Going to War or Going to School
On March 19, 2003 former President George W. Bush declared war on Iraq, two years after declaring his war on terror. By the end of the year he had mobilized and shipped fifty thousand soldiers to Iraq. The political cartoon designed by Jim Borgman offers commentary on past socio-economic issues, suggesting that certain young adults risk life and limb not just for patriotism but for career opportunities. . Since the September 11 attacks the United States government has been on a quest to seek vengeance. On March 19, 2003 the United States government declared War on Iraq. Over fifty thousand troops were deployed in 2003 and over one hundred ninety thousand were recruited that year by four different branches of the military. Rationally most find it noble to enter into a cause such as the military, it gives one a true sense of pride. But the reality of it is that your quest for honor, respect, and nobility must be pure in every shape and form. Borgmanââ¬â¢s cartoon has the ability to question ones true motives by attacking your logic. His use of logos is also transferred into the quote at the top of picture, ââ¬Å"I figure itââ¬â¢s easier to find a war than a job these days. â⬠The message should be and is clearly conveyed to any reader but shocking nonetheless. Mr. Borgman is targeting the attention of young adults who have just recently graduated, those who are confused and lacking true guidance. You can see the same blank and confused look on one of his characters, the recent graduate. Curiously wondering whether the soldier is correct or whether he just wasted four years of his life. But its perfectly natural to be scared when your stepping out of a comfort zone and into something new. Itââ¬â¢s like being a kid in a candy store, your senses are just so overwhelmed that you donââ¬â¢t have a grasp on what you truly need to be doing. One looks for the first thing that makes sense to them and then proceeds to stick with it. You might be curious and wondering what can the military offer me that I canââ¬â¢t get with a college degree. Well let me tell you that some of the great benefits, they offer an opportunity to gain qualities such as leadership and follow through. Key elements needed to be successful in society today. Another huge attraction for some is the G. I. Bill, which gives any service men and women the opportunity to attend any institution courtesy of the taxpayers. Itââ¬â¢s hard to refer to ethics when speaking about the persuasiveness of political cartoons; personally they have nothing to do with one another. The cartoon surfaced right after the U. S. eclared war against Iraq, showing Borgmanââ¬â¢s use of kairos. Which made it apparent that he was trying to push a point upon the American public. Society as a group stays in the shadows of current news but that is because media corporations filter stories, but thatââ¬â¢s a different topic. In conclusion I hope that this photograph has altered your outlook not just on previous issues but has given you a current grasp on what is going on today. My mother once told me that history finds a way of repeating itself, the question becomes are we going to do something about it.

Homer Adolph Plessy v Ferguson
In 1890, the State of Louisiana passed Act 111 that required separate accommodations for African Americans and Whites on railroads, including separate railway cars, though it specified that the accommodations must be kept ââ¬Å"equalâ⬠. On any other day in 1892, Plessy with his pale skin color could have ridden in the car restricted to white passengers without notice. He was classified ââ¬Å"7/8 whiteâ⬠or octoroon according to the language of the time. Although it is often interpreted as Plessy had only one great grandmother of African descent, both of his parents are identified as free persons of color on his birth certificate. The racial categorization is based on appearance rather than genealogy. Hoping to strike down segregation laws, the Citizens' Committee of New Orleans (Comite des Citoyens) recruited Plessy to violate Louisiana's 1890 separate-car law. To pose a clear test, the Citizens' Committee gave advance notice of Plessy's intent to the railroad, which had opposed the law because it required adding more cars to its trains. On June 7, 1892, Plessy bought a first-class ticket for the commuter train that ran to Covington, sat down in the car for white riders only and the conductor asked whether he was a colored man. The committee also hired a private detective with arrest powers to take Plessy off the train at Press and Royal streets, to ensure that he was charged with violating the state's separate-car law. In his case, Homer Adolph Plessy v. The State of Louisiana, Plessy argued that the state law which required East Louisiana Railroad to segregate trains had denied him his rights under the Thirteenth and Fourteenth Amendments of the United States Constitution. However, the judge presiding over his case, John Howard Ferguson, ruled that Louisiana had the right to regulate railroad companies as long as they operated within state boundaries. Plessy sought a writ of prohibition. The Committee of Citizens took Plessy's appeal to the Supreme Court of Louisiana, where