Essay on American Pie. Coercive Sexuality - 693 Words

Coercive Sexuality By Diep Chu FS 337 March 2013 Coercive Sexuality Coercive sexuality is an important factor in American Pie movie. In this movie, audiences can see different pictures of teenagers trying to experiences sexual intercourse for the first time in their lives (Zide, Perry, and Weitz, 1999). And the more aggressive they are, people can see coercive sexuality involved in different scenes. Coercive sexual behavior among students has been an area of concern to society. At the time when human sexuality topic becomes so popular in teenagers’ world, those students in the movies let people understand more about their points of views about sexuality. The question that I want to address in this paper is: Do we as a†¦show more content†¦But on her side, she sure will not be happy to have him do that without her consent (Zide, Perry, and Weitz, 1999). In what way do the attitudes towards these mirrors the attitudes of our society in general? For many years society tried to control sexual behavior in youth by citin g the traditional negative consequences of sexual experiences and community disapproval. Television, being the highly influential, has been both part of the solution and part of the problem in the area of sex and youth. At the beginning, Jim was watching porn and his parents notice it (Zide, Perry, and Weitz, 1999). This would happen to many families in our society today when kids are in puberty. Those entertainments affect teen’s sexual behavior heavily. They will copy those disapproval contents in it. At almost the end of the movie, those youth figured out they want to experience sex only because of peer pressure. They finally understand sex had no meaning without love or the girls’ willingness (Zide, Perry, and Weitz, 1999). Public education has had some major problems in this area and few schools have any real programs in sex education. Many parents do not want their children to learn about sex early. But the more they avoid it, the more kids want to learn about it . This movie indicates good pictures of how teens nowadays think about sex. The sexual values are much different in themShow MoreRelatedLeading Function of Management15642 Words   |  63 Pages16 ORGANIZATION AND MANAGEMENT – Report on The LEADING Function of Management 7) Contributions of Elton Mayo : The work of Elton Mayo is famously known as â€Å"Hawthorne Experiments.† He conducted behavioral experiments at the Hawthorne Works of the American Western Electric Company in Chicago.

The Equilibrium Constant of an Ester Hydrolysis Reaction Abstract: The results from this experiment show four different Kc equilibrium constants of: . 1522 for bottle two, . 1853 for bottle three, . We will write a custom essay sample on Ester Hydrolysis or any similar topic only for you Order Now 2094 for bottle four, and . 2678 for bottle five. The average Kc value came out to be . 2037 for all four bottles. Purpose: The purpose of this lab is to determine the equilibrium concentrations of an organic acid, an alcohol, an ester, and water in four bottles with varying measurements of each compound in of the four solutions. Once the concentrations are determined, one is then to discover the Kc, equilibrium constant, of those solutions by dividing the concentrations of alcohol and acid by the concentrations of ester and water. Methods/Procedure: First begin by mixing up and standardizing a 500mL solution of NaOH to titrate. For each of the six bottles, measure the directed amounts of ester, water, alcohol, and HCl. The bottles of different solutions will be left to come to equilibrium for two weeks. Once the NaOH is standardized, the solutions in the bottles have come to equilibrium, and a molarity is calculated, use the molarity of NaOH to discover how many mols were used to neutralize the solutions in each bottle. Once all of the calculations are complete, use an ICE chart to discover the mols of ester, water, acid, and alcohol at equilibrium to then calculate the Kc for each bottle. After a Kc has been calculated for all bottles, the last step is to determine an average Kc for all of the solutions.

The mass was below 5 grams (4. 8778g) which threw the calculations off. To compensate for the poor data, an average of the two masses of hydrochloric acid was taken, and then the number of moles was found to get a better approximation of what the number of moles should be. Another possible error in this experiment was not having adequate time for the solutions to equilibrium completely. If the solutions had not fully reached equilibrium the equilibrium constant would be off for whichever solutions, if not all, that had not come to equilibrium. The Kc values were all approximately one tenth off of each other. In theory, the Kc values should all be the same which indicates that there is a high probability that the solutions had not fully reached equilibrium. In conclusion, the results would have been closer and more exact had the solutions had more time to come to equilibrium as well as if the mass of hydrochloric acid was closer to where it should have been.

