Childhood in To Kill A Mocking Bird by Harper Lee and Jane Eyre by Charlotte Brontë :: Jane Eyre Essays

The Theme of Childhood in To Kill A Mocking Bird by Harper Lee and Jane Eyre by Charlotte Brontà « 'To Kill A Mocking Bird' by Harper Lee and 'Jane Eyre' by Charlotte Brontà « are two very different books written in different periods of history. There are, however, similarities in the themes and background. For example, both books were written during times of great social upheaval and strife. In 'To Kill A Mocking Bird', the world was still very racist and it was not until some twenty years after the book was written that men like Martin Luther King and Malcolm X started to bring about real reforms. 'Jane Eyre' was slightly different as this was set during a time when the masses of overworked and underpaid Victorians were being given greater freedoms and more time in which to have these freedoms. Both books are written from a first person point of view, with a narrative voice. In 'To Kill A Mocking Bird', the narrative voice is the voice of 'Scout', a small girl and in 'Jane Eyre', Jane herself takes the role of narrator. Both books are also Fictional Autobiographies. This means that they chronicle, if not directly, the lives of the authors. The two books (in the first chapters) revolve strongly around the themes of childhood. The way that these themes are introduced affects the whole book and the way that characters react to one another. 'To Kill A Mocking Bird' starts with two paragraphs that summarize the entire book. It tells the reader of the beginning, middle and end of the book. It also introduces the way in which the story will be told and five of the most important characters. For eight paragraphs, there is nothing but description of the Finch family. It is here that childhood really starts to be introduced. The language used is almost entirely superfluous, very descriptive uses many effective, if childish, techniques such as "There was no hurry, for there was nowhere to go, nothing to buy and no money to buy it with" (repetition) and very descriptive phrases such as "A day was twenty-four hours long but seemed longer". Description of characters is done in two highly differing ways in 'To Kill A Mocking Bird', the first being the adult and formal manner: "Jem and I found our Father satisfactory: he played with us, read to us, and treated us with courteous detachment.

Forecast

Dear Ms. Jones: In order to obtain the forecast for the fifth year we had to gather and analyze the data of the four previous years in your company. The trend (data behaving with the same frequency over the years) that was found was the following: The beginning months of the year are the ones with higher sales. As the months go by, sales continue decreasing until December, where sales come back up again. Now, let me explain how we were able to arrive to this conclusion. First, we calculated the average demand by adding up all the sales of all four years and dividing them by the number of months (48). Then, we came up with the ratio by dividing the sales of each period by the average demand. The seasonal index is then obtained by getting the average of the same month ratios of all four years. For example, the average of all the 4 January ratios. The seasonal index is an average that can be used to compare an actual observation relative to what it would be if we there were no seasonal variation. We arrive to the seasonal forecast by dividing the sales by the seasonal index. Then we get the trend line by adding the intercept plus the x-variable and multiplying that by each period. The trend forecast is what will show you the regular trend of the years. That is obtained by multiplying the trend line times the seasonal index. Here’s a snapshot of the trend of the what the fifth year would look like: And here is another graph showing the trend of the four previous years: As you can tell, the sales behavior repeats itself throughout the years. This trend seems to be very consistent. However, I must warn you that the p-value (percentage defective) in the summary output is significantly higher than . 06, (it is a. 404056) and this means this forecast is not very reliable. I also calculated the percentage errors; the absolute percentage error (MAPE) is 3. 85%. This error was calculated by dividing the absolute error (which we got by subtracting the trend forecast from the sales and using the absolute value of that), by the sales, and then getting the percentage of all the absolute percentage errors. I hope this helps you understand the trend of your sales throughout a year. The most important thing for you to identify is the months where you are having higher sales the possible reasons why those sales decrease as the years comes to an end.
