The Underground Railroad - 2038 Words

The Underground Railroad was the name of the network that was used by enslaved African Americans. It consisted of very intricate routes that were used so that those moving along its path could lose pursuers traveling under the guise of darkness and staying in safe houses during the day. The goal of the railroad was to get the slaves from the South to the Free states and to Canada where slavery was prohibited. A slave knew that once they crossed the border into any one of the Free states that they were safe from the cruelty of being a slave as long as they were not captured by slave catchers. A reason why the railroad was so successful was because they had allies who were both black and white. One such example is the Quakers, as well as the most astounding former slaves such as Harriet Tubman who was born a slave in Maryland. When she was a teen, an incident caused her to have seizures, severe headaches and narcoleptic episodes for the rest of her life. Sojourner Truth, another pion eer of the Underground Railroad, was born a slave in New York back when it was still a slave state in 1797. She is a famous abolitionist known for her speech, â€Å"Ar’n’t I a Woman?† Still another famous Underground Railroad freedom fighter was Anna Murray Douglas who was born free; she is the first wife of Fredrick Douglass, and she helped him escape to freedom by giving him money she had saved.

Essay on Violent Video Games Affect on Youth Today

In the more recent times it seems as if America’s youth is becoming more violent. Concern for those aspects in our society which influence violent acts has become an issue since the tragedy at Columbine High School on April 20, 1999. Many feel one aspect of today’s society affecting our nation’s youth in a negative manner is video games. Is this form of entertainment really a factor in teen violence? I think not. We should blame the parents for teen violence, not video games. nbsp;nbsp;nbsp;nbsp;nbsp;John Holts article, â€Å"Kinds of Discipline† states that the youth watch very carefully what people around them are doing and want to do the same. The example of these grownups is contagious (490). Now days the media makes it seem like it’s†¦show more content†¦These games are first person. The player sees through the eyes of the electronic eyes of their character, seeing only their own weapon and whatever is in front of them. The game boards are also set up to resemble hospitals, and often areas that are quite similar to school hallways.One must account for the fact that many of the weapons used are those of the sort that do not exist or are only seen in movies. Laser guns and triple barreled grenade launchers are not lifelike and are even less lifelike when used against four-armed monsters. Ken Schroeder’s 1997 article, â€Å"Halving Fun† showed that when confronted with questions concerning the appeal of these games many will say that they enjoy doing things that they â€Å"could never do in real life.† In fact, a ten-year-old girl was quoted to say, â€Å"a video game with someone smashing a guy’s head in is not going to make the kid go out and smash their friend’s head in (73).† So whether or not they are desensitized to the violence does not necessarily make them more prone to it. In the article, â€Å"Video Violence: Where does the Buck Stop,† Deborah Enders explained that video games are also rated for violence. These ratings do not prevent a kid from buying a violent video game though (27-28). This however could also be the parents’ fault.