Tennis Essay Example For Students

Tennis Essay It was my last year at San Fernando high. It was a memorable time of my lifebecause I knew that I would graduate at the end of that year. My senior yearalso became the most significant year of my life, because I got to do somethingthat I have always wanted to try tennis. I had always wanted to play tennis eversince I was a kid, but there wasnt enough time for me to join tennis team. Oneday, Mr. Cockerill who was my teacher and also the tennis coach, encouraged meto join the team. I thought it might be the only chance for me to get involved,and decided to join the team. Mr. Cockerill was assigned to be our coach. He isa tall, strong old man with a red face. I loved to listen of what he said,because I felt he was giving me a valuable lesson especially during practicehours that he thought it could be use for the game. My first lesson was not thatgreat. I had to pick up the balls most of the time. I was unable to hold firmlya tennis rackets grip. I practiced very hard almost every day af ter schoolincluded the weekends. There were few times I wanted to quit the challenges, butmy friends had given back my courage. These friends of mine had started playingtennis two years before I came in to join the team. Their skills were so muchimproved compared to me. They were willing to stay and practice with me. I wasalso happy that my oldest brother, an excellent singles player helped me out atthe start. At home I often admire his awards and whispered to myself that;I would never get one like this all my life. It is impossible for me to bean athlete. In the beginning, I knew that I wasnt a good player, but itdidnt stop me from joining the team. However my father was worried that if Icame home so late at night, I wouldnt have enough time to study for otherclasses. He didnt allow me to be involved in this kind of activity. I wanted tobeg my dad to let me continue, but we didnt have a good communication with eachother. I felt either very guilty for not joining the team or for goi ng againstmy dads will. He would disown me if I didnt listen to him. I felt I was pushedto the edge of a cliff. His attitude had emotionally hurt when I personallyheard it of what he had treated me. I couldnt stop crying for days. My tearsjust ceaselessly drooped. My coach worried why I didnt look so well in class. We will write a custom essay on Tennis specifically for you for only $16.38 $13.9/page Order now He asked few times, but I couldnt find a way to start explaining the wholesituation. I really wanted to resolve this problem as soon as possible. It wasmy dream to be in tennis team, and Mr. Cockerill was the only person who cantalk to my dad. Finally, he actually did let me join the team. In the end, Irealized that how difficult it was for me to be on the tennis team. I shouldplay my best in order to please my dad, my coach, my friends, and for SanFernando high. During the first tournament, I was very nervous and excited atthe same time. It was my first competition; I couldnt hold my racket still. Myentire body was shaking, but luckily no one noticed that. Mr. Cockerill gatheredus in class and explained what the strategies would be and how we should play. He also reminded us to have a positive attitude even if we lost the game. At theend of the game I lost to my opponent with a scoring 3-8. I felt very happy thatat least I had made some effort for my score, and I took me few weeks topractice. Mr. Cockerill was very kind and so understanding. He didnt only slowanything about the lost, but he also took well care of us with cookies, fruitsand drinks. I had followed his teaching, as long as you all do your best,I am very please, and I ask no more than that. I kept it as anencouragement. My time was devoted to this game at least one or two hourseveryday. Mr. Cockerill was very satisfied because I would never complain aboutthe practice section and I always gave smile at him. I practically never won thegame myself, although I had learned to improve my skill from those experts whohad been playing for years. I didnt feel that bad because it took me a fewmonths to be Varsity. I didnt win any game, but I could tell myself each time Ihad to play that, I have done my best. Once, during a game, Itwisted my ankle when I served the ball. I said nothing to my coach, because Iwas afraid to let him down nor I wanted him to be worried. They didnt realizehow hurt I was at that day. I had to pretend to smile at my team. I was veryqueer; I had to endure that physically pain till the last second. It took me fewdays to recover my ankle. That was also the last game that I played for SanFernando high. The last day of a semester, Mr. Cockerill invited all of membersin the team to the banquet. There most of my team members had received theiraward letters and trophies. At last, the final trophy was given as aninspiration to Kim-Anh Le, he yelled out loud. It is forme? I was so surprise and looked around the room to see if he was kiddingme. I was speechless at that moment. As I walked up to the stage to receive theaward, I heard all the clapping hands toward me. Mr.Cockerill gave me a hug andwhisper in my ear, you deserve it, honey. I am very proud of you.This beautiful day has always been there ever since I graduated. It was such abest memory that I had treasured in my heart. It couldnt describe how myfeeling was at the banquet, but Mr. Cockerill had adhered to my mind, he wasalways there for me to look up to. All I really wanted to say is thanks toMr. Cockerill for giving me a best lesson that I have ever had. Now I haveable to play tennis without any help. .uac2f96291216f0fb9ec7c4c35031cde7 , .uac2f96291216f0fb9ec7c4c35031cde7 .postImageUrl , .uac2f96291216f0fb9ec7c4c35031cde7 .centered-text-area { min-height: 80px; position: relative; } .uac2f96291216f0fb9ec7c4c35031cde7 , .uac2f96291216f0fb9ec7c4c35031cde7:hover , .uac2f96291216f0fb9ec7c4c35031cde7:visited , .uac2f96291216f0fb9ec7c4c35031cde7:active { border:0!important; } .uac2f96291216f0fb9ec7c4c35031cde7 .clearfix:after { content: ""; display: table; clear: both; } .uac2f96291216f0fb9ec7c4c35031cde7 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uac2f96291216f0fb9ec7c4c35031cde7:active , .uac2f96291216f0fb9ec7c4c35031cde7:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uac2f96291216f0fb9ec7c4c35031cde7 .centered-text-area { width: 100%; position: relative ; } .uac2f96291216f0fb9ec7c4c35031cde7 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uac2f96291216f0fb9ec7c4c35031cde7 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uac2f96291216f0fb9ec7c4c35031cde7 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uac2f96291216f0fb9ec7c4c35031cde7:hover .ctaButton { background-color: #34495E!important; } .uac2f96291216f0fb9ec7c4c35031cde7 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uac2f96291216f0fb9ec7c4c35031cde7 .uac2f96291216f0fb9ec7c4c35031cde7-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uac2f96291216f0fb9ec7c4c35031cde7:after { content: ""; display: block; clear: both; } READ: The Dangers Of Cyber Bullying EssaySports and Games

