Discussion post - Essay Example Common symptoms of acute bronchitis include; persistent cough which lasts for about 10 to 20 days which creates clear mucus. While for pneumonia includes; high fever, chest pains, and shortness of breath. The acute bronchitis affects the lower respiratory tract while pneumonia affects the upper respiratory tract (US Department of Health & Human Services, 2011). I agree with Christopher Johnson on the need for the patient to find someone to guide her through some positive lifestyle changes. The signs and symptoms by the patient indicate she is suffering from chronic bronchitis. The recommendations made after diagnosis will help the patient to get well soon and manage the sickness. I also agree the patient needs to be given lessons on antibiotics intake. The patient needs to be encouraged to take the flu and pneumonia vaccines (Cunha, 2014). I agree with Peng Anderson from the patient’s symptoms she has emphysema which is manifested by her history of tobacco use and physical examination (WebMD, 2014). The patient needs to know the severity of the condition and make changes. She needs to control her tobacco use in order to slow the progression of emphysema. I also agree a social worker would be of great help to the patient in locating and utilizing community

Beryls Chocolate Essay Example for Free

Beryls Chocolate Essay Chocolate is a key ingredient in many foods such as milk shakes, candy bars, cookies and cereals. Chocolate is a processed delicacy made from the beans of the cocoa tree. The cocoa tree, native to the tropical Amazonian forests, is an evergreen tree of the cola family. Chocolate is a mixture of roasted cocoa, cocoa butter, and very fine sugar. Unsweetened or called bitter chocolate is available in squares and is the natural rich chocolate ground from the cocoa beans. It has a full-bodied flavor and is ideal for baking and cooking. Sweetened chocolate and chocolate with various other ingredients are also increasingly available. As we know, the type of chocolate refers to three types which is milk chocolate, plain chocolate and white chocolate. History Of Chocolate The Timeline 2000 BC, Amazon: Cocoa, from which chocolate was created, was said to have originated in the Amazon at least 4,000 years ago. Sixth Century AD: Chocolate, derived from the seed of the cocoa tree, was used by the Maya Culture. Maya called the cocoa tree cacahuaquchtl †¦ ‘tree’, and the word chocolate came from the Maya word xocoatl which means bitter water. 1200, Aztec Culture: The Aztecs attributed the creation of the cocoa plant to their god. In both the Mayan and Aztec cultures cocoa was the basis for a thick, cold, unsweetened drink called xocoatl†¦ believed to be a health elixir. Since sugar was unknown to the Aztecs, different spices were used to add flavor, even hot chili peppers and corn meal were used! Aztecs believed that wisdom and power came from eating the fruit of the cocoa tree, and it had nourishing, fortifying, and even aphrodisiac qualities. The Aztec emperor, Montezuma drank thick chocolate dyed red. The drink was so prestigious that it was served in golden goblets that were thrown away after only one use. 1502, Columbus landed in Nicaragua: On his fourth voyage to America, Columbus landed in what is now called Nicaragua. He was the first European to discover cocoa beans being used as currency, and to make a drink, as in the Aztec culture. 1513, A slave was bought for Beans: Hernando de Oviedo y Valdez reported that he bought a slave for 100 cocoa beans. It was at this time, the name of the drink changed to chocolatl from the Mayan word xocoatl and the Aztec word for water, or warm liquid. 1519, Hernando Cortez began a Plantation: Hernando Cortez conquered part of Mexico had a vision of converting the beans to golden doubloons. While he was fascinated with Aztecs bitter, spicy beverage [he didn’t like the cocoa drink], he was much intrigued by the beans’ value as currency. Later, Cortez established a cocoa plantation in the name of Spain. 1528, Chocolate Arrived in Spain: Cortes presented the Spanish King, Charles V with cocoa beans from the New World and the necessary tools for its preparation. And no doubt Cortes taught him how to make Chocolate. 1544, Dominican Friars Got into the Swing: Dominican friars brought a delegation of Mayans to meet Philip. Spanish monks, who had been consigned to process the cocoa beans, finally let the secret out. It did not take long before chocolate was acclaimed throughout Europe as a delicious, health-giving food. The beans were still used as currency. 200 beans bought a turkey cock. 100 beans was the daily wage of porter, and would buy a hen turkey or a rabbit. 3 beans could be traded for a turkey egg, a new avocado, or a fish wrapped in maize husks. 1 bean bought a ripe avocado or tomato. 1657, even London succumbs: Londons first chocolate shop was opened by a Frenchman. London Chocolate Houses became the trendy meeting places where the elite London society savored their new luxury. The first chocolate house opened in London advertising this excellent West India drink. 1674, Eating solid Chocolate was introduced in the form of chocolate rolls and cakes, served in chocolate emporiums. 1704, The Germans imposed a Tax on Chocolate: Chocolate made its appearance in Germany, and Frederick I of Prussia reacted by imposing a tax. Anyone wishing to pay homage to its pleasures had to pay two thalers for a permit. 1765, First Chocolate factory in the USA: The production of chocolate proceeded at a faster pace than anywhere else in the world. It was in pre-revolutionary New England. 1800, Chocolate was an Industry: Antoine Brutus Menier built the first industrial manufacturing facility for chocolate. 1819, the pioneer of Swiss chocolate-making, Francois Louis Callier, opened the first Swiss chocolate factory. 1828, The Cocoa Press was invented by Conrad Van Houten: The Press helped to improve the quality of the beverage by squeezing out part of the cocoa butter. Drinking chocolate had a smooth consistency and a more pleasing taste. 1830, The Drink Became a Confection: Solid eating chocolate was developed by J. S. Fry and Sons, a British chocolate maker. 1849, Cadbury Brothers Exhibited Chocolate: The exhibition was at Bingley Hall at Birmingham, England. 1851, Marked a First for Americans: Queen Victoria’s husband, Prince Albert orchestrated The Exposition in London. It was the first time citizens of the United States were introduced to bonbons, chocolate creams, hard candies (called boiled sweets), and caramels. 1875, Milk Chocolate Came of Age: After eight years of experimentation, Daniel Peter from Switzerland put the first milk chocolate on the market. 1879, Chocolate Literally Melts in Your Mouth: Rodolphe Lindt of Berne, Switzerland, invented conching, a means of heating and rolling chocolate to refine it. After chocolate has been conched for 72 hours and more cocoa butter added to it, chocolate became fondant and melted in mouth! 1913, A new Star is Born: Jules Sechaud of Montreux of Switzerland introduced the process for filling chocolates. 1923, The CMA was established: The Chocolate Manufacturers Association of the United States of America (CMA) was organized. 1925, Cocoa is Big Business: The New York Cocoa Exchange, located at the World Trade Center, was begun so that buyers and sellers could get together for transactions. 1938, World War II: The U. S. government recognized chocolates role in the Allied Armed Forces. It allocated valuable shipping space for the importation of cocoa beans which would give many weary soldiers the strength to carry. Today, the U. S. Army D-rations include three 4-ounce chocolate bars. Chocolate has even been taken into space as part of the diet of U. S. astronauts.

Of Mice And Men :: essays research papers

â€Å"Of Mice and Men† was written bye John Steinbeck and is a fictional book. â€Å"Of Mice and Men† is a book about two life long friends named George and Lennie. They go to a farm to do some farm work after having to run away from their old town Weed. In their new farm, they meet many people including Curley, a little boxer guy who hates big guys like Lennie, and Curley’s wife, who is a tart. Lennie and George have many grand adventures on the farm, but one day while George is out playing horseshoes, Lennie accidentally kills Curley’s wife. Lennie runs away but when the guys come back to find Curley’s wife dead, George is forced to kill his friend. The four people responsible for Lennie’s death are George, Curley’s wife, Lennie, and Curley. The person most responsible for Lennie’s death is George. The reasons why I think this is mainly because George shot Lennie in the end of the book. Also George left Lennie alone in the barn giving Curley’s wife a chance to come and talk to him, and that is when Lennie killed her. George should have given Lennie more instructions on what he was supposed to do while George was out with his friends. The second most responsible for Lennie’s death is Curley’s wife. The reasons why I think this is because she provoked Lennie into talking to her and into petting her hair. She was lonely and wanted someone to talk to, but she also was very flirtatious with Lennie. When she yelled she scared Lennie which made him hold on to her neck harder. Curley’s wife shouldn’t have been flirting and seeking other men while she had a husband. The third most responsible person for Lennie’s death is Lennie himself. The reason I think this is because Lennie killed Curley’s wife, which made George have to kill Lennie. He also has no control over his strength since he was retarded, which is another reason why he died. And more importantly he disobeyed George by talking to Curley’s wife, which George told him absolutely not to do. The last responsible person for Lennie’s death was Curley. Curley was very mean to Lennie and was picking on him for only the reason that Lennie was bigger than Curley. Curley was also very possessive over his wife, which lead her to look for other men.

