William Dunham s Journey Through Genius - 1432 Words

The author of Journey through Genius, William Dunham, begins this chapter by depicting how mathematics was spurred and developed in early civilizations. Dunham focuses primarily on the works’ and achievements’ of early Egypt, Mesopotamia, and Greece in this section. These ancient societies, as they developed, produced mathematicians such as; Thales, Pythagoras, and Hippocrates, who turned a basic human intuition for space and quantity into applicable everyday mathematics. The primary influences driving the development of early mathematics were the issues of growing civilizations, most notably counting commodities, taxation, and the division of land equally, rather than a pure desire for understanding that is seen in mathematics today. These influences culminated in the development of early arithmetic and geometry. The first civilization that is discussed is early Egypt. Records have been found referring to mathematics done in Egypt showing a rudimentary understanding o f the Pythagorean Theorem as it pertains to the construction of triangles with whole number sides before the creation of the Pythagorean Theorem. An example lies in an ancient Egyptian construction of a rope with knots forming 12 evenly spaced segments along the length of the rope. They knew if a triangle having sides of 5, 4, and 3 segments was formed it would form a triangle containing a right angle. However, it is important to state that evidence has not been found that ancient Egyptians understood exactlyShow MoreRelatedStephen P. Robbins Timothy A.

The Crucible Theme Essay Research Paper Pandemonium free essay sample

The Crucible Theme Essay, Research Paper Chaos runs rampant, and suppressed kids shout out enchantress. Scenes such as these from Arthur Miller s play The Crucible, provides a fictional word picture of the ill-famed 1692 Salem, Massachusetts, enchantress tests. During the drama, the full community suffers from the mass craze that starts with a few immature misss dancing in the forests. When the misss are inflicted with unnatural unwellnesss and jobs, the community assumes that witchery is involved. After many accusals, tests, and executings, the community s crazes eventually ends. Certain characters fight their ain internal conflicts against the background of an full community in chaos. Miller uses three characters who clearly manifest this internal conflict. First, Mary Warren s whole personality turns upside down when she is lacerate between stating the truth and lasting the tests. John Proctor is the following who is forced to contemplate a pick between the importance of his household and his ain name. We will write a custom essay sample on The Crucible Theme Essay Research Paper Pandemonium or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The 3rd, Reverend Hale, battles with himself about whether or non to transport out his occupation demands or to make what he knows is right. All three characters face hard picks that are eating off at each one s scruples. Should they make what they believe is right, or what will assist them last the enchantress tests? Each character and state of affairs is alone, get downing with Mary Warren. Inner convulsion plagues a miss named Mary Warren, house retainer to the Proctors, throughout the drama. When Mary foremost appears in the beginning of the craze, the reader perceives her to be a really diffident miss who will neer talk her head. She is afraid to stand up to Abigail and state the truth about what truly happens in the forests the dark Reverend Parris catches them dancing. What happens in the forests is more than merely dancing, though. Abigail makes life menaces against all the misss involved in the dance, frightening Mary Warren. This submissive feature besides shows itself when John Proctor comes to Reverend Parris s house to state Mary to travel place and have no portion in all this bunk. As before, she is afraid to talk her head to John Proctor and responds to his orders with I m merely traveling place ( 21 ) , connoting to the reader that she is making what he wishes because she is afraid to talk her head. As the drama continues and as Abigail influences her, Mar y begins to interrupt this self-restricting cast and does what she wants in respect to the Proctors and herself. Mary Warren, along with many other misss, becomes enthralled in the ballyhoo of acquiring all the attending from the community and exerting power through initiating and stubbornly go oning these enchantress tests. When John Proctor eventually shows that when people like Rebecca Nurse and Elizabeth Proctor, who are the saintliest of people, stand accused of practising witchery that something must be incorrect, it affects Mary s function. When John inquiries Mary after her twenty-four hours as an functionary of the tribunal, she tells him she [ Goody Osborne ] tried to kill me many times ( 57 ) . After stating this, Mary so realizes that her whole mentality on life bases on unfairness and faces a hard determination. This proves true when she begins sobbing and calls out in guilt, Goody Osburn- will hang! ( 56 ) . Reluctantly, she must make up ones mind how she can untangle herself from Abigail and all her friends, non to advert her new feelings of assurance. Mary decides to talk out against Abigail and the others for their false accusals after John Proctor threatens her. Yet, as Mary does this heroic act of get the better ofing her old world, Abigail pretends that Mary is besides a enchantress, ironically utilizing the same cramp of tantrums that Mary uses during the tests to convict so many others ( 108 ) . Mary now faces yet another grueling internal struggle. Should she make what she knows is right and likely dice for it or return to her old ways? Mary eventually succumbs to Abigail s hypnosis and accuses John Proctor of coercing her to lie. Clearly, the conflict that Mary Warren faces from the really beginning is tremendous. She must cover with the determination of life and decease. She has the pick to state the truth and dice, or to lie and populate. This determination is similar to the agonizing internal struggle that John Proctor suffers throughout the drama. John Proctor, like Mary Warren, besides faces interior convulsion. A husbandman and small town common man in Salem, John commits criminal conversation with Abigail and has perfectly no purposes of fall ining the enchantress test unless his pregnant married woman should besides go involved. This involuntariness in John to fall in the tribunal proceedings shows when his married woman attempts to convert him to travel to the tribunal and allow them cognize Abigail is a fraud. He loftily tells her, I ll think on it ( 53 ) . After his married woman becomes involved, John can non accept the fact that she may decease for his wickedness of criminal conversation so that Abigail may be pacified. John is an unsloped and dignified adult male and because of these features, he believes at foremost he can non hang and decease a sufferer for his God when he has this wickedness of criminal conversation looming over him every waking minute. John subsequently says to Elizabeth when they discuss what he is traveling to make about the accusals made against him that, My honestness is broke, Elizabeth ; I am no good adult male. Nothing s spoiled by giving them this prevarication that were non rotten long earlier ( 136 ) . John eventually reaches the critical determination to squeal to hex trade and unrecorded, instead than decease for something he has non done. Even though, John confesses, he does non let Danforth to officially document it. When Danforth asks him why, John calls, Because it is my name! Because I can non hold another in my life How may I live without my name? I have given you my psyche ; go forth me my name! ( 143 ) . John feels strongly about holding a good name and non deceasing with a dirty name. John weighs both sides of his internal struggle and realizes that he must non do another error. He, hence, sentences himself to decease, non for his ain interest, but instead for the interest of others. As John dies, Elizabeth weeps stating, He hold his goodness now. God forbid I take it from him! ( 145 ) . When Elizabeth says this, it proves that John is a dignified and unsloped adult male who tries to happen a manner to get away his wickedness of criminal conversation which causes him internal struggle. The grounds shows that throughout the drama John still feels guilty about Abigail and feels responsible for his married woman s strong belief of being a enchantress. By leting himself to hang without confession, he allows himself to derive peace by go forthing his household with a good name. Almost everyone in the community feels some type of duty that connects to the strong belief of some of the occupants of Salem. This internal struggle is apparent in Reverend Hale whose probe causes these jobs to leap from merely dancing in the forests to witchcraft. At first, Reverend Hale is certain about his belief that there are enchantresss in Salem and feels that he needs to transport out the desires of God himself. Yet, as the drama moves on and Hale sees all these honest and up-standing people being sentenced and executed, he besides feels an interior struggle. He contemplates whether to make what he is sent to make, listen to Danforth, or listen to his ain scruples and denounce these proceedings as unfair and incorrect. Hale decides to help all the people wrongly accused by promoting them to squeal and salvage themselves from these false proceedings. Hale, trying to atone his ain wickednesss by seeking to do people confess provinces, I come to make the Satan s work. I come to advocate Christians they should contradict themselves can you non see the blood on my caput! ! ( 131 ) . This shows that he is experiencing the effects of his interior struggle because he is seeking to decrease the feelings of guilt he is sing. Hale overcomes his convulsion by following the truth he knows in his bosom to be right. Yet, he is reding people to predominate upon your hubby to squeal ( 132 ) and says, God damns a prevaricator less than he that throws his life off for pride ( 132 ) . He besides convinces people to lie, which is against his faith and considered a moral wickedness. However, he decides that earthly life is a greater gift than ageless life. Reverend Hale faces with many hard determinations. The determinations of Reverend Hale are similar to many people s determinations. Everybody throughout his life may confront interior struggles. Although the interior struggles of today are nil like what Mary Warren, John Proctor, and Reverend Hale face during this drama, they are forced to do a determination based on what they think is right and true. Should they allow guiltless people die to salvage themselves, or should they let their ain persecution by denouncing the proceedings and perchance hold a opportunity of salvaging some of the inexperienced person, is the inquiry they must inquire themselves. These three characters likely face the most hard determination they have of all time made in their lives. They must weigh their picks carefully and make up ones mind where they stand. Deciding where they stand is non as easy of a undertaking, as it may look. Mary Warren who feels burdened with this truth and cognition but is scared of what might go on if she speaks. Ultimately, she comes to the determination to take life with convulsion over decease. This is besides seen in John Proctor who is forced to take between his good name that accompanies decease or a life with sorrow and convulsion. He decides that he would instead decease a immature adult male with a good name than an old adult male with a dirty name. Similarly, Reverend Hale must do a determination between interior life convulsion with the alleviation of assisting some inexperienced person or the pick of decease knowing that he has aided this craze in forming. He, like John Proctor, besides chooses the alleviation from his interior struggle, although his is the easier self-relief of the two, since he must merely advocate Christians while John will hang. Whether right or incorrect in his determination, each character carefully weighs his pick and goes with what he thinks is the right determination within his life and must populate and decease by that determination, deciding whether good or bad, the struggle.

