ECO 5 CA - Essay Example (Koutsoyannis, 192-199) First degree price discrimination- This incorporates negotiation between the individual customers and the seller for selling each unit of output at its corresponding prices, such that the monopolist can receive entire consumer’s surplus. So long as the price, discriminating manages to reap part of the consumers’ surplus his total revenue will be at the peak level, even if sells the quantity at the intersection point of MC curve with the MR curve. 2) Firms that practice price discrimination decide to charge that price for which the marginal cost is equal to the marginal revenue. Corresponding to that point of equality, we will get another point on the average revenue curve, which will tell us the price that the firm should charge to maximize its profits. Firms can also charge price based on the elasticity of demand. This implies an important fact that a monopolist will always operate in the elastic region of the demand curve. A monopolist will not be able to operate in the inelastic region of the demand curve because he will be getting negative marginal revenue, which is not at all desirable hence, he will operate only in the elastic region. If he operates in two markets where the elasticity is higher on one and lower on the other then he will charge a high price in the high elasticity market than in the low elasticity market. Producers can also decide their pricing strategies based on the marginal cost pricing approach. This means that if the producer operates in two markets and if he finds that the marginal cost of production if higher in the first market then in the second market then he will produce less in the first market and charge a high price in that market but in the second market he will produce more and charge a lower price thereby maximizing his profits. (Price Discrimination). The basis differentiation based on the gender for the

