Essay Lowering the Drinking Age to Eighteen - 1340 Words
In 1984 Transportation Secretary Elizabeth Dole lobbied for all states to raise the legal drinking age from eighteen to twenty-one. The consequence for a state not raising the age was to lose a portion of their federal highway funding. I personally believe that the drinking age being twenty-one is just like when the voting age was twenty-one, if I can go to war and die for my country, then I should be able to go to the bar and buy a beer. nbsp;nbsp;nbsp;nbsp;nbsp;One of the biggest problems in our society is under age drinking. They tell us how we arenââ¬â¢t allowed to drink, that we arenââ¬â¢t old enough or mature enough to do it, but the more adults talk about it, the more teenagers want to do it.

So they go out their first night, grab a cup, and start to drink. Sounds like fun until they try to walk home and they canââ¬â¢t remember where their dorm is. So they stumble around for a while, sometimes alone and other times with a group of friends. This goes on for a while until something finally happens. One outcome, the one that all kids think is going to happen, is that they finally find their limit and learn how to be responsible with their drinking while having fun at the same time. Another option is that they end up in jail for the night and then they have to go explain to mommy and daddy why they need an extra $200 this month. The next possible outcome is the one that no kid ever thinks will happen to them, that is when they end up in the hospital getting their stomach pumped because they drank too much. For most kids that is enough to make them never drink that much again, but some kids see it as a challenge, and the next time they go to the hospital it is because someone found them dead on the floor the next morning. My friends and I started to really drink the summer before my senior year.

Personal Experience Subjects in Which I Have Excelled Essay
The subjects I excel in are math and science. Every since I was adolescent, I have always had a keen sense of numbers. This undoubtedly helped a lot with the variety of science classes that utilize math skills. Science, though, is, without a doubt, the subject I excel in the most, and I have my extraordinary great-grandmother to thank for that. Around when I was eight, I found out my great-grandmother had cancer which was gradually making her health decline. Eventually the cancer had spread to her legs and within a time span of a year, she had become a double amputee.

In my mind, I knew this sudden dream to become an anesthesiologist was far-fetched, but, in my heart, I believed this was the key to helping my great-grandmother get better. Years later, now older and wiser, I realize the specifics of the career I have chosen and how it wonââ¬â¢t benefit my great-grandmother as much as I had hoped it would have. Even so, this life changing event has benefited me in numerous ways. Academically-wise, I have never received a grade lower than a B in any of my science classes throughout my high school career, and I am the president of the peer to peer Science tutoring club. I enjoy tutoring students about the different aspects of science that go unnoticed even though we utilize science everyday in our lives.

Education in ââ¬ÅThe Republicââ¬Â ââ¬ÅDiscourse on the Arts and Sciencesââ¬Â Free Essays
The role and significance of education with regard to political and social institutions is a subject that has interested political philosophers for millennia. In particular, the views of the ancient Greek philosopher Plato, as evidenced in The Republic, and of the pre-Romantic philosopher Jean Jacques Rousseau in his Discourse on the Arts and Sciences, present a striking juxtaposition of the two extremes of the ongoing philosophical and political debate over the function and value of education. In this paper, I will argue that Rousseauââ¬â¢s repudiation of education, while imperfect and offering no remedy to the ills it disparages, is superior inasmuch as it comes closer to the truth of things than does Platoââ¬â¢s idealized conceptions. We will write a custom essay sample on Education in ââ¬Å"The Republicâ⬠ââ¬Å"Discourse on the Arts and Sciencesâ⬠or any similar topic only for you Order Now To do so, I will first examine Platoââ¬â¢s interpretation of the role of education and its function in shaping the structure of society and government and in producing good citizens. I will then introduce Rousseauââ¬â¢s view of education and the negative effects of the civilized culture which it produces, and using this view, will attempt to illustrate the naivete and over-idealization of Platoââ¬â¢s notions. Finally, I will attempt to demonstrate that it is Rousseauââ¬â¢s view, rather than Platoââ¬â¢s, that is ultimately more significant in assessing the actual (vs. idealized) merits (or lack thereof, in Rousseauââ¬â¢s case) by which education should be judged with regard to the