The Oppression of Caliban free essay sample

This paper analyzes the role of Caliban in Shakespeares The Tempest. This paper is about how the characters in Shakespeares The Tempest see Caliban as a monster. The writer examines the character and proceeds to compare and contrast him to each of the other characters in the play. The writer also debates about whether or not their treatment of Caliban is justified. William Shakespeares, The Tempest, provides insight into the hierarchy of command and servitude by order of nature. This play uses the relationship between its characters to display the control of the conqueror over the conquered. It also shows how society usually places the undesirable members at the bottom of the chain of command, even though they may be entitled to a higher social status. For example, the beginning of the play opens with a scene on a boat in the midst of a terrible storm. The boatswain, who is under the command of the royal party, attempts to keep the boat from sinking. We will write a custom essay sample on The Oppression of Caliban or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Members of the royal party, however, persist in interfering with his duties. The boatswain retorts, What cares these roarers for the name of the king To cabin! Silence! Trouble us not(I, I, 16-18). He is trying to warn his superiors that if he does not let him do his job, everyone will die, and it will not matter who has power over whom. The superiors, however, still take offense to this comment and label him a blasphemer. Caliban, an unfortunate character in this play, suffers from similar constant abuse because he is of the lowest social rank in his community. Critic John W. Draper describes Calibans position in relation to the other characters when he says, Of all the characters in Shakespeare, Caliban is the most fully and repeatedly/ described, though not always consistently; and his bodily parts seem to show little/ relation to his humor or his character except that both are monstrous. Monsters/ were popular; and, as Trinculo remarks, any holiday fool in England would pay out/ silver for the sight of one. Calibans monstrosity, however, out-Herods Herod`(Draper 89). According to the other inhabitants of the island, Caliban is a monster. He is a symbol of what they never want to become. Caliban reminds them to act as though they are worthy of their high social status. He is the painfully realistic entity around whom the other rulers on the island silently rally in order to maintain a social balance. They abhor him but desperately desire to possess at the same time. On a narrower scale, the oppression of the underdog is obvious in the undesirable Caliban and his relationship to Prospero, Miranda, Ariel and Ferdinand. `

