The Role of the Nephron

The Roles of the Nephron of the 120 ml of blood that is filtered by the kidneys each minute, only I ml (that's less than I%) turns into urine that will eventually leave the body (after approximately 300 – 400 mis of it accumulates to fill the bladder! ) That leaves 119 ml of fluid called filtrate to be returned back to the blood stream. Good thing, otherwise you would have to micturate (pee, urinate) once every 3 minutes and drink 1 L of fluid every 10 minutes in order to maintain Homeostasis!!!The one million nephrons in each human kidney are amazingly efficient at selectively removing wastes from the blood while at the same time conserving water, salt ions, glucose and other needed materials. The nephrons accomplish this task in 3 main steps; these 3 steps are also called the 3 main roles of the nephron: Filtration, Reabsorption and Secretion. Fiftratffln Filtration is aecomplished by the movement of fluids from the blood into the Bowman's capsule. Beabsorpttort Reatuorptias wolves the selective transfer of essential solutes and water back into the blood.Secretion Secretion Involves the movement of wastes from the blood into the mphron. 1. Filtration The renal artery carries blood into the kidney (approximately 600 mis of blood enters a kidney each minute). The renal artery then branches into arterioles which then branch intoaspecialized capillaries called the glomerulus. Because of the great difference in diameter between the renal artery and the glomerul us, blood entering the glomerulus is under very high pressure. This pressure forces about 20% of the blood plasma (about 120m1 of the 600 ml) out of the glomerulus and across the membrane of Bowman's capsule.Bowman's capsule acts to â€Å"filter† or separate some of the substances that are located in blood plasma from others. This is because some substances are small enough to fit through the pores of the membrane of Bowman's capsule and some are too large and thus do not enter Bowman's capsul e with the rest of the blood plasma. Water, salt ions (sodium, potassium and choride), glucose molecules, amino acids and urea molecules are all small enough to go through the membrane pores into Bowman's capsule. Blood cells (rbc, wbc and platelets) and proteins on the other hand are too large to leave the capillaries or enter Bowman's capsule.The fluid inside of Bowman's capsule gets a name change; it is now called â€Å"filtrate† because it is blood plasma that has been filtered, This filtrate is identical to blood plasma minus the blood cells and proteins. Filtrate is said to be isotonic to blood plasma with respect to its concentration of water, salt ions, glucose, amino acids and urea. The filtrate will then proceed from Bowman's capsule through the rest of the nephron in the following order: proximal convoluted tubule, loop of henle, distal convoluted tubule and finally the collecting tubule.From the collecting tubule, the filtrate will enter the pelvis of the kidney a nd be called urine. 2. Reabsorption Useful materials such as sugars and salt ions are reabsorbed back into the blood stream. That is, materials that could still be used by the body are sent back to the blood. Reabsorption happens as filtrate passes sequentially through the nephron. Materials re-entering the blood stream do so through the capillary network surrounding the nephrons. In short, â€Å"good† stuff is sent from the nephron back into the blood. A.Proximal Convoluted Tubule (PCn: As the filtrate enters the PCT approximately 80% of the salt ions (sodium and potassium), glucose and amino acids are ACTIVELY TRANSPORTED out of the PCT and back into the blood stream by special â€Å"pumping† cells located in the walls of the PCT. The process of active transport requires energy. Energy in the form of ATP is supplied by the numerous mitochondria that are embedded in the walls of the PCT. Because of ionic attraction, negatively charged chloride ions (CI-) will flow pas sively out of the PCT as they are attracted by the positively charged sodium and potassium ions (Na+, K+).As the concentration of the above mentioned solute molecules drops inside of the PCT, water then diffuses out of the PCT and into the capillary network passively by the process of OSMOSIS. The lining of the PCT contains microvilli to increase the surface area over which this reabsorption can occur. B. Descending Loop of Henle: As the filtrate travels into the descending Loop of Henle, both sodium and potassium ions passively diffuse from the salty tissues of the surrounding medulla BACK INTO the Loop of Henle. (Although this is eabsorption of materials, the materials are not going back into the blood stream at this point). At the same time, water continues to move out of the Loop of Henle and into the capillary network by osmosis. The filtrate at this point is more concentrated (hypertonic) with respect to salt ions than it was in the PCT, both because water has been removed fro m it, and because salt ions have been again added to it. C. AscendineLoop of Henle As the filtrate proceeds up into the ascending Loop of Henle, the choride ions are actively pumped back out of the nephron.Because of ionic attraction, sodium ions then passively follow the chloride ions out of the tubule and into the tissues of the medulla. These ions only move into the medulla and not back into the blood stream. Since the ascending Loop of Henle is impermeable to water, water cannot leave this part of the nephron. Because of this, the filtrate gets more dilute again. Because the opposite happens in the ascending and descending Loops of Henle, the process is called the COUNTER CURRENT MECHANISM. The process is also known as the CHLORIDE SfUFT.D. Distal Convoluted Tubule (DCT) As the filtrate passes through this part of the nephron, water continues to passively diffuse out of the nephron and back into the blood. Water continues to diffuse out of the DCT because the surrounding tissues of the medulla are now very salty due to so much sodium and chloride ions accumulating there. The salty tissues attract the water out of the DCT because the medulla is hypertonic with respect to salt concentration when compared with the salt concentration of the filtrate (now hypotonic).Water that enters the medulla will then diffuse back into the blood stream. Because of the continual re-absorption of water, the filtrate becomes more and more concentrated with wastes, mainly urea. The amount of water that diffuses can be regulated by a hormone called ADH. The amount of water that diffuses from the DCT back into the blood depends on the needs of the body; if the body is dehydrated, more water will go back into the blood, and less will be left in the nephron to make less urine.The opposite occurs if the body is over hydrated. E. Collectin g Tubule C The same thing that occurs in the DCT also occurs in the CT 3. Secretion Occurring at the same time as reabsorption is a process called secretion. Secretion is when a cell releases a substance to its outside†¦ in this case, non-useful and toxic substances are ACTIVELY TRANSPORTED from the blood into the nephron – usually in the regions of the distal and proximal convoluted tubules.Substances which are secreted include excess acid (H+) or base (OH-) ions, excess glucose (high glucose levels are found in diabetic urine or urine of someone who has recently consumed a large amount of sugar-this is the kidney's way of helping to ensure that the blood sugar level doesn't get too high), ammonia, and drugs (this is why urine is used from many drug tests – the breakdown of many drugs including marijuana, cocaine, heroin, sleeping pills, codeine and many other medications can be detected even in minute amounts in the urine).The process of secretion ensures that materials that are potentially harmful to the body are quickly disposed of by being â€Å"dumped† into the fluid that is about to become uri ne. Secretion happens mainly in the regions of the DCT and CT but some also occurs in the PCT. In short, secretion involves â€Å"bad† stuff being removed from the blood being sent to the urine. of the loop after chlorine. The sodium rushes The Counter Current Mechanism of the Nephron out by diffusion because of its ‘fatal attraction' to chlorine.The chlorine and the sodium ions collect and dominate the fluids outside the loop The loop of Henle works toward the goal of water conservation. Animals that live in a terrestrial environment need to be careful not to waste water. It is clearly a waste,if water is in short supply, to release too much water with the urine. As a result there needs to be a mechanism to encourage water out of the urine and back into the blood. The loop of Henle creates that animals.There i s no way of actively capturing water in the urine that is passing through the collecting ducts. It would almost seem too late to capture the water that is alread y on its way out of the body. However, the nifty nephron creates a trick with its loop of lienle to get the water out of the collecting duct before it leaves the kidney, kidney. The ascending loop of Henle actively transports chlorine ions out of the filtrate with carrier proteins. Chlorine builds up in the fluids of the medulla by active transport.Because it is a negative ion, it creates a cause for the sodium ion, which is positive, to rush out It does so by creating a salty environment in the medulla area of the mechanism in terrestrial of I-fenle creating a salty environment.

