The Psychology of Groups Essay Example for Free

The Psychology of Groups Essay In life, people have groups that they use to compare themselves to. These groups, or reference groups, serve as benchmarks that we can compare our lives to. College students in particular have a large array of these groups because their lives are at a point where they are being shaped the most. College students are on the cusp of careers, families, and they are shaping who they want to be in the future. Parents make an excellent reference group for college students because they generally have well established careers and families. Kids grow up modeling their behavior after their parents, so it is natural that they would use their parents as a reference group throughout their lives. Parents are important reference groups because the person referencing them has close emotional ties with them, and are a benchmark for success at home, and in careers. Coworkers are another important reference group as well. Coworkers are often times people well established in careers, and can serve as a good benchmark for success at work. We can use coworkers to compare how we are doing in our field of work in regard to doing the work, getting promotions, and balancing work and home life. I think the most important reference group that college students have are other college students. College is a competitive place, since the people with the highest grades get the best rank in each class. Referencing your peers is a good way to judge your progress in college, and can make you more competitive in college and later in life. In conclusion, the most important reference groups that a college student can have are parents, coworkers, and other college students. These groups serve as benchmarks for making progress in our lives, can make us more competitive, and show us how we can make ourselves better.

B737 Ng Flight Control System Engineering Essay

B737 Ng Flight Control System Engineering Essay In this chapter the differences of the Airbus A320 and Boeing 737 NG will be discussed. There will be looked at the flight control system of the Boeing 737 NG and the flight control system of the Airbus A320 (2.2) after that a comparison between the conventional system and fly-by-wire system (2.3). 2.1 B737 NG flight control system This section will discuss the flight controls of the Boeing 737 NG. At first the primary flight controls especially the ailerons (2.1.1) and also the secondary flight controls of the Boeing 737 NG trailing edge devices (2.1.2) will be discussed. 2.1.1 Primary flight controls In this subsection, the primary flight controls of the Boeing 737NG will be discussed. The ailerons will be investigated as primary flight control in this chapter. The composition of the system (2.1.2a), the input of the system (2.1.2b), the transportation of signals (2.1.2c), the output signals (2.1.2d) and the hydraulic system of the Boeing 737NG will be discussed (2.1.2e) 2.1.1a Composition The aileron system exist of two ailerons. The Boeing 737 has an aileron on each wing. They are placed on the outer side of the wing to create a greater moment over the airplanes longitudinal axis. Over this axis the airplane will be able to roll. Because the ailerons are mounted on the outer side of the wing the needed forces can be lower than when they are placed on the inner side of the wing. The moment of the aileron is the force multiplied by the arm length. 2.1.1b Input The ailerons are positioned by the control wheels of the pilots. When the pilot controls his steering wheel a mechanical cardanic movement will make the input signal transferred to the transfer mechanism.The transferm mechanism keep the control wheel movement to a limit of 107.5 degrees left and right. This mechanism is mounted under the steering column of the pilot. The roll axis force transducer is mounted between the control shaft and aileron drum below the captains control column. The force transducer provides dual electrically isolated ac output signals that are proportional to the force applied to the control wheel or column. The signals are used by the autopilot computers when the system is engaged in CWS (manual) mode or in CMD mode with no flight mode selected. Both control wheels are cable mounted connected to each other, when the captain steer his control wheel the left aileron control bus drum will rotate and operated the control cable to rotate the right aileron control bus drum. This drum is connected exactly as the captains control wheel and the first officers control wheel will move. C:UsersTemminckDropboxHvA Projectgroep 1VProjectWerkmapKeespage 27-4.jpg 2.1.1c Transport By rotating the control bus drum, the control drum also will rotate. The control cable will be operated and will run through the airplane and routed by cable guides and kept on tension with cable tensioners. In the main wheel well the cable will be attached to the aileron body quadrant. On the quadrant the new outgoing cable is mounted. The