America Needs Sex Education in Schools Essay example -- Sex Education

Sex education is a major cause of arguments among parents and their school’s board of directors. Some parents argue that sex education should be taught at home or in their religious institution based upon their values. Should the public education system teach sex education to students? There has not been a solution that can be agreed upon unanimously. Sex education isn’t yet a necessity in every school but community support for it is slowly increasing. Sex education needs to be implemented in schools throughout the nation for the protection of today’s youth and further generations from the dangers of unsafe sex and to teach them to understand what sex means. Many problematic situations arise from the current status of sex education in the United States. Almost all of the problems in relation to this idea are results of the youth’s lack of knowledge about sex. Sex education can greatly impact the student’s future by preventing the alarming statistics being created by teenagers.

Recession in American economy Essay

The economic meaning of the term recession is, â€Å"A period of economic decline in a Country, characterized by reduced trade and industrial activity, production decline and increased levels of unemployment. It normally lasts between one and two quarters consecutively†, (Tremblay; 2007). In the US, incidences of recession have occurred since 1854. This paper, seeks address the reasons for recession in the US, with reference to the principles of consumer behavior and the firm as a whole. Observers were not expecting an incidence of recession this time round. Most observers have been persuaded to expect moderate economic growth rates in the US, of about 2 to 3 percent and a moderate inflation of around 2 percent (George. S, 2008). This is due to the fact that the US economy has proved to be the most resilient in the world. They however (the observers), have good reasons to back their predictions; 1. They have placed their hopes on relatively stimulative monetary policy to keep consumption and investment spending up and expect the worst of the housing decline to be over. 2. With stock prices making new highs, some point out that presidential and stock market cycles are favorable to higher stock prices since investing during 27 months before a US presidential election has proved in the past to be more Profitable than investing during 21 months after elections. In the October 16th issue of Headwinds, 2007 for the US economy, it is explained that macro-economic conditions make it a matter of months before the US economy and the dollar begun to experience some downward pressure (recession). This is probably the time for this recession. The US is the country with the highest gross domestic product (GDP) in the world, with a GDP of $13 trillion . This has however reduced in the recent past. Employment levels have also declined. Production levels have gone down owing to cut-throat competition from emerging world producers like China and other Asian Countries. An attempt by the households to save more from a given income led to the decrease in actual amount they succeeded to save-paradox of thrift, (Lachman, 2008). Different reasons can however be put forward to explain the causes of this recession; 1) The outgoing administration’s short term reaction that they gave the economy before the 2004 and 2006 elections through a combination of large tax cuts and large increase in military spending. This ended up being a waste as billions of dollars were spent on a futile war (Trembley, 2007) 2) Record budgetary and current account deficits have severely neutralized the federal monetary policy attitude, because interest rates cannot be reduced substantially for fear of a collapse of the US dollar from the federal budgetary deficits as they are being reigned on. (Lachman, 2008) 3) With all this taking place at the same time that the construction industry is in disarray and housing prices have tapered off or are declining. Be that as it may, it is important to note that home ownership is more widespread than stock ownership; slightly more than two thirds of Americans own their homes, while less than half own equities. The objective of the households is to maximize utility. By spending more on home ownership than on stocks, utility is attained quickly and it is within the consumers budget space (Ingdahl, 2008). 4) This rules the question of how long the American consumer will keep up the high pace of spending in such a context. During the years of the housing boom, consumer spending was driven by the accumulation of wealth and record consumer indebtedness, most of it in the form of mortgages as the price of houses increased. Now that the reverse is occurring and banks and other loaners are reclaiming property for unpaid debts, a retrenchment in consumer spending cannot be ruled out (Trembley, 2007). 5) Protectionist push from the Democrat controlled congress, risks putting in jeopardy the flow of capital of about $2 billion a day that the US economy is borrowing from abroad (mainly from China and Japan). Trade frictions between the US and China could force banks to raise interest rates and not lower them. In any case, the banks would not lower the interest rates as expected to make up for the housing crisis (Trembley, 2007). 6) Collapse of one and possibly several major financial institutions under the pressure of bad loans and record foreclosures (take possession of somebody’s property usually because they have not paid back an agreed part of the loan). Particularly at risk is the sum $2. 5 trillion mountain debt concentrated in sub primes and loans. One major sub prime lender, (New Century Financial) filed for bankruptcy protection. Others are likely to follow suite because 2007 was the year when a large number of sub prime real estate locus had to be renegotiated at higher interest rates. Foreclosures rate is bound to shoot upwards. This will culminate in the next few years into a financial hurricane (Trembley, 2007). 7) The seventh and final reason is a geopolitical factor. The outgoing US administration has created some tension between the US and some countries in the Middle East. The Middle East, is the world’s largest oil producing region. In the coming years, the world economy will have to adjust to a peak in oil production and higher prices after the current lull. Geoplitical mistakes made by the outgoing administration have turned the richest oil producing region into a hot war zone making the US economic situation disastrous (Lachman,2008). The above listed reasons shed some light on why the US economy could be undergoing some kind of recession. They however do not provide a conclusive explanation or reasons as to why the American economy could be in recession. Unlike other forecasts, one can only tell when recession started and ended after it has ended. The determination of recession is left to the National Bureau of Research (Campbell. R. M & Stanley. L. B, 2005). However, it is possible to tell whether or not the economy is in recession by looking at past cases of recession. The great depression was the worst economic slump ever in the U. S history. It began in 1929 and lasted for close to a decade. Just like a recession, many factors led to the great depression; however, the main cause for the great depression was a combination of the greatly unequal distribution of wealth throughout the 1920’s and the extensive stock market speculation that took place during the latter part of the same decade. Money was distributed disparately between the rich and the middle-class, between industry and agriculture within the United States, and between the U. S and Europe. This imbalance of wealth created an unstable economy. The excessive speculation in the late 1920’s kept the stock market artificially high, but eventually lead to large market crashes, (Gusmorino, 1996). Almost eighty years later, the U. S might be facing the same situation though not as severe as it was then. Wealth disparities are all over the world today. Although the worst cases are not experienced in America, cases of unequal distribution of wealth are still in America. As mentioned earlier, the American household does not invest much on stocks but in acquisition of homes. Speculations in the stock market are relatively high though not as high as it was then. It is not easy to conclude that the American economy is in recession. Whether or not there is a recession, depends on both on actual economic activity and economic analysis in the future. The facts as they are right now, show that the American economy is in recession. REFERENCES. Campbell, R. M. & Stanley, L. B. (2005). Economics: Principles, Problems, and Policies.

