Understanding Of Market-Based Management Term Paper

Understanding Of Market-Based Management - Term Paper Example b). The Vantage Point of Dispersed Knowledge Dispersed knowledge possessed by the isolated individuals is better than centrally planned expert knowledge in coordinating human economic activities. It is argued that â€Å"historical experience shows that market economies, which rely on the dispersed knowledge and independent judgment of numerous consumers and producers, consistently provide a dramatically higher quality of life than centrally planned economies" (Gabble and Ellig, 1993, p. 5). It is important to note that the logic of market functioning is not only applicable to inter-businesses relations but also to the governing of specific business organizations. Simply speaking, the idea of dispersed knowledge possessed by the customers at the vantage positions of the market is equally applied to the ‘within' of the corporations too. III. Koch Industries and Market-Based Management At Koch Industries, the application of market-based management saw a 2000 fold increase in the book value after the policy was initiated in the early 1990s. For them, it is a "philosophy that enables organizations to succeed long term by applying the principles that allow free societies to prosper" (Koch, 2007, p. vii). Importantly, at Koch industries, "vision, virtue and talents, knowledge processes, decision rights and incentives" are the five dimensions of market-based management (Koch, 2007, p. vii). All these five dimensions were applied in a holistic manner at the Koch Industries so that the effect was always transformative.

Sherlock Holmes stories Essay Example for Free

Sherlock Holmes stories Essay The Sherlock Holmes stories were first published in strand magazines in the year 1891. The author Conan Doyle, was inspired by other writers including R. L Stevenson, who wrote adventure stories, and Edgar Allen Poe who wrote horror and crime stories. He was also influenced by real events, such as the Jack the Ripper case which was happening at the time. Many people at that time thought it was nosy and disrespectful to read real life stories about dead people, so these fictional stories made them feel less guilty. The fictional stories also calm the public because many real life cases werent solved but the Sherlock Holmes cases always were. This gave people hope and made them less scared. Conan Doyle engages his readers by portraying life in Victorian England in an engaging way. In the man with the twisted lip the reader is introduced to opium dens. Opium was a legal drug at the time of the Victorians. They used to go the little dens underground which women were deprived of using: There were bodies lying in strange fantastic poses, with bowed shoulders and bent knees. Dr Watson said Isa Whitney made good of an opium den in the farthest part of the east of the city. This showed that Watson morally disapproves of these drugs. The fact that they smoked in the east is that they dont want to smoke I an respectable area so the have opiums farthest part of the east of the city. Colonialism was portrayed in The Speckled Band as Dr Roylott set up a medical practice in India. Another thing about Victorian times was the difference in authority and rights, and how the white upper class could easily get away with murder. An example of that was colonialism; in the story Dr Roylett killed his native butler who was Indian. However Dr Roylett was English and people like him were seen as powerful. So when he killed his butler he could easily get away with the capital punishment. However if he was an Indian he would have got a death sentence. This is because in the Indian culture who ever murders shall be repaid by being sentenced to death. Britain was as patriarchal society where the men were dominant and the bread-winners, and governed their own families by paternal right. An example is of Dr Roylott, his wife died, and she had left a lot of money. However the money had to go to his daughters when they marry. That is when the complications happen as Dr Roylott did not want to give the money away. Arthur Conan Doyle indulges and engages his readers into his books, Doyles talent was seen as he was describing his characters in an interesting way, e. g. The Man with the Twisted Lip. Holmes was disguised as an old man and he was very thin. Also much wrinkled bent with age, and an opium pipe dangling between his knees. He went to the opium bar where people drink and smoke cocaine, he thinks that the dens are dark gloomy and socially unpleasant place to be. This is shown of the sentence; approached by a steep flight of steps leading down to a black gap like the mouth of a cave. Also I found the latch and made my way into a long, low room, thick and heavy of an emigrant ship. This is strange for the readers as they do not expect a detective that solves mysteries and problems to admit that he also smoke cocaine. Further the author gave Holmes a personality that surprises readers. He says I suppose that you imagine that I have been addicted opium smoking and to cocaine injections. This shows that he has a dual personality. He is two sided, smoking cocaine then solving a mystery which is eccentric. Conan Doyle uses contrast in The Red Headed league to represent Holmes, it states and extreme languor to devouring energy. This suggests that one minute Sherlock was tired and lazy, the next he was bursting with energy. Conan Doyle is also good at using sexual imagery. Where it states lust of the chase, that would suddenly come upon him, this shows that he is passionate about his job and loves it the way a man loves a woman. He also uses effective animal imagery, Hunt down describes him as a vicious as a predator hunting down its prey. Conan Doyle describes settings in an interesting way. In The Red Headed League he uses exaggeration when he says every man who has a shade of red in their hair into the city answered the advertisement. He also uses good personification e. g. fleet street was choked. This is good because the reader knows that Fleet Street is not human because only humans choke when there is too much food consumed so suffocating. However fleet Street choked means it was crowded up with people and hardly any space. This is a good way too keeps the readers engaged and thinking. Color imagery to gives a better image of the scene e. g. Irish setter, brick, liver, clay. So it is not just saying red or blue bricks however adding metaphors. So it is making the reader imagine the colors it their head on what it looks like. Conan Doyle also uses a range of similes e. g. court looked like a casters orange barrow it gives the reader a picture on how many red headed people, its crowded this showed how the court may have looked like. Furthermore he describes the settings of his stories in a way that interest the readers. In the speckled band, as Conan Doyle uses pathetic fallacy. Pathetic fallacy is when nature reflects the mood, like; the wind was howling, rain was beating splashing against the window. This is a bit like personification which gives an impression that the weather is horrible, reflecting the awful tragedy that is occurring in the house. The weather represented the mood and atmosphere of the scene in the story. The house was described as, the building was of grey, lichen-blotched stone, with a high central potion and two curving wings, like the claws of a crab, thrown out on each side, in one of these the windows were broken and blocked with wooden boards, while the roof was partially caved in, a picture of ruin. The poor state of the house represents the deterioration and poor mental health of Dr Roylett. The stories are all structured in a similar way. In Sherlock Holmes stories is usually detective work it usually follows as. A client introduces the case to the detectives. In The Speckled Band there are two victims, one already dead, the other, Miss Helen Stoner, fearing for her life. When we first see Miss Helen Stoner in the story, she is dressed in black and heavily veiled. We can tell that she is terrified straight away when she talks. The first thing she says is It is not cold which makes me shiver, said the woman in a low voice. It is fear, Mr. Holmes. It is terror. The impact on the reader for this shows exactly how she was feeling, and how scared she was because she believes that she is going to die like her sister that died two years before. She believes that her sister was either frightened to death or killed by gypsies, because when this woman Helen found her sister the last words that she said were: Helen! Oh my God, Helen! It was the band! The speckled band! Next the detective analyses the client to demonstrate their detective skill. This was shown when he observed a train ticket in Mrs. Helen right glove. He also worked out that she took a cart before reaching the station because her jacket was muddy. He worked that one out because he said there is no vehicle save a dog cart which throws mud in that way, and then only when you sit on the left hand side of the driver. This gave Helen stoner a shock as to the series of accurate information. This shows that Sherlock was a bit of a show off demonstrating his extraordinary skills. Being as clever as that is essential for a successful detective. After that the detective visits the crime scene. At night Sherlock went to Dr Roylottes house. He gave the woman set instruction to lock herself in her room so the detectives would sleep in her sisters room for the night. So Sherlock wanted to investigate why there is a constant whistle during the night. Holmes investigated the whole house and he build up a plan to catch the murderer. Holmes had found out that there was an air-vent that was inside the house between the sisters room and the stepfathers. Holmes now was in the room that Helen was supposed to be in and suddenly the light was lit in the stepfathers room, and then Sherlock jumped and hit the bell robe under the air-vent which revealed a snake.

education :: essays research papers

Educating our Youth The Authors that we read in class all had esteemed criticism when talking about our nations education system but the one essay that stood out the most for me was about our children being more interactive with the community. Robert Coles argues that our childred need to be more respectable towards elders and be more involved in the growth of the community.   Ã‚  Ã‚  Ã‚  Ã‚  Respectively I think that Mr. Coles makes a very convincing argument, and that when you break down all of the other arguments, everything pieces together under one major category. Bell Hooks argues that our schools are too large and that the students need to feel a sense of surrounding in order for them to be able to learn better, Ms. Meier has a convincing argument that standardization of our school just like the ones in Europe are needed, and Linda Darling-Hammond argues that there is unequal opportunity among our schools specifically dealing with racism distributed throughout our school system.   Ã‚  Ã‚  Ã‚  Ã‚  When you look at Bell Hook’s argument that our schools are too large and that the students that are going to school in the city are not getting the same education as the students in the suberb’s. This argument can directly tie into the fact that yes there defiantly needs to be a more teacher to student ratio, because in every statistical analysis of the school system the less students in a class, the more comfortable the student is in his surrounding and the easier it is for the student to learn. Basically this situation can be solved by involving the student in the school, and in the community better. Solving a situation like cutting classroom size down with flooding more money into schools isn’t going to solve the way that students learn. I believe that students learn by the influence of others around them, others like their parents, their role models, and fellow classmates.   Ã‚  Ã‚  Ã‚  Ã‚  I don’t fully agree with the fact that there is unequal opportunity among students of different race, or that there need to be a standardization among grades for students like there is in Europe. The problem here in America is that kids aren’t feeling the connection with their peers. Kids don’t have motivation to learn, they see that their parents are not tied to their lives and they don’t feel that connection with the community like they are supposed to.