The idea of travelling through space, even living Essays

The idea of travelling through space, even living Essays The idea of travelling through space, even living and working on other planets, has fascinated people for centuries. Despite numerous setbacks and daunting expenditures, travelling in the outer space has never failed to attract people's attention and provoke controversy. Sixty years after the first Moon landing, people question whether the feat, previously thought of as a giant leap for mankind, has substantially benefited people's lives. In my opinion, landing on the Moon has enormous relevance for the quality of life, albeit not always explicit.The first implication of Moon landing is reflected in the likelihood of travelling on other planets. Moon, as the object in the outer space closet to the Earth, can serve as a launch site for the journeys to other planets. Having no atmosphere, the Moon is a permanent base for people to observe the universe easily and provide them with sufficient evidence they require for decision making on a great many significant issues, which are likely t o have direct impact on them. For example, one can learn more about the treat of potentially hazardous objects that are Likely to hit the Earth and destroy our civilization.Another remarkable breakthrough made by the Moon landing is that it reignites people's enthusiasm in the natural sciences. When today's youths become increasingly interested in such subjects as commerce, finance and business, space exploration successfully attracts and retains talents in space-related technologies. These young minds are convinced that travelling the unknown of the universe is feasible despite many challenges. They are inspired to think for the future, instead of being preoccupied with contemporary issues only.It should also be noted that the Moon has water, the basic resource for people's survival, and it abounds in solar energy, a clean and readily obtainable resource. It is also believed that minerals are plentiful there to be exploited. Some day, if people are forced to move off the Earth, the Moon might be the best shelter. Although people have not yet fully explored this possibility at this stage, preliminary investigation is imperative.Based on the above-mentioned facts, one can conclude that the Moon landing greatly impacts on distant future, although its effect is not apparent for the time being. The Moon is the eventual gateway to other planets and potentially the place of residence for the future generations. The scientific knowledge and economic benefits to be gained by building a sustainable Moon base are huge.

Describe with Examples How Different Aspects of Development Affect One Another Essay Essays Describe with Examples How Different Aspects of Development Affect One Another Essay Essay Describe with Examples How Different Aspects of Development Affect One Another Essay Essay Question:Describe with illustrations how different facets of development affect one another. Answer: When turning up kids learn many things and at times these can overlap and go intertwined with each other. I have wrote a brief description of these different facets of development and what they mean in general footings: Behaviours – The manner in which one acts or conducts oneself. particularly towards others. Communication – The conveyance or exchanging of information by talking. composing. or utilizing body linguistic communication. Emotional – The feelings and/or reactions of an individual’s fortunes. temper. or relationship with others. Intellectual – The module of concluding and apprehension. Language – The method of communicating. i. e. written or spoken. which has been structured to be understood. Physical – Relates to the organic structure and non the head. Social – Relates to how one works in partnership with others and the demand for company and communicating. Example: When my girl was a babe. she learned that the things she did prompted different reactions from her pa and I. such as smiling when she smiled. and coming to her when she cried. In this manner she was get downing to larn that physical Acts of the Apostless. are a method of pass oning and a manner of showing emotion’s such as felicity and unhappiness. Through this she gained the mind to understand that shouting agencies she is sad and as she got older she came to understand that other people are sad when they cry excessively. The more contact she has had with people. the more her ain societal assurance has expanded and as such she will now travel to household members and seek to pass on and acquire positive reactions through her good behavior such as clapping her custodies when happy. She is now a twelvemonth old and trying to larn what words are and what they mean. as she has observed that this is how adults communicate through spoken linguistic communication. I have used my girl as an illustration to demo how different facets of development affect each other and can happen at about the same clip. If we hadn’t smiled back at her when she smiled. she may non hold attached this physical motion as an look of her emotion’s. which would hold impacted her ability to socialize with others and sympathize with their emotion’s every bit good as communicate her ain. In small ways such as that. each facet of development can impact each other and as these chief phases of development continue to impact kids as they learn and grow. it finally affects the individual the kid will go. Children are influenced by those around them such as parents. friends and instructors who the kids will emulate and larn from through observation and so put into pattern in their ain societal brushs.

How was picture production affected by the rise of the city of Edo Essay

How was picture production affected by the rise of the city of Edo - Essay Example Edo culture saw the living side by side of both the rich and poor in Japanese society. This gave rise to a different point view in interpreting nature which with the combination of the principles taught in Zen Buddhism gave rise to the aesthetic values which characterized Japanese art. These values of suggestion, irregularity, simplicity and perishability, as Donald Keene identified them. Suggestion or yugen is the characteristic wherein the artist suggests a hint of nature. There is no idealization of the subject but connotes a suggestion of what it is in relation to what it truly is. The artwork gives an indication of reality and does not capture the subject in its real form. Zen Buddhism influence is reflected in Japanese aesthetics through austerity and simplicity in presentation. Perishability captures the very essence of life and nature, showing the impermanence and sadness that pervades its reality. All these elements are brought to together to constitute the Japanese measure of aesthetics in all its art forms, from painting, literature, architecture, pottery, to wood block prints. Even the tea ceremony as a Buddhist ritual is influenced by the tenets of these aesthetic building blocks which form Japanese culture. Edo culture had a great influence in the development and adoption of these aesthetic cornerstones. A great fire suffered by the city brought about the popularity of wood print blocks or ukiyo-e. Ukiyo-e in general is the stylized school in Japanese painting especially prints using colored wood blocks. Ukiyo-e gained popularity as an affordable means of acquiring art, especially among the middle class population of Edo. The Ukiyo-e style was described as a â€Å"floating world† because it describes the instability of common people’s lives. It often portrayed ordinary people, actors, courtesans, vendors, and the like. A woodblock print by Kuryosai Isoda depict a â€Å"kamuro† or courtesan in the middle of two other

How Has Being a Christian Affected the Life Essay

How Has Being a Christian Affected the Life - Essay Example The researcher states that until he was about 12 years-old that he began to understand why the pilgrimage to church each week was important to his parents and soon after, what had been a mindless and somewhat boring routine became important to him.   Maybe it was because the author was a little bored in church and the Bible was the only reading material available but regardless of the motivations, he started his own routine of reading the red-letter parts of the New Testament each Sunday. Entranced by the words of Jesus, this habit progressed to late evenings at home and even on the bus to school. The researcher found the words of Christ simple, to the point and ultimately a path to inner contentment and happiness. His words are, essentially, a guidebook for life. It was during this period in the author’s life, early teenage years, that the spirit of God entered his life through the words of His Son and this connection has grown stronger by the year. The researcher made the transition from attending church as a matter of custom to being a devoted Christian gradually throughout the middle-school years; a time when having faith is certainly a benefit. Though the author knew it wasn’t uncommon for everyone to have feelings of awkwardness at this age, this knowledge did not help soothe his own feelings of inadequacy. The researcher wasn’t considered one of the cool, popular kids and neither were 99 percent of the students but again, this mathematical fact did not help either. Most of the author’s friends from church attended other schools and the couple of people he associated with in elementary school had different class schedules. The researcher felt very alone, vulnerable and intimidated. The ‘other’ students seemed more mature and sure of themselves which was more a result of his distorted self-perception than a reality nevertheless this feeling was very real at that time. The researcher did not feel comfortable tellin g anyone close to him such as his parents or his once-a-week friends from church so the author took solace in prayer. It gave him inner-strength in a time of self-doubt and confusion. Reading the Bible also helped considerably. Besides the lessons and wisdom gained from its pages, the realization that Jesus was not a popular figure either and had also a small circle of friends was of some comfort. Being a Christian at this time of great uncertainty was very beneficial.   It gave the author something solid in his life to hold on to at a time when he needed it the most.  