Septic Shock Essay Example

Septic Shock Essay Example Septic Shock Paper Septic Shock Paper In this essay septic shock and Its complications will be analyzed wealth the Immunological, gastrointestinal, cardiovascular, respiratory and renal (Including the acid-base) systems. This essay will contain the general discussion of homeostasis and will study the homeostasis responses to septic shock In each system. Sepsis and Septic Shock sepsis may be defined as the state In which a person Is suffering from an Infection that causes a number of important physiological changes: namely high fever and pulse, elevated respiratory rate, and elevated white blood cell count. Sepsis occurs when the body mounts a massive immune response to an infection. Usually the infection is caused by a bacteria that emits a toxin which causes the immune response. The problem is that the same chemicals that the body uses to fight the toxin also cause negative effects on the circulatory system, eventually leading to lowering of blood pressure and hypertension of the vital organs. This is illustrated well in our example with Mrs.. Little who shows the characteristic increase in pulse and fall in blood pressure. This is causing hypertension of key organs, such as the rain and lungs, which is resulting in some of the symptoms of early septic shock such as shortness of breath and confusion. Septic shock is said to exist when the patient is unable to maintain blood pressure despite all resuscitation efforts and the hypertension is causing end organ damage. Unchecked, septic shock can cause numerous problems including multiple organ failure and respiratory failure (Health A-Z). Indeed, Mrs.. Little is in grave danger. In fact, septic shock is the most common cause of death in hospital critical care units. In the United States septic shock counts for 100,000 deaths per year (Traitor Grosbeaks). Ironically, hospital treatment itself may often be the cause of septic shock, as It is often seen In severely Ill patients with suppressed immune systems (for example cancer patients on chemotherapy) who contract an Infection while undergoing treatment. Homeostasis: The human body internal environment Is composed of cells, tissues, organs and other systems (Martini). External surroundings continuously affect the body Internal environment and the human body must use homeostasis control mechanisms to malting a stable environment. The majority of Illnesses which affect homeostasis are mild and temporary (such as a mild or moderate fever however at times, when serious changes in the body occur, the alteration of homeostasis may become Intense and prolonged and in some instances may even fail and result in death. In order to prevent tons Trot unappealing positive Ana negative Teacake systems allow ten DOD condition to be repeatedly monitored, evaluated and changed (Traitor Grosbeaks). Feedback systems include three basic components; a receptor, a control centre, and an effecter. Receptors are an important part in feedback systems because they monitor changes within controlled conditions (blood pressure, body temperature, blood glucose level, etc. ). Any disruption in a controlled system (stimulus) then sends nerve impulses or chemical signals to the control centre. At the control centre the body recognizes the set values that the controlled conditions should be at and that processed information is then sent to the effecter in ways of nerve impulses, hormones or other chemical signals. The effecter then responds to the information sent from the control system and any changes that need to be made to the controlled condition occur. When information is received by the control centre it can send an output to the effecter in one of two ways. It can either oppose the change in the controlled condition which displays a negative feedback loop or it can reinforce the change which occurs in a positive feedback loop (Traitor Grosbeaks). Negative feedback systems are involved in the majority of homeostasis control loops because they stabilize and reverse a change in a controlled condition which is usually what the body wants to achieve in homeostasis (Patten). When a receptor detects a change in a controlled condition it sends an input to the control centre. In a negative feedback system the control centre will recognize the problem that has occurred and will alter the controlled condition back to its regular state. Some examples of negative feedback systems include blood pressure and body temperature. The negative feedback system will regulate blood pressure and body temperature back to its normal state that it should be within the body. However in positive feedback the outcome is the opposite. Although both feedback systems work in the same way positive feedback systems strengthen and reinforce the problem rather then oppose he change (Traitor Grosbeaks). Positive feedbacks are not as common in the body but they still play a very important role. Unlike negative feedback systems that bring the body back to its normal state, positive feedback systems send output from the control center to the effecter that will enhance the change in the body. The action of the positive feedback system will continue until it is interrupted by some mechanism outside the system. Positive feedbacks become important in situations like child birth and blood clotting. In blood clotting platelets are enforced to rapidly stick together. Although this is usually abnormal, it is important that this occurs so that blood can clot and serious bleeding is avoided. Another example of a positive feedback mechanism is child birth, where levels of the hormone extinction are increased by the brain in response to stimulation of the womans cervix by the baby. Extinction causes the smooth muscles of the uterus to contract more forcefully, further stimulating the cervix, causing more oxidation to be released, and so on until the baby is delivered In order to survive, every living organism must maintain homeostasis (Martini). To regulate changes that may occur to the body (Martini). When problems such as septic shock occur, proper homeostasis is crucial to survival. However, in septic shock bacteria and toxins can have a big impact on the human body and if homeostasis can not be maintained and the problem is not caught early enough homeostasis can become seriously altered, and death can ensue. Immune System: Malignantly instantaneous requires ten correlated efforts AT many Day mechanisms and systems. One such system is the immune system, which is designed to ward off millions of disruptive pathogens that may assault our bodies such as bacteria, virus and parasites. The immune system works closely with the lymphatic system in the body fight against infection. The lymphatic system is responsible for three major primary functions; transporting dietary fluid, draining excess interstitial fluid, and carrying out immune responses (Traitor Grosbeaks, 2003). The lymphatic system is a network of lymphatic vessels transporting fluid called lymph and also contains many structures and organs containing lymphatic tissue. Lymphatic vessels transport lipids and lipid-soluble vitamins (A,D,E and K) to the blood that are absorbed by the gastrointestinal tract (Traitor Grosbeaks, 2003). The lymphatic vessels within this system also drain excess interstitial fluid from tissue spaces and then return it to the blood. The lymphatic capillaries are unique because they permit interstitial fluid to flow into the capillary but not out. The Interstitial fluid enters the capillaries when the pressure of the interstitial fluid is greater then in the lymph. When this occurs the cells slightly separate allowing the interstitial fluid to enter into the lymphatic capillary. However, if the pressure is high in the lymphatic capillaries the cells adhere more closely and the lymph cannot escape back into the interstitial lid. In the case where there is excess lymphatic fluid cells open more widely so that it is able to flow into the lymphatic capillary. This overload of fluid will result in tissue swelling (Traitor Grosbeaks, 2003). The third main function of the immune system is to carry out immune responses. The blood circulating in our body contains three classes of lymphocytes including T cells, B cells, and natural killer cells. T cells destroy foreign cells directly and stimulate or inhibit the activities of other lymphocytes. B cells differentiate into plasma cells and secrete antibodies that rotate us from disease by attacking foreign cells and natural killer cells attack a wide variety of infectious microbes (Martini). Just as these cells destroy foreign cells, two main phagocytes called interruption and macrophages ingest bacteria and dispose of dead matter through a process called phagocytes. Phagocytes is the process in which foreign agents are ingested and destroyed (Traitor Grosbeaks, 2003). An adequate immune system promptly recruits interruption, macrophages, lymphocytes, and antibodies to the site of infection to prevent host colonization. Through histograms these cells neutralize and eliminate microbes and their toxins. However, if these host defenses are overpowered by pathogens septic shock may follow (Cancer nursing). As the process of septic shock advances, it becomes increasingly difficult for the body to maintain homeostasis. The immune system becomes overwhelmed as it frantically attempts to prevent the spread of infection and toxin to other tissues. Moreover, the bacterial toxins hamper the body immune system response. We see in our example how Mrs.. Littlest blood work indicates an elevated white blood cell count, with increased interruption. This is indicative off significant bacterial infection and subsequent inflammatory and immune response (Traitor and Grosbeaks, 2003). Mrs.. Little is displaying systemic inflammation as her body is trying to restore homeostasis by disposing of toxins and foreign material to prevent their spread to other tissues. When this occurs there is movement of phagocytes from the blood into the interstitial fluid and the normal homeostasis mechanism AT railing Interstitial Toll Ana restoring It to near circulating volume cannot be achieved. Her blood pressure naturally falls as her circulating volume is depleted. This results in tissue hypertension and further inflammation. Gastrointestinal system: Nutrients are needed to achieve homeostasis by building new body tissues, repairing damaged tissues and to gain chemical energy needed for our body to function. In order to attain these nutrients the gastrointestinal system breaks down consumed food into molecules through digestion. In order for digestion to take place the digestive system has six basic processes including ingestion, secretion, mixing and propulsion, digestion, absorption and defecation (Traitor Grosbeaks, 2003). These six major functions take place throughout the gastrointestinal tract of the human body. Through the gastrointestinal tract foods are broken down and then the majority of nutrients from these foods are absorbed through the mucosa of the intestinal villa. These nutrients are then passed into the blood or lymph and circulate to cells throughout the body (Married). Since the gastrointestinal system contributes to homeostasis by absorbing water, minerals, and vitamins needed for growth and function of body tissues and eliminates wastes from body tissues in feces there are many blood vessels that allow nutrients to be delivered and wastes to be expelled (Torah Grosbeaks, 2003). In order to carry out all of these functions, the human digestive system must have an extensive blood supply. Thus, in septic shock, and the subsequent drop in blood pressure that ensues, the digestive organs suffer considerable hypertension (cancer nursing and Medicine plus). Because the gastrointestinal system is highly vascular it is more sensitive to the decrease in blood pressure and blood flow and in result there is a decrease in gastrointestinal mobility, and more ominously there can be actual tissue necrosis as portions of the bowel become chemic and die (cancer nursing). Mrs.. Littlest X-ray indicates that she has free air under her diaphragm which almost certainly is a result of this process as her bowels are likely leaking air as they deteriorate from the lack of blood supply. As well as providing nutrients and expelling wastes to maintain homeostasis the gastrointestinal system actually contributes to homeostasis in the respiratory system. The pressure of the abdominal organs within the abdominal cavity actually exerts a pressure against the diaphragm, which helps expel air quickly during a forced exhalation. Any serious injury to the abdominal organs, such as an chemic one, causes less motility in the bowels and even the leakage of air which can both directly affect their ability to support the diaphragm in respiration (Traitor Grosbeaks, 2003). In our example, Mrs.. Little is experiencing abdominal pain which is likely on the basis of hypertension of her gut with subsequent schemas. There may even be direct infection of her bowels and other abdominal organs, causing inflammation and pain. Cardiovascular system: The cardiovascular system consists of three main components responsible for many homeostasis mechanisms in the body. These three components include blood, the heart, and blood vessels. Blood is responsible for transporting substances, regulating processes throughout the body and protecting against disease. The heart then pumps the blood to the body through blood vessels where the blood then exchanges materials needed for the human body regular function (Traitor). Is composed AT two mall types AT cells, wanly assaults ten allover AT materials useful to the body. These two cells include white blood cells and red blood cells. White blood cells (leukocytes) are the main cells of the body that destroy pathogens and any foreign substances entering the body. Among white blood cells, interruption exposed most quickly to bacterial infection. Interruption normally make up 55%-70% of white blood cells while in a complete blood count the normal amount of white blood cells in the blood is 4. 