quadrant is mounted on two aileron power control units (PCU). This PCUs are mounted at the aileron control quadrant. On this quadrant the aileron input shaft is mounted. On this shaft the autopilot control rod, the PCUs four pogo input cranks, the feel and centering unit and the aileron actuator are mounted. For backup two PCUs are mounted to help the pilot to create a higher force to the ailerons so the pilot dont need all his strength to control the ailerons. Also there are four pogo inputs installed between the body quadrant and the input shaft. These are to control the movement of the cables so that they are on tension at all times and not move when the dont need to. The feel and centering unit is used to position the ailerons to his neutral position. This can be done by movement of both aileron trim switches on the aft electronic panel. The aileron trim actuator can position the aileron input shaft to trim the system. The total trim the pilot have made can be read on the aileron trim indicator on the control wheel. The autopilot aileron actuator is duplicated for safety reasons. The autopilot actuator is with the autopilot input rod mounted to the aileron input shaft. This actuator will be electronic controlled by the flight control computers. All the actuators are hydraulic control led by system A and B. C:UsersTemminckDropboxHvA Projectgroep 1VProjectWerkmapKeespage 27-7.jpg 2.1.1d Output The control cables will led through the wings until they reach the aileron wing quadrant. This quadrant is kept on tension by the aileron cable tension spring. This for that the trenched out cables are kept on tension. The quadrant is connected with and pushrod connection to the aileron. On the aileron an aileron balance tab is mounted and connected with control rods. The aileron is armed with four balance panels to keep the balance in the ailerons. And this panels are equipped with fixed balance weights. The output signal of this system is that the aileron will move up or down after movement that the pilot will make by moving the control wheel. C:UsersTemminckDropboxHvA Projectgroep 1VProjectWerkmapKeespage 27-6.jpg 2.1.1e Hydraulic system The ailerons are powered by system A and B. When both of this systems fails, the aileron can still be operated manually by controlling the cables. The left aileron is powerd by system a and the right aileron is powered by system b. During normal operation of the ailerons, an aileron input goes through the input pogos of each PCU to its input crank. The upper and lower input cranks move, slides in the control valve, and supply hydraulic pressure to the actuator. The lower input crank is connected to the primary slide and the upper input crank is connected to the secondary slide. A torsion spring inside the PCU connects the two input cranks. Movement of the primary slide supplies one-half the total flow rate, and movement of the secondary slide supplies the other half. The primary slide moves to its full effective stroke before the secondary crank starts to move the secondary slide. When the primary and secondary slides move, hydraulic pressure goes through the control valve to one side of the actuator. This moves the actuator housing and the respective aileron body quadrant to the commanded position. The other side of the actuator is connected to the return. If one PCU cant supply a hydraulic pressure, its bypass valve will be activated and moves to the bypass position. This connects the two sides of the actuator, and prevents a hydraulic lock condition. When the pilot moves the control wheel, the ON side PCU still moves to his commanded position normally. As the ON side PCU moves, it also moves his respective aileron body quadrant and back drives the OFF side PCU actuator housing. When the OFF side housing moves, hydraulic fluid is pushed through the bypass valve. If one PCU input pogo cant move freely, the pilot must supply approximately 20 pounds of additional force to compress or extend the spring inside the pogo. The other PCU input pogo still moves its own input crank and slide to the commanded position. This equalizes pressure on both sides of the actuator and prevents a hydraulic lock condition. Now the other PCU can move the aileron body quadrant assembly normally. As the ON side PCU moves its respective aileron body quadrant it also back drives the OFF side PCU actuator housing. When the OFF side housing moves, hydraulic fluid is pushed through the bypass valve. During a manual reversion, the bypass valve receives no hydraulic pressure and moves to the bypass position. This connects the two sides of the actuator and prevents a hydraulic lock condition. When the pilot moves the control wheel more than three degrees, the primary and secondary input cranks hit the mechanical stops on the outside of the actuator housing. As the housing moves, hydraulic fluid in the actuator is through the bypass valve. Movement of the housing also moves the aileron body quadrant assembly to the commanded position.

