Miss Julie and Its Preface: The Foundation of a Critical Conflict Essay

  Ã‚     From its first publication and performance, August Strindberg's play "Miss Julie" has been the source of critical controversy and debate. Written in the span of little more than one month in the summer of 1888, the play was banned or censored throughout Europe in the late Nineteenth Century. Because it dealt with situations and attitudes deemed morally or socially offensive (the daughter of an aristocrat seduces her father's valet, and he, in turn, coerces her to commit suicide) the initial negative reaction to the play was rooted in generalized, fanatical, self righteous outrage and did not seek to deal with or engage the text in any specific manner. Instead, "Miss Julie" was a convenient target, symptomatic of all that was corrupting and dangerous in an increasingly progressive world. By the early Twentieth Century, however, more focused moral and artistic critiques were leveled at Strindberg's self proclaimed naturalistic tragedy, a discussion that continues to thrive even today. Though some of the moral and social issues may have lost their radical edge in later decades, there is still an ongoing, lively, and deeply divided debate.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This is not to suggest that these modern critical concerns have forged superior or even different links with the past or to this piece of literature. On the contrary, I would submit that Strindberg himself, as a literary critic of his own work, established (consciously or unconsciously) the fundamental guidelines and ground rules for the interpretive controversies that have followed.   By creating a dynamic tension between his theoretical, essentially pragmatic intentions in his "Preface to Miss Julie" and his creative achievements in " Miss Julie" itself, Strindberg's e... ...wledge our inquiry provides centers around the critical orientation of each voice sounded in the debate.    Works Cited Henderson Archibald.