Hypertension in the South Side Essay Example for Free

Hypertension in the South Side Essay The population of the Southside Neighborhood in Chattanooga, Tennessee is roughly six hundred and seventy three people. The races residing in this community are blacks, Hispanic, native Hawaiian and other races. The black community is the largest followed by the Hispanic community. In the population of this community, the males are three hundred and eighty while the females are two hundred and ninety three. In addition to this, in this community, about two hundred and fifty people have hypertension. The people with high blood pressure are mostly the African American adults and the old people as well as people from the Hispanic background. Literature Review Hypertension or high blood pressure basically means high tension or pressure in the arteries. Arteries are vessels that carry blood from the heart to all the organs and tissues of the body. In addition to this, hypertension does not necessarily mean excessive emotional tension though stress and emotional tension can temporarily increase the blood pressure of an individual. The normal blood pressure of a person is below 120/80 and the blood pressure between 139/89 and 120/80 is known as pre-hypertension and a blood pressure of 140/90 or above is considered high blood pressure (Weir, 2006). The top number is the systolic blood pressure and it corresponds to the pressure in the arteries as the heart contracts and pumps the blood forward into the arteries (Weir, 2006). The bottom number is the diastolic pressure and it normally reflects the lowest pressure to which the arteries are exposed to (Weir, 2006). An elevation of the diastolic or the systolic blood pressure increases the risk of developing cardiac disease, renal disease, hardening of the arteries, and stroke and eye damage. These complications of high blood pressure are normally referred to as end-organ damage due to the fact that damage to these vital organs is the result of chronic hypertension. For this reason, the diagnosis of hypertension is vital so that efforts can be made to normalize blood pressure of a person and thus prevent further complications. According to Turncock (2007), the American Heart Association approximates high blood pressure roughly affects one in three people in the U. S. It is also expected that high blood pressure will affect about two million children and teens and this clearly portrays that high blood pressure is a major health problem in America. Hypertension normally tends to rise with age and this explains the reason that some of the old people in the Southside Neighborhood have high blood pressure. Most of these old people in this neighborhood are older than fifty years old. The most common form of hypertension that they have is the Isolated systolic hypertension. This kind of hypertension only occurs when the systolic blood pressure that is the top number is high. About two adults out of three adults in this community over the age of fifty five who have hypertension have the isolated systolic hypertension (Weir, 2006). In addition to this, the African American population in the community tends to have more severe high blood pressure and is likely to have it earlier in their lives according to the Chattanooga Hamilton Health Department. However, most of them are more likely to be aware that they have hypertension and normally get treatment faster than the Hispanic community residing in the Southside Neighborhood. On the other hand, according to the Chattanooga Hamilton Health Department, the members of the black community have higher rates than the Caucasians of other causes of death other than die from hypertension related complications such as kidney failure and stroke (Turncock, 2006). The Southside neighborhood faces some risks that are prone to hypertension in the future. For instance, a significant number of some teenagers in the neighborhood are obese or overweight and this makes them more likely to develop pre-hypertension. Being overweight is having extra body weight from bone, muscle, water and fat while being obese is having a high amount of fat deposits in the body. However, fewer adult women in the neighborhood have hypertension. In the Southside Neighborhood, there is a community asset that supports the local public health system in promoting health and improving the quality of life. This asset is the Chattanooga Hamilton County Health Department. And it has been quite successful in carrying out its mandate. The Chattanooga Hamilton County Health Department main roles are to track and investigate health problems and hazards in the Southside community. It has been quite instrumental in advocating for healthy eating habits in an attempt to curb the high rates of obesity that are quite apparent in most teenagers in Southside neighborhood. The Chattanooga Hamilton County Health Department has collaborated with the Tennessee Department of Health to use the populating health information systems such as the hypertension registries in an attempt to find out the kind of people at risk of contracting hypertension. In the Southside neighborhood, the residents are somewhat exposed to air pollution and this can have an adverse effect on them that may lead to hypertension. Polluted air has a negative effect on a person due to the fact that blood normally per fuses all of the organs and carry beneficial substances and toxic substances to other organs. In most cases, air pollution is the source of materials that may enter the bloodstream through the mouth, nose, skin as well as the digestive tract. Harmful chemicals such as lead, benzene and heavy metals, volatile nitrites, carbon monoxide, herbicides and pesticides. According to Stoto (2000), these substances are known to produce harmful effects on the bone marrow, blood, lymph nodes and spleen. In addition to this, the blood cells of a person are regularly undergoing turnover with new cells entering the circulation as the mature cells are lost thus making the blood system very vulnerable to environmental poisoning. For instance, lead normally interferes with the normal formation of the red blood cells by inhibiting some significant enzymes. Furthermore, lead damages the membranes of the red blood cells and interferes with the cell metabolism is a manner that somewhat shortens the survival of each cell (Swayne, 2006). In addition to this, some airborne chemicals normally stimulate the immune system to activate macrophages and leukocytes that can produce extensive damage to the tissues, especially to the cells that normally line the blood vessels. Therefore, the combined effect of these events is to speed up changes that ultimately lead to hypertension or high blood pressure. Therefore, the health departments in Southside neighborhood, Chattanooga should ensure that the residents do not come across heavy metals such as lead that is commonly found in children toys and they should also carry out epidemiology programs in an attempt to be aware of any diseases that might be detrimental to the community. Additionally, this health department should raise the residents awareness of the chemicals discussed above as they can cause hypertension or high blood pressure. The local public health system, private medical practitioners and other interested parties in the Southside neighborhood should come together and adapt a Less Stress Health Program, which will consist of seven parts. These parts should be plan well, move well, pray well, eat well, sleep well, think well and abstain well. If adapted by this neighborhood, this program can prevent hypertension as well as the other diseases that are normally borne out of high blood pressure such as renal failure. By enjoying life well, moving well and eating well, the residents of the neighborhood can reduce the chances of contracting high blood pressure. In addition to this, this program should help the residents of the neighborhood to lead healthy lifestyles by taking measures such as developing fitness plans, lowering their blood cholesterol, lowering body weigh, improving their sleep, relaxing through spiritual nourishment as well as developing hopeful and positive thinking patterns and support (Rowitz, 2009). In due time, all these factors if taken seriously by the residents of the Southside neighborhood, then hypertension and other diseases can be an issue of the past. Additionally, this program should adapt the four steps to better health. The first step will be to record the health data. Secondly, with the aid of any health educator is to set goals in each area of the neighborhood. The third step should be to start to make some needed changes and create less-stress health seminars that will offer advice to the neighborhood on how best to combat or prevent hypertension. The fourth step would be to repeat the health record after every three and seven weeks in order to efficiently serve the neighborhood with the necessary advice regarding how to live or prevent hypertension (Weir, 2006). Furthermore, this program should hold campaign against unhealthy behaviors such as lack of physical activity, poor diet and tobacco use as they are risk factors for getting high blood pressure. In addition to this, obesity and overweight are risk factors for hypertension and this program needs to cater to the young people in the Southside neighborhood as some of them are already obese and this can lead to hypertension or other serious illnesses. Lately in the Southside neighborhood, private and public programs are being designed to promote healthy behavior among the youth. In addition to this, employers are becoming more aware that obesity and being overweight as well as smoking as these habits are affecting the productivity and health of their employees and in the end, this affects the businesses. The result of this is that innovative employers are providing their workers with a range of work-site –based health promotion and programs that prevent diseases such as hypertension. In the long run, these programs will improve the health of the workers as well as increase their productivity and capitulate a noteworthy return on investment for the employers (Pinger, 2008).

