Investigating Bubble Wrap as an Insulator Essay Example for Free

Investigating Bubble Wrap as an Insulator Essay Apparatus   Kettle Water   Small Plastic Bag What are we going to do? We are going to experiment for which bubble wrap or bag is the best insulator. We are doing this experiment because to prove my research in the hypothesis. We will test the big bubble wrap, small bubble wrap, a plastic bag and just the steel can. To extend the experiment we will test the bubbles facing inwards and outwards of the steel can. This will be used for the big bubble wrap and small bubble wrap. 1. First we will boil up some water in a kettle. 2. Then, we will measure the 140ml in a measuring cylinder. This is because we wont to know how easily heat energy can escape through the can. 3. We shall pour the 140ml of hot water on the steel can. 4. We will put a plastic lid on top of the can. A thermometer will be put through a pierced hole into the middle of the plastic lid. 5. Later we will measure the temperature. 6. As soon as the temperature falls to 84 degree, we will start the timing. 7. We will record the temperature every minute for 10 minutes. After ten minutes the experiment will be done. 8. We will repeat the experiment to find an average temperature for every minute. 9. Finally we well repeat this experiment for the big bubble wrap facing in and out of the can, the small bubble wrap facing in and out of the can and the plastic bag around the steel can. We have chosen to start every experiment at 84 degrees because we think the water may not reach temperatures as high as 90 degrees. For a fair test we will measure the temperature at every minute to make equal spacing of time between each reading of time. ANALYSIS Apparatus Small Plastic Bag Method In my experiment I kept many of the things I was going to do, the same. But after finding a couple of difficulties in the experiment I had to alter a couple of things. They were:    The process of measuring the hot water. I found out that the temperature of the water decreased rapidly so I could not start the experiment at 84 degrees. So I changed the process of measuring the water. Instead of measuring the water after boiling it up, I measured the water before boiling it up. This meant that I had to put 5ml of extra water in the kettle because a tiny bit of the water would have been evaporated.   Inserting more water into the steel can. I found out that the steel can was not being filled to the top. This meant that the air between the lid and water had been transferring heat energy by convection. I stopped this by adding 10 extra millilitres of water into the steel can. Conclusion In my results table I have observed that the big bubble wrap was the best insulator. The small bubble wrap was a worse insulator than the big bubble wrap and although the plastic bag was the worst insulator, it was the best insulator. The results of the experiment with no covering on the steel can did not fit the graph. This is because the graph showed that the experiment with no covering on the steel can was a good insulator. I would have thought that no covering on the steel can would have helped the heat energy escape. The only explanation for why the graph showed that the experiment was a good insulator is that a big, thick object would have been near the steel can preventing from escaping so easily. In my prediction, I said that the big bubble wrap would be the best insulator. This is because there is a lot gas in each bubble preventing heat energy from escaping so easily. The atoms in a gas are little and very spread out which makes the vibration of one atom to another very hard. I also said that the plastic bag was a good conductor because the heat energy only had go through the steel can and plastic bag. There was not much gas between the steel can and plastic bag together because the plastic bag was close to the steel can. Heat energy can go through a solid easily by conduction because the atoms are close together making the vibrating of each atom easy. This theory has been proved by my results and graph. I decided to record the temperature at every minute in each the experiment, because then I would have a wide range of results of the temperature decreasing. EVALUATION There were some things that were not fair which made the experiment go wrong a little. They were:- 1. The reading of the temperature. Sometimes I would not reading the temperature because the marks on the thermometer were squashed together so I could not read the numbers so easily. If I had a high-tech piece of equipment (e. g. a computer) then I could connect a thermometer to the computer and just read the temperature off the computer. 2. The reading of the temperature APPROXIMATELY every minute. Most of the time I could not read the temperature exactly every minute. Sometimes I was reading the temperature before the minute and sometimes after the minute. This effected my results because some results read the same and some had a big decrease (like the point at the orange circle). I could get solve this problem by also using a computer and connecting a stopwatch to it so the temperature could be given at exactly every minute. 3. The rounding off of a number after being read. Many of the numbers that I read were not whole numbers. So I had to result to rounding the number off. This effected my results because again some results read the same and some had a big decrease. If the thermometer had smaller marks telling you the numbers then I could have precise results. We could result to using a computer. I was not happy with my results with my results for no covering at 1 minute (marked orange circle) because of all the reasons above. These reasons are why my graph a bit out of shape. Although my graph was not accurate, my results were reliable to prove my prediction. My results clearly show that the big bubble wrap was the best insulator (and a bad conductor) and the experiment with the bag was the worst insulator (and a good conductor). I could make my results better by repeating the whole experiment again but this time using all the suggested I have given. If I were to do this then I would get the accurate results and prove that the experiment without covering would be the worst insulator. I would do the experiment three or four times to get a better and more reliable average. My results are not sufficient to prove my conclusion. I think I would have to do the experiment with no covering again to at least make my conclusion right.

