Physics of sports Essay Example for Free

Physics of sports Essay Instructions: One of the best (and most fun) ways to explore physics and how it relates to the real-world is through sports. Every sport utilizes multiple physics principles. For this project you will chose a sport and study the physics principles involved. The sport you choose must be an actual sport, not a computer simulation or animation You will create a short PowerPoint presentation (5 slides max) summarizing your project. The following outline is designed to walk you though what you need to include in your project presentation. You will get more out of this project if you pick a sport you play or are interested in. And who knows, it may even improve your game! Project Outline: Be sure to include the following information in your presentation: Your name Sport Selected (include several illustrative images) Why did you choose this sport? List the physics principles that apply to your sport, and give specific examples of each. For example, all sports involve some sort of collision or impact. Thus the physics of momentum conservation and impulse apply. Include at least 3 relevant physics equations in your examples. Use a few images to illustrate your examples. Include at least 2 calculations in your presentation. To obtain data for your calculations you may (1) make measurements if possible, (2) make reasonable estimations, (3) do a bit of searching to find sample data. Be sure to explain how and/or where you obtained data for your calculations. All of your equations should be included in your PowerPoint presentation (not handwritten on board as you present). List the top athletes in your chosen sport. Identify what physical characteristics make them uniquely suited to your sport. Use physics to support your answer. Most sports have an upper limit on the possible athletic performance of the participants. This may be reflected by a world record or an obstacle of some sort. Discuss any such limitations in your sport and how physics may place such limitations on the athletes. For example, do you think it is physically possible for a sprinter to run 100 meters in under 9 seconds? What sort of trends do the world records suggest, and what physics principles apply? Upon completion email your presentation to Professor Brooks. Give your presentation a filename that includes your name and class in the following format: â€Å"John Doe phys1401. ppt† For examples of good past student projects you may download these SAMPLES.

Tolnaftate Drug Profile:

Tolnaftate Drug Profile: Trade Names: Tinactin Synonym: Tolnaftato, Tolnaftatum Structure: Fig: Structure of Tolnaftate Chemical Name: 0-2- naphthyl methyl (3- methyl phenyl thiocarbamate) Description: Tolnaftate is a synthetic thiocarbamate used as an anti- fungal agent that may be sold without medical prescription in most jurisdictions. It may come as a cream, powder, spray, or liquid aerosol, and is used to treat fungal conditions such as jock itch, athletes foot and ringworm. It is sold under several brand names in including Tinactin, odor Eaters, Absorbine, Aftate, Ting (85) . Molecular Weight: 307.41 g/mol Mechanism of Action: Tolnaftate is a topical fungicide. Though its exact mechanism unknown, it is believed to prevent Ergosterol biosynthesis by inhibiting squalene epoxidase (86) . It has also been reported to distort the hyphae and to stunt mycelia growth in susceptible organisms (87) . Melting Point: 110- 111.50C (230- 2330F) Pharmacological Action: Tolnaftate, a pharmacologically inert new fungicide for topical treatment of superficial mycoses, has been reported to be highly effective in skin infections caused by common pathogenic fungi as well as being non- irritating and non- sensitizing. It is a fungicidal invitro. During clinical investigation, studies showed no changes in the blood and urine of patients given tolnaftate topically, suggesting that the drug is not toxic to the kidney or the hematopoietic system. Distorts hyphae and inhibits mycelia growth in susceptible fungi. The anti- dermatophyte agent to tolnaftate was compared with the allylamine anti-fungal compounds naftifine and terbinafine. Tolnaftate was shown to inhibit sterol biosynthesis at the level squalene epoxidation and squalene was shown to accumulate in dermatophytes grown in its presence. Biochemical studies in whole and broken cells supported this conclusion and showed that the compound was active against squalene epoxidation in broken candida albicans cells, but was mwch less potent against whole cells. These results suggested there was a barrier to penetration in these yeasts (88) . Side Effects: Irritation Pruritus Contact dermatitis Onset: 24- 72 Hours Dosage: Topical/ cutaneous: Superficial dermatophyte infections, pityriasis versicolor. Adult: Apply a 1% gel / solution /powder /cream bid for 2-6 weeks; repeat if necessary. Continue treatment for 2 weeks after disappearance of all symptoms to prevent recurrence of infection.