he again found an unreceptive ear, as the state Supreme Court upheld Judge Ferguson's ruling. Undaunted, the Committee appealed to the United States Supreme Court in 1896. Two legal briefs were submitted on Plessy's behalf. One was signed by Albion W. Tourgee and James C. Walker and the other by Samuel F. Phillips and his legal partner F. D. McKenney. Oral arguments were held before the Supreme Court on April 13, 1896. Tourgee and Phillips appeared in the courtroom to speak on behalf of Plessy. It would become one of the most famous decisions in American history because, for the first time, it established that state-mandated racial segregation was protected by federal law. Arrested, tried and convicted of a violation of one of Louisiana's racial segregation laws, he appealed through Louisiana state courts to the U. S. Supreme Court, and lost. The resulting ââ¬Å"separate-but-equalâ⬠decision against him had wide consequences for civil rights in the United States. The decision legalized state-mandated segregation anywhere in the United States, as long as the facilities provided for both blacks and whites were putatively ââ¬Å"equalâ⬠. In a 7 to 1 decision handed down on May 18, 1896, (Justice David Josiah Brewer did not participate) the Court rejected Plessy's arguments based on the Fourteenth Amendment, seeing no way in which the Louisiana statute violated it. In addition, the majority of the Court rejected the view that the Louisiana law implied any inferiority of blacks, in violation of the Fourteenth Amendment. Instead, it contended that the law separated the two races as a matter of public policy.

Essay on The Segregation of Gender Digital Divide
In todays society, the factor of segregation is no longer based on the discrimination of race, but rather the knowledge of digital capabilities. The development of technology and its advancement separates many individuals through its availability. The term ââ¬Å"digital divideâ⬠represents the increase in the gap between those who have technology readily available to them and those who do not have access to computers and Internet usage. The lack of access to these technologies and the lack of understanding the digital capabilities that change daily, reflects this growth. Understanding the increase in the gap must be analyzed from factors that may cause a hindrance in being able to progress along with technology. With its development, theâ⬠¦show more contentâ⬠¦Cooper and Weaver use the term ââ¬Å"psychological genderâ⬠to identify those children who will learn that there are ââ¬Å"roles, norms, and obligationsâ⬠regardless of understanding the significance of their physical differences (33). Jan A.G.M van Dijk, a professor of sociology and computer science, emphasizes how individuals are taught to believe that some objects, technologies, and even language is appropriate under the idea of gender specification. The idea that the use of technology and its devices is predominately male based has been instilled into the minds of individuals and are present in their upbringing. In the text, The Deepening Divide: Inequality in the Information Society, this identification of this idea starts with the objects of play during adolescence by stating, Gender differences in the appropriation of technology start very early in life. Little boys are the first to pick up technical toys and devices, passing the little girls, most often their sisters and small female neighbors or friends. These girls leave the operation to the boys, perhaps at first because the girls are less secure in handling them. Here a long process of continual reinforcement starts in which the girls ââ¬Å"neverâ⬠learn to operate the devices and the boys improve.

Prevention And Prevention Of Immunization - 1113 Words
Immunization can be defined as the process in which a person, typically at an infant age, is made immune to infectious diseases usually through the administration of vaccines. Doctors and healthcare providers recommend vaccainations to infants to protect them from common diseases that can be deadly especially to young children and infants. The process, as explained by the Center for Disease Control and Prevention (CDC), is referred to as the ââ¬Å"4:3:1:3 series,â⬠which represents the number of dosages of vaccines required to fend off diseases such as mealses, mumps, tetsnus, and many others (ââ¬Å"Immunizationâ⬠). In recent years there has been a movement mainly empowered by new mothers to forgo some or all vaccinations for their children. The following paragraphs will include an anylsis uncovering what has caused a decrease in vaccinations of children, as well as, exploring what effects this has had on the community. When observing statsically research over the past tw o decades there seems to be two consistent themes for reasonings behind forgoing vaccinations of children which will be discussed later. However, these two reasonings might shed light on the topic and help explain the existence of this trend. A report released by the California Department of Public Safety shows that there has been an increase for both public and private schools from 2007 to 2014 of 2.6% to 5.7% of students receiving expemtions from vaccinations at the statewide level.