8-10. Xx per liter (traitor). In situations of extreme stress however, such as in a severe bacterial infection, the body releases very immature white blood cells called band cells (named because of their band or horse- shoe shaped nucleus). These band cells will increase the overall number of white blood cells and help to fight the infection. Red Blood cells (erythrocytes), unlike white blood cells, are shaped like biconcave CICS and are highly specialized for oxygen transport. Hemoglobin, which is a major component of red blood cells and serves to assist in the carrying of oxygen, gives erythrocytes their characteristic red color. Hemoglobin is crucial for homeostasis because in order for the body to maintain its regular state hemoglobin must deliver enough oxygen to other parts of the body for proper function. Hemoglobin arises from red bone marrow Just as platelets do. Platelets are also essential to the body because they protect the body by clotting blood after injury so that bleeding stops quickly in a controlled manner (Traitor). Erythrocytes, leukocytes and platelets are all very important to the body but in order for them to reach their targets the heart must pump them through two closed circuits: the systemic circulation and the pulmonary circulation. Pulmonary circulation moves degenerated blood from the right ventricle to the lungs and returns oxygenated blood from the lungs to the left atrium, while the systemic circulation transports oxygenated blood from the left ventricle through the aorta to all organs of the body and then delivers the degenerated blood back to the right atrium of the heart (traitor). In order to pump blood through these circuits there must be a difference of pressure so that blood can flow from regions of high pressure to regions of lower pressure. This force of pressure which is exerted by blood against the walls of the heart is known as blood pressure. Blood pressure is influenced by the elasticity in the vessel walls. The more dilated the vessels are the lower the blood pressure will be (Traitor). The normal blood pressure of a middle-aged adult is 120/might and if it is dramatically decreased or increased blood flow will be disrupted throughout the body (fundamentals). Along with blood pressure, heart rate assists in pumping the blood through the body. The regular heart rate is anywhere from 60 -beats/min. The amount of blood expelled by the heart with each contraction is known as the stroke volume and the amount of blood pumped by the heart in one minute is called the cardiac output. Stroke volume and cardiac output are both directly affected by ones heart rate. In the short term, lowering ones heart rate will lead too drop in blood pressure, while raising it causes blood pressure to increase. In this respect, heart rate is another important homeostasis mechanism (Traitor). In Mrs.. Littlest case, a major disruption of homeostasis within the cardiovascular system has taken place. Shock is a critical medical condition caused by a sudden drop in blood pressure. Septic shock occurs when antitoxins are released from certain bacteria Into ten D stream. I nose toxins Interact Walt our Immune system to cause vacillation and a subsequent drop in blood pressure (Webster). In Mrs.. Littlest case her blood pressure has dropped significantly to 80/might as a result of sepsis. As well, in an effort to maintain homeostasis, her pulse rate has increased to a tachycardia of 120 in an attempt to raise her blood pressure (fundamentals). As hypertension and tissue hypertension continue, the effect on the body organ systems (like we saw with the digestive system) can be profound. We see in our example that Mrs.. Little is confused, has clammy and cold skin and is mildly hypothermia with a body temperature of 35 degrees Celsius. All of these findings can be explained by tissue hypertension secondary to hypertension caused by sepsis. She is confused because her brain is being hypertrophied and is not getting the oxygen it needs to maintain a normal level of consciousness. Her skin as well is hypertrophied, looking mottled and feeling cool to the touch. Her fall in body imperative is likely secondary to skin hypertension, but also to a breakdown in the homeostasis mechanisms in the brain that regulate temperature (cancer nursing). Mrs.. Little is also experiencing some of the characteristic abnormalities seen in the blood as a result of septic shock. While sepsis normally causes an elevation, at least originally, in white blood cell count, often this leukocytes changes to a leukemia, or relative lack of white blood cells, as the disease progresses. Sometimes this interruption is a pre-existing condition, such as with some chemotherapy patients or people with immune deficiency conditions. In other cases the interruption develops as the sepsis worsens and the white cells are used up inn an effort to fight the infection. In any event, interruption is regarded as a serious problem in sepsis since it means that the immune systems ability to fight off the offending pathogen has been overwhelmed. Whereas a normal white blood count is 4. 8-10. Xx per liter Mrs.. Littlest white blood count in our example is 2. , a significant interruption with 70% interruption and 20% bands(Traitor). While the elevated band count does indicate an attempt to fight the infection, because there is a decrease in the white load cells there are still not enough interruption to destroy the pathogens. We also see in Mrs.. Littlest blood that her platelet and hemoglobin levels are falling. This is also a common finding in advanced sepsis and is caused by a varie ty of factors. To begin with, the hypertension and schemas at the tissue level causes a lot of leaking of fluids from the blood vessels and organs. Platelets are used up in an effort to plug the vascular leaks, and hemoglobin is lost as the blood leaks out. As well, the general hypertension directly affects the bone marrow, as do the bacterial toxins. Since platelets and hemoglobin are produced in the marrow, they cannot be replaced at a fast enough rate (Midlines). It is not hard to imagine the significant effect this lack of hemoglobin especially will have on homeostasis as the body systems, already struggling with hypertension secondary to low blood pressure, now have to survive without adequate hemoglobin supplies and thus inadequate oxygenation. Respiratory system: Blood contains many gases that are transported between the lungs and body cells in the cardiovascular system whereas the respiratory is responsible for the exchange of gases, oxygen (02) and carbon dioxide (CA). Gas exchange within our body is very important and occurs in three basic steps: pulmonary ventilation, external respiration, Ana Internal respiration (littoral). Pulmonary ventilation occurs when we inhale and exhale air into the lungs. The air which we inhale is then involved in gas exchange in external respiration. In this process there is an exchange of gases between the spaces in the lungs and the blood in pulmonary capillaries where blood gains 02 and loses CA. After the blood gains 02 through the pulmonary capillaries oxygen is delivered to the tissue cells through the systemic blood in internal respiration. The blood then loses its 02 and gains the CA that is not needed by the body. 02 is a necessity and is used in the body through metabolic reactions where TAP is produced for energy for the body and CA is released. CA may produce an acidic environment toxic to the cells and so it is eliminated right away when oxygen is delivered (Traitor). In order for the blood to deliver oxygen and pick up carbon dioxide it must circulate through the pulmonary circuits as we inhale and exhale. In exhalation as well as inhalation elevation and depression of the diaphragm allows the thoracic cavity to expand during inhalation hen 02 is inhaled into the lungs and contract in exhalation when CA is expelled (Traitor). Abdominal cavities in the GIG tract assist in respiration because it supports the diaphragm so in instances where there are problems in the GIG tract such as in septic shock it may affect breathing if the abdominal cavity can no longer support the diaphragm. Respiration is controlled by respiratory centers that are regulated by nerve impulses being carried to respiratory muscles. This is so rhythm can be modified when certain chemical stimuli measure how quickly and how deeply we breathe (Traitor). Sensory neurons that are responsive to these chemicals stimuli are competitors which monitor CA, H, and 02 levels to ensure they remain constant and respond if they dont (Traitor). If we are not getting enough oxygen to the body or carbon dioxide out of the body these receptors react by either increasing our breathing or decreasing our breathing to stabilize it. The respiratory system is very important in homeostasis to make sure the body is getting the proper amount of gases needed. However, since Mrs.. Little is suffering from septic shock her Apace levels and Papa levels within her arteries are greatly affected. Since septic shock causes hypertension an increased heart rate results. Due to Mrs.. Littlest increased heart rate it is causing an abnormal deficiency in the concentration of 02 in the arterial blood which is also known as hyperemia (Webster). Hyperemia is evident in Mrs.. Littlest 02 sat which are 89% opposed too regular 100% (fundamentals). In her case her Papa levels have become might from her regular McHugh and she is in desperate need for oxygen (traitor). In order for her body to receive the amount of oxygen necessary homeostasis mechanisms cause her to hyperventilate (increased reheating) causing an excessive intake of 02 while eliminating CA. Since CA is being eliminated from her body her Apace levels have also decreased from might to might. Mrs.. Littlest hyperventilation becomes necessary for survival and due to her hyperventilating her respiratory rate is increasing a large amount to breaths/ min from a regular adult respiration rate of 12-breaths/min (Traitor). Hypertension and heart rate have a big impact on Mrs.. Littlest oxygen rates however if there is a fluid build up that develops in the lungs it also inhibits the passage of oxygen from the air into the blood stream. Through Mrs.. Littlest breath sounds few crackles have been heard which shows that she has a liquid build up in her lungs also Known as pulmonary edema. Pulmonary edema can result Trot septic smock due to the increased permeability of the pulmonary capillaries. In septic shock toxins and bacteria are trying to leave the blood through interstitial fluid. Since there are so many toxins and bacteria causing inflammation there is an increase of interstitial fluid which the lymphatic system can not handle. In result the liquid seeps through the pulmonary capillaries which become more permeable due to the toxins and seep onto the lungs (Merck Manual). This fluid in the lungs can become crucial resulting in adult respiratory distress syndrome which is a life-threatening condition. Renal System including acid-base: Acid-base balance within the body is one of the most crucial elements of the homeostasis mechanisms because it regulates pH levels of the body, which is necessary for survival. One main organ of the body that helps maintain pH is the kidneys which are a part of the urinary system. The urinary system consists of two kidneys, two Reuters, one urinary bladder, and one urethra (Traitor Grosbeaks, 2003). The kidneys contribute greatly to the regulation of blood pH which is a (Traitor). The pH of the body indicates the acidity of a solution according to the number of hydrogen ions. The greater amount of hydrogen within a body the more acidic state it is in (below 7. 35) and as the hydrogen count lowers the more basic the solution becomes (above 7. 45) (figure pig. 873 Patton). However, through homeostasis mechanisms the level of pH within our body tries to stay at a stable state between acidic and basic between 7. 35 and 7. 45. These homeostasis mechanisms participating in the regulation of pH include buffer systems, exhalation of carbon oxide and kidney excretion of H+. The buffer systems bind excessive hydrogen ions and prevent acidity within the body (Traitor). If the pH in the body is low and acidic extra hydrogen ions are secreted from the blood into the urine and eliminated from the body. However if the blood pH is to high less amounts of hydrogen ions are excreted through the urine (Patton). As well as hydrogen ions regulating pH HECK also does this by acting as a weak base. With a regular pH of 7. 4 HECK concentration is about meek/liter however Mrs.. Little only has 14. Therefore her pH may be more acidic because her decrease in HECK will not allow any excess basic ions to help regulate the PH. As well as maintaining pH within the body the kidneys are also responsible for regulating blood volume and blood pressure, maintaining blood similarity, producing hormones, regulating blood glucose levels and excreting wastes and foreign substances. Regulating blood volume is very important in homeostasis because adjusting the blood volume in the body also causes a change in blood pressure. The kidneys are able to adjust blood volume by releasing particular amounts of rennin or by conserving or eliminating water in the urine. Therefore if the load volume is to low the kidneys will conserve water to help increase the blood volume as well as the blood pressure which occurs in septic shock (Traitor). Mrs.. Little who is experiencing septic shock is facing the side affects of decreased urinary output because of the result of low blood pressure that occurs in this disorder (medicine). Since blood pressure is so low in the human body during septic shock the kidneys within the renal system conserve liquid to increase the blood volume which in turn will increase blood pressure trying to achieve homeostasis. In result, the kidneys conserve as much liquid as possible causing Mrs.. Little to nave no water to excrete tongue ruler. Mrs.. Little Is also experiencing a slight decrease in her pH level at 7. 15. This is caused in relation to her decrease in urine output. Through homeostasis extra hydrogen ions which cause a decrease in pH are usually eliminated from the body through the urine. However, since Mrs.. Little has no urine output because she is trying to conserve her blood volume as well blood pressure hydrogen ions can not be excreted resulting in her lowered pH (Patton). PH regulation is very important and in result she will be given treatment in order to help he body try and reach a regular homeostasis state. It is very important that she receives treatment immediately because kidney failure may occur which will only decrease urinary output even further (Merck). Conclusion: In conclusion, when external environments affect the body Just as bacteria affects the human body in septic shock homeostasis mechanisms become crucial for ones survival. Through positive and negative feedback systems homeostasis mechanisms must regulate conditions throughout the immunological, gastrointestinal, cardiovascular, respiratory, and renal and acid-base system.