Electricity Generation Using a Wind Turbine Essay Example for Free

Electricity Generation Using a Wind Turbine Essay Wind turbines are machines built for generation of electricity. The electric power is generated by harnessing the wind speed to drive the shaft that connects to the gears assembled to amplify the amount of energy produced. Aside from wind power, other forces, like gravity and thermal energy, also affect the rotation of the blades, which in turn affect the electricity generation process. This research is aimed at creating a simple wind turbine that is capable of generating electricity. The process will be explained using the principles found in physics such as the law of gravity, electromagnetism, thermodynamics, and momentum. Materials and Method The wind turbine setup was created using these devices: hub, three fan blades, metal box, two sets of gears, copper wire, a permanent magnet and volt meter, two rods of different sizes and couple heat sinks. These devices were then assembled to a working wind turbine. First, the blades were attached at an angle of 20 degrees. Then the gears were connected to the metal hub. The gears were then connected to a permanent magnet that was used to generate the electricity. The magnet was coiled with 80 turns of copper wire (about ? inch) for generation of power. It was then spooled to a steel block which helped increase the voltage just like a transformer. Greased bushing was also set up between the two gears and the hub. The perforated cylindrical block was placed on both rods to serve as a heat sink. The second rod was bent at the tip to change cyclic motion to vertical motion to the magnet. Finally, the wind turbine was mounted on a 10 feet tall support above ground level and was observed. Discussion The wind turbine was observed to see how it can generate electricity or if it can. As the wind blew on the blades, they turned along with the shaft. The shaft was connected to the gears that were also connected to the permanent magnet. When the magnet moved, the volt meter needle deflected which meant it detected electric power from the wind turbine. The wind turbine was successfully set up and generated electricity. The process of converting wind energy into electric energy can be explained using some of the principles in physics: law of gravity, electricity and magnetism, thermodynamics, and momentum. While the whole setup depends on wind movements, other types of forces also affect the generation of electricity such as gravity and friction. Newton’s first law of motion states that â€Å"an object at rest will remain at rest while an object in motion will remain in motion. † This is also called the Law of Inertia or the resistance of an object to change its state of motion. Mass, being the property of matter, is used to measure the amount of inertia. This mass also causes gravitational field; the bigger the mass, the stronger the field. Consequently, in the presence of another object of different mass, their gravitation forces affect one another, that is, they attract one another. Earth is an example and the assembled turbine fan is the other object. Since the fan has smaller mass than the earth, it tends to fall to the earth or that the earth pulls it down. The force of attraction between earth and gravity is computed as mass multiplied by acceleration due to gravity (Wfan = mg); the result of which is also the weight of the fan. This concept can be used to explain why the turbine fan turns when the wind blows on it. Aside from the streamlined design of the blades allowing smooth air flow, the ‘pull’ force of gravity also helps the fan turn on its place or as long as it is mounted to the support. Next is electricity and magnetism. When the fan turned, the gears connected to the magnet also turned. We know from Hans Christian Orsted that electricity goes together with magnetism putting sense to the term electromagnetism. Electric wires do have magnetic properties and magnets also have electrical properties. This is can be shown in the wind turbine setup. The general principle in producing electricity using magnets and coils of wires is called electromagnetic induction. Faraday developed the law of electromagnetic induction stating that â€Å"the induced electromotive force in a closed loop is directly proportional to the time rate of change of magnetic flux through the loop. We already know that magnetic flux is the measure of quantity of magnetism considering the strength and extent of the magnetic field. Thus, the magnetic field of the permanent magnet and the rotating motion generates electricity. This explains how kinetic energy from the wind is converted to electric energy. However, not all of the kinetic energy from the wind movement is converted to electric energy. In other terms, the kinetic energy is not conserved. This is basically due to friction. Friction is not a conservative force. By saying conservative, we mean it can be converted to other forms without losing portions of the original amount. An example is the gravitational force. Any object that falls from a certain height above the ground with initial potential energy (PE) converts all of it to kinetic energy (KE) as it reaches down the level. Same with when the object goes up. The original amount of KE is totally converted to PE. Friction does not behave this way. For example, the initial energy of a pusher pushing a box one meter away cannot regain the energy consumed even if the box is returned to its initial position. This is due to friction. What happened to the lost energy? They all go as heat energy, that is, wasted energy. In the wind turbine, change in the temperature is observable, especially in the gears and the rods. This is because they are all in contact while utilizing the wind power to move. Because of friction, the gears and the rods will heat up in the long run. It can damage the setup, starting from the parts with intense friction. In order to counter this, a heat sink has to be installed. Conclusion The wind turbine was successfully assembled and electricity was produced. The electric energy was converted from kinetic energy derived from the wind movement. When the blades turn, the rods connected to the mechanism turned and by magnetic induction, electricity was produced. Wind power is then a good source of kinetic energy needed for generating electricity. I suggest we put up wind turbines to harness the kinetic energy of the wind. It can help minimize the cost of power generation and we can also avoid the adverse environmental effects of using petroleum products.

When the story begins Holden at age sixteen, due to his poor grades is kicked out of Pencey Prep, a boys’ school in Pennsylvania. This being the third school he has been expelled from, he is in no hurry to face his parents. Holden travels to New York for several days to cope with his disappointments. As James Lundquist explains, â€Å"Holden is so full of despair and loneliness that he is literally nauseated most of the time.† In this novel, Holden, a lonely and confused teenager, attempts to find love and direction in his life. Holden’s story is realistic because many adolescent’s face similar challenges.   Ã‚  Ã‚  Ã‚  Ã‚  J.D. Salinger presents Holden Caulfield as a confused and distressed adolescent. Holden is a normal teenager who needs to find a sense of belonging. All though Holden’s obsession with â€Å"phonies† overpowers him. Dan Wakefield comments, â€Å"The things that Holden finds so deeply repulsive are things he calls â€Å"phony†- and the â€Å"phoniness† in every instance is the absence of love, and , often the substitution of pretense for love.† Holden was expelled from Pencey Prep School not because he is stupid, but because he just is not interested. His attitude toward Pencey is everyone there is a phony. Pencey makes Holden feel lonely and isolated because he had very few friends. Holden’s feeling of alienation is seen when he doesn’t attend the biggest football game of the year. His comments on the game: â€Å"It was the last game of the year and you were supposed to commit suicide or something if old Pencey didn ’t win† (2, Ch. 1). This also hints to Holden’s obsession with death. Holden can’t find a since of belonging in the school because of all the so-called phonies. Holden speaks of Pencey’s headmaster as being a phony. Holden says that on visitation day the headmaster will pay no attention to the corny-looking parents. Holden portrays his not being interested by saying, â€Å"all you do is study so that you can learn enough to be smart enough to buy a goddam Cadillac someday, and you have to keep making believe you give a damn if the football team loses†(131, Ch. 17). Holden does not care for school or money. He just wants everyone to be sincere and honest. Holden's obsession with phonies causes him to have no positive adult role models to follow.

“Tyronian” Tragedy

In Eugene O'Neill's agonizingly autobiographical play Long Day's Journey into Night, readers are introduced a dismal family situation. Drugs, death, illness and failure lace each conversation, and regret flows almost as unreservedly as the alcohol. In such a tragedy, one would expect to have a clear idea of with whom the blame lies. In this piece of drama, however, there is a distinct inability to do so. Eugene O'Neill persistently manipulates the emotional responses of the reader. This manipulation keeps partiality off balance and uncertain. O'Neill accomplishes this by allowing readers to sympathize with one family member. Once sympathy is established for one particular character, that character promptly says, or does, something that loses the reader's alliance, along with the alliance of whichever character he or she is berating at that particular moment. This results in the reader's inability to discern who, precisely, is culpable for the Tyrone family's situation. The idea of assigning culpability in Long Day's Journey Into Night is almost humourous. Even if one wanted to, it would be difficult to sort through years of built up anger, layer upon layer of repression, and huge amounts of guilt in each character; for each character is at fault for one thing or another, and, in addition, each character blames someone else for his or her problem. For example, Mary blames her husband and his tightfistedness for her addiction to morphine. Due to their mother being an addict, Jamie is unable to bring girls home, thus he visits prostitutes. Such behavior has influenced his younger brother Edmund, â€Å"making him old before his time† (35). Consequently, Jamie is at fault for Edmund's poor health. In turn, his mother, for causing the addiction by being brought into the world, as well as worsening it with his own illness, blames Edmund. And so, the vicious circle continues. However, if one does not wish to inflict upon one's distinguished teaching assistant a painfully long dissertation of each member's contributions to the tragedy and the results thereof, one ought to maintain, for argument's sake, that the majority of the culpability lies with James Tyrone, for his behaviour in regards to money, alcohol, and his own status as a failed actor. James's father had left the family when James was only ten years of age. This left James as the man of the family, working twelve hours each day to help provide for his mother and three sisters. As James explains, â€Å"It was in those days I learned to be a miser†(151). He feels proud of his savings, and announces to his family in regards to buying something: â€Å"I got them dead cheap†(15). His own early recognition of the importance of money explains his continual contempt for his own children's lack of concern when it comes to working: â€Å"What do you know of the value of a dollar? (150). He accuses Jamie of being lazy and having no ambition. Not only does James Tyrone wish his sons understood the value of money, but since they do not, he is forced to be miserly enough for the whole family. Consequently, the family resents his overly economic ways. There are many attacks throughout the play on James Tyrone for this, the first one being Jamie accusing him of not sending Edmund to a real doctor for his illness when he first got sick. Jamie says, â€Å"Hardy only charges a dollar. That's what makes you think he's a fine doctor! â€Å"(31). Later, another dialogue gives an even worse view of the situation; Tyrone sending Edmund to a cheap sanatorium, but spending money on real estate: JAMIE: Well, for God's sake, pick out a good place and not some cheap dump! TYRONE: (Stung) I'll send him wherever Hardy thinks best! JAMIE: Well, don't give Hardy your old over-the-hills-to-the-poorhouse song about taxes and mortgages. TYRONE: I'm no millionaire who can throw money away! Why shouldn't I tell Hardy the truth? JAMIE: Because he'll think you want him to pick a cheap dump, and because he'll now it isn't the truth i especially if he hears afterwards you've seen McGuire and let that flannel-mouth, gold-brick merchant sting you with another piece of bum property! (82) Later realizing the anger this statement comes from, James Tyrone offers Edmund â€Å"any place you like! Never mind what it costs! Any place I can afford. Any place you like†. Sadly, there follows the stipulation Tyrone cannot seem to shake off: â€Å"Within reason. â€Å"(151). Cheap medical care seems to be Tyrone's weakness. As Mary Tyrone makes clear, his tightfisted ways result, though inadvertently, in her downfall as well, due to a doctor giving her morphine as an easy fix. â€Å"But bearing Edmund was the last straw. I was so sick afterwards, and that ignorant quack of a cheap hotel doctor-All he knew was I was in pain. It was easy for him to stop the pain. â€Å"(90) Tyrone is also to blame for his wife's general unhappiness, not just her addiction to morphine. Mary says to Edmund that she has never been happy in the house, because â€Å"Everything was done in the cheapest way. Your father would never spend the money to make it right. (45). The subsequent scene has Mary come downstairs (60), in a detached sort of manner. She complains bitterly to Edmund about Tyrone's inability to make a real home. He is too stingy to build a real home, with good servants, and so she has suffered all her life. When Tyrone himself comes in, she says in continuation of her previous statements † I'm sick and tired of pretending this is a home! You won't help me! â€Å"(69). She goes on to say that had he remained a bachelor â€Å"Then nothing would have happened. † This indicates strongly that she blames him too. Tyrone condemns Mary for her addiction, yet feels no guilt or responsibility for it, taking away any amount of forgiveness readers may have parted with in Tyrone's favour. The amusing part of this however, is while he condemns his wife for substance abuse, the same thing is his own major vice. Mary tells her husband: † I would never have married you if I'd known you drank so much† (115). She also launches into a story about their honeymoon, when Tyrone was dragged home intoxicated. It appears that in a fashion similar to that of their father, Jamie and Edmund seem quite partial to alcohol. In fact, the entire family seems unable to confront reality without chemical assistance. Mary's words indicate that drinking all day is a common Tyrone family activity: â€Å"I know what to expect. You will be drunk tonight. Well, it won't be the first time, will it i or the thousandth? † (72). The Tyrone men validate their drinking habits with folk wisdom about whiskey's alleged health benefits: â€Å"It's before a meal and I've always found that good whiskey, taken in moderation as an appetizer, is the best of tonics† (68). Alcohol has contributed to Jamie's failures. It has hurt Edmund's health. And it becomes a source of conflict between Jamie and Tyrone, as Jamie consistently steals his father's whiskey, replacing the amount taken with water, so his father won't take notice. Regrettably, the alcohol solves no problems, and problems get more intricate as the tongues loosen from the booze. The three men share a drink, but none of the social magic of alcohol seems to work. Tyrone, Edmund and Jamie remain as miserable as ever. The last, most driving element of James Tyrone's guilt is his status as a failed actor. In act four of the play, James Tyrone relates something to his youngest son that he has never told anyone before. He explains that since his father left the family when he was ten, he grew up to be miserly. Thus he was quick to give up artistic fulfillment in exchange for financial security, ruining his career as † one of the three or four young actors with the greatest artistic promise in America†(153). James Tyrone now muses that he doesn't even know what it was he had wanted to buy. It appears that James has never forgiven himself for this, and therefore inflicts it on his family and neighbours. Mary says in regards to the neighbours: â€Å"they bowed to your father and he bowed back as if he were taking a curtain call†(44). Jamie relates that Tyrone puts on an act for everybody (57). Tyrone begins to quote a play almost as tragic as his own family life, but his son, obviously well versed in his father's repertoire of chastisements from King Lear, finishes the sentence before his father can continue, with † ‘to have a thankless child'. I know†(92). His sons also immediately think in terms of tragedy when referring to their father, quoting Othello in reference to James's snoring: † ‘The Moor, I know his trumpet'†(21). It appears that Tyrone turns his own life into a tragedy, like the ones he once portrayed so well upon the stage, switching affections and emotions like he would have to between scenes, although his family isn't as accepting of this as Edwin Booth and the critics obviously were. But why bother to deal with the question of fault? After all, the characters themselves claim not to care about it, such as in act two, scene two, when James Tyrone tries to blame Edmund's consumptive state on Mary's side of the family. Jamie cries out against blame: â€Å"Who gives a damn about that part of it! â€Å"