World Literature Essay Summary Example For Students
World Literature Essay Summary How a persons nurturing and upbringing triumphs over the natural way of being, in relation to Grenouille in Perfume and the society in Chronicle for a Death Foretold. Every living thing has a natural way of being. Be it a plant which will naturally incline toward the sun or a nocturnal animal which will only come out at night, all living things will have a expected way of behaving, and this does not exclude human beings. However, this original way of existence can be infringed by the location and culture in which a human being is brought up in, as well as the occurrences which take place during said persons life. The following essay shall show how the upbringing which Grenouille received in Perfume (First Published in German1985. First Translated in 1986) by Patrick Sà ¯Ã ¿Ã ½skind (German born March 26, 1949 Present Day) affects the unfolding of the events in the book, and how the way the society is cultivated provokes events which ultimately cause Santiago Nasars death in Chronicle of a Death Foretold (First Published in 1981. First Translated in 1982) by Gabriel Garcia Marquez (Spanish born March 6, 1927 Present Day) In the commencement of Perfume, we firstly see how Grenouille acts in the natural way that any living thing would, but as Grenouilles life develops, while he is being brought up by different care takers and different mentors, we can see certain crucial moments in his life which shed light in explaining why Grenouille becomes the way he does. At the start of his life, his first care-taker instantly takes an enormous disliking toward him. We see this when she speaks to Father Terrier, she constantly makes remarks about how the child is strange and insults him on various occasions for example saying he is possessed by the devil1. Perhaps, even though a baby, he still understood this because of a babys natural way of interpreting things, whereby peoples emotions and thoughts reflect a certain aura around the person, and small babies see these auras. Therefore, the first person he ever lived with seemed to be continuously disgusted by Grenouille, and alas may have already commenced the cr eation of his complex; his hate and disgust for humanity. Father Terrier later on also shows his disgust for Grenouille as he makes Terrier shudder and feel sick to his stomach2, and as Buisse does, he wanted to get rid of him as quickly as possibleimmediately if possible3 and ergo abandons him. The previous is, what I believe the beginning of Grenouilles detestation for humanity, and this is further induced when he lives with Madame Gaillard who in a sense treats him like a pet in the manner in which she feeds him, serving up three meals a day and not the tinniest snack more4. We can assume that his residence was overcrowded with orphans due to the fact that Paris produced over ten thousand new orphans a year5 and I imagine that these children were dirty and smelt. This simple situation is addition to the occasions where the children conspired to suffocate him6 may have been one of the things which cause Grenouilles misanthropy, as when he becomes an adult, he despises the smell of humans and he also hates being around them. Here we see how the lifestyle in which Grenouille grew up could possibly cause the deterioration of his natural instincts as the dislike of being around others is against the natural law of survival whereby animals naturally seek safety in groups. Greno uille on the other hand prefers being in solitude as we see later on in the novel where he lives secluded from humanity on the mountain of solitude7 inside a cave in which never in his life had he felt so secure8. (I dont know if that last phrase is grammatically correct) Was the 5th Century BCE a Golden Age for Athens? EssayAnother incident involving an unnatural catholic trait is seen when Divina Flor confesses that the true reason her mother had not told Santiago that He was going to be killed is because in the depths of her heart, she wanted them to kill him18. This is because Santiago, on various occasion made sexual advances to Divina Flor, and this would trigger a memory of her mothers where Santiagos father would do likewise to Victoria Guzmans (Divinas mother). We can therefore see how a previous event in Victorias life caused her natural catholic ideology to disappear, as she breaks one of the Ten Commandments, and wishes ill upon someone. Note: the above paragraph has been removed as I believe it isnt completely relevant, but u have left it there in order to see what you opine about it Garcia shows this breech in Catholic standards in order to show the inexistence of natural religious and moral codes which have been usurped by the societys cultural upbringing. To further implement this lack of religion, Garcia shows the coming of the bishop as a joke, whereby he wont even get off the boathell give an obligatory blessingand go backhe hates this town.19 To conclude the triumph of upbringing over natural instincts, I will take a look at the influence of sex in both novels. Our animalistic instincts tell us, there is no rule in not having premarital relations. This is what Angela does; she acts naturally, while society expects her to not fornicate until she is married, as everyone is nurtured with the idea that a woman must remain innocent until unified in matrimony. On the other hand, we do not see the same train of thought when referring to a man. Santiago clearly did as he pleased as he tells Divina Flor the time has come for you to be tamed.20 With this we see that the society has been nurtured into a hypocritical way of thinking where society sees in undignified for a woman to act naturally while a man can do as he pleases. This contrasts with how Grenouille as he has the opportunity to do as he pleases with a female, but he only does what he needs to reach his destination. Again Grenouilles natural instinct had been usurped by h is upbringing whereby he was nurtured by Baldini and Grimal to not deviate from his path no matter what.