Chapter 18 Moony, Wormtail, Padfoot, and Prongs

It took a few seconds for the absurdity of this statement to sink in. Then Ron voiced what Harry was thinking. â€Å"You're both mental.† â€Å"Ridiculous!† said Hermione faintly. â€Å"Peter Pettigrew's dead!† said Harry. â€Å"He killed him twelve years ago!† He pointed at Black, whose face twitched convulsively. â€Å"I meant to,† he growled, his yellow teeth bared, â€Å"but little Peter got the better of me†¦not this time, though!† And Crookshanks was thrown to the floor as Black lunged at Scabbers; Ron yelled with pain as Black's weight fell on his broken leg. â€Å"Sirius, NO!† Lupin yelled, launching himself forwards and dragging Black away from Ron again, â€Å"WAIT! You can't do it just like that — they need to understand — we've got to explain –â€Å" â€Å"We can explain afterwards!† snarled Black, trying to throw Lupin off. One hand was still clawing the air as it tried to reach Scabbers, who was squealing like a piglet, scratching Ron's face and neck as he tried to escape. â€Å"They've — got — a — right — to — know — everything!† Lupin panted, still trying to restrain Black. â€Å"Ron's kept him as a pet! There are parts of it even I don't understand, and Harry — you owe Harry the truth, Sirius!† Black stopped struggling, though his hollowed eyes were still fixed on Scabbers, who was clamped tightly under Ron's bitten, scratched, and bleeding hands. â€Å"All right, then,† Black said, without taking his eyes off the rat. â€Å"Tell them whatever you like. But make it quick, Remus. I want to commit the murder I was imprisoned for†¦Ã¢â‚¬  â€Å"You're nutters, both of you,† said Ron shakily, looking round at Harry and Hermione for support. â€Å"I've had enough of this. I'm off.† He tried to heave himself up on his good leg, but Lupin raised his wand again, pointing it at Scabbers. â€Å"You're going to hear me out, Ron,† he said quietly. â€Å"Just keep a tight hold on Peter while you listen.† â€Å"HE'S NOT PETER, HE'S SCABBERS!† Ron yelled, trying to force the rat back into his front pocket, but Scabbers was fighting too hard; Ron swayed and overbalanced, and Harry caught him am pushed him back down to the bed. Then, ignoring Black, Harry turned to Lupin. â€Å"There were witnesses who saw Pettigrew die,† he said. â€Å"A whole street full of them†¦Ã¢â‚¬  â€Å"They didn't see what they thought they saw!† said Black savagely, still watching Scabbers struggling in Ron's hands. â€Å"Everyone thought Sirius killed Peter,† said Lupin, nodding. â€Å"I believed it myself — until I saw the map tonight. Because the Marauder's map never lies†¦Peter's alive. Ron's holding him, Harry.† Harry looked down at Ron, and as their eyes met, they agreed, silently: Black and Lupin were both out of their minds. Their story made no sense whatsoever. How could Scabbers be Peter Pettigrew? Azkaban must have unhinged Black after all — but why was Lupin playing along with him? Then Hermione spoke, in a trembling, would-be calm sort of voice, as though trying to will Professor Lupin to talk sensibly. â€Å"But Professor Lupin†¦Scabbers can't be Pettigrew†¦it just can't be true, you know it can't†¦Ã¢â‚¬  â€Å"Why can't it be true?† Lupin said calmly, as though they were in class, and Hermione had simply spotted a problem in an experiment with Grindylows. â€Å"Because†¦ because people would know if Peter Pettigrew had been an Animagus. We did Animagi in class with Professor McGonagall. And I looked them up when I did my homework — the Ministry of Magic keeps tabs on witches and wizards who can become animals; there's a register showing what animal they become, and their markings and things†¦and I went and looked Professor McGonagall up on the register, and there have been only seven Animagi this century, and Pettigrew's name wasn't on the list.† Harry had barely had time to marvel inwardly at the effort Hermione put into her homework, when Lupin started to laugh. â€Å"Right again, Hermione!† he said. â€Å"But the Ministry never knew that here used to be three unregistered Animagi running around Hogwarts.† â€Å"If you're going to tell them the story, get a move on, Remus,† said Black, who was still watching Scabbers's every desperate move. â€Å"I've waited twelve years, I'm not going to wait much longer.