Stefan’s Diaries: Origins Chapter 22

The week of the Founders Ball came with a cold spell that settled into Mystic Falls and refused to leave. Ladies walked around town in midafternoon in wool coats and shawls, and the evenings were cloudy and starless. Out in the field, workers fretted about an early frost. Still, that didn't stop people from as far away as Atlanta coming into town for the ball. The boarding-house was full, and the entire town had a carnival-like air in the days leading up to the event. Damon was back at Veritas, his mysterious tenure with the brigade over. I hadn't told him that Katherine and I were attending the Founders Ball, and he hadn't asked. Instead, I'd busied myself with work, feeling renewed vigor about taking over Veritas. I wanted to prove to Father that I was serious about the estate and about growing up and assuming my place in the world. He'd been giving me more responsibility, allowing me to look over the ledgers and even encouraging me to go to Richmond with Robert to attend a livestock auction. I could see my life, ten years from now. I'd run Veritas, and Katherine would run the inside of the home, hosting parties and playing the occasional card game at night with Father. The night of the ball, Alfred knocked on my door. â€Å"Sir? Do you require any assistance?† he asked as I swung the door open. I glanced at my reflection in the mirror. I was dressed in a black long-tailed coat and tie, with my hair slicked back. I looked older, more confident. Alfred followed my gaze. â€Å"Looking smart, sir,† he allowed. â€Å"Thank you. I'm ready,† I said, my heart fluttering in excitement. Last night, Katherine had teased me mercilessly, not giving me any clues as to what she was going to wear. I couldn't wait to see her. I knew she'd be the most beautiful girl at the ball. More important, she was mine. I headed down the stairs, relieved that Damon was nowhere to be found. I wondered whether he was attending the Founders Ball with some of his army friends or perhaps one of the town's girls. He'd been distant lately, impossible to find in the morning and at the tavern at night. Outside, the horses were pawing at the drive. I entered the waiting coach, which clip-clopped its way to the carriage house. I glanced out the window, and noticed Katherine and Emily standing at the front door. Emily wore a simple black silk dress, but Katherine †¦ I had to press my back into the carriage seat to keep from jumping out of the moving coach. Her dress was emerald green, nipping in at the waist dress was emerald green, nipping in at the waist before flowing over her hips. The bodice was low and tight and showed off her creamy white skin, and her hair was pulled back on the top of her head, exposing her graceful, swan-like neck. The second Alfred pulled back on the horses' reins, I opened the door of the coach and hopped out, smiling broadly as Katherine's eyes caught mine. â€Å"Stefan!† Katherine breathed, lifting her skirts slightly as she glided down the stairs. â€Å"Katherine.† I gently kissed her cheek before I offered my arm to her. Together, we turned and walked toward the carriage, where Alfred stood with the door open. The road to Mystic Falls was filled with unfamiliar coaches of all shapes and sizes, leading to the Lockwood mansion on the far end of town. I felt a thrill of anticipation. This was the first time I'd ever escorted a girl to the Founders Ball. In all previous years, I'd spent most of the evenings playing poker with my friends. Invariably some sort of disaster happened. Last year, Matthew Hartnett had gotten drunk on whiskey and had accidentally unhitched the horses from his parents' coach, and two years ago, Nathan Layman had gotten into a fistfight with Grant Vanderbilt, and both ended up with broken noses. We slowly made our way up to the mansion, finally reaching the front walk. Alfred stopped the horses and let us out. I laced my fingers with Katherine's, and together we walked through the open doors of the mansion and headed toward the dining room. The high-ceilinged room had been cleared of all furniture, and the candlelight lent a warm, mysterious glow to the walls. A band in the corner played Irish reels, and couples were already beginning to dance, even though the night was young. I squeezed Katherine's hand, and she smiled up at me. â€Å"Stefan!† I whirled around and saw Mr. and Mrs. Cartwright. I dropped Katherine's hand immediately. Mrs. Cartwright's eyes were red, and she was positively gaunt compared to the last time I saw her. Meanwhile, Mr. Cartwright seemed to have aged ten years. His hair was snow-white, and he was walking with the aid of a cane. Both wore purple sprigs of vervain–a tuft stuck out of Mr. Cartwright's breast pocket, and the flowers were woven into Mrs. Cartwright's hat–but other than that, they were clad entirely in black, for mourning. â€Å"Mr. and Mrs. Cartwright,† I said, my stomach clenching with guilt. In truth, I'd nearly forgotten that Rosalyn and I had been engaged. â€Å"It's good to see you.† â€Å"Y could have seen us sooner if you'd come ou to call on us,† Mr. Cartwright said. He could barely hide the contempt in his voice when his gaze landed on Katherine. â€Å"But I understand you must have been in deep †¦ grief as well.† â€Å"I will come now that I know you're taking visitors,† I said lamely, tugging at my collar, which suddenly felt quite tight around my neck. â€Å"No need,† Mrs. Cartwright said icily as she reached into her sleeve to pull out a handkerchief. Katherine clasped Mrs. Cartwright's hand. Mrs. Cartwright looked down, an expression of shock on her face. A wave of apprehension ran through me, and I fought the urge to step between them and shield Katherine from their anger. But then Katherine smiled, and amazingly, both Cartwrights smiled back. â€Å"Mr. and Mrs. Cartwright, I am so sorry for your loss,† she said warmly, holding their gazes. â€Å"I lost my parents during the Atlanta siege, and I know how hard it is. I didn't know Rosalyn well, but I do know she will never be forgotten.† Mrs. Cartwright blew her nose noisily, her eyes watering. â€Å"Thank you, dear,† she said reverentially. Mr. Cartwright patted his wife on the back. â€Å"Y thank you.† He turned to me, compassion es, replacing the scorn that had occupied his eyes just moments earlier. â€Å"And please take care of Stefan. I know he's suffering.† Katherine smiled as the couple rejoined the crowd. I gaped in amazement. â€Å"Did you compel them? † I asked, the word tasting bitter in my mouth. â€Å"No!† Katherine placed her hand over her heart. â€Å"That was good, old-fashioned kindness. Now, let's dance,† she said, tugging me toward the large ballroom. Luckily, the dance floor was a crush of bodies and the lighting was low, so it was almost impossible to make out specific people. Flower garlands hung from the ceiling, and the marble floor was waxed to a sheen. The air was hot and cloying, with the scent of hundreds of competing perfumes. I put my hand on Katherine's shoulders and tried to relax into the waltz. But I still felt jumpy. The conversation with the Cartwrights had stirred my conscience, making me feel vaguely disloyal to Rosalyn's memory, and to Damon. Had I betrayed him somehow by not telling him that Katherine and I were at the ball together? Was it wrong that I'd been grateful for his prolonged absences? The band stopped, and as women adjusted their dresses and grasped their partners' hands again, I headed toward the refreshment table in the corner. â€Å"Are you all right, Stefan?† Katherine asked, gliding up beside me, worry lines creasing her lovely forehead. I nodded, but I didn't break my stride. â€Å"Just thirsty,† I lied. â€Å"Me too.† Katherine stood expectantly as I ladled the dark-red punch into a crystal tumbler. I passed the glass to her and watched as she drank deeply, wondering if that was what she looked like when she drank blood. When she placed the glass on the table, she had the slightest trace of red liquid around her mouth. I couldn't help it. With my index finger I wiped the drop off the side of her bow-shaped mouth. Then I put my finger in my own mouth. It tasted sweet and tangy. â€Å"Are you sure you're all right?† Katherine asked. â€Å"I'm worried about Damon,† I confessed as I poured myself a glass of punch. â€Å"But why?† Katherine asked, genuine confusion registering on her face. â€Å"Because of you,† I said simply. Katherine took the tumbler from me and led me away from the refreshment table. â€Å"He's like a brother to me,† she said, touching my brow with her icy fingers. â€Å"I'm like his little sister. Y know ou this.† â€Å"But all those times when I was sick? When you and he were together? It seemed like †¦Ã¢â‚¬  â€Å"It seemed like I needed a friend,† Katherine said firmly. â€Å"Damon's a flirt. He doesn't want to be tied down, nor would I want to be tied to him. Y ou are my love, and Damon is my brother.† All around us, couples swirled in the semi- darkness, dipping in time to the music and laughing gaily at private jokes, seemingly without a care in the world. They, too, had to worry about attacks and the war and heartbreak, but they still laughed and danced. Why couldn't I as well? Why did I always have to doubt myself? I glanced at Katherine. A dark curl had come loose from her updo. I tucked it behind her ear, relishing the silky feel of the strands between my fingers. Longing coursed through me, and as I stared into her deep brown eyes, all feelings of guilt and unease vanished. â€Å"Shall we dance?† asked Katherine, taking my hand and pressing it to her cheek. Through the crowded dance floor, I spotted Father, Mr. Cartwright, and the rest of the Founders whispering furiously in a far corner. â€Å"No,† I whispered huskily. â€Å"Let's go home.† I grabbed Katherine's shoulder, and we whirled around the dance floor until we reached the kitchen, where servants were busily preparing refreshments. Hand in hand, we tore through the kitchen–much to the confusion of the servants –and exited at the back of the house. We sprinted into the night, oblivious to the cold air, the shrieks of laughter from the mansion, and the fact that we'd just run out on the social event of the season. The coach was tied near the Lockwoods' stable. Alfred was no doubt playing craps with the other servants. â€Å"After you, my lady,† I said, lifting Katherine by the waist and placing her in the passenger seat. I hoisted myself up to the driver's seat and cracked the whip, which immediately caused the horses to start clip-clopping in the direction of home. I grinned at Katherine. We had an entire evening of freedom in front of us, and it was intoxicating. No having to sneak into the carriage house. No skirting the servants. Just hours of uninterrupted bliss. â€Å"I love you!† I yelled, but the wind stole the words as soon as they left my mouth. I imagined them traveling with the breeze, floating through the entire world until every person in every town knew of my love. Katherine stood up in the coach, her curls whipping wildly around her face. â€Å"I love you, too!† she shouted, and then collapsed into giggles on the seat. By the time we got back to the carriage house, we were both sweaty and red-cheeked. The second we reached Katherine's chambers, I pulled the dress off her slim frame and, seized by my passion, gently ran my teeth against her neck. â€Å"What are you doing?† She stepped back and stared at me sharply. â€Å"I'm just †¦Ã¢â‚¬  What was I doing? Playacting? Trying to seem as if Katherine and I were the same? â€Å"I guess I wanted to know how you feel when you †¦Ã¢â‚¬  Katherine bit her lip. â€Å"Maybe someday you'll find out, my innocent, sweet Stefan.† She lay back on the bed, arranging her hair on the snow-white goose-down pillow. â€Å"But right now, all I want is you. â€Å" I lay down next to her, tracing the curve of her chin with my index finger as I put my lips to hers. The kiss was so soft and tender that I felt her essence and mine combine, creating a force that was larger than ourselves. We explored each other's bodies as if for the first time. In the dim light of her chambers, I was never sure where reality ended and my dreams began. There was no shame, no expectation, just passion and desire, and a sense of danger that was mysterious and beautiful and consuming. That night, I would have allowed Katherine to consume me entirely and claim me for her own. I would have gladly offered up my neck if it meant that we could have stayed locked in that embrace for all of eternity.

