The Boston Molasses Disaster Research Paper Example | Topics and Well Written Essays - 3000 words

The Boston Molasses Disaster - Research Paper Example (Dodero, n.d). The Boston Molasses Disaster was of particular interest in lieu of this paper because it talked of an almost fictional sounding disaster that had wrecked Boston and claimed the lives of its people due to the negligence of USIA and its technicians who overlooked critical engineering procedures which resulted in the infamous disaster. The method and procedure this paper adopted was to study secondary research and develop a paper based on that, with help from the images and information from the newspapers available online from that time. As a result of this, it was found that USIA was to blame for the Boston Molasses Disaster and in a lengthy and costly legal trial that followed suit, they had to pay heavy damages to the victims of the disaster in compensation. In summation, it was discovered how this disaster changed future engineering and industry practices as a result of learning from the mistakes that had caused it in the first place.

Ballistics Essay Example | Topics and Well Written Essays - 1250 words

Ballistics - Essay Example There are two types of ballistics, interior and exterior ballistics. Interior ballistics concerns itself with the thermodynamics and chemistry that occurs in a guns barrel. Exterior ballistics concerns itself with the motion of a bullet that comes from a gun. This paper concerns itself with the mathematics that occurs from the exterior ballistics. This paper seeks to identify how mathematics helps to determine the distance and trajectory of a bullet. Coupland and Rothchild (2011) denote that motion is of two types, that is natural motion, and violent motion. Natural motion faces resistance from air or water, basically because it occurs in such kind of a medium. An example of a natural motion is the falling of a stone, or the rising of a smoke. Violent motion on the other hand occurs as a result of an application of force. An example of a violent motion is the movement of a bullet from a firearm. Coupland and Rothchild (2011) denote that the weight of the object and the force in which an individual applies to a motion object will determine the distance and the speed in which the motion object under consideration will move. (Pender, 2012).Before determining on how to use mathematics to determine the distance and trajectory of a bullet, it is important to understand that a trajectory determination does not identify and reveal the occurrences prior to an individual holding the gun (McCoy, 2012). It only identifies the distance, and the nature of the weapons used by the criminals. In calculating the distance and trajectory of a bullet, it is important to denote that a bullet under motion faces two types of forces, that is the force of gravity, and the natural force brought by the air around which the bullet flies. In calculating a distance that a bullet covers, it is important to denote that bullets have a ballistic coefficient of G1 (Pender, 2012). The ballistic coefficient of a bullet (G1) allows an individual to scale the bullets drag to the standard projectile e stablished by the Gavre Commission. The standard ballistic coefficient of a bullet established by the Gavre commission was 1.000 (Warlow, 2012). This standard allows an individual to calculate how many feet’s a projectile will lose a given number of velocities in comparison to a distance a standard projectile will cover, after losing the same amount of velocity, under similar atmospheric environment. For example, a G 1 standard projectile drops approximately 2904 to 3000 fps over a distance of 100 yards. This is at a standard meteorological condition. If the bullet under consideration will have a ballistic coefficient of 0.5, the bullet will drop from 3000fps to 2904 fps in a distance of 50 yards (Kieser and Taylor, 2013). This distance is calculated in this manner,100 yards multiply by 0.5= 50 yards. From these calculations, we can denote that when the ballistic coefficient of a bullet is big, the weight and shape of the bullet have a lesser drag. The bullet will also lose i ts velocity in a slower manner, and the rate of its deflection by the wind is minimal. This calculation will mostly affect artilleries made in the standard shapes of the 1800s, in which the Gavre commission established the bullets ballistic coefficient (Warlow, 2012). However, in the current century, manufactures have different shapes of a projectile which also have a different G1standard.On this basis, different G I standards, and Ballistic coefficients work over a limited number of velocities. On this basis therefore, modern bullets have a specified ballistic coefficient, over a given and different velocity range. This is because the shapes

