Factors change Essay Example for Free

Factors change Essay After I have recorded all the results and written into tables, I used the data to make graphs, which are voltage against current. When I finished marking all the points on to the graphs, I put a line of best fit through. There are five graphs in total, each represents a thickness, on a graph there are five lines of best fits, and each represents a length of a thickness. Then I pick a point on the lines of best fits and calculate the gradient (resistance) by dividing the point on y-axis (voltage) by the point on the x-axis (current) as the ohms law states that V=IR. Finally, I have to draw five graphs to show the relations between length (on the x-axis) and resistance (on the y-axis). Also, I have to draw another graph to show the relations between thickness (on the x-axis) and resistance (on the y-axis). Evaluating Although the whole experiment has been going very well, but the results seems to show some bias or errors as in one or two of the graphs, the pattern is quite strange because some of the gradient (resistance) is not proportional to the lengths. Overall, the experiment can be said as a success. The aim of this experiment is to measure how the resistance change as the factors change. There are so many variables-temperature of surroundings, length, thickness, material, temperature of the wire, surface area, magnetic properties, coated or not and purity-that can be chosen to measure in this experiment. But in this experiment I am only going to measure two of them, which are length and thickness because these two are the easiest to measure and show the effects on the resistance. Prediction: The result should be showing that the resistance increase as the length or thickness increase. This happens because when length or thickness increases, the current will decrease. As the voltage wont change, if the current decreases, then the resistance will increase. Method: In the experiment I will need to use apparatus listed below.

Antigone :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  ee cummings once said, â€Å"to be nobody but yourself in a world which is doing its best, night and day, to make you everybody else—means to fight the hardest battle which any human being can fight.† That quotation is exemplified in many works of literature, but the opposite is too. No matter what people try to be or not to be, they don’t always succeed. For example, in the play, Antigone, by Sophocles, the character, Antigone displays the idea of being her own person, but Creon displays the opposite of that.   Ã‚  Ã‚  Ã‚  Ã‚  In the prologue, Antigone tells Ismene that she will do whatever she wants pertaining to their brother, whether or not Ismene agrees and wants to do the same. Antigone tells Ismene, â€Å"If that is what you think, I should not want you, even if you asked to come. You have made your choice, you can be what you want to be.† Antigone displays ee cummings’ thought. The gods want her to think and act a certain way  their laws  but she has her own belief that her brother, Polyneices, should be buried and his spirit should have the proper life, instead of being punished. Even if he was brave, he should be punished. But Antigone doesn’t believe in that. No matter what the consequences, she fights it and does what she thinks is right.   Ã‚  Ã‚  Ã‚  Ã‚  Creon, the king of Thebes, exhibits cummings’ idea. Kings are always supposed to be these big, mighty, terrors that triumph over all and tell their kingdom what to do. Even if Creon did not want to commit someone to demise, he would, because that’s what he’s â€Å"supposed† to do. Creon may be trying to stray from being everyone else, and be his own person, but he’s not succeeding. He is what everyone else wants him to be: a controller over everyone. Creon believes that, â€Å"this is [his] command, and you can see the wisdom behind it. As long as [he is] King, no traitor is going to be honored with the loyal man. But whoever shows by word and deed that he is on the side of the State, --he shall his [Creon’s] respect while he is living, and [his] reverence when he is dead (Scene 1, line 38).† But he doesn’t follow through on that statement. If Creon were to commit someone to his death, he would not give him r espect when he’s dead.