Children and the Effects of Television Essay Example for Free

Children and the Effects of Television Essay Television programs were created for children to learn everyday skills, but it can come to start affecting children today because they watch too much they start lacking in physical activity and some can become distant and violent. Studies have shown that children can become obese, violent and even dependent on television if watched too much television. Television can influence children in many different ways like becoming obese, become dependent on it too much; change school habits and even can become violent with watching different types of shows. It is time for parents to start standing up and take control over what and just how much their children watch television. It is said that children watch too much television even though some studies have proven that different types of children’s television shows tend to effect children in different ways also they learn new things faster. Shows like Blue’s Clues, Chuggington, Dinosaur Train, Mickey Mouse Club House, and Team Umizoomi are all filled with educational values that help children develop skills that they need. Blue’s Clues is a much liked show by children ages 2-4. According to Common Sense Media (2012), In fact, Blues Clues does a very fine job of treating its young viewers as the multifaceted individuals that they are.† This is very important to young children because it makes them feel as they are a part of something special when they watch shows like this. With these types of shows teach children how to have different types of important social skills, teamwork, science, alphabet, numbers, math problems and even have physical fitness in them which are some of the things that a child needs to know. With these types of show is just what children need to help them expand their brains. According to PEDÃÅ"K (2012) â€Å"Whichever program it may be, it has behavioral, mental and emotional effects.† (p.224).On the other hand more children are watching more television shows for an entertainment purpose which has no educational vales in them. Shows like Sponge Bob Square Pants, The Simpsons, Batman, and The Teenage Mutant Ninja Turtles which consist of having violence, rudeness, and poor role models for children are the ones that are shaping our children in this day of age. It is up to the parent to make sure that their children are getting the correct balance of fun, education, and physical activity to help them grow. Studies have shown that cartoons have the most major impacts on children because in the cartoons to children it is something done every day and ok to act out likes the character on television. According to Kids Health from Nemours (1995-2012),† Kids who view violent acts are more likely to show aggressive behavior† which has become an issue to many different children around the world today. Children are like little sponges soaking up everything they can because every little boy and girl wants to be like their favorite cartoon hero or character. How much time a child watches television is a major factor in children’s behavior and their physical health. Whenever parents allow their children to sit in front of the television and watch more than four hours a day then parents could be running a risk of their child to become more dependent on television to keep them entertained, and this can become very harmful to a child’s health, or to their mental state as well. It can be hard on a parent try to clean house, cook a meal, and even do school work with children becoming bored, and parents just do not have the time to spend with them and then so it seem to be a helpful tool to be able to help at the time for them to watch television. One of the things that you can do to make sure when the appropriate times and what is the appropriate show’s to watch according to Kids Health from Nemours (1995-2012),† Come up with a family TV schedule that you all agree upon each week. Then, post the schedule in a visible area (e.g., on the refrigerator) so that everyone knows which programs are OK to watch and when. And make sure to turn off the TV when the scheduled program is over instead of channel surfing.† Instead of giving your children television time when they experience boredom some suggestion to them is to go outside and make believe that they are the characters in their favorite learning television show. Another thing is get them some flash cards with math, spelling or any type of learning cards. If you distract children from television with something better then you will have a child that cares less about the television and more about playing with their learning games. Common assumption say that violent television shows can mold a child to be either violent when they get older or they develop a fear of being hurt. Children take what they see and apply it to what they do, kind of like the saying â€Å"Monkey see monkey do† type of thing. According to Willson (2008) â€Å"Wilson also shows that childrens susceptibility to media influence can vary according to their gender, their age, how realistic they perceive the media to be, and how much they identify with characters and people on the screen.