nurturance of good citizens. For Plato, the question of the role of education arises near the end of Book II (377e), after a discussion of both the necessary and consequent attributes of Socratesââ¬â¢ kallipolis or ââ¬Å"Ideal City. Such a city, Socrates argues, will, before long, have need of both a specialization of labor (in order for the greatest level of diversity and luxury of goods to be achieved) and of the establishment of a class of ââ¬Å"Guardiansâ⬠to protect the city from its envious neighbors and maintain order within its walls (i. e. , to police and govern the city). This, in turn, leads inexorably to the question of what attributes the Ideal City will require of its Guardians, and how best to foster such attributes. The early, childhood education of the Guardians, Socrates argues, is the key. What, then, asks Socrates, should children be taught, and when? This quickly leads to a discussion of censorship. Socrates cites a number of questionable passages from Homer which cannot, he thinks, be allowed in education, since they represent dishonorable behavior and encourage the fear of death. The dramatic form of much of this poetry is also suspect: it puts unworthy words into the mouths of gods heroes. Socrates suggests that what we would call ââ¬Å"direct quotationâ⬠must be strictly limited to morally-elevating speech. Nothing can be permitted that compromises the education of the young Guardians, as it is they who will one day rule and protect the city, and whom the lesser-constituted citizens of the polis will attempt to emulate, assimilating, via the imitative process of mimesis, to the Myth (or ââ¬Å"noble lieâ⬠) of the Ideal City in which justice is achieved when everyone assumes their proper role in society. The process of mimesis, is, of course, yet another form of education, in which those of Iron and Bronze natures are ââ¬Å"instructedâ⬠and inspired by the superior intelligence and character of the Gold and Silver members of the Guardian class. It is therefore a form of education without which the polis cannot operate. Thus, for Guardian and ordinary citizen alike, the education of the young and the continuing ââ¬Å"instructionâ⬠of the citizenry are crucial. In addition to these aspects, Plato also conceives of another function of education, and one which is quite significant in its relation to Rousseauââ¬â¢s views. For Plato, education and ethics are interdependent. To be ethical, in turn, requires a twofold movement: movement away from immersion in concrete affairs to thinking and vision of unchanging order and structures (such as justice) and then movement back from dialectic to participation and re-attachment in worldly affairs. It is a temptation to become an abstract scholar. But the vision of the good is the vision of what is good for oneself and the city ââ¬â of the common good. If one does not return to help his fellow human beings, he becomes selfish and in time will be less able to see what is good, what is best. An unselfish devotion to the good requires an unselfish devotion to the realization of this good in human affairs. Just as the purpose of understanding order and limits in oneââ¬â¢s own life is to bring about order and restraint in oneââ¬â¢s own character and desires, the understanding of justice requires application in the public sphere (through education). A man who forgets the polis is like a man who forgets he has a body. Plato thus advocates educating both the body and the city (for one needs both), not turning oneââ¬â¢s back on them. If education is, for Plato, the means by which man comes to fully realize (through society) his potential as a human being and by which society as a whole is in turn elevated, for Rousseau it is quite the opposite. Education, argues Rousseau, does not elevate the souls of men but rather corrodes them. The noble mimesis which lies at the heart of education in Platoââ¬â¢s kallipolis is for Rousseau merely a slavish imitation of the tired ideas of antiquity. The ill effects of this imitation are manifold. Firstly, argues Rousseau, when we devote ourselves to the learning of old ideas, we stifle our own creativity and originality. Where is there room for original thought, when, in our incessant efforts to impress one another with our erudition, we are constantly spouting the ideas of others? In a world devoid of originality, the mark of greatness, intelligence, and virtue is reduced to nothing more than our ability to please others by reciting the wisdom of the past. This emphasis on originality is in marked contrast with Plato, who finds no value in originality, deeming it antithetical to a polis otherwise unified by shared Myths of the Ideal City and of Metals. Rousseau rejects this ââ¬Å"unityâ⬠, rightly denouncing it as a form of slavery , in which humanityââ¬â¢s inherent capacity for spontaneous, original self-expression is replaced with the yoking. of the mind and the will to the ideas of others, who