Structure Where red – choline and phosphate group; black glycerol; green-unsaturated fatty acid; Blue saturated fatty acid. Chemical name 1,2-diacyl-sn-glycero-3-phosphatidylcholine Molecular weight 789 g/mol Description Lecithin occurs light yellow to dark brown, transparent or translucent, viscous liquid substance, as white to brown powder or granules, or as a light yellow to dark brown lump, having a slight, characteristic odour and taste. Identification: (1) Place 1 g of lecithin into a kjeldahl flask, add 5 gm of powdered potassium sulphate and 0.5 gm of cupric sulfate, and 20 ml of sulfuric acid. Tilt the flask at about 45ËÅ ¡C angle, heat gently until the effervesense , and raise the temperature to boiling. After the contents become blue, transparent solution, heat for 1-2 hours, cool and add an equal volume of water. Take 5 ml of this solution, and add 10 ml of ammonium molybdate solution (1 → 5), and heat. A yellow precipitate is formed. (2) To 0.5 g of lecithin, add 5 ml of diluted hydrochloric acid(1→2), heat in a water bath for 2 hours and filter. Use this solution is considered as a test solution. Perform paper chromatography with 10 Â µl of the test solution, using choline chloride solution (1 →200) as the control solution and a mixture of n-butanol, water, and acetic acid (4:2:1) as the developing solvent. A red orange spot is obtained from the control solution is observed. In pap er chromatography for the filter paper, use a No. 2 filter paper. Stop the development when the developing solvent rises about 25 cm, air-dry, spray with Dragendorffs reagent to develop a colour, and observe in daylight (90) . Solubility Insoluble in cold water and also acetone. Soluble in about 12 parts of absolute alcohol. Soluble in chloroform, petroleum ether, mineral oil and fatty acids. Sparingly soluble in benzene. Insoluble in cold vegetable oils and animal oils (91) . Viscosity Viscosity of lecithin is directly influenced by heat. Lower temperature equals higher viscosity and vise versa. The influence of temperature on lecithin viscosity is curvilinear, meaning that at low temperatures, a small increase in heat causes a elatively larger decrease in viscosity. For example, a lecithin with a viscosity of 10,000 centipoise at 24 0C, might have a viscosity of 5000 centipoise at 350C. An increase in temperature to 460C might lower the viscosity to 3000 centipoise and further increase to 570C would reduce viscosity to 2250 centipoise. Mixing oil, such as soybean oil or fish oil, with the lecithin at a rate of 20 % oil and 80 % lecithin as a similar influence on viscosity as raising temperature by 110C. In other words, a standard fluid lecithin with 10,000 centipoise viscosity when mixed with 20 % soybean oil would have an approximate viscosity of 5000 centipoise (92) TYPICAL PROPERTIES Acidity/alkalinity pH = 5.5–8.0 for a 1 % w/w aqueous solution Ash 1.5–3.0 %, depending upon the grade and viscosity Auto ignition temperature 360Â ºC Density (bulk) 0.341 g/cm3 Density (tapped) 0.557 g/cm3 Density (true) 1.326 g/cm3 Specific gravity 1.26 Melting point Browns at 190–200 Â ºC. Chars at 225–230 Â ºC. Glass transition temperature is 170–180 Â ºC. Iodine number 95-100 for liquid lecithin. 82-88 for powdered lecithin. Saponification number 196 Functional Category Lecithin is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues, and in egg yolk. It is naturally composed of phosphoric acid, choline, fatty acids, glycerol, glycolipids, triglycerides, and phospholipids. It is often used as an emulsifying agent.Available in variety of forms including granules, soft gels and chewable tablets. Applications: Lecithins are used in a wide variety of pharmaceutical applications. They are also used in cosmetics and food products. Lecithins are mainly used in pharmaceutical products as dispersing, emulsifying, and stabilizing agents, and are included in intramuscular and intravenous injections, parenteral nutrition formulations, and topical products such as creams and ointments. Lecithins are also used in suppository bases to reduce the brittleness of suppositories, and have been investigated for their absorption-enhancing properties in an intranasal insulin formulation. Lecithins are also commonly used as a component of enteral and parenteral nutrition formulations. There is evidence that phosphatidylcholine (a major component of lecithin) is important as a nutritional supplement to fetal and infant development. Furthermore, choline is a required component of FDA-approved infant formulas. Other studies have indicated that lecithin can protect against alcohol cirrhosis of the liver, lower serum cholesterol levels, and improve mental and physical performance. Liposomes in which lecithin is included as a component of the bilayer have been used to encapsulate drug substances; their potential as novel delivery systems has been investigated.This application generally requires purified lecithins combined in specific proportions. Therapeutically, lecithin and derivatives have been used as a pulmonary surfactant in the treatment of neonatal respiratory distress syndrome.mnb Stability and storage conditions: Lecithins decompose at extreme pH. They are also hygroscopic and subject to microbial degradation. When heated, lecithins oxidize, darken, and decompose. Temperatures of 160–1808C will cause degradation within 24 hours. Fluid or waxy lecithin grades should be stored at room temperature or above; temperatures below 108C may cause separation. All lecithin grades should be stored in well-closed containers protected from light and oxidation. Purified solid lecithins should be stored in tightly closed containers at subfreezing temperatures Incompatibilities Incompatible with esterases owing to hydrolysis. Safety Lecithin is a component of cell membranes and is therefore consumed as a normal part of the diet. Although excessive consumption may be harmful, it is highly biocompatible and oral doses of up to 80 g daily have been used therapeutically in the treatment of tardive dyskinesia.(8) When used in topical formulations,lecithin is generally regarded as a nonirritant and nonsensitizing material.(2) The Cosmetic Ingredients Review Expert Panel (CIR) has reviewed lecithin and issued a tentative report revising the safe concentration of the material from 1.95% to 15.0% in rinse-off and leave-in products. They note, however, that there are insufficient data to rule on products that are likely to be inhaled Handling precautions Lecithins may be irritant to the eyes; eye protection and gloves are recommended.