The I Am Sayings Of Jesus Religion Essay

The I Am Sayings Of Jesus Religion Essay There are seven statements in the book of John in which Jesus says, I am something. In this essay I will look at the list of the seven statements and I will begin with Jesus saying I am the light of the world. Throughout this essay, I plan to cover each of these sayings of Jesus separately and I will attempt to give a brief discussion on each of them. Each proclamation reveals the different facets of Jesus and gives a different sense of understanding, but, overall, all sum up the revelation of who Jesus is. Further I will look at why these statements are significant to our salvation. These statements are as follows: I am the good shepherd, I am the resurrection and the life, I am the true vine I am the way, the truth and the life I am the bread of life and, lastly, I am the door. I am Light of the world. John 8:12. John 8:12 proclaims the words of Jesus saying, I am the light of the world; he who follows me will not walk in darkness, but will have the light of life. There are many who follow false light that eventually leads to devastation; but the truth is found only in Christ. Eternal salvation should be our ultimate goal in life and Jesus is the only light that leads to a life of fulfillment. There was a strong opposition that came from the Pharisees against the claims of Jesus, they did not believe in His proclamation as the light of the world. They took him as one of those bubblers who did not know what He was saying. The word light here is used as a metaphor and it is repeatedly quoted throughout the Bible. The representation here is of Jesus being the truth. In other words if the Pharisees reject Him, then they are actually rejecting the truth, and because they reject the truth, then they walk in darkness. Therefore, they do not know who they are and were they are going as they are in darkness without Jesus. Just like the story of the adulteress woman, she lived in sin for many years and one day she was caught red handed in the very act. Then the Scribes and Pharisees came to Jesus and said to Him, Teacher, this woman was caught in adultery, and according to the Law of Moses, such deserve to be stoned to death. So the Scribes and Pharisees came to Jesus and said to Him, Teacher, this woman was caught in adultery, now Moses in the Law commanded us that such should be stoned, but what do you say? Jesus stooped down then later answered them saying if there is any among you without sin, let them be the first to throw a stone at her. Realizing their own wrongs, they began to leave one by one until they were all gone and the woman was left alone. Then Jesus said to the woman, has any one condemned you? she replied by saying, no one, Lord. And Jesus said to her, neither do I condemn you; go and sin no more. In this story we see that Jesus is the light of the world and indeed He is the truth. The accusers of the woman were convicted because the light was shown in their hearts and they saw their own sinfulness. Therefore the world is lost without Jesus. Darkness controls us and unless the light of Jesus shines upon us, we can see the truth. But while we have the light, we must believe in the light, that we may become children of the light (John 12:36). The light here signifies Jesus and that without Jesus in us and leading us, we walk in darkness and are lost. I am the good shepherd. John 10:11 Jesus said I am the Good Shepherd. Those who come before me are robbers and thieves and my sheep do not hear them. The shepherd who takes care of his flock and gives his life for the sheep is the good shepherd and not a hireling. The sheep hear his voice and he calls them by name and they follow him. And Jesus claimed Himself to be the good shepherd. The Jews actually thought He has a demon and is mad. This did not stop Jesus continuing His proclamation as the good shepherd. Sheep without a shepherd will be scattered and lost. For they know the voice of the and when he calls they hear him. The voice of a stranger, they do not hear. When its night time and the sheep are in, the shepherd guards the doorway. If a hireling tries to enter, the shepherd would defend his sheep by fighting back, to the extent of willing to lay down his own life for the sake of the sheep.  The fact that there is only one door to the sheepfold, the enemy cannot enter the sheepfold except through him. This is the sacrificial duty of every good shepherd, who is willing to lay down his life for the sake of the sheep. Jesus is our great shepherd; there will never be anyone like Him, willing to lay down His life for our protection. The shepherd had the right to lay down his life to purchase His flock. Jesus is the best of shepherds, none so skillful, so faithful, and so tender, as He. I am the resurrection and the life. John 11:25 I am the resurrection and the life; he who believes in me, though he die, yet shall he live, and whoever lives and believes in me shall never die (John 11:25-26). This is a proclamation that should settle our fear of death once and for all. Jesus declared Himself as the very essence of existence. In other words He is existence Himself and that apart from Him none can exist in this age and the age to come. Simply put, everything culminates in Him and everything holds together in Him. Jesus indicates that if He would let go of His hold on us, we would be nonexistent instantly. This deeply reveals our desperate need of Him because He holds us together. This is beautifully illustrated in the death of Lazarus. When Jesus was told about Lazarus death, He did not panic as we would definitely. He was inexplicably calm such that He went about doing what He was doing even after hearing such heart breaking news. For He said to the disciples, Lazarus is sleeping but I go to wake Him up, they said if he is sleeping, then he will get well. Jesus knowing that they did not understand, He emphatically told them that Lazarus is dead. He then said that this is for the glory of God and that the Son of Man may be glorified in this. Later when Jesus met Martha, Lazarus had been in the tomb for four days. Martha cried to Jesus after he finally came, that if had come early, and his brother would not have died. In contrast, Jesus said to her, your brother will live again. But Martha did not understand what Jesus was saying. Jesus said to them that if they would believe, then they would see the glory of God. In this story, Jesus demonstrated His resurrection power, showing that there was nothing He could not do. Jesus is the power of our salvation, He brings new life to the dead spiritually. By the mercies of God, how can the world ignore a person like this? I am the true vine. John 15: 1-6 Jesus declared that He is the true vine and His Father is the gardener. That He is the vine and we are the branches, therefore when we remain in Him and Him in us, then we bear much fruit. The branch that does not produce fruit, He takes