are often long dead. In addition to suppressing the innate human need for originality, education (and the appetite for ââ¬Å"cultureâ⬠and ââ¬Å"sophisticationâ⬠that it engenders) causes us to conceal ourselves, to mask our true natures, desires, and emotions. We become artificial and shallow, using our social amenities and our knowledge of literature, etc. , to present a pleasing but deceptive face to the world, a notion quite at odds with the ideas of Plato. We assume, in Rousseauââ¬â¢s words, ââ¬Å"the appearance of all virtues, without being in possession of one of them. Finally, argues Rousseau, rather than strengthening our minds and bodies and (a critical point) moving us towards that which is ethical, as Plato contends, education and civilization effeminate and weaken us physically and (perhaps most significantly) mentally, and cause us, in this weakness, to stoop to every manner of depravity and injustice against one another. ââ¬Å"External ornaments,â⬠writes Rousseau, ââ¬Å"are no less foreign to virtue, which is the strength and activity of the mind. The honest man is an athlete, who loves to wrestle stark naked; he scorns all those vile trappings, which prevent the exertion of his strength, and were, for the most part, invented only to conceal some deformity. â⬠Virtue, as opposed to Platoââ¬â¢s conception, is an action, and results not from the imitation inherent in mimesis, but rather in the activity ââ¬â in the exercise ââ¬â of the body, mind and soul. Education, however, demands imitation, demands a modeling upon what has been successful. How, then, do we rightly assess the merits of education with regard to its it molding of the public character ââ¬â in its ability to produce ââ¬Å"goodâ⬠citizens. The answer to this hinges, I submit, on how we choose to define the ââ¬Å"goodâ⬠citizen. Clearly, if obedience (or ââ¬Å"assimilation to a political ideologyâ⬠, or perhaps ââ¬Å"voluntary servitudeâ⬠) is the hallmark of the good citizen, then we must regard Platoââ¬â¢s disposition towards education as the proper one. However, obedience, despite its obvious centrality to the smooth operation of society (as we would have social chaos were it completely absent), has its useful limits. Over-assimilation to a political idea or ââ¬Å"blueprintâ⬠is every bit as dangerous ââ¬â indeed, far more so ââ¬â as the utter under-assimilation of anarchy. For those inclined to dispute this, I would urge them to review the history of Nazi Germany as perhaps the definitive example of what sad, awful spectacles of injustice we humans are capable of when we trade in our mental and spiritual autonomy for the convenient apathy and faceless anonymity of the political ideal. Furthermore, if , as Rousseau contends, our civilization is such that, ââ¬Å"Sincere friendship, real esteem, and perfect confidence [in each other] are banished from among men,â⬠what is the quality of the society for which education ââ¬â any modern education ââ¬â purports to prepares us? When, ââ¬Å"Jealousy, suspicion, fear coldness, reserve, hate, and fraud lie constantly concealed under â⬠¦ [a] uniform and deceitful veil of politeness,â⬠what is left to us to educate citizens for, other than the pleasure we seem to derive in pedantic displays of hoary knowledge? If we remove the civility from ââ¬Å"civilizationâ⬠, what remains to us that any education will remedy? How to cite Education in ââ¬Å"The Republicâ⬠ââ¬Å"Discourse on the Arts and Sciencesâ⬠, Papers

Introduction to Flood Routing Essays
Introduction to Flood Routing Essays Introduction to Flood Routing Paper Introduction to Flood Routing Paper The Muskingum flow routing method has been very well researched and established in the hydrological literature. Its modest data requirements make it attractive for practical use. The paper gives a general overview of the Flood routing concept and types, and then goes on to explain the Muskingum method in detail. Introduction to Flood Routing Flood routing is a technique which is used to determine the flow hydrograph characteristics like shape and movement along a water course, and how these are affected by various factors like system storage and system dynamics on the shape and movement of flow hydrographs along a watercourse. In other words Flood routing can be described as a process of calculating outflow rates, reservoir stage and storage volume from a stream channel once inflows and channel characteristics are known. The process of flood routing is used for the hydrologic analysis in flood forecasting, flood protection, reservoir design and spillway design etc. The principle of routing is used here for predicting the temporal and spatial distribution of hydrograph, during the course of its travel through the various sections of a stream (Subramanya 2002). Basic Principles of Routing All hydrologic routing methods use a common continuity equation as their common base. According to this equation, the difference between inflow