The first view we get from Douglass is as a small boy, without a birthday, father, or any sort of identity. â€Å"I have no accurate knowledge of my age †¦ A want of information concerning my own was a source of unhappiness to me even during childhood.† (p. 39) Learning and knowledge make all the difference in the world, as Frederick Douglass proves by changing himself from a slave to a widely respected writer. You can’t judge a book by its cover, if you look within the person you will see someone unique and through learning a world of difference is made. The main focus of this essay are the many struggles Douglass came upon through slavery and strategies on how he overcome them. In times of severe emotional and physical abuse, most people turn to their families for support. Frederick Douglass was subjected to emotional and physical abuse. Slaves were property of the slave owner, so, the slaves were continuously traded and families were constantly broken up. Having few blood ties to turn to, Douglass had to find other means of creating a family that would help him deal with the daily issues of slavery. Slavery destroyed any attempt towards having a normal family but he tried to create a family in different ways in order to survive his own conditions. Since his family was torn apart disrupted by slavery at very early age he had to form a family. Douglass never knew who his father was; though he heard about the possibility that his master might be his father. He had been torn from his mother’s arms when he was twelve months old and was taken to a plantation. Douglass’s only memory of his mother, who died when he was seven, was a memory of her walk ing twelve miles to tuck him in at night. His only family that remained for him to look to for comfort was his grandmother and his Aunt Hester. He lived with his grandmother on the edge of the plantation. His grandmother was put to raise the children of the younger women. It was impossi... Free Essays on Freedom Free Essays on Freedom Anytime a person writes an opinion on anything to do with September 11, there is always room for controversial issues that tag along. Declan McCullagh wrote a piece on how national security overrides America’s personal liberties in time of war and McCullagh believes that â€Å"During all major wars, the government restricted Americans’ civil liberties in the name of quelling dissent, silencing criticism of political decisions and reserving national security† (535). He gives examples that support his claim, examples that are very supportive, though he doesn’t state his stand on the issue. He uses moral equivalence, a very good argumentative defense, to convince his readers of his belief. He compares all the past wars with his belief on how personal liberties have been affected, and proves them throughout his essay. McCullagh gives examples from all of America’s major wars (the Civil War, WWI, and WWII) and shows how personal liberties of Americans were in fact affected. Though he doesn’t state whether or not he agrees with the matters he speaks about, he does prove through his examples that the event has actually happened and the personal liberties were indeed affected. His best argument in my eyes is his statement about WWII. Executive order 9066 authorized President Roosevelt and the military to remove Japanese-Americans from Americas west coast, home to America’s military bases. As unfair and judgmental that may seem, this act was kept silent until years after the war (537). The personal liberties given to the people of this country are protected by the Constitution of the United States. But at time of war, should congress or the President have the authority to alienate a certain race of people for safety while breaking the rules of war set by our forefathers? Like I said above, anytime a person writes about September 11, or any war for that matter, there is always room for a contradiction in any opinion. McCullagh s... Free Essays on Freedom Government’s Opinion of Freedom Vs. The Definition of Freedom In the song â€Å"God Bless the U.S.A.,† the lyrics are â€Å"I’m proud to be an American where at least I know I’m free, and I won’t forget the men who died that gave that right to me.† Many years ago, our four fathers put together the Constitution in order to insure us that we are and always will be free. What does freedom actually mean? Freedom means carrying out ones own actions without coercion or constraint by necessity or circumstances. Today the government’s opinions of freedom share some of the same characteristics as the definition, but their opinions have too many limitations to actually classify our country as completely free. The First Amendment of the Constitution was written to guarantee one’s freedom of religion. This amendment prohibits congress from setting up or supporting an official church. In addition, it forbids congress from passing laws limiting worship. The First Amendment states that congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof. Although this may be true, this does not mean that all religious practices must be allowed. In fact, congress prohibits multitudinous amounts of religious worship. Religious ceremonies of cults, worshiping the devil in prison, and acts similar to the Klu Klux Klan are exceptionally forbidden. For example, Mormons believed that it was a man’s duty to have more than one wife; still the Supreme Court ruled that Mormons had to obey the laws forbidding that practice. The First Amendment also guarantees freedom of speech. It says that congress shall make no law abiding the freedom of speech, or of press; or the right to peacefully assemble, and to petition the government for a redress of grievances. Nevertheless, the government still manages to limit our country from some protected speech. Often, the time, place, and manner are re...