Solubility: Sorbitan esters are generally soluble or dispersible in oils; they are also soluble in most organic solvents. In water, although insoluble, they are generally dispersible. Viscosity Typical viscosity values for span80 1200-2000 mPa.s measured at 20Â ºC Typical properties HLB value : 4.3 Density : 1.01g/cm3 Saponification value : 149-160 Functional category: Emulsifying agent, non ionic surfactant, solubilizing agent, wetting, dispersing and suspending agent. Applications A non-ionic surfactant that can be used to form oil-in-water emulsions and in combination with low HLB surfactants can form water-in-oil emulsions. EPA approved oil spill dispersant. Sorbitan monoesters are a series of mixtures of partial esters of sorbitol and its mono- and dianhydrides with fatty acids. Sorbitan diesters are a series of mixtures of partial esters of sorbitol and its monoanhydride with fatty acids. Sorbitan esters are widely used in cosmetics, food products, and pharmaceutical formulations as lipophilic nonionic surfactants. They are mainly used in pharmaceutical formulations as emulsifying agents in the preparation of creams, emulsions, and ointments for topical application. When used alone, sorbitan esters produce stable water-in-oil emulsions and microemulsions but are frequently used in combination with varying proportions of a polysorbate to produce water-in-oil or oil-in-water emulsions or creams of varying consistencies. Sorbitan monolaurate, sorbitan monopalmitate and sorbitan trioleate have also been used at concentrations of 0.01–0.05% w/v in the preparation of an emulsion for intramuscular administration. Stability and storage conditions: Gradual soap formation occurs with strong acids or bases. Sorbitan esters are stable in weak acids or bases. Sorbitan esters should be stored in a well-closed container in a cool, dry place. Safety Sorbitan esters are widely used in cosmetics, food products, and oral and topical pharmaceutical formulations and are generally regarded as nontoxic and nonirritant materials. However, there have been occasional reports of hypersensitive skin reactions following the topical application of products containing sorbitan esters. When heated to decomposition, the sorbitan esters emit acrid smoke and irritating fumes. The WHO has set an estimated acceptable daily intake of sorbitan monopalmitate, monostearate and tristearate and of sorbitan monolaurate and monooleate at up to 25 mg/kg body-weight calculated as total sorbitan esters. Regulatory status Certain sorbitan esters are accepted as food additives in the UK. Sorbitan esters are included in the FDA Inactive Ingredients Guide (inhalations; IM injections; ophthalmic, oral, topical and vaginal preparations). Sorbitan esters are used in nonparenteral medicines licensed in the UK. Sorbitan esters are included in the Canadian List of Acceptable Non-medicinal Ingredients. 3.2.3 TWEEN 80: Non-proprietary names: Polysorbate 80 Synonyms: Atlas E; Armotan PMO 20; Capmul POE-O; Cremophor PS 80; Crillet 4; Crillet 50; Drewmulse POE-SMO; Drewpone 80K; Durfax 80; Durfax 80K; E433; Emrite 6120; Emulgin SMO; Glycospere O-20; Hodag PSMO-20; Liposorb O-20; Liposorb O-20K; Montanox 80; Polyoxyethylene 20 oleate; Protasorb o- 20; Ritabate 80;(Z)-sorbitan mono -9-octadecenoate poly(oxy1,2- ethanediyl) derivatives; Tego SMO 80; Tego SMO 80V; Tween 80.