AP, by John Updike Essay Example For Students

AP, by John Updike Essay In the story AP, by John Updike, the main character Sammy makes the leap from an adolescent, knowing little more about life than what he has learned working at the local grocery store, into a man prepared for the rough road that lies ahead. As the story begins, Sammy is nineteen and has no real grasp for the fact that he is about to be living on his own working to support himself. Throughout the course of the story, he changes with a definite step into, first, a young man realizing that he must get out of the hole he is in and further into a man, who has a grasp on reality looking forward to starting his own family. In the beginning, Sammy is but a youth growing up learning what he knows about life in small town grocery store. His role models include, Stokesie, the twenty-two year-old, supporting a family doing the same job Sammy does yet aspiring to one day have the managers position, and Lengel, the store manager who most certainly started out in the same place that Stokesie and he were already in. Stoksie, the great role model, continues to be as adolescent as Sammy, with his Oh, Daddy, I feel so faint, and even Sammy sees this noting that as far as I can tell thats the only difference between he and I. Sammy whittles away his days looking at pretty girls and thinking about the ways of people. He hardly realizes that this is how he will spend his entire existence if he doesnt soon get out of this job. During this day that will prove to change his life, he makes the step towards his realization. He decides that he doesnt want to spend the rest of his life working at an AP competing for the store managers position. Sammy thinks to himself about his parents current social class and what they serve at cocktail parties. And, in turn, he thinks about what he will be serving, if he stays at the AP, When my parents have somebody over they get lemonade and if its a real racy affair Schlitz in tall glasses with Theyll Do It Every Time cartoons stenciled on. He must get out and the sooner the better. He is still just an adolescent who hasnt completely thought through his decision and yet his mind is made up. He quits his job using the girls merely as an excuse to get out. His final journey to manhood is a short one. He looks around for his girls and notices that they have already left, but he knew that was a futile cause to begin with. And he steps outside to see the world and its opportunities as well as its responsibilities in front of him. Although, Sammy could see how hard the world would be hereafter, he knew that what was done had to be done. In hindsight, Sammy still knew he had done the right thing as shown  by Now here comes the sad part of the storybut I dont think its so sad myself.

The Pursuit Of Happiness Essays - British Films,

The Pursuit Of Happiness Love is perhaps the most actively sought moral objective of ones life. And though marriage is often thought to be the logical consequence of love, it is Oscar Wildes contention in his satire, The Importance of Being Earnest, that love begets bliss and marriage thwarts this course of bliss. Algernon Moncrieff spends very little time falling in love and the rest of the time striving toward engagement. Wilde demonstrates through him that once one becomes intent upon achieving a goal, the individuals motivation becomes a matter of action rather than truth. Algernon is no longer driven by a moral objective; instead, he becomes intent upon achieving a societal standard. The truth is rarely pure, and never simple (35). Love is truth. Marriage results in the systematic complication of love. Algernon becomes disillusioned in the process of seeking truth. In defining Algernons preconceived notion of marriage and then describing the subsequent earnest pursuit of engagement, Wilde achieves a con sequential climax that satirizes marriage. Algernon is a pompous man of seemingly strong, albeit unconventional, convictions. Wilde uses him for the sole purpose of mocking the sanctimonious institution of marriage. In the beginning of the play, Algernon considers Jacks intent to propose to Gwendolen to be business, not pleasure (30). Yet eventually Algernon also resolves to propose to Cicely, discrediting his own established belief: I really dont see anything romantic in proposing. It is very romantic to be in love. But there is nothing romantic about a definite proposal. Why, one may be accepted. One usually is, I believe. Then the excitement is all over. The very essence of romance is uncertainty (30). Algernon clearly, at one point, sees marriage as a means to an end. Once he meets Cecily, however, the idea of maintaining truth above reality is hard to rationalize; he wants only to move forward in the proper manner established by society. Upon initially hearing about Cicely, Algernon is intrigued. She is no more than a name on a cigarette case. After intense probing, Jack discloses Cicelys identity. Algernon then tells Jack, I would rather like to see Cicely (51). She suddenly becomes more of a name to Algernon, and he begins to pursue her as more than a person; she becomes his moral objective. When Jack reveals to Gwendolen his address in the country, Algernon secretly writes the address on his shirt-cuff (53) in hopes of going to meet Cicely. Shortly after his first encounter with her, he reveals to Jack, I am in love with Cicely, and that is everything (71). This newfound love is his truth. He admits to her, Cicely, ever since I first looked upon your wonderful and incomparable beauty, I have dared to love you wildly, passionately, devotedly, hopelessly (73). Yet Algernon quickly abandons the truth imbedded in love, his moral objective, and instead opts for convention. I dont care for anybody in the whole world but you. I love you, Cecily. You will marry me, wont you? (74). The irony displayed through Algernons self-contradiction is the pivotal progression that eventually results in Wildes intended resolution of the play Algernon reveals he simply wanted to be engaged to Cecily (88) to Jack, who quickly dismisses him. There is certainly no chance of your marrying Miss Cardew (88). It is this obstacle, and its respective denouement, which outlines the basis of Wildes thematic emphasis. Prospective marriage, by means of engagement, serves not only as an obstacle but also a resolution. In Algernons view, Cecily is the sweetest, dearest, prettiest girl in the whole world. And [he doesnt] care twopence about social possibilities (98). In actuality, however, it is the promise of social possibilities that motivate him to an end. For, it is his eventual conformity to societal norms that destroys the moral truth he once held dear. By the time Wilde establishes definite engagement for the couple, Algernon and Cicely embrace, and the play ends. As Algernon said in Act 1, The excitement is all over (30). This anti-passionate climax epitomizes Wildes sardonic wit, humoring a societal institution. Algernon achieve s what he believes he wants, but loses his motivation in the process. Marriage, at one point, seem[ed] to be very problematic to Algernon. His