Equus Essay

Peter Shaffer’s play, Equus, tells a young man’s story of faith and struggle. Through Alan, Shaffer explores man’s relationship with God and himself, the concept of pain and passion, and eventually, shame. Indeed, Alan blinded the horses because he was shamed, not merely of his inability to perform, but more so because Equus, through the horses’ eyes, witnessed how he gave in to temptation and betrayed his god. Alan is like any man who is brought up to his parents’ beliefs. In his case, his mother was a devout Christian who read to him verses from the Bible, where he learned of God and Jesus. His father, on the other hand, was an atheist, and seeing Alan’s growing interest in religion tore the picture of the crucifix Alan had and replaced it with a picture of a horse. This is a powerful act of symbolism. The young Alan was confused because of his parents’ differing religious beliefs. He could sense that his father did not approve of the kind of fervent religion his mother is practicing, and but Alan has already been raised to love God. He could have just become a nominal Christian; instead he turned his intense beliefs towards a substitute god, a god that his father does not hate. Hence, Equus is born – his conception of a deity embodied in every horse. Yet, essentially, his faith remains traditional orthodox Christian. Like God, Equus sees everything, like Jesus, Equus suffers for the sins of the world. Alan’s devout love in Equus culminates to his riding the horse Nugget naked and barebacked, flagellating, riding to the point of sexual/mystical/religious climax, when he screams of his love and his desire to be one with the horse. This image illustrates Alan’s intense religious beliefs that he wants to share the pain, the passion or the suffering of Equus, and be one with him, akin to the intense devotion of saints. In the next part of the play, Alan goes with Jill to a pornography theater where they accidentally run into his father. This leaves an impression to Alan that sexual desire is common to all men. It can be said that since he found his father there, he made the logical conclusion that it was something that his father does not disapprove of. So when Jill suggests they have sex in the stables, he acquiesces. But the presence of the horses makes him nervous, and he is unable to get an erection. He becomes frustrated, and he threatens away Jill. He is more than just ashamed because he was not able to perform. He was ashamed because he could feel Equus’ eyes on him, and he knows that he has sinned. Alan felt guilty about his act, about his giving in to temptation, his attempt to do it with Jill, because he perceived it as an act of betrayal to his god. He declared his devotion and desire to be one with Equus, and yet he found himself a sinner, one of those who cause Equus’s/Jesus’s pain and suffering that he professed to want to share intensely. Whereas before he devoted himself body and soul to Equus, now he has succumbed to his body’s desire and suddenly he is aware of his nakedness. His nakedness is metaphorical with his nakedness on stage and the nakedness of Adam and Eve in Genesis. Literally he becomes aware of his nakedness, when previously he rode the horse naked anyway. This awareness brings forth shame, and since his depiction of god is within reach in the form of the horses, he lashed out at them. Consumed by shame, he vents out his anger and puts out the horses’ eyes, so that he they, and Equus, through them, could no longer see him naked, nor would they be able to see his sins.