and outflow rates is equal to the rate of change of storage. Mathematically the equation can be written as below: (Gosh 1997 p. 67) In the above equation, I is the rate of inflow, and at any time the corresponding outflow is O. dS is the storage that is accumulated during a very small duration of time dt. Figure below represents the pictorial relation between storage S and discharge Q: (Flood Routing) The above equation considers the losses due to seepage, evaporation and direct accretion to storage, as small enough to be ignored. The equation can be written in integral form as below: (Watson 1983 p. 490) Flood routing methods aim to solve the above one-dimensional mass continuity equation. Flood routing methods classification There are many flood routing methods available like using St. Venant equations, Level Pool Routing, Goodrich Method, Pulââ¬â¢s Method, Kinematic Routing, Muskingum equation, Muskingum-Cunge routing etc. These methods can be divided into the following two categories: Hydrological routing ââ¬â These methods mainly use the continuity equation Hydraulic routing ââ¬â These methods combine the equation of continuity with the equation of motion for unsteady flow. (Subramanya 2002 p. 271) Types of Flood Routing In all the hydrologic analysis applications mentioned above, two categories of routing can be clearly recognised: Reservoir routing ââ¬â In this type of routing, the effect of a flood wave entering a reservoir is studied. This is done by determining the volume-elevation characteristic of a reservoir in addition to the outflow-elevation characteristic of the spillway and also other outlet structures present in the reservoirs (Chadwick Morfett 1986 p318). The results are used to predict the variation of reservoir elevation and outflow discharge with respect to time. This type of routing is necessary for: Designing the capacity of the spillway and other outlet structures Determining the correct location and size of capacity of the reservoir pertaining to a particular requirement condition. Channel routing ââ¬â In this type of routing, a study is made of the change in shape of a hydrograph as it travels down a channel. This done by considering a channel reach i. e. the specific length of the stream channel, and an input hydrograph at the upstream end of the stream. The results are used to predict the flood hydrograph at various sections of the reach (Chadwick Morfett 1986 p. 322). The output data obtained using this method is, the information on the flood-peak attenuation and, the total duration of the high-water levels. This type of routing is considered very important for: Flood-forecasting operations Flood-protection related work Hydrologic Channel Routing In case of reservoir routing, the storage is a function of output discharge, whereas in case of channel routing, the storage is a function of both inflow and outflow discharges. This is the main reason why entirely different routing methods are needed for Channel routing. When a river is in flood, the flow can be characterized as gradually varied unsteady flow. In a particular channel reach the water surface as expected is not parallel to the channel both. Additionally it also varies with time. At the time of flood, the total volume in storage can be divided into two categories: Prism storage ââ¬â This is defined as the volume that would exist in case there is uniform flow at the downstream depth. i. e. Prism storage = Wedge storage ââ¬â This term represents the wedge-like volume which is formed between the actual water surface profile and the prism storage surface i. e. Wedge storage = In the downstream section of a river reach, the prism storage is observed to be constant, when the depth is fixed. However, the wedge storage changes from positive to negative depending on the type of flood. The wedge storage is positive at the time of advancing flood, while it is negative in case of a receding flood. (Subramanya 2002 p. 282-283) (Flow Routing 2) .Muskingum Method Introduction Flood routing in open channels can be determined using a variety of modeling procedures. These methods follow a wide range of methodologies, which can be categorized as: Simple like Muskingum-type approximations ââ¬â Which have modest data requirements Complex like Muskingumââ¬âCunge methods ââ¬â Where the typically calibrated Muskingum routing parameters are related to physical and hydraulic characteristics such as reach length, flood wave celerity, unit width discharge and channel bed slope Highly complicated like the solution of the full dynamic flow i. e. St Venant equations ââ¬â Which require surveyed cross-sectional channel profiles and flow resistance data Out of these the Muskingum and Muskingumââ¬âCunge methods are well established in the hydrological literature, and the modest data requirements make these procedures attractive even though more rigorous hydraulic models are available for unsteady flow routing.