Web-Footed Gecko essays

Web-Footed Gecko essays The web-footed gecko is native to the Namib Desert, located on the coast of southwest Africa. Living in this location has enabled the gecko to develop many unique physical characteristics that very few, if any, other animals have. The web-footed gecko also has developed a certain way of hunting for food, as well as a way of deterring predators if it feels it may become food. This gecko has also formed breeding methods particular to the region. This five-inch translucent lizard is native to the Namib Desert of southwest Africa. This region receives virtually no rain as the land is composed of bare rock and sand, although during the nights fog rolls in from the Atlantic, cooling the sand dunes. The gecko depends on this moisture to survive, as the geckos thin skin allows it to absorb moisture right out of the air. This reptile burrows during the day to avoid the extreme heat of the desert sun because the sand remains at a constant temperature just a few inches below the surface. Due to the harsh heat of the Namib the gecko has evolved into a nocturnal animal. Its name has derived from its feet, which resemble that of snowshoes in function, and a ducks feet in appearance. This gecko has the scientific nomenclature of Palmatogecko rangei. This name is significant as it shows its relationship to other geckos through its genus name Palmatogecko. The web-footed gecko is classified as follows: Kingdom: Animalia The web-footed gecko is a predator as it has a developed sense of sight. The geckos eyes have adapted to its environment to be more functional than most would expect. The lizards pupils narrow to very small slits in daylight only to transform into very large disks at night to absorb all the light possible. Although the gecko has good visibility, ...

International Business - Essay Example Factors that have aided the manufacturing business in China First, in order to achieve economic sustainability, the Chinese economy was transformed by various regimes from a mass market for western goods and services, to a supplier of cheap goods, materials, and labour, thus beating much of the global competition from many other countries. An example is the setting up of Honda car manufacturing plant in the northern eastern China. Secondly, the Deng Xiaoping political and economic reforms created rooms for development of liberal market business in an environment of well-controlled cheap labour, spurring rapid economic growth.

This model has proven successful in the rapid economic growth of China. ... Challenges facing the manufacturing business in China First, the Chinese economy has been relying heavily on agricultural subsistence sectors to feed its population, a factor that made its economy almost to crumble in 1960 due to crop failure.

Letter from Mahavira Essay Example | Topics and Well Written Essays - 750 words

Letter from Mahavira - Essay Example By enduring all sorts of calamities, I was given this name Mahavira, which means great hero or brave and courageous. You have to learn how to conquer your desires and feelings, not be conquered by them. The only way to liberate yourself from all the pain is learning about the right faith (samyak-darshana), right knowledge (samyak-jnana), and right conduct (samyak-charitra). This last is based on the five vows. Do you remember the five great vows Nonviolence (Ahimsa)-do not harm any living being; Truthfulness (Satya)-to speak only the truth; Non-stealing (Asteya)- do not take anything that was not given to you; Chastity (Brahmacharya)-do not indulge in sexual pleasure; Non-possession/Non-attachment (Aparigraha)- to detach from any material possession. These five principles will help you achieve the blissful state. But you need to detach completely from people, places, and material things. That is why I spent twelve years of my life in silence and deep meditation. Sometimes, I spent days without eating, I had no place to live or clothes to wear, but I achieved Kevalnyan, enlightenment. When I learned this ultimate truth I decided to travel around India and share this knowledge. Be careful with all the living beings, if you harm them, you will be harming yourself. If you take something that was not given to you, it would be like stealing to yourself. Indulging in sensual or materialistic passion will only lead to vices like greed, lust, hatred and anger. These feelings are all violent and destructive; they can lead you to kill. Your karma will accumulate. If you wish to become a monk, you will have to follow your vows strictly. Monks and nuns will have to be very strict about following the Jain philosophy. Everyone can achieve the ultimate happiness; I do not make distinction between men, women, rich or poor. I divide my followers in what is called a four-fold order: monk (Sadhu), nun (Sadhvi), layman (Shravak), and laywoman (Shravika). I believe that the theories of Anekantvada and Syadvada, explain the relativity in the world. The world has an infinity of view points depending on the time, place, nature and state of the one who is the viewer and that which is viewed. The truth has many aspects, it depends from the points of view. What is true from one point of view may vary from another. Absolute truth cannot be obtained from any particular perspective alone. Absolute truth is the sum total of all the different-view points. Imagine for example that you have your eyes covered and that you come across a river while you walk. You step inside and the water covers up to your knees, not too deep it seemed. When you go out and uncover your eyes, you discover that you were standing up on a rock inside the river, but that the river was in fact so deep that it would cover you up to your head. The perspective changed the way in which you described the river. In order to obtain Moksha, you can follow the self-discipline methods I have preached and practiced. Some of them are: disregard of worldly objects, moral purity, meditating without moving the body, self-denial, penance, austerity, renouncing to pleasure, and freedom from karma. Meditation is very important in the life of a Jain. It helps to discipline the mind and the body. Sometimes you will remain in deep meditation in a same position for a long time, while your mind