Comparing Mary Shelley’s Frankenstein and Kenneth Branaghs Frankenstei

Comparing Mary Shelley’s Frankenstein and Kenneth Branagh's Frankenstein Most Americans have some idea of who Frankenstein is, as a result of the many Frankenstein movies. Contrary to popular belief Mary Shelley’s Frankenstein is a scientist, not a monster. The "monster" is not the inarticulate, rage-driven criminal depicted in the 1994 film version of the novel. Shelley’s original Frankenstein was misrepresented by this Kenneth branagh film, most likely to send a different message to the movie audience than Shelley’s novel shows to its readers. The conflicting messages of technologies deserve being dependent on its creator (address by Shelley) and poetic justice, or triumph over evil (showed by the movie) is best represented by the scene immediately preceding Frankenstein’s monster’s death. In Shelley’s novel, the final picture of Frankenstein’s monster reveals important qualities of his inner nature; he is shown in the last moments of his life to be felling, fully conscious of his guilt, and firm in his decision to end his life. This is the conclusion of a long series of events providing insight into how the monster changed as a result of his creator’s actions and the actions of the people with whom he came in contact. Up until this final point, he has changed from being good and hopeful to being caught up in the desire for a companion, to being evil and only focused on revenge. All these changes are recounted by the monster himself in this scene. (Blackwood's Edinburgh Magazine) He was at one point motivated by many good things like as virtue and honor, so much so that he wanted a companion to share in his happy life. â€Å"When I first sought it [sympathy], it was the love of virtue, the feelings of happiness and affec... ...iro portrayal of Frankenstein’s monster has created a false myth of an evil, unintelligent monster that is not at all similar to the one Shelley displays in her novel. Not only does the movie spread a false interpretation of Shelley’s work, it provides the public with no lasting message about technology or about the effects of misplaced human love. Shall we then seek revenge? Shall we destroy that what is evil? Of course not--Shelley gave us all to learn a lesson of tolerance and of correcting our mistakes. Perhaps if a more accurate film version of Frankenstein were available to the public, more people would be motivated to read the book and learn Shelley’s powerful message.

What Would You Like to Ask?