The lottery

The Lottery Research Paper Shirley Jackson was a devoted mother and writer. Jackson didn't fit in well in North Bennington, and the town likely served as the setting for the New England town portrayed in â€Å"The Lottery. † â€Å"The Lottery' caused outrage and controversy when it appeared in the New Yorker in 1948, but many critics now consider it to be Jackson's most famous work. Jackson was sometimes thought to be a witch because of her interested in witchcraft and black magic. Almost all of Jackson's work is reflects horror, hauntings, witchcraft, or psychological unease.She also struggled with both mental and physical illnesses as an adult. Unlike other writers, she found the writing process pleasurable. â€Å"The Lottery' starts off in a town on a normal day with children going around and collecting rocks. The men of the households are called forward to a wooden box to draw slips of paper. When one of the men sees that he has the black dot on his slip, his wife immedi ately starts to argue with how the drawing wasn't fair. The family is brought to the stage where they are to draw their slips of paper. Tess (Mrs.Hutchinson) draws the paper with the black dot and is taken to the center of the town where the town's people take their stones that the children collected earlier hat day. As the villagers close in to primarily take Tess's life, all you can hear are her terrified shrilling screams. Shirley Jackson in her work â€Å"The Lottery' reveals the corrosive factors that result in our blind acceptance of morally questionable traditions that cause social paralysis. â€Å"The Lottery' starts off as a normal day in the village â€Å"it was clear and sunny with the fresh warmth of a full-summer day' Oackson 1).This is ironic because it starts off with this allusion of an enjoyable day but really by the end they end up killing one of their own villagers. Jackson does this to create a less serious atmosphere and reflect he attitudes of the community. Instantly, the boys are collecting rocks used to kill the lottery winner at the end of the story. This is an annual thing that the kids do because they have been raised and taught to do so. Because the kids are gradually and systematically exposed to these series of provoking objects and situations, they have become familiar with their actions making it an annual â€Å"game† for the kids (Linz 1).It has become a â€Å"game† for the kids because in the story it states that, â€Å"they gather together quietly for a while before they broke out into boisterous play' and that they find the smoothest and roundest rocks to stuff in their pockets. † Because the kids are repeatedly exposed to this violence it diminishes the negative affect that was once upon them. They can no longer see it as wrong or feel remorse. They blindly accept this task thats given to them every year and don't question it. The constant exposure to violence results in less physiological reactivit y to other violent actions going on around them (Linz 1).The killing of the villagers is the violence going on. Collecting stones has become a ritual that they believe is right, because it is what they have been raised to do, even though it is wrong. They are Just kids and haven't been taught that it is morally wrong to be killing friends and family. An example is at the end of the story when Mrs. Hutchinson's son was handed a few pebbles to throw at his own mother and didn't hesitate. When they are repeatedly exposed to violence 2). â€Å"Both beamed and laughed Oackson 6). This shows how they still find Joy in the situation even though they are about to kill a member of their family. The story goes on to talk about the families that are attending this so called lottery. The women are described as â€Å"housewives that gossip† Oackson 1) and aren't as authoritative as the men. While the boys are all collecting the stones, the women are â€Å"standing aside talking among th emselves. † In the story â€Å"the women began to call their children, and the children came reluctantly, having called four or five times. † When their father calls to them â€Å"they came quickly' Oackson 1).It is as if their mothers hadn't even said anything. This shows how the men are portrayed as the head of the house and they women more as Just the â€Å"housekeeper. † Their voices are not heard in this part of the story and neither at the end when Mrs. Hutchinson claims that, â€Å"It wasn't fair† and no one does anything about it but continues with the est of the lottery. Women have been known to rarely work outside the house and live their lives caring for their husbands and children while taking care of their home. Most males are prevailed as the dominant gender.The women are seen on a lower status (Gender Prejudice 1). The lottery seems to be run mostly by the men of the town. They are the ones that are in charge of the black box and most of th e ceremony. In the story the women are more resistant to the lottery while the men are the ones in control of it. This results in social paralysis of the town because no one wants to change how the lottery is run or who it's run by. When its time for the drawing, Mr. Dunbar is unable to draw so because he and his wife don't have kids the â€Å"Wife draws for the husband† Oackson 3).This all goes back to the role of the men and women in the village. The women are to produce many children so that it gives their family a better chance of surviving if their spouse is chosen in the first round (Oehlschlaeger 1). Men are the ones that go out and prevail in the business world while their wives stay home all day. When Mrs. Hutchinson arrives late she makes the statement that she â€Å"Thought my old man was out back stacking wood† and that she Wouldn't have me leave m'dishes in the sink Oackson 2),† implying that her husband was doing the hard labor out in the yard while she was inside doing dishes.They mention that most of the ritual has been forgotten over the years. â€Å"The original paraphernalia for the lottery had been lost long ago Oackson 1). It has become a habit that no one wants to stop. The lottery has become a social paralysis over time, not allowing anyone to step up and want to change or stop what the lottery is doing to their village. No one questions why they still do it and no one even really knows why they do it in the first place. It has lost its significance over the years and become a yearly act that no one has tried to stop.They don't want to make a new box because â€Å"No one wanted to upset even as much tradition as was represented by the black box Oackson 1). Tradition is a belief that has been passes down from generations, Just like in â€Å"The Lottery. † Traditions are passes on to gain that sense of continuity and bonding through each other. They are supposed to create that special connection between the fam ilies and in this case the town. That's not what it does though, No one knows the significants of the lottery anymore and no one questions ither. Old Man Warner says, â€Å"Pack of crazy fools† to the people that want to give up the lottery.They think that breaking this time-honored tradition would result in them (Tradition 1), such as drawing the paper from the box and having the men draw first then the family. Even though â€Å"So much of the ritual had been forgotten or discarded Oackson 2),† they still keep that cultural sense to it. The reverence regularly provided in tradition indicates that people follow it willingly even if they don't know why. â€Å"The people had done it so many times that they only half listened to the directions. † People follow tradition unconsciously because it's what they are taught to do.This is their blind acceptance of the lottery and social paralysis of not wanting to change what they have continued to do for numerous years. T raditions are invoked to preserve the sanctity of the past family rituals. Societies keep traditions for social connectedness and memories (Tradition 3). Throughout the story, â€Å"The Lottery,† Shirley Jackson uses harsh examples of how the village blindly accepts their morally questionable traditions resulting in social paralysis. They don't want to change anything about the lottery even though most of he significance has been lost over the years.There is evidence throughout the story that shows how the people blindly accept what they are doing to their town and do it without question. This all demonstrates how society never changes or grows resulting in the social paralysis of the story. Their is social paralysis going on all around the world. Even in Pakistan there are people refusing to act upon the issue of suicide happening at large rates ( Poverty and Social Paralysis. ) The lottery is Just an example of how some societies refuse to change even though what they are d oing needs to or should be stopped. The Lottery Lisa Marie Shade Prof. Dunn ENG 102-110 August 9, 2012 The Plot Thickens- In Shirley Jackson’s â€Å"The Lottery†. A good harvest has always been vital to civilizations. After the fields have been prepared and the seeds sown, the farmer can only wait and hope that the proper balance of rain and sun will ensure a good harvest. From this hope springs ritual. Many ancient cultures believed that growing crops represented the life cycle, beginning with what one associates with the end–death. Seeds buried, apparently without hope of germination, represent death.But with the life forces of water and the sun, the seed grows, representing rebirth. Consequently, ancient peoples began sacrificial rituals to emulate this resurrection cycle. What began as a vegetation ritual developed into a cathartic cleansing of an entire tribe or village. By transferring one's sins to persons or animals and then sacrificing them, people believed that their sins would be eliminated, a proce ss that has been termed the â€Å"scapegoat† archetype. In her short story â€Å"The Lottery,† Shirley Jackson uses this archetype to build on man's inherent need for such ritual.To visit upon the scapegoat the cruelties, that most of us seem to have dammed up within us and explores â€Å"the general psychological basis for such cruelty, showing how we tend to ignore misfortunes unless we ourselves are their victims. The Lottery’s [sic. ] then, deals indeed with live issues and with issues relevant to our time. Jackson's realism makes the final terror and shock more effective and also reinforces our sense of the awful doubleness of the human spirit—a doubleness that expresses itself in the blended good neighborliness and cruelty of the community's action. Evans, 112) Jackson weaves seasonal and life-death cycle archetypes, which coincide with vegetation rituals, into the story. The lottery takes place every year when the nature cycle peaks in midsummer, a time usually associated with cheerfulness. The villagers of a small town gather together in the square on June 27, a beautiful day, for the town lottery. In other towns, the lottery takes longer, but there are only 300 people in this village, so the lottery takes only two hours. Village children, who have just finished school for the summer, run around collecting stones.They put the stones in their pockets and make a pile in the square. Men gather next, followed by the women. Parents call their children over, and families stand together. Mr. Summers, a jovial man, who conducts the lottery ceremony, sets the tone of the event with both his name and his mannerisms. But lurking behind him, Mr. Graves quietly assists, his name hinting at a dark undertone. The picnic type atmosphere betrays the serious consequence of the lottery, for like the seed, a sacrificial person must also be buried to bring forth life. Jackson creates balance by assembling Mr.Summers and Mr. Graves to share in t he responsibilities of the ritual: Life brings death, and death recycles life. At one point in the village's history, the lottery represented a grave experience, and all who participated understood the profound meaning of the tradition. But as time passed, the villagers began to take the ritual lightly. They endure it almost as automatons–â€Å"actors† anxious to return to their mundane, workaday lives. Old Man Warner, the only one who seems to recall the seriousness of the occasion, complains that Mr. Summers jokes with everybody.But, even if one does not understand the meaning, the experience provides the individual a place and a meaning in the life of the generations. Because there has â€Å"always been a lottery† (Jackson 216), the villagers feel compelled to continue this horrifying tradition. They do focus, however, on its gruesome rather than its symbolic nature for they still remembered to use stones even after they have forgotten the ritual and lost the original black box (Jackson 218). The reader may conclude that humanity's inclination toward violence overshadows society's need for civilized traditions. Mr.Summers asks whether anyone is absent, and the crowd responds that Dunbar isn’t there. Mr. Summers asks who will draw for Dunbar, and Mrs. Dunbar says she will because she doesn’t have a son who’s old enough to do it for her. Mr. Summers asks whether the Watson boy will draw, and he answers that he will. Mr. Summers then asks to make sure that Old Man Warner is there too. Mr. Summers reminds everyone about the lottery’s rules: he’ll read names, and the family heads come up and draw a slip of paper. No one should look at the paper until everyone has drawn. He calls all the names, greeting each person as they come up to draw a paper.Mr. Adams tells Old Man Warner that people in the north village might stop the lottery; he says that giving up the lottery could lead to a return to living in caves . Mrs. Adams says the lottery has already been given up in other villages, and Old Man Warner says that’s â€Å"nothing but trouble. † (Jackson, 216). The shock value of the long process and all the moments’ one character or another could have realized the nonsense of the ritual and spoke up. When Mr. Summers finishes calling names, and everyone opens his or her papers. Word quickly gets around that Bill Hutchinson has â€Å"got it. Tessie argues that it wasn’t fair because Bill didn’t have enough time to select a paper.Mr. Summers asks whether there are any other households in the Hutchinson family, and Bill says no, because his married daughter draws with her husband’s family. Mr. Summers asks how many kids Bill has, and he answers that he has three. Tess's eagerness to see the lottery through is only paralleled by her desperation to get out of it once it turns out to be her turn. She goes so far as to try to substitute her daughter and s on-in-law for herself, yelling, â€Å"There's Don and Eva†¦ Make them take their chance! Her extreme moral compromise, as she tries to offer up her daughter for the slaughter instead of herself, underlines that this ritual has nothing to do with virtuous martyrdom; Tess is no saint. Her murder is exactly that: a vicious, group killing of a frightened, antiheroic woman. Tessie protests again that the lottery wasn’t fair. Mr. Graves dumps the papers out of the box onto the ground and then puts five papers in for the Hutchinsons. As Mr. Summers calls their names, each member of the family comes up and draws a paper. When they open their slips, they find that Tessie has drawn the paper with the black dot on it.Mr. Summers instructs everyone to hurry up. The villagers grab stones and run toward Tessie, who stands in a clearing in the middle of the crowd. Tessie says it’s not fair and is hit in the head with a stone. Everyone begins throwing stones at her, as even her own children. â€Å"Tessie may be selfish in her reaction, but her claim that the lottery is not fair may still be true. Whereas the common villagers are described as â€Å"taking† their slips, the businessmen â€Å"select† theirs—a subtle implication that the results have been rigged† (Evans, 112-113) Therefore, the base actions exhibited in groups (such as the stoning of Mrs.Hutchinson) do not take place on the individual level, for here such action would be deemed â€Å"murder. † On the group level people classify their heinous act simply as â€Å"ritual. † When Mrs. Hutchinson arrives at the ceremony late, flustered because she had forgotten that today was the day of the lottery. She chats sociably with Mrs. Delacroix. Nevertheless, after Mrs. Hutchinson falls victim to the lottery selection, Mrs. Delacroix chooses a â€Å"stone so large† that she must pick it up with both hands (Jackson 218).Whereas, on the individual level, the two women regard each other as friends, on the group level, they betray that relationship, satiating the mob mentality. The people of the town are caught up in the ritual to such an extent that they have given up any sense of logic. Mob psychology rules their actions. Though they appear to be sane, sensible individuals, when the time of the lottery comes, they abandon their rational nature and revert to the instincts of the herd. This psychological phenomenon is characteristic of humans throughout history.Although Jackson portrays it in its extreme form in this story, the idea that men and women in groups are willing to forgo personal responsibility and act with great cruelty toward others is evidenced in actions such as lynch mobs, racial confrontations, and similar incidents. â€Å"The willingness of people to act irrationally as members of the herd displays aspects that, while unpleasant, are still integral parts of their nature that they must recognize, if they are to keep them in check. † (Mazzeno) A first-time reader of â€Å"The Lottery† often finds the ending a surprise.The festive nature of the gathering and the camaraderie of the townspeople as the lottery is conducted belie the horror that occurs at the conclusion of the tale, is one of the tale’s strongest points. Another strength, however, is â€Å"the skillful way in which Jackson prepares the careful reader for the denouement by including key details so that, on a second reading, one is assured that there is no trick being played on the reader. † (Mazzeno) In comparison to the heavily symbolic figures of Mr. Graves (Death), Mr. Summers (Progress), or Old Man Warner (Tradition), Tess is resolutely anti-symbolic.She's a woman in an apron with soapsuds on her hands, who cracks jokes and wants to join in her community – but, it turns out, they don't want her back. She's the sacrificial lamb for that year, an outsider that the village then violently excludes. Althou gh civilized people may no longer hold lotteries, Jackson's story illustrates that society's tendency toward violence and its tendency to hold onto tradition, yet even meaningless, base tradition, reveal our need for both ritual and belonging.Work Cited Evans, Robert C. â€Å"The Lottery. † Short Fiction: A Critical Companion (1997): 112-119.