† † (p. 87) Children need positive role models in their life and someone to look up to in life and most children have their television characters. Parents can usually see the signs in a child just by the way they are when watching a certain television show, and the way that they act if they cannot see the television show is a sign that a parent needs to watch the television show to see what it is that is addicting about the show to their ch ild to make them act out. There are many different types of signs to help parents know if the show that your child is watching is appropriate for them or if it is not appropriate for them. Some of the signs that parents want to look for is if they have trouble in school, with drawn away from friends and family just to name a few, and if you see these problems then as a parent should step in and try to pull the child/children away from the television shows that they watch. Some say that it cannot be done but studies have shown that if there is more quality time spent between parents and their child/children then they will more than likely not have the desire to watch television. Over the past 2 weeks I have been conducting my own personal study on how to keep your children from watching too much television and kept some notes on the effects it had on them. They are more a fan of watching different television shows and not wanting to even play with their toys. So one day I went to the store and bout some board games, activity books, coloring books, learning flash cards and even some reading books. What it is that I have found is that if I just took an hour of my time to interact with them to help get them started and interested in one of the activity’s that I have bought and got them started on one of them with me that I could leave them and do my school work, house work and even cook dinner and not one-time did I hear the words â€Å"I want to watch television Aunt Becca!† So if parents just make the time to take time out of your time just to get them interested is a tremendous outcome in the end. Obesity is one of the most dangerous side effects that are found in children that watch more television than get out and do physical activities. When children watch television after eating or while eating breakfast, snacks, lunches, and dinner are found that they don’t want to get up, stop watching television and go outside and play with friends or siblings. Now they are doing nothing to help burn off the calories that they are consuming then they run a risk at becoming obese and develop other health issues later in life. According to How T.V. Effects Your Child (1995-2012), â€Å"Studies have shown that decreasing the amount of TV kids watched led to less weight gain and lower body mass index (BMI — a measurement derived from someones weight and height)†. One of the things that can help children avoid becoming hungry while watching television is by trying to minimize the commercials, because commercials are filled with yummy foods and snacks that they like to eat. One of the things to help with that would be when there is a commercial on pull them away to do some sort of activity like, clean their room, fold cloths, or just by even having them come in and explain what it is that is going on in their television show. Monitoring what children watch on television is one of the best things that you can do to keep our children from becoming obese, violent, dependent on television, and less disruptive in school. In conclusion there are many different pros and cons of television and the effects that it has on children can go both ways, but it is up to the parents to make sure that their children get the physical activity, mental education and correct role models that they need to make sure that they live a more healthier and active life style. Because our children are the future of America and parents want to make sure that their future is going to be a bright and active life. Reference: PEDÃÅ"K, Dr. Åž. B. (2012, January).

Questions and Answers on DNA and MRNA

Questions and Answers on DNA and MRNA Rumana Anam Q1. What is the full forms of the following: D.N.A Deoxyribonucleic (The Free Dictionary, 2015) MRNA Messenger Ribonucleic Acid (The Free Dictionary, 2015) TRNA Transfer Ribonucleic Acid (The Free Dictionary, 2015) Q2. Complete the following sentences The synthesis of mRNA from DNA is known as:- Transcription (The Free Dictionary, 2015) The synthesis of proteins from RNA is known as:- Protein Synthesis (The Free Dictionary, 2015) Q3. Explain the process of Protein Synthesis detailing the role of DNA, mRNA, tRNA and ribosomes. The process where individual cells make protein is called protein synthesis. DNA and all RNA are both involved in this process. RNA are made by enzymes in the cell’s nucleus which start the process of protein synthesis by way of unwinding the wanted section of the DNA. A copy of one side of the DNA is formed by the RNA, and then is sent to all the other areas of the cell to help to bring altogether the different amino acids that make up proteins. As proteins are synthesised by mechanical and chemical processes within the cells, this process is called protein synthesis. Within the nucleus when the strand of RNA has been made, it is called messenger RNA MRNA. Through opening in the nucleus called pores the MRNA exits the nucleus and goes into the larger area of the cell which is called cytoplasm. As soon as the MRNA leaves the nucleus, it is attracted to a structure called ribosome, which are the cells work station or factory for protein synthesis. Within this point only one sub unit of ribosome is present. Another strand of RNA called transfer RNA, TRNA are activated as the MRNA start to attach to the ribosome sub