How does Oedipus Rex Exhibits Weakness of Character Essay
How does Oedipus Rex Exhibits Weakness of Character - Essay Example The play observed in the research begins with a plague in Thebes, the land of Oedipus. In response, he sent Creon, his brother-in-law to the oracle at the worshiping place for Apollo. Creon returned bearing the news that once the murderer of the former King Lauis had been banished, the plague will end. Then, the blind prophet named Teiresias was pursued by Oedipus for interrogation, but the prophet denied him of any answers. Oedipus threatened the blind prophet until he got the answer. Oedipus became furious when he was accused as the murderer of his father and marrying his mother that will lead to a blind life. When Oedipus went back to the palace, he saw Creon and charged him with treason. Luckily, Jocasta and the Chorus begged Oedipus for mercy. Creon was able to escape. Then, Jocasta comforted Oedipus as she guaranteed him that oracles do not work as she experienced the lies of the prophecy. According to her story, she and Laius gave their son to a shepherd to kill him using a pi n and prevent the prophecy of having their son committing the murder over his father. What really happened was the murder happened where three roads meet and five robbers were responsible for the crime that killed Laius. The story matched the memory of Oedipus so he called for the witness. Jocasta was surprised as Oedipus shared his story when he learned that he was not the son of the father he knew and he had killed a man at the crossing of three roads due to insult from his victim. (Sophocles 55). Afterwards, Polybus, the known father of Oedipus was reported to be dead. They rejoiced for a little bit as Jocasta had taken it as a proof to support her claims that oracles are worthless. The prophecy will not come true according to a messenger as Merope was not the real mother of Oedipus and he would not visit Corinth (Sophocles 95). The messenger started to reveal what he knew though the servant was the one who knew the whole truth regarding the baby who grew up to be Oedipus (Sophoc les 99). With that, Jocasta came to understand the whole truth and tried to stop Oedipus from knowing it. He did not stop from knowing the truth and got the answers from the old shepherd. He went back to the palace and saw Jocasta in a chamber hanging (Sophocles 77). In response, he took her brooch and blinded himself and set for an eternal exile. Before leaving the city, he left his children under the care of Creon while the Chorus lamented for the tragic fate that came upon their King. Oedipus had shown his strength and highness as he had shown from the start of the play. He was able to save Thebes from the sphinx and its curse by solving the riddles. Oedipus was depicted as strong and intelligent that made him a king quickly. He was also known for being wise as he can make good decisions that earned the trust of the people of Thebes (Ramphos 5). Slowly, the image projected by Oedipus changed as his fate came to his senses. He did not expect that a tragedy would approach him as he was all high and mighty being the king of Thebes. He was viewed as a savior and a hero who happened to free the people from curse. His downturn as a character was shown with his hasty decisions and actions when he got the first answer regarding the solution to the plague. It showed his swiftness in action, but that time depicted his weakness as he accused Creon of paying the blind prophet Teiresias for condemning Oedipus as the source of the plague. It seemed

White Privilege Essay Example for Free
White Privilege Essay How America came about is fascinating, and learning about immigration, rights, laws, and racism makes learning more beneficial. It helps you to understand why we, as a nation, are they way we are today, and why we will continue to be stuck in our ways. According to James Barrett and David Roediger, ââ¬Å"The Story of Americanization is vital and compelling, but it took place in a nation also obsessed by raceâ⬠¦the process of ââ¬Å"becoming whiteâ⬠and ââ¬Å"becoming Americanâ⬠were connected at every turn (36). â⬠One of the most controversial topics is white privilege and discrimination. Segregation within school systems has been a dominant problem in the past and will always continue to be. Being privileged is a something that individuals should be conscious of due to their past and understand that it is a privilege to be white rather than to be discriminated against. Becoming conscious of oneââ¬â¢s own white privilege is the first step to understand the deeper meaning of racism and discrimination. My intentions of writing this paper were to describe a situation in which I was conscious of my own white privilege. White privilege was always on my side until high school where I felt as though I was discriminated against as being a petite, white girl, from upper-class Allendale leaving me to been seen as an easy target. While at my locker one day during lunch, I was approached by two of the black students (one male and one female) and a Latino girl, and they tried to convince me something hurtful was written about me in the bathroom. Being that I am not the type to care, get involved, or respond, I turned to walk away. The Latino girl proceeded to grab my hair causing me to turn and face her and she punched me square in the face. After several minutes of back and forth wrestling and punches, the fight was broken up my teachers. It turns out that there was nothing written about me, they were just trying to get me into the bathroom to fight me, opposed to the hallway which is out in the open. All three of the students that were there were taken to the principalââ¬â¢s office immediately and suspended for two days whereas I got off free and I was allowed to go back to my day. During the duration of the day, one of the African American men left the principalââ¬â¢s office in rage and had a mission to destroy all my belongings in my locker. The boy pried open my locked and poured a bottle of soda all over my books, note books and belongings. After I reported this to our principal, he held the three students involved in the fight until one person came clean about who had been at fault for ruining my locker. It turned out, that no