† â€Å"All right†¦but you'll need to help me, Sirius,† said Lupin, â€Å"I only know how it began†¦Ã¢â‚¬  Lupin broke off. There had been a loud creak behind him. The bedroom door had opened of its own accord. All five of them stared at it. Then Lupin strode toward it and looked out into the landing. â€Å"No one there†¦Ã¢â‚¬  â€Å"This place is haunted!† said Ron. â€Å"It's not,' said Lupin, still looking at the door in a puzzled way. â€Å"The Shrieking Shack was never haunted†¦The screams and howls the villagers used to hear were made by me.† He pushed his graying hair out of his eyes, thought for a moment then said, â€Å"That's where all of this starts — with my becoming a werewolf, None of this could have happened if I hadn't been bitter†¦and if I hadn't been so foolhardy†¦Ã¢â‚¬  He looked sober and tired. Ron started to interrupt, but Hermione, said, â€Å"Shh!† She was watching Lupin very intently. â€Å"I as a very small boy when I received the bite. My parents tried everything, but in those days there was no cure. The potion that Professor Snape has been making for me is a very recent discovery. It makes me safe, you see. As long as I take it in the week, preceding the full moon, I keep my mind when I transform†¦I'm able to curl up in my office, a harmless wolf, and wait for the moon to wane again. â€Å"Before the Wolfsbane Potion was discovered, however, I became a fully fledged monster once a month. It seemed impossible that I would be able to come to Hogwarts. Other parents weren't likely to want their children exposed to me. â€Å"But then Dumbledore became Headmaster, and he was sympathetic. He said that as long as we took certain precautions, there was no reason I shouldn't come to school†¦.† Lupin sighed, and looked directly at Harry. â€Å"I told you, months ago, that the Whomping Willow was planted the year I came to Hogwarts. The truth is that it was planted because I came to Hogwarts. This house† — Lupin looked miserably around the room, — â€Å"the tunnel that leads to it — they were built for my use. Once a month, I was smuggled out of the castle, into this place, to transform. The tree was placed at the tunnel mouth to stop anyone coming across me while I was dangerous.† Harry couldn't see where this story was going, but he was listening raptly all the same. The only sound apart from Lupin's voice was Scabbers's frightened squeaking. â€Å"My transformations in those days were — were terrible. It is very painful to turn into a werewolf. I was separated from humans to bite, so I bit and scratched myself instead. The villagers heard the noise and the screaming and thought they were hearing particularly violent spirits. Dumbledore encouraged the rumor†¦Even now, when the house has been silent for years, the villagers don't dare approach it†¦.† â€Å"But apart from my transformations, I was happier than I had ever been in my life. For the first time ever, I had friends, three great friends. Sirius Black†¦Peter Pettigrew†¦and, of course, your father, Harry — James Potter.† â€Å"Now, my three friends could hardly fail to notice that I disappeared once a month. I made up all sorts of stories. I told them my mother was ill, and that I had to go home to see her†¦I was terrified they would desert me the moment they found out what I was. But of course, they, like you, Hermione, worked out the truth†¦.† â€Å"And they didn't desert me at all. Instead, they did something for me that would make my transformations not only bearable, but the best times of my life. They became Animagi.† â€Å"My dad too?† said Harry, astounded. â€Å"Yes, indeed,† said Lupin. â€Å"It took them the best part of three years to work out how to do it. Your father and Sirius here were the cleverest students in the school, and lucky they were, because the Animagus transformation can go horribly wrong — one reason the Ministry keeps a close watch on those attempting to do it. Peter needed all the help he could get from James and Sirius. Finally, in our fifth year, they managed it. They could each turn into a different animal at will.† â€Å"But how did that help you?† said Hermione, sounding puzzled. â€Å"They couldn't keep me company as humans, so they kept me company as animals,† said Lupin. â€Å"A werewolf is only a danger to people. They sneaked out of the castle every month under James's Invisibility Cloak. They transformed†¦Peter, as the smallest, could slip beneath the Willow's attacking branches and touch the knot that freezes it. They would then slip down the tunnel and join me. Under their influence, I became less dangerous. My body was still wolfish, but my mind seemed to become less so while I was with them.