away but the branch that bears fruit, He prunes so that it can produce more fruit. Like a tree and its branches, it is virtually impossible for the branches to be cut and expect them to live. The food of the branches flows through the trunk of the tree from the roots. Therefore if the branches are cut off, then there much needed nourishment is cut off as well and the branches wither and die. In the same respect, Jesus is our vine and we are His branches, we feed from Him, our lives are healthy because of Him. If we are cut off, like the branches of a tree, we wither and die. Jesus said that when we abide in the word and the word abides in us, anything is possible when we ask. Therefore we need the word of God in us and if the word dwells in us and we embrace it wholeheartedly, then and only then are we able to be productive to the glory of God. The scriptures say, man shall not live by bread alone but by every word that proceeds from the mouth of God. The scriptures also say that when the word of God is a lamp to our feet and a light to our path. The faith by which we received the word of Jesus purifies our hearts. The word refines us from the dross of the world and the flesh because it is a cleaning virtue. I am the way, the truth and the life. John 14:6. In this verse Jesus said that no one comes to the Father except through him, no one knows the Father except through him and no one lives the life of the Father except through him. In this passage of scripture, Jesus emphatically says that no one goes to the Father nor sees the Father except through me. One day Thomas said to Jesus, Lord, we do not know where you are going, and how can we know the way. And Jesus answered saying, You know me and you know my father also and from today you know Him and have seen Him. By this saying He meant if we see Him then we have seen the Father for the Father and the Son are one. What is truth? And what is a lie? Jesus called the devil a liar and the Father of lies. And that he speaks lies from his resources and that he is a liar from the beginning. Jesus is often quoted as saying, I tell you the truth He always told the truth because He is truth and He is true in every way. Grace and truth came with Jesus for it is said that, we have seen his glory, the glory of the Son of God, full of truth and grace (John 1:14) I am the Bread of Life. John 6:35 Jesus said, I am the Bread of life. He said that you go to buy bread that does not last, for after you eat it, you hunger again for more bread. Come and eat my bread and you will not hunger again and it is free. He also said to the Samaritan woman, come and drink my water and you will never thirst again. Not understanding what He meant, she said the well is deep, how can you give me water when you do not have something to draw water with. Jesus corrects her by saying, I am your well, and when you come and drink of me, you will never thirst again. The water from Jesus will become a fountain of water springing up into everlasting life. Like the Samaritan woman, Jesus was on several occasions misunderstood by people, for instance, He tells His followers that if they eat His meat, then they have eaten meat indeed and if they drink His blood, they have drunk drink indeed. His followers were so confused about what He meant such that they decided to walk away and thought amongst themselves that, He must be mad, how can we eat of His flesh and drink His blood? Most of the disciples turned and walked away from Jesus. However, how many times do we misunderstand Him today? We sometimes think we know, yet we do not. Jesus also fed the five thousand people that followed Him. He took a boys lunch, only five small loaves of bread and two small fish. He had the crowd sit down and He took the bread and fish; He gave thanks for the food, and then gave it out to the people. By a miracle hand of God, He multiplied the food such that there was more than enough for over 5000 people. During the night, Jesus walks on the water, gets into the boat and arrives at Capernaum. The next day, the people realize that Jesus is not there but do not understand how he left. They get into boats and travel to Capernaum and find Jesus there. They ask him, When did you come here? Jesus replies to them that the reason they are seeking him is because they want more food. The people asked how they can do that and Jesus tells them that they must believe in the one that God has sent. In other words, Jesus wanted them not only to follow Him for physical food that does not last but for food that is everlasting. And that is only accomplished by believing that Jesus Christ was sent from God and that He is the true bread of life and those who partake of Him will never hunger again. I am the door John 10:1-10 Jesus said, I am the door, if anyone enters by Me, he will be saved, and he will go in and out and find pasture. Jesus said this to emphasis a point about who He is. During the time of Jesus, animals were kept in sheep folds and these sheep folds had only one door for animals to go in and out. They would have a wall either built with stones or made from branches and they would be completely closed except for one entrance where the sheep went in and out. Usually the entrance would not have a gate across it but would simply be a gap. But at night when the sheep were in the pen, the shepherd himself would lie across the entrance. So this made shepherd himself to become the gate to the sheep fold. By lying across the entrance the shepherd could keep close watch on the sheep and protect them from any intruder or hireling that may threaten to attack the sheep. The Pharisees seem to prove his point when Jesus gives them this illustration and once again they just dont understand what He means. So Jesus makes it plain to them when He tells them in verse seven saying I am the door of the sheep. Jesus makes this even clearer in verse nine when He says If anyone enters by Me, he will be saved. So this is not as complicated as the Pharisees made it out to be. This is what John has been trying to let us know all the way through this gospel. The Jews had long understood that the Messiah would bring salvation. The coming of the Messiah was something they looked forward to. CONCLUSION The conclusion of the matter would therefore seem to say that, Jesus is throughout the gospel of John trying to reveal who He is. Though He is misquoted and misunderstood on several occasions, He still does not give up the sole task of trying to reveal why He is here on earth. The evidence of His arguments and statements prove this point. For He repeatedly says, I am the light of the world, I am the good shepherd, I am the bread of life and that I am the door. In all these I am sayings, Jesus is attempting to drive home the central idea that no one can be saved except through Him. He is not only our way to salvation but He is our salvation. Therefore to reject Him is as good as rejecting the very power of salvation.