Free Essays on Fetal Alcohol Syndrome

Fetal alcohol syndrome (FAS) refers to a group of physical and mental birth defects resulting from a woman’s drinking alcohol during pregnancy. FAS now surpasses Down Syndrome and Spina Bifida as the leading cause of mental retardation in the United States. The average IQ for persons with fetal alcohol syndrome is sixty-seven. This occurs in one out of seven hundred fifty births a year. Many of these children are diagnosed with Attention Deficit Disorder, Oppositional Defiant Disorder, and Pervasive Developmental Disorder. The cause of fetal alcohol syndrome is chronic alcohol or drug consumption during pregnancy. Every time a pregnant woman drinks, the alcohol passes through the placenta to the unborn child. Alcohol is more harmful to the fetus than the mother because of the unborn baby’s small size and rapid growth rate. Once a fetus has FAS, the physical and mental damage is irreversible. Fetal alcohol syndrome is totally preventable. No alcohol means no FAS. A pregnant woman shouldn’t abuse drugs either. There is evidence that indicates an occasional glass of wine or beer is not dangerous, but no usage is recommended. The ages most affected are newborns. It effects all races and all socio-economic groups. The signs and symptoms of newborns are poor sucking abilities, poor sleeping habits, irritability, and affects of alcohol withdrawal. Some possible physical abnormalities are a small head circumference below five- percent (Microcephaly). Small eye slits (palpebral fissures), vertical folds of skin extending from upper eyelid to the side of the nose (Epicanthic folds), ridge above upper lip (smooth or indistinct philtrum), protruding forehead, cleft palate, flattening of mid-face, low set or mildly malformed ears, small brain, and hip dislocation and other joint deformalities. Symptoms later on are mental and severe growth retardation, poor coordination and learning disabilities, speech and language difficulties, and ... Free Essays on Fetal Alcohol Syndrome Free Essays on Fetal Alcohol Syndrome Fetal Alcohol Syndrome and Fetal Alcohol EffectsFetal Alcohol Syndrome and Fetal Alcohol Effects Prenatal alcohol exposure is a preventable cause of birth defects, including mental retardation and neurodevelopmental deficits. Since the initial recognition in 1968 of the multiple effects that alcohol can have on the developing fetus [1] and the subsequent delineation in 1973 of fetal alcohol syndrome (FAS), [2] it has become clear that prenatal alcohol exposure can be associated with a wide range of abnormalities. [3] More than 80% of children with FAS demonstrate prenatal and postnatal growth deficiency, mild to moderate mental retardation, microcephaly, infantile irritability, and characteristic facial features. Fifty percent of affected individuals also have poor coordination, hypotonia, attention deficit disorders with hyperactivity, decreased adipose tissue, and other identifiable facial features. Additionally, 20% to 50% of affected children demonstrate a variety of other birth defects, including cardiac anomalies, hemangiomas, and eye and ear anomalies. [2,4,15,16] Even in the absence of growth retardation or congenital abnormalities, children born to women who drank alcohol excessively during pregnancy appear to be at increased risk for attention deficit disorders with hyperactivity, fine-motor impairment, and clumsiness as well as more subtle delays in motor performance and speech disorders. [4] These findings have been referred to as fetal alcohol effects (FAE). As recently described, FAS and FAE produce profound cognitive, behavioral, and psychosocial problems that persist to date of follow-up of those affected. In the most comprehensive and far-reaching study to date, Streissguth et al [5] traced the natural history into adulthood and demonstrated the profound, pervasive, and persistent nature of the biopsychosocial manifestations of these disorders. Cognitively those affected...