Security Risk Assessment Coursework Example | Topics and Well Written Essays - 1500 words

Security Risk Assessment - Coursework Example There are a variety of risks that a business organization faces when it comes to the implementation of a secure information technology system. This includes loss of information, an attack by internet or computer viruses and malwares, authorized use of data, etc (Vladimirov, Gavrilenko and Michajlowski, 2010). This paper analyzes the various elements that would make the computer system of a business organization to be vulnerable. It also examines the various measures aimed at protecting the computer system of a business organization. A secure computer system must comprise of three major elements, namely recovery, resilience, and contingency (Calder and Watkins, 2010). Under resilience, the critical functions of a business organization and its supporting infrastructure are engineered and designed in a permanent manner. They are designed in a manner that it is impossible for any disruption to affect the functionality of these systems (Bradley and Carvey, 2006). It makes it likely for an organization to maintain its operations in case of a major threat or attack to its computer systems. For instance, a business organization may develop power back up systems, to protect the loss of data or their computer networks from going off, in circumstances where power fails to occur (Harrington, 2005). Business organizations may use solar gadgets and generators to protect their computer systems, in circumstances whereby power may fail. Recovery involves restoring the important features of a computer system or network that failed to function (Bradley and Carvey, 2006). Computer experts may make arrangements aimed at recovering lost data, and making replacements on areas that is needed. This is to ensure that the activities of the business organization are not interrupted in any negative manner (Oppliger, 2000). Contingency involves

Racial and Ethnic Groups in the United States Essay

Racial and Ethnic Groups in the United States - Essay Example According to the 2000 U.S. census, almost 16 million Italian Americans live in the United States. They constitute about 6 percent of the U.S. population. Most are grandchildren and great-grandchildren of the 3.8 million Italian-born immigrants who entered the United States from 1899 to 1924. Some are descendants of Italian-speaking immigrants from Austria, Switzerland, and Latin America. Others are themselves immigrants, including the more than 1 million who came to the United States after World War II ended in 1945. Two-thirds of the Italian American population live in and around major cities in the northeastern part of the United States." (Italian American). Only America possesses the probability of encountering this problem because of countless causes - immigration, preservation of heritage of immigrants, racial and ethnic differences, and cultural differences to name a few. It is apparent that race is about a social construct rather than biological since society has a different set of rules for each racial group. "racism is based on your physical traits. so what you look like, and ethnicity is based on what you identify yourself as. so simplisticly, racial groups are what other people catagorise you in (based on your physical demenor and look, e.g - 'black' 'white' 'brown' 'yellow' 'red' etc...) and your ethnic group is who you identify being, like you might share commonalities with certain ethnic groups for example be very cultural or religious and identify being a 'pacific islander' just because you were not born in the pacific islands or have pacific island parents or any such blood in you, if you feel you identify strongly with that group (for example - bing taught or brought up in a pacific household or around other pacific island families, children, churches etc.)you can identify yourself in that ethnic group (Ethnical groups). Furthermore, there is no alternative conceptualization of race that I would advocate because it is a social construct. This is due to the fact that society has defined what is expected of each racial group, which has nothing to do with biological aspects of being Italian, Mexican or Irish. From there, it has been apparent that Italian Americans have been a dominant ethnical group because of their food and their place in politics within American culture. Therefore, it seems that the Italian mafia has an upper hand in American politics, which gives them a higher rank than the Russian mafia in America. With that, in America, it is apparent the Italian mafia has skills that fit the labor union, which gives them an inside to American politics. Few Italian Americans today identify closely with Italy. Even fewer read Italian literature, follow Italian politics, or belong to organizations that promote Italian culture in the United States. However, many remain in touch with family or friends in Italy, and many more socialize with other Italian Americans in the United States. Among themselves, Italian Americans still recognize cultural differences rooted in the distinctive regional cultures of northern, central, and southern Italy, and Sicily. The majority of Italian Americans belong to the Roman Catholic Church. However, almost half of recent generations have intermarried with Catholics of other ethnic backgrounds or with people from different denominations, such as