The Cell Essay -- essays research papers

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa; others, such as nerve, liver, and muscle cells, are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function, all cells have a surrounding membrane and an internal, water-rich substance called the cytoplasm, the composition of which differs significantly from the external environment of the cell. Within the cell is genetic material, deoxyribonucleic acid (DNA), containing coded instructions for the behavior and reproduction of the cell and also the chemical machinery for the translation of these instructions into the manufacture of proteins. Viruses are not considered cells because they lack this transla tion machinery; they must parasitize cells in order to translate their own genetic code and reproduce themselves. Cells are of two distinctly different types, prokaryotes and eukaryotes; thus, the living world is divided into two broad categories. The DNA of prokaryotes is a single molecule in direct contact with the cell cytoplasm, whereas the DNA of eukaryotes is much greater in amount and diversity and is contained within a nucleus separated from the cell cytoplasm by a membranous nuclear envelope. Many eukaryotic cells are further divided into compartments by internal membranes in addition to the nuclear envelope, whereas prokaryotic cells never contain completely internal membranes. The prokaryotes include the mycoplasmas, bacteria, and blue-green algae. The eukaryotes comprise all plant and animal cells. In general, plant cells differ from animal cells in that they have a rigid cell wall exterior to the plasma membrane; a large vacuole, or fluid-filled pouch; and chloroplasts that convert light energy to chemical energy for the synthesis of glucose. Structure and Function Cells are composed primarily of oxygen, hydrogen, carbon, and nitrogen, the elements that make up the majority of organic compounds. The most important organic compounds in a cell are proteins, nucleic acids, lipids, and polysaccharides (carbohydrates). The "solid" structures of the cell are co... ...t of cells and cell products. Thus, a whole organism could be understood through the study of its cellular parts. In 1858 the German pathologist Rudolf Virchow's theory, that all cells come from preexisting cells, led to the development of ideas about cell division and cell differentiation. The development in the late 19th century of techniques for staining cell parts enabled scientists to detect tiny cell structures that were not actually seen in detail until the advent of the electron microscope in the 1940s. The development of various advanced optical techniques in the 20th century also increased the detection power of the light microscope for observations of living cells. The study of cells is not limited to describing structures. A central concept in modern cytology is that each structure has a function that may be understood as a series of biochemical reactions. The understanding of these functions has been greatly aided by the development of cell fractionation techniques, using an ultracentrifuge to separate specific intracellular structures from the rest of the cell. Another technique is tissue culture, by which specific kinds of cells can be isolated and grown for study.