PetMeds Transformation Case Study Example | Topics and Well Written Essays - 1000 words

PetMeds Transformation - Case Study Example The set of variables are grouped into transformational and transactional factors (Falletta, 2005). This paper focuses on the seven transactional variables, such as structure, tasks and skills, management practices, systems and policies, work unit climate, motivation and individual needs and goals. Burke-Litwin Model defines the organizational structure as an arrangement of functions and people into specific areas and levels of responsibility, decision-making authority, communication and relationships (Falletta, 2005). Such structure shall support the organization's mission, goals and strategy in order to achieve competitive advantage for the firm (Porter, 1985). PetMed Express can be considered as a mechanistic organization that follows the functional departmentalization structure. The company has highly specialized departments with high formalization and a clear chain of command. The company's structure supports its cost leadership strategy by increasing consistency and reducing cost through centralization and management control (McShane, 2001). The company currently has 248 full time employees distributed into four departments of customer care, warehouse, pharmacy and corporate departments. The customer care department consists of customer care representatives in a call center environment while the warehouse department consists of supervisors and associates. The pharmacy department employs pharmacists, pharmacy technicians and support. The corporate department is composed of accounting, legal, marketing, information technology, purchasing and human resources. Below is the organizational diagram of PetMed. (PetMed Express, 2009) Figure . PetMeds Organizational Chart In order to be effective in serving the customers demand, PetMeds employed 143 people in customer care and marketing, 58 people in pharmacy, and 34 people in warehouse and purchasing. Therefore, the structure of human resources in the company is aligned with its mission of delivering exceptional service, savings and convenience to its customers while maintaining a corporate strategy of cost advantage. Tasks and Skills and Motivation The business success of PetMed Express is attributed to the core competencies of their customer care, warehouse and pharmacy department. According to Prahalad and Hamel (1990), the core competencies of a company are the collective learning in the organization that involves communication, involvement and deep commitment to working across organizational boundaries. Therefore, the core competencies provide potential access to a wide variety of markets and make a significant contribution to the customer benefits of its products. The Burke-Litwin Model describes tasks and skills as the behavior required for task effectiveness which includes specific skills and knowledge required to accomplish work (Falletta, 2005). The tasks and skills of an individual coupled with its motivation, or heightened behavior to achieve goals, have a significant impact on organizational performance and productivity. In other words, an empowered and motivated employee will perform its duties and responsibilities when his tasks and skills are matched with the job requirements. The human resource management has an extensive recruitment and selection strategy that identifies the needs of the job as well as the competency of the employee. The bulk of the

Moliere’s Portrayal of Religion and Religiosity Essay Example for Free

Moliere’s Portrayal of Religion and Religiosity Essay Moliere’s Tartuffe is about a man named Tartuffe who is a beggar and holy man that was recently taken in by a Christian man named, Orgon. Tartuffe has Orgon fooled, but the entire rest of Orgon’s family sees Tartuffe as a hypocritical, self-righteous con artist. Orgon becomes obsessed with Tartuffe and would rather talk and hear about him than his own sick wife. Even though Moliere rewrote this play twice, there are many reasons that the church might still be concerned about the hypocrisy that he used toward Christianity in this play. In 1666 Tartuffe was banned, a play many found offensive because of its assault on church hypocrisy. Many people of the church could still be concerned, due to Moliere’s portrayal of Christianity and how it is almost mocked in this play. Allot of the comedy Moliere portrays is intense focus on Orgon as example of a certain kind of traditional Christian. He isn’t the ‘only’ type of Christian in this play, but the way he is portrayed is almost in a hypocritical manner. Orgon is so eager to believe Tartuffe, mainly due to the fact that Tartuffe is professing to be another type of Christian. Moliere regards the type of Christian that Tartuffe is as insane. The way mankind is portrayed on behalf of Orgon is almost as depraved as a result of Original Sin, so therefore Orgon has to be subjected, for his own good, to somewhat of a dictatorial control by divinely appointed authorities, or the King. Moliere portrays Orgon as a good Christian man, who is taken advantage of and ultimately almost loses everything because he is willing to take Tartuffe in and treat him as if he were family. The reason the church should be concerned here is the fact that Moliere portrays the way Tartuffe is insane and manipulates the good Christian man. He shows Orgon, the good Christian man as blind to all the wrong, and coming out as essentially the â€Å"loser† and the insane Christian and manipulator, Tartuffe, comes out with all of Orgon’s belongings. After reading Moliere’s Tartuffe I now can see how the church would be heavily concerned with how Moliere portrays Christianity as ‘the nice guy finishes last’ with relation to Orgon and Christianity. The church could also see the hypocrisy by the portrayal of Tartuffe as a â€Å"religious con man† or â€Å"religious fraud. †

Case Study of Dell Computer Corporation :: Business Marketing, Case Study, solution

Case Study of Dell Computer Corporation Introduction Michael Dell founded Dell Computer Corporation in 1984 with a simple vision and business concept – that personal computers can be built to order and sold directly to consumers. Michael believed his approach had two advantages: (i) by passing distributors and retail dealers eliminated the markups of resellers, and (ii) building to order greatly reduced the costs and risks associated with carrying large stocks of parts, components and finished goods. Its build-to-order and sell-direct approach proved appealing to growing numbers of customers in the mid 1990s as global PC sales rose to record level. In 1998, it was already the 3rd manufacturer in the United States with a 12% share of PC market and a nearly 6% share worldwide. The company’s fastest growing market for the past several quarters was Europe. Even during the Asia economic woes in the early 1998, Dell’s sales in Asia rose 35%. Its sales at the Internet Web site were about $5 million a day and expected to r each $1.5 billion annually by the year-end 1998. Since 1990, Dell’s stock price had exploded from 23 cents per share to $83 per share in May1998 with a 36,000% increase and was the top performing big company then. Dell’s principal products included desktop PCs, notebook computers, workstations, and servers. Its products and services were sold in more than 140 countries. The sales of desktop PCs alone accounted for about 65% of Dell’s total revenues while the rest accounted for about 33%. In early 1988, the company has 16,000 employees. Dell’s Background and Vision Dell Computer was first known as PCs Limited in 1984, selling PC components and PCs under the brand name PCs Limited. Dell’s strategy was to sell directly to end users; by eliminating the retail markup, Dell was able to sell IBM clones at about 40% below an IBM PC price. By 1985, the company was assembling its own PC designs and had about 40 employees. Sales had reached $33 million by the year ending 1986. Michael Dell sought to refine the company’s business model, add needed production capacity, and build a bigger, deeper management staff and corporate infrastructure while at same time keeping costs low. It first international offices were opened in 1987 and was renamed Dell Computer. In 1998, Dell became a public company, raised $34.2 million in its first offering of common stock. Michael Dell’s vision was for Dell Computer to become one of the top three PC companies.