one admitted to it, and they were all suspended even longer than originally for not fessing up. The following week, none of the three students attended my high school anymore and I was told by my principal that they left to attend other high schools in surrounding towns. After this incident, I have never come into contact with any of them ever again. However, several of my male friends found out what happened that day and wanted nothing but to get revenge and retaliate against them and show them who runs the high school, being that whites are minority. I became very conscious of my white privilege growing up in a one-square mile suburban town of Allendale, New Jersey. My entire educational career through eighth grade consisted of white, middle-to-upper-class Americans. All the people were similar, with the same morals, values and beliefs. Everyone dressed similar and drove similar cars, partook in the same activities and hung out in specific niches. At this point in my life, I could say I could correlate my life to Peggy McIntoshââ¬â¢s article when she describes the matrix of white privilege; There was one main piece of cultural turf; it was my own turf, and I was among those who could the turf. I could measure up to the cultural standards and take advantage of the many options I saw around me to make what the culture would call a success of my lifeâ⬠¦I could think of myself as ââ¬Å"belongâ⬠in major ways, and of making social systems work for me. I couldâ⬠¦be oblivious to anything outside of the dominant cultural forms (295). It wasnââ¬â¢t until high school where I thought I would potentially move out of my small town bubble. My high school is regional; students from Allendale, along with the surrounding towns of Ho-Ho-Kus, Upper Saddle River and half of Saddle River attended. Being that I came from such a white school system, the thought of going onto high school and being surrounded by students of other races and ethnicities is something that never crossed my mind. I was never taught about the disadvantages of being white, but rather I learned about blacks and their disadvantages of dealing with racism. Over the years, little was taught about racism and what it stood for, instead we were just told that this is what happened to people when they were of different races and ethnicities back in the day. The article by Peggy McIntosh describes how whites are taught to think of blacks; ââ¬Å"As a white person, I realized I had never been taught about racism as something which put others at a disadvantage, but had been taught not to see one of its corollary aspects, white privilege , which puts me at an advantageâ⬠(291). Being white was never something that I had to deal with in or outside of school, or even within my community. I wasnââ¬â¢t necessarily shocked to walk into high school my first day to find only a select few of Latinos and African Americans. However, these were things that I never thought about or even had to think about. The few Latinos and African Americans came from Upper Saddle River and Saddle River. I was never stereotypical of these groups of people until I was surrounded with people from towns that had engaged with these people all the way up through high school. The Latinos in my school all stuck together, as well as the three African Americans that attended my high school. I feel as though this particular situation involved me having the white privilege advantage and it seems as though my white privilege helped to get me out of trouble. I should have gotten in trouble for ââ¬Å"self defenseâ⬠and throwing punches back, but I feel as though since I had never caused problems before, and they had been the center of most of the problems I was let go with no punishment. The students that got in trouble, were seen as troublesome students because of their past, where I had a clean record with no reason to suspect I was the start of the brawl. Considering my school is mostly made up of white students and entirely white faculty, when the three students got in trouble, it was probably a stereotypical decision based on non-whites. Blacks have always endured pain and agony as, ââ¬Å"â⬠¦victims of discrimination, segregation, and violence, blacks in the North encountered a powerful cluster of negative racial images. These stereotypes contributed to the conditions of racial degradation and poverty, which, in turn, reinforced prejudiceâ⬠(Takaki 107). This excerpt further explains that stereotypes stick and the negative racial images will forever be a part of the everyday lives of blacks. The primary reason of why the situation occurred, I believe dates back to sundown towns. Beginning in about 1890 and continuing until 1968, white Americans established thousands of towns across the United States for whites only. A ââ¬Ësundown townââ¬â¢ is any organized influence that, for decades, was all-white on purpose. Many towns drove out their black populations, and then posted sundown signs. Other towns passed ordinances barring African-Americans after dark or prohibiting them from owning or renting property. Evelyn Nakano Glenn helps to further explain the regulations, ââ¬Å"White controlled municipalities passed ordinances creating racial zones. When these laws were found to be unconstitutional, whites formed neighborhood associations and turned to ââ¬Å"privateâ⬠arrangements such as economic boycotts, violence, and restrictive covenants. These restrictions deprived blacks of a central element of liberal citizenship, namely property rightsâ⬠(37-38). This is proof that the African-American populations had no choice but to leave because they werenââ¬â¢t welcome. No one would support their businesses or wanted anything to do with them; they were literally driven out of these towns and wouldnââ¬â¢t stand a chance if they stayed. Being that the town of Allendale where I grew up was a sundown town, which is the most obvious explanation as to why I grew up surrounded by all whites. Moving onto high school, the other regional towns of Ho-Ho-Kus and Upper Saddle River were sundown towns as well. This plays a huge role in the situation at my high school because people of color and different races are focused on more and white students carry all the dominant privilege. If I had been a different race I think the