Cells range in size from the smallest bacteria-like mycoplasmas, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function, all cells have a surrounding membrane and an internal, water-rich substance called the cytoplasm, the composition of which differs significantly from the external environment of the cell. Within the cell is genetic material, deoxyribonucleic acid (DNA), containing coded instructions for the behavior and reproduction of the cell and also the chemical machinery for the translation of these instructions into the manufacture of proteins. Viruses are not considered cells because they lack this transla tion machinery; they must parasitize cells in order to translate their own genetic code and reproduce themselves. Cells are of two distinctly different types, prokaryotes and eukaryotes; thus, the living world is divided into two broad categories. The DNA of prokaryotes is a single molecule in direct contact with the cell cytoplasm, whereas the DNA of eukaryotes is much greater in amount and diversity and is contained within a nucleus separated from the cell cytoplasm by a membranous nuclear envelope. Many eukaryotic cells are further divided into compartments by internal membranes in addition to the nuclear envelope, whereas prokaryotic cells never contain completely internal membranes. The prokaryotes include the mycoplasmas, bacteria, and blue-green algae. The eukaryotes comprise all plant and animal cells. In general, plant cells differ from animal cells in that they have a rigid cell wall exterior to the plasma membrane; a large vacuole, or fluid-filled pouch; and chloroplasts that convert light energy to chemical energy for the synthesis of glucose. Structure and Function Cells are composed primarily of oxygen, hydrogen, carbon, and nitrogen, the elements that make up the majority of organic compounds. The most important organic compounds in a cell are proteins, nucleic acids, lipids, and polysaccharides (carbohydrates). The "solid" structures of the cell are co... ...t of cells and cell products. Thus, a whole organism could be understood through the study of its cellular parts. In 1858 the German pathologist Rudolf Virchow's theory, that all cells come from preexisting cells, led to the development of ideas about cell division and cell differentiation. The development in the late 19th century of techniques for staining cell parts enabled scientists to detect tiny cell structures that were not actually seen in detail until the advent of the electron microscope in the 1940s. The development of various advanced optical techniques in the 20th century also increased the detection power of the light microscope for observations of living cells. The study of cells is not limited to describing structures. A central concept in modern cytology is that each structure has a function that may be understood as a series of biochemical reactions. The understanding of these functions has been greatly aided by the development of cell fractionation techniques, using an ultracentrifuge to separate specific intracellular structures from the rest of the cell. Another technique is tissue culture, by which specific kinds of cells can be isolated and grown for study.