† â€Å"Hurry up, Remus,† snarled Black, who was still watching Scabbers with a horrible sort of hunger on his face. â€Å"I'm getting there, Sirius, I'm getting there†¦well, highly exciting possibilities were open to us now that we could all transform. Soon we were leaving the Shrieking Shack and roaming the school grounds and the village by night. Sirius and James transformed into such large animals, they were able to keep a werewolf in check. I doubt whether any Hogwarts students ever found out more about the Hogwarts grounds and Hogsmeade than we did†¦ And that's how we came to write the Marauder's Map, and sign it with our nicknames. Sirius is Padfoot. Peter is Wormtail. James was Prongs.† â€Å"What sort of animal –?† Harry began, but Hermione cut him off. â€Å"That was still really dangerous! Running around in the dark with a werewolf! What if you'd given the others the slip, and bitten somebody?† â€Å"A thought that still haunts me,† said Lupin heavily. â€Å"And there were near misses, many of them. We laughed about them afterwards. We were young, thoughtless — carried away with our own cleverness.† â€Å"I sometimes felt guilty about betraying Dumbledore's trust, of course†¦he had admitted me to Hogwarts when no other headmaster would have done so, and he had no idea I was breaking the rules he had set down for my own and others' safety. He never knew I had led three fellow students into becoming Animagi illegally. But I always managed to forget my guilty feelings every time we sat down to plan our next month's adventure. And I haven't changed†¦Ã¢â‚¬  Lupin's face had hardened, and there was self-disgust in his voice. â€Å"All this year, I have been battling with myself, wondering whether I should tell Dumbledore that Sirius was an Animagus. But I didn't do it. Why? Because I was too cowardly. It would have meant admitting that I'd betrayed his trust while I was at school, admitting that I'd led others along with me†¦and Dumbledore's trust has meant everything to me. He let me into Hogwarts as a boy, and he gave me a job when I have been shunned all my adult life, unable to find paid work because of what I am. And so I convinced myself that Sirius was getting into the school using dark arts he learned from Voldemort, that being an Animagus had nothing to do with it†¦so, in a way, Snape's been right about me all along.† â€Å"Snape?† said Black harshly, taking his eyes off Scabbers; for the first time in minutes and looking up at Lupin. â€Å"What's Snape got to do with it?† â€Å"He's here, Sirius,† said Lupin heavily. â€Å"He's teaching here as well.† He looked up at Harry, Ron, and Hermione. â€Å"Professor Snape was at school with us. He fought very hard against my appointment to the Defense Against the Dark Arts job. He has been telling Dumbledore all year that I am not to be trusted. He has his reasons†¦you see, Sirius here played a trick on him which nearly killed him, a trick which involved me –â€Å" Black made a derisive noise. â€Å"It served him right,† he sneered. â€Å"Sneaking around, trying to find out what we were up to†¦hoping he could get us expelled†¦.† â€Å"Severus was very interested in where I went every month.† Lupin told Harry, Ron, and Hermione. â€Å"We were in the same year, you know, and we — er — didn't like each other very much. He especially disliked James. Jealous, I think, of James's talent on the Quidditch field†¦anyway Snape had seen me crossing the grounds with Madam Pomfrey one evening as she led me toward the Whomping Willow to transform. Sirius thought it would be — er — amusing, to tell Snape all he had to do was prod the knot on the tree trunk with a long stick, and he'd be able to get in after me. Well, of course, Snape tried it — if he'd got as far as this house, he'd have met a fully grown werewolf — but your father, who'd heard what Sirius had done, went after Snape and pulled him back, at great risk to his life†¦Snape glimpsed me, though, at the end of the tunnel. He was forbidden by Dumbledore to tell anybody, but from that time on he knew what I was†¦.† â€Å"So that's why Snape doesn't like you,† said Harry slowly, â€Å"because he thought you were in on the joke?† â€Å"That's right,† sneered a cold voice from the wall behind Lupin. Severus Snape was pulling off the Invisibility Cloak, his wand pointing directly at Lupin.