unit. The TRNA stand finds the correct place to bind to the MRNA, as soon as it finds the place; it binds itself to the MRNA, which on one end holding amino acid. As this happens the other sub unit of ribosome come to completely form a complete structure. Another strand of TRNA appears as the ribosome encircles the strand of RNA. This strand is different from the first strand as it is carrying another amino acid; again the TRNA finds the correct place to bind to the MRNA. With the amino acid as soon as the second strand of TRNA is placed, both of the amino acid joins together aided by the ribosome, and adenosine triphosphate (ATP) with its cellular energy. As this pattern continues and repeats itself the chain of amino acid grows longer. As soon as all the amino acids have been placed in the correct sequence, a three-dimensional chain is made. O nce this has happened the protein is complete. When the proteins have been made the two sub-units of ribosome part to be joined later. In many ribosomes within the cell the process of protein synthesis take place there (Wisegeek, 2015). Q4.What is Point Mutation? Evaluate its effects. Point mutation is where there is a change within a gene, where one base pair in the DNA sequenced is changed or altered.Point mutation is most commonly the result of mistakes made during the DNA replication, however if DNA is exposed to x-rays and or ultraviolet radiations, this can also bring on point mutation. The two types of mutations are transition mutation and transversion mutation. Transition mutation happens when a pyrimidine base which is thymine (T) or cytosine (C) changes for another pyrimidine base, or it is when a purine base which is adenine (A) or guanine (G) changes for another purine base. Within a double stranded DNA each base is paired with a certain partner on the corresponding strand. A always pairs with T and C always pairs with G. For example a transition mutation is a GC base pair that swaps an AT base pair. However transversion mutation happens when a purine base changes for a pyrimidine base or the other way around i.e. when a TA or CG swaps for AT pair (Britannica, 2015). Point mutation can be put in three groups, nonsense mutation which is a code for a stop this can shorten the protein. Missense mutation which is a code for a different amino acid and silent mutation which is a code for the same or a different amino acid with no purposeful change in the protein itself. Missense mutation for example causes sickle cell disease, as the beta haemoglobin gene converts a GAG code into a GTG. This codes the amino acid valine instead of glutamic acid (Answers, 2015). The Effects of Point Mutation As all the cells within the body contain DNA therefore there are many places where point mutation can happen. However not all mutations are passed on to the offspring, these do not matter for evolution purposes. The mutations that matter for evolution purposes are those that can be passed on to the offspring, these happen in the reproductive cells eggs and sperm this type of mutation is called germ line mutation. There are three effects of germ line mutation:- No change happens in the phenotype, this is where there is no effect on the organism. This can happen in a part of the DNA strand where there is no function, or it can happen in a protein coding area but does not affect the amino acid sequence of the protein. Small changes happen in the phenotype, a single mutation can cause some cats ears to curl backwards. Significant changes happen in phenotype, this is where significant changes happen within the organism for example sickle cell disease. A single mutation can cause negative effects for the organism for example mutation that cause death, this is called lethal. Mutations are sometimes stereotyped as unimportant or the cause of genetic disease. While many mutations do have a negative effect, other mutations can have a small positive effect. Mutations that control genes can have a huge and sometimes positive effect. As some areas of the DNA control other genes, that decide when and where other genes are turned on, mutation in these parts can considerably change the way an organism is built. This can cause flow of effects in the behaviour of the genes under its control. Organisms have control genes that shape how the body is laid out i.e. the Hox gene is found in humans and animals. This gene sets out where the head goes and where limbs grow. These control gene build the bodies units i.e. limbs, head etc, therefore evolving a huge change in basic body lay out can be likely by a change in the Hox gene and natural selection (Understanding Evolution, 2015). Task 2 Q5. What is the probability of a couple having a boy or a girl? Male X Y Female X X XX = Girl XY= Boy The probability of a couple having a boy is 50%, the probability of a couple having a girl is 50%. Q6 What chromosomal abnormalities occur in the inheritance of Down’s syndrome Down syndrome is a result from trisomy 21, this is where the 21st chromosome has three chromosome and not the normal 2 chromosome. Therefore the individual will have 47 chromosomes and not the normal 46 chromosome. Down syndrome is cause by chromosomal abnormalities that happens randomly in the development stage of reproductive cells within a parent. This normally happens in the egg, but can sometimes happen in the sperm. The mistake in cell division results in a reproductive cell with abnormal number of chromosome, trisomy 21. This