The Man of the House Essay Example for Free

The Man of the House Essay The Man of the House The book Angela’s Ashes by Frank McCourt is about a young man that retells his childhood, when he and his family move from America to Ireland. Throughout the book the three main characters are Angela Mc Court (Frank’s mother), Malachy Mc Court (Frank’s father), and himself. All three of the characters play a very important role in the book, and they also affect each other. The most complex character of the book is Frank. Frank is not only the protagonist of this book, but he is also able to express all of his feelings in all the situations he goes through, throughout this book. Frank is the most variegated character in this book. He is the one that has to deal with not only his problems but everyone else’s. As the book continues the protagonist, Frank is growing up to be a man by himself (324). Usually boys have fathers that help them grow up into mature men, but Frank never was able to have that. His father was out drinking, not worrying what was going to happen with his family, and being irresponsible and selfish, which is what happens to a person when they have an addiction. When his father abandons the family, the weight is then put on Frank to take care of his siblings and mother. He is then put in the spot of â€Å"the man of the house†. Frank doesn’t mind getting a job at all, in fact he rather get a job then get an education (261). He likes the idea of working because when you work you see the result right away, which is money, but when getting an education your reward is more long term than short term. He sees this as a responsibility, but he also looks forward to being a man, and bringing home the wages his father was never able to do (265). Frank goes through this struggle throughout the book, becoming a man without his father, but he also has a hard time with his religion. Frankie, at this point, goes back and forth with Catholicism. His whole family is catholic and he believes in God, but there has been so many times where the Catholic Church has shut the doors on him. All of the experiences that Frank has had with the church do not make him think of his Irish religion as a positive thing. Frank mentions that when he is out being the messenger boy the poor people of Limerick are the ones who will tip him exceptionally well, the wealthy people on the other hand, the nuns, and the priests do not tip at all (315). Mentioned  throughout the book are the sins that Frank makes, all of the sins he makes guilt him, and they just get worse as the time goes on. Frank, as any other protagonist, goes through a long journey that makes him the man that he grows into by the end of the book. He goes through many obstacles, which is why I think he is the most complex character. Frankie makes the most progress, he has a goal that he makes early in the book, and that is to go back to America, which he later on succeeds at doing. He keeps determination that comes from within, but from also people around him that believe in him and what he is capable of doing.

A Separation of Life :: essays research papers

Water, the median of life. Growing up in a small town nestled tightly in the arms of the wasatch front, I learned early the importance of nature. There was a fine line drawn between religion and the outdoors, and the quest of my life was to determine an appropriate balance. Water, signifying the line between the spiritual and physical, played an important role in my secular teachings. Cutting through the center of town it was the very phenomenon that I had grown to love, the river. Soul restored and imagination stirred, the words of the river echoed the marks of God. Although by nature I stood alone, untutored and untouched, the waters of life left me free to understand the natural side of God’s order. With its flowing properties and unbridled passion to move forward, the water was my spirit. An old weathered palm tree emerged from the seemingly impenetrable sandy beach. I leaned back against its rough surface as the waves of the emerald blue ocean slowly crawled to my feet. They lapped relentlessly against the shore as if trying to take me back with them. The wind blew gently over the top of the distant incoming waves as they mirrored back the competing rays of sun. With each reflection, I narrowly squinted my eyes and continued to marvel at this picturesque interaction of color and beauty. I raised my hand to my brow, wiping off the beads of sweat that saturated my face. As my fingers moved across my sensitive skin, I could tell the sun had left its mark. I felt their was no escaping the blanket of rays only the clouds above seemed to be able to control. The pain was uncomfortable, but disappeared quickly as I scooped up the cool water and splashed it on my face. I knew that I could not drink the seemingly infinite volume of water which surrounded me, so I headed for a nearby stream. Kneeling down, I penetrated the stream with cupped hands and raised the fresh water to my dry lips. I was unable to control the water as it sifted through my fingers and ran down my arms, as if trying to escape back to the stream. I licked my salty lips and drank. I had never before tasted a more refreshing drink of water. This euphoric experience was one that I savored, as I reached for a second handful. There have been few experiences throughout my life that I remember more vividly than of that day on the beach. I often think about where the water would flow, and who would be the recipient of its aqueous forgiveness.

Parametric and Nonparametric Methods in Statistics

There are a few divisions of topics in statistics. One division that quickly comes to mind is the differentiation between descriptive and inferential statistics. There are other ways that we can separate out the discipline of statistics. One of these ways is to classify statistical methods as either parametric or nonparametric. We will find out what the difference is between parametric methods and nonparametric methods.  The way that we will do this is to compare different instances of these types of methods. Parametric Methods Methods are classified by what we know about the population we are studying.  Parametric methods are typically the first methods studied in an introductory statistics course. The basic idea is that there is a set of fixed parameters that determine a probability model. Parametric methods are often those for which we know that the population is approximately normal, or we can approximate using a normal distribution after we invoke the central limit theorem.  There are two parameters for a normal distribution: the mean and the standard deviation. Ultimately the classification of a method as parametric depends upon the assumptions that are made about a population. A few parametric methods include: Confidence interval for a population mean, with known standard deviation.Confidence interval for a population mean, with unknown standard deviation.Confidence interval for a population variance.Confidence interval for the difference of two means, with unknown standard deviation. Nonparametric Methods To contrast with parametric methods, we will define nonparametric methods. These are statistical techniques for which we do not have to make any assumption of parameters for the population we are studying. Indeed, the methods do not have any dependence on the population of interest. The set of parameters is no longer fixed, and neither is the distribution that we use.  It is for this reason that nonparametric methods are also referred to as distribution-free methods. Nonparametric methods are growing in popularity and influence for a number of reasons. The main reason is that we are not constrained as much as when we use a parametric method.  We do not need to make as many assumptions about the population that we are working with as what we have to make with a parametric method. Many of these nonparametric methods are easy to apply and to understand. A few nonparametric methods include: Sign test for population meanBootstrapping techniquesU test for two independent meansSpearman correlation test Comparison There are multiple ways to use statistics to find a confidence interval about a mean.  A parametric method would involve the calculation of a margin of error with a formula, and the estimation of the population mean with a sample mean.  A nonparametric method to calculate a confidence mean would involve the use of bootstrapping. Why do we need both parametric and nonparametric methods for this type of problem? Many times parametric methods are more efficient than the corresponding nonparametric methods. Although this difference in efficiency is typically not that much of an issue, there are instances where we do need to consider which method is more efficient.