Mr. Summers asks whether the Watson boy will draw, and he answers that he will. Mr. Summers then asks to make sure that Old Man Warner is there too. Mr. Summers reminds everyone about the lottery’s rules: he’ll read names, and the family heads come up and draw a slip of paper. No one should look at the paper until everyone has drawn. He calls all the names, greeting each person as they come up to draw a paper.Mr. Adams tells Old Man Warner that people in the north village might stop the lottery; he says that giving up the lottery could lead to a return to living in caves . Mrs. Adams says the lottery has already been given up in other villages, and Old Man Warner says that’s â€Å"nothing but trouble. † (Jackson, 216). The shock value of the long process and all the moments’ one character or another could have realized the nonsense of the ritual and spoke up. When Mr. Summers finishes calling names, and everyone opens his or her papers. Word quickly gets around that Bill Hutchinson has â€Å"got it. Tessie argues that it wasn’t fair because Bill didn’t have enough time to select a paper.Mr. Summers asks whether there are any other households in the Hutchinson family, and Bill says no, because his married daughter draws with her husband’s family. Mr. Summers asks how many kids Bill has, and he answers that he has three. Tess's eagerness to see the lottery through is only paralleled by her desperation to get out of it once it turns out to be her turn. She goes so far as to try to substitute her daughter and s on-in-law for herself, yelling, â€Å"There's Don and Eva†¦ Make them take their chance! Her extreme moral compromise, as she tries to offer up her daughter for the slaughter instead of herself, underlines that this ritual has nothing to do with virtuous martyrdom; Tess is no saint. Her murder is exactly that: a vicious, group killing of a frightened, antiheroic woman. Tessie protests again that the lottery wasn’t fair. Mr. Graves dumps the papers out of the box onto the ground and then puts five papers in for the Hutchinsons. As Mr. Summers calls their names, each member of the family comes up and draws a paper. When they open their slips, they find that Tessie has drawn the paper with the black dot on it.Mr. Summers instructs everyone to hurry up. The villagers grab stones and run toward Tessie, who stands in a clearing in the middle of the crowd. Tessie says it’s not fair and is hit in the head with a stone. Everyone begins throwing stones at her, as even her own children. â€Å"Tessie may be selfish in her reaction, but her claim that the lottery is not fair may still be true. Whereas the common villagers are described as â€Å"taking† their slips, the businessmen â€Å"select† theirs—a subtle implication that the results have been rigged† (Evans, 112-113) Therefore, the base actions exhibited in groups (such as the stoning of Mrs.Hutchinson) do not take place on the individual level, for here such action would be deemed â€Å"murder. † On the group level people classify their heinous act simply as â€Å"ritual. † When Mrs. Hutchinson arrives at the ceremony late, flustered because she had forgotten that today was the day of the lottery. She chats sociably with Mrs. Delacroix. Nevertheless, after Mrs. Hutchinson falls victim to the lottery selection, Mrs. Delacroix chooses a â€Å"stone so large† that she must pick it up with both hands (Jackson 218).Whereas, on the individual level, the two women regard each other as friends, on the group level, they betray that relationship, satiating the mob mentality. The people of the town are caught up in the ritual to such an extent that they have given up any sense of logic. Mob psychology rules their actions. Though they appear to be sane, sensible individuals, when the time of the lottery comes, they abandon their rational nature and revert to the instincts of the herd. This psychological phenomenon is characteristic of humans throughout history.Although Jackson portrays it in its extreme form in this story, the idea that men and women in groups are willing to forgo personal responsibility and act with great cruelty toward others is evidenced in actions such as lynch mobs, racial confrontations, and similar incidents. â€Å"The willingness of people to act irrationally as members of the herd displays aspects that, while unpleasant, are still integral parts of their nature that they must recognize, if they are to keep them in check. † (Mazzeno) A first-time reader of â€Å"The Lottery† often finds the ending a surprise.The festive nature of the gathering and the camaraderie of the townspeople as the lottery is conducted belie the horror that occurs at the conclusion of the tale, is one of the tale’s strongest points. Another strength, however, is â€Å"the skillful way in which Jackson prepares the careful reader for the denouement by including key details so that, on a second reading, one is assured that there is no trick being played on the reader. † (Mazzeno) In comparison to the heavily symbolic figures of Mr. Graves (Death), Mr. Summers (Progress), or Old Man Warner (Tradition), Tess is resolutely anti-symbolic.She's a woman in an apron with soapsuds on her hands, who cracks jokes and wants to join in her community – but, it turns out, they don't want her back. She's the sacrificial lamb for that year, an outsider that the village then violently excludes. Althou gh civilized people may no longer hold lotteries, Jackson's story illustrates that society's tendency toward violence and its tendency to hold onto tradition, yet even meaningless, base tradition, reveal our need for both ritual and belonging.Work Cited Evans, Robert C. â€Å"The Lottery. † Short Fiction: A Critical Companion (1997): 112-119.