Alcohol and substance abuse Essay

Introduction There are many challenges facing the world today raging from political conflicts (wars), natural disasters, famine, diseases, economic and social problems among others. Every continent on this earth and for that matter every country have encountered one or more of such problems. However some countries have been able to eradicate or minimize the occurrence and effect of some these problems such as famine, economic issues, political conflicts etc. Usually, developing countries in Asia, Africa and Latin America are the most vulnerable to all these problems. Apart from natural disasters which its occurrence can hit any country, developed countries encounter minimal problems of famine , political or economic problems but are often challenged with especially social problems including substance abuse mainly alcohol usage. What is Substance Abuse Substance abuse have been one of mankind oldest weakness as we have as human beings, in one way or the other either consciously or unconsciously have abuse some sort of substances at a particular point in time of our life. In ancient Greece, were a group of people called â€Å"lotus eaters† where they used lotus fruits and flowers as form of food which put them in some form of hallucinogenic state. Substance abuse is the use of illegal drugs or the excessive use of legal substance so as to produce physical, psychological or social harm. The World Health Organization refers to substance abuse as harmful or hazardous use of psychoactive substances including alcohol and illicit drugs. Substance abuse which is commonly referred to as drug abuse is therefore the use of illegal or in appropriate use of a legal substance that alter the normal functioning of the brain or nervous system and are harmful to the general health of the user. (Levin et al 2000, WHO 2010) Substance Abuse in the Context of Alcohol Alcohol is a form of liquid known as ethanol and used as an ingredient or a constituent of intoxicating beverages such as beer, spirits, wine and other drinks. Alcohol is the most prevalent psychoactive substance used by many people. It is often used as a form of depressant which as a result slow the effective performance or operation of the central nervous system. Substance abuse drugs are categorized as stimulants (caffeine, nicotine), depressant (alcohol, valium), hallucinogens (ecstasy, LSD), cannabis (hashish, marijuana) and steroids (Macionis 2005, WHO 2010). Why people use alcohol There are number of reasons why people use alcohol. Curiosity among other reasons such as for recreational, spiritual, psychological, social conformity etc. are often the explanation given. Some of these reasons are not obvious and most people use different forms of excuses like, I have had a stressful day or week, I have friends coming around, I have to get in the mood to socialize etc. Recreational and Spiritual People see alcohol consumption as a form of leisure. Example, some people may drinking a glass of wine or beer before, after or with a meal to increase their appetite, make the food taste better or make them more relaxed. Many cultures around the world use alcohol in their spiritual practices and believes. In Ghana and other African countries, often alcohol is used as a form of offering in pouring libation to the gods. Psychological and Social Conformity Due to the psychoactive effect of alcohol, it is seen as a way of alleviating stress, mental and emotional problems. Some people use alcohol due to a particular society, group, affiliation etc. that they belong to in other to fit in. During social events, alcohol are usually served and many people believe by consuming alcohol will instill a sense of confidence when in the company of others. Example is among college students and young adolescent where due to peer pressure find themselves drinking alcohol. People living in isolation with poor network support and decrease mobility may often turn to alcohol especially among senior citizens. Alcohol and other substance abuse as a problem In most societies, people have different opinions and mixed feelings about alcohol and other forms of substance abuse. Some people may consider its use as beneficial while others may disagree. However, the problems created by alcohol and other substance abuse are staggering than the benefits derived. The most commonly problems we often witness are public drunkenness, disorderly behavior, traffic and industrial accidents, broken families, crime, poor social functioning and worsening of existing conditions such as poverty, mental and physical illness. (Kornblum and Julian 1974). Key findings indicated that more people suffer from alcohol use disorders compare to drug use and both types are common in men than in women. In every year 35 out of 100,000 people are killed by alcohol where as in 2012 3. 3 million deaths were attributed to alcohol consumption globally. 5. 4% of world’s annual disease burden is caused by alcohol and illicit drug use, whereas tobacco accounted for 3. 7%. Globally 46% of all men and 73% of women abstain from alcohol. This means 54% of men and 27% of women of the total global population have at some point in their life consumed alcohol before. Therefore 81% of the total worldwide population have consumed alcohol at some point in time. 6. 2 liters of pure alcohol were consumed per person aged 15 years or older in 2010 worldwide. Developed countries have the highest consumption rate with Europe having the highest level of alcohol consumption while the lowest is found in the South East Asia region (WHO 2014). Effect of Alcohol Alcohol consumption has several negative effect on the user which as a result affect the society, country and the globe. The annual death rate related to alcohol consumption is about 3. 3 million globally. The individual also becomes very vulnerable of contracting other diseases like cirrhosis of the liver, anemia, heart attack etc. Alcohol and other substance users are more exposed to social related harm like rape, accidents, injury or even death. Governments in various countries spend huge sums of money to treat and rehabilitate substance abuser, such individuals sometimes lose earnings, become unemployable or lose their family. The money, time and health care facilities used to rehabilitate these individuals put lot of economic strain on the government budget and even the economical contributions of such individual is even severe if the person is a professional example a medical doctor, teacher, IT technician etc. Such monies could be used to do other social economic developments to improve the overall wellbeing of the society and the globe. The Finnish government spend about 1. 3 billion euros annually for managing alcohol related problems according to the National Institute for Health and Welfare (Yle News 2013, WHO 2014). Conclusion Alcohol and other substance abuse is not an individualistic problem but a worldwide issue where all governments must work together to combat, reduce, if not eradicate the total consumption of it. Good policies on better health care systems, improved economic policies and strong but encouraged social living programs should be implemented. Efficient advocacy programs, effective regulatory strategies and the involvement of community base action programs to care, support and prevent the sale and consumption of alcohol and other substance abuse materials should be implemented and encourage.