The Pendulum Coursework Essay Example
The Pendulum Coursework Essay Aim: The aim of this experiment is to find out if a certain variable effects the period of a pendulum. The variable we will be testing in this project is the length of the string.Prediction: I predict that the longer the piece of string, the longer it will take the pendulum to complete one period. I also predict as the length of the string goes up by 10cm, the period will increase by roughly 0.15 seconds.Apparatus: -Piece of string (longer than 95cm)To attach and swing the weight ball off.-RulerTo measure the piece of string.-ProtractorTo measure the angle between the string and the floor soIt is the same every time.-Stop watchTo measure how long the period is-Pencil/PenTo record our results-Weight ball (40g)To attach and hang on the end of the string to weigh itDown and to make it into a pendulum.-ClampTo attach the pendulum 2 the table so it has room toSwing above the floor.-Clamp attachment fittingTo attach the string to the clamp.Method:1) Firstly, we have to determine, how many lengths we ant to compare, and also (in cm) how long each piece of string is.We have decided to go up in fives i.e. 5, 10, 15 etc2) Then we have to draw up a table o record all f our results.3) Next we have to collect all our apparatus.4) Firstly, we will measure a piece of string to the length required, plus a bit for excess to tie around the weight ball etc5) We then will set up our clamp and attach the string to the clamp attachment and in turn, attach the weight ball to the string.6) After all is set up, we will need to wind up the string around the clamp to the lowest measurement ready to begin the experiment. (we will measure it with a ruler)7) We will then pull back the string ready to begin at about 90d degrees ready to time the period. This will be our preliminary experiment.8) Whilst one person holds he string and lets go, another person times it in seconds (using a stop watch) how long it takes for the string to swing once, forward and back ant then stop the watch at the time it reaches the end of the period.9) We will then record the first result in the table.10) Because this is the preliminary experiment, we will only trial each measurement once.11) We will then continue this over and over until weve done it once for every measurement.12) After we have recorded all of our preliminary results, we will look at he ranges etcto see if we need to make any changes to the experiment.13) Next we will completely redo the whole experiment, starting at 5cm up to about 95cm at about 90 degrees.14) Finally we will find out the averages for each length and record the results on to a graph.How this will be a fair test:Because every time we do the experiment, we will only change one variable at a time and keep everything else the same i.e. the angle at 90 degrees from the floor, the weight ball of weight of 40g etcThe only variable we will change is the length of the string.Safety Precautions:We will always keep to strict safety precautions by which we will stand back from the pendulum as it swings so it doesnt hit us. We will tie our hair back so not to get caught in the pendulum and wear safety goggles to protect our eyes.Background ResearchPendulum clocks have been used to keep time since 1656, and they have not changed dramatically since then. Pendulum clocks were the first clocks made to have any sort of accuracy.A pendulum clock is made from these parts:* There is the face of the clock, with its hour and minute hand (and sometimes even a moon phase dial).* There are one or more weights (or, if the clock is more modern, a keyhole used to wind a spring inside the clock we will stick with weight-driven clocks in this article).