Beat Me Skeet Me: A Critical Analysis of “Secretary” Essay

â€Å"Secretary,† the movie, is a provocative and warped love story. Viewers may go purple with rage or gray with disgust, while many may turn pink with embarrassment in order to hide the red of arousal. This movie crosses dangerous psychological territory: the threshold between desire and pain, between surrender and subjugation. Gaitskill’s â€Å"Secretary† is more about submissiveness and â€Å"sexual perversion† (Garrett 1). Critic Regina Weinreich argues that Gaitskill’s debut is startling and refreshing due to the neediness she portrays in her characters; their â€Å"vulnerablility makes them . . . victims of their own behavior† (Weinreich 1). Steven Shainberg’s film, working from a short story by Mary Gaitskill, is about two specific characters. Some will claim that Shainberg’s film makes sexual abuse palatable, maintains that women secretly crave submission to a dominant male, and makes the case that humiliation at the hands of a man can lead to psychological freedom, not to mention all the awful things it implies about the position of secretaries. Yet, â€Å"Secretary† is so consistent in its characters that it’s fair to say that only in the case of these two weirdly satisfying people are any of the instances true to life. The film shows how specific characters bridge their isolation (Shainberg 3). The additions to the film adaptation of Mary Gaitskill’s â€Å"Secretary† makes the story more fascinating and better justifies the characters’ actions. See more: how to write a good critical analysis essay Mary Gaitskill’s â€Å"Secretary† is about a frumpy wallflower who’s so â€Å"bruised emotionally† that she’s struggling to â€Å"connect with [her]self† (Weinreich 1). She gets a job as a secretary and ends up in a strange sadomasochistic relationship with her employer. It’s a great premise for a story, especially in its absurd moments, as when the lawyer begins to spank his new hire for every typo she commits. Gaitskill is an insightful writer; her stories are â€Å"lean and quick and tightly controlled,† yet the end of â€Å"Secretary† is flat, and too serious (Garrett 1). Gaitskill’s humor in â€Å"Secretary† is dry and teasingly salacious; it’s a more subtle incitement of sadomasochism. Having been spanked and sexually humiliated by her employer, the narrator feels estranged from her own body. And she likes that estrangement; it fires her sexual fantasies. When you finish reading the story, you think to yourself, â€Å"So what? Why should I care for this character?† The secretary begins and remains much the same. She is the kind of person who suffers from such low  self-esteem that she invites and accepts abuse. She â€Å"frequently wonder[s] if there’s something wrong with [herself]† (Hallgren 2). You can’t blame the lawyer for maltreating her and you find yourself wishing that he’d managed to knock some sense into her. It’s hard to feel for anyone so stubborn and resigned. The protagonist in the story wasn’t known to enjoy pain before the incident, so it’s hard to justify how she responds to her boss’s abuse. The only explanations for her reaction are that she was bewildered, curious, or simply passive and submissive (Kakutani 1). In the movie, Lee Holloway is a lost young woman with family issues. She’s just been discharged from the asylum and has gone right back to what put her there in the first place, a compulsion to cut herself. Lee finds a job as a legal secretary at the office of attorney Edward Grey. When she first enters the office on a rainy morning, she’s wearing a hooded rain coat, which makes her look innocent and introverted compared to Grey in his business suit. The description of the lawyer in the story gave no real feeling of dominance, except that he had an aggressive hand shake. The movie, on the other hand, gives the audience a very clear image of his strength and control, and all his little quirks, such as the red markers he keeps and his built up energy that he exhausts by working out. In the film, the characters’ motives and personalities are â€Å"not only dramatically palatable but emotionally plausible† (McCarthy 1). Once we get to know Grey, we learn that he’s trying to let out his inner pervert, and the effort is making him into a repressed wretch; his eyes bulge with suppressed rage and fear. Lee is the fly the spider cannot resist. Through their increasingly bizarre relationship, Lee follows her deepest longings to the heights of masochism and finally to a place of self-affirmation. The boss-secretary relationship starts to take on master-slave overtones before the big moment when, as punishment for a couple of innocent typos, Grey demands that Lee bend over his desk so he can administer a few thwacks across her ass. Lee is transformed. As Lee submits to this humiliation, she experiences an â€Å"exhilarating release and a shock of recognition† (Ansen 1). The episode allows her to stop the impulse of cutting herself. Louise Pembroke, a self-mutilator herself, argues that â€Å"S&M  is not a self-harm substitute. Pain as pleasure is not the same as pain from self-injury† as the film suggests (Pembroke 3). Joe Queenan believes that â€Å"Lee has [just] found a less destructive and more socially acceptable outlet for her . . . masochistic tendencies† (Queenan 1). As she and Grey continue their dominance/submission games, she begins to dress better, carry herself with confidence and lose the social awkwardness that was her personality. In Gaitskill’s story the spanking incident was â€Å"just another quality in the cumulative discovery of character† (Johnson 1). Debby came to little if any revelation in the story. The characterization of Lee makes â€Å"Secretary† a charming comedy. As she puts up with the conventional courtship practices of her gentle but dull boyfriend, who is not in Gaitskill’s story, she’s as ungainly and self-conscious as a stranger. Peter asks Lee â€Å"‘I didn’t hurt you did I?’ after a bout of imagination-free sex. Lee stares into space, her gaze signaling, ‘If only'† (Kemp 2). The spanking incident leads to a flowering of Lee’s sexual self that pushes aside the boyfriend, her twittery mother, her snotty sister and her drunk father. Grey’s imperious manner and his imposing office are the triggers that allow Lee to escape her cocoon and become a kinky sadomasochist butterfly. The twist here is that Grey is hounded by shame and it’s up to Lee to rescue him from his self-loathing. This helps show the film’s point that sexual liberation lies with surrender to one’s own kinks, and that even perverts deserve to find a soul mate. Lee was â€Å"so profoundly moved by someone having discovered her secret source of satisfaction† that she was able to be open about it (McCarthy 2). â€Å"Secretary† is, at its core, a little love story which dares to suggest that genuine love can come from sexual dominance. In the written story, the lawyer doesn’t show any remorse, except to send Debby a severance check. And, Debby barely comes to any epiphany over the strange occurrence with her boss. In the film, however, the secretary begins as a self-conscious cutter and transforms into a free and beautiful woman. This is what distinguishes the film as truly perverse; it envisions S&M not as a stereotypical session with whips and chains, but rather as a force capable of transforming a person.  Before the sadomasochistic relationship developed, Lee mutilated herself privately. When their relationship began to unfold, â€Å"it [was] as if [Lee admitted] somebody else into [her] private world† of masochism (Shainberg 1). The protagonist of Gaitskill’s story seems to accept the sadistic behavior of her boss as a reinforcement of her own piteousness, whereas the protagonist of the movie attains a kind of self-liberation through it. When Lee submits to the lawyer’s demand that she sit at his desk until he returns in order to prove her love, she undergoes an endurance test. She waits there with her hands flat on his desk as day turns into night and back again to day, eating and drinking nothing, urinating on her fiance’s mother’s wedding dress, and enduring confrontations with her fiance, family members, a priest and tv crews. The effect of this incredible act of submission, which is found in the film but not the story, is not to reinforce the secretary’s low self-esteem, but to demonstrate that she finds within herself a power to endure. She approaches the act not as though it were a psychodrama but as though it was a contest of self-restraint. Her ability to suffer surpasses the lawyer’s ability to enjoy the spectacle of suffering, her masochism exceeds his sadism, and with this realization they enter into a strange new territory: a loving relationship in which the usual imbalance of power between sadist and masochist is offset by the strength of her masochism. The two characters seem destined for each other. Mary Gaitskill’s short story is well written, but touches more on abuse and submissiveness than sadomasochism and love. Gaitskill shows the characters relationship as being determined â€Å"by the convergence of mutually compatible fantasies,† rather than â€Å"such abstract passions as love, hate or desire,† which are portrayed in the film (Kakutani 1). The movie is much more intriguing and effective at getting a point across. Short stories, unlike films, are limited in the amount of information that can be portrayed, and the depth of which characters can be depicted. The protagonist’s self inflicted pain, her horrible family ties, and her boyfriend are just a few of the additions to Gaitskill’s story that make the plot and characters in the movie stronger.