condition brings on intellectual disability, a characteristic facial appearance and weak muscle tone, all individual that are effected have cognitive delay (Genetics Home Reference, 2012). Q7. Explain inheritance of a sex-linked condition with a relevant example Hemophilia A and hemophilia B are both inherited sex linked traits, where they are inherited through the X linked recessive pattern. The genes that cause this condition are in the X chromosome, which is one half of the two sex chromosomes, the other being the Y chromosome. As males only have one X chromosome, one changed copy of the gene in the cell is enough to cause this condition. As females have two X chromosomes a mutation would have to have happened in both of the copies of the genes to cause this condition. This is very rare to happen in females as both copies of genes would have to have the same mutation happened to them. Therefore it is rare for females to have hemophilia. Fathers cannot pass on the inherited X linked condition to their sons as this is one of the characteristics of X linked inheritance. Females who have this X linked recessive condition have one mutated gene are called carriers. Female’s carriers have normally half the amount of coagulation factor whi ch is enough for blood clotting. Some female’s carriers have less than half of the normal amount of coagulation factor, these carriers are at risk for abnormal bleeding (About Education, 2015). Q8. Explain the inheritance of either cystic fibrosis or phenylketonuria Cystic fibrosis is a disorder that causes respiratory failure and vitamin deficiencies. Cystic fibrosis effects the secretion of the body i.e. saliva, mucus, sweat and digestive juices. As this secretion should be thin and watery, they are thick and sticky. This causes passageways to be clogged up within the body which causes damage to the pancreas and lungs. Cystic fibrosis is caused by inheriting defected gene from both parents, known as recessive gene. Cystic fibrous cannot be inherited by the off spring, if only one parent has the gene. If the off spring has only one defective gene then they are carriers of cystic fibrosis, this means that they will have the potential to pass on the defective gene to their off spring (eHow, 2015). The off spring labelled Ff are carriers, they have one defective gene but do not have the disorder themselves. In the diagram above both parents are carriers, they have one in four chances of producing an off spring that has cystic fibrosis (Bitesize, 2014). In the diagram above one parent is a carrier, while the other is not. They will not produce an off spring with cystic fibrosis, but are able to produce off springs that are carriers (Bitesize, 2014). Q9 Describe the process of genetic screening explaining the application of DNA recombinant technology in the treatment of a named medical condition.   Genetic testing is a medical test that can indicate any changes in the chromosomes, genes and proteins. The result of genetic testing can help to confirm or reject an alleged genetic condition, disease that the individual may have suspicion of, or help verify their chances of developing and or passing on a genetic disorder to their off spring. Some of the methods of genetic testing can be of these. Molecular genetic testing, this is where the medics study a single gene or short lengths of DNA to find defectiveness or mutation that may lead to a genetic disorder. Chromosomal genetic testing, this is where a whole chromosome and or long lengths of DNA to see if there are any sizable genetic changes i.e. extra copy of chromosome. Biochemical genetic testing, this is where the activity level or the amount of proteins are studied; any abnormalities that are detected can indicate genetic disorder (Genetic Home Reference, 2015). DNA recombinant technology, is a technology that produces DNA artificially. The DNA in living organism has been changed today due to this procedure. This procedure involves taking DNA from two difference sources and merging it together for it to become one single molecule. However this only works when the artificially created DNA has been reproduced, this is known as DNA cloning. The two types of cloning that DNA recombinant technology is used for are, therapeutic cloning and reproductive cloning. The reproductive cloning produces an organism with the exact same genetic information from the one that already is living. This type of cloning has been done with Dolly the sheep. Dolly was the first mammal to be reproduced as a genetic copy. Therapeutic cloning, reproduces tissues and or organ and not the whole organism. Therapeutic cloning has a great deal of benefit, i.e. if an organ has cancer it can be replaced with one made from the individuals own DNA. This reduces any likely hood of organ rejection within the body when a tissue or organ transplant is preformed (Wisegeek, 2015). Q10 Discuss the moral and ethical issues raised by DNA recombinant technology Not everyone is in favour of DNA recombinant technology, as they feel that science is playing god by reproducing unnaturally organisms that are not meant to be. And that science is devaluing the uniqueness of life itself. Also that some DNA work involves destroying embryos, this angers some social activist as this death is bought on intently this could be classed as murder. However scientist, argue that the purpose of DNA recombinant technology is to benefit and save human life, and not to destroy it (Wisegeek, 2015).