* And, of course, there is the pendulum itself.The Weight:The weight is used so that the pendulum can run for a longer amount of time, without having to be tampered with. It acts as an energy storage device so you can leave it unattended. If you pull on the string or cord that attaches the weight upwards, you autom atically give the weight potential energy. It then uses this potential energy in a moment, as the weight falls to drive the clocks mechanism. However the weight of the weight does not effect the period of the pendulum.The pendulum consists of either a light rod or piece of string. St the end o this rod o string there is a weight attached. We know that, so long the angle of the piece of string is less than 20 degrees, the period will remain constant however, it is still not a precise measurement even then. When you have it over the angle of 20 degrees, the pendulum has to go further but at a greater velocity due to the fact that it falls from a greater height, meaning it is at a more acute angle than normal. Overall, this means that the pendulum traverses a longer distance in a shorter amount of time.The pendulum demonstrates an almost continuous perpetual motion, until it finally sops, dues to friction. The pendulum has a falling motion. The pendulum keeps a very regular beat, which is why for many years it was used in clocks.The period of a pendulum can be affected or not affected by three variables:- The weight of the pendulum.- The length of the pendulum.- The angle of which the pendulum departs.These are the main factors which people commonly presume to have an effect on the period of the pendulum; however, the weight of the pendulum has little or no effect at all, neither does the angle of which the pendulum departs. On the other hand, length of the pendulum is correct, due to the fact it has to traverse a further distance. The pendulum period is related only to the length of the pendulum and the force of gravity. However due to the fact that gravity remains constant at any particular point anywhere in the planet, this means the length of the pendulum is the only thing that effects the period of a pendulum.Preliminary TrialLength (cm)Trial 150.91100.95151.07201.18251.20301.22351.42401.47451.58501.45These results arent very accurate and dont really follow a certain pattern. Also, I dont think they cover a big enough range so we dont really get a chance to see how length effects the pendulum later on when the string is longer. Therefore, We are going to change the difference between each length from 5cm -10cm.This is the new Method:1) Firstly, we have to determine, how many lengths we ant to compare, and also (in cm) how long each piece of string is.We have decided to go up in tens i.e. 5, 15, 25 etc2) Then we have to draw up a table o record all f our results.3) Next we have to collect all our apparatus.4) Firstly, we will measure a piece of string to the length required, plus a bit for excess to tie around the weight ball etc5) We then will set up our clamp and attach the string to the clamp attachment and in turn, attach the weight ball to the string.6) After all is set up, we will need to wind up the string around the clamp to the lowest measurement ready to begin the experiment. (we will measure it with a ruler)7) We will then pu ll back the string ready to begin at about 90d degrees ready to time the period. This will be our preliminary experiment.8) Whilst one person holds he string and lets go, another person times it in seconds (using a stop watch) how long it takes for the string to swing once, forward and back ant then stop the watch at the time it reaches the end of the period.9) We will then record the first result in the table.10) Because this is the preliminary experiment, we will only trial each measurement once.11) We will then continue this over and over until weve done it once for every measurement.12) Next we will completely redo the whole experiment, starting at 5cm up to about 95cm at about 90 degrees.13) Finally we will find out the averages for each length and record the results on to a graph.ObtainingThe Table of results for altering the lengths of a pendulum and the effect it has on the periodLength (cm)TrialTrial 2Trial 3Average (of all results from all three trials)50.90 (0.9)0.51 (0.5 )0.61 (0.6)0.67 (0.7)150.87 (0.9)0.77 (0.8)0.74 (0.7)0.79 (0.8)251.28 (1.3)0.99 (1)1.05 (1.1)1.11 (1.1)351.39 (1.4)1.26 (1.3)1.26 (1.3)1.30 (1.3)451.45 (1.5)1.39 (1.4)1.52 (1.5)1.59 (1.6)551.56 (1.6)1.68 (1.7)1.76 (1.8)1.67 (1.7)651.65 (1.7)1.64 (1.6)1.74 (1.7)1.68 (1.8)751.81 (1.8)1.43 (1.4)1.42 (1.4)1.55 (1.6)852.08 (2.1)2.08 (2.1)2.04 (2)2.07 (2.1)952.21 (2.2)2.24 (2.2)2.28 (2.3)2.24 (2.2)EvaluationMy overall prediction is correct; the longer the piece of string, the longer it will take the pendulum to complete