Succubus Shadows Chapter 15

It was 1942, and I was in France. I didn't want to be in France. I hadn't wanted to be there for the last fifty years, yet somehow, Bastien kept talking me into staying. There was also the small fact that our supervising archdemon didn't want us to go. He liked the way we worked together. Incubus-succubus teams were hit or miss sometimes, but we were exceptional, and our superiors had taken note. It was good for our hellish careers but not for my morale. Bastien didn't see what my problem was. â€Å"Hell doesn't even need us here,† he told me one day, after I'd complained for like the thousandth time. â€Å"Think of it as a vacation. Hordes of souls are being damned here every day.† I walked over to the window of our shop and peered out onto the busy road, pressing my hands against the glass. Bicyclists and pedestrians moved past, everyone needing to get somewhere and get there fast. It could have been any ordinary weekday in Paris, but this was no ordinary day. Nothing had been ordinary since the Germans had occupied France, and the scattered soldiers in the street stood out to me like candles in the night. Bad simile, I thought. Candles implied some kind of hope or light. And while Paris had fared better than most people realized under Nazi rule, something in the city had changed. The energy, the spirit†¦whatever you wanted to call it, it had a taint to me. Bastien said I was crazy. Most people were still living their daily lives. The food shortages weren't as bad here as in other places. And after shape-shifting into Aryan nation poster children with blond hair and blue eyes, we were more or less left alone. Bastien was still going on about my glum mood while he moved about and straightened hat displays in my periphery. He'd chosen millinery as his profession for this identity, one that worked well for meeting well-to-do Parisian women. I played the role of his sister – as I so often did in other scenarios – helping with the store and keeping house for him. It was better than dance halls or brothels, which had been our previous occupations in France. â€Å"What about your friend?† Bastien asked me slyly. â€Å"Young Monsieur Luc?† At the mention of Luc, I paused in my dejected assessment of the world outside the hat shop. If I was going to talk about candles in the night, then Luc was mine. A real one. He was a human I'd met recently, working with his father – a violin maker. Their trade had suffered even more than ours, as the market for luxury items shriveled in these lean times. But Luc never seemed to let their financial woes affect him. Whenever I saw him, he was always cheerful, always full of hope. The weight of so many centuries of sin and darkness were starting to take their toll on me, and being in Paris only made it worse. Yet, Luc was a wonder to me. Being able to look at the world with such optimism, with such conviction that good would prevail†¦well, it was a foreign concept. One I was intrigued by. I couldn't stay away from it. â€Å"Luc's different,† I admitted, finally turning from the window. â€Å"He's not part of this.† Bastien snorted and leaned against the wall. â€Å"They're all part of this, Fleur.† Fleur was his long-time nickname for me over the years, no matter what identity I assumed. â€Å"I don't suppose you've slept with him yet?† My answer was to turn away again and remain silent. No, I hadn't slept with Luc. I wanted to, though. I wanted to with the instincts of a woman who had fallen for a man, as well as the craving of a succubus to consume the energy and taste the soul of someone so good. I had never hesitated before. This was the kind of thing I'd always sought out. It was even my job. But something inside of me was changing. Maybe it was these bleak times, but whenever I looked at Luc and saw that purity radiating from him – and his growing love and trust in me – I just couldn't do it. â€Å"He's coming by tonight,† I said at last, dodging the question. â€Å"We're going for a walk.† â€Å"Oh,† said Bastien. â€Å"I see. A walk. That's certain to impress Theodosia.† Theodosia was our archdemoness. I turned back around sharply, glaring at Bastien. â€Å"It's none of your business what I do!† I exclaimed. â€Å"Besides, if this is the ‘vacation' you claim it is, I shouldn't need to secure a good soul.† â€Å"Souls are falling left and right around here,† he agreed. â€Å"But you've still got to turn one in every once in a while. You can't spend the rest of your existence only going after bad ones.† I didn't speak to him for the rest of the day, and fortunately, business picked up quite a bit in the afternoon. It kept us both busy, though I counted down the minutes until Luc showed up that evening. He gave polite greetings to my â€Å"brother,† and then I hustled us out of there so that I wouldn't have to see the knowing look in Bastien's eyes. Luc could have passed for my brother too with his sunny golden hair. He always smiled when he looked at me, making small crinkle lines around the blue eyes I fancifully likened to sapphires. He held my arm as we passed through the evening crowd, filled with those going home after work or possibly seeking nighttime entertainment. He told me I looked beautiful, and we talked of other inconsequential things: the weather, neighborhood gossip, day-to-day affairs†¦ We ended up at a small city park that was a popular spot for others seeking evening strolls before curfew. We found a relatively secluded area among some trees and settled onto the grass. Luc had been carrying a small basket the entire time and revealed its contents: pastries and a bottle of wine. He didn't have extra money to throw around for that kind of thing, but I knew better than to protest. It was already done. Whatever else he'd had to sacrifice in return would be well worth it, as far as he was concerned. He had another surprise for me as well: a book. He and I were always trading novels back and forth, and as I lay down against the grass, skimming through the pages, a strange yet warm peace blossomed within me. â€Å"Next time you should bring your violin,† I said, setting the book down. â€Å"I want to hear you play again.† He stretched out beside me, his hand finding mine. We laced our fingers together and watched the sky grow purple. â€Å"Not out here,† he said. â€Å"I don't want a public concert.† â€Å"You'd charm them all,† I said. â€Å"The whole city would line up and dance at your command, just like the pied piper.† He laughed, the sound as golden as his hair or even the sun itself. â€Å"And then what would I do with them?† â€Å"Line them up and send them all away so that we can be alone.† â€Å"We are alone,† he said, laughing again. â€Å"Sort of.† I rolled to my side and leaned over him. Shadows from the surrounding trees enclosed us. â€Å"Alone enough.† I brought my lips down and kissed him, surprising both of us. I hadn't meant to do it. We'd never kissed before. I'd held myself back from him, earning all that chastising from Bastien. I could never bring myself to take Luc's energy and shorten his life. Yet, something came over me just then. It might have been my earlier gray mood or the feelings that were eerily like love within me. Whatever it was, being a succubus didn't matter just then. Well, it didn't until his energy started flowing into me. Our kissing grew more intense, our lips full of demand. His soul shone so brightly that even that one kiss was enough to taste his energy. It was glorious. My whole body thrilled to both it and his touch. He wrapped his arm around my waist, and without conscious thought, I began unbuttoning his shirt. He rolled me over so that I was the one on my back now and moved his mouth down to my neck. The knee-length skirts of this time gave him easy access to run his hand up my leg, and I pressed myself closer to him, pulling at his clothes while his hungry lips moved farther and farther down. All the while, that beautiful life filled me. I was drowning in it. When his lips reached the spot between my breasts, something seemed to jolt him to reality. He pulled up from me, running his hand over my hair as he looked down into my eyes. â€Å"Oh God,† he said. â€Å"We can't do this. Not now.† The mantra of moral men everywhere. â€Å"We can,† I said, surprised at the pleading in my own voice. It was the affection I felt for him speaking, not any agenda of Hell's. I wanted – needed – him to be closer to me. He sighed. â€Å"Suzette, Suzette. I want to. But I want us to get married. I can't do this – can't do this to you – unless I know you'll be my wife. It isn't right otherwise.† I stared up at him, uncertainty interfering with my desire. â€Å"Are you†¦are you proposing to me?† Luc thought about it for a moment and then grinned again, giving me another of those radiant smiles that never failed to make my heart race. â€Å"Yes. I guess I am. We'd have to wait a little bit – wait until I had more money. But when the war's over, things will get better.† This war's never going to be over, some gloomy part of me thought. But just now, that wasn't the real issue. His wanting to marry me was. It was impossible, of course. I could theoretically shape-shift so that I aged with him, all the while getting succubus sex on the side. Some succubi did that, having countless husbands over the centuries. Most didn't even stick around. They just disappeared. Their marital vows meant nothing. Looking at him now, at that burning love in his eyes, I felt my heart torn in two. If I said yes, he would wrap me up again and make love to me. If I said no, he wouldn't – not out of spite, but because of what was honorable. This could be so easy. Say yes. Promise I'd marry him and take him now. I could fulfill my heart's longing, my body's longing, and keep my good standing with Hell. I could leave after we were married. Or, easier still, break off the engagement. All I had to do was give him a dishonest â€Å"yes.† Sex to him wasn't right without that. Really, it was a wonder he didn't insist on waiting until marriage. The commitment was apparently enough. He believed in me. He believed I was a good, honest person. If I said I loved him and would be true to him forever, then he would accept that. Just say yes. But the words stuck in my throat. I couldn't lie to him. I couldn't let him find out how base I really was. And as his lingering life energy burned inside me, I realized I couldn't steal more from him. The guilt of what I'd done already was hitting me hard. It had only been the barest taste, but it had clipped time off of his life. And if I did back out of marriage after we'd had sex, he'd think what we'd done had been wrong. A sin. A black mark on his soul. I slid out from under him and sat up. â€Å"No,† I said. â€Å"I can't marry you.† His happy face remained unchanged. â€Å"It doesn't have to be now. And it doesn't even have to be†¦about this.† He gestured to where I'd just been lying in the grass. â€Å"Like I said, we couldn't get married for a while anyway.† â€Å"No,† I repeated, my heart sinking. â€Å"I can't†¦I can't marry you. Ever.† I can't hurt you. I care about you too much. I can't take your light from the world. He must have seen something in my face, something that drove home the truth of my words. That smile faded. The sun disappeared behind clouds. My heart broke. I hastily stood up, suddenly unable to look at him. What was wrong with me? I didn't know. All I knew was that I couldn't stay there. I couldn't stay there and see him hurting. If I did, I would start sobbing. As it was, I could feel tears starting to sting my eyes. â€Å"Suzette, wait!† I hurried away but soon heard him coming behind me. Even after my rejection, he didn't sound angry. He was concerned, worried about me. I hated that even more. I wish I'd driven him into a rage. But, no, even something like this†¦it would hurt him, yet he would respect both me and my choice. Which was why I had to stay away from him. Not just now, but always. I knew now that I couldn't be around someone I cared about. I couldn't stand the thought of causing pain to a loved one. I couldn't stand the thought of damning a good soul. Somewhere, somehow, after centuries of blithely harming others, I had gone horribly awry as a succubus. How? When? With Niccol? °? Was it just the gradual sum of all the lives and souls I'd harmed finally taking a toll on me? I was headed back for the hat shop. Bastien and I lived above it. I could still hear Luc following me, calling out to me that everything was okay. I knew if I made it inside, he wouldn't come barging in after me. He'd probably knock politely at the door but would go away if Bastien told him to. I took a shortcut, cutting behind some buildings off the main road. I knew the way well, but it was dark now, limiting my vision enough that I didn't see the soldier until I ran straight into him. He was standing so still and so solidly that it was like I'd accidentally run into one of the building's walls. I bounced back, and he caught me by the shoulder. â€Å"Easy there,† he said. His French had a heavy German accent but was articulated well. â€Å"You'll hurt yourself.† He was a giant of a man, young and not unattractive. I couldn't quite tell in the fading light, but his uniform made me think he was an officer of some sort. He was smiling down at me and hadn't let go of my shoulder. â€Å"Thank you,† I said demurely. I tried to step back gracefully, but his grip was strong. â€Å"You shouldn't be out here at all,† he added. â€Å"It's dangerous. Especially with curfew coming.† Curfew was nowhere near coming, despite the darkening sky. He looked me over as he spoke. My skirt had fallen back into place while running, but several buttons on my blouse had come undone with Luc and hadn't been fixed. It provided a pretty good vantage on my bra and cleavage. â€Å"My house is just over there,† I said. â€Å"I'll just – I'll just go now.† The hand on my shoulder stayed locked where it was, but his other hand had slipped through the opening in my blouse and was tracing the shape of my breast. Great. After all the deep and traumatic revelations I'd had tonight about the cursed life of a succubus, the last thing I needed was a Nazi feeling me up. Scratch that. There was something worse. â€Å"Let her go.† Luc's voice rang out behind me, and I winced. I'd hoped I'd lost him in the chase, but if he had seen me coming in this direction, he could have made a pretty good guess about which path I was taking home. â€Å"Walk away,† said the officer. â€Å"This has nothing to do with you.† Luc's fists were balled up. â€Å"Let her go,† he repeated. â€Å"I won't tell you again.† The officer laughed, but it was a harsh, terrible sound. â€Å"You won't tell me anything.† I tried my best to peer at Luc while still in that hard grip. â€Å"Go,† I told him. â€Å"It'll be all right. I'll be okay.† â€Å"Smart girl,† said the German. Luc lunged at him, and I was shoved out of the way as the two men grappled with each other. I stared in horror. Everything happened so quickly that my brain barely had time to even register what I was seeing. Luc was strong and fast, but the other guy was huge – and had a knife. I saw it flash briefly in what light was left, and then Luc's body went rigid. The officer stepped back, jerking the blade out of Luc's stomach as he did. I shrieked and tried to run toward him, but the Nazi's arm stopped me, grabbing hold of me once more. Luc's hands clutched at his stomach as blood flowed from it. He looked down at it in disbelief, like he was waiting for a punch line to reveal itself, and then he collapsed to the ground. I tried again to break free of my captor but couldn't. Luc's eyes gazed up at me, though his lips couldn't form any words as he lay there in that terrible agony, the life pouring out of his body. â€Å"There,† said the German officer, pulling me so that I was pressed against his chest. His knife had disappeared to wherever it had come from, and the hand that had held it – the hand that had stabbed Luc – was reaching under my shirt again. â€Å"Now there are no more distractions.† I heard Luc make a strangled sound as the officer ripped open the last of my buttons. Enough of my numbed shock wore off that I remembered I could fight back here. I could shape-shift to twice this guy's size and – Thunk. The Nazi's head lurched forward as something struck him from behind. His hold on me released, and he fell to the ground unconscious. Bastien stood behind him holding a hat block: a heavy, rounded wooden object used for constructing hats. â€Å"I'd know your scream anywhere,† he said. I had no time for his joking or to offer thanks. I dropped to my knees beside Luc and pulled off my blazer, frantically trying to use it to stop the bleeding. He was still conscious, and his eyes were on my face, still full of that hope and love that was so characteristic of him. Bastien knelt beside me, face solemn. â€Å"No human medicine can fix this, Fleur,† he said quietly. â€Å"I know.† I'd known as soon as I'd seen Luc fall. It was why I hadn't sent Bastien to get help. â€Å"Oh God. This can't be happening.† â€Å"It's†¦all right.† Luc's words were barely audible, and I had a feeling he was choking on blood. â€Å"You're safe†¦all that matters†¦Ã¢â‚¬  He coughed again, and this time I did see blood near his lips. â€Å"No, no,† I said. â€Å"It wasn't worth it. It wasn't worth it. None of this should have happened!† It was my fault. All my fault. Luc had come to save me from the German. I'd run into the German because I'd fled from Luc. And I'd fled from Luc because I'd suddenly latched on to a moral high ground and refused to have sex with him. If I'd just given in†¦if I'd just said I'd marry him and taken him like a succubus should have, this never would have happened. We would have been lying in the grass right now, naked in each other's arms. Instead, he'd died in this alley because of me, because of my weakness. I was a succubus who'd tried to act human – and I'd done a shitty job at both. Luc was beyond speech now. Everything was said with his eyes as he gazed at me, like I was some angel sent to carry him home. Bastien nudged me. â€Å"Fleur, he's going to stay alive a little while. You know how long stomach wounds take. It's agony.† â€Å"I know,† I growled, choking off a sob. â€Å"You don't need to tell me.† Bastien's voice was grave. â€Å"You can stop it. Ease his suffering.† I stared at Bastien incredulously. â€Å"What do you expect me to do? Go get that knife and finish him?† He shook his head. â€Å"He's only got a little life left, Fleur. Only a little. You won't need to do much.† I didn't get it right away. When I did, I felt my eyes go wide. â€Å"No†¦I can't†¦Ã¢â‚¬  â€Å"He dies regardless,† said Bastien. â€Å"You can make it faster†¦sweeter†¦Ã¢â‚¬  I was still shaking my head, but Bastien's words had penetrated. He was right. He was right, and I hated him because he was right. Turning from Bastien, I looked back at Luc, whose brow I'd been stroking with my hand. His gaze was still turned upward, still at me. A drop of water fell on his cheek, and I realized it was one of my tears. â€Å"Good-bye, Luc,† I said softly. It seemed like I should say a million other things to him, but I couldn't form the words. So, instead, I leaned down and brought my lips to his. I pressed against them, making full contact, though it had none of the animal passion from before. This was gentler. A whisper of a kiss. But as Bastien had said, it didn't take much. The beautiful, silvery sweetness of his life energy flowed into me. It was just as pure and perfect as before – and it was gone quickly. I took it into me and sat up, just as Luc exhaled his last breath. The eyes that had watched me so adoringly saw nothing now. I sat up and leaned against Bastien. â€Å"I killed him,† I said, no longer holding the tears back. â€Å"You brought him peace. You were his angel.† It was an eerie echo of my earlier sentiments. â€Å"No, this†¦I mean, before. He shouldn't have been out here. He's here because†¦because of me. If I'd slept with him, this wouldn't have happened. But I couldn't. I didn't want to hurt him†¦didn't want to taint him†¦and then this happened†¦.† Bastien put his arm around me. â€Å"If it makes you feel better, his soul won't be going to our people.† I buried my face in his shoulder. â€Å"This is my fault. My fault†¦I should have done what I was supposed to do. I was ready to – then he asked me to marry him and – damn it. I should have done it. I should have lied. It would have been better for everyone. I don't know how this happened†¦.† â€Å"It happened because you get too close to them,† said Bastien. He was stern but trying hard to be gentle. â€Å"Men like this†¦anyone like this†¦they enchant you, Fleur. You get attached and then you get hurt.† â€Å"Or I hurt them,† I murmured. â€Å"You need to stay indifferent.† â€Å"It's getting worse,† I said. â€Å"Every time, it's harder on me. I don't understand. What's happening to me? What's wrong with me?† â€Å"Immortality,† he said wisely. â€Å"Too many years.† â€Å"What do you know? You're younger than me.† Bastien helped me stand, though I was reluctant to let Luc go. â€Å"I know that you can't keep doing this. Listen to what I said: don't get attached to these good ones. No matter what you do, it won't end well.† â€Å"I won't go near the good ones at all,† I said in a small voice. â€Å"No more. I'm staying away from them altogether.† Bastien's kindly mien dropped. â€Å"That's ridiculous,† he scoffed. â€Å"Weren't you listening to me earlier? You can't go after immoral men for eternity. You'd get no energy. You'd have to do it every other day.† I looked down at Luc, Luc who had loved me and gotten killed for me. My fault. All my fault. â€Å"Never again,† I said. â€Å"I won't ever hurt anyone like that again.† When I returned to the box in the dark, I didn't need the Oneroi to enlighten me. All of that dream had been true – except for the last part. It had been a lie. I had continued to hurt people, over and over.