Jackson was sometimes thought to be a witch because of her interested in witchcraft and black magic. Almost all of Jackson's work is reflects horror, hauntings, witchcraft, or psychological unease.She also struggled with both mental and physical illnesses as an adult. Unlike other writers, she found the writing process pleasurable. â€Å"The Lottery' starts off in a town on a normal day with children going around and collecting rocks. The men of the households are called forward to a wooden box to draw slips of paper. When one of the men sees that he has the black dot on his slip, his wife immedi ately starts to argue with how the drawing wasn't fair. The family is brought to the stage where they are to draw their slips of paper. Tess (Mrs.Hutchinson) draws the paper with the black dot and is taken to the center of the town where the town's people take their stones that the children collected earlier hat day. As the villagers close in to primarily take Tess's life, all you can hear are her terrified shrilling screams. Shirley Jackson in her work â€Å"The Lottery' reveals the corrosive factors that result in our blind acceptance of morally questionable traditions that cause social paralysis. â€Å"The Lottery' starts off as a normal day in the village â€Å"it was clear and sunny with the fresh warmth of a full-summer day' Oackson 1).This is ironic because it starts off with this allusion of an enjoyable day but really by the end they end up killing one of their own villagers. Jackson does this to create a less serious atmosphere and reflect he attitudes of the community. Instantly, the boys are collecting rocks used to kill the lottery winner at the end of the story. This is an annual thing that the kids do because they have been raised and taught to do so. Because the kids are gradually and systematically exposed to these series of provoking objects and situations, they have become familiar with their actions making it an annual â€Å"game† for the kids (Linz 1).It has become a â€Å"game† for the kids because in the story it states that, â€Å"they gather together quietly for a while before they broke out into boisterous play' and that they find the smoothest and roundest rocks to stuff in their pockets. † Because the kids are repeatedly exposed to this violence it diminishes the negative affect that was once upon them.

The constant exposure to violence results in less physiological reactivit y to other violent actions going on around them (Linz 1).The killing of the villagers is the violence going on. Collecting stones has become a ritual that they believe is right, because it is what they have been raised to do, even though it is wrong.

Asian people taking on non-typical or roles they are not characterized to in British cinema - Essay Example And that is what is the Asian Artists in England are aiming for; to craft their story and the performance in such a way that it entertains and touches the heart of the English community as much as it does of the Asian people. Asian directors are doing their best to bid for the mainstream. The year was 1986. A movie called ‘My beautiful Laundrette’ was released. Scripted by writer from Asian origin, Hanif Kureishi, the movie tells a story of the Asian community living in London [1]. It proved to be a commercially successful movie and gave inspiration to the upcoming Asian artists in England a hope to confidently launch their career move thinking that ‘mainstream’ is not out of their reach ((Korte and Sternber ,2004. pg. 49). help of his school friend Johnny, turns around the business of laundry.

Management Accounting Techniques and decisions - Essay Example The aspect of erasing the salary part improves the wholesome performance of the managers with the development of workplace initiatives, team work, adaptability, compliance to business policies thereby resulting in increase of the production and the service levels of the organization. The incentives are often linked in the right way to the performance measures with appropriate weight-ages to the several benchmarks of performance measurement (Marr and  Gray, 2012, p.68). The manager’s ability to meet the benchmark standards determine the rewards and the compensation that are received by them. The higher the achievements of the manager in comparison to the benchmark standards, the higher the rewards the managers should be eligible to receive. The benchmarks are set in the various areas of operation of the organization in order to fulfil its organizational objectives. These areas which include benchmark standards of performance of the employees are aimed at fulfilling the financ ial goals of the company, the customer service, the standards of the internal processes and the learning goals of the organization (Tonchia and  Quagini, 2010, p.78). The financial benchmarks of the manager’s performance indicates the desired output from the managers that would contribute to the attainment of certain production volumes in line with the quality standards to be maintained for the products. Thus the benchmarks help in assessing the extent to which the manager has been able to contribute to the production volumes of the company and at the same time maintained the quality of production (Niven, 2010, p.34). The use of benchmarks in measuring the performance helps to identify the short cut approaches adopted by the employees which is aimed at fulfilling the short term goals but do not fulfil the organizational objectives. The benchmark system helps to understand whether the performance of the managers has been up to the mark in all aspects of the manager’s performance, like in this case both product quantity as well as quality. The benchmarks set in the area of customer service is also important to measure the performance of the managers as this is also an important area considered for the sustainability of the business of the organizations. The various benchmarks in the area of performance measures for customer service includes the turn-around time to the customers, the number of complaints that have been lodged by the customers, the time taken for the resolution of complaints by the manager. These benchmarks help to measure the extent to which the manager has been able to respond to the customer requests which is determined the turnaround time. The compromise of any one of the performance measures may lead to complaints from the customer. The benchmarks determine the rate at which complaints have been filed against the work of the managers and thus indicate the gaps with the benchmark standards of performance. The benchmark system a lso provides an insight on the effectives of the manager in resolution of customer complaints. The inputs received from the