Having a Second Father: My Grandpa :: Personal Narrative Writing

Having a Second Father: My Grandpa It has been five years since I have spoken to my father. I was three years old when my parents got a divorce. Both my mom and dad remarried, however my dad didn’t waste any time in doing so. After he was married, I felt that I wasn’t a part of his new life. We had our problems like any relationship between children and parents, but most of the problems resulted from interference from his new wife. We would disagree on many things because of his wife. Her inputs and thoughts that she voiced oh so well became overwhelming. I know that it is easy to disagree with a parent at any time, however it is even more so when the parent is remarried with a new life and family. Since the day that he got married our relationship drifted downhill. I thought he was so strong and would always stand up for what he believed in and wanted. He used to think that I was his world. I soon realized that wasn’t true. His wife you could say â€Å"wore the pants’ in his new family.† He should have made decisions that concerned our relationship and me but he didn’t. I never dreamed the day would come when someone would come between one of my parents and I, at most a spouse of one of my parents. I was in his life long before she and his new family came into it. I felt that I was being treated unfairly. I was supposed to be daddy’s little girl just as most girls dream about. I always thought that I would come first. The life with my mom was the exact opposite. I came first and still do in her life. She was remarried and that didn’t change the fact that I was number one on her list. I look at the days and memories with my dad and notice that somewhere along the way he got sidetracked of what was important to him. I know my thoughts seem childish, but I was hurt and felt that I had been treated unfairly. All I could think was: â€Å"What had I done to make him not love me†. As a young child, everyone wants to fit in with his or her friends.

An Unforgettable Teacher Essay -- The Teacher Who Changed My Life

I remember my fourth grade year as if it were yesterday. My homeroom teacher, Mr. Anderson, would stand at the front of the room each morning at 9:15, and wait patiently for us to say the Pledge of Allegiance. Then, like clockwork, at exactly 9:17, as my class of 28 sat down, he would set up a magic trick, pretending each day that something was going wrong during the set-up. As Mr. Anderson did this, he would often tell us a story that in some way or another related to the magic trick he showed us. Then, as he finished the trick, he would tell us the moral to the story. Â   Now a days I don't have someone there for me constantly saying what I should or should not do. I often find myself in situations in which I must be the one to decide if, for instance, I should go to a party or to the bars, or stay home and concentrate on the massive amounts of homework that have piled up. It is at times like these when Mr. Anderson's words of advice float though my head. The one I hear Mr. Anderson saying most often in the back ...

Light and Dark in Joseph Conrads Heart of Darkness Essays -- Heart Da

Light and Dark in Heart of Darkness   Ã‚   Every story has a plot, but not every story has a deeper meaning. When viewed superficially, Joseph Conrad's Heart of Darkness is a tragic tale of the white man's journey into the African jungle. When we peel away the layers, however, a different journey is revealed - we venture into the soul of man, complete with the warts as well as the wonderful. Conrad uses this theme of light and darkness to contrast the civilized European world with the savage African world in Heart of Darkness.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     In Heart of Darkness, Conrad uses light and dark to symbolize good and evil, respectively. "It is whiteness that is truly sinister and evil, for it symbolizes the immoral scramble for loot by the unscrupulous and unfeeling Belgian traders in ivory and human flesh; the whiteness of ivory is also contrasted with the blackness of the natives whose lives must be destroyed for its sake" (Gillon 25).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Two central themes occur in Conrad's Heart of Darkness. The first is the struggle between the white people and the native tribes, which plays in... ...ok and also provides its title. In Heart of Darkness, there is a real contrast between what is light and what is dark. These contrasts work within a reality of civilized and savage. It appears that light represents the civilized, and dark represents the uncivilized, but truly, white is evil, and the dark is innocent and virtuous. Works Cited Conrad, Joseph. Heart of Darkness.