Iraq invasion 2003 Essay Example | Topics and Well Written Essays - 1750 words

Iraq invasion 2003 - Essay Example American invasion of Iraq has been assessed and reassessed by intellectuals both inside and outside America. Though different people put forward different factors as the reasons behind the invasion, all agree on the fact that America failed to achieve any of its objectives in Iraq. Also, it becomes evident from the circumstances that America was in the dire need of strengthening its geopolitical dominance in the Middle East, and considering the situation of the time, Iraq was the most vulnerable victim. There were three main factors which can prove that the American invasion of Iraq was inevitability. They are the US global grand strategy, the US strategic position in the Middle East, and the ruling coalition in the Bush administration. The motivating factors – the war was inevitable In order to understand the American desire to use coercion as a weapon to ensure American dominance in the world, one has to read The Project for a New American Century. The Project’s State ment of Principles declares that America has a pivotal role in maintaining peace and security in Europe, Asia, and the Middle East. Also, it is pointed out that it is important to act before crises emerge, and to face threats before they grow stronger (New American Century, 2000: 4-5). Very similar are the claims in the 2002 National Security Strategy which clearly state that threats to the US would be met using both traditional containment and preventive wars (The White House, 2002: 15). One has to remember the fact that the US global hegemony was, to a great extent, dependent on its protectorate over the oil reserves in the Middle East. Ironically, the biggest threat to American domination also came from the same place; and the best example is the 9/11 attack. Thus, it was clear that America had to reshape the Middle East. In fact, American hegemony over the Middle East oil was getting questioned. In the opinion of Hinnebusch (2007: 213), US and other capitalist countries would im minently face an oil shock as the oil producing Middle Eastern nations were gaining more and more power. First of all, despite the American efforts to impose sanctions on Iraq and Iran, they managed to survive as such sanctions only benefited other nations. To illustrate, Iraq started selling oil concessions to nations like Russia, China and France. Similarly, according to Cramer and Thrall (n.d.: 18), the whole Western Europe wanted to get oil from Iran instead of isolating it; and when America tried to keep its companies away from the so called nations, its rivals were benefiting from the sanctions. Traditionally, Saudi Arabia was playing an important role in providing US with oil help. It moderated oil prices for America throughout the years. However, America was fully concerned about its high degree of dependence on Saudi Arabia for oil needs. Also, the recent years witnessed a decline in the oil pumping capacity of Saudi Arabia making it unable to moderate oil prices anymore (C ommittee on Foreign Affairs House of Representatives 2007: 8). Evidently, al Qaeda and other terrorists were highly dissatisfied with use of American forces to protect Saudi Arabia, and was a motivating factor for Bin Laden to turn against America. As Reno (2012: para. 12-13) points out, it was revealed that Saudi citizens were involved in the 9/11 attack and funding; and this was sufficient for the Zionist lobby in the Bush administration to create an anti-Saudi public opinion in America. Murphy (2011: para. 12) states that, at the same time, Saudi Arabia started looking for alternatives as it felt abandoned by the US. Soon, it reconciled with Iran and Iraq. Thus, as America was losing one swing producer, it wanted to find another one; and Iraq became the primary target (ibid). First of all, it meant that America would again get access to privileged oil, at the same time ensuring its hegemony over its economic rivals like Europe, Asia and the emerging global rival China. Thus, Iraq became a one word solution. The matter can be seen in the military

Accounting Cycle Description Essay Example | Topics and Well Written Essays - 500 words

Accounting Cycle Description - Essay Example The AIS or the accounting Information system used within the organization must be well equipped to understand the unique requirements of the revenue cycle which puts an overall effect on the generated revenues through production and etc. The maintenance of the revenue cycle is a complex procedure, because of which getting complete repayment of your cash is not possible with conventional techniques. In order to collect 100% out of revenue cycle an organization must use an integrated accounting information system that effectively includes people, monetary processes, and technology. The benefits of integrated revenue cycle helps in maintaining internal controls (misappropriation etc.). Use of weak or disintegrated information system with in the organization can also be a cause of trouble in several ways. It could be a disrupting aspect in the revenue cycle that could affect the over all cash flow of the organization. (Avisena, 2009) Information systems are continually altering and developing as skill and technology persists to develop. There is various information systems used within an organization which helps it to run the daily business accurately. The various types include transaction processing systems (TPS) which is a system that gathers, accumulates, adapts and recovers the transactions of a project. Decision Support Systems (DSS) is a system that chains dealings and managerial decision-making actions. A well-designed DSS is a software-based scheme projected to help decision makers accumulate helpful information from untreated data, individual knowledge, documents, and business representations to recognize and resolve problems and take decisions. Expert system is software that efforts to imitate the presentation of one or more human specialists, most frequently for a specific problem area, and is a

In order to make possible information system design, the SSADM technology relies on waterfall model to reach the destination. The SSADM can be originate as a core element for defined documented approach regarding system designing and help to evaluate an updated Rapid Application Development procedure such as DSDM. Dur ing development and growth, the SSADM is following a waterfall life cycle model that incorporates physical design stage study. In addition, the analysis stage includes intense association needs in SSADM. From every stage, the users are prepared to sign off guaranteeing that the requirements are satisfied. Furthermore, a number of illustrative representations related to the system are provided to the users in order to ensure better data understanding. The development projects related to the SSADM are further divided into series of phases, units, periods and tasks. Moreover, the data modeling is considered as a first model that is developed in SSADM. 2 SSADM Aims and Objectives In order to identify and classify projects that are suitable for SSADM project management, the SSADM will offer a framework. The SSADM in reality separates the projects that are related to the project development into small elements, project steps and procedures. The objectives of SSADM are mentioned below: Pro ject management is enhanced along with connected institutions. Better and improved usage of both skilled and unskilled employees. Enhanced and important systems are guaranteed. Employees’ loss is considered in all projects. Projects are assisted by computerized tools such as, integrated application engineering systems. A framework is formed for improved communication between the members of project. This framework incorporates all the tools related to the software development life-cycles, production stages and physical application design. 3 SSADM Advantages and Disadvantages SSADM leverages many benefits by using different techniques for determining visibility and capability of information systems. These techniques are considered as one of the major benefits of SSADM. Moreover, the identification of entities along with their relationships established within the system is tested by logical data modeling techniques. Moreover, logical data modeling technique shows changing data f rom its original state to the updated one. Furthermore, it also holds space for entities that are transmitted via routes that manages data flows within the system. Moreover, credentials pertaining to event modeling define the entities and their impact on business information systems. Consequently, these techniques encompassing perspectives and processes provides the most complete and to the point model.

Accounting Cycle Description - Essay Example The AIS or the accounting Information system used within the organization must be well equipped to understand the unique requirements of the revenue cycle which puts an overall effect on the generated revenues through production and etc. The maintenance of the revenue cycle is a complex procedure, because of which getting complete repayment of your cash is not possible with conventional techniques. In order to collect 100% out of revenue cycle an organization must use an integrated accounting information system that effectively includes people, monetary processes, and technology. The benefits of integrated revenue cycle helps in maintaining internal controls (misappropriation etc.). Use of weak or disintegrated information system with in the organization can also be a cause of trouble in several ways. It could be a disrupting aspect in the revenue cycle that could affect the over all cash flow of the organization. (Avisena, 2009) Information systems are continually altering and developing as skill and technology persists to develop. There is various information systems used within an organization which helps it to run the daily business accurately.