Engineer in Society

Engineers work to develop economic and safe solutions to practical problems, by applying mathematics, scientific knowledge and ingenuity while considering technical constraints. The term is derived from the Latin root â€Å"ingenium,† meaning â€Å"cleverness†. The industrial revolution and continuing technological developments of the last few centuries have changed the connotation of the term slightly, resulting in the perception of engineers as applied scientists. The work of engineers is the link between perceived needs of society and commercial applications. As for engineering definition it is a discipline, art and profession of acquiring and applying technical, scientific, and mathematical knowledge to design and implement materials, structures, machines, devices, systems, and processes that safely realize a desired objective or invention. The broad discipline of engineering encompasses a range of more specialized sub disciplines, each with a more specific emphasis on certain fields of application and particular areas of technology. The concept of engineering has existed since ancient times as humans devised fundamental inventions such as the pulley, lever, and wheel. Each of these inventions is consistent with the modern definition of engineering, exploiting basic mechanical principles to develop useful tools and objects. The term engineering itself has a much more recent etymology, deriving from the word engineer, which itself dates back to 1325, when an engine’er (literally, one who operates an engine) originally referred to â€Å"a constructor of military engines. † In this context, now obsolete, an â€Å"engine† referred to a military machine, i. e. , a mechanical contraption used in war (for example, a catapult). The word â€Å"engine† itself is of even older origin, ultimately deriving from the Latin ingenium (c. 250), and meaning â€Å"innate quality, especially mental power, hence a clever invention. † Later, as the design of civilian structures such as bridges and buildings matured as a technical discipline, the term civil engineering entered the lexicon as a way to distinguish between those specializin g in the construction of such non-military projects and those involved in the older discipline of military engineering (the original meaning of the word â€Å"engineering,† now largely obsolete, with notable exceptions that have survived to the present day such as military engineering corps, e. g. the U. S. Army Corps of Engineers. Engineering, much like other science, is a broad discipline which is often broken down into several sub-disciplines. With the rapid advancement of technology many new fields are gaining prominence and new branches are developing such as materials engineering, computer engineering, software engineering, nanotechnology, tribology, molecular engineering, mechatronics, etc. These new specialties sometimes combine with the traditional fields and form new branches such as mechanical engineering and mechatronics and electrical and computer engineering. A new or emerging area of application will commonly be defined temporarily as a permutation or subset of existing disciplines; there is often gray area as to when a given sub-field becomes large and/or prominent enough to warrant classification as a new â€Å"branch. † One key indicator of such emergence is when major universities start establishing departments and programs in the new field. For each of these fields there exists considerable overlap, especially in the areas of the application of sciences to their disciplines such as physics, chemistry and mathematics. Engineering is a subject that ranges from large collaborations to small individual projects. Almost all engineering projects are beholden to some sort of financing agency: a company, a set of investors, or a government. The few types of engineering that are minimally constrained by such issues are pro bono engineering and open design engineering. By its very nature engineering is bound up with society and human behaviour. Every product or construction used by modern society will have been influenced by engineering design. Engineering design is a very powerful tool to make changes to environment, society and economies, and its application brings with it a great responsibility. Many lists of engineering societies have established codes of practice and codes of ethics to guide members and inform the public at large. Engineering projects can be subject to controversy. Examples from different engineering disciplines include the development of nuclear weapons, the Three Gorges Dam, the design and use of Sport utility vehicles and the extraction of oil. In response, some western engineering companies have enacted serious corporate and social responsibility policies. Engineering is a key driver of human development. Sub-Saharan Africa in particular has a very small engineering capacity which results in many African nations being unable to develop crucial infrastructure without outside aid. The attainment of many of the Millennium Development Goals requires the achievement of sufficient engineering capacity to develop infrastructure and sustainable technological development. Safety is the state of being â€Å"safe† (from French sauf), the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or other types or consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable. This can take the form of being protected from the event or from exposure to something that causes health or economical losses. It can include protection of people or of possessions. Safety engineering is an applied science strongly related to systems engineering and the subset System Safety Engineering. Safety engineering assures that a life-critical system behaves as needed even when pieces fail. Continuous changes in technology, environmental regulation and public safety concerns make the analysis of complex safety-critical systems more and more demanding. Safety is often seen as one of a group of related disciplines: quality, reliability, availability, maintainability and safety. These issues tend to determine the value of any work, and deficits in any of these areas are considered to result in a cost, beyond the cost of addressing the area in the first place; good management is then expected to minimize total cost. Theoretically, safety-engineers take an early design of a system, analyze it to find what faults can occur, and then propose safety requirements in design specifications up front and changes to existing systems to make the system safer. But actually, safety engineers are assigned to prove that an existing, completed design is safe. If a safety engineer then discovers significant safety problems late in the design process, correcting them can be very expensive. This type of error has the potential to waste large sums of money. The exception to this conventional approach is the way some large government agencies approach safety engineering from a more proactive and proven process perspective, known as â€Å"system safety†. The system safety philosophy is to be applied to complex and critical systems, such as commercial airliners, complex weapon systems, spacecraft, rail and transportation systems, air traffic control system and other complex and safety-critical industrial systems. The proven system safety methods and techniques are to prevent, eliminate and control hazards and risks through designed influences by a collaboration of key engineering disciplines and product teams. Software safety is a fast growing ield since modern systems functionality are increasingly being put under control of software. The whole concept of system safety and software safety, as a subset of systems engineering, is to influence safety-critical systems designs by conducting several types of hazard analyses to identify risks and to specify design safety features and procedures to strategically mitigate risk to acceptable levels before the system is certified. Additionally, failure mitigation can go beyond design recommenda tions, particularly in the area of maintenance. There is an entire realm of safety and reliability engineering known as Reliability Centered Maintenance (RCM), which is a discipline that is a direct result of analyzing potential failures within a system and determining maintenance actions that can mitigate the risk of failure. This methodology is used extensively on aircraft and involves understanding the failure modes of the serviceable replaceable assemblies in addition to the means to detect or predict an impending failure. Every automobile owner is familiar with this concept when they take in their car to have the oil changed or brakes checked. Even filling up one's car with fuel is a simple example of a failure mode (failure due to fuel exhaustion), a means of detection (fuel gauge), and a maintenance action (filling the car's fuel tank). For large scale complex systems, hundreds if not thousands of maintenance actions can result from the failure analysis. These maintenance actions are based on conditions (e. g. , gauge reading or leaky valve), hard conditions (e. . , a component is known to fail after 100 hrs of operation with 95% certainty), or require inspection to determine the maintenance action (e. g. , metal fatigue). The RCM concept then analyzes each individual maintenance item for its risk contribution to safety, mission, operational readiness, or cost to repair if a failure does occur. Then the sum total of all the maintenance actions are bundled into maintenance intervals so that maintenan ce is not occurring around the clock, but rather, at regular intervals. This bundling process introduces further complexity, as it might stretch some maintenance cycles, thereby increasing risk, but reduce others, thereby potentially reducing risk, with the end result being a comprehensive maintenance schedule, purpose built to reduce operational risk and ensure acceptable levels of operational readiness and availability. The two most common fault modelling techniques are called failure mode and effects analysis and fault tree analysis. These techniques are just ways of inding problems and of making plans to cope with failures, as in probabilistic risk assessment. One of the earliest complete studies using this technique on a commercial nuclear plant was the WASH-1400 study, also known as the Reactor Safety Study or the Rasmussen Report. Once a failure mode is identified, it can usually be prevented entirely by adding extra equipment to the system. For example, nuclear reactors contain dangerous radiation, and nuclear reactions can cause so much heat tha t no substance might contain them. Therefore reactors have emergency core cooling systems to keep the temperature down, shielding to contain the radiation, and engineered barriers (usually several, nested, surmounted by a containment building) to prevent accidental leakage. Most biological organisms have a certain amount of redundancy: multiple organs, multiple limbs, etc. For any given failure, a fail-over or redundancy can almost always be designed and incorporated into a system. Health is the general condition of a person in all aspects. It is also a level of functional and/or metabolic efficiency of an organism, often implicitly human. At the time of the creation of the World Health Organization (WHO), in 1948, health was defined as being â€Å"a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity†. Only a handful of publications have focused specifically on the definition of health and its evolution in the first 6 decades. Some of them highlight its lack of operational value and the problem created by use of the word â€Å"complete. Others declare the definition, which has not been modified since 1948, â€Å"simply a bad one. † In 1986, the WHO, in the Ottawa Charter for Health Promotion, said that health is â€Å"a resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities. † Classification systems such as the WHO Family of International Classifications (WHO-FIC), which is composed of the International Classification of Functioning, Disability, and Health (ICF) and the International Classification of Diseases (ICD) also define health. Overall health is achieved through a combination of physical, mental, emotional, and social well-being, which, together is commonly referred to as the Health Triangle. Health and working together safety engineers plan, implement, and coordinate safety programs to prevent or correct unsafe environmental working conditions. They promote workplace and product safety by identifying and monitoring potential hazards to people or property. They then apply an advanced knowledge of industrial processes and human performance principles to reduce or eliminate the risk of injury or damage. To create a safe and environmentally sound workplace, engineers coordinate with outside organizations, such as fire departments or the Occupational Health and Safety Administration (OSHA); design and install safety devices on machinery or clothing; and investigate causes of industrial accidents to prevent further incidents. They also conduct tests to ascertain air quality, noise level, temperature, or radiation. Once the analysis is complete, they then consult with governmental organizations on how to handle such problems in compliance with safety regulations. Health and safety engineers then coordinate the training of workers on safety procedures using safety equipment, devices, and clothing. Working under the Health Department and the work involves is the planning, administration and performance of public health engineering duties concerned with the execution of one or more phases of the environmental health program. The work entails advising public officials or individuals on problems requiring professional public health engineering expertise, including measures for improvement and compliance with legal requirements, assisting in the promotion of public health through application of environmental health practices, assisting in the enforcement of the provisions of local and State health matters and investigations of related conditions and problems. The work is performed under general supervision of a Senior Public Health Engineer with leeway allowed for exercise of independent judgment in carrying out details of the work. Engineers also played a relatively indirect role in medicine