Typical Properties: HLB value: 15 Density: 1.08 g/ml at 20 ËÅ ¡c Saponification value: 45-55 P H 5% aq solution : 5.5-7.5 Specific gravity (20/20ËÅ ¡c) : 1.065-1.095 Moisture content: Moisture content not more than 3% Solubility: Soluble in water and also soluble in ethanol. Insoluble in mineral oils. Viscosity (dynamic): The viscosity of tween 80 is 300-500 centi stokes at 25ËÅ ¡c Applications of tween80 in pharmaceutical formulation or technology: Polyoxyethylene sorbiton fatty acid esters (polysorbates) are a series of partial fatty acid esters of sorbitol and its anhydrides copolymerized with approximately 20, 5 or 4 moles of ethylene oxide per each mole of sorbitol and also sorbitol anhydrides. The resulting product is therefore a mixture of molecules of varying sizes rather than in single uniform compound. Polysorbates containing 20 units of oxy ethylene are hydrophilic nonionic surfactants that are used widely as emulsifying agent in the preparation of stable oil-in-water pharmaceutical emulsions. They may also be used as solubilizing agent for a variety of substances including essential oils and also other oils like oils are soluble vitamins, and teen 80 as a wetting agent in the formulation of oral and parenteral suspensions. They also have been useful in improving the oral bioavailability of drug molecule that are substrates for P-glycoprotein. Polysorbates are also used in cosmetics and also food products. Stability and storage conditions: Polysorbates are stable to electrolytes and week acids and bases; gradual saponification occurs with strong acids and strong bases. This type of oleic acid esters are sensitive to oxidation. Polysorbates are hygroscopic and should be examined necessary for water content before to use and dried if necessary. Prolonged storage of tween 80 along with other polyoxyethylene surfactants can leads to the formation of peroxides. Polysorbates should be stored in a well closed containers, protected from the light, in a cool and dry place. Incompatabilities: Discoloration and /or precipitation occur with various substances especially phenols, tannins, tars, tar like materials.The anti microbial activity of paraben preservatives is reduced in the presense of polysorbates. Regulatory status: Polysorbate60, 65and 80 are GRAS listed. Polysorbates 20, 40, 60, 65and 80 are accepted as food additives in Europe. Polysorbates 20, 40, 60, 65and 80 are included in the FDA inactive ingredients guide (IM,IV,oral,rectal,topical and vaginal preparations). Polysorbates are included in parenteral and non parenteral medicines licensed in the UK. Polysorbate such as 20, 21, 40, 60, 61, 65, 80, 81, 85 and 120 are included in the Canadian list of acceptable non medicinal ingredient.