Hermann Hesse essays

Hermann Hesse essays Hesse became interested exploring how human mind works after undergoing psychoanalysis. He used, as subject of the story, having mental distress that leads to self-realization. The novel is about the story of the narrator named Emil Sinclair. It had been focusing Sinclair having disorder in his mind. He experienced working with his subconscious mind. It is a mental activity not directly perceived by your consciousness, from which memories, feelings, or thoughts can influence your behavior without you realizing it. It has been shown in the part where he dreamed of images or symbols that unable him to interpret that. Symbols and images are very important in psychology, specifically in the field of Carl Jung, a Swiss psychiatrist. Intellectual development occurs in Sinclair in the entire story. Sinclair thought of the two worlds, world of light and the outside world or the forbidden world which has a bad image of a place for him. He wants to live his life according to what he likes. In the story, he viewed his world, especially at home, as good and godly place. The characters like Demian, Fran Eva, Pistorius and Beatrice are only his imaginations. He continues to have a life with these characters with him as he went through. Beatrice affects his life very much even though they dont talk to each other. Pistorius is a musician and became a friend of him. Pistorius has belief that someone has within him but is not aware of that. And then, he met someone like Demian who became his friend that helped him a lot like the blackmailing of Kromer to him. Demian left for awhile when Sinclair transferred to the boarding house, primarily to be independent. In this situation, I can see that so many things bother him that time that he cant think of Demian. When he needed help, he starts searching for Demian. Demian left him because of the accomplishment of his mission that Sinclair decides for himself and acts o ...

House Calls - The Metaphors of Dr. Gregory House

House Calls - The Metaphors of Dr. Gregory House Before you can ask if theres a metaphor in the house, Dr. Gregory House will oblige: Have you guys heard any of my metaphors yet? Well come on, sit on grandpas lap as I tell you how infections are criminals; immune systems the police. Seriously, Grumpy, get up here: itll make us both happy.(Dr. Gregory House in the Mirror, Mirror episode of House, M.D.) Over the course of several years, the names of a dozen writers have appeared in the credits to the Fox TV program House, M.D. Each, it appears, owns a well-thumbed copy of the Merck Manual of Medical Information. And by now all must be collaborating on a new edition of the Dictionary of Metaphors. As regular viewers are aware, the shows deeply disturbed protagonist (played by Hugh Laurie) is inclined to deliver inflammatory eructations of festering figures of speech. Houses Medical Metaphors At times House relies on metaphors to translate complex medical conditions into language that his colleagues (and other true idiots) can understand. Cervical lymph node is a garbage dump. Very small onejust one truck comes, and it only comes from one home. Al Gore would be appalled. (97 Seconds)Saying there appears to be some clotting is like saying theres a traffic jam ahead. Is it a ten-car pile-up, or just a really slow bus in the center lane? And if it is a bus, is that bus thrombotic or embolic? I think I pushed the metaphor too far. (Euphoria, Part 1)Dr. House: You know, when the Inuit go fishing, they dont look for fish.Dr. Wilson: Why, Dr. House?Dr. House: They look for the blue heron, because theres no way to see the fish. But if theres fish, theres gonna be birds fishing. Now, if hes got hairy-cell, what else are we gonna see circling overhead? (Role Model)Dr. House: As far as youre concerned, the patient is Osama bin Laden, and everyone not in this room is Delta Force. Any questions?Applicant #11: Were protecting Osama bin Laden?Dr. House: Its a metaphor. Get used to it. (The Right Stuff)The tumor is Afghanistan, the c lot is Buffalo. Does that need more explanation? OK, the tumor is Al-Qaeda. We went in and wiped it out, but it had already sent out a splinter cella small team of low-level terrorists quietly living in some suburb of Buffalo, waiting to kill us all. . . . It was an excellent metaphor. Angio her brain for this clot before it straps on an explosive vest. (Autopsy) The liver is like a cruise ship taking in water. As it starts to sink, it sends out an SOS. Only instead of radio waves, it uses enzymes. The more enzymes in the blood, the worse the liver is. But once the ship has sunk, theres no more SOS. You think the livers fine, but its already at the bottom of the sea. (Locked In)Dr. Cameron: Idiopathic T-cell deficiency?Dr. House: Idiopathic, from the Latin meaning were idiots cause we cant figure out whats causing it. Give him a whole body scan.Dr. Cameron: You hate whole body scans.Dr. House: Cause theyre useless. Could probably scan every one of us and find five different doodads that look like cancer. But, when youre fourth down, 100 to go, in the snow, you dont call a running play up the middle. Unless youre the Jets.Dr. Cameron: I hate sports metaphors. (Role Model) But House is generally more intent on frightening than on edifying. As he once said: The point of metaphors is to scare people from doing things by telling them that something much scarier is going to happen than what will really happen. God, I wish I had a metaphor to explain that better. (All In) At other times the House metaphor is nothing more than a comic exercise in doctor-patient incivility. Once, after discovering that a young man had attempted self-circumcision with a utility knife, House snapped, Stop talking. Im going to get a plastic surgeon. To get the Twinkie back in the wrapper. House Metaphors About Life in General Of course, House himself is a walking, or rather limping metaphorhis crippled leg an emblem of his deformed spirit. And his acerbic metaphorical remarks may be read as symptoms of an undiagnosed malady. No, there is not a thin line between love and hate. There is, in fact, a Great Wall of China with armed sentries posted every twenty feet between love and hate. (Occams Razor)Dr. Wilson: Beauty often seduces us on the road to truth.Dr. House: And triteness kicks us in the nads. (Occams Razor)Lies are a tool: they can be used either for good orno, wait, Ive got a better one. Lies are like children: hard work, but theyre worth it because the future depends on them. (Its A Wonderful Lie)Dr. House: Nothing matters. Were all just cockroaches, wildebeests dying on the river bank. Nothing we do has any lasting meaning.Evan Greer: And you think Im miserable?Dr. House: If youre unhappy on the plane, jump out of it.Evan Greer: I want to, but I cant.Dr. House: Thats the problem with metaphors. They need interpretation. Jumping out of the plane is stupid.Evan Greer: But what if Im not in a plane? What if Im just in a place I dont want to be?Dr. House: Thats the other problem with metaphors. Yes, what if youre actually in an ice cream truck, and outside are candy and flowers and virgins? Youre on a plane! Were all on planes. Life is dangerous and complicated, and its a long way down. (Living the Dream) You know me. Hostility makes me shrink up like a . . .. I can’t think of a non-sexual metaphor. (Spin)You know its all nice when people start to dig these holes, but then they start to live in these holes and get angry when someone pushes dirt into those holes. Come out of your holes, people! (House vs. God)Dr. House: Im a night owl, Wilsons an early bird. Were different species.Dr. Cuddy: Then move him into his own cage.Dr. House: Wholl clean the droppings from mine? (Sleeping Dogs Lie) Every now and then, however, House finds himself on the wrong side of a metaphor, as in this exchange with a young patient: Dr. House: Are you going to base your whole life on who youre stuck in a room with?Eve the Patient: Im going to base this moment on who I am stuck in a room with! Its what life is. Its a series of rooms, and who we get stuck in those rooms with, adds up to what our lives are.(​ One Day, One Room) And how does House respond to the womans metaphor? As he must, by silentlyand literallywalking out of the room.