Transplant - Coursework Example The disadvantage is that it causes people to think about donating organs without inherently wanting so. Also, ‘Youre also giving up your right to informed consent. Doctors dont have to tell you or your relatives what they will do to your body during an organ harvest operation because youll be dead, with no legal rights† (Teresi, 2012). The main factor that causes this discrepancy is the unwillingness to donate the organ in the relatives. Each year, at least 5000 medically transplantable organs are refused donation by the relatives in the US (Reeves et al., 2004). Other factors may include diseased or infections organs in the donors, and religious and cultural stance on donation. A professional nurse plays a very important role of advocate and educator in organ donation. Professional nurses facilitate organ donation process by convincing the donors and their relatives of the safety of operation. Their role as psychological counselors of the donors and their relatives is also very

Analysis of Heart of Darkness Essay Example | Topics and Well Written Essays - 1000 words

Analysis of Heart of Darkness - Essay Example Referred to as the â€Å"dark continent†, Africa was one of the world’s ‘dark places’ that the Europeans had colonized by the 1890s. It is perceived in other the places (Africa, England and Brussels) that Conrad describes as depressing, dark areas. Darkness symbolizes the unknown, gaining power because we are afraid to find out what it is hiding from us (for example, in Section 2, Part II, when Marlow’s steamer enters an oppressive fog bank resulting in blurring and distortion of vision, the men aboard it are terrified when they hear a high-pitched scream followed by a clamor of savage voices; their terror emanates from their knowledge that danger is lurking somewhere in the foggy darkness, but they are unable to see it or gauge its potency (http://www.novelguide.com/heartofdarkness/index.html). It is the metaphoric meaning of darkness that is more prevalent throughout the novel. Conrad refers to darkness as the human inability to see beyond another individual’s personal faà §ade, and the inability to understand the feelings of that individual, both of which lead to inability to establish any sort of mutual understanding or sympathetic interaction with that person. Darkness is compelling and alluring. Unknown danger has always been a magnet that has drawn humans to dare and explore it. In the context of the novel, darkness conceals unknown dangers in Africa that Europeans dare to tackle for the rewards it would bring. To the company men, the reward is material wealth represented by ivory; to Marlow, the African darkness conceals adventure, this being the main reason he traveled to that place due to a map he came across (Section 1, Part I), depicting the region as unexplored land (http://www.novelguide.com/heartofdarkness/index.html). Darkness is used as a cloak to conceal acts of savagery. Conrad suggests that such a cloak of darkness can camouflage savage acts that would be impossible to contemplate in European civilization. For example, Kurtz

Why is it difficult for parents and children to communicate Research Paper

Why is it difficult for parents and children to communicate - Research Paper Example Proper communication between parents and children also project that they hold individual value to the family, which in turn helps in developing their overall confidence level by a considerable level (New Mexico State University, n.d.). However, it becomes quite difficult for the parents to maintain a smooth communication with their children specifically during the adolescent stage. In this particular stage, the parents and the children experience much tension, which eventually results in deteriorating the parent-child relationship to a major extent (Swerdlow-Freed Psychology, P.C, 2014). With this concern, the prime intention of this research paper is to identify along with discuss about the various stress related factors that are faced by the children during their childhood stage, which results in improper parent-child communication. The various sorts of parent-child communication issues would be presented in this research paper with the aim of determining about why it often becomes quite difficult for parents and their children to communicate in an effective manner. Adolescent Stage Issues. As already discussed above, parent-child communication issues mostly occur during the adolescent stage of the children. During this stage, every child desires to be independent in terms of taking own decisions and act accordingly. In this stage, every child starts demanding for his/her own individuality within the family and friends circle, resulting in raising disturbances and tensions at large (Swerdlow-Freed Psychology, P.C, 2014). Thus, in this regard, it often becomes much difficult for parents and children to communicate. Ignorance from Parents. At certain times, it can be seen that the communication link between parents and children also get decimated due to the ignorance made by the parents towards the children. Majorly, it is observed that due to the lower level of family income, the parents of the children are forced to work outside. This eventually gives

Why does it matter what shape a molecule has Essay

Why does it matter what shape a molecule has - Essay Example These are the contexts in which the manner in which materials behave are described, whether they are simple gases, or complex biological structures. The bonds between atoms have distinct lengths, energy and direction which distinguish the atomic structure of materials. The shape of a molecule is formed by the spatial relationships of chemically bonded atoms, and this feature contributes significantly to understanding how molecules react with each other. Ionic bonds are formed by the electrostatic attraction between a cation and an anion. The electric field of an ion has spherical symmetry, hence ionic bonds have no directional character. Contrastingly, covalent bonds are formed by the overlap of atomic orbitals. Since the overlap is such that the atomic orbitals can attain maximum overlap, a covalent bond has a directional character. Therefore, â€Å"the shape of a molecule is determined by the angle between two bonds, which in turn is determined by the atomic orbitals that form the bond† (Iwanami 2006, p.1). Thesis Statement: The purpose of this paper is to investigate why the shape of a molecule is significant in the study of chemistry. ... The attraction between two adjacent non-polar molecules increases in proportion to the area of contact. Generally, the closeness of the tie between the two increases with greater area of van der Waal’s contact attraction and also with the degree of hydrogen bonding. The higher the level of molecular fit, the stronger is the affinity between a molecule and the biomolecular target in therapeutic agents. A therapeutic agent or medicine in aqueous solution is stablized by hydrogen bonding to water and dipolar solvation. It is evident that in medicines, there is a trade-off; they must be sufficiently well solvated to be soluble in water, â€Å"but not so strongly solvated that they cannot be pulled from solution by the target biomolecule† (Corey et al 2012, p.55). Noncyclic organic molecules are usually flexible because the barrier to rotation about single bonds having low energy. Therefore, most medicines’ structures have cyclic subunits with a few preferred conforma tions, sometimes just one. Fig.1a. and 1b. show the conformation of prednisone, a significant anti-inflammatory and immunosuppressive drug, along with the preferred conformation of glucose. Fig.1a. Chemical Structure of Glucose Molecule (Corey et al 2012, p.56) Fig.1b. Prednisone Chemical Structure (Corey et al 2012, p.56) While the molecular formula for glucose is C5H12O6, the formula for prednisone is C21H26O5. â€Å"The polycyclic framework of prednisone is quite rigid and gives the molecule a characteristic shape† (Corey et al 2012, p.56). Concurrently, several polar functional groups are situated at specific sites in space, facilitating their optimal binding to the target molecule. The Different Shapes of Molecules Based on Structure There are compounds with a divalent central

SUmmary for an - Article Example The author describes his own gradual discovery of life-threatening illness, and the implications of this for him on a personal level, and he sets this within the wider context of the human condition generally. The first major insight that the author reports is that he becomes obsessed, in a rather unpleasant way, with his own body and that it is not so much the physical symptoms of disease that affect him, as the psychological ones â€Å"its most profound effect was upon my consciousness, my self-awareness, the way I apprehended and constructed the world and my position in it† (p. 13). Murphy comments on the tendency of clinicians to diagnose psycho-somatic illness when they cannot identify any clear physical cause for the symptoms reported. There is an amusing account of a visit to a psychiatrist, whom the author dismisses with an academic remark about the proposed treatments, and an honest admission of the author’s limited understanding of the field of neurology. Throughout the article the author highlights the euphemistic use of language as a way of trying to reassure people in the face of unwelcome developments, for example â€Å"the unforgivable neologism restructuring† (p. 10) which really means financial cuts, and medical terms like â€Å"obstruction† (p. 17) which really means a tumor. This illustrates one of his main themes, which is the way that sub-groups in society using slanted definitions to pull unwary outsiders into their own mini-world in which power structures privilege the insiders. This insight relates to the theories of Talcott Parsons relating to the so called â€Å"sick role† and Goffman relating to front and back stage behavior, which explain how illness takes over the whole of a person’s life, robbing him or her of freedom and prescribing new rules and a new objective, namely to get well again. The institution imposes a new identity on the patient, and he has to adjust to its expectations. The article ends with some