Macroeconomic Analysis of Germany Essays

Macroeconomic Analysis of Germany Essays Macroeconomic Analysis of Germany Essay Macroeconomic Analysis of Germany Essay Its goal was to boost the relatively low economy by stimulating people to spend and consume. However, due to a general Insecurity in the population and the peoples lack of confidence, consumption failed to amplify, as hoped, despite the Increase in disposable income. In addition, despite the Reform, after its implementation, investment also slightly decreased. The lowering of the interest rates by 275 basis points in 2001 increased the money supply and led to a higher consumption, which positively reflected on the GAP growth. However, the lower Interest rates were not able to accelerate Investment and employment. Nevertheless, the Euro appreciated against the US Dollar, which In turn ad a positive influence, as exports and imports maintained their growth. After continuous depreciation of the Euro against the Dollar, up until its all-time low at the end of October 2000, the CB, along with the US and Japanese monetary authorities, intervened and increased the interest rates twice, both by 0,25%. By doing so they could first avoid a threat of an Increase of domestic prices due to inflation and also augment Imports due to the appreciation of the Euro. Furthermore, the skyrocketed foreign direct Investment In 2000 was reduced by 182. 52 billion Euros In 2001 The opening of a single market in 1 993 had an overall positive influence on the German economy, especially in the trade sector, where exports increased by 10,6% until 2002, totaling 660,6 billion Euros.

THE WAVE BEHAVIOR OF MATTER Louis de Broglie (1892-1987) â€Å"Depending on the experimental circumstances, radiation appears to have either a wavelike or a particle-like (photon) character. † o**As the electron moves about the nucleus, it is associated with a particular wavelength. The characteristic wavelength of the electron, or of any particle, depends on its mass, m, and moving at speed, v. oThe quantity mv for any object is its momentum. oMatter waves, wave characteristic of material particles. oThis hypothesis is found to be applicable to all matter; any object of mass and velocity would give rise to a characteristic matter wave. Uncertainty Principle -There is an inherent uncertainty in the precision with which we can simultaneously specify the position and momentum of a particle. This uncertainty is significant only for particles of extremely small mass, such as electrons. oWerner Heisenberg (1901-1976) ?â€Å"The dual nature of matter places a fundamental limitation on how precisely we can know both the location and the momentum of any object. The limitation becomes important only when we deal with matter at the subatomic level (that is with masses as small as that of an electron). † E. QUANTUM MECHANICS AND ATOMIC ORBITALS Erwin Schr? dinger (1887-1961) oQuantum physics opened a new treatment of atoms, electrons, ions and molecules: by describing it mathematically oUsed Broglie’s hypothesis that electrons can be described as a wave. oSolutions to the equation are called wave functions (energy state of an atom). ?WAVE FUNCTIONS: ?Only certain wave functions are allowed. An electron can only have certain energy states: the energy of the electron is quantized. ?They are called orbitals. ?Its square (? ) is called either probability density or the electron density. Mathematical description of a region in space where an electron has some probability of being found. ?Each wave function (or each energy state/orbital) is characterized by a set of 3 quantum numbers: n, l, ml oSchr? dinger’s theory chose to define the energy of the electron precisely. Therefore, according to the uncertainty principle, this would result in a large uncertainty finding the locatio n of the electron. oWhen the Schr? dinger’s equation for the H-atom is solved, the resulting wave functions contain 3 integral numbers called quantum numbers. Orbitals and Quantum Numbers oWhat for? ?Solutions to wave equations given ?Energy of electron ?Probable location of electron ?Identify an orbital oTo identify an orbital, we use THREE quantum numbers. oTo describe an electron, we use FOUR quantum numbers.