All About Eve and the Roles that Women Play

All About Eve and the Roles that Women Play Joseph Mankiewicz’s All About Eve explores the inability of women to find fulfillment in the roles offered by the theater. For a â€Å"true star† like Margo or simply a â€Å"carbon copy† like Eve or Phoebe in the harsh world of the theater, Mankiewicz suggests that it is almost impossible for a woman to reach fulfillment. This dilemma is largely due to the transitory nature of success, and the possibility of another star constantly in the making. As a result, only the role of the self-effacing and docile female can succeed in the world of theater. Mankiewicz suggests that women can only find fulfillment in the role of a docile and humble housewife, while the men must be the breadwinners of the family. This is exemplified by Karen, the ideal female spouse whom supports her husband’s endeavors and does not cultivate a separate image apart from that of being his wife. Moreover, whilst Karen may be the â€Å"lowest form of celebrity†, she enjoys an ostentatious and lavish lifestyle, as indicated by her array of magnificent costumes throughout the film. Unlike Margo, Karen yields no anxieties nor any â€Å"paranoiac insecurities†, but rather displays undying devotion to both her friend and husband, and is thus praised by Lloyd as his â€Å"loyal little woman†. Not only does this reflect the paternalistic values eminent in society in the 1950s, but is also an endorsement, on behalf of Mankiewicz, for those female characters who accept their subservient roles. It is through Karen that Margo realizes her desire to play the role of a humble housewife is greater than that of a professional woman. Such two roles are constantly conflicting in Margo’s life, and are the primary cause of her deep rooted anxieties. Whilst seemingly at the height of fame and power, she expresses her discomfort in the incongruity of playing women who are half her age when revealing to Lloyd that she has reached the big â€Å"four-oh,† at Bill’s birthday party. Moreover, as Margo wearingly sits by the piano brooding, requesting for Liebestraum to be played on repeat, close ups of her face reveal her fear of becoming an ageing actress capable of being marginalized by a younger and attractive understudy. Ultimately, and despite her numerous accolades, Margo finds her professional career to be unfulfilling, as she reveals to Karen with an air of resignation that â€Å"nothing is good unless you can look up just before dinner†¦and there he is.â €  To reinforce his ideal that women must sacrifice their professional careers for a happy domestic life, Mankiewicz juxtaposes Margo’s anxieties with her genuine happiness when casting Bill adoring looks in the Cub Room, the night before their marriage. The role of the â€Å"carbon copy† as played by both Eve and Phoebe, reveal both the exclusivity of the theater and the transitory nature of success. Eve’s introduces herself to Margo through playing the role of the wounded war widow, literally climbing the theater’s stairs in an attempt to reach the top of the professional ladder. At the height of her deceptive powers, she begins by makes herself indispensable to Margo, adopting the roles of her â€Å"sister, lawyer, mother, friend, psychiatrist and cop† in an attempt to ingratiate herself to her, and ends by blackmailing Karen in the ladies’ room to obtain the role of Cora in Lloyd’s play. However, when accepting the Sarah Siddons Award, close ups of Eve’s expressions reveal her disappointment at Margo and Karen refusing to congratulate her, Margo instead prodding her with the trophy, murmuring, â€Å"Go put that where your heart ought to be.† Furthermore, Mankiewicz’s introduction of Phoebe through the reflection of Eve’s mirror, suggests to the audience that there will always be an infinite reflection of â€Å"carbon cop[ies]† willing to do â€Å"all that, just for a part in a play†. Therefore, in the viperous and competitive world of theater, Mankiewicz infers that success is transitory, and that the demise of one star will lead to the birth of another. Therefore, despite being at the height of their fame and success, both Eve and Margo suffer in the professional world of the theater. This is a result of the infinite role of the â€Å"carbon copy† which leads to their demise, and therefore revealing the transient nature of success. It is only Karen, who vicariously lives through her husband and accepts her subservient role as a docile housewife, who is content with the role that she plays.

Definition - Essay Example Many people have shown the attitude to persevere despite of the difficulties. As a result, they have helped and inspired many to do the same. In this paper, perseverance is defined in three distinct ways: the capability to endure hardships, hard work and committed to the task. Likewise, it will present three famous persons who have shown these characteristics and placed them in the pedestal of success making them good examples to young people. Perseverance is a virtue that entails the ability to endure many adversaries towards the attainment of a goal. This is something Helen Keller showed in her own life journey. We all know that Helen Keller wrote many poems and stories that are widely read by people young and old alike. The inspiring thing about her is that she is blind and deaf. Helen was born on June 27 1880 with the sense of sight and hearing. However, an unknown illness struck her when she was about a year and a half years old. Everyone in her family thought she was going to die. And then unexpectedly, after a few days, she got well. However, her mother noticed that Helen no longer responded to sound (like the ring of the bell) or sight stimuli. They then concluded that the illness has left her a mark which she suffered for the rest of her life. Towards her childhood years, Helen has been very hard to manage particularly when she throws tantrums and screams towards other members of the family. Upon the recommendati on of the family's friend Alexander Graham Bell, Helen's family finally decided to look for a teacher at the Perkins Institution and Massachusetts Asylum for the Blind. Although difficult at first, Helen struggled to learn how to spell words using hand signals. With the efforts of her teacher Ann Sullivan, she continued to improve and master her skills despite of her condition. The highlight of her education happened when Anne brought her to the lake and spelled "water" in Helen's hand and the later immediately understood. From that moment, Helen's improvement was astounding as she could spell thirty new words that day including Anne's name. After this incident, Helen became famous because of an article that was written about her achievement. Eventually, she was also given a teacher to train her how to speak. Helen tried all her efforts to learn how to speak but was unsuccessful because her vocal chords were not fully developed. Still, this didn't stop her from pursuing her dreams. On 1891, she wrote the Frost King as a birthday gift for her friend Michael Agnos. Helen was also recognized as the first deafblind person to enter and finish a Bachelor of Arts degree in a higher learning institution. However, it was not easy for her as tons of school work further led to the deterioration of her eyesight. Helen soon travelled around the world giving lectures about her experiences. She has been an ambassador of faith and determination to many people. Perseverance also shows the spirit of service and commitment to people. Franklin D. Roosevelt is one of the famous American presidents because of the policies and political changes he started. His leadership started just in time when the unemployment rate is high and the economy was in slump. He proposed a program to bring relief to those who are unemployed, recover losses in business and enacted some reforms for the citizenry. Despite of all