Individual Paper - Shadows of the leader Essay Example | Topics and Well Written Essays - 1250 words

Individual Paper - Shadows of the leader - Essay Example When leaders practice these, their followers will also be likely to do the same and as a result, the organisational culture will originate from the shadow cast above. This is especially because it is very difficult to try to correct one’s follower’s mistakes if you are their genesis. An example of how such leadership shadows can affect a company is Enron, it started n energy and network-providing firm that experienced unprecedented growth levels in the mid 90’s. After this, they hired the best business school graduates and the best talent in any field (Jickling, 2002). The culture was highly competitive with success being rewarded individually while failure was shunned. However, most of the focus was on the short rather than long-term success. As a result competition between individuals became acute and everyone more so the senior managers were ready to do anything to â€Å"make it big†, people were motivated by financial gain and consequently a culture of keeping business secrets and hiding losses in fictitious offshore ventures became rampant. Profits were inflated to keep the firm looking successful and even after it was nearly going bust, its shares were selling at $90 and the directors had assured the shareholders they would hit 120 although m ost of them sold off theirs. When Watkins, one of the executives blew the whistle on the illegal financial practices, the share price for the firm went down to $15 and the company declared bankruptcy resulting in millions of shareholder’s money being lost, careers and lives brought to ruin. This was caused by several of the shadows discussed above, by manipulating the accounting books, the leaders practiced deceit, which was copied by their juniors and became prevalent in the entire firm (Barreveld, 2002). Inconsistency was engendered in their tendency to say one thing to shareholders then do another, they promised increased share price but went on with practices

(1999). ‘Culturally competent research: an ethical perspective.’ Clin Psychol Rev. 19(1):4555. This article looks at the ethical guidelines and principles perspectives for providers on matters related to research on populations from ethnic minorities. Issues like informed consent presentation or reporting to those taking part in research, studies that are not appropriate on populations dominated by ethnic minority, researchers lacking diversity amongst themselves, and instrument assessment that are culturally insensitive are discussed in the article (Bobs, 1999). The article goes further to recommend certain criteria and responsibilities for cultural competence which include; involving the youth more in researches as concerned citizens as well as investigators, The recommendations generally address the bigger issue of failing to acknowledge persons in their differe nt cultural context. The article concludes by presenting what the ethical guidelines and principles imply on providers. The article is reliable as it fully covers cultural competence issues and goes further to offer recommendations on the same. The recommendations are detailed thus can be relied upon by any reader. Brach, C & Fraser, I. (2000). ‘Can cultural competence reduce racial and ethical health disparities?

Financial Analysis for Kroger Co Research Paper

Financial Analysis for Kroger Co - Research Paper Example For an industry like Kroger’s, the most important factor for consumers is price. The products available in supermarkets are not differentiated and therefore they cannot be advertised heavily. Much of the advertisement that is done is carried out on the basis of attracting families to shop at Kroger because it is cost effective to do so. Apart from being cost effective Kroger also has products of high quality which makes it popular among American consumers. Kroger Co. has 42 manufacturing plants and including dairies, beverages and meat plants and all of these plants are of the highest standards. In the recent years there has been a tremendous increase in the fuel prices and the recent financial meltdown has made things worse for many industries including Kroger. The rise in fuel prices caused an increase in costs of the products sold by Kroger. Kroger is both a manufacturing company and a retail outlet and was therefore heavily affected by the increase in cost of fuel and othe r raw materials. According to Porter, there are 3 strategies a company can adopt to become competitive and Kroger has undertaken the â€Å"cost leadership† strategy which helps to differentiate it from the rest of the supermarket chains. The continuing increase in fuel prices will prevent Kroger from increasing costs and the strategy and it would be difficult to achieve goals. Kroger can shift to alternative sources of energy and reduce its costs that way. The recent financial meltdown meant that the demand for grocery products decreased to a large extent. In the past consumers would buy gourmet foods and other items from supermarkets but due to the credit crises that has decreased. Consumers have become more price conscious and buy only items that are necessary. Such a decrease in spending has affected the entire industry at large and profit margins have gone down since the past. In 2009 there was a 60.5% drop in consumer confidence index. (Zahorsky) Kroger has been taking a dvantage of the opportunities and developed its own brand called â€Å"Private Selection† and manufactures its own products under this brand name. Consumers often prefer branded products in place of national and Kroger has been successful in understanding this need. In 2009 Kroger earned around $1 billion in sales from this brand alone and the sales continue to grow today (Zahorsky). Such a step by Kroger would not only help the company but the industry as a whole. Liquidity Ratio Current ratio of Kroger Co. for the financial year 2012: = = 0.804 Current ratio for the year 2012= 0.804:1. The current ratio for the industry is around 0.8 which is the same as Kroger (Kroger Co. Ratios, 2012). The

Legal Issues in Sports Gambling Essay Example | Topics and Well Written Essays - 2750 words

Legal Issues in Sports Gambling - Essay Example With the advent of increased online gambling activities, there had been confusion because a majority of laws applied to gambling in sports and other forms of bet taking were in use long before the internet came into widespread use and were at the discretion of states. Further, laws relating to cyberspace have been hard to craft while older laws are open to broad interpretations in this context. Bills’ seeking to create laws to regulate online gambling has mostly ended in failure. However, Illinois passed legislation which strictly bars advertising of online casinos in the state (Illinois Gambling Laws, 2012). In reference to the Gambling and Related Offences 2012 (US), section 28(1) one is said to commit gambling offence when, he or she makes a wager upon the result of a game. Brief history of sports gambling. Ever since, sporting activities started, people have had the urge to bet on the outcome. Nowhere else is gambling as widespread as in the United States. Thompson (2001), in his research identified the founding fathers of the United States as natural risk takers; therefore the attraction to take part in all forms of gambling was rather inherent. Humphrey (2012), in his research, stated that, in the initial days of United States, the colonists used to gamble on anything ranging from bare-knuckle brawls to cockfights and makeshift horse races.... Thompson (2001) confirmed many colorful characters and factors have played a role in the  growth  of sports gambling, but what is  obvious  is that sports gambling are here to stay despite efforts by various governments’ attempts to curtail its  growth. Sometime back, a sport betting was just a  negligible  part  in  human, social life, but nowadays it runs from the professional bettor, the middle class  family  to the common man on the street (Ziming  and Shaffer, 2009). The effect of this has been that professional bookmakers and gamblers have resulted to bribery of participants and other  uncouth  activities. Horse racing was the first sport which recorded  widespread  bet  activity  due to its increased popularity especially in the United Sates. During the initial years, this was a  game  for the upper class, but after the  end  of civil war, horse tracks appeared and dotted eastern landscapes attracting bettors from every econom ic sector in United States (Thompson, 2001). The peak of horse racing was in 1920s and  decline  began in 1930s. Currently, Unlawful Internet Gambling Enforcement Act 2006 (US) has  section  5363 and 5366 which has criminalized taking of money from bettors by online gaming website operators but excludes online betting on horse racing activities from its list of illegal gambling activities. However, these bets must be  legal  at the two ends of online connection (Humphrey, 2012). Formation of professional leagues, they diverted attention of gamblers and made a majority of them  abandon  horse race betting for other areas such as professional baseball. Use of  pool  cards’ became  common  especially in the urban areas of the East. These  pool  cards were similar to the present

Sulfur recovery processes Essay Example | Topics and Well Written Essays - 750 words

Sulfur recovery processes - Essay Example gas treatment system, where the effluent gases that remain from the purification process are used to oxidize sulfur into sulfur dioxide, instead of being released to the atmosphere to cause pollution. Most significant is that this process yields high quality sulfur, making it a good source of this valuable chemical (Kohl & Nielsen, 1997). However, the air pollution controls that have been put in place have made the Claus process even more expensive, since some installations that prevent air pollution have to be made, despite the fact that they may not be economical at all. The problem of Claus Process is added to, by the fact that it is unable to fully convert hydrogen sulfide into elemental sulfur, due to some equilibrium limitations. Therefore, no matter how well the emission of sulfur compound is controlled, the process ends-up releasing relatively high quantities of the air pollutant than is actually acceptable (Kohl, 1997). Thus, most of the times, the process requires to be supplemented with specific processes meant to remove the sulfur residue, which ensures that any excess sulfur emission from the process is cleaned-up. Claus process occurs in two forms, referred to as the straight-through process and the split-flow process. The processes are differentiated by the fact that, while in the straight-through process gas is fed through the reaction furnace, it is fed directly into the major catalytic reactor through bypassing the furnace, in the split-flow process (Kohl & Nielsen, 1997). The choice of the process to be used between these two sulfur purification processes depends on the content of hydrogen sulfide in the gas to be purified, and whether the gas contains hydrocarbons. If the gas to be purified contains hydrocarbons, then, the straight-through process is opted for, while the split-flow process is applied where the gas does not contain large quantities of hydrocarbons (Kohl, 1997). There are some fundamental aspects of the Claus process that should

