harm. In any case, we can't give up its use. There's no way of continuing the progress of the Project without it.† â€Å"Now, Hari, I must ask something of you and you must cooperate with me on this. Go nowhere outside the Project without telling me and do nothing out of the ordinary without telling me. Do you understand?† â€Å"Dors, how can I agree to this? You're trying to put me into a straitjacket.† â€Å"It's just for a while. A few days. A week.† â€Å"What's going to happen in a few days or a week?† Dors said, â€Å"Trust me. I will clear up everything.†

African Rock Python Essay

The African rock python. It is Domain: Eukarya. Domain is the highest taxonomic rank of organisms, higher than a kingdom. The African rock python falls under Eukarya because it is a multicellular organism composed of eukaryotic cells. It is Kingdom: Anamalia. Kingdom is the second highest rank. It falls under Anamalia for obvious reasons. It is Phylum: Chordata. Phylum is the primary division of the plant or animal kingdom. It is Class: Reptilia. Class is a group of related plants or animals, in the general classification of plants and animals. The African rock python falls under Reptilia because it has a characteristic of being cold-blooded. It is Order: Squamata. Order is a taxonomic rank used in classifying organisms, generally below the class, and comprised of families sharing a set of similar nature or characteristics. The African rock python shed their skin periodically and have very flexible jaws, which are characteristics of Squamata. It is Family: Pythonidae. Organisms belonging to the same family would have evolved from the same ancestors and share relatively common characteristics. The Pythonidae family is a family of non-venomous snakes who are powerful constrictors that wrap around their prey to kill it. This family includes the African rock python. It’s Genus: Python. In binomial nomenclature, the genus is used as the first word of a scientific name. It’s Species: Python sebae. Species is the second part of the name is the binomial nomenclature. The name Python Sebae was derived from the Greek mythology, which refers to a huge serpent. The largest snake in Africa and the third largest snake in the world, the African rock python, have long bulky bodies. Snakes are considered vertebrates because they have a backbone, a closed circulatory system, where the heart and blood vessels are continuously contracting. The blood never leaves the blood vessels. The outer layer of the epidermis is thick and lacks glands. It is characterized by keratin scales. Ranging anywhere from an average size of 18 to 20 feet long, but can grow up to 28 feet long! The females are larger than the males and can weigh almost 300lbs. However the size may vary according to their natural habitat. It is amazing to note that in areas where there is a higher population, the size of the African rock python has been smaller in size, as compared to areas where human habitat is less; the African Rock Python snake is much bigger in ize. African Rock Pythons are often tan with brown spots that have black outlines. This helps them camouflage in the environment, and gives them an advantage to hunt their prey or hide from potential predators. This is considered cryptic camouflage. A V-shape noticeably marks the face. This python is non-venomous, and has teeth curved inward to help pull in prey when eating. Like all pythons, the scales of the African rock python are small and smooth, and those nearby the lips control heat-sensitive pits, which are used to distinguish warm-blooded prey, even in the dark. Pythons also possess two functioning lungs, unlike more â€Å"advanced† snakes which have only one, and also have small, visible pelvic spurs, believed to be the remnants of hind limbs. It is said that snakes are evolved from lizards that burrowed in tunnels or in water, and the use of hind legs made it harder for them to burrow. Over time there legs started to grow shorter and eventually becoming useless, leaving behind what is now known as there spurs, located right before the anus. The rate of this evolution occurred at a slow constant pace over millions of years. This evidence of evolution would be considered phylogeny, the evolutionary relationship among species. African rock pythons reside in sub-Saharan Africa, but prefer evergreen forests or moist, open savannahs. You will always most likely find an African rock python associated with water and often are found near rivers and lakes. The African rock python has recently been found on the loose in Florida. Not many know how the massive snake happened to come about in Florida. Many believe they were released purposely, because the owner or breeder was ill-equipped for the intensity of this particular snake. A frightening factor has arisen since the African rock python has inhabited the south Florida territory. The Burmese python has already established foothold in the Everglades. The fear of a new â€Å"Super Snake† breed arising if the Burmese and African rock python were to mate, strikes fear that a hybrid python may be on the rise in the Everglades. Knowing that the African rock is bigger and more aggressive than the Burmese python which is about 17 feet long, the â€Å"super snake† would surpass that length. It would not only hamper the ecosystem but would also be dangerous for families with small children. The python hunts by smelling food with its tongue, flicking it up and down. Although the African rock python are already powerful on land, this brainy serpent employs an even more impressive tactic underwater. Ever adaptable, the pythons that reside near water thrive on fish. Much older snakes can use the water to its advantage and hunt greater prey. They can remain under water and every 30 minutes come up to take a discrete breath. It uses heat-sensing organs, called photoreceptors to detect warm-blooded prey. Because the African rock python is non-venomous it squeezes its food. Every time the prey exhales, the python constricts a little more, so that inhalation becomes increasingly difficult. Death is caused mostly by cardiac arrest rather than myths or urban legends articulating that their prey was crushed to death. African rock pythons, as well as every python, are carnivores. Their diet consists of large rodents, monkeys, antelopes, crocodiles, dogs, goats, and poultry . They have strong acids inside their stomach which helps them to digest their food. It is rare of the African rock python hunting for humans. After eating a large animal, the python needs no food for a long time, and may rest for weeks. In this engorged state, it is most vulnerable to attack by predators. In most cases if the snake feels threatened it will regurgitate the food and escape to shelter. African Rock Python becomes sexually active as early as 3-5 years old and reproduce during the spring. The female snake lets out a pheromone which attracts the male snake to mate. During the breeding season both the sexes fast and the female continues the fast till the eggs are hatched. African rock pythons fall under the subclass: protheria. They are oviparous, meaning they reproduce by laying eggs, which hatch outside the mother’s body. Surprisingly the python shows distinct mother instincts by coiling around the eggs, protecting them from predators, and incubating the eggs to help with development until they hatch, which is about 90 days. Which makes this species rather interesting as parenting is quite a foreign concept to reptiles. Hatchlings are between 18–24 inches in length, and have temper when born. Some are known to strike when hatching. They are nearly identical to adults, except with more distinguishing colors. African Rock Python can live up to 12 years in wild however they can live up to 30 years in captivity. It is said that the African rock python is does not run the risk of extinction, but is listed on Appendix II of the Convention on International Trade in Endangered Species (CITES). There is a high demand for the python’s skin and meat in the market, mostly to make leather, belts and purses. Exporting of these exotic animals is known to be illegal. Some of the African rock python’s habitats are also known to be under threat due to destruction for the oil industry. In some cases the African rock python might be a prey to hyenas or the African wild dogs during their digestion period, but aside from humans, adult African rock pythons have very few natural predators due to their large size. For the reason that these species can reach significant sizes, their constricting power must be respected. Most cases found of African rock pythons swallowing a crocodile whole, later to be found that the crocodile was not digested and penetrated the skin of the python. Although this species can easily kill an adult, there are only a few cases in which the victim, in most cases a child, was actually consumed. Rare cases have been reported of an African rock python consuming a 10 year old boy, or attempting to eat a child. In another case a 13 year old was swallowed, but the python was forced to regurgitate the body. The African rock python began being known as â€Å"Man-eating snake†. This factor of their strength, as well as size, separates this python from most other snakes. Maybe even all reptiles for that matter. African rock pythons have been known to go after monitor lizards, which are known to very aggressive and strong. This is one reason why African rock pythons should not be considered a first pet for someone who wants to own a snake. People who are ill-equipped owners or breeders do not know what to expect and end up getting ahead of themselves, and can no longer handle a beast that they just irresponsibly release them, no knowing what their actions have lead to. The African rock python has many fascinating features, from the way they hunt, the way they eat, live, breed, how big of an importance they to the environment not only around animals but humans as well. It’s amazing at how big they can get and to know exactly how powerful they can be. The types of animals they can bring down are twice their size. Their lifestyle captures my attention. Besides the fact, that I am attracted to exotic pets, I own a Royal python, commonly known as a Ball python. Similar to the African rock python, the ball python is considered more docile and smaller in length and hopefully size in the future, but it is still a dangerous animal and should not be handled lightly. This research paper has added to my knowledge of the African rock python as well as other common snakes. I have learned that what may seem to be a harmless hatchling at birth, can grow into an overgrown, powerful killing machine. This is also known as fatal attraction. I know that if I wanted to know release my ball python into the wild I would know how to do it properly. The choice of owning a python, or any snake for that matter , is a choice that needs to be taken seriously, these animals require attention, a stable and healthy living environment, and patience. You never know what to expect from them or when to expect something from them.