one period, however on average, it doesnt increase by 0.15 seconds, but it increases by 0.1 seconds. But still this is not accurate. I have quite a few anomalies.However, like in what I discussed in my analysis, I did make some mistakes with accuracy etc If I were to redo this experiment, then I would consider making sure I got the timings absolutely perfect. Which although would take a lot of time which I didnt have this time around, so maybe this shows to get excellent r esults you need a lot of time and it takes a lot of effort.One anomaly that in particular stands out is when the string is of length 75 cm and the result is 1.55 seconds. Whereas the result just before it is 65cm and 1.68; before this result, the trend line goes up consistently, however, when it hits this point, it goes down by 14 seconds, which is a pretty large jump and the result after it is at 85 cm and 2.07. There is then a massive jump to the next point. It goes up by 0.51 seconds, which is a massive increase. It is the biggest increase in the whole experiment. This again shows another flaw in my experiment, or maybe just reinforces the anomaly before hand.It is very low compared to 85cm but is also lower than 65 cm which cannot be right because, as we discovered, as the length of the string increases, so to does the length of the period. Therefore this is incorrect. Looking back at the table, the first trial for 75 cm is 1.81 cm, which seems pretty accurate but then for trial 2 and 3, it slips to 1.43 and 1.42 seconds. This could have happened because, the unbeknown to us the string slipped or tightened in this case, or it bashed the table or we timed it wrong by stopping the stopwatch too early or starting it too late. This is an easy mistake to make however, on the other hand, I could have measured the results before of after inaccurately in the same way, timing inaccurately. This is quite unlikely though. Again if I were to do the experiment again I would have to be more accurate.I dont think my results are that reliable, and dont always fit the formula. And there a lot of anomalies in the separate trials. If I were to do it again, I would do it in more time with more accuracy. I would maybe even do an even bigger range and perhaps another trial.Length (cm)Trial 1Trial 2Trial 3Trial 4Trial 5Average (of all results)525456585105125145156185I would also check the length of the sting hadnt slipped or adjusted itself between each trial.AnalysisIf I pick t wo points on the line of best fit, near the end and the beginning:0.80 and 2.20The co-ordinates are0.80 = (3,8)2.20 = (17,22)22-8=1417-3=1414/14=144?à ¯Ã ¿Ã ½ = 39.539.5/1=39.5(39.5-9.8)/9.8 = 3.0306=33 is the percentage error so this shows my results arent completely accurate. Therefore if I were to do it again, I would need to be more accurate.Between points 25, 35,45 and 55 it goes up almost identically, very, very consistently. It goes from 1.11 (1.1) to 1.30 (1.3) to 1.59 (1.6) to 1.67 (1.7). The third goes slightly out, but they are the most accurate ones.This shows good and accurate timings, which is very good n the fact were trying to compare the length of string and the how it affects the time it takes the pendulum to complete one period.The rule for this graph is, as the length of string increases, the time it takes the pendulum to complete period increases at the same time. My graph clearly shows this as the line of best fit goes up diagonally right.tà ¯Ã ¿Ã ½ = (4? à ¯Ã ¿Ã ½/g)L.39.5/39.5=11 times 5 = 5Therefore should be at point 5 (0.5) on the graph.Therefore our result is inaccurate.However, it does relate to my background research because it said that length would be the only variable able to change the length of the period. Also that the longer the string the longer it would take to complete a period. This means it does link closely to the background research, just not extremely accurately. The main theory does.ConclusionThe rule for this graph is, as the length of string increases, the time it takes the pendulum to complete period increases at the same time. My graph clearly shows this as the line of best fit goes up diagonally right. In my prediction I said that it goes up by roughly 0.15 in every 10cm but I think its now more closer to 0.1 seconds in every 10 cm.