A group of British Boys, Marooned on an Island A group of British school-boys find themselves marooned on an island (perhaps in the Pacific Ocean). They were being transported by an aircraft from England to some safer country on account of a nuclear war which had broken out in Europe. When, on the way, the aircraft caught fire the pilot released the detachable passenger-tube carrying the school-boys. The passenger-tube crash-landed on this island, and most of the boys managed to come out of it although some were trapped in the passenger-tube which was soon carried away by the waves into the open sea and lost.At first the boys who have landed on the island get scattered but soon they are able to get together when one of the boys by the name Ralph, having discovered a conch-shell, happens to blow it. Ralph now suggests that the boys should have a chief to guide them and to direct their activities. A boy called Jack, who is the leader of a group of choir-boys, says that he should be acc epted as the chief because he is chapter-chorister and head boy and because he can sing C sharp.But Ralph says that the chief should be chosen by votes. As the majority of the boys are in favour of Ralph, Ralph declares himself as the duly elected chief. Ralph now frames certain rules regarding the holding of meetings of the boys and about the conduct of these meetings. He says that, if anyone wishes to address the assembly at any meeting, he should ask for the conch and should hold the conch in his hands. Ralph Elected as the Chief. His Constructive Suggestion A conflict now begins between Ralph and Jack.Ralph had allowed Jack to continue as the leader of his choir-boys. Jack had the designated his choir-boys as the â€Å"hunters†. Having seen pigs on the island, Jack makes plans to hunt down and kill them in order to obtain meat for boys who feel fed up with the fruit which they have to eat everyday to keep themselves alive and who are craving for meat. Jack is a boy of an adventurous spirit, and the desire to hunt pigs becomes an obsession with him. Jack now begins to hate Ralphs because Ralph’s priorities are different fromJack’s. Ralph insists on the maintenance of the fire and the smoke, while Jack is wholly occupied with the hunting of pigs. Jack, having proved quite successful in his hunting expeditions, has won the support of the majority of the big boys who have come to be known as the â€Å"Biguns†. Jack therefore becomes increasingly defiant towards Ralph. Ralph now develops a liking for piggy who becomes an ardent supporter of Ralph. Jack hates Piggy even more than he hates Ralph. A beast on the Mountain-TopOne morning Sam and Eric, who are twins and who had been put on duty one night to keep the fire burning, come in a state of deep perturbation from the mountain-top and tell Ralph and the others that they have seen a beast on the mountain-top and that the beast had tried to chase them in order to seize them. Ralph, Di splaced By Jack. Simon’s Hallucination In the course of one such expedition, Jack offers the head of a slain pig as a gift to the beast in the hope that would not harm him and his hunters.Simon at this time is at his usual hunt in the forest and witnesses the action of Jack and his hunters and his hunters in offering a gift to the beast. Simon, Killed by Jack’s Hunters Jack has now begun to adopt the primitive method of tribal leaders. He refers to his followers as his â€Å"tribe† and he keeps his face painted all the time with red clay, white clay, and charcoal, asking his followers also to paint their faces in the same way. He has also begun to encourage mock-hunts in the course of which the boys dance and sing and chant certain words relating to their hunting operations and their killing of pigs.Jack and his followers now become more and more callous, with the result that, in the course of one mock-hunt, Simon is killed by the hunters. The hunters, in their frenzied excitement, had taken Simon for the beast and had pounced upon him. Jack does not experience the least regret over Simon’s death. Later, Jack accompanied by a couple of his supporters, raids Ralphs camp and takes away Piggy’s spectacles because he and his supporters need the spectacles in order to light a fire every time they want to roast pig-meat.Jack had now become quite oblivious of the to rescued from island ; but Ralph and Piggy are filling constantly worried as to whether any rescue will come, especially now when the cannot light a fire a fire and keep it burning as a distress-signal to the sailors of a passing ship. Piggy, killed. Ralph’s Life in Danger Piggy feels distraught because, without his spectacles he cannot see anything. He therefore says that he would go to Jack and demand the return of his spectacles. Ralphs thereupon calls jack â€Å"a swine† and â€Å"a bloody thief†.There is an exchange of blows between of blows betw een Ralphs and Jack. Then Piggy speaks and, addressing Jack’s savages, urges them to follow a sensible course of action instead of living like primitive savages. At this point Roger, who has become as savage as Jack, releases a rock from above in order to kill piggy. The Savages’ Pursuit of Ralph. Ralph, saved Ralph hides himself in the forest. But a little later he sees the twins standing guard at the entrance to Jack den. In a state of panic he runs out of the forest towards the beach. He stumbles and falls down on the sand.Thinking that now there is no hope for him, he cries for mercy. On looking up, however, he sees a British naval officer in full uniform standing close to him. Thus Ralph’s life has been saved. The officer says that he would take all the boys home. Ralph now bursts into tears. His whole body is shaken by spasms of grief. He weeps at â€Å"the loss of innocence†, at â€Å"the darkness of man’s heart†, and at the thought o f the death of Piggy who was his true friend. Rescue had come, but two noble-minded and innocent boys have been killed in account of the brutality of jack.Evil had reigned supreme on the island for some time. The Allegorical Significance of the Story Golding wanted to demonstrate that the evil instincts in a human being would rise to the surface and assert themselves as soon as that human being has been liberated from the restraints of civilized. The majority of people in this world are inherently evil. Evil is ineradicable, and it asserts itself as soon as it finds a favourable climate. The favourable climate consists in the removal of the fear of law and in the removal of all those restraints which civilized life imposes upon human beings.