Critical Analysis of Efficiency Market Hypothesis Essay

In this essay, firstly, the Efficient Market Hypothesis (EMH) is given an appraisal in relation to random walk, as well as its definition, revealing theories in context of empirical evidence. A brief explanation of the 3 forms of EMH is highlighted alongside a brief description of its tests for validity. The main focus of discussion is whether or not Technical & Fundamental Analysis can determine abnormal returns by investors strategically using a set of information to formulate buying and selling decisions to beat the efficient market. (Graphs and sets of equations may be applied). Following general empirical studies, the theory of Efficient Market typically asserts that, it would be impossible to consistently outperform the market by means of technical & fundamental analysis, consequently, in the light of this assertion, technical, fundamental and other anomalies are revealed that may suggest some levels of market inefficiencies. Finally, a conclusion, subjectively underlining the relevant points expressed above, putting to perspective facts conveyed through the topic of critical discussion. Appraisal of the Efficient Market Hypothesis and Random Walk The efficient market hypothesis is a financial theory widely accepted by most academic financial economists. It was generally believed that securities markets were extremely efficient in reflecting information about individual stocks and  about the stock market as a whole. The accepted view was that when information arises, the news spreads very quickly and is incorporated into the prices of securities without delay. Thus, when the term ‘efficient market’ was introduced into the economics literature in the 1960s , it was defined as a market in which prices at any time â€Å"fully reflect† and ‘adjusts rapidly to new available information’ (Eugene F. Fama, 1970, p 383.). In the context of this hypothesis, â€Å"efficient† empirically, means that the market is capable of quickly digesting new information on the economy, an industry, or the value of an enterprise and accurately impounding it into securities prices. In such markets, participants can expect to earn no more, nor less, than a fair return for the risks undertaken, hence failing to provide abnormal returns. Random Walk, is a Theory closely associated with the efficient market hypothesis, was originally created by Louis Bachelier (1900), and developed by Kendall, in 1950s. Kendall (1953) found that stock and commodity prices follow a random walk. Random walk varies with regard to the time parameter. According to capital markets theory, the expected return from a security is primarily a function of its risk. The price of the security reflects the present value of its expected future cash flows, which incorporates many factors such as volatility, liquidity, and risk of bankruptcy. However, while prices are rationally based, changes in prices are expected to be random and unpredictable, because new information, by its very nature, is unpredictable. Therefore stock prices are said to follow a Random Walk. Versions of the Efficiency Market Hypothesis and tests Following the concept of information, as stated in the above paragraph, it is useful to distinguish among three versions of the EMH, Fama (1970) identified as: the weak, semi-strong, and strong forms of the hypothesis. These versions differ by their notions of what is meant by the term â€Å"all available information.† The tests for each form, summarized in brief, empirically shows evidence in favor of EMH: According to Fama (1970), Weak form efficiency claims that all past prices of a stock are reflected in today’s stock price. Therefore, technical analysis cannot be used to predict and beat a market. The Weak Form Tests. The test of the weak form of the EMH is generally taken to comprise of; an autocorrelation test, a runs test and  filter rule test. An autocorrelation test investigates whether security returns are related through time. On the other, a runs test, for example, measures the likelihood that a series of two variables is a random occurrence. A filter rule (or trading test) is a trading rule regarding the actions to be taken when shares rise or fall in value by x%. Filter rules should not work if markets are weak form efficient. Overall, the tests highlighted, statistically tests for independence, to establish the weak-form holds, thereby invalidating strategic rules for technical analysis, to obtain abnormal profits. Following the weak-form EMH, is the Semi-Strong form efficiency in which Fama (1970) states that security prices reflect all publicly available information. The Semi-Strong Test. Tests for the semi-strong, significantly and reveals Event Study. The first event study was undertaken by Fama, Fisher, Jensen and Roll (1969), though the first to be published was by Ball and Brown (1968). An event test analyzes the security both before and after an event, such as earnings announcements, stock splits and analyst’s recommendations. The idea behind the event test is that an investor will not be able to reap an above average return by trading, on an event including the Fundamental Analysis strategy.

Essay on The Chief in One flew over the Cuckoo’s Nest by...

One Flew Over the Cuckoo’s Nest Critical Essay One flew over the Cuckoo’s nest, written by Ken Kesey in 1962 is a gripping multidimensional novel, set in an Oregon Mental Institution set deep in the countryside. The novel is narrated by an American half-Indian known as the â€Å"Chief†, who is a seemingly deaf and dumb patient with Paranoid Schizophrenia.