The Heiress Essay Example | Topics and Well Written Essays - 250 words

The Heiress - Essay Example By giving the buttons to Morris, I believe she was ending the relationship between her and Morris. I think the button symbolizes greed by Morris, as well as generosity of Catherine. This is a decision she makes with finality. The effect of bringing Catherine as a bold lady who was timid at the beginning of the play creates more realism to the play. I believe the actions of Catherine in the last scene were more definitive on liberation rather than an absolute bitterness reaction. She also appears to have begun to resemble her father through understanding the reality of what she went through. From the body language, voice and attitude, it becomes apparent that Catherine completely transformed at the end of the play. This play empowers women. It highlights on liberation from stifling relationships. Catherine appears strong enough to lead her own life without Morris as she ascends with a dreamy smile. The desertion of Morris and Catherine’s father’s rejection of him makes it conclusive that Catherine’s father was

The problem of Claus Process is added to, by the fact that it is unable to fully convert hydrogen sulfide into elemental sulfur, due to some equilibrium limitations. Therefore, no matter how well the emission of sulfur compound is controlled, the process ends-up releasing relatively high quantities of the air pollutant than is actually acceptable (Kohl, 1997). Thus, most of the times, the process requires to be supplemented with specific processes meant to remove the sulfur residue, which ensures that any excess sulfur emission from the process is cleaned-up. Claus process occurs in two forms, referred to as the straight-through process and the split-flow process. The processes are differentiated by the fact that, while in the straight-through process gas is fed through the reaction furnace, it is fed directly into the major catalytic reactor through bypassing the furnace, in the split-flow process (Kohl & Nielsen, 1997). The choice of the process to be used between these two sulfur purification processes depends on the content of hydrogen sulfide in the gas to be purified, and whether the gas contains hydrocarbons. If the gas to be purified contains hydrocarbons, then, the straight-through process is opted for, while the split-flow process is applied where the gas does not contain large quantities of hydrocarbons (Kohl, 1997). There are some fundamental aspects of the Claus process that should

Institutional Racism Impact on Education, Employment, and Health Essay

Institutional Racism Impact on Education, Employment, and Health - Essay Example As Ibrahim states "in spite of the attempts to equalize educational opportunity for all groups, research on immigrant children's successful intergration into the education system shows that there is a high drop-out rate among these students."(Ibrahim, insert page number here) For this reason the Second National Institute-Conference hold in Miami, Florida in 1974, took a penetrating look at Institutional Racism and the Impact on Health Care Delivery through in-depth focus on institutional racism. Some Black nurses interacted together in examining and exploring its impact on the health status of the Black consumer followed by planning and developing strategies for affirmative action approaches designed to make a meaningful impact toward change. As for in the sector of employment it has been seen time and again that there is a system working as an open secret that discriminate colored or immigrants with job opportunity and salary. This discrimination is based on not only color or political distinction but also is depended upon other factors like class, creed, cast, religion, sex and even ideology. Everything that has been stated above is a part of an ideology that the racist believe to be of ultimate truth.

The Body Farm Essay Scarpetta’s actions show that she is in good mental and physical shape. For example, every â€Å"morning [she] woke up† and she â€Å"went out for a run in the brisk, moist air† (159). In this quote the author tells the reader that Kay Scarpetta runs on a daily basis. This means that along with being physically fit, she is able to allow her mind to push herself every morning to get up and go running. In addition, Kay Scarpetta was wondering â€Å"if there might be some other explanation for why she chosen this route† (113). In this quote the reader can conclude the Dr. Scarpetta is logically trying to find a reason for why she chose the route that she did. Additionally, the author describes Kay and how there is a â€Å"fierce battle being fought in [her] mind† (168). As a result, Kay’s mind is becoming stronger. Good mental and physical shape is portrayed by Kay Scarpetta’s actions. By examining Dr. Kay Scarpetta’s appearance the reader can see that she is a wealthy person. For instance, the â€Å"black flight suit† was recognizable to Kay Scarpetta (52). In this quote Kay Scarpetta was able to recognize this specific flight suit since she is able to afford to fly on airplanes a lot. For example, Kay â€Å"still wasn’t certain why [she] had bought [her] charcoal Mercedes 500E† (169). In this quote the author is stating that Kay doesn’t know why she really did buy the car. This shows that she is wealthy because if she wasn’t then why would she randomly buy a new car for a reason that was unknown. Additionally, Kay would wear a â€Å"boldly colorful warm-up suit [she] wore on the occasions when [she] played tennis† (170). This means that she has enough money to buy a warm-up suit for only whenever she plays tennis. Dr. Scarpetta could be thought as a wealthy person by examining her appearance. Kay Scarpetta’s speech shows that she is well educated. To illustrate that she is educated Dr. Kay Scarpetta said that if â€Å"you make those casts, and you’re going to find the impression on the shoulder’s going to match the impression back there on the road† (261). This quote informs the reader that Kay Scarpetta is a well educated woman in this field. The reader can conclude that Kay had special training of some sort to be able to know about how to make and find impressions. In addition, Dr. Scarpetta found out that the â€Å"Bureau knows that I couldn’t have been Lucy’s thumb scanned into the biometric lock system† (373). In this quote the author mentions the biometric lock system. That lock system must be familiar to Dr. Scarpetta since she knew about it and could tell that it was not Lucy’s thumb print. For example, Kay Scarpetta is giving the autopsy Emily and she notices â€Å"the visceral pleura shows scattered petechiae along the interlobar fissures† (99). This means that Kay went to medical school because she knows these terms that only a medical examiner would know. By examining Dr. Scarpetta’s speech it informs the reader that she is well educated. Dr. Kay Scarpetta has several different personalities. For instance, Dr. Scarpetta â€Å"began to dread working late at night† (2). This quote is describing how she is not working as hard as she used to. In addition, Kay Scarpetta â€Å"could not stop wondering what more [she] could have done† (4). This means that Kay Scarpetta was working really hard to try and figure something out. This is another side of her personality. Additionally, Dr. Kay Scarpetta â€Å"got [her] revolver out of the briefcase† (327). In this quote she is taking out a revolver and is thinking about using it, but previously she mentioned that she does not like to use guns. Ms. Scarpetta has multiple personalities.