Analysis of ‘Ceremony’ By Leslie Marmon Silko Essay

If Native American community adopts the ethics of white traditions that regards them as less than human being, they begin to look down on themselves. In ‘Ceremony’ Leslie Marmon Silko visibly represents this dual bind sociology called internalized domination. ‘Ceremony’ is one of the most reflective and touching works of Native American literature, a story that is itself a ceremony of curative. Tayo, a World War II experienced person of combined lineage, comes back to the Laguna Pueblo stipulation. He is intensely frightened by his experience as a hostage of the Japanese and later offended by the negative response he came across from his community. Only by throwing himself in the Indian past can he can set in motion to get back the harmony that was taken away from him. Masterfully written, full of sober magnificence of Pueblo saga, ‘Ceremony’ is a use of lasting power. ‘Ceremony’ deals with the gender roles of three women are significant to the development of a character named Tayo who is half-white and half-Indian. These three women are Tayo’s birth mother, Auntie, and Old Grandma. His mother left him when he was four years old and that began his sense of emptiness and abandonment. She could not bear to raise a child that brought the reservation shame by her mistake. Auntie raised Tayo and was the mother figure he lacked. She had no problem accepting to take him, but only to conceal the shame of her younger sister. Auntie was always hesitant toward Tayo as he was not her real son and was also a half-breed. For Tayo, this only added to his feeling of displacement and emptiness. She would give her affection and attention to her real son Rocky, but would let Tayo just sit there alone. After the war Auntie nursed him because he was all she had left after Rocky got killed. He would wake up crying after dreaming about how much Josiah had loved him and always hugged him when he was a little child. Now he realized that there was no place left for him and he would never find peace. Auntie may have been a mother figure to him, but to Tayo she was just someone who looked after him. Old Grandma, unlike Auntie, does accept Tayo and wants what is best for him. When Auntie rejected the idea of a medicine doctor because he’s not full blood, Old Grandma got angry and said that he was her grandson and why should she care what they say anyway. She has been around for many years and doesn’t worry about what other people will say about Tayo or about their family. The significance of Montano to the novel, Ceremony is very powerful and vital to the recovery of Tayo. She lives up in the rim rock and is in touch with the earth and her surroundings in every way. Being torn between the white world and the Indian world is what leaves Tayo feeling invisible and hollow inside. Montano helps him to become more in touch with his Indian side and to feel the strength and power from the earth. She teaches him the importance of certain plants, flowers, and ceremonies and how they are significant to Indian culture and survival. Tayo falls in love with her, and through his love, he begins to feel alive again. He realizes that he does have a place and that he is not invisible to everyone and to his surroundings. When he is not with her, instead of the nightmares, she fills his dreams. He woke up one night and thought about the overpowering love he felt for her. He shed tears filled his eyes and the ache in his throat ran deep into his chest. Tayo no longer feels like a walking shadow, but finally a real person with feelings and emotions. It is through Montano that he discovers himself and ultimately is able to deal with being a half-breed in a changing world. When she finally leaves him, he is able to go on living and remembering all that she taught him. Conclusion: I really enjoyed this story. It was a great portrayal of how family might mistreat you just because you are a little different than them. Sometimes people can’t deal with the fact that a family member is only half of the race that they are. I would definitely recommend this book to others, especially to anyone who feels that they are secluded and have no friends just because they are bi-racial.   Ã‚  Ã‚  Ã‚   In ‘Ceremony’, the main character, ‘Tayo’ have to come to terms with himself and his near environment upon his come back from World War II. He is distressed from a sort of post disturbing anxiety disorder which has affected him bodily as well as psychologically due to the fact that he has lived as a prisoner of war in Japan. As a result, he must deal with all of the terrible memories when he comes back to stay with his family on the Laguna Pueblo reservation in New Mexico. To complex his problems, Tayo is half Native American and half Caucasian, so he should also deal with the extra pressures of the double culture. He is torn between the Native American world and the white world, and is unable to feel a secure refuge or belonging. Tayo’s friends and family think that they know the personality of and cure for Tayo’s sickness and depression; though it is only the Native American formal procedures which will really help him. He needs to observe the junction of life and actually realize the cyclical nature of his feelings and measures that he has faced. With the help and good judgment of Old Betonie, Tayo ultimately finds harmony in the Native American ceremonial even surrounded by all of the contradictions currently in America. In Ceremony, Leslie Marmon Silko exposes the many contradictions present in America today. Be it the government’s policies concerning Native Americans, the American model of courage, or the history which the children study in their classrooms, America is full of sarcasm and paradoxes. These inconsistencies do not in any way cut down the magnificence of America as a country, but to a certain extent serve to remind its people that we do not at all times keep in mind those who helped us turn out to be what we are at present. Silko’s novel is a legendary reminder for Americans to recognize our first true nationalized custom and keep in mind that the Native American tradition is still alive and well today. Silko has demonstrated that America has made blunders in the history, but undoubtedly has the power to put right those mistakes today.