until the last 40 to 50 years. They produced instruments and articles specified by doctors and medical practitioners. There was however an interesting contribution made by Isambard Kingdom Brunel in 1855. He responded to the scandal of the appalling conditions of the Crimean War military hospital, publicised by Florence Nightingale, by designing the first portable hospital of one thousand beds within six days of receiving a request for help from the War Office. The project was completed in five months from design to admission of the first wounded soldier. The introduction of anaesthetics in 1846 fundamentally changed surgery by suppressing pain. This gave surgeons more time and allowed for the developments of new techniques which made surgery more constructive. However modern medical developments really began in 1876 when Robert Koch, a German doctor, proved for the first time that microorganisms could cause disease. The first chemical agent to attack infection, salvarsan or ‘606’ (arsenobenzene) was developed by Paul Ehrlich in 1910 and although it had many side effects, remained the only means of curing acute infection until the second world war when penicillin was introduced. Although penicillin was originally discovered by Sir Alexander Fleming in 1928, it was the innovation and ingenuity of chemists and engineers such as Ernst Chain, who built for Beechams the fermenter which enabled bulk semi-synthetic penicillins to be produced. Whilst chemists and engineers were involved in delivering the benefits of microorganisms such as antibiotics and vaccines, electrical engineers were advancing and applying technology to the benefit of healthcare. Of special merit was Godfrey Hounsfield’s singular contribution in the 1960s of the development of three dimensional reconstructions from two dimensional (2D) X-rays, namely the brain scanner, later to be developed into the body scanner. Engineering in medicine has been an important and it’s believed that the role of the engineer in many areas of healthcare will grow. Constant innovation and development is needed to avoid the generations of the 21st century looking back at our surgical and medical techniques with the same appalled fascination in the 19th century. The ever-expanding array of medical technologies includes artificial hips and organs, endoscopy (enabling minimally invasive surgery), intelligent prosthetic devices (artificial limbs, hearing aids) and implantable devices (pacemaker, defibrillator), novel technologies used in cardiac catheterization, patient monitoring, and medical imaging. These developments have had a tremendous impact on the medical industry and have led to numerous technologies and medical devices without which modern medicine would be unthinkable. Today’s activities range from nano- to information technology and involve such diverse applications as microsensors, artificial organs, physiological modelling, genomics, molecular imaging, home care monitoring, ergonomics, information processing, data management, and patient safety. Environment in this case is natural environment, commonly referred to simply as the environment, encompasses all living and non-living things occurring naturally on Earth or some region thereof. The concept of the natural environment can be distinguished by two components. Complete ecological units that function as natural systems without massive human intervention, including all vegetation, animals, microorganisms, soil, rocks, atmosphere and natural phenomena that occur within their boundaries. Others is universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from human activity. The natural environment is contrasted with the built environment, which comprises the areas and components that are strongly influenced by humans. A geographical area is regarded as a natural environment (with an indefinite article), if the human impact on it is kept under a certain limited level. In engineering, is more related with environmental engineering whereas define as the application of science and engineering principles to improve the environment (air, water, and/or land resources), to provide healthy water, air, and land for human habitation and for other organisms, and to remediate polluted sites. Environmental engineering involves water and air pollution control, recycling, waste disposal, and public health issues as well as knowledge of environmental engineering law. It also includes studies on the environmental impact of proposed construction projects. Environmental engineers conduct hazardous-waste management studies to evaluate the significance of such hazards, advice on treatment and containment, and develop regulations to prevent mishaps. Environmental engineers also design municipal water supply and industrial wastewater treatment systems as well as address local and worldwide environmental issues such as the effects of acid rain, ozone depletion, water pollution and air pollution from automobile exhausts and industrial sources. At many universities, Environmental Engineering programs follow either the Department of Civil Engineering or The Department of Chemical Engineering at engineering faculties. Environmental â€Å"civil† engineers focus on hydrology, water resources management, bioremediation, and water treatment plant design. Environmental â€Å"chemical† engineers, on the other hand, focus on environmental chemistry, advanced air and water treatment technologies and separation processes. Additionally, engineers are more frequently obtaining specialized training in law (J. D. ) and are utilizing their technical expertise in the practices of Environmental engineering law. Most jurisdictions also impose licensing and registration requirements. Modern environmental engineering began in London in the mid-19th century when Joseph Bazalgette designed the first major sewerage system that reduced the incidence of waterborne diseases such as cholera. The introduction of drinking water treatment and sewage treatment in industrialized countries reduced waterborne diseases from leading causes of death to rarities. In many cases, as societies grew, actions that were intended to achieve benefits for those societies had longer-term impacts which reduced other environmental qualities. One example is the widespread application of DDT to control agricultural pests in the years following World War II. While the agricultural benefits were outstanding and crop yields increased dramatically, thus reducing world hunger substantially, and malaria was controlled better than it ever had been, numerous species were brought to the verge of extinction due to the impact of the DDT on their reproductive cycles. The story of DDT as vividly told in Rachel Carson's â€Å"Silent Spring† is considered to be the birth of the modern environmental movement and the development of the modern field of â€Å"environmental engineering. † Conservation movements and laws restricting public actions that would harm the environment have been developed by various societies for millennia. Notable examples are the laws decreeing the construction of sewers in London and Paris in the 19th century and the creation of the U. S. national park system in the early 20th century. Briefly speaking, the main task of environmental engineering is to protect public health by protecting (from further degradation), preserving (the present condition of), and enhancing the environment. Pollutants may be chemical, biological, thermal, radioactive, or even mechanical. Environmental engineering emphasizes several areas: process engineering, environmental chemistry, water and sewage treatment (sanitary engineering), waste reduction/management, and pollution prevention/cleanup. Contribution to society is engineers and scientists assess the impacts of a proposed project on environmental conditions. They apply scientific and engineering principles to evaluate if there are likely to be any adverse impacts to water quality, air quality, habitat quality, flora and fauna, agricultural capacity, traffic impacts, social impacts, ecological impacts, noise impacts, visual (landscape) impacts, etc. If impacts are expected, they then develop mitigation measures to limit or prevent such impacts. An example of a mitigation measure would be the creation of wetlands in a nearby location to mitigate the filling in of wetlands necessary for a road development if it is not possible to reroute the road. Engineers and scientists also work to secure water supplies for potable and agricultural use. They evaluate the water balance within a watershed and determine the available water supply, the water needed for various needs in that watershed, the seasonal cycles of water movement through the watershed and they develop systems to store, treat, and convey water for various uses. Water is treated to achieve water quality objectives for the end uses. In the case of potable water supply, water is treated to minimize risk of infectious disease transmittal, risk of non-infectious illness, and create a palatable water flavour. Water distribution systems are designed and built to provide adequate water pressure and flow rates to meet various end-user needs such as domestic use, fire suppression, and irrigation. Most urban and many rural areas no longer discharge human waste directly to the land through outhouse, septic, and/or honey bucket systems, but rather deposit such waste into water and convey it from households via sewer systems. Engineers and scientists develop collection and treatment systems to carry this waste material away from where people live and produce the waste and discharge it into the environment. In developed countries, substantial resources are applied to the treatment and detoxification of this waste before it is discharged into a river, lake, or ocean system. Developing nations are striving to obtain the resources to develop such systems so that they can improve water quality in their surface waters and reduce the risk of water-borne infectious disease. There are numerous wastewater treatment technologies. A wastewater treatment train can consist of a primary clarifier system to remove solid and floating materials, a secondary treatment system consisting of an aeration basin followed by flocculation and sedimentation or an activated sludge system and a secondary clarifier, a tertiary biological nitrogen removal system, and a final disinfection process. The aeration basin/activated sludge system removes organic material by growing bacteria (activated sludge). The secondary clarifier removes the activated sludge from the water. The tertiary system, although not always included due to costs, is becoming more prevalent to remove nitrogen and phosphorus and to disinfect the water before discharge to a surface water stream or ocean outfall. Engineers apply scientific and engineering principles to the design of manufacturing and combustion processes to reduce air pollutant emissions to acceptable levels. Scrubbers, electrostatic precipitators, catalytic converters, and various other processes are utilized to remove particulate matter, nitrogen oxides, sulphur oxides, volatile organic compounds (VOC), reactive organic gases (ROG) and other air pollutants from flue gases and other sources prior to allowing their emission to the atmosphere. Scientists also have developed air pollution dispersion models to evaluate the concentration of a pollutant at a receptor or the impact on overall air quality from vehicle exhausts and industrial flue gas stack emissions. To some extent, this field overlaps the desire to decrease carbon dioxide and other greenhouse gas emissions from combustion processes. Technology is an application of knowledge to the practical aims of human life or to changing and manipulating the human environment. Technology includes the use of materials, tools, techniques, and sources of power to make life easier or more pleasant and work more productive. Whereas science is concerned with how and why things happen, technology focuses on making things happen. Technology began to influence human endeavour as soon as people began using tools. It accelerated with the Industrial Revolution and the substitution of machines for animal and human labour. Accelerated technological development has also had costs, in terms of air and water pollution and other undesirable environmental effects. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The human species' use of technology began with the conversion of natural resources into simple tools. Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often (but not always) using results and techniques from science. The development of technology may draw upon many fields of knowledge, including scientific, engineering, mathematical, linguistic, and historical knowledge, to achieve some practical result. Technology is often a consequence of science and engineering — although technology as a human activity precedes the two fields. For example, science might study the flow of electrons in electrical conductors, by using already-existing tools and knowledge. This new-found knowledge may then be used by engineers to create new tools and machines, such as semiconductors, computers, and other forms of advanced technology. In this sense, scientists and engineers may both be considered technologists; the three fields are often considered as one for the purposes of research and reference. As for conclusion, engineer and engineering plays vital role in our life. Engineer has contribute a lot with the careful research and development using all the mathematical and science related in creating, solving and also improve our daily life. In existent of engineer also we are aware in the safety, health and environment. In ways, engineers identify what is safe and what not. Engineer create something in aided the medical profession thus improving the quality of life. Engineer also contributes in preventing pollution to occur and also find alternative for not destroying the environment. With more technological advancement, engineer have unlimited to what they can do in contribution to the society. Engineer must bear in mind, that everything must have it weakness and consequences. As such, engineer with obligation to serve the society must have good research and have think all the effect that could have happen before doing anything.