Simulation of the ALOHA protocol

Simulation of the ALOHA protocol Abstract-The present essay is a tutorial on the OMNeT++ simulation environment, through the analysis of the known ALOHA protocol. The model implements the ALOHA random access protocol on the Link layer, and simulates a host to server instant broadcast. ALOHA is rather simple yet convenient to demonstrate the potential of OMNeT++ in simulating wireless protocols. The final part evaluates the pure and the slotted ALOHA variations, in regard to the theoretical models. Introduction OMNeT++ is a discrete event simulation (DES) environment, developed by Andras Varga as public source, and is accompanied by Academic Public License, which means that it is free for nonprofit academic use. The intention behind OMNeT++ was the development of an open source generic simulation environment, not exclusively dedicated to network simulations as the more known ns-2, or the commercial Opnet. The environment offers instead, a generic and flexible platform to develop simulation frameworks dedicated to complex IT systems, as wireless and sensor networks, the classic IP and IPv6 stacks, queuing networks, optical networks and various hardware architectures. Typical example of a framework that provides simulation components for IP, TCP, UDP, Ethernet and MPLS, is the INET Framework and the MiXiM, which is an aggregation of several frameworks for mobile and wireless simulations. The OMNeT++ ver. 4.0 is built on the known Eclipse CDT ver. 5.0, and uses most of its resources. It is offered for Windows and Linux operating systems. The core of the models is coded in C++, in Linux uses the gcc compiler and in Windows uses the MinGW port for the gcc suite. There is a commercial version called OMNEST, with no significant accessories than the open version, except the optional use of the native Visual C++ compiler for the Windows platform. The ALOHA protocol was one of the oldest random access protocols, invented by Norm Abramson in 1969. The first wireless network, implementing packet switching over radio, used the pure ALOHA variation, have initially established in Hawaii. Later Abramson interfaced the ALOHAnet with the ARPAnet, the primitive form of internet. The ALOHA have inspired the creation of CSMA/CD and the birth of Ethernet. Finally, the random access protocol has evolved to contemporary CSMA/CA, the MAC layer of Wi-Fi. The slotted ALOHA and the later pure ALOHA have simple implementations, appropriate for simulation. It uses only the host to server broadcast instant, but is adequate to calculate the maximum channel capacity and demonstrate some other interesting attributes, as well. OMNeT++ DESCRIPTION The Structure of Models OMNeT++ is based on C++ programming and follows the object-oriented approach with classes and class instances, the so-called objects. The simulation model consists of modules, which communicate by message passing. The core element is the simple module, which is written in C++, and constitutes an instance of a module type from the simulation class library. The next structural element in the hierarchy is the compound model, which is formed from simple modules or other compound models. Every module, simple or compound, has ports to communicate with the external environment, called gates. Gates could be bidirectional or could be restricted to input or output. Modules are connected through their gates via connections and they communicate by exchanging messages, via these connections. The block diagram in Fig. 1 depicts the internal module structure according to the declared hierarchy, in OMNeT++. The connections are limited within the module range but the message exchange can be established across hierarchy levels. This is applicable in the case of modeling wireless systems and the simulation of ALOHA stations will make use of it. Otherwise, messages are traveling through the chain of connections. Modules have parameters, which are used to pass initialization data during the initiation of the simulation. The compound models can pass parameters to the contained sub-modules. The final model which contains the aggregate of the modules is called network model, is represented as a class and each simulation run is executed on an instance of this class. The NED language The structure of the simulation in OMNeT++ is based on the network description language (NED). The NED includes declarations for the simple modules and definitions for the compound modules and the network model. The language programming is accomplished by the integrated graphic editor, as shown in Fig. 2 or the text editor, as shown in Fig. 3. Both editors are producing equivalent code, and the programmer can switch from one another without any derogation. The programming model The typical code development includes the following steps: The programmer creates the network model, by creating the appropriate network_name.ned file, using the IDE. The NED file describes the network name and the topology, which are the names of the sub-modules, simples and compounds. Every sub-module should have its own module_name.ned file, which includes the parameter declarations and other meta-data. As mentioned, the behavior of every simple module is expressed in C++, so there should be two specific files, the module_name.cc and the module_name.h, for every simple module. These files are compiled during simulation execution by the supporting C++ compiler, and linked with the simulation kernel and libraries. The programmer usually tests the behavior of the simulation model according to different inputs. These could be entered manually by the user, during simulation execution, or could be included in a configuration file. Generally, there is a special type of file the omnetpp.ini that contains these parameters and the rest of the building blocks, to support user interaction. The IDE includes an editor for the initialization files, which can switch between form view, as shown in Fig. 4, and source view, as shown in Fig. 5. The two fields are equivalent. There are two fundamental methods to develop C++ code for programming the simple module behavior: The co-routine based and the event processing function. In the first approach, every module executes its own threat of code, which is activated every time it receives a message from the simulation kernel. In the last approach, the simulation kernel calls the module function, having the specific message as argument. Prior to main() function execution, an initialization function declares variables and objects and before program termination, a finalization function saves the data logged during simulation, and produces histograms. OMNeT++ Architecture and Potentiality The following Fig. 6 presents the internal logic structure of OMNeT++. The first block is the model component library, which the programmer develops in C++, and contains the compiled code of simple and compound modules. The simulation kernel and the class library (SIM) instantiates the modules and build the concrete simulation model. The user interface libraries (Envir and Cmdenv or Tkenv) provide the simulation environment, which defines the source of input data, the sink of simulation results and the debugging information. It controls the simulation execution, visualization and animation. Cmdenv provides only command line and text mode input-output, and it is more appropriate for batch simulations. Tkenv is the graphical user interface (GUI) of OMNeT++. It provides automatic animation, module output windows and object inspectors. The following Fig. 7 depicts an active simulation output through OMNeT++/Tkenv. OMNeT++ includes very powerful tools to visualize the interaction among modules. A sequence chart diagram provides a way to inspect the timing of the events during simulation by extracting data from an event log file. During the finalization routine, the logged data are saved to specific result files, the vectors in network_name.vec and the scalars in network_name.sca files, respectively. For the result analysis, OMNeT++ produces the analysis file network_name.anf, which contains aggregated data in vectors and scalars plus any histograms, created during the final stage. All the types of data can be further processed by using pattern rules, in datasets and charts section, to produced advanced charts and graphs. In the ALOHA simulation most of the available choices are used for demonstration. Aloha Simulation Background Theory The slotted ALOHA is the most simple random access protocol. The transmitting station always broadcasts at the full rate R of the channel. The transmission initiates at the beginning of the slot, which is common for the aggregate of the stations. If two or more stations transmit simultaneously, then the condition is called collision and all the stations involved, after a random time different for each, retransmit the frame until successful delivery. The procedure is presented at the following figure: The slotted ALOHA protocol allows each station to transmitat at the channels full speed R, but requires slots to be synchronized in all the stations, something not nessesary for the unslotted or pure ALOHA. The following assumtions are made to simplify simulation: The source generates single frames of length L bits. The inter-arrival times between frames follow exponential distribution. If R bps is the capacity of the wireless link then the slot time is set equal to the transmission time of each frame, which is: tframe=LR sec. All nodes are synchronized and transmit frames only at the beginning of a slot. If a node has a new frame to send, it waits until the beginning of the next slot. If two or more frames collide, then their hosts retransmit after random time, following exponential distribution. If there is no collision, then the node transmits its next frame following exponential distribution. I define N the number of stations operating the slotted ALOHA protocol and p the probability of each station to transmit in the next slot. The probability for the same station to do not transmit in the next slot is then 1-p, and for the rest of the stations is 1-pN-1. Therefore, the probability for a station to have a successful transmission during the next slot is to transmit and the rest of the stations to do not transmit, so it is p1-pN-1, and because there are N stations, the probability that an arbitrary node has a successful transmission is Np1-pN-1. A slot where a single station transmits is called a successful slot. The efficiency of slotted ALOHA is defined as the long run fraction of successful slots, which is: Ep=Np1-pN-1 (1) To find the maximum efficiency, we seek p* that maximizes (1). Then: Ep=N1-pN-1-NpN-11-pN-2=N1-pN-21-p-pN-1 If Ep=0 then p*=1N . Using this value, the maximum efficiency is: Ep*=N1N1-1NN-1=1-1NN-1=1-1NN1-1N (2) For a large number of active stations, the maximum efficiency accrues from (2) as N approaches infinity: limNEp*=limN1-1NNlimN1-1N=1e1=1e=0.368 (3) From (3), the maximum efficiency of slotted ALOHA is 0.368 or 36.8% The unslotted version or pure ALOHA protocol does not have the restriction of slot synchronizing, and the station is able to broadcast when a new frame is available. So pure ALOHA is a full-decentralized random access protocol. When a transmitting station detects a collision, after completing the transmission, it retransmits the frame with probability p. If it chooses to postpone the transmission for a single frame transmission period tframe=LR sec, then the probability is (1-p). The figure below depicts transmissions and collisions in the unslotted channel. The maximum efficiency of pure ALOHA protocol is calculated similarly as the slotted ALOHA. The only difference here is that the rest of the stations should have not begun transmitting before and should not begin during the broadcast of the given station. The probability that the rest of the stations remain idle is 1-pN-1 and the probability that they remain idle is 1-pN-1 again. Therefore, the probability that the given station will have a successful transmission is p1-p2N-1. Again, we seek the value of p* that maximizes (4), which is the probability of successful transmission for the sum of the N stations. Ep=Np1-p2N-1 (4) Ep=N1-p2N-2-Np2N-11-p2N-3=N1-p2N-31-p-p2N-1 If Ep=0 then p*=12N-1 . Using this value the maximum efficiency is: Ep*=N2N-11-12N-12N-1 (5) From (5), the maximum efficiency accrues as N approaches infinity, which is: limNEp*=121e=12e (6) From (6) I assume that the maximum efficiency, for the pure ALOHA protocol, is 0.184 or 18.39%, the half of slotted ALOHA. Another useful diagram is in Fig. 10. It depicts the apparent superiority of slotted ALOHA over the pure ALOHA protocol, despite the limitations that turn it to non-functional. The normalized total traffic is the aggregate traffic, which generated by the source of the station, divided by the channel capacity R and the normalized throughput ? is the average successful traffic (non-collided) divided by R. The slotted ALOHA achieves double throughput than the pure ALOHA and achieves its maximum efficiency when the generated traffic rate equals the channels capacity R. The pure ALOHA although, achieves its maximum efficiency when the generated traffic equals to R/2. Model Development NED language The following paragraphs describe the process of creating a functional model for the simulation of ALOHA protocol in OMNeT++. The object of simulation is to study the behavior of the ALOHA model and to confirm the theoretical values of maximum efficiency for pure and slotted ALOHA. The ALOHA random access protocol is peer based and does not use a server-client architecture. It is convenient to study the effect of collisions and random retransmissions only in the case when one host is receiving (becomes server) and the rest of the hosts are transmitting. The first step is to develop the NED code that describes the network Aloha. The following Aloha.ned file creates the Aloha network, which consist of simple modules, one called server and a number of hosts, equal to numHosts parameter. The txRate defines the transmission rate R, of the wireless channel, and slotTime defines the type of protocol. Zero means pure ALOHA and 100ms defines the slot time length. The parameter @display selects a background image, taken from the library. network Aloha { parameters: int numHosts; // number of hosts double txRate @unit(bps); // transmission rate double slotTime @unit(ms);// zero means no slots (pure Aloha) @display(bgi=background/terrain); submodules: server: Server; host[numHosts]: Host { txRate = txRate; slotTime = slotTime; } } The following Server.ned file describes the servers simple module. It loads an image for the server icon and defines a gate of input type (in), with which it is not necessary to establish a connection. It can receive a message directly from a host via @directIn, something that is usual to wireless simulations. simple Server { parameters: @display(i=device/antennatower_l); gates: input in @directIn; } The following Host.ned describes the hosts simple module. It loads a set of parameters from the omnetpp.ini file, the radioDelay, which is the propagation delay over the radio link, pkLenBits, which is the length of the frame, and iaTime, which is the random inter-arrival time, following exponential distribution. The rest of the parameters, txRate and slotTime, are loaded in Aloha.ned, during sub-module instantiation. simple Host { parameters: double txRate @unit(bps); // transmission rate double radioDelay @unit(s);// propagation delay of radio link volatile int pkLenBits @unit(b); // packet length in bits volatile double iaTime @unit(s); // packet interarrival time double slotTime @unit(s); // zero means no slots (pure Aloha) @display(i=device/pc_s); } Configuration The most critical file is the configuration file omnetpp.ini. It stores the values of the parameters that are loaded in the NED parameter fields. When declaring on the [General] field that Aloha.slotTime=0, is presets globally the pure ALOHA protocol. Similarly, the Aloha.numHosts=20 defines the number of hosts to be 20, the Aloha.txRate=9.6kbps defines the R to be 9600bps. The last definitions load the parameters of Aloha model and consequently the parameters of the simple modules that Aloha model controls, which are the server and the host modules. The definitions Aloha.host[*].pkLenBits=952b and Aloha.host[*].radioDelay=10ms load directly the parameters pk.LenBits and radioDelay on every host submodule, respectively. [General] network = Aloha #debug-on-errors = true #record-eventlog = true Aloha.numHosts = 20 Aloha.slotTime = 0 # no slots Aloha.txRate = 9.6Kbps Aloha.host[*].pkLenBits = 952b #=119 bytes, so that (with +1 byte guard) slotTime is a nice round number Aloha.host[*].radioDelay = 10ms [Config PureAloha1] description = pure Aloha, overloaded # too frequent transmissions result in high collision rate and low channel utilization Aloha.host[*].iaTime = exponential(2s) [Config PureAloha2] description = pure Aloha, optimal load # near optimal load, channel utilization is near theoretical maximum 1/2e Aloha.host[*].iaTime = exponential(6s) [Config PureAloha3] description = pure Aloha, low traffic # very low traffic results in channel being idle most of the time Aloha.host[*].iaTime = exponential(30s) [Config PureAlohaExperiment] description = Experimental mutliparameter demostration repeat = 2 sim-time-limit = 90min **.vector-recording = false Aloha.numHosts = ${numHosts=10,15,20} Aloha.host[*].iaTime = exponential(${mean=1,2,3,4,5..9 step 2}s) [Config SlottedAloha1] description = slotted Aloha, overloaded # slotTime = pkLen/txRate = 960/9600 = 0.1s Aloha.slotTime = 100ms # too frequent transmissions result in high collision rate and low channel utilization Aloha.host[*].iaTime = exponential(0.5s) [Config SlottedAloha2] description = slotted Aloha, optimal load # slotTime = pkLen/txRate = 960/9600 = 0.1s Aloha.slotTime = 100ms # near optimal load, channel utilization is near theoretical maximum 1/e Aloha.host[*].iaTime = exponential(2s) [Config SlottedAloha3] description = slotted Aloha, low traffic # slotTime = pkLen/txRate = 960/9600 = 0.1s Aloha.slotTime = 100ms # very low traffic results in channel being idle most of the time Aloha.host[*].iaTime = exponential(20s) A selection of the SlottedAloha2 configuration overrides the value of slotTime with Aloha.host[*].slotTime=100ms, which fixes the slotted ALOHA protocol with slot time to 100ms. The Aloha.host[*].iaTime=exponential(2s) sets the frame inter-arrival time on every host to follow exponential distribution, with mean time equals to 2 seconds. The Config option PureAlohaExperiment exploits the OMNeTs capabilities of organizing different experiments with simple repetition declarations. The statement Aloha.numHosts=${numHosts=10,15,20} declares three (3) repetitions having 10, 1 and 20 hosts respectively. The statement Aloha.host[*].iaTime=exponential(${mean=1,2,3,4,5..9 step 2}s) declares seven (7) repetitions, with interarrival times equal to exponential distribution and means, 1, 2 ,3, 4, 5, 7 and 9, respectively. The repeat=2 statement doubles the number of runs, so finally the available choices will be 2x3x7=42 from 0 to 41 optional runs. The statement sim-time-limit=90min constrains the simulation time to 90 minutes. C++ model coding The simple modules Host and Server are based on C++ programming. The relevant host.cc, host.h, server.cc and server.h, which are included entirely in the appendix section, implement the model behavior during simulation by exchanging messages directly one-another or with the simulation kernel. The following Fig. 11 is a design- level class diagram, describing the basic relationships among network module Aloha and simple modules, Host and Server. The two last, inherit from cSimpleModule simulation class library, and redefine the basic methods initialize(), handleMessage(), activity() and finish(), according to the desired function. The Aloha network model comprises of several Host objects and one Server, so it keeps an aggregation association with Host and Server classes. It passes also to them some parameter values, some declared in the omnetpp.ini file and some taken from user dialog form. The Host module keeps an one-way association with Server because every Host declares a Server object in the attribute field, in order to send a direct message (pk) later, by calling the sendDirect() function. The scheduleAt() function programs the kernel to send the Host an endTxEvent message when the transmission ends. This is represented by the self-association. Similarly, the Server module programs the kernel to send the Server an endRxEvent, when the reception of the message sent from Host finishes, and is represented as the self-association. The module code is cited commented in the appendix. Here, I will explain the finish() function of the server module, because it creates the result reports, necessary for the exploitation of the simulation. void Server::finish() { EV