entire situation would have never occurred because I would probably be a person that was known for affiliating with them. If I had been black, I would have probably felt like I should stick with the other three black students in the high school. The situation would have been the same if I were Latino or another race. Segregation still takes place in America and being one of only a few black families within your community will be a repetitive cycle for black families looking to move to our dominantly white community. According to Douglas Massey; ââ¬Å"When avenues of spatial assimilation are systematically blocked my prejudice, and discrimination, however, residential segmentation increases and persists over time. New Minorities arrive in the city and settle within enclaves, but their subsequent spatial mobility is stymied, and ethnic concentrations increaseâ⬠¦whereupon group members are forced to adjacent areas, thus expanding the boundaries of the enclaveâ⬠(225). I feel as though since my region of New Jersey is predominantly white, what would things change now? Why would blacks and ethnic families feel inclined to move to a neighborhood where they stand out? Especially for African-American families, my town along with the surrounding towns do not sell African-American hair products in any of my supermarkets or pharmacies nor are there salons where African-American women can go to get their hair braided. My community has adjusted to the white population and being that my town is so small, I feel as though it would take dramatic lengths to change the way our community functions. Being white, I feel as though I benefited from the whole situation because I did not get in trouble for punching the girl back, and I did not get suspended. I was allowed to return to my day at school as though nothing happened while they were kept in the front office until school was let out and were suspended for the rest of the week (2 days). This experience made me think about my race in a different way because I had never encountered issues with non-white people, because I was never around them. Coming from a primarily white school, white students stand to make white privilege stick out like a sore thumb. It helped me to understand that white people dominated my school population and that this would have never been an issue if the school had always been made up of a majority of other races and ethnicities. It is as if the select few minorities felt as though they needed to stand up for themselves and prove that just because there are so few of them they can still ââ¬Å"runâ⬠the school. The three students involved, I feel, chose to leave due to feeling like they were discriminated against and treated differently than other students. They could have felt mistreated or felt that being out numbered was a disadvantage for them. Moving to surrounding schools definitely made them feel like they belonged better because I know there were mixed groups of people outside of our high school district. Being that ninety-nine percent of my school was white could have made the few students feel intimidated and make the white students angrier and feel the need to gang up on them after this incident, almost to prove their white privilege. This incident correlates to issues of citizenship and my ability to participate as a full and equal member of American society because I suffered no consequences from the incident except for a bloody nose. A bloody nose is a temporarily occurrence but because of what happened, it hasnââ¬â¢t affected me being a full and equal member in the American society. It has however, affected the minority students at my high school, and drove them away. As described by Evelyn Glenn, ââ¬Å"At its most general level, citizenship refers to full membership in the community in which one lives. Membership in turn implies certainâ⬠¦reciprocal duties toward the community (37). â⬠These black students are citizens but they do not live in a community with other African-Americans reside. They can be still be involved in the community but the families as a whole might not be as eager to get involved as they are outnumbered and may feel their voices may not be heard or make a difference. There are a few potential long term consequences of white privilege for myself that will be with me as long as I live. Being that Quinnipiac University is not very diverse, but more diverse than my high school, it was difficult to get used to seeing people of color and different ethnicities every day. I do not believe growing up in an all white community has been beneficial to me, and I wish I was more natural around people of different races and ethnicities. It is unrealistic to say that I will never have to deal with this, but in the real world, and when finding a job, you will be presented with a variety of people that may even become more of friends rather than co-workers. Someoneââ¬â¢s accent or skin color does not determine what kind of person they are, it is their personality that makes them who they are. I also believe in regards to the incident, if I had been at fault, and was suspended for my actions of self defense, I would have not been able to attend a prestigious school such as Quinnipiac. When applying for colleges, most applications ask if you have ever been suspended, such as the Quinnipiac application which asks if you have ever been suspended or missed significant time from school. I would have then had to explain the situation and how I was suspended for self defense. If colleges see that you are a troubled student, and have a record for misbehaving, they will not accept you to their school. Community colleges of lower rankings will be more willing to accept a student with a past, rather than a private school like Quinnipiac University. Discrimination and segregation still exist today. The past makes up the present so learning about what people of all races and ethnicities went through in history is important as a citizen of the United States. Everyone, in some way, or somehow, has dealt with discrimination whether it is you or friends and family. While on the other hand, it is imperative to pay attention to your privileges and understand what it means to be American. Works Cited Barrett, James E. , and David Roediger. 2005.