Understand the Effects of Sport in the Development of Children Essay Example for Free

Understand the Effects of Sport in the Development of Children Essay Social effects Children who regular play sport have showed differences compared with those who dont. There are many social factors but I have highlighted the main ones. These social factors can be used later in life maybe to have respect for work colleagues. Learning respect for others When participating in local sports teams children tend to have respect for their team mates, but also their opponents. Due to the sex difference during school boys tend to be outside whereas girls play indoors. Because of boy playing sport outside they tend to learn goal setting, independent roles, techniques to improve performance and settle dispute. Whereas girls tend to cooperate better and have good patience. Development of coping ability When children play matches or games there are only one winning team but there is also a losing team. When losing the children will have to cope with disappointment and have respect for teamwork and the opposing team. When winning it will teach the children to have respect for the opposing side. Improved cooperation skills A successful team will need to cooperate to do well in a competition, so when children play in a competition in a team sport the performers will need to cooperate with each other, when older they can cooperate with people and consider other peoples feelings and views. Improved emotional wellbeing Participating in regular sports can decrease stress, it has been shown that boy and girls who play for teams have shown a greater ability to relax and avoid headache and back pains to those who dont play regular sports. Psychological effects Playing sport at an early age can have psychological effects which include an increase of motor skills, development of a sense of success and failure, these all can be used later in life. Increase range of motor skills Coaches and family encourage their children to play a range of sport because regular participation in sports improves hand eye coordination, coordination and balance. This means they will be good at a range of sports and when they grow up they can use these motor skills to understand tasks. Greater confidence and self esteem Children who participate in sport tend to more confident in their abilitys compared to those who dont. This means they will be comfortable in social situations and when a challenge comes across they will find a solution. Developed sense of success and failure As a regular participant in sport you will have to face success and failure when losing you will need to accept your loss and look where you went wrong, when winning you will need to have respect for your opponent. Increased motivation Children play sport for many reasons they can include pride, challenge of competition, desire and determination to succeed. These reasons will make children determined and motivated to succeed in their sport. Physiological effects Physiological effects can include a number of factors which include improved general health and improved fitness. Improved general health Sports serve as an excellent physical exercise. Those who play sports have a more positive body image than those who do not. Playing sports often involves physical activities like running, jumping and stretching and moreover a constructive expenditure of energy. Playing sports since an early age strengthens the bones and muscles and tones ones body. Thus sports provide the body with a complete exercise. Improved fitness After all, nearly every sport involves some kind of physical exercise, which is one of the key components of a healthy lifestyle. While a single sport can still do wonders for your body, by participating in a variety of them, you can work different muscles. For example, while football is more about strength, rugby involves more speed.