Free Essays on Fetal Alcohol Syndrome The Deletrious Effects Of Fetal Alcohol Syndrome This essay will consider information about fetal alcohol syndrome and it's deleterious effects on the unborn fetus and the repercussions that follow after birth and through life. In my opinion alcohol is responsible for the detrimental effects on the innocent, unwilling participants of alcohol abuse through their mother's inability to cope with life's hardships or the inability of understanding the spectrum of affects alcohol can cause on the unborn baby. This essay will show that mother's who drink alcohol, no matter what the quantity, will have a severe impact on her offspring's mental, physical and psychological capabilities commencing in the womb, to birth and through his or her existence. This essay will examine three main topics of discussion. First it will show what fetal alcohol syndrome is and how it affects the prenatal world. Secondly, it will show how it affects the fetus when exposed to alcohol at all stages of life. Finally, it will show the statistics of fetal alcohol syndrome on youths. "Fetal alcohol syndrome (FAS), fetal alcohol effects (FAE), alcohol-related neurodevelopment disorder (ARND), alcohol related birth defects (ARBD) and alcohol-exposed static encephalopathy (SE) are all terms for the defect which occurs to a child when his or her mother drinks alcohol during pregnancy (Streissguth, 5)". It causes a birth defect that targets the brain from the pre-embryonic stage, to the fetal stage and has lifelong consequences. Some of the most crippling secondary disabilities that people with FAS/FAE face include mental health problems, disrupted school experience, inappropriate sexual behavior, trouble with the law, alcohol and drug problems, difficulty caring for their children, and homelessness.

Free Essays on Fetal Alcohol Syndrome Fetal Alcohol Syndrome Objective†¦ After the reading and discussion of my very informative paper, the Student will be able to understand the causes of Fetal Alcohol Syndrome, signs & symptoms, and how as future nurses, we can prevent further complications. What is Fetal Alcohol Syndrome? ¿? Fetal alcohol syndrome (FAS) is a set of physical and mental birth defects that can result when a woman drinks alcohol during pregnancy. When a pregnant woman drinks any type of alcohol, such as beer, wine, or mixed drinks, so does her baby. Alcohol passes through the placenta right into the developing fetus and as a result, the child may suffer lifelong damage. FAS is characterized by three major characteristics: (1) abnormal facial features, (2) growth deficiencies, and (3) central nervous system (CNS) problems. People with FAS may have problems with learning, memory, low birth weight, skeletal deformities, little attention span, communication, vision, and/or hearing. These problems often lead to difficulties in school and problems getting along with others. FAS is a permanent condition. It affects every aspect of an individual’s life and the lives of his or her family. Fetal Alcohol Spectrum Disorders (FASD) is an umbrella term describing the range of effects that can occur in an individual whose mother drank alcohol during pregnancy. These effects may include physical, mental, behavioral, and/or learning disabilities with possible lifelong implications. The term FASD is not intended for use as a clinical diagnosis. Many terms have been used to describe children who have some, but not all, of the clinical signs of FAS. Three terms you may commonly hear are Fetal Alcohol Effects (FAE), Alcohol-Related Neurodevelopment Disorder (ARND), and Alcohol-Related Birth Defects (ARBD). FAE has been used to describe children who have all of the diagnostic features of FAS, but at mild or less severe levels. These include behavioral and/or cog...