Computer Game Addiction Essay Example for Free

Computer Game Addiction Essay ABSTRACT With the constant improvements in gaming technology, ranging from graphics to new types of controllers to faster processors, there is a growing problem of computer game addiction. In order to fully understand this problem, one must define addiction. According to the Center for Addiction and Mental Health, addiction is a psychological or a physical dependence on something. LITERATURE REVIEW In this paper, we will discuss the problem of computer game addiction, one of the most addictive games, and ways to prevent or stop addiction. Massively Multiplayer Online Role- Playing Games Game addiction really started turning into a problem with the advent of Massively Multiplayer Online Role- Playing Games, or MMORPGs. While regular games would keep you entertained until you beat it, MMORPGs have no ending, so there really is no reason to stop playing. MMORPGs immerse the player in the world and since there is no way to beat the game, the goal is character progression. Leveling up your character and obtaining better and better armor and weapons is usually the norm in most MMORPGs. Addiction Questionnaire Dr. Kimberly Young, known as â€Å"the world’s foremost Cyber-Psychologist,† created a set of eight questions to ask one’s self to test for online gaming addiction. 1) Do you need to play online games with increasing amounts of time in order to achieve the desired excitement? 2) Are you preoccupied with gaming (thinking about it when offline, anticipating your next online session)? 3) Have you lied to friends and family members to conceal extent of your online gaming? 4) Do you feel restless or irritable when attempting to cut down or stop online gaming? 5) Have you made repeated unsuccessful efforts to control, cut back, or stop online gaming? 6) Do you use gaming as a way of escaping from problems or relieve feelings of helplessness, guilt, anxiety, or depression? 7) Have you jeopardized or lost a significant relationship, or even risked your marriage because of your online gaming habit? 8) Have you jeopardized a job, educational, or career opportunity because of your online gaming habit? Answering yes to any of those questions could mean that you are addicted. One would think that video games are harmless, but once they start interfering with real life and even take precedence over it, then there is a real problem. Video game addiction has not received official recognition as a diagnosis in theDSM IV standard [8], but is still aconcern for many people. Problems with addiction One study done on the problems of addiction used a modified version of the formal definition of gambling addiction. 607 8th and 9th grade students where surveyed, and of these 15% where classified as addicted. Of the addicted students, approximately 80% where male. Less than 30% of non-addicted student reported having been in a fight in the past year, while almost 50% ofaddicted students reported the same. Addiction also correlated with reported arguments with friends, and with teachers. Just as many students classified as addicted reported having a B average as those classified as nonaddicted. However, there where 4 times as many F students classified as addictedas there where non-addicted, and far more non-addicted A students than addicted ones. Not surprisingly, students classified as addicted averaged almost 4 times as much playtime as nonaddicted ones [7]. These figures are somewhat worrying. World of Warcraft (WoW) The current king of MMORPGs is World of Warcraft. According to a press release on Blizzard’s World of Warcraft webpage, World of Warcraft’s subscriber base numbers more than 8.5 million, as of March 7, 2007, and it continues to grow every day. The expansion pack that was recently released sold nearly 2.4 million copies worldwide just on the first 24 hours [3]. It is often referred to as â€Å"World of Warcrack.† Dr. Maressa Orzak, a Harvard professor and founder of Computer Addiction Services at McLean Hospital in Newton, MA, estimates that as many as 40% of the people who play WoW are addicted. She believes that games like World of Warcraft are designed to keep people in the game and that they are inherently addictive [4]. There are dozens of websites just for the purpose of providing support for WoW addiction. The game has a feature where if you type â€Å"/played† into the chat interface, it displays how much time you have spent playing that particular character. Some people report that they’ve spent 200 to 300 days played in the game [5]. In 2004, Zhang Xiaoyi, a 13 year old Chinese boy, committed suicide by jumping off a building afterplaying World of Warcraft for 36 hours straight. He left a suicide note saying that he wanted to â€Å"join the heroes of the game he worshipped† [6]. Fig. 1: A large battle between the Alliance and the Horde Is it Addiction? According to Weimer-Hastings and Ng, many people who are excessive MMORPG users are not actually dependent on video games [8]. They propose that many of these people use video games not because they are addicted, but because it is the only comfortable social medium for them. This was found through a comparison ofMMORPG player and other video game players. The MMORPG players tended to spend far more time playing, but much of that time is spent socializing. Some MMORPG players who showed long hours of playtime didn’t actually show any of the signs of addiction [8]. This study shows that care must be taken with the definition of addiction. Conclusion Video game addiction is something we must come to terms with as a society. Whether it is decided to be a read full fledged addiction, or just a compulsive behavior, it can still cause trouble in peoples lives. The problem will not go away either, it will probably only get worse, as designers get a better understanding of what makes consumers want their games. On the other hand, the problem is not as bad as it sounds at first. For many people these games are a social outlet, not an addiction. Video games are an integral part of many peoples lives now, and theyre here to stay. Lets learn to use them responsibly. References 1.

Obamacare Essay Example for Free

Obamacare Essay â€Å"Change will not come if we wait for some other person or some other time. We are the ones weve been waiting for. We are the change that we seek.† Those words were famously spoken from Barack Obama during his election period. Following through with those words, he begins to make change in the country. Change isn’t easy, yet you hope it’s worth it in the end. The USA seems to be standing on both sides of the fence when it comes to the changes the President is making with healthcare. March 23, 2010 Obama signed into law Affordable Care Act, or better known as Obamacare. Together with the Health Care and Education Reconciliation Act, it represents the most significant government expansion and regulatory overhaul of the U.S. healthcare system since the passage of Medicare and Medicaid in 1965 (www.obamacarefacts.com). Obamacare was enacted to provide affordable health insurance to 44 million uninsured Americans and to reduce the growth in health care spending. Obamacare has done some important things already, such as prohibiting insurance companies from dropping your coverage if you get sick and has been working with insurance companies who will not cover a person because of a pre-existing condition. However, as with all change there are two ways at looking at the new bill. Obamacare will drastically affect the low-income families in a positive way. In America healthcare is so difficult to afford for the average low-income family, Obama has placed the care on a sliding scale. The expansion will cover over 15 million low-income individuals and families below the 133% FLP mark. However each state has the option to opt-out of providing coverage for the poor. By not providing coverage for the poor, it will leave 2-3 million people without coverage. States that decide to opt-in employers will have to respond by laying people off and making full time employees part time to avoid Obamacare penalties and taxes by not implementing the program. Others will not expand beyond 50 employees to avoid the bill’s mandate’s (Shenk, 2013). The average consumer will see a difference because some businesses are adding surcharges to invoices in to help make up the cost of healthcare coverage for their employees. On a positive note, there would be no annual or lifetime limits, children can stay on their parent’s plans to age 26; FDA can approve more generic drugs driving prices down and breaking monopolies and protections against discrimination for gender, disabilities and domestic abuse. And there will be significant tax credits to the small businesses with less than 25 employees, to help offset the costs of providing coverage to their employees. Obamacare will certainly challenge the nation over whether it wants a national system to be dependent on Washington or rely on dual federalism that protects freedom. The bill doesn’t allow the American citizen the option, if they want to offer or accept coverage; they have to have it or they will be penalized. That doesn’t allow much freedom of choice, however at least they are being offered the opportunity to coverage. Despite the rocky road Obamacare has had to start, it has lived to see another day and each day the kinks are worked out. This bill is here to stay. So, as cchange isn’t always easy, the average American citizen can say that the law will be beneficial to them as individuals, their families, communities, and country.