Stress And Well Being Psychology Essay

Stress And Well Being Psychology Essay People act in different ways in stressful situations, some can cope with stressful situation and some cannot cope. People are more stressed today than in the past. Researches were made to measure and to manage stress. For measuring stress, researches used a couple of types. One was the Social Readjustment rating scale or SRRS. This measure of stress was devised by Holmes and Rahe in 1960. Their thought was that stress is more about the need of readjustment and change. For their research, they gathered almost 400 Americans and listed a scale of life events that could affect an individual. In their opinion, life changes have a major impact on an individual. In this scale at the top was death of a spouse with 100 units of life changes and the rest were adjusted accordingly. Almost 300 or even more of life changes units were linked to higher psychological and physical illnesses. Applying this method to measure stress, leads to some weakness and strengths, in which, the strength will be that it does capture something about stress, as SRRS were proven to be related to illnesses. A weakness could be that a particular life event like an operation for a person who has a life threatening illness is more str essful than a person operation for esthetical enhancement who just want to change something.(handouts, 12.11.2012) Questionnaires measures is another type of stress measuring like SRRS, the Type A personality, Hassles and Uplifts, etc. With questionnaire method is more easy to measure stress because they are quick and easy to administrate, but the weakness is that people may not be sincere when they answer. Some people could give answers in a way that will make them look good (social desirability bias). There are also job strain questionnaire based on job demands. Workers facing high psychological workloads demands and pressure, who work very fast, very hard and do not have enough time to finish their job, are in a greater risk for mental and physical illness.(handouts, 12.11.2012) Another type of stress measuring is controlled observation. There are various ways to measure, some of them cruel for example electric shocks, overcrowding, extremes of heat and colds used as stressors and others methods, by permanent interrupting the subjects during tests. A lot of researches were made on a link between Type A personality and heart diseases. The ones who developed the idea of Type A personality were Friedman and Rosenman. They had a different style to measure this Type A. They were given tests to people and then they constantly interrupt them during testing. They could observe that some of the participants dealt well with interruptions but some were more stressed because of the constant interruptions.(handouts, 12.11.2012) While measuring stress, researchers came up with some methods of stress management. They grouped up this stress management methods in two, one psychological method in which are hardiness training and stress inoculation training and the other is the physiological method containing drugs and biofeedback techniques. (Gross, R., psychology, 5th edition, 2005) Suzanne Kobasas Hardiness Training has the three major Cs: Control, Commitment and Challenge. The people with hardiness personality are more in control of their lives, they can manage better stressful situation and see difficulties as a challenge rather than a problem. Thats why Hardy personality is stress-resistant. The training for this has three stages. The first one is focusing, in which the client is thought to be able to recognise the biological signs of stress such as increase of heart rate, muscle tension and also to be able to identify the source for this stress. The second stage consists in reliving stress encounters, in which the clients relive their stress encounters and are helped in analysing those situations and their response to them. This method could give them some insight on coping strategies. The last one, self-improvement, involves learning of new techniques for the increase of the three Cs.(psychology AS, 2012/handout, 22.10.2012) Stress Inoculation Training or SIT is aiming to change peoples behaviour and thinking and is a cognitive behavioural therapy being specifically developed to deal with stress. There are also three stages as in Hardiness. The first stage is Conceptualisation phase, in which a relation is established between client and the therapist and the client is educated about the impact and nature of stress. The client is trained to be able to identify the stressors and to learn how to breaks them down into chunks that can be tackled. The second phase is Skills acquisition. Here the person will develop skills in constructive thinking. First the skills are taught and practised in the clinic and after that they can be gradually rehearsed in real life. The skills can include positive thinking, relaxation, social skills, etc. The last phase Application and follow-through, in which clients are given opportunities to apply in real life the coping skills learned, some could be ask to even train others as well.(psychology AS, 2012/handout, 22.10.2012) The Hardiness Training and the Stress Inoculation Training are both psychological methods. The next method is physiological which consist in Drugs intake as a method of stress management. There are a lot various types of tranquiliser and anti-anxiety drugs. The most common are benzodiazepines or Bz shortened. These include Librium, Ativan and Valium. The effect of this drugs is to lower the level of serotonin activity in the brain. If the level of serotonin is too low, produce depression but if it is too high produce anxiety. In 1960 they were highly prescribed as a replacement for barbiturates. Another group of tranquiliser are beta-blockers. Their activity is that of reducing the activation of the sympathetic branch of the anatomic nervous system meaning the activity reduction of SAM axis. The drugs are fast effective but the problem is that they are highly addictive.(handout, 29.10.2012) Based on the evaluations of the methods, there can be found a lot of weaknesses and strengths in each and every one of them as well as similarities and differences between them. In Hardiness Training strengths are that is it working, it deals with the cause of stress not just the symptoms, are more effective to people. The weaknesses consists in focusing on middle-class business people, some people find control stressful-they dont like to be in control, people respond in different ways to Hardiness Training, some people doubt about the all three Cs being equally important in protection against stress and even though control is important the commitment and challenges have no effects. (hand out, 22.10.2012 / psychology AS, 2012) SIT works well in general and also works for acute and conic stress. The weaknesses of SIT consists in it being time consuming, requiring high motivation and in the fact that not all people need the same skills to cope with stress. (hand out, 22.10. 2012 / psychology AS, 2012) Drugs work in reducing anxiety also BZ are better than placebo effect, drugs are easy to use involving only the need to actually take the pill and for some forms of phobias are quite handy. Weaknesses are the fact that some drugs are highly addictive, produce strong withdrawal symptoms, patients develop tolerance to them quickly, effectiveness requires a higher dosage, they have a limit of recommended intakes of a maximum of four weeks, treats the symptoms not the actual cause of stress, does not sort out the problem and because of dependency of drugs some people become like vegetables. ( hand out, 29.10. 2012 / psychology AS, 2012) The similarities between these types are: all of the methods allows the person to be in a better frame of mind to deal with stress; both SIT and Hardiness Training involves motivation and they take place over weeks and treat the cause rather than the symptoms and both change the way people think and help people learn skills to deal with their stress. The differences between these types are: The effects of the drugs are relatively instant while the effects of SIT and HT require a longer period of time and greater effort until the results are seen; Drugs can be addictive and have short term solutions but other methods like HT may deal with the real issue; people can develop tolerance to drugs in comparison with the other methods that are more constant; drugs have side effects, the other methods dont; no withdrawal effect from stopping SIT and HT like there is with drugs; HT depends on the liking for control but drugs dont.

Neil Simon, The Most Successful Playwright In The History Of Theatre :: essays research papers fc

Neil Simon, the Most Successful Playwright in The History of Theatre "It can be argued that Neil Simon is not only America's most successful playwright, but also the most successful playwright in the history of theatre."1 Despite being criticized for lack of substance, his hugely successful comedies are consistently revived, whether on Broadway or in other community or dinner theatres. Last week the University of Notre Dame's Mainstage season opened with the departmental premiere of Barefoot in the Park. Though the play originally opened more then thirty years ago, the themes of compatibility and compromise that it presents are still relevant today. Simon masterfully manipulated the plot of Barefoot in the Park to include all of the elements of a fine play (intrigue, credibility, surprise, etc.) and to create a viable playscript that both emphasizes the play's major themes and, just as importantly, makes the audience laugh. Simon has skillfully constructed the plot of Barefoot in the Park to showcase and emphasize his themes of compatibility and need for compromise. The plot itself starts out fairly simple. In the first act, Paul and Corie Bratter, wed but six days, move into their new apartment on the top floor of a brownstone in New York City. From the very first, the audience can see that these are two very different characters that have very different values, and yet Paul and Corie are very much in love. The plot progresses as other characters are introduced. First to visit the newlyweds is Corie's mother, Mrs. Banks. The relationship between Corie and her mother also involves a clash of very distinct personalities. With the appearance of the Bratter's eccentric upstairs neighbor, Victor Velasco, Corie sees the opportunity to play matchmaker and inject a little romance into her staid mother's life. The first act concludes with Corie's plan to bring the two together at an upcoming dinner party, much to the chagrin of her husband Paul. This creates intrigue--"that quality of a play which makes us curious (sometimes fervently so) to see 'what happens next'"2-- because the audience is left wondering whether Corie's plan will work. Thus the first act provides exposition, creates a feeling of suspense, and begins to showcase the compatibility problems in the relationships of several of the characters. The second act takes place in two parts: the first before Corie's dinner party, and the second in the aftermath. Throughout the first part of the act, Simon emphasizes the enthusiasm, spontaneity, and lack of forethought with which Corie approaches her matchmaking task. Paul, on the other hand, acts like "a stuffed shirt"3 and tries to show Corie the foolishness of her plan.