Battle of Pea Ridge in the Civil War Battle of Pea Ridge - Conflict and Dates: The Battle of Pea Ridge was fought March 7-8, 1862, and was an early engagement of the American Civil War (1861-1865). Armies Commanders: Union Brigadier General Samuel R. Curtis10,500 men Confederate Major General Earl Van Dorn16,000 men Battle of Pea Ridge - Background: In the wake of the disaster at Wilsons Creek in August 1861, Union forces in Missouri were reorganized into the Army of the Southwest. Numbering around 10,500, this command was given to Brigadier General Samuel R. Curtis with orders to push the Confederates out of the state. Despite their victory, the Confederates also altered their command structure as Major General Sterling Price and Brigadier General Benjamin McCulloch had shown an unwillingness to cooperate. To keep the peace, Major General Earl Van Dorn was given command of the Military District of the Trans-Mississippi and oversight of the Army of the West. Pressing south into northwest Arkansas in early 1862, Curtis established his army in a strong position facing south along Little Sugar Creek. Expecting a Confederate attack from that direction, his men began emplacing artillery and fortifying their position. Moving north with 16,000 men, Van Dorn hoped to destroy Curtis force and open the way to capture St. Louis. Eager to destroy outlying Union garrisons near Curtis base at Little Sugar Creek, Van Dorn led his men on a three-day forced march through severe winter weather. Battle of Pea Ridge - Moving to Attack: Reaching Bentonville, they failed to capture a Union force under Brigadier General Franz Sigel on March 6. Though his men were exhausted and he had outrun his supply train, Van Dorn began formulating an ambitious plan to assault Curtis army. Dividing his army in two, Van Dorn intended to march north of the Union position and strike Curtis from the rear on March 7. Van Dorn planned to lead one column east along a road known as the Bentonville Detour which ran along the north edge of Pea Ridge. After clearing the ridge they would turn south along the Telegraph Road and occupy the area around Elkhorn Tavern. Battle of Pea Ridge - McCullochs Defeat: The other column, led by McCulloch, was to skirt the western edge of Pea Ridge then turn east to join with Van Dorn and Price at the tavern. Reunited, the combined Confederate force would attack south to strike at the rear of the Union lines along Little Sugar Creek. While Curtis did not anticipate this type of envelopment, he did take the precaution of having trees felled across the Bentonville Detour. Delays slowed both Confederate columns and by dawn, Union scouts had detected both threats. Though still believing that Van Dorns main body was to the south, Curtis began shifting troops to block the threats. Due to the delays, Van Dorn issued instructions for McCulloch to reach Elkhorn by taking the Ford Road from Twelve Corner Church. As McCullochs men marched along the road, they encountered Union troops near the village of Leetown. Dispatched by Curtis, this was a mixed infantry-cavalry force led by Colonel Peter J. Osterhaus. Though badly outnumbered, the Union troops immediately attacked around 11:30 AM. Wheeling his men south, McCulloch counterattacked and pushed Osterhaus men back through a belt of timber. Reconnoitering the enemy lines, McCulloch encountered a group of Union skirmishers and was killed. As confusion began to reign in the Confederate lines, McCullochs second-in-command, Brigadier General James McIntosh, led a charge forward and was also killed. Unaware that he was now the senior officer on the field, Colonel Louis HÃ ©bert attacked on the Confederate left, while the regiments on the right remained in place awaiting orders. This assault was halted by the timely arrival of a Union division under Colonel Jefferson C. Davis. Though outnumbered, they turned the tables on the Southerners and captured HÃ ©bert later in the afternoon. With confusion in the ranks, Brigadier General Albert Pike assumed command around 3:00 (shortly before HÃ ©berts capture) and led those troops near him in a retreat north. Several hours later, with Colonel Elkanah Greer in command, many of these troops joined rest of the army at Cross Timber Hollow near Elkhorn Tavern. On the other side of the battlefield, fighting began around 9:30 when the lead elements of