Poverty a retrospect of beliefs with the wrong reality Essay

As children we see life through a different set of eyes than others, and we accept the reality of our surroundings by how others judge us. We were the poor kids of the neighborhood and the others kids let us know that. My parents divorced when I was 5 and things were rough for my mother with 3 kids to raise on welfare. We thought we had it bad. Sometimes, we didn’t know where the next meal was coming from or who was going to help if things got worse; I remember we would stand in line to receive the food box for the month. Mom would put meals together and then she would leave for several weeks at a time, being on the road working for the Roller Derby. We never knew who our babysitters were going to be or if they were going to treat us with some sort of dignity and respect. Many times we took matters into our own hands and got rid of them and others just left, because we were not always the best behaved kids in the world, and we were always in some kind of trouble. The cops would bring us home at least 3 times a week for doing some crazy thing in the neighborhood, or stealing something from the local store to eat. After a while the cops and the store owners would just ask if we had something to eat or if there was something that we needed. Those were the days when people did come together and help others that were less fortunate, and we definitely needed the help. Our cousins lived in Firestone Park, a suburb of Los Angeles. They had some of the same obstacles to overcome except they did not have the community support that we received. My aunt was a single mother and did not receive food stamps. As I think back now on the difference between our lives, and the obstacles they faced compared to ours, we had it made. We faced challenges just as they did; I have been behind bars many times in my life. Both I and my older brother had interventions that changed our lives. My brother found out that the only way to change his life was to change his environment and look for other ways to support himself and his family than drugs. There were no food boxes available to my cousins and the cops were not as forgiving as they were in our neighborhood; the cops took my cousins to juvenile hall. There is one difference between my cousins and my family; they were half black and white. They were not looked at with the same sympathetic eyes as us and they told us about the way they were treated by the people of the city, and putting you all behind bars was the only way to solve the problem. From early on in their lives, they had to face the harsh reality that they were not treated the same as others even in their own community. Being called names by the other kids in the neighborhood, they had to fight everyday just to earn respect and they became the aggressors. They did things that we never thought of at our age, but that was the live they lived. My cousins went to juvenile hall very early on, and when they would get out, it did not take long for them to be locked up again. One of my cousins has spent over 3/4th of his life behind bars, and that is the only life he knows. We had spent a couple of days here and there in juvenile hall where they spent months throughout their teenage years. They did not have the same kind of caring community members as we did in our little part of the world; being a big city, crime was a way of life for kids there. There were not many options for the young people and joining a gang and the reality of death was just an everyday part of life. Drug abuse was prevalent and my cousins excelled in the life of crime. If it had not been for the YMCA in our community and the people that were placed into our lives, things for us could have been just as it was for my cousins. Both of my brothers have been in jail a time or two, except for my youngest brother who is spending the rest of his life in prison. He was sentenced to 25 to life, 25 to life and 18 years for crimes he was involved in 1994. I moved away from Stockton, California in 1996. My older brother moved away several years after I did and he now lives in Waldport, Oregon. He is a well respected part of the community. My journey began in 1995, after suffering a heart attack behind an overdose of Methamphetamine; I knew that I needed to change my life when I woke from the coma, and the charges that I was facing from running from the law for over 2 years. The judge whom I went in front of gave me my way out, but the road was not going to be easy. I had to complete a drug program, pay up all my fines and go to parenting classes. My kids had suffered long enough; they had to deal with all my addictions, the stealing, lying and cheating. It was going to be a battle, but I was willing to do what it was going to take to put my life back on the right track. The judge looked at me and told me â€Å"that if you do not complete this program and do all the requirements that I have set forth, that I would be facing 15 to 20 years straight time†. Thanks to the Veterans Administration and a Stockton Sheriff named Officer Garcia, the judge was going to give me a chance of a lifetime. All of the charges against me were to be dropped, and my records sealed and I would have a fresh start in life. The judge said it was against his better judgment to give me this opportunity, but I had a lot of people willing to give me a chance. He was looking forward to putting me behind bars. My cousins never had any kind of opportunities such as the one I was given and they were criminals and they would be punished to the full extent of the law. All of my cousins are in prison for life because of 3 strikes law. One of my cousins was not so lucky; He was shot and killed by the Los Angeles police that said he had pulled out a gun but none was ever found. They called it justifiable shooting, also known as guilt by association. I look back at the events of my life and realize that we were not poor by any means compared to other families in the Los Angeles area. The opportunities we had been given were not there for them and although we committed some of the same crimes, their punishment was more severe. I could never imagine being where I am today. I thank God for the people I have had in my life that gave me some different perspectives and hope that I could have more than I ever dreamed of. I look at how my cousins were raised and they way we were, and there are similarities, but we had it easy compared to them. Being of two different nationalities and dealing with the everyday stresses of the big city life must have been a burden that I am not sure if we would have survived. I must admit that life was not always rosy and wonderful, but we always had a roof over our heads and we might not have had the best meals but at least we had one. I am grateful to all the people I have had in my life that thought there was something to fight for and never let me give up hope. I pray for my cousins every day and give thanks to the lord for all that I have been given. Works Cited †.