Rain Water Harvesting: A Solution To Water Crisis

Water is an essential resource. No one can live and survive without water. Hence, we should not let the source of the life waste, instead we must store it. We can do so by the methods of Rainwater Harvesting. Rainwater Harvesting refers to the process of collecting and storing of rainwater. Rainwater harvesting helps in providing drinking water, water for irrigation, agricultural purposes or for groundwater recharge. It is one of the best solutions to water problem in the areas having inadequate water resources. Rainwater systems are simple to construct. Usually, rainwater is either harvested from the ground or from a roof. During the rainy seasons, the rain water can be collected and stored in the tanks. There are many methods to harvest the rainwater. Usually, the methods used are: Catchments Areas i. e. the areas which receive rainfall directly. In this, paved areas like roof of a building or unpaved area such as open ground or lawns can be used for the catchment areas. Ground catchment techniques has more chances of collecting water from the larger surface areas. Storage system: It is designed according to the amount of water that is needed to be stored. Storage system must be sealed and does not leak. Chlorine must be put from time to time to keep the water clean. Conveyance systems which transfer the rainwater collected on the rooftops to the storage tanks and that is done by making connections to one or more down-pipes connected to the rooftop gutters or pipes. The gutters must be made as such that if it rain starts,the dirt will be washed into the down-pipe and clean water comes out. Advantages/Benefits of Rain water Harvesting: It is one of the best solutions to water problem in the areas having inadequate water resources Reduction of soil Erosion. Improved quality of ground water. Raising of water level in wells and borewells. Reduction in the choking of storm water drains and flooding of the roads. Rain water flows down the hills in the form of small streams which join together to form rivers and lakes. And this is the important and the natural source of water for the living beings. Some of the rain water percolates down the earth until it reaches the hard surface. There it collects to form a large underground water reservoir. Such water is obtained on digging wells and it is called sub-soil water or ground water. Thus, there are three important natural sources of water besides abundantly available sea water. The sea water being saline can not be sued as such either for industries or for domestic consumption. (a) Rain water or snow water. (b) Surface water (river, lakes, streams, canals, ponds, etc. ) (c) Ground water or sub-soil water wells and springs. Rainwater Harvesting In urban areas, the construction of houses, footpaths and roads has left little exposed kuchha earth for water to soak in. In parts of the rural areas of India, flood water quickly flows to the rivers, which then dry up soon after the rains stop. If this water can be held back by storage or by reducing speed of flow, it can seep into the ground and recharge the ground water supply. This has become a very popular method of conserving water especially in the urban areas. Rainwater harvesting essentially means collecting rainwater on the roofs of building and storing it underground for later use. Not only does this recharging arrest ground water depletion, it also raises the declining water table and can help augment water supply. Rainwater harvesting and artificial recharging are becoming very important methods. It is essential to stop the decline in ground water levels, arrest sea-water ingress, i. e. , prevent sea-water from moving landward and conserve surface water run-off during the rainy season. Town planners and civic authority in many cities in India are introducing by-laws making rainwater harvesting compulsory in all new structures. No water or sewage connection would be given, if a new building did not have provisions for rainwater harvesting. Such rules should also be implemented in all the other cities to ensure a rise in the groundwater level. Realizing the importance of recharging ground water, the CGWB (Central Ground Water Board) is taking steps to encourage it through rainwater harvesting in the capital and elsewhere. A number of Government buildings have been asked to adopt water harvesting in Delhi and other cities of India. All you need for a water harvesting system is rain, and a place to collect it. Typically, rain is collected on rooftops and other surfaces, and the water is carried down to where it can be used immediately or stored. You can direct water run-off from this surface to plants, trees or lawns or even to the aquifer. Some of the benefits of rainwater harvesting are as follows: I. Increases water availability II. Checks the declining water table III. Is environmentally friendly IV. Imporves the quality of ground water through the dilution of fluoride, nitrate, and salinity V. Prevents soil erosion and flooding, especially in urban areas