The Future of NASA   Ã‚  Ã‚  Ã‚  Ã‚  One hundred years from now, NASA's space program will not be so far advanced that people will be able to beam around the Universe or travel through time. However, unless something goes terribly wrong with the world, it is expected to advance tremendously. New, high-tech designs for rockets will make them more environmentally safe. Rockets will also be recycled and reused. Systems retrieving parts of rockets that are today, left behind in space, will be created. Astronauts will be well on their way to exploring Mars from a hands-on perspective. Because of the overpopulated Earth, scientists may even be considering ways to alter life on Mars, so that people would be able to live there some day.   Ã‚  Ã‚  Ã‚  Ã‚  Some products developed in NASA's space program that we now incorporate in our daily lives include the vacuum cleaner, pacemaker, pens that can write upside-down, and the zero-gravity training system. The vacuum cleaner was originally a great tool for astronauts in outer space. It is now a very helpful tool for cleaning our homes. The pacemaker is a form of life-support on spacecrafts, helping astronomers' hearts pump while they are outside of the Earth's atmosphere. It is used, on Earth, for those who's hearts have problems with pumping blood. Pens that write upside-down are used in space, where there is no gravity and writing with pens would otherwise be impossible. They are convenient tools on Earth when we are trying to write on vertical surfaces. A zero-gravity training system is used to help astronauts become more comfortable with the conditions in space. It is used in places such as Sportsland, for kids to twirl around in.   Ã‚  Ã‚  Ã‚  Ã‚  In the future, telephones with picture screens, much like those used to see astronauts in space with, will become common on Earth.

Civil Disobedience By Thoreau

Philosophers, historians, authors, and politicians have spent centuries pondering the relationship between citizens and their government. It is a question that has as many considerations as there are forms of government and it is rarely answered satisfactorily. A relatively modern theorist, author Henry Thoreau, introduced an idea of man as an individual, rather than a subject, by thoroughly describing the way a citizen should live many of his works. He indirectly supplements the arguments he presents in his essay Civil Disobedience through a comprehensive selection of adages found in his other works. In articular, the phrases  «A simple and independent mind does not toil at the bidding of any prince » and  «To be awake is to be alive. I have never met a man who is quite awake » support many of the arguments in Civil Disobedience because they help to explicate the complex ideas Thoreau presents. The phrase  «A simple and independent mind does not toil at the bidding of any prince » regards the responsibilities of a man to his own consciousnessit is a duty that can not be revoked by any form of tyrant. Rather than hinting at a type of anarchy, this statement merely describes each mans duty to performing justice in all his actions. This does not refer to any  «mans duty to devote himself to the eradication of any, even the most enormous wrong; he may still properly have other concerns to engage him; but it is his duty, at least, to wash his hands of it, and, if he gives it no thought longer, not to give it practically his support » (681). The term  «simple » does not refer to an underdeveloped sense of morality; it describes a state of mind in which the concept of justice is so defined that contradictions cannot exist. To toil, as it is presented in this quotation, means to sacrifice ideals for the sake of conformity or law. The only real power the State holds over any individual is the promise of brute force; it  «never intentionally confronts a mans sense, intellectual or moral, but only his body, his senses » (687). Therefore, many acts the State requires will be unjustthey can and will force a man to slave for the sake of an ordeal he does not believe in. As Thoreau notes in Civil Disobedience,  «a wise man will only be useful as a man » (678). In essence, Thoreau believes that a man who toils at any ruling institutions bidding simply because it bid him to do so sacrifices his own facilities as a human being. He then becomes nothing more than a man put  «on a level with wood and earth and stones Command[ing] no more respect than men of straw, or a lump of dirt » (678). Another quotation that helps to explicate Thoreaus Civil Disobedience is  «To be awake is to be alive. I have never yet met a man who was quite awake. In this phrase, Thoreau uses the term  «awake » as an euphemism for being fully aware of ones concept of right and fully in control of ones moral and physical existence. Understandably, people who are consistently awake, in this sense of the word, are hard to find:  «There are ine hundred and ninety-nine patrons of virtue to one virtuous man » (680). Also, the fact that Thoreau has  «never met a man who was quite awake » implies that fully conscious individuals have difficulty existing in modern society. In fact, Thoreau believes that  «no man with a genius for legislation has appeared in America. They are rare in the history of the world » (692). Perhaps, by the word  «awake, » and its equation with  «alive, » Thoreau is also referring to the ability to fulfill his own mission:  «I came into this world, not chiefly to make this a good place to live in, but to live in it, be it good or bad » (683). Although this concept is not a particularly unique one, it is nearly impossible to fulfill completelybut to fulfill it partially is useless. As a living being, one must  «cast your whole vote, not a strip of paper merely, but your whole influence » (684). To truly be alive, one must be consciously satisfied with every passing moment. Through his conscientious support of every facet of his philosophy, Thoreau effectively proves his statements regarding citizenship and government. He remains consistent to nearly every idea he presents and therefore surrounds them with a seriousness that cannot be ignored.