The Jungle :: essays papers

The Jungle From the point of view of history, The Jungle, is both a comment on and a product of its own times. Those times most definitely need to be viewed in relation to what happened in the last half of the nineteenth century. This incredible time period saw the making of great industries and great fortunes (for those who were in control of the industries). So far as the relationship between business and government was concerned, it was a time of laissez-faire, where government had very little to do with what business was doing. If as Calvin Coolidge said in the 1920’s, ‘the business of America is business,’ what did this mean for individuals, their rights and expectations? The Jungle appeared in January of 1906. It is completely understandable to me that the reading public responded to details on meat production and plant sanitation instead of the conditions of workingmen or Sinclair’s Socialist message. In turn, The Jungle helped to do something completely different than what the book’s author meant for it to do. The Jungle helped to push the Pure Food and Drug Bill out of a House committee and force president Teddy Roosevelt to jump into action. Roosevelt quickly requested the Department of Agriculture to send an investigating committee and through additional pressure, including Sinclair’s personal appeal, Roosevelt sent in an additional committee (Neill-Reynolds Commission). Also, at the same time a Beef Inspection Act was submitted in the Senate, all of this with Roosevelt’s complete approval. Somehow, when the meat industry found out about all this they were able to get articles published which defended present practices. Since Roosevelt was not able to exert the pressure he himself felt, he released a portion of the Neill-Reynolds report, which basically confirmed the truths of the packinghouse conditions that were depicted in The Jungle. It is my opinion that the fact that The Jungle could cause such a large industry to fight back powerfully attests to its own power as a persuasive medium. Upton Sinclair’s often quoted remark about aiming for the heart and hitting the stomach definitely rings true when reading The Jungle. Most readers mistook it for another muckraking effort, on unsanitary conditions in the packinghouses. If Sinclair had not written the last three of four chapters of the book then it would have read much more like a social protest novel. Most definitely the purpose of The Jungle is to promote socialism as the only answer to the wage slavery enforced by capitalism.