The Hotel Reservation System

The Hotel Reservation System Abstract The Riviera resort is a tourist resort. It is located in Greenwich, in the south east London of United Kingdom. This resort was established in 2000. This resort has 38 rooms with all the facilities. There are double, single and family rooms with attached bathrooms. There are indoor and outdoor games facilities with a swimming pool. Air-conditioned rooms too are available. Within a distance of a few yards the real maritime view is attractive for the tourist for enjoyment. As Hotel Riviera a customer based Company it is identified that providing an efficient customer service is a major factor that is considered in all customer based Companies, to remain competitive in the market. One major barrier to this is the manual system does not provide any facility for the Managers, Accountants and other employees to trace the routine details on time and provide a quality of service. Which ultimately lead to a lot of problems and inefficiencies? In the aim of solving these problems and making the company operate efficiently, the Hotel Reservation System with online Environment to Hotel Riviera System project was undertaken. In here this system was strengthen in web base access as well as with a Visual Basic component that was used to track the reservations done by the Employees each day. In this system the Administrators get the chance to view their routine details as well as the reservation details at the company. So the managers can get a good idea what sort of things they have to do in order to improve their business activities The benefits of the system are numerous. The system will help the company to operate efficiently by eliminating all the time consuming procedures and provide a better service to their Customers. Introduction Hotel Riviera Information The Riviera resort is a tourist resort. It is located in Greenwich, in the south east London of United Kingdom. This resort was established in 2000. This resort has 38 rooms with all the facilities. There are double, single and family rooms with attached bathrooms. There are indoor and outdoor games facilities with a swimming pool. Air-conditioned rooms too are available. Within a distance of a few yards the real maritime view is attractive for the tourist for enjoyment. To maintain the resort there are working thirty employees as Managers, Accountant, Supervisors, Cashier, Room boys, Servants, Cleaners, and Cookers. Everyday foreign and local guests visit and enjoy with the resort facilities. The resort owner is very happy about the success of his resort. Room Information 20- A/C and 18 Non A/C rooms. 12-Rooms with single bed facility A/C, 8 non A/C single bed rooms 10-Rooms are the double bed A/C and 8-double bed non A/C. Problem Identified Out of survey done by me, I found the numerous problems faced by the Owner and other employees of the company. The main drawback of their currently available system is that for many processes are very time consuming. So the company required a system that will produce out puts in on time. Also the time that takes to send services to customers are quite high. Next the company does not have an easy way to trace the reservation process. Introduction of the Current Information System The Resort is one of the famous resorts in United Kingdom which is currently doing everything in a manual way. Although if they have a number of computers even they dont have any computerized system. Their Guest and staff are facing lots of problems in their day today activities. So I proposed them to carry out their resort reservation system details in a computerized manner. These are the major functions/processes occurring which is manual way. Guest registration Room reservation Food order Payment calculations Functions of the Existing System Hotel has four departments: 1. Front office This department contains 2 employees: Receptionist and Front Office Manager. Main functions: 1. Request booking information 2. Confirm booking. 3. Cancel booking. 2. Kitchen department. This department contains 15 employees: Chief cook, Cooks, Supervisor, and Supplier for groceries Main functions: Prepare meals according to the guest preference. 2. Prepare food menu information. 3. Housekeeping department. This department contains 8 employees: House keeper, Record keeper Supervisor and Cleaners. Main function 1. Check the room availability information and pass to the front office. 2. Reservation of room. 4. Finance department. These departments contain 5 employees: Accountant, Manager, Finance Manager, Account operators Main Functions: 1. Calculate Guest payments. 2. Prepare invoices. 3. Salary functions. 4. Profit and loss analysis. Purposes and Objectives of This Project The proposed computerized system purposes and objectives are as follows. With the earlier system the customers had to idle till the receptionist filled all data. But, with the proposed system the customer related activities will be very quick and efficient. Less waste of resources, because only necessary data will be taken into Hard Copy out puts. In the manual system data duplication was happening frequently. But, with the proposed system data redundancy will be reduced to a great extent. Security measures will be introduced; therefore data is 99% accurate and reliable. The company can convert into new trends of technology and give a Better competition with its competitors. The company profitability can be increased because the cost that was incurred for maintaining the system will be cut down. Work load of the employee is lifted off. The proposed system requires only a computer therefore there is no need of large room space. There is no need of large storage cupboards because all data will be stored in one single database of the computer. The manual system did not have any back-up files, but with the computerized if any files have been missed up there is a back-up procedure to fix the problem. Issues of the Existing System The data is not long-lasting for this hotel due to the improper system:- The resort reservation System is maintaining their data and information in the files and some copies. So it is not secure for them. Not only that but it can destroy in a particular period. It can be misplaced somewhere. They have to buy the files and copies. So it is not proper system for them. It is time consuming :- Very important but this manual system is very slow and extremely time consuming. So that guest time also wasting. When more than one guest arrives in to the resort for booking, Receptionist cant manage with the short time. The checking process is very difficult in the guest departure time because, they cant easily find needed records in this manual system. The stationery costs are high :- There is a lot of paperwork to be done and lots of records of guest, cash books, room details, availability details etc. that have to be maintained, which makes it a very confusing job. Due to the large amount of paperwork that needs to be kept for later reference, there is also need for large storage space. Not only should there be space to store all the records but it should be stored in easy way to find the records and very high cost. It occupies lot of space to locate the file and difficult to search due to the different locations :- Currently, a large number of past and present guest and recruitment related information are stored in cabinets and racks. This way, files get dust collected and confidential papers get loose from the files with time. To maintain the paper in order, filing cabinets, stationary and employee is needed which comes with a cost. Some of these cabinets are kept inside the office congesting working areas and the others are kept in store rooms accruing valuable floor space. Calculation Process :- Also, the calculating process is very difficult such as customer charge calculation (food, Room, facility charges), the resort balance checking. In the manual system for every process there should be needed more workers. Not only cant they work accurately and in the correct. System Development Methodology I have selected the Water fall method model for developing a system for Riviera resort reservation because these models demand a systematic and sequential approach to software development. It presents a highly structured method of software development that starts at the system levels and progress. I am going to develop a resort reservation system which is more complex. This can be handled by using this methodology. And this model decreases the gaps between users and system developers and to increasing systems performance. Waterfall Model This is the most common and classic of life cycle models, also referred to as a linear-sequential life cycle model. It is very simple to understand and use. In a waterfall model, each phase must be completed in its entirety before the next phase can begin. At the end of each phase, a review takes place to determine if the project is on the right path and whether or not to continue or discard the project. Unlike what I mentioned in the general model, phases do not overlap in a waterfall model. Waterfall Life Cycle Figure 1.1 Reasons for selecting waterfall methodology for Hotel Riviera Works well for smaller projects where requirements are very well understood. Easy to manage due to the rigidity of the model each phase has specific deliverables and a review process. Good progress tracking due to clear development stages Phases are processed and completed one at a time. It is suitable for real time and critical system Suitable for small and large size projects. Simple and easy to use. System Requirements Functional Requirement To develop a fully tested Guest update, Room update process, it is asked that the application should allow the user to add, edit find details and handle payments. To accomplish this, it is required to create Access VB (Visual Basic) forms. It necessary to maintain reservation file, guest file, order details files payment file including registration fee in the database. So it is asked to design the necessary interfaces using VB to fulfill the above requirement. To fulfill the above requirements I have created a fully tested reservation system from the knowledge that I have on VB Access. I assumed that resort reservation system need to computerize the reservation process and I have directed my efforts and created a program which is coming out here. Front end Welcome Screen: Welcome screen with user verification facility. This screen will allow the user to type user name and password. This user name will be common for Administration members and another username and password for Manager. Registration of new users: This system should allow registering new users from this organization. Adding details to database: When a Guest comes to register, the system will be added his details to database. Such as name, address, designation, passport number, age, sex and nationality etc. Calculations: Calculations in the system will be found out the due amount. The due amount will be calculated from the requirement the reservation form. Rooms details: Details of rooms can be found in their database. And the system should be able to record their information. The system should assign unique number for each room and allow the user to enter details such as room number, room type, rate and status etc. Banquet details: Banquet reservation also is another function of this resort. So details of banquet can be found in this system. Also the system should be able to record their information. Such as banquet no, location and charges. Engineering details: When customers reserve a hall for a function, they can be found what are the engineering facilities available in this resort for doing that function. Such as Sound system, Overhead Projector and Desktop computer. Foods details: Details of foods also can be found in this system with charges to customers to decide their favorite foods. Such as Egg w/ rice, Spaghetti, Chicken Salad, Coke (Medium) and Fried chicken w/ rice etc. Liquor details: Hotel Riviera has a big bar for their customers. So liquor details are very important for this system. Mainly it should be included description of liquor, price and expiry date. Details of pools: There are two types of pools available. One is adult pool and another one is child pool. Details of pools are most essential for this system. Order details: When purchase orders are made by customers or guests, presently all of them are filed and placed into drawers. But it will be great if the hotel can save those details in the system and be able to retrieve them later if required. Order details will be included ordering meals, and ordering liquor. Room reservation: This requirement is the hearth of this entire system. It is for the purpose of fulfilling requirement that most of the