Civil Rights Essays - Counterculture Of The 1960s, Free Essays

Civil Rights Essays - Counterculture Of The 1960s, Free Essays Civil Rights The Reverend Dr. Martin Luther King Jr., in his book Why We Cant Wait, quite correctly named the civil rights struggles of the mid-twentieth century the Third American Revolution. Though it is most often attributed to the 1960s the civil rights movement found its start in the decade before that, the peaceful 50s. The civil rights movement actually started with legal battles before moving into the streets of American cities. The Supreme Court ordered the desegregation of schools with all deliberate speed and overturned its former separate but equal policy that had for so long been the law of the land. This led to the tokenism that MLK decried in his book, and it also led to the realization that there wouldnt be equal rights gained through the courts alone, they had to take their struggle to the streets. The NAACP and other organizations continued their struggle with the judicial system, but new organizations formed to help the people in a different way. It was in this time when the SLCC and SNCC were formed to fight, rather to not fight, for equality. Non-violence was the core of the mainstream movement and it was their main weapon. From the bus boycotts of Montgomery to the lunch counter sit-ins across the nation not a black fist was raised in anger. They were beaten, spat upon and cursed and still did not fight back. This was a brilliant public relations strategy in action, for every time the protestors were shown on the news, it was them acting peacefully and a white mob attacking them. These images alone helped to win over many supporters and force the national government to step in to help the cause of civil rights. One of the main goals of the passive resistors was to gain public support and force the government to uphold the Supreme Courts controversial rulings, such as what happened with Central High School when President Kennedy nationalized the Arkansas National Guard and the Interstate Commerce Comm. forced the desegregat ion of the interstate bus lines. Without lifting a finger they changed the way the nation was run. As the years went on African Americans became even more willing to stand up for their rights, to the point where MLK led a march on Washington D.C. Slowly but surely the small pocket of dissidents turned into a nationwide movement that reshaped the way the constitution was interpreted and tried to help make sure that all men really were created equal. Even the killings of important persons like MLK, Medgar Evars, and Malcolm X couldnt stop the flow once it had been released. The men became martyrs to the cause and more powerful than they ever were when they were alive. Ultimately the goals of the civil rights movement were quite simple. They wanted to end discrimination, to become accepted as American citizens with all the rights, duties and privileges that entails. They wanted the power to become whatever they wanted in life, to not be held back by mere melatonin but instead be accepted everywhere by everyone as a fellow human being, regardless of race.