Illegal Immigrants and the Educational System Essay -- Argumentative P

Illegal Immigrants and the Educational System Secondary education is a highly debated subject. Many critics of secondary education say that inner-city high schools and students are not receiving the same attention as students from non inner-city high schools. Two of the biggest concerns are the lack of school funding that inner-city high schools are receive and the low success rate in sending inner-city high schools graduates to college. Critics say that while inner-city high schools struggle to pay its teachers and educate its student’s non inner-city high schools don’t have to deal with the lack of school funding. Also students from non inner-city high school are not being given the opportunity to attend colleges once the students graduate. But opponents of these critics blame an entirely different issue; and that is illegal immigrant students over crowding and attending high school at the expense of taxpayers. It cost millions of dollars a year for illegal immigrant students to attend high school and th is is the main reason why schools are experiencing budget problems. Teaching illegal immigrant students creates a difficult learning environment and that is why students in inner-city high schools are not moving on to a higher education. This paper will explore the controversy and issues of secondary education; it will expose the hidden truths and prove that illegal immigrants are taking a toll on the education system. So why has this become a problem that has grown way out of proportion? An organization known as Federation for American Immigration Reform (FAIR) published a report on Immigration and School Overcrowding, with the help of David W.

The Court could reverse the ruling if these circumstances were to change or if Congress were to make the exclusion of these students explicit by legislation. Source: U.S. Supreme Court: Plyler v.

Mercantilist Relationship Between the American Colonies and the British Government Essay