We Must Regain Our Lost Civil Liberties Essay -- Privacy Act, Patriot

With our nation’s tragedy of September 11, 2001, arose a deeply shaken America, shocked by the extent of the cruelty. An act of terrorism of that magnitude had never been seen before in our country. Patriots quickly came together, supporting the president to pass legislation, known as the USA Patriot Act, to tackle internal and external threats to this nation. The debate ensued, focused on which types of surveillance technology should or shouldn't be allowed for arresting terrorists. However, the question remains as to how these devices are going to be used, and how personally are those who use them held accountable. The purpose of this paper is to confirm that the proposed monitoring and archiving of users’ information on social networking sites would represent yet another erosion of our civil liberties for only a minor gain to our national security. The USA Patriot Act or simply the Patriot Act sanctions the use of wiretaps, additional surveillance of technology, such as voice mail and e-mail, trap and trace devices, and demands for educational and business records. The Department of Justice justifies that such actions in criminal investigations, have been used for years. However, this action comes under intense scrutiny by critics such as the ACLU who maintain that the secrecy surrounding the use of such tools as well as lower criteria for attaining the authority to use them â€Å"represents a broad expansion of power without building in a necessary privacy protection† (The USA PATRIOT Act: Myth vs. Reality, n.d.). The Patriot Act was signed into law on October 26, 2001, 45 days after the terrorist attacks on September 11th.

The Complex Character of Iago of Shakespeares Othello Essay -- Othell

The Complex Character of Iago of Othello      Ã‚   Iago can be clearly characterized as the villain in Shakespeare’s Othello.   The notion of the "honest" Iago does at times appear not to be a misnomer.   In this essay I shall attempt to explore the complexities contained within the character of Iago.    One of the most interesting questions that crops up is the one concerning Iago’s motives. What are his reasons to kill every major Venetian in Cyprus? Shakespeare seemingly sets the stage for Iago’s actions, giving him two distinct reasons to avenge Othello. The first is the fact that Othello promotes Cassio, an "arithmetician" to the rank of lieutenant and passes over Iago who is but a sergeant. Secondly, Iago is suspicious of his wife, Emilia and thinks she is sleeping with every other man but him—including Othello. There are other reasons that Iago talks about in his soliloquies—the primary one being jealousy or "the green-eyed monster." Iago resents the love that Othello and Desdemona share and also takes offence at the fact that Othello is older, yet he has a young and beautiful wife, power, and respect, all that Iago desires. However, all these reasons seem to be false and made-up just for the sake of being excuses for his malice or perhaps they seem to sum up a sense of paranoia. Furthermore he uses these reasons to convince Roderigo to hate Othello. The real motive seems but a slip on Iago’s part w... ... Works Cited and Consulted Bradley, A. C.. Shakespearean Tragedy.

Iliad :: essays papers

Iliad Achilles’ Anger and Unreconciliation: Reassessing the Concepts of Mortality and Honor The subject of Homer’s epic poem, the Iliad, is very clearly stated--it is â€Å"the rage of Peleus’ son Achilles.† The reader remains continually aware of the extent of Achilles’ rage, yet is never told the reason why Achilles remains angry and unreconciled. There is no definitive answer to this question. Achilles is not a static character. He is constantly changing; thus the question of why he remains angry solicits different answers at various stages throughout the poem. To find an answer, the reader must carefully examine Achilles’ ever-changing dilemma involving the concepts of mortality and honor. At its simplest, Achilles’ dilemma is that if he goes to war, he will die. But he will die with glory. Achilles’ true nature is that of a warrior. The son of Peleus must fight. When he denounces Agamemnon and the Achaeans, he does not go home. His ship is last in line, near Troy. Subconsciously, he has already made the choice of accepting a short life filled with glory. Subconsciously, he wants to go back to war. He needs to. However, he also needs to insure his possession of glory and honor. But what kind of glory, what kind of honor? He already possesses the honor of the gods. He says, â€Å"my honor lies in the great decree of Zeus†¦Ã¢â‚¬  (IX.741.p.272). By book IX, material wealth is no longer what Achilles wants. He spurns Agamemnon’s offers. The typical mortal concepts of heroism no longer concern him; his ideals differ from those of his peers. Phoenix’s Meleager is no example to him. However, at this point Achilles still does not know what he wants. Pride and stubbornness still supplement his rage, but now his anger appears to be a manifest ation of his fear and confusion—â€Å"Stop confusing my fixed resolve with this†¦Ã¢â‚¬  (IX.745-746.p.272). Achilles knows that he wants honor and glory, but in what form? What Achilles does know, and what he must deal with, is the fact that his life will be short if he chooses to have honor and glory. Thus, the choices he makes concerning his honor are crucial. At this point his life is riding on the decision he makes. It is inevitable that Achilles will choose door #2--to go to war, live a short life, and have much glory.