Roman City Planning Essay -- Rome History Roman Historical Essays
Roman City Planning à à à à à The design and structure of a city is as important as the people who dwell within her walls. The placement of streets and the structures built there are carefully plotted for optimal use. Foot and cart traffic, fire hazard, and access to water were all key factors in city planning. Eventually the Romans had fine tuned their design principals in such an advantageous way that they molded all of their city states similarly. à à à à à Rome developed from the combination of small farming communities around a hilltop fortification. The city, which was founded before regularized city planning, consisted of a confusing maze of crooked and gnarled streets. The focal point of which was the cityââ¬â¢s forum, the main meeting place and site of the many religious and civic buildings such as the Senate house, records office, and basilica. (Rich, 20) Augustan Rome, with a population estimated at between 700,000 and one million, was the only megalopolis in the West. Romeââ¬â¢s street plan, which at its greatest extent had 85 km of road, was an irregular maze. Most streets were footpaths or could accommodate only one cart at a time. The central city had only two viea (streets on which two carts could pass each other), on opposing sides of the main forum. (Nicholas, 6) A law passed under Julius Caesar, which was still in force well after his death, stated that carriages were forbidden to use these streets by day, since it was found that there was not room in them both for wheeled vehicles and pedestrians. Public streets would be decorated with marble and stone, some houses, as they decayed, have revealed alleyways and passages that existed before reconstruction. (Bowra, 34) Main streets were often designed carefully to accentuate the housing and monuments that would appear on any given street. Side streets would often be no more than passages, with flights of steps, and sometimes scarcely broad enough for two people to pass in comfort. Many streets were colonnaded; a Roman technique intended to bring shape to shadow and direct light through the streets. Earlier centuries used the stoa, or free-standing portico, to give effects of light and shade to their constructions. It is suggested that the colonnaded street developed out of the stoa; and partly also, perhaps, out of the thrifty use of available space, with the upper stories of houses jutting forw... ...ordinated plan of the city. The main streets led directly from the center of town to the gates, and the pomerial road ran around the city immediately inside the walls. (owens, 150) Rome was a living organism constantly changing and evolving as all cities do. However, the design and structure of Rome was born out of knotted roots. The placement of streets and the structures grew from dirt roads to paved passage ways meant to convey movement and beauty. Key factors in city planning revolved around the citizens and their needs. The Roman design principals forged a template by which all of their city states were similarly molded. Works Cited Bowra, Maurice Et. Al. Golden Ages of the Great Cities.

Expository Essay on Exercise and Obesity Essay
Some say that a decreased amount of sleep time can be associated with the increase of body fat. Insomnia or sleep apnea or even RLS (restless sleep syndrome) are just three out of many different types serious sleep that can also in fact lead to all kinds of increased risk several other chronic health problems. Multiple studies have explained the sudden impulse of these sleep disorders and the links its shares on obesity, these are very important links in contemplating the relationship between sleep disorders obesity. Physical fitness and good eating habits are important prognostic tools in obesity and chronic disease; there are several studies that have examined the likeness between obesity, sleep disorders, and exercise. It also explains how different sleep disorders may impact the physical fitness regimen responses and how extremely overweight may impact lifestyles of the patients with regard to sleep disorders will also be reviewed.