Mercantilism is an economic policy and theory where the government has complete control of trade, both foreign and inside boundaries. This policy was dominant during the 16th, 17th, and late 18th centuries, it demanded a positive balance of trade between the countries it was involved with. There were many policies that were within the theory based upon mercantilism including, building a network of overseas colonies and forbidding them to trade with other nations, forbidding trade to be carried in foreign ships, export as a trade barrier using domestic goods and services competitive against imports, and restricting domestic consumption with non-tariff barriers to trade. The British government established a mercantilist relationship with the American colonies that was to its benefit until 1763 and then the relationship no longer was of economic benefit to the British crown. Prior to 1763 the colonists had no choice but to go along with Parliament’s right to take actions on their behalf and the predominance of Britain’s economic benefits over their personal ones. Seven Years’ War was the war that altered the parliaments actions, had been intended to regulate trade and nothing else, Parliament’s arrangements began to conflict with the colonists’ interests. This caused the colonies to grow and thrive, by the time the British realized this Americans had already established lucrative trade with other countries. Britain became more aware of this growing â€Å"problem† and began to keep a close eye on the colonies and implemented regulatory policies, the British instituted a series of laws of trade and navigation known as the Navigation Acts. The purposes of these acts were to limit colonial trade to the British only. For this to be accomplished all trading to be done involving the colonists was to be on either English vessels or colonial-built vessels, therefore, if colonists planned to trade with other nations all of their goods had to first be shipped to England. This gave the British the chance to get a hand on the items being traded and to collect revenue from taxation before the products were traded. Another limitation that was set on the colonies was that in order to trade products such as tobacco, sugar, and cotton it had to be done with the British only. When the British would notice the colonies beginning to make profit they would add the product that was causing the increase in revenue to the list of products only to be traded with them. Although there were many restrictions placed upon the colonies, they did not cause as much damage as Britain may have hoped. Benjamin Franklin answered when asked, â€Å"I have never heard any objection to the right of laying duties to regulate commerce; but a right to lay internal taxes was never supposed to be in Parliament, as we are not represented there†. There were even some benefits even to having these regulations, such as a built in market for raw products that they had and the British did not rigidly enforce the trading regulations that were set. Following Great Britain’s achievement of French territory in North America after the end of the French and Indian War allotted the Proclamation of 1763 in October of 1763. The purpose of the proclamation was to establish Britain’s new North American Empire and to stabilize associations with Native North Americans through regulation of settlement, trade, and land purchases. The proclamation kept certain lands for the Indians and prevented the colonies from settling inland. The colonies wished to expand their territory inlands but with the Proclamation of 1763 they were unable to do so, causing massive amounts of interest conflicts. The British seemed to be enforcing this proclamation more so than any other laws placed on the colonies before. Troops were stationed along the frontier to give the colonists’ no control over attempting to expand their population inland. The colonies feared for overpopulation and crowded cities along the coastline. It appeared that the break down of this mercantilist relationship between the United States colonies and Britain along with the split of America from the British Empire was unavoidable. Before the French and Indian war, Britain was having a hard time keeping up with and maintaining regulations that they had placed upon the colonies. The trade laws were inadequately implemented and the colonies were able to go about their own political and economic systems independently. But, with the close of the war Parliament concluded the time of this neglect of enforcement and became more dominate with the colonies in order to reestablish complete control over their trade. Pervious laws that were established to benefit Britain were enforced harshly and new laws were also applied to further benefit the British. This led to animosity between Britain and the colonies because the colonies experienced economic independence for too long a period causing the colonists to have no desire to return to how things used to be. The aggressive application of the Navigation Act to the colonists subdued their manufacturing operations and increased resentment against the British Parliamentary. The severe enforcement of these laws led to inflation and alienation in the colonies, neither of which benefited the British Empire. During this time of strict enforcement there were many more laws and acts placed upon the colonies to restrict their trade and growth. Parliament passed the Sugar and Molasses Act trying to bring the colonies in line with regard to payment of taxes. The Sugar Act reduced the rate of tax on molasses and listed more foreign goods to be taxed including coffee, wines, sugar, and various other goods. The tax on caused the instantaneous deterioration in the rum industry in the colonies. This interrupted the economy in the colonies because it reduced the markets to which the colonies could sell and the amount of currency available to them for the purchase of British manufactured goods. This act, and the Currency Act, set the stage for the revolt at the imposition of the Stamp Act. The Stamp Act of 1765 was a direct tax on documents and articles, this act directly affected all colonists. The law required a stamp to be placed on all printed materials, including legal documents, almanacs, pamphlets, and newspapers. Although this affected all colonists, lawyers, clergymen, and printers felt the wrath of this act the most. Benjamin Franklin stated â€Å"There is not gold and silver enough in the colonies to pay the stamp duty for one year†. The before and after of this act set in stone the perceived idea that the mercantilist benefits of the relationship between the colonies and Britain may have run its course. After debate about the collection of taxes due to the Stamp Act was the Quartering Act of 1765. The Quartering Act was part of the intolerable acts; the purpose of this act was only to take back hold of the colonies. The act violated the Bill of Rights, which forbids taxation without representation and the raising or keeping of a standing army without the consent of Parliament; colonies disputed the legality of this Act. In his first speeches in Parliament, Camden said, â€Å"taxation and representation are inseparable; this position is founded on the laws of nature; it is more, it is itself an eternal law of nature; for whatever is a man’s own, is absolutely his own; no man has a right to take it from him without his consent, either expressed by himself or representative; whoever attempts to do it, attempts an injury; whoever does it, commits a robbery; he throws down and destroys the distinction between liberty and slavery. Taxation and representation are coeval with and essential to the constitution†¦Ã¢â‚¬  If the soldiers outnumbered the housing available the colonies were expected to pay the cost of housing and feeding the troop, after the arrival of the troops New York refused to pay for supplies causing the troops to have to stay aboard their ships. Even after attempts to