Daniel Erasmus and the strategic merging of internal and external planning within organisations Introduction Daniel Erasmus and the strategic merging of internal and external planning within organisations IntroductionReferences:Related Introduction Daniel Erasmus (2008), stated that, scenarios is the process which merge inside and outside planning within organisations in order to create a new strategic planning to the future. However, scenario planning created in 1960 by shell group planning ina; order to become the eyes that perceive the prospect of the world future outside the organisation, by showing the right direction that most influences the company environment. Therefore, it is described as a graphic with is detailed and probability view of how the business environment of the company will develop in the future according to the performance of the group and influences, (Lynch 2003). Moreover, (kotler 2003) also argues that scenario planning as the stability of creating possibility illustration of the company prospectively future in different theories about motivating the market as well differentiations suspicions. According to Kippenberger, (1999), private and public organisations both derive the business environmental that is diversity. Whereas, the companies have to be prepare in order to cope with variety changes internal and internal and they must to become to perceive the image about the changes in the future possibility within the business environment. Nevertheless, business must to consider using one scenario prospect as strategic planning, so it will then be possible to have visionary of what might happen and having the solutions to solve problems, this will allows the company to create their own business strategies.

a compromise for the future essays

a compromise for the future essays As America enters the new millennium, our nation faces an enormous challenge. This challenge is to enable the economic expansion of recent years to continue and to reach even higher levels of prosperity. In order for this to happen, many factors will have to be examined and new policies must be implemented that will help the economy strive. In an era that has seen many changes in the regulatory policies of the American government, the future must hold an atmosphere of open-mindedness that will encourage cooperation between the major industries and those people on capital hill. They will decide what direction regulatory policies will travel towards in the new century. In the past, U.S. policy towards big industry has been aimed at giving the average consumer an edge against those companies that seek to reap the profits of business by digging deep into the pocket books of Americans. The first industry to be targeted by regulatory policies was the railroad industry. Starting with the creation of the Interstate Commerce Commission in 1887, the government decided to try and prevent the monopolistic exploitation of passengers by limiting fares and routes as well as entrance into the market. At the time, there were no interstate highways, no buses, and no airplanes to compete with the railroad companies. A century later, this became a matter for deregulation because railroads were not able to compete with these alternate forms of transportation that arose. The evolution of the railroad industry, as well as the regulations imposed on it, are perfect examples of why policy makers need to have an open mind when deciding on today's regulat ory policies. We live in a time that is witnessing an unprecedented surge in technology and innovation. Therefore, thinking about regulating, or for that matter deregulating industry, should not be taken lightly. As the 21st century begin ...