Two approaches to parenting Essay Example | Topics and Well Written Essays - 250 words

Two approaches to parenting - Essay Example On the other hand, authoritarian parenting is unresponsive and totalitarian in nature. This implies that while authoritative parenting is indulgent or permissive, authoritarian parenting is neglectful. While authoritarian parenting features child-focused approaches that have high anticipations of maturity, authoritative parenting understands how children feel and teaches how to regulate the feelings (Bernstein 38). Authoritative parents also encourage independence but still limits and controls children’s actions. While children are required to follow rules in the two styles, failure of which results in punishment, the authoritarian style is less democratic than the authoritative style (Bernstein 69). This is because punishment in authoritarian parenting is not explained, meaning children may not know exactly what they were punished for. On the other hand, authoritative parenting is more responsive to children, ready to listen to and answer questions and explain the purpose of punishment. Further, authoritative parents are more likely to forgive and nurture their children rather than punish them in the event of not following rules. Finally, children brought up in the authoritarian style are likely to develop less social competence than those brought up in the authoritative style because they lack self-confidence. On the other hand, authoritative parenting will most likely build higher self-esteem and develops democratic values (Bernstein

Christianity and Justice Essay Example for Free

Christianity and Justice Essay Christianity emphasises justice, while others emphasise compassion; this statement is fundamental in the belief of Christians. Justice means to have moral rightness that is based on ethics, civil laws, natural laws and religion. One of the Ten Commandments states, Love thy neighbor as thy self. This Statement was repeated seven times in the Bible, once in the Old Testament and six times in the New Testament. It is quite clear to me that our capacity to have this kind of love must be foremost in the mind of God, this also demonstrates that all individuals should be treated equally and as you would like others to treat you. Justice equated to equality. The Christian bible has many examples from both the old and New Testament that gives examples of Jesus wanting all his followers to treat each other in a just way. E. g. when he came across a lady who had been caught in the act of adultery and the crowds wanted to stone her to death and Jesus reminded them that they were all guilty of sin and they he who had not sinned should cast the first stone. Jesus throughout the many encounters with believers and non-believers has spread the message of justice and peace. In Isaiah 56:1 this is what the Lord says â€Å"Maintain justice and do what is right, ? for my salvation is close at hand and my righteousness will soon be revealed. This conveys Christianity as a religion, is based on the belief that all people should be treated equally and those who fault should be forgiven. It is a religion based on forgiveness and therefore a religion, which places value on justice. Example from the New Testament is Luke 16 The Rich Man and the Beggar, the is about a rich man who was greedy and did not share his wealth nor listed to the guidance that was offered to him while on earth and the beggar who lived a poor but good life and shared what little he had with others. On death both men were judged by God and the rich man asked if he could return to warn his bothers so that they could change their ways and God answered that all people are treated equally and all have the same opportunities to follow his example and that he would not be given special privileged just because he was rich on earth. An example of a similar scenario is the quote â€Å"Blessed Are the Poor in Spirit† found in Matthew 5:1-13 Throughout the ages the faith of Christianity continues to demonstrate that its followers choose to live a life based on justice that comes from equality. The church does not value its members by their individual wealth or social standing and many not for profit organizations are Christian based. These were commenced to give people Christian or otherwise a fair go and an opportunity to participate on an equal standing in our community. Families who take advantage of this assistance do so in times of hardship. Organizations such as Centacare Catholic community services or Anglicare Anglican based are there to service the community, as a whole regardless of religious believes. Their service to the community is to ensure a level of equality for all. Jesus’ teachings were about looking after one another, being equal and not judging or discriminating against someone. Martin Luther was determined to focus on Jesus’ teachings, as the â€Å"somewhat corrupt† practices performed by the Vatican became Particularly troubling to him, as it was against the nature of divine justice, which Jesus had once shown. Martin Luther wanted the adherents of Christianity to be able to access the teachings of Jesus Christ without the Vatican selling indulgences, which was basically the buying of forgiveness of sins instead of repentance and/or penance. In conclusion, I believe the quote Christianity emphasises Justice, while others emphasise compassion is still in practice in today’s society as it was in the days of Jesus.