The amount of HCl and distilled water used always equals 50cm3 in total as it did in the demonstration. I have chosen o choose eleven different co ...

Rules for Assigning Oxidation Numbers

Rules for Assigning Oxidation Numbers Electrochemical reactions involve the transfer of electrons. Mass and charge are conserved when balancing these reactions, but you need to know which atoms are oxidized and which atoms are reduced during the reaction. Oxidation numbers are used to keep track of how many electrons are lost or gained by each atom. These oxidation numbers are assigned using the following rules. Rules for Assigning Oxidation Numbers The convention is that the cation is written first in a formula, followed by the anion. For example, in NaH, the H is H-; in HCl, the H is H.The oxidation number of a free element is always 0.  The atoms in He and N2, for example, have oxidation numbers of 0.The oxidation number of a monatomic ion equals the charge of the ion.  For example, the oxidation number of Na is 1; the oxidation number of N3- is -3.The usual oxidation number of hydrogen is 1.  The oxidation number of hydrogen is -1 in compounds containing elements that are less ​electronegative than hydrogen, as in CaH2.The oxidation number of oxygen in compounds is usually -2.  Exceptions include OF2 because F is more electronegative than O, and BaO2, due to the structure of the peroxide ion, which is [O-O]2-.The oxidation number of a Group IA element in a compound is 1.The oxidation number of a Group IIA element in a compound is 2.The oxidation number of a Group VIIA element in a compound is -1, except when t hat element is combined with one having a higher electronegativity.  The oxidation number of Cl is -1 in HCl, but the oxidation number of Cl is 1 in HOCl. The sum of the oxidation numbers of all of the atoms in a neutral compound is 0.The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.  For example, the sum of the oxidation numbers for SO42- is -2.