Scarlet Letter- Pearl Pyrnne essays

Scarlet Letter- Pearl Pyrnne essays Pearl Prynne, Is She Older Then She Seems Or Just An Elfish Child? See ye not, this is the scarlet letter, only capable of being loved, and so endowed with a millionfold the power of retributation for my sin? (Hawthorne pg. 109) Critics have suggested that Pearl did not always act the way other children might have been known to and I agree with this. Using details from the book, and other resources, the following paragraphs will look further into Pearls social behavior, different moods, and personal relationships with other characters. In The Scarlet Letter, Pearl had no childhood friends. She was born an outcast and even at an early age, seemed to know that she didnt fit in. One example of her maturity in society was If the children gathered about her, as they sometimes did, Pearl would grow positively terrible in her puny wrath, snatching up stones to fling at them. (Hawthorne pg. 90) This action not only showed her defending herself but also protecting her mother. Hester was the town gossip and the outcast as well as Pearl. Since birth, Pearl had sensed she was not supposed to fit in. When children talked to her, she would never talk back, but when she was picked on she wouldnt think twice to hold her ground. Not only was she wise in this way but very independent and strong. You can tell that Pearl was not always well behaved but quite clever. When she was young, she had quite an imagination. After putting her fingers in her mouth, with many ungracious refusals to answer good Mr. Wilsons question, the child finally announced that she had not been made at all, but had been plucked off the bush of wild roses that grew by the prison door. (Hawthorne pg. 108) She was only around three years old here and if you think of your average three year old, Pearl would be quite different by comparison. She might have thought of the Governor as a threat because it was said that sh...

Purify Alcohol or Denatured Ethanol Using Distillation

Purify Alcohol or Denatured Ethanol Using Distillation Denatured alcohol is toxic to drink and may be unsuitable for some lab experiments or other purposes. If you need pure ethanol (CH3CH2OH), you can purify denatured, contaminated or impure alcohol using distillation.   Alcohol Distillation Materials Balance100-mL volumetric flask or graduated cylinderDistillation apparatus250-mL beaker (or another container to receive the distilled alcohol)Hotplate or another flameless heat source (to avoid igniting the ethanol)Boiling chips200-mL impure ethanol (e.g., 70% denatured alcohol) You can also  make  a distillation apparatus if you dont already have one or arent sure what one looks like. Alcohol Distillation Procedure Put on appropriate safety gear, including goggles, gloves and protective clothing.Weigh the volumetric flask or graduated cylinder and record the value. This will help you determine your yield if you care to calculate it.Add 100.00 mL of alcohol to the volumetric flask. Weigh the flask plus alcohol and record the value. Now, if you subtract the mass of the flask from this value, you will know the mass of your alcohol. The density of your alcohol is the mass per volume, which is the mass of the alcohol (the number you just obtained) divided by the volume (100.00 mL). You now know the density of the alcohol in g/mL.Pour the ethanol into the distillation vessel and add the remaining alcohol.Add a boiling chip or two to the flask.Assemble the distillation apparatus. The 250-mL beaker is your receiving vessel.Turn on the hotplate and heat the ethanol to a gentle boil. If you have a thermometer in the distillation apparatus, youll see the temperature climb and then stabilize when it reache s the temperature of the ethanol-water vapor. Once you reach it, do not allow the temperature to exceed the stable value. If the temperature starts to climb again, it means the ethanol is gone from the distillation vessel. At this point, you could add more of the impure alcohol, if it didnt all fit in the container at the start. Continue distillation until you have collected at least 100 mL in the receiving beaker.Allow the distillate (liquid you collected) to cool to room temperature.Transfer 100.00 mL of this liquid into the volumetric flask, weigh the flask plus alcohol, subtract the weight of the flask (from earlier), and record the mass of the alcohol. Divide the mass of the alcohol by 100 to get the density of your distillate in g/mL. You can compare this value against a table of values to estimate the purity of your alcohol. The density of pure ethanol around room temperature is 0.789 g/mL.If you want, you can run this liquid through another distillation to increase its purity. Keep in mind, some alcohol is lost during every distillation, so youll have a lower yield with the second distillation and even less final product if you do a third distillation. If you double or triple distill your alcohol, you can determine its density and estimate its purity using the same method outlined for the first disti llation. Notes About Alcohol Ethanol is sold in the pharmacy sections of stores as a disinfectant. It may be called ethyl alcohol, ethanol or ethyl rubbing alcohol. Another common type of alcohol used for rubbing alcohol is isopropyl alcohol or isopropanol. These alcohols have different properties (notably, isopropyl alcohol is toxic), so if it matters which one you need, be sure the desired alcohol is listed on the label. Hand sanitizer gels also often use ethanol and/or isopropanol. The label should list which type of alcohol is used under the active ingredients. Notes About Purity Distilling denatured alcohol will remove enough impurities for may lab applications. Further purification steps could include passing the alcohol over activated carbon. This would be especially helpful if the point of the distillation is to obtain drinkable ethanol. Be very careful distilling ethanol to drink using denatured alcohol as a source. If the denaturing agent was simply an additive intended to make the alcohol bitter, this purification might be fine, but if toxic substances were added to the alcohol, a lesser degree of contamination may remain in the distilled product. This is especially likely if the contaminant had a boiling point close to that of the ethanol. You can reduce contamination by discarding the first bit of ethanol that is collected and the last portion. It also helps to tightly control the temperature of the distillation. Just be aware: distilled alcohol is not suddenly pure! Even commercially produced ethanol still contains traces of other chemicals.