Van Dorns column encountered Union infantry in Cross Timber Hollow. Sent north by Curtis, Colonel Grenville Dodges brigade of Colonel Eugene Carrs 4th Division soon moved into a blocking position. Battle of Pea Ridge - Van Dorn Held: Rather than pressing forward and overwhelming Dodges small command, Van Dorn and Price paused to fully deploy their troops. Over the next several hours, Dodge was able to hold his position and was reinforced at 12:30 by a Colonel William Vandevers brigade. Ordered forward by Carr, Vandevers men attacked the Confederate lines but were forced back. As the afternoon wore on, Curtis continued to funnel units into the battle near Elkhorn, but Union troops were slowly pushed back. At 4:30, the Union position began to collapse and Carrs men retreated back past the tavern to Ruddicks Field about a quarter mile to the south. Reinforcing this line, Curtis ordered a counterattack but it was halted due to darkness. As both sides endured a cold night, Curtis busily shifted the bulk of his army to the Elkhorn line and had his men resupplied. Reinforced by the remnants of McCullochs division, Van Dorn prepared to renew the assault in the morning. Early in the morning, Brigadier Franz Sigel, Curtis second-in-command, instructed Osterhaus to survey the farmland to the west of Elkhorn. In doing do, the colonel located a knoll from which Union artillery could strike the Confederate lines. Quickly moving 21 guns to the hill, Union gunners opened fire after 8:00 AM and drove back their Confederate counterparts before shifting their fire to the Southern infantry. As Union troops moved into attack positions around 9:30, Van Dorn was horrified to learn that his supply train and reserve artillery was six hours away due to a mistaken order. Realizing he could not win, Van Dorn began retreating east along the Huntsville Road. At 10:30, with the Confederates beginning to leave the field, Sigel led the Union left forward. Driving the Confederates back, they retook the area near the tavern around noon. With the last of the enemy retreating, the battle came to an end. Battle of Pea Ridge - Aftermath: The Battle of Pea Ridge cost the Confederates approximately 2,000 casualties, while the Union suffered 203 killed, 980 wounded, and 201 missing. The victory effectively secured Missouri for the Union cause and ended the Confederate threat to the state. Pressing on, Curtis succeeded in taking Helena, AR in July. The Battle of Pea Ridge was one of the few battles where Confederate troops possessed a significant numerical advantage over the Union.

Basketball why is it my number one US best sports and different in Research Paper
Basketball why is it my number one US best sports and different in rules from NCCA - Research Paper Example The five players from each team may be on the court at one time and substitutions are unlimited though they can only be done when play is stopped. A team can score a field goal by shooting the ball through the hoop during regular play. A regulation basketball hoop consists of a rim 18 inches in diameter and 10 feet high mounted onto a backboard. Afield goal scores two points for the shooting team if a player is touching or closer to the hoop than the three point line while three points are scored if the player is outside the three-point line. The team with more points at the end of the game emerges the winners. It is evident that basketball is one of the best and most popular sports in the USA. It has taken a big role in shaping the cultures of many a people, the young and the old alike. One of the reasons making basket ball a popular sport is street basket ball, a spin-off basket ball played by millions of people. Street basket ball players are both females and males with the ages ranging between 5 and 65 years. Kids start familiarizing themselves with the sport at kindergarten levels. A personââ¬â¢s life as a street ball player usually takes many years as it doesnââ¬â¢t require much practice because it is played for fun (Mallon, 49). This introduction of boys and girls to basketball at such a young age has gone a long way in popularizing the game and in most cases street basket ball players proceed to becoming professionals in the sports. Another reason why basketball has been considered one of the most popular sports in USA is the roles played by the National Basketball Association.