Gravimetric Determination of Phosphorus in Fertilizer Samples Essay

I. Abstract The purpose of this experiment is to determinethe Phophorus content of fertilizer samples using Gravimetric Analysis. It involves dissolution of the fertilizer sample, precipitation and heating and cooling of the sample. Pooled standard deviations of the two data sets for % Pwet, %Pdry, %P2O5 wet and %P2O5 dry were 5.1448, 5.1472, 11.8436 and 11.8504 respectvely. During the experiment a data rejection for %P and %P2O5 was concluded at approximately 20% and 47%. Determination of the Phosphorus content in fertilizer is vital in quality assurance and in the choosing of a fertilizer grade important for agriculture. II. Introduction Plants require essential nutrients such as Nitrogen, Phosphorus, Potassium or Sulfur to grow. However, most soils lack these macronutrients thus a decrease in food production. In connection with this, the use of fertilizers containing these macronutrients has been part of the agricultural tradition. Fertilizers have in its labels a set of numbers, known as the fertilizer grade that always appear in the form N-P-K, indicates the proportions of essential nutrients present (ie 10-10-10 which means 10% Nitrogen, 10% Phosphate in the form of P2O5, 10% Potassium in the form of K2O). Different organizations worldwide like Association of American Plant Food Control Officials (AAPFCO) in the United States, conduct different tests to assess the accuracy and consistency of the nutrient content with regards to that of the product label and also to ensure quality assurance as part of consumer rights. Analysis of fertilizer can be conducted using Gravimetric Analysis. In Gravimetric Analysis, the product with known composition is resulted from the conversion of the analyte to a soluble precipitate that can be easily filtered and is free from impurities by subjecting it to heat. This product of known composition will then be weighed and the percentage of the analyte in the sample can be determined. In this experiment, the analyte, Phosphorus in the fertilizer will be precipitated as Magnesium Ammonium Phosphate Hexahydrate, MgNH4PO4 ( 6H2O: 5H2O + HPO42- + NH4+ + Mg2+ + OH- ( MgNH4PO4 ( 6H2O (s) (1) The purpose of this experiment is to determine the percentage of Phosphorus (P) and Diphosphorus (P2O5) in the fertilizer sample by the means of Gravimetric Analysis. III. Data and Results In this experiment, the wet (as received) and dry weights of the fertilizer sample, obtained from the previous experiment of moisture determination of the same fertilizer sample were used. Weights were divided into two data sets, Data Set 1 having four (4) trials and Data Set 2 having three (3) trials. The dried sample from the previous experiment from which moisture was determined, was dissolved and is converted into a sparingly soluble precipitate, MgNH4PO4 ( 6H2O which is then filtered and weighed. The filter paper used was weighed to easily determine the weight of the precipitate. The precipitate was then dried and weighed. IV. Discussion This experiment aims to determine the percentage of P and P2O5 in fertilizer sample using Gravimetry. The fertilizer sample from the previous experiment of Moisture Determination was utilized in this experiment. The dried fertilizer sample was dissolved with 40 mL distilled water and was then filtered to obtain a clear filtrate. In Gravimetry, it is important to use a precipitating agent that if not specific, should be selective and would give out a precipitate containing the analyte. This precipitating agent should also give out a precipitate that is easily filtered and washed from impurities, unreactive with the elements present in the atmosphere, of low solubility to lessen the loss of analyte during filtration and washing, and with known composition after drying or heating. In this case, 45 mL of 10% MgSO4 ( 7H2O was added to the filtrate, with 150 mL 2M NH3 as the precipitating agent to obtain the desired precipitate MgNH4PO4 ( 6H2O which contains the analyte P. See Equation 1. While other precipitating agent like NH4Cl can be used, NH3 was used otherwise to ensure that the desired precipitate would be form. The presence of Cl- ions will more likely to attract Mg2+ thus producing MgCl2 precipitates, which do not contain the analyte in this experiment which is P. It should be noted that NH3 is added slowly with continuous stirring to the solution to ensure the growth of the precipitate, resulting to a precipitate that is easier to filter and be freed of impurities. This technique is related to the von Weirman’s ratio wherein the particle size of a precipitate is inversely proportional to the value of Relative Superaturation given by: Relative Supersaturation = [pic] Where: Q= concentration of reactants before precipitation S= solubility of the precipitate Precipitates are either formed by nucleation, or by particle growth. In nucleation, particles join together to form a large mass, usually a result of supersaturation in solutions. It consists of huge amount of precipitate, however, is composed of small particles that are hard to filter. In this experiment, what is desired is particle growth that yields a precipitate of large size but of smaller number. This is possible by further precipitation wherein particles adhere to the surface of initially nucleated particles. The supersaturation state of the solution is eased during constant stirring upon addition of the precipitating agent, thus promoting particle growth rather nucleation. With respect to the von Weirman’s ratio, the higher the value of the ratio, the higher the possibility of getting smaller particles, thereby promoting nucleation, contrary to a lower value of the ratio which promotes particle growth that will yield larger precipitates that is important in this experi ment. After the addition of the precipitating agent with constant stirring, the mixture was allowed to stand at room temperature for 15 mins. It is important to let the mixture stand, without any agitation or external forces acting on it to let digestion to occur. Digestion is necessary to allow reprecipitation, wherein particles will adhere to the initially small precipitates, and to expel water molecules thus lessening the surface area available for adsorption which causes impurities to obtain larger particles with greater purity and easier filterability. After 15 mins, the mixture was filtered using the preweighed filter paper. The filter paper that was preweighed was kept in the dessicator until further use to keep the moisture from adhering to the filter paper. Preweighing the filter paper was helpful for easy determination of the weigth of the precipitate. During filtration, precipitate was washed with distilled water in small portions of 5mL twice. For each washing, the distilled water was poured into the beaker where precipitation occured to accumulate the remaining precipitates that adhered to the sides of the beaker. After washing with distilled water, two 10mL portions of 95% ethanol were used for second washing. The use of 95% ethanol, becaue of its volatility thus will dry the precipitate faster, will ensure that no more water is trapped in the pores between the precipitates, minimal solubility loss and particles of small size will not loosen up and pass through the pores of the filter paper. Smaller portions of the wash liquid were used to ensure that the precipitate will still be intact and nosignificant loss in the amount of the precipitate due to the overflowing of washes liquid. The filter paper containing the precipitate was then heated inside the oven set a t 110˚C for 1 hour and was cooled in a dessicator for 15 min. After this, the weight of the precipitate was determined by subtracting the value of the preweighed filter paper with the weight of the filter paper including the precipitate. Even though Gravimetry is considered as one of the efficient and less expensive ways of determining a fertilizer component, this technique is still not fool proof and errors due to determinate and indeterminate factors may lead to an erroneous result. One of these errors is the fast addition of the precipitating agent and low impact of agitation that leads to the production of larger amount of small particles that may pass through the filter paper thus having lesser amount of precipitate, and a lower value for the P or P2O5 content in the sample. On the other hand, since while the mixture stands in room temperature without any coverings, contaminants like dust particles may be included in the mixture, contributing weight to the precipitate, giving a higher yield. This high yield will give a P or P2O5 content of the sample higher than its actual value. It can be observed from Table 3 that the range of % P and % P2O5 lies between approximately 6% to 13% and 15% to 30% respectively with 20% and 47% suspicious values since it is almost double of the values in range. By performing the Q test, the values were confirmed to be accpetable with regards to the actual value and values in the population, or rejected. Table 4.1 and 4.2 shows the values that were rejected and accepted for each data set. Notice that the 20% and 47% for % P and % P2O5 respectively, both belonging to Data Set 1 were rejected with 95% confidence level, meaning that the Qexp exceeded the value of the Qtabulated. Of all the trials in both Data Set 1 and 2, the group with values similar to that of the rejected values were the ones who obtained the greatest amount of precipitate. See Table 2. This rejection or errounous error in the data can be attributed to the determinate and indeterminate errors in the experiment. One more error that could be the reason for this rejection is the personal error in terms of the reading of the analytical balance. Also, because of this rejection in data, aside from the fact that Data Set 2 has lower number of population, Data Set 2 parameters for Measure of Precision are closer to each other, with the dried samples having greater values than that of the wet sample. Iti s because dried sample are purer than that of the wet sample containing still moisture and other interfering agent to getting the actual % P and % P2O5. V. Summary and Conclusions In this experiment, it was determined that the fertilizer sample has % P range of 6% to 13% with % P2O5 from 15% to 30%. However, the usual types of fertilizers with phosphates contain a minimum of 42.5 % water soluble phosphate and 46% total phosphate by weight, as in the case of Triple Superphosphate or 85 % water soluble and 20% available in Superphosphate. It should be noted that the theoretical values will vary depending on the type of fertilizer used in the experiment. Despite the data rejection that occurred, overall, it can be said that the experiment is a success since the objectives of the experiment such as performing gravimetric analysis in the determination of phosphorus content and to know the principle in separation by precipitation were achieved. Yet, it is recommended that there would be a specific manner of putting the precipitating agent, like addition dropwise or certain amounts per second or stirring so as to ensure the proper formation of crystals needed by the experiment. It should also be observed that upon digestion, or letting the mixture stand without agitation, the mixture should be covered to avoid impurities present in the atmosphere. VI.