Roman Plebeian Tribune Definition
Roman Plebeian Tribune Definition The Plebeian Tribune- or tribuni plebis- is also known as the tribune of the people or the tribune of the plebs. The plebeian tribune had no military functionà but was strictly a powerful political office. The Tribune had the power to help the people, a function called ius auxilii. The body of the plebeian was sacrosanct. The Latin term for this power is sacrosancta potestas. He also had the power of the veto. The number of plebeian tribunes varied. It is believed there were originally only 2, for a short time, after which there were 5. By 457 B.C., there were 10. The Plebeians Secede The office of plebeian tribune was created in 494 B.C., after the First Secession of the Plebeians. In addition to the two new plebeian tribunes, the plebeians were allowed two plebeian aediles. The election of Plebeian Tribune, from 471, after the passage of the lex Publilia Voleronis, was by a council of plebeians presided over by a plebeian tribune. When the plebeians seceded in 494, the patricians granted them the right of having tribunes with greater power than the patrician tribal heads. These tribunes of the plebs (plebeian tribunes) were powerful figures in Romes Republican government, with the right of veto and more. A patrician, Claudius Pulcher had himself adopted by a plebeian branch of his family so he could run for the office of plebeian tribune under the plebeian name of Clodius.

Enzymatic Reaction in a Reaction Essays - Catalysis, Free Essays
Enzymatic Reaction in a Reaction Essays - Catalysis, Free Essays The purpose of this part of the experiment is to find out the course of an enzymatic reaction in a reaction. In order to do this, a measurement of the amount of substrate disappearing over time increments of 10, 30, 60, 90, 120, 180, and 360 seconds had taken. In this experiment we see that as time progressive the enzymatic rate lowered. The highest rate is the first in the first time interval (0-10) . It was the highest because iit had the highest catalysis amount and the most amount of H2O2 to decompose. The lowest rate was the last time interval (180 -360) there are 2 possible reason why it is the lowest. One is the H+ content makes the solution more basic. This moves the solution away from its optimal ph, thus causing the enzyme to denature. Denaturing is when the enzyme becomes biologically inactive because the proteins begins to unfold. Another reason could be is that all the catalysis amount is at the lowest because all the enzymes are already being used. This causes an inhibi ting effect on reaction. Inhibiting is when the reaction is stopped or slowed down. If we were to lower the temperature it would still cause the enzyme to denature. Like ph, enzymes also have an optimal temperature if the temperature gets too low or too high it will denature. Testing the concept of the amount of substrate decomposed in these time amounts helped to determine the enzyme reaction. The dependent variable was the amount of hydrogen peroxide, sulphuric acid and water that were combined in the beaker while the independent variable was the amount of time the reaction was allowed to take place before the KMnO4 was added to stop the reaction. This experiment measures the disappearance of substrate which is Hydrogen Peroxide H2O2. In this experiment the level of KMnO4 the burette dropped from 5 ml to 0 ml. This means that the level of KMnO4 dropped 5.0 ml. These results are important because the baseline is used in every experiment. The baseline is used to test the amount of H 2O2 in a 1.5 solutions. At low concentrations, the graph will show an increasing rate of reaction as concentration increases, levelling off at higher concentrations. The shape is explained by the concentration of substrate directly affecting the rate of reaction until another limiting factor becomes more important. Reaction that were involved in this experiment was : 5 H2O2 + 2 KmnO4 +3 H2SO4 K2SO4 + 2 MnSO4 + 8 H2O + 5 O2 2 H2O2 2 H2O + O2 Without catalase this reaction occurs spontaneously but very slowly. Catalase speeds up the reaction notably. This reaction was studied by measuring the disappearance of the substrate. For example, hydrogen peroxide (H2O2) is converted to water (H2O) and oxygen (O2) gas. Catalysis speeds up the reaction and sulfuric acid (H2SO4) stops the reaction by lowering the pH and denaturalizing the enzyme. The rate is the highest in the first ten seconds because the rate decreases as the concentration of the catalase decreases over time.The rate is lowest during the last time period of 360 seconds because the most time has passed. The catalase concentration has been reduced and the product amount has increased, blocking the enzymes from reacting with the hydrogen peroxide. Miscalculations involving numbers and amounts of solutions would have a severe effect upon the results. Mathematical errors may also have of occurred. When the catalase arrived, it had melted. Because it is to remain on ice at all times, this may have caused errors. The age of the hydrogen peroxide effected results. For example, when calculating the percent of hydrogen peroxide spontaneously decomposed after 24 hours, new hydrogen peroxide yielded a much higher percentage than the aged hydrogen peroxide. Conclusion By performing this experiment ,the quantity of a substance in different solutions is determined through the titration method. The rate of how quickly the catalsye enzyme was able to convert Hydrogen Peroxide to water and oxygen gas also recorded, which helped to expand our knowledge of the importance enzymes and how they function. From the graph , catalase, or enzymes, drastically increases the rate of hydrogen peroxide decomposition but the rate of reaction