Physiology Essay Example | Topics and Well Written Essays - 1000 words

Physiology - Essay Example While osteoblasts are bone-forming cells, osteocytes are mature bone cells and osteoclasts break down and reabsorb bone (†Bone Growth and Development†). Ossification is basically of 2 types, intramembranous and endochondral. In both these, the formation of bone tissue is similar. First, there is increase in the number of cells and collagen fibers. Then, the cells differentiate into osteoblasts. These cells form an organic matrix called the osteoid in which the bone salts are deposited. Some of these osteoblasts remain in the matrix and transform into osteocytes (Gardner, 856-862). The replacement of sheet-like connective tissue membranes with bony tissue is known as intramembranous ossification and bones formed by this method are known as intramembranous bones. Some of the flat bones of the skull and irregular bones fall into this category. These bones are initially formed as connective tissues membranes, later on the osteoblasts migrate to the membranes and deposit bony matrix around themselves and change into osteocytes. Replacement of hyaline cartilage with bony tissue is known as endochondral ossification. Most of the bones in our body are formed in this manner and hence these bones are known as endochondral bones. The bones are first formed as hyaline cartilage models as early as in the 3rd month of gestation. This is surrounded by a membrane called the perichondrium. Later, this becomes infiltrated with blood vessels and osteoblasts and then is called the periosteum (†Bone Growth and Development†). Primary center of ossification is the region in the bone in which the process of ossification starts first and this is indicated by an increase in the cells and fibers. Ossification continues from this center toward the ends of the bones. The time at which the primary center appears depends on the bone. The parietal and frontal bones, maxilla, and mandible appear during the embryonic period. In the long bones, the primary center of ossification

COMPARE THE RIGHTS AND RESPONSIBILITIES OF A UK ADULT CITIZEN AND A Essay

COMPARE THE RIGHTS AND RESPONSIBILITIES OF A UK ADULT CITIZEN AND A REFUGEE OR ASYLUM SEEKER BOTH LIVING IN THE UNITED KINGDOM IN TERMS OF HEALTH AND SOCIAL SECURITY - Essay Example This essay compares the rights and responsibilities of Asylum seekers and adult U.K citizens in terms of health and social security. The United Kingdom adult citizens exercise their rights and responsibility of contributing to the issues of health and social securities by voting and raising public opinions to the government. In contrast, the contribution of asylum seekers in these issues is minimal due to language barriers. The government tries to involve them by providing them with channels to communicate and give their decisions regarding the issues affecting them (NRIF, 2006: CRC, 2004). For instance, the ‘English for Speaker of other Languages’ program aimed at teaching English to this group of people (ISE, 2005: Ragu, 2008). This effort aims at improving their communication abilities so that they can be able to take up their rights and responsibilities. All adult citizens of U.K. have an absolute right to the National Hospital Services (NHS), which includes free medical treatment and care. On the other hand, not all Refugees and Asylum seekers receive this facility (Aspinall & Watters, 2010, p.23). Those asylum seekers who have not received permanent residence confirmation from the government cannot access this facility. They have access to the medical services but at their own cost (Palmer & Ward, 2007). Those who have received confirmation enjoy national health services (NHS) without any payment (Crawley & Crimes, 2009). All adult citizens in U.K. have the right to register with a general practitioner of their choice free of charge. If a general practitioner cannot register them, he or she should give a substantial reason in writing to explain the cause (CIC, 2007). Contrary, refugees and asylum seekers may apply with general practitioners (Lee, 2006: Refugee Council, 2005). However, the general practitioners have the right to consider such applications and decide whether to accept them or