Native Americans in the United States and James K. Polk Essay

6. Compare the expansionist foreign policies of Presidents Thomas Jefferson and James K. Polk. To what extent did their policies strengthen the United States? 1. President Thomas Jefferson a. Anti-Federalist: usually weary of American expansionism b. Louisiana Purchase i. After Spain gave New Orleans to the French, Jefferson sent Monroe to France to buy the strategic land for $2 million ii.

Top five job search tips for people over 65 - The Job Network

Top five job search tips for people over 65 - The Job Network Baby Boomers have driven the economy for decades. The youngest of the generation are just now turning 55 (a long-time â€Å"dream† age for early retirement), while much of the generation have already reached retirement age. In fact, there are approximately 10,000 Baby Boomers retiring every day. However, if you are among the many of this generation who plan to continue working, even beyond 65, there are few simple tips that can help you find a position right for you. 5 strategies to land your next job1. Boost your tech awarenessEvery generation becomes increasingly more tech savvy. While you may not be an â€Å"Insta Story† expert, or the ideal candidate for an organization’s social media guru, being up-to-date on the types of technology typically used in the workplace of the organization you’re applying for is important.If you’re embarking on a new field, take a course in a new computer software program. Even volunteering in your field of interest first can help you get a sense of what skillset is needed for the job. These actions can help communicate your willingness to learn and adapt to new work situations. Making sure you have the basics down can show you’ll be able to work alongside people who were raised on smartphones.2. Target your qualificationsMost Boomers will have a long work history, which translates to experience you can bring to a new position. However, you want to be able to target the key qualities and skillsets that are perfect for the open position you hope to get. Effectively, you’re not giving your interviewer a complete summary of your total work experience- or even highlighting the job you stayed in the longest. You want to give your interviewer a focus on specific experience that will help you perform the job. Connect the dots for them. This way, you help your interviewer sift through your long work history and show your true interest in the open position- and knowledge of its needed skil ls.3. Communicate your adaptabilityBeing overqualified can have its drawbacks. Hiring managers may assume you expect more money or assume you may already have a set way of doing things. Positioning yourself as flexible is key. While you may not be a blank slate that a new employer can help shape (or naà ¯ve about salary negotiations), you should highlight your willingness to find new ways of doing things and improving upon your tried-and-true practices.4. Be aware of generational differencesIf you’ve been working throughout your adult life, you’ve probably seen changes at work between the 20th and 21st century. Make sure your resume is updated both in new, current experiences and in the language you use to describe past work. While you don’t want to go overboard in the opposite direction in an attempt to appear more youthful, you should be prepared to deal with a younger generation in positions of power. While age and wisdom go together, you want to remain defe rential- especially to the hiring manager.5. Wow the interviewerAgeism in the workplace is real (and against the law) but even though this is the case, you may face assumptions from younger interviewers because you are an older candidate. You want to make sure you subvert these potential assumptions rather than play into them. For example, have all your facts and talking points ready and prepared, so you don’t appear â€Å"forgetful.† Convey enthusiasm for the position. Appearing to have â€Å"low energy† can count against older job candidates. Try simple things like using your smartphone in the interview to refer to notes- this simple action can communicate to the interviewer you are sufficiently tech-savvy.The fact is, you’re likely up-to-date on your references and your work skills- it’s just key that you prepare to convey them on interview day so there’s no doubt you’re up to any task that might come your way. Good luck!

