Who Do I Admire Essay Example for Free

Who Do I Admire Essay Most of the people have somebody who they admire, that person can be a writer, an artist, a politician, some kind of public figure, a celebrity or even a friend. But that person who I admire is somebody very close to me, that person is my father. My father is not a great scientific, politician, artist or something like that. Neither has done something big to the society. He’s just a normal father and a good one by the way. So, you may ask yourselves, that if he hasn’t done anything special, why would you admire him? Well, to understand better about the reason why I admire him, I’m going to tell you about his life. My dad was born in La Romana in the 1970’s, since he was born he was raised in a poor environment, but besides that he had a lack of his parents love and support. That means he didn’t have an easy childhood. Even though his parents weren’t such good parents that didn’t affect much my father, because he at least had support of some people of his family. My father since he was a kid had dreams and goals, like most of the people do. But to fulfill one of his goals, he needed to study and graduate from high school. The problem is that his family didn’t have enough money to pay a student expenses. But my father didn’t let anything to stop him to fulfill he’s goals so he being a kid started to work as a shoe shiner to earn money by his own just to pay the school expenses. While years were passing by, my father was maturing faster than any other person of his age, due to the situation he was living. His high school graduation day came, and he had the will to continue developing in his studies, he wanted to go to the university to become a professional and so to be able to reach one of his goals. Since he was a poor person without the necessary resources to pay a university, he needed to ask help. He asked for any help to his familiars and friends, but nobody could help him, and he decided to ask his father. Unfortunately his father didn’t want to provide him any help to be able to continue his studies and he could never go to the university. Even that occurred, that never stopped my dad. His will was strong, he demanded himself to be able to progress and to continue forward. He searched for better job opportunities in one of his brothers’ company. There he got a job being a truck driver. But he didn’t want to stay as one. With time and hard work, he could obtain a better position in the company; he managed up to be the manager of the company. With his hard work and perseverance he became independent. He started his own company, and continued working. Now days, he has a company in his hometown and a branch in Higuey where he’s living today. As you’ve been listening, you know now that my father has not lived an easy and joyful life. Since his childhood he has been working to become someone important in life. Though my father grew up without the love of his parents, he never acted the same with his family. He has been an excellent father, I can’t complain about nothing. He worries a lot about his family, in every sense. He wants us to live like he wished he could live, giving my mother, my sister and I those things he could never have, and gives us that support he never received. My dad is an excellent father, a good businessman, in overall a great person. I have known a lot of people, and I have not seen anyone as my father. I don’t know if he has become someone big and important in life. But I can say that he has really become the most important person in mine. Maybe I don’t know who you admire. But I think you have heard enough to understand why my dad is the person who I admire.

Reversing Stroke and Spinal Cord Damage :: Biology Essays Research Papers

Reversing Stroke and Spinal Cord Damage Scientists are on the brink of doing the unthinkable-replenishing the brains of people who have suffered strokes or head injuries to make them whole again. If that is not astonishing enough, they think they may be able to reverse paralysis. The door is at last open to lifting the terrifying sentence these disorders still decree-loss of physical function, cognitive skills, memory, and personality. Until recently there was virtually nothing doctors could do for the 500,000 Americans who have strokes each year, the 500,000 to 750,000 who experience severe head injury, or the 10,000 people who are paralyzed after spinal cord damage (3). However, that is about to change. Researchers now think it may be possible to replace destroyed brain cells with new ones to give victims of stroke and brain injury a chance to relearn how to control their body, form new thinking processes, and regain emotions. After demolishing the long-standing myth that brain cells cannot regenerate or proliferate, scientists are developing ways to stimulate cells to do just that. Although stroke, head injury, and paralysis are three of the most devastating things that can happen to anyone, scientists have recently learned that the damage they cause is not preordained. It takes place over minutes, hours, and days, giving them a precious opportunity to develop treatments to halt much of the damage. Most of the n ew remedies are not yet available, but an explosion of research in the last five to ten years has convinced scientists that some of them will work (8). Guided by fabulous results in preventing permanent damage from stroke and other injuries to the central nervous system in rats and other animals, researchers around the world have launched scores of trials in humans (12). However, many promising new therapies are sitting on the shelf because of a lack of money and other resources necessary to conduct large, lengthy, and expensive studies to conclusively show that a new drug or treatment really works in people. The requirement for safety and efficacy can be frustrating, especially for badly needed treatments that are very promising, but such caution is necessary. One organization is trying to raise funds for a major study to test a pill for paralysis-4 amino pyridine (4 AP) -which has shown promising results in preliminary human trials (14). About half of the small number of people in the study, who had been paralyzed for four to fifteen years, regained some sensation and muscle function when they were given intravenous infusions of 4 AP.

Economy And Interest Rates Could Edge Down By Jon Hilsenrath

In the Wall Street Journal Article â€Å"Fed Forecasts for the Economy and Interest Rates Could Edge Down† the author of the article Jon Hilsenrath wanted to address the future rises of interest rates that are soon to come and the effects that those rises will have on the now growing economy. Recently in the news there has been a great deal of talks of the future rises of interest rates in the United States. To understand how the Fed s own particular figures may change, The Wall Street Journal analyzed how the standpoint among private forecasters had changed since March, when the Fed last upgraded its Summary of Economic Projections. The new 2.1% appraisal is beneath the Fed s 2.5% projection for March and recommends Fed authorities may be bringing down their own numbers when they discharge their new Summary of Economic Projections at the June 16-17 meeting. After Fed authorities move down their projections for premium rates and monetary development in March, speculators reacted by pushing down genuine rates and the estimation of the dollar. Private investigator gauges for unemployment and expansion are minimal changed, and propose the Fed s own figures will be stable on this front in its June forecasting round. The levels they see for the rate 0.6% toward the end of 2015 , 1.8% toward the end of 2016 and 3% toward the end of 2017 are beneath the Fed s anticipated way as of March, and recommend Fed projections may edge down modestly as well.