above requirements are met. Fulfilling this requirement will be the key solution in the system to be developed. Once this requirement is successfully tackled, the older access registry room will become obsolete. This system should be able to record details of room reservation number, guest ID, room number, reservation date, date reserved, length of stay, and status. Banquet reservation: This requirement also a very important function of this system. This resort is doing not only the room reservation but also the banquet reservation for their customers. This part should be included banquet reservation no, reservation date, client name, address, contact no, date reserved, starting time, finishing time and status. Search The ultimate purpose of any database system its functionality to support retrieval of data in a way it is expected. This is the case here also. If any reservations details are required, the system will be allowed to find the details from related database and make reservation using search function. Printing facilities Staff should be provided full functionality to printing relevant documents when they needed. Reports In this computerized system, reports will also be a part and parcel they are the means that help get printed outputs here. Staffs should be allowed to run reports and get prints. Common functionality requirements The system will be having a Multiple Document Interface (MDI) through which all the screens and reports can be reached. Colors to be used in the screen should be consistent. Blue with black will be interesting to see. Also buttons on window should be placed in the top of the screen. One window should be used for generating reports i.e. the user should be able to run reports one by one within one window. It can be by clicking on a button, using menus or shortcuts keys. Calendar with one month displayed; whenever there is a need for entering dates, the user should be given facility to pick it from a calendar. Short cut keys should be assigned to expedite the data entry work. There user should be allowed to backup the database to a certain location. This practice ensures the safety of updated data. Printer will be connected to one PC and others will share the printer. Non-Functional Requirements Although these requirements are not directly with the system to be developed, they are very important factors to take into consideration for the development and successful implementation of the system. Under this section I identify non functional requirement within the projects scope. Product Requirement Usability and Efficiency: Since the earlier version of Visual basic (6.0) is going to be used, performance will be high and it is very fast. The system should be very much easy to handle. Reliability: User should easily understand about the system. And they will find it very much handy. Portability: Database should be maintained with much care and give the database to that system in correct format. Operational Requirement Security: database access should be prevented from sight. In addition it should be impossible to access certain parts of the system without the proper logon procedure. This requirement should be strictly enforced at the log on single window or feature under this section. User Friendliness: The system should not be possible for a non- authoritative user to enter a single window or feature under this section. Interoperability: No other system could be intercepted while this system is running on the machine. Software Requirement for Implementation For the development of the new system, the following software packages are recommended to be used. Microsoft Visual basic (6.0) for the interfaces program coding. Visual basic data project will be used for the creation of this system. Is the data Environment, Data list control, Data combo Control, Data grid control, Microsoft- Calendar control and Date time picker control, etc. Microsoft Access 2003 as database back end. Crystal Reports 8.5 for the creation of reports. All the reports will be called within Visual Basic using the Crystal Viewer ActiveX control. Software Tools are Needed to Developed the New System Microsoft Visual Basic 6.0 Microsoft Word 2007 Microsoft Visio 2003 Microsoft Access Adobe Photoshop CS Hardware Requirement for New System The reservation system to computerize their reservation system, a computer system needed the following minimum requirements. Processor : 400 MHz RAM : 128 MB Hard Disk : 4 GB VGA : 32 MB Monitor : 14 Operating System : Windows 2000/xp Software : Microsoft Office 2000/xp Floppy Disk Drive : 1.44 MB 3.5 Summary This chapter provided a detailed description on why Hotel Riviera Needs a web and Visual Basic based System and how online room reservation and computerized reservation System solved the problems they are currently facing with the requirement analysis. Next section gives a detailed description about the system. System Analysis Introduction The tools of a system analysis, which are known as fact-finding methods, are found in the scope of the business application and its end users. Therefore these methods and techniques should be applied efficiently for finer and better results. There are many reasons for fact finding during systems development life cycle, but the most important time is when its system development has begun its basic stages. During the beginning stage the analyst must do the current system, which is being currently used. During these stages, the analyst must gather information on the requirements of the end user. Then when the system designing gets on the way, the analyst must gather, the following:- Facts about report formats. Input methods. Information about the organization. Goals and aims of the organization. Organization structure. Objectives and reasons of functional units. Information about the people. Authority and responsibility of relationship. Job duties. Information about the work. Tasks and workflows. Methods and ways for performing the work. Work times and limits. Information about the work environment. Resources available. Proposed System Descriptions The scope of my project is only reservation. So, Room, facility, needed food booking is will be included in this project. The processes will be started from check in and finished with the check out. Between, these two actions there are some processes available. Those are selecting the wanted room with facilities and food, advance payment; store the guest details, reservation details, charge calculation, payment settlement and report creation. Sometime there maybe cancellation process includes. In this system there will be receptionist, guest, cashier and supervisor involved. The receptionist will operate some the booking process of this application. The guest will select his needed suitable. Cashier will handle all calculation and payment processes. The supervisor will create the reports to the management. The detail information about this computerized Resort Reservation system is included in the DFD ER diagram. In this system my aims is to make the resort reservation System. This is fully secure and fully computerized Features of the New System Handling Customer Details Room reservations Banquet reservations Backup facilities Stores data permanently Security Cancellations Handling Rooms Details Making Payments Features like Update, Searching, Deleting, Editing Record etc Generating different kinds of report. Added Solution to Implement the New System The Data is not long-lasting due to the proper system Even if it is an important data which is been kept in a file, which is not secured, It can be misplaced somewhere. Not only will that it destroy in a particular period. So computerizing the manual system it will be stored in the Database to the computer, so which is more secured. And also we can take the Backup for safety. It is time consuming When the data is in a document, which is inside a file, it is very hard to get the necessary details in that particular time. To search the file it will take some time because they have to see the file page by page. After computerizing the manual system it will be much easier to retrieve the data quickly, this will increase the productivity of Resort reservation system. The stationary costs are very high When the data is maintained in a file or any kind of documents the stationary cost like pen, papers, ruler and files. Deleting, updating and editing also will affect the stationary cost. So after computerizing the manual system we can bring down the cost of stationary, which will economy. If a particular file is lost then the whole data will be loosed If a file is lost then every data regarding that resort information will be loosed which is a big blow for the Resort reservation system. It can happen very easily in this Resort. So we can protect the data by implementing this system. Because we can store the data in a particular database which is more secure. No one can steal any record file because they will have their own login. Without knowing password no one can enter in to the computer. Even they have a back up system. It is not possible to get the necessary Data with in a given time As the data is maintained in a file as manual it is impossible to get the data in a given period. If they want to get particular data then they have to seek one by one page. After computerizing all the data it can be retrieved quickly with the help of Query. So it is making easy to work Calculate the payment very Also, the calculating process is very difficult such as Guest charge calculation (food, Room, facility charges), the resort balance checking. In the manual system for every process there should be needed more workers. Not only cant they work accurately and in the correct time. After that computerizing make easy to work Checking process When more than one guest arrives in to the resort for booking receptionist cant manage with the sort time. The checking process is very difficult in the Guest departure time because, they cant easily find the needed records in this manual system Check Room or banquet availability .after that computerizing easily identifies the room or banquet availability Summary This chapter presented information about the tools of a system analysis, which are known as fact-finding methods, are found in the scope of the business application and its end users and feasibility study about this entire system whether which is accepted or not. Also discussed regard features of this system and value added solution for their earlier systems issues. System Design Criteria Introduction In this part, I have discussed why it is important to have a design method when developing systems. Name and explain some strategies for generating design solutions, simplifying design decisions, evaluating designs, and terminating the search for alternatives, the purpose of design models and the principal categories of design models and summarized some differing perspectives on the nature of design Data Flow Diagram (DFD) Data Flow diagrams are a network representation of a system. They are the corn store for structured system analysis and design. The diagrams use four symbols to represent any system at any level of details the four entities that must be represented are: Data flows: movement of data in the system Data stores: data repositories for data that is not moving Processes: transforms of incoming data flows to outgoing data flows External entities: sources or destinations outside the specified system boundary The DFD shows how, through analyzing data flows, a systems internal processes interact with each other, how the system interfaces with its environment, how the system is partitioned into interacting sub-systems, how an existing or a proposed system can be described in a top-down manner.

Payment process Provide the card to the management guest guest Collect the money from the guest, when they leave from the hotel. Room process Handle the room details. guest guest Keep the room details, bed details and other equipments details. Check the room, if there is anything damage, collect the details, and remove from the room and replace it another. Banquet process Handle the banquet details Keep the banquet details, standard equipment details and additional equipment details. Bar process Handle the bar details Keep the bar details, such as drinks items, chips items. If it is finish, order them. Pool process Handle the pool details Keep the pool details Restaurant process Handle the restaurant details Keep the food items Report generation Handle all the report All the details Report generation Keep whole hotel details and when the administration ask the report, get the print out and give it to them.

There are two goals of the normalization process: eliminating redundant data (for example, storing the same data in more than one table) and en