Lab Report Example Finally the volumetric efficiency was found to be 60%. It is important to point out that the torque of the engine is dependent on the speed at which the engine turns and it is normally expressed in revolutions per minute (rpm). The curve of the power torque graph for the polo engine slopes smoothly and increases steadily as the revolutions per minute increase. The relationship of torque versus the engine is non linear. This relationship is provided as curve as shown on the torque curve. The exact shape and the height of the curve is specific for each engine type and this is normally determined by engine tests. The curve peaks at approximately 4000 rpm with a torque of about 90.3 N/M. The curves can be defined within the range of 1100-5500 rpm since that is the operating range of the polo engine. If the range is made lower than this, the engine is likely to stall while an increase would damage the engine. For energy balance to occur within the internal combustion engine, it is important that the total power generated by the brake power is kept at its peak. Energy performance is an indication of the degree at which the success of the internal combustion polo engine performs its assigned task. The total power is normally developed by the combustion of the fuel in the combustion chamber is greater than the brake power usually referred to as indicated power. This can be calculated as: The balance of the energy in the internal combustion engine will indicate that approximately 1/3 of the fuel energy that has been input is normally lost to the external environment through transfer of heat. There is also another 1/3 is available as the shaft performs its work. The heat losses must be decreased in order to improve the efficiency of the engine. 3. Exhaust smoke and other emissions: The oxides of nitrogen and any unburned carbons are an indication of the rate of efficiency of the engine. This parameter can be used

White Collar Crime as a Non-Violent Type of Crime Assignment

White Collar Crime as a Non-Violent Type of Crime - Assignment Example Owing to its organizational nature, white collar crime requires an organizational approach towards mitigation. The text in this study will define through a proposal addressed to a financial institution how a Chief Risk Officer can strategize and implement measures to curb white collar crime within a financial institution. The text will highlight a risk strategy, overall organizational chart, software and technology, and finally the procedures and policies that will see to it that the institution’s finances are safe and transparent. Every organization requires measures that address threats or potential risks which may act as loopholes leading to white collar crime within or beyond the organization. The offered consultative measures feature governance that is sustainable, programs that manage risks, and compliance with the set measures that work to manage, monitor, identify, and remediate the entire organizing process in preventing the vicious. Access means that all organizational documentation and data has controlled exposure to affect both its security and privacy. This is because access to such crucial aspects of an organization means that modification and/or misuse of the same can enable the one possessing them to exercise whatever they wish. The set access controls should be designed to ensure that the right person accesses the information or documentation they need, only when they need it. This is important because unauthorized personnel cannot misuse such, and in case of any crime, then it is possible to narrow down to the few who have the access (Pontell & Geis, 2010). Again, security should go beyond the organization level, especially in cases where there is internet use. Most firms store or conduct their activities online, where it is known that virtual transactions and storages are prone to cracking and hacking. As such, there should be measures that comply with up-to-standard IT security to curb these risks.  Ã‚