Club it part II - Essay Example ‘CLUB IT’ Business Issues As more and more customers are visiting the club, there is no mechanism to emphasize individual customer perspective, resulting in vague customer management. For instance, customer interest and likenesses related to the club activities. In this way, the organization cannot take appropriate decisions based on the interest and likenesses of the customers of the club. Likewise, there is no data of ‘customer interaction’ with the ‘Club IT’ services; the staff cannot entertain the customer in a better way. Moreover, there is no interaction of customers with the ‘Club IT’ system. The club currently does not support analytical monitoring of the stock items. It means that the supplier do not know the product demand in the club. The club does not guarantee to provide the merchandize the customer wants. This may impact in a negative customer loyalty issue. The club’s mission is to earn the loyalty of the custo mer. There is no criterion for setting strategic goals for better management, customer relations and satisfaction. The organizations must evaluate the strategic planning activities for the betterment and growth. The planning relies on the available assets of the organization. This area also needs improvement as planning is essential before implementing any strategy. For understanding key issues having a significant impact on the survival and success of the organizations strategic planning is an essential process (Efendioglu & Karabulut, 2010). Implementing E-commerce Systems For making the 3 p relating to (peoples, employees and culture) Customer relationship management system is required. The basic factors which enabled the implementation of customer relationship management systems are the expansion of computers and the global telecommunication infrastructure (Lost'akova, 2009). Customer Relationship Management Customer relationships are occurring on several levels in the club. CRM will share the customer relationship data within the organization employees for making better decisions, follow ups on all dissimilar levels in dealing with the customer. The CRM system will make a customer a useful entity for the organization. The customers are authorized to find information and services to acquire a conclusion resulting in fewer customer staff and order entry. The customer relationship data is centralized and is accessible to all the Club’s employees. It means that all the customer data and history are just away from the ‘click of the mouse’. The customers will feels as a part of the ‘Club IT’ team because they will get what they want, as only delighted customers provides a superb level of loyalty. If the customer satisfaction amplifies, Club IT will get more business and revenue. Supply Chain Management System Supply chain management systems are implemented globally for utilizing their supply chain activities in a productive approach for competitive advantages (Kanji & Wong, 1999). By implementing supply chain management systems, the ‘Club IT’ will able to reduce costs and maximize productivity for inventory and stock management

Cap-and-Trade Assignment Example | Topics and Well Written Essays - 250 words

Cap-and-Trade - Assignment Example This approach is based on credits which are issued to corporations by governments or a set authority. A corporation is issued with a set limit of the pollution level that they can cause in a given region. If it can achieve that, they can transfer their credits to another company for a given fee (Burney, 2010). Therefore, cap and trade approach creates a marketing system for those companies that are better or are able to reduce their emissions and at the same time is punishes those companies that can not be able to do so financially. On the other hand, carbon tax is a tax imposed on carbon fuels. This approach offers corporations and governments a cost effective way of reducing greenhouse emissions in to the atmosphere. Carbon tax approach is mostly applied in OECD countries based on energy products and motor vehicles (Burney, 2010). There has been increased opposition to this approach citing concerns that it can lead to firms relocating and people losing jobs. On cap and trade approach, there are no emissions costs but the influence is on the broader economy. Therefore, this approach favors the corporations. That means that whenever anyone at a personal level does any mistake he or she will not be involved. On the other hand carbon emissions are always monitored by the carbon in the fuel (Burney, 2010). I also find that very far fetched because homesteads emit as much greenhouse gases as corporations. Therefore, in my opinion I believe these measures are not enough to combat climate