revise the Stamp Act, New York still resisted which led to the repeal of this act and the Stamp Act. With no doubt it seemed that violent hostility would prevail even with any effort to change the Acts making it almost impossible for Britain to establish any hope for a beneficial relationship with the colonies. The steady resistance to the Stamp Act led to it being repealed, which cost the British, â€Å"Suppose a military force sent into America; they will find nobody in arms; what are they then to do? They cannot force a man to take stamps who chooses to do without them. They will not find a rebellion; they may indeed make one. † This repeal showed the colonists that their resisting the act worked and would put fire to their future revolts considering this worked for them. The British were losing money now and the colonies did not seem to be hurt as badly as would have been hoped by the British. To down play the win that the colonies had just accomplished Parliament set out another act, the Declaratory Act, to serve as a punishment. The Declaratory Act asserted that Parliament â€Å"had, hath, and of right ought to have, full power and authority to make laws and statutes of sufficient force and validity to bind the colonies and people of America †¦ in all cases whatsoever†. In the context and the word choice in which this was written shows that the act was intentionally clear-cut and to the point. Parliament had the upper hand and the absolute power to make laws and changes to the colonial government, â€Å"in all cases whatsoever†. Caught up in attempting to strip the colonies of their freedoms in order to prevent them from creating a profit, the British were losing money and quite frankly, running out of it. In one final attempt to gain back control of the colonies and make their relationship work Parliament passed the Townshend Act. A colonist identified as Brutus argued against that assumption, stating, â€Å"Nothing can be more flagrantly wrong than the Assertion of some of our mercantile Dons. John Hancock adds, â€Å"Taxes equally detrimental to the commercial interests of the Parent country and the colonies are imposed upon the People, without their consent; Taxes designed for the Support of the Civil Government in the Colonies, in a Manner clearly unconstitutional, and contrary to that, in which ’till of late, Government has been supported, by the free Gift of the People in the American Assemblies or Parliaments; as also for the Maintenance of a large Standing Army; not for the Defiance of the newly acquired Territories, but for the old Colonies, and in a Time of Peace. This testimony written in a letter was tremendously effective in the efforts to abolish this act placed upon the colonies; there were also the Letters from a Farmer in Pennsylvania, which had its influence on the topic as well. There were twelve letters that were widely read and reprinted throughout the thirteen colonies, and were a major factor in attempting to unit the colonists against the Townshend Acts. Dickenson, the farmer, acknowledged the great power that the Parliament had in concern for the whole British Empire but argued that the taxes that were given to the colonies were for purpose of their own personal gain in revenue rather then what was stated in the books of the acts being for purpose of trade only. Dickinson foresees the possibility of future conflict between the colonies and Great Britain, but urges against the use of violence, â€Å"If at length it becomes undoubted that an inveterate resolution is formed to annihilate the liberties of the governed, the English history affords frequent examples of resistance by force. What particular circumstances will in any future case justify such resistance can never be ascertained till they happen. Perhaps it may be allowable to say generally, that it never can be justifiable until the people are fully convinced that any further submission will be destructive to their happiness. † The colonies boycotted this idea, their boycott, although it failed, gave them the strength to continue to not follow the acts that the Parliament required of them. The British had no way to enforce the collection of taxes so Britain had no choice but to repeal the Townshend Act. Britain was completely unstable and given this, the mercantilist relationship was coming to an end between the United States colonies and the British; the Tea Act would create the breaking point for this relationship. â€Å"An act to allow a drawback of the duties of customs on the exportation of tea to any of his Majesty’s colonies or plantations in America; to increase the deposit on bohea tea to be sold at the India Company’s sales; and to empower the commissioners of the treasury to grant licenses to the East India Company to export tea duty-free. The Tea Act of 1773 caused in turn the Boston Tea Party, which aggravated the British so greatly that they delivered a punishment act. The punishment acts were called the Coercive Acts and also, along with other acts, became part of the intolerable acts the British had placed upon the colonies. The Boston Port Act, The Massachusetts Government Act, The Administration of Justice Act, The Quartering Act, and the Quebec Act were all placed in order for Britain to again attempt to take control over the colonies. The restrictions placed on the colonies by these acts included the closing of the port of Boston, limited the meetings to one meeting per year, allowed the governor to move trails, and attempted to house the British solders. This out lash of over bearing authority over the colonies became known as the main reason that the mercantilist relationship could not continue. Britain’s attempts of harsh leadership and the lack of economic opportunities became great enough to continuously push the colonies away and gave them reason to revolt and not comply. As years passed the interests of the colonies and British began to not be similar in any ways, causing conflicts. The colonists educated themselves in ways that the British had not expected, giving the colonies the upper hand in knowing what they deserved and what was being taken from them. There were no longer any benefits to having a relationship with Britain and the colonists were well educated on this fact and showed their feelings on this aspect in many ways. The mercantilist relationship was no longer making a profit for the British Crown or bringing benefits to anyone; it was causing them to lose money. This loss was apparent after the downfall of both the economic systems after the French and Indian War in 1763.

Poem Analsys

After reading The Eagle and Hawk Roosting, there were several differences and similarities that I noticed between them. Some of these brought them closer to each other while others made them more independent of each other. In both poems the main characters of the hawk and the eagle seem to be aware of their surroundings in a humanistic way. The Eagle, while being much shorter than Hawk Roosting, is still able to impart the feeling that he is the master of his domain.I think that Hawk Roosting, however, is able to give more relatable sensory details than The Eagle because of the perspective that it was told from. Because of the first person point of view in Hawk Roosting the author is also able to use personification to make himself seem more important. In The Eagle, a sense of importance is still present, but it can be overlooked because of the third person point of view. While only The Eagle uses rhyme, the rhythm in both poems helps to move the reader through it.They both have sens ory details for sight, but I think that Hawk Roosting uses the sense touch in a very personal way with the phrase â€Å"My feet are locked upon the rough bark. † While both poems impart a feeling of power and majesty, they convey different parting experiences for the reader. Hawk Roosting ends with the hawk believing that he is the master of everything. The Eagle, I believe, finishes with a sense dignity.