Analyse The Concept Of Opportunity Cost Economics Essay

Analyse The Concept Of Opportunity Cost Economics Essay Introduction The answers start with the basic theories of microeconomics and contact with an analysis of actual cases to solve the following four problems. It refers from the opportunity cost, scarcity of resources, cross-price elasticity, income effect, substitution effect, the producer surplus to long-run equilibrium for a perfectly competitive industry. 1. (a) The concept of opportunity cost is due to the scarcity of resource, the scarcity of resource determines that the resource can not be used for purpose B any longer if the resource has been used for purpose A. Therefore, opportunity cost means that if a resource can be not only used for one purpose but also used for another purpose (if it used for one purpose, it must give up other uses due to the scarcity of resources), then the opportunity cost indicates that the resource used for purpose A refers to the net incomes it should have got if it was used for a better purpose B. That is, if the resource has been used for a purpos e A, you will lose the possible incomes, so it is a loss of opportunity. This loss must be taken into account when the company choose the use of corporate resources in the selection, only the opportunity cost is the real cost to the economists. Opportunity cost is characterized by selective and hidden. The friend above says he has a free pass to go to the game of cricket between Australia and South Africa and it won’t cost me anything, according to the concept of opportunity cost above, he is wrong about the cost of going to watch the cricket match .The reasons are as follows. On the one hand, I will lose my time on watching the match; on the other hand, if I do not go with him, I can do my own business, such as study or something meaningful, so I would have lost the incomes I should have got. (b) Resources are scarce. Scarcity of resources has two meanings: One meaning is that we have to cost if we want to obtain any resources . The other one is that any resources are limite d relative to people’s needs and desires. Nowadays, universities are confronted with the problem of scarcity of resources with respect to the degree courses it provides. It is the higher quality teaching resources and the scarcity of supply of higher education demand for high quality teaching resources that restrict the improvement of the quality of higher education. There are both structural imbalances and the total lack of teaching resources problems. The main factors that affect our level of sharing of teaching resources and efficiency are resource development, resource sharing mechanism design and resource sharing of technical support. For example, Ideological and Political Theory Course teaching resource are scarcity, which can not meet the normal practice of teaching needs; the scattered, idle and waste related issues in the use of the Ideological and Political Theory Course teaching resource are also important factors that affect the supply and demand balance in additi on to its own supply shortage. In specifically speaking, there are two aspects. On the one hand is the disperse regions, which refers to the non-uniformity of time and space in the rule of teaching resources in the Ideological and political theory; on the other hand is the non-uniformity on time, which refers to the differences between the history resources and reality performance.

When Marian Sang Essay Example | Topics and Well Written Essays - 500 words

When Marian Sang - Essay Example Anderson was born and brought up in a humble family, but her magnificence in singing made her talent recognised as she would sing in many city choirs. However, as the book illustrates, Marian was not lucky as troubles haunted her early in life. Her father died when she was only twelve years of age, and despite her singing talent, the Philadelphia Music Academy denied her a chance to prove her prowess in singing due to her race. All the same, her mother encouraged her to soldier on, and it was no until she saw a performance by the Metropolitan Opera of Madame Butterfly that her dream of singing shone again. Despite being from a humble background, Marian made many tours in Europe and America where she was presented with great opportunities. The book is a non-fiction story told in utmost simplicity and depth of emotions to children between 3 and 8 years. The book offers many themes of learning to children on the need to be patient, courageous, have the perseverance to succeed in their talents especially at an early beginning. The inspiring part of a poor girl with a talent is a motivation to children not to give up in chasing their dreams despite their weak nature. Through perseverance, children are called to hold on to what they believe. The book comes with illustrations that depict the young girl singing, which brings out the simplicity of the girl and appeals to the emotions of not only children but also the narrators of such a story. The illustrations also break the monotony of the text to present children with some space to reflect about the life of the young girl. Through the images of the young girl, children can connect the story to their lives, which makes the book a real motivation to children in pursuit of th eir talents early in life. Throughout the book, the author utilised words that conveyed hope and motivation to children. For instance, when presenting the songs that Marian used to sing, the words used convey. Moreover, use of colour makes the book