Erikson’s Theories Personal Portrait Essay

Erik Erikson’s and Lawrence Kohlberg developed several different theories that demonstrated each phase of our lives. Their theories demonstrated how each stage developed and how the stages help to make us who we are today. We develop, learn, and revolutionize through developmental and moral developments. This paper will illustrate how each developmental and moral development represents each stage of life. Erik Erikson’s stages of developmental theory consist of eight stages of development versus Lawrence Kohlberg’s six stages of moral developmental theory. Both of these theorists beliefs were different when it came to the breakdown of each stage. Erikson’s infant stage which consisted of trust vs. mistrust which is â€Å"the need for maximum comfort with minimal uncertainty to trust himself/herself, others, and the environment( Patient Teaching, 1990).† This is a stage that I cannot relate to because I do not have any memories from infancy. Kohlberg’s first stage is â€Å"obedience and punishment† which relates that a â€Å"child assumes that powerful authorities hand down a fixed set of rules which he or she must unquestioningly obey (Kohlberg, 1958b). For example, your principle in your elementary school down to your teacher is an authority figure. I relate to Kohlberg’s stage because I can remember growing up and knew that my parents, teachers, and principles were my authority figures. I knew that I must obey them and if I did not that it would result in severe punishments and sometimes multiple punishments from each individual. Being a female, a felt that I feared authority figures more than my brothers or other boys in my class. Second stage of Erickson’s was the â€Å"toddler† stage â€Å"autonomy vs shame and doubt-works to master physical environment while maintaining self esteem â€Å"The second stage occurs between 18 months and 3 years. At this point, the child has an opportunity to build self-esteem and autonomy as he or she learns new skills and right from wrong. The well-cared for child is sure of himself, carrying him or herself with pride rather than shame. During this time of the â€Å"terrible twos†, defiance, temper tantrums, and stubbornness can also appear. Children tend to be vulnerable during this stage, sometimes feeling shame and low self-esteem during an inability to learn certain skills (Erikson, 1968).† Kolberg’s second stage â€Å"Individualism and Exchange† â€Å"At this stage children recognize that there is not just one right view that is handed down by the authorities. Different individuals have different viewpoints (Kohlberg, 1963, p. 24).† Both Erikson’s and Kohlberg’s theory can be a demonstrated at an early childhood stage. One learned that they were an individual and that one had to respect authority figures. I can remember a time that I was in preschool and I was asked why I took another child’s crayon. I remember stating to the teacher that I wanted my crayons to remain new. I was already developing a sense of being selfish and using others. That was not the route to take which was expressed to me by both my teacher and my parents. The third stage is â€Å"Initiative vs. Guilt† which demonstrates â€Å"purpose† â€Å"During this period we experience a desire to copy the adults around us and take initiative in creating play situations. We make up stories with Barbie’s and Ken’s, toy phones and miniature cars, playing out roles in a trial universe, experimenting with the blueprint for what we believe it means to be an adult. We also begin to use that wonderful word for exploring the world—†WHY?†(Erikson, 1968)† Whereas Kolhberg’s stage result in â€Å"good interpersonal relationships† At this stage children–who are by now usually entering their teens–see morality as more than simple deals. They believe that people should live up to the expectations of the family and community and behave in â€Å"good† ways. Good behavior means having good motives and interpersonal feelings such as love, empathy, trust, and concern for others. Heinz, they typically argue, was right to steal the drug because â€Å"He was a good man for wanting to save her,† and â€Å"His intentions were good, that of saving the life of someone he loves.† Even if Heinz doesn’t love his wife, these subjects often say, he should steal the drug because â€Å"I don’t think any husband should sit back and watch his wife die† (Gibbs et al., 1983, pp. 36-42; Kohlberg, 1958b). These two stages are somewhat different in comparison. Erikson’s theory is basically demonstrates how a child mimics what he or she see by using inanimate objects. I believed every little girl played house with Barbie and little boys played cowboys and Indians. I loved to play in my doll house at the age of 4 and older. I also was starting to demonstrate what was right or wrong. Erikson’s fourth stage â€Å"School-Age Child (Competence) – Industry vs. Inferiority† â€Å"the Latency, we are capable of learning, creating and accomplishing numerous new skills and knowledge, thus developing a sense of industry (Erikson, 1968).