Moving Average Calculations Essay Example | Topics and Well Written Essays - 500 words

Moving Average Calculations - Essay Example B., â€Å"Technical Analysis from A to Z†). Simple Moving Average is one of the most important methods utilized for the calculation of moving average. It is denoted by SMA. It is calculated by measuring the average concluding price of a stock along with large number of time periods. It is one of the simple types of moving averages. It mainly includes two different parameters such as ‘period’ and ‘cost’. Moreover, in most of the times, the total number of periods is calculated along with closing value of the stocks. The formula used for the calculation of simple moving average is , where n denotes the number of time periods and Pn is the cost or price required to calculate SMA. The prime benefit of SMA is that it is quite an easy method and is used by most of the traders all over the world (Achelis, S. B., â€Å"Technical Analysis from A to Z†). Exponential Moving Average is the other important practice utilized for calculation of moving average. It is also denoted as EMA. It is almost similar to SMA except the average is calculated with the help of the most recent price. It is the only reason that many scientific analysts prefer using EMA rather than SMA for examination. The formula utilized for the calculation of EMA is: EMA (current) = ((Price (current) – EMA (prev)) x Multiplier) + EMA (prev). The value of EMA changes with alterations in the number of periods which is denoted by ‘multiplier’. Moreover, the method of EMA is also beneficial as it offers the most exact value. Apart from these, it only requires the previous days average value rather than the data of entire phase. Thus, it is more advantageous than SMA (Achelis, S. B. â€Å"Technical Analysis from A to Z†). A Weighted Moving Average is also the other vital practice utilized for the calculation. It is also a quite well known method. It is denoted as WMA. A weighted moving average provides more importance

The Iraq War 2003 in Western media and public opinion Essay

The Iraq War 2003 in Western media and public opinion - Essay Example Although opinion polls indicated a shift in the British public opinion about the war, the public opinion did not actually change during the entire period. Though the polls conducted by different agencies in the UK indicated an increase in the level of support for the war, it did not reflect the true opinion of the public. The public opinion only appeared to change because of the shortfalls in the polling process. In any opinion poll, there are priority issues that can alter the respondents’ answer depending on the way they are presented. If such priority issues are overshadowed by time or other events, the pollsters can ignore them in subsequent polls. For instance, in the British case, the pollsters left out the key issues because of time and other events that had occurred. Thus, if it were possible to incorporate the key events in the polls disregarding other events that had occurred, the polls could have otherwise suggested a different result. Apart from ignoring the real i ssues that initially determined people’s attitude, opinion polls possibly misidentified the respondents’ support for related issues as the support of the war. For instance, a respondent could have identified with one side of the conflict for personal reasons without necessarily supporting the war. In such situation, the polls deceptively indicated the support of the war. As a result, the outcome became unreliable. According to Baines and Worcester (2005), the public opinion changed during the war because of three major reasons.