Demand For Electricity

Demand For Electricity INTRODUCTION If future demand for electricity is to be matched by adequate supply, then it is essential that models are built for estimating accurately, what the future demand for electricity is likely to be. In order to accomplish this, it is necessary that the factors affecting electricity demand are clearly indentified and quantified. It is even more crucial in the case of energy industries because, future energy demand requires investment spending today (due to their huge capital investment requirement and long lead time).[1] In other words, if a country should underestimate its future electricity demand, then it would most likely not make adequate capital investment in the present time which would then result in a shortage of electricity supply (when compared to demand) in the future. One of the most influential factors affecting the demand for electricity is the price of electricity.[2] The price of electricity has since been incorporated into the majority of electricity demand models.[3] This paper tries to examine the effects of the price of electricity in the UK on its own electricity demand. The focus here is to determine the price elasticity of demand for the period 1980-2008 (annual time series data) by the use of a loglinear regression model. The research paper will take the following format. Chapter one is the introduction, chapter two will be the literature review, chapter three will focus on the modelling approach and data analysis and chapter four will be the conclusion and findings. LITERATURE REVIEW Price Elasticity According to economic theory there is an inverse relationship between the price of energy and the quantity of energy demanded. As energy prices rise the quantity of energy demanded falls and vice versa. Given that all other factors are held constant[4]. Economic theory further postulates that the demand for energy is not as responsive to the changes in energy prices as compared to other commodities that are more responsive to their individual prices[5]. Economists define price elasticity as consumers sensitivity to price changes or the degree of responsiveness of changes in quantity demanded to changes in prices and is given by the formula below as: Since price elasticity is the ratio of two percentages, we therefore do not express it in any unit. Price elasticities are usually negative this is due to the inverse relationship between demand and price. Demand elasticities are mainly of two types which are; elastic and inelastic. If the values of elasticity of demand fall within the absolute values of 0 to 1 then demand is said to be inelastic and this can be interpreted thus as a change in price results in a less than proportionate change in quantity demanded. On the other hand if the values of elasticity of demand equals to the absolute value of one or above one, then demand is said to be elastic. In the case where elasticity of demand is equal to the absolute value of 1, it is interpreted as; a change in price leads to a proportionate change in quantity demanded. If the elasticity of demand is greater than the absolute value of 1 then it is interpreted thus as: a change in price results in a more than a proportionate change in quantity demanded. For example in the inelastic range, if price increases by 10 percent on a commodity with a price elasticity of -0.3 then the demand for the good falls by only 3 percent. However, in the case of the elastic range, a commodity with an elasticity of -2.0 would face a fall in demand of 20 percent, if price was to increase by 10 percent. This relationship can be further illustrated in the figure below. Figure 1: Relationship of supply and demand with two demand curves Figure 1 shows a supply curve (S1) and two demand curves which have different elasticities of demand (D1 and D1). D1 is more elastic than D1 (i.e. less steeper). At equilibrium, the supply curve S1, with both demand curves D1 and D1, have a common equilibrium price and quantity at P1 and Q1.Now, let us now assume that the supply curve shifts to the left due to say an increase in the cost of production (i.e. the price of coal used to generate electricity). Then, the new equilibrium point will depend on the nature of the demand curve that is used as shown in figure 2. If the demand curve is relatively elastic at (D1), then prices will rise and demand will fall by a much larger amount when compared to the more inelastic demand curve (D1). Note here that with the inelastic demand curve, the price and quantity demanded (P2 and Q2) are much larger than in the case of a more elastic demand curve at (P2 and Q2). In reality this can be explained by the fact that, if the demand for a commodity is inelastic then, any increase in costs (for example generation costs as mentioned above) can easily be passed on to the consumers without much reduction in supply, hence the larger price. On the other hand if the demand for the commodity were to be elastic then only a much smaller portion of the cost increase would be passed on to the consumer. Figure 2: Shows the effects of a shift in the Supply Curve We can also see the effects of a shift in the demand curve on price and quantity. If we assume that demand curves were to shift outward to the right (i.e. increases) from (D1 to D2) and (D1 to D2) while supply is held constant then with a more elastic demand curve the equilibrium price and quantity (P2 and Q2) would be much lower than if demand were to be inelastic (i.e. P2 and Q2). Figure 3: Effects of a shift in the Demand Curve From the three above illustrations it is quite clear that the resulting impact of changes in supply or demand on equilibrium price and quantity will vary in accordance to the nature of product elasticity. Price elasticities can be used to show how consumer demand responds to changes in price as well as the ease at which individuals can switch over to a substitute, when commodity prices go up. A consumer who has a fixed income has three options of responding to price changes in the short term; (a the consumer can switch over to a substitute; b) they can purchase less of the commodity without any additional purchase of a substitute; or (c he or she can still buy the same quantity of good while reducing his or her consumption of other commodities that make up their total expenditure. In the case of electricity the degree at which it can be substituted is very limited. Electricity can be used mainly for heating, lightening or a wide range of electric appliances such as (computers, television sets, printers, irons etc.). In the case of heating, a consumer may substitute the use of electricity for natural gas (and in the case of less developed countries may even substitute it for it for kerosene or firewood). However, the consumer also has the option of switching over to an appliance that uses a more energy conserving source. For end uses such as power supply for television sets, electricity has no substitutes. The consumer also has the option of purchasing a more efficient television set and maintaining the same level of service while using less electricity. Replacing appliances such as television sets may involve the change of a relatively expensive appliance and as such would take some time to do so. Since, this will involve a first initial capital outlay which i n turn depends on the income of the consumer, frequency of wage payment and payment of bills schedules etc. The time period required by consumers to substitute a relatively expensive appliance in response to higher energy prices is usually referred to as the long-run adjustment time period. On this the basis of this analysis, it is expected that the price elasticity of demand is usually inelastic in the short run and more elastic in the long run. This is because in the short run the consumers options of responding to higher electricity prices are limited i.e. he is restricted to reactions such as, reducing his or her level of appliance utilisation (for example running the heater for lesser hours of the day) or reducing his expenditure on other commodities to maintain the same level of electricity consumption. In the long run however, his options of responding to high energy prices are increased compared to the options he had in the short run. In the long run the consumer can fully respond to price changes by the purchase of appliances that are more efficient and/or the purchase of appliances that use a cheaper energy source. That is why in the long run elasticities tend toward a more elastic range than in the short run. Earlier Literature on Price Elasticity of Electricity Demand Earlier literature on electricity demand has revealed that the price elasticity of demand for electricity is relatively inelastic in the short run and tend to be relatively more elastic in the long run. The previous works written on price elasticity of demand are far too much to be fully discussed in this research. Therefore we shall focus on only the summary of a few. Taylor (1975) wrote one of the first literatures on electricity demand surveys. After carrying out reviews on various existing studies of commercial, industrial and residential electricity demand, he reported the following: (a in the case of residential demand for electricity, short term price elasticity ranged from -0.13 to -0.90 while long run price elasticities ranged from near 0 to -2.0. In the case of commercial demand, price elasticities were valued at -0.17 for the short run and -1.36 for the long run[7]. Boone kamp (2007) using the bottom up model on an annual data series for the period 1990-2000 reported that the household long term price elasticity ranged from -0.09 to 0.13[8]. Pouris (1987) conducted an analysis for the elasticity of demand for electricity for South Africa using data for the period (1950-1983) and determined that the long term price elasticity of electricity demand for the period was -0.90.[9] Bjoner and Jensen (2002) using a loglinear fixed effects model on panel data for the period of (1983-1996) discovered that short term price elasticity to be -0.479.[10] Filippini and Pachuari (2002) using a loglinear model on a monthly household panel data series discovered that the household short term price elasticity for electricity ranged from -0.16 to 0.39.[11] Zimmerman and Bohi (1984) carried out a detailed review of existing studies of energy demand. They reported that general consensus figures for residential price elasticity of electricity were -0.2 in the short run and -0.7 in the long run. The range of estimates in commercial electricity was too volatile to provide any consensus on values.[12] Al Faris (2002) used an error correction model to estimate short term price elasticity for UAE, Kuwait, Oman, Qatar and Bahrain to range from-0.04 to- 0.18.[13] The analysis carried out was based on an annual time series data for the period 1970-1997. Garcia Cerruti (2000) calculated the price elasticity for residential demand for electricity in California to have an estimated mean value of -0.17.[14] In summary, earlier literature show that price elasticity of electricity demand are normally inelastic in the short run and tends to be more elastic in the long run. However, on the whole price elasticity of electricity demand are usually inelastic (i.e. the absolute value of the co-efficient of price elasticity is usually below 1). MODELLING APPROACH AND DATA ANALYSIS According to Lin (2003)[15] he identified that there were three major factors affecting the demand for electricity in any country which were, electricity prices (tariff), GDP (Gross Domestic Product) and population. He went further to say that there were other factors as well contributing to the price of electricity which varied with different countries. Such factors includes nature of weather (i.e. people tend to use more electricity for heating purposes during cold seasons than in hot seasons) and changes in the structure of the economy. Pouris (1987)[16] identified the two major factors affecting the demand for electricity as price and GDP. Using the common independent variables identified by both Lin and Pouris, we have the following model; Log EDt = a + b1LogPEt + b2 LogYt + µEquation Where: EDt = Total electricity demand in period in a given year (Gwh) PEt = Average price of electricity in constant terms for a given year ( £/Kwh) Yt = GDP of country for period t in constant Billion Pounds a = Constant b1 =Price elasticity of electricity demand b2 =Income elasticity of electricity demand  µ= Disturbance term (represents all other factors affecting the demand for electricity) We use the log functional form because it enables us easily determine the price elasticity for electricity demand which is the regression coefficient of price. The price elasticity of demand for electricity is also assumed to be constant.[17] The data used for the period is in constant terms and aggregated at the national level. We express our data in constant terms because we would like to take out the effects of inflation. The data used is aggregated at a national level because it tends to provide a more stable relationship between independent and dependent variables. Pouris (1987)[18] cited Ehrenbergs (1975)[19] work in which he (Ehrenberg) argued that the advances in physical sciences are to a great extent due to the fact that simple relationships (laws) are achievable because they usually account for the collective behaviour of million entities. Pouris (1987) then argued further that, the success of finding laws in social sciences would be in likely areas where behaviour of large individuals or objects can be aggregated. From the above table we can see that the price elasticity of demand for electricity (for the UK) is approximately -0.15 which agrees with economic theory that; (a elasticities of demand are inversely related to price as shown by the negative coefficient of price elasticity and (b price elasticity of demand for electricity tends to be inelastic i.e. having an absolute value below one. Also we do not reject the result due to the high R2 = 0.9688 (co-efficient of determination) and the fact that the result is statistically significant i.e. the absolute t values for real GDP and real electricity prices are above 2. While their (real GDP and real electricity prices) P values are below 5%. The table below shows the data (for U.K.) used in carrying out the regression analysis. The demand for electricity data and average electricity prices were sourced from the Economic and Social Data Services (ESDS) website. While the Real GDP and Consumer prices were obtained from the International Monetary Fund (IMF) website CONCLUSION/FINDINGS The price elasticity of electricity demand for the period (2008-2020) is about -0.15, which is consistent with economic theory that the co-efficient of price elasticities tend to have negative values and that the price elasticities for electricity tend to be inelastic. If we assume that the price elasticity for all organization and individuals in the U.K. lies close to this value (-0.15) and is constant through out time, then such information could have various implications for the economy. Firstly, an inelastic demand for electricity, would mean that there would be little or no government intervention required on the supply side (existing producers and suppliers) to ensure that producers and suppliers of electricity are able to breakeven (recover costs from generated revenue). This is because an inelastic demand for electricity (with respect to price) would mean that whenever there is an increase in demand and producers have to increase their supply in order to match the rising demand, the costs associated with increasing supply can easily be passed on to the consumer. As such, the government could be able to focus on other activities such as the provision and maintenance of public roads, hospital, and schools. Secondly, it would enable the government easily achieve renewable energy targets set in the power generating sector, due to the fact that the potential increases in costs arising from setting renewable energy targets can easily be transferred to the consumer (due to inelastic nature of electricity demand). The government should however ensure that the targets are set in a fair main manner such that the impact of the targets are felt by all power generators in a similar way and that no undue advantage is given to any one single producer due to the implementation of such targets. Furthermore the government should ensure that the targets are set in such a way that it does not increase tariffs too much so that consumers cannot easily afford their bills. Which in turn would then reduce demand drastically (since the consumers in the short run have the option of turning of their appliances) and hence, adversely affect supply as producers may not be able to recover all their fixed cost. If t his effect (rising prices drastically affecting demand) is unavoidable then the government should adopt policies that could assist in improving the disposable income of its citizens.