† Kohlberg fourth stage is â€Å"Maintaining the Social Order reasoning works best in two-per son relationships with family members or close friends, where one can make a real effort to get to know the other’s feelings and needs and try to help (Crain, 1985, p 124).† These two stages exemplify several social skills. There are alike in detail. The age range from 6 to 12 is a very adequate age. I can recall being in the 4th and 5th grade and starting to have friends. I was a cheerleader and was learning that you have to be social in order to develop friendships. I was also taught by parents that little boys teased and picked on me because they liked you. I did not understand this but as I got older I slowly started to understand the concept of relationships. Next, the fifth stage of Erikson is â€Å"Identity vs. Role Confusion – Fidelity† â€Å". At this point, development now depends primarily upon what a person does. An adolescent must struggle to discover and find his or her own identity, while negotiating and struggling with social interactions and â€Å"fitting in†, and developing a sense of morality and right from wrong (Erikson, 1968)† Thus, Kohlberg’s fifth stage is â€Å"social contract and individual rights respondents basically believe that a good society is best conceived as a social contract into which people freely enter to work toward the benefit of all. They recognize that different social groups within a society will have different values, but they believe that all rational people would agree on two points. First they would all want certain basic rights, such as liberty and life, to be protected (Crain, 1985, p.125).† I feel that both of these stages are very similar. We want society to help us while giving back to society. It shows a sense of being part of something big. For example, I like the fact that I am able to vote. I believe that voting is a huge part of being part of society. It is important to know and feel that importance. The sixth stage of Erikson is â€Å"Intimacy and Solidarity vs. Isolation – Love† â€Å"the age is from 18-35, at the young adult stage, people tend to seek companions hip and love. Some also begin to â€Å"settle down† and start families, although seems to have been pushed back farther in recent years (Erikson, 1968).† Final stage of Kolhberg is â€Å"universal principles which believes that there must be a higher stage–stage 6–which defines the principles by which we achieve justice (Crain, 1985, p132).† These two stages are very different. Erikson is speaking about finding love which is considered your soul mate. Ages 18 through 35 is the common age that people start settling down and having children. I was 21 when I gave birth to my daughter. I tried to stay with her father which was 7 years older than me. He had not matured and did not want to step up to his responsibilities, even though he was much older than me. Kohlberg felt that stage 6 which resulted in the final decision of respecting each other’s beliefs. I find myself using an open mind and not judging anyone for their differences. I can relate to both of these stages. Erikson’s last two stages are â€Å"Middle-aged Adult: age ranges from 35 to 55 or 65 and the stage is Generativity vs. Self absorption or Stagnation which is defined as Care â€Å"Career and work are the most important things at this stage, along with family. Middle adulthood is also the time when people can take on greater responsibilities and control (Erikson, 1968).† Next, â€Å"Late Adult: age ranges from 55 or 65 to Death and the stage Integrity vs. Despair defined as wisdom As older adults, some can look back with a feeling of integrity — that is, contentment and fulfillment, having led a meaningful life and valuable contribution to society. Others may have a sense of despair during this stage, reflecting upon their experiences and failures( Erikson, 1968).† I am not at either stage of my life. I am very close to middle age. I actually consider myself to be a middle aged adult now. I am focused on furthering my career and supporting my family. I feel that this stage should be very important to both males and females. I have learned from working in the criminal justice field that this stage is not very important to males in society. There are more men in prison and jail than there are females. These men do not put the proper priorities in order to stay stable and have legitimate career. I am destine to reach far beyond 65 and live my life prosperous. In Closing, these two theorists had the same theories in mind. They described each stage of development differently. There concepts both compared and contrast with each other’s stages. I related to both theorists. I consider my life as a mirror of both Erikson’s and Kohlberg’s stages. Their phases exemplify positive and refined steps of everyone’s life. References Crain, W.C.