Modelling and Simulation of engineering systems Essay

Modelling and Simulation of engineering systems - Essay Example The main advantage of SIMULINK over other programming softwares is that, instead of compilation of program code, the simulation model is built up systematically by means of basic function blocks. Through a convenient graphical user interface (GUI), the function blocks can be created, linked and edited easily using menu commands, the keyboard and an appropriate pointing device (such as the mouse). A set of machine differential equations can thus be modelled by interconnection of appropriate function blocks, each of which performing a specific mathematical operation. Programming efforts are drastically reduced and the debugging of errors is easy. Since SIMULINK is a model operation programmer, the simulation model can be easily developed by addition of new sub-models to cater for various control functions. As a sub-model the induction motor could be incorporated in a complete electric motor drive system (Wade 495-505; Shi 231-235). A generalized dynamic model of the induction motor consists of an electrical sub-model to implement the three-phase to two-axis transformation of stator voltage and current calculation, a torque sub-model to calculate the developed electromagnetic torque, and a mechanical sub-model to yield the rotor speed. In addition, a stator current output sub-model is needed for calculating the voltage drop across the supply cables. Multiple line equation(s) cannot be represented in ASCII text... ASCII text where Vas, Vbs, and Vcs are the three-phase stator voltages, while Vds and Vqs are the two-axis components of the stator voltage vector Vs. Torque sub-model of induction motor In the two-axis stator reference frame, the electromagnetic T is given by:T = PLm/3(idriqs - iqrids) Mechanical sub-model of induction motor From the torque balance equations and neglecting viscous friction, the rotor speed omega0 may be obtained as follows: Multiple line equation(s) cannot be represented in ASCII text where J is the moment of inertia of the rotor and load and TL is the load torque. Stator current output sub-model The stator current output sub-model is used to calculate the stator current amplitude according to the following equation:|is| = 2/3 square root of (ie, sub ds)2 + (ie, sub qs)2 A SIMULINK Fcn' block is used to implement the above equation. Simulation System Of Induction Motor The complete simulation system of the induction motor includes the induction motor model in a power supply sub-model. Power supply sub-model The voltage supply block consists of a three-phase sinusoidal voltage generator and a terminal-voltage calculation block which accounts for the voltage drop in the supply cable. Simulation Results The induction motor chosen for the simulation studies has the following parameters: Type: three-phase, 7.5 kW, 6-pole, wye-connected, squirrel-cage induction motorRs = 0.288 OMEGA/ph Rr = 0.158 OMEGA/ph Ls = 0.0425 OMEGA/ph Lm = 0.0412 OMEGA/ph Lr = 0.0418 OMEGA/ph J = 0.4 kg m2 JL = 0.4 kg m2 To illustrate the transient operation of the induction motor, a simulation study of direct-on-line starting is demonstrated.

Poverty and Pollution - Essay Example This paper outlines that Cubatao in Brazil, which may be the most polluted area in the whole world, has about 100,000 people living in the valley. Inhabitants have refused to sell their land and resettle elsewhere because of the readily available jobs from the industries and the cheap life around. This paper will examine the ethical implications of pollution in the third world, pollution as the price for progress, moral right to human beings of a livable environment, and global pollution standards. Additionally, the paper will examine whether the wealthy nations have an obligation to provide poorer nations with resources to develop greener industries. Ethical implications of businesses polluting in a third world country are common. First, every animal, plant, and other living things have a right to a better environment. It is unfortunate that pollution destroys their habitat shortens their lives. Additionally, pollution causes the extinction of some animals resulting in an incomplete life cycle of such animals. Living things depends on one another for survival and human beings depend on them. It is unethical that a human decision can result in death and loss of livelihood. Although human beings are superior to other beings, they have an obligation to other human beings and nonhuman beings. Secondly, right to bodily security supersedes all another human right including the right to property. The health of the environment is more important than all other rights because they protect human life. Therefore, pollution is unethical as it undermines a basic human right. Some businesses may conduct operations in a third world country and disregard any standards of pollution control. To reap the benefit of cheap labor and circumvent the strict conditions of working